Christopher Carfi on his Social Customer Manifesto
blog has a great post[Let's Look at the Big Picture
]that talks about Information as the new form of "money" by looking at how the concept of "money" wasfirst formed 150 years ago. Here's an excerpt:
Lesson 1: "Money" was very fragmented for a very long period of time after the colonization of North America
"Money" as we think of it in the form of cash/paper currency has only been around for about 150 years. Over a period of almost two hundred years both before and after that time, a number of fragmented methods were used to exchange value.
Lesson 2: Everybody needs to win
After the ideas of "cash" and "checks" had taken hold and become widespread, there were still many inefficiencies in the system. Cash is cumbersome, and subject to loss. Checks may bounce. This continued until the mid-1900's.
Enter the credit card.*
The credit card resonated with both customers and vendors because both parties received benefits.
Now, the widespread usage of credit cards was not something the occurred overnight. Instead, it was something that occurred over a generation. In 1970, only 16% of American households had credit cards. However, by 1995, that number had climbed to 65%.
We are now looking at Information in much the same way. It is fragmented, it is used to represent value, it is hoarded by some, shared by others. In much that "brown" is the new "black", does that mean "information" is the new"money"?
A related blog post from Shawn over at Anecdote discusses a panelist discussion of Albert Camus' work,The Stranger. Here is an excerpt:
... meaning is not pre-inscribed in the world around us and we are continuously seeking meaning in an inherently meaningless world. I almost toppled off the step machine. Do we live in an inherently meaningless world? On first thought I think the answer is yes. The onus is on us to make sense of our world.
And here is where information, by itself, is not of value unless people place value on it. Just as people valued Wampum and Furs, and could therefore trade it for other goods, people trade information for other itemsof value. But the onus is on us to make sense of the information, to determine the meaning of it, and use thisto help drive business or other accomplishments.
Are you leveraging information as well as investors leverage other people's money? If not, IBM can help.

It's already the 11th of January, and thought I would take a break from technology tofocus on my [New Year's Resolutions
]from last year, and make some new ones for 2008.
Last Year's Resolutions:
- Blog on a more consistent frequency
In [Data Center Resolutions], I resolved to post one to five entries per week, and I think I made good on this one. When I was assembling mybook [Inside System Storage: Volume I], I noticed an evolution month by month since I made this resolution.
- Reduce my waist down to 35 inches
Rather than a target weight, I chose a target waist measurement, but did not quite make this one. I did keep up with my weekly exercise regime, but we recently installed an "ice cream freezer" here at work, and I have failed to resist temptation.
- Reduce, Reuse and Recycle
In my post [Stayingon Budget], I resolved to "reduce, reuse and recycle". I have taken measures to de-clutter and simplify mylife, and already things are paying off. So I am happy about this one.
- Learn to Better use Lotus Notes and Office 2007 software
In my post [Honeyour Tools and Skills], I resolved to learn how to better use Lotus Notes and Office 2007. We never got Office 2007.In a surprise move, IBM put out Lotus Symphony, an Office 2007 replacement. Lotus Symphony works on IBM's three approved recognized desktop platforms (Windows XP, Linux and Mac OS X). Here's a collection of [IBM Press Releases about Lotus Symphony].
I did learn how to better use Lotus Notes,thanks to Alan Lepofsky's blog [IBM Lotus Notes Hints, Tips, and Tricks].Ironically, the best help for dealing with Lotus Notes was not the software itself, but the skills in handling emailin general. This includes:
- Write shorter notes. Down to [five sentences] in some cases.
- Resist the urge to copy the world, and better use "bcc" to be kind to upper management on "reply all" respondents.
- Avoid attaching large documents, but use URL's to NAS file shares, websites, or [YouSendIt.com] instead. Obviously, the recipient has to have access to whatever you point to, but it greatly reduces total email volume and improves transmission over wireless.
- Delegate. A lot of times I was the "middleman" between someone asking a question, and someone else Iknew had the answer. Now, I just introduce them together and step out of the way.
- Checking email only a few times a day. I use to check my email every 5-10 minutes, now only 2-4 times per day.
- Laugh More
In my post, [Lighten Up], I resolved to laugh more, stretch more, get enough sleep, and listen to music more. I participated in monthly[Tucson Laughter Club]events, incorporated stretching in my weekly exercise program, have gotten more sleep, and rediscovered some of my older music that I hadn't listened to in a while. Overall, I feel happy I met this one.
My New Year's Resolutions for 2008:
- Improve my writing skills
Going back through my past blog postings, some of my sentences and paragraphs were frightful. I resolve toimprove my sentence and paragraph structure, and make better use of HTML tags to improve the layout andformatting.
- Improve my HTML and Web design skills
- Contribute to the OLPC Foundation
Last year, as a "Day 1 Donor", I had donated to this important charitable organization to help educate the childrenof third world nations. This year, I plan to learn Python and other programming languages used on the XO laptop,and see how I can contribute my skills and expertise on the OLPC forums.
- Eat Healthier and Drink more
I think my downfall with last year's resolution was that it was merely a goal, 35 inch waist, rather thana "call for action". This year, I plan to eat more fish, salads, whole grains and other heart-healthy foods.
While many people resolve to "Quit Drinking", I need to drink more. My doctor, my personaltrainer, and even my interpreter teams, have asked me to do so. We live in Tucson, Arizona, during a centuryof global warming, and dehydration can cause stress on the body.
- Attend more movies and film-making events
Last year, I joined the Tucson Film Society, and produced[my first film], part of which was filmedfrom Bogota, Colombia. I got invited to see a lot of independent films, premieres, and film-maker events, but did not attend many. I resolve to attend more in 2008.
- Get better Organized
Moving offices from one building to another brought to light that I wasn't well organized. While I havemade some efforts to de-clutter my home, I need to step this up to my work as well.
I decided to start with something very non-tech, a [Hipster PDA]. I have nowmet or heard several people who use this approach successfully, and have decided to give it a try.
Hopefully, this list might inspire you to come up with your own resolutions. Not surprisingly, writing them in a public forum helped me keep most of them, and stick to my resolutions throughout the year.

Whew! I am glad that is over. The BarryB circus has left town, he has decided to [move on to other topics
], and I am now to clean up the ["circus gold"
] leftbehind. I would like to remind everyone that all of these discussions have been about the architecture,not the product. IBM will come out withits own version of a product based on Nextra later in 2008, which may be different than the product that XIV currentlysells to its customers.
- RAID-X does not protect against double-drive failures as well as RAID-6, but it's very close
BarryB calls this the "Elephant in the room", that RAID-6 protects better against double-drive failures. I don't dispute that. He also credits me with the term "RAID-X", but I got this directly from the XIV guys. It turns out this was already a term used among academic research circles for [distributed RAID environments]. Meanwhile, Jon Toigo feels the term RAID-X sounds like a brand of bug spray in his post[XIV Architecture: What’s Not to Like?]Perhaps IBM can change this to RAID-5.99 instead.
If you measure risk of a second drive failing during the rebuild or re-replication process ofa first drive failure, you can measure the exposure by multiplying the amount of GB at risk by thenumber of hours that the second failure could occur, resulting in a unit of "GB-hours". Here Ilist best-case rebuild times, your mileage may vary depending on whether other workloads existon the system competing for resources. Notice that 8-disk configurations of RAID-10 and RAID-5for smaller FC disk are in the triple digits, and larger SATA disk in five digits, but that with RAID-X it is only single digits. That is orders of magnitude closer to the ideal.
For each RAID type, the risk is proportional to the square of the individual drive size.Double the drive size causes the risk to be four times greater.This is not the first time this has been discussed. In [Is RAID-5 Getting Old?], Ramskovquotes NetApp's response in Robin Harris' [NetApp Weighs In On Disks]:
...protecting online data only via RAID 5 today verges on professional malpractice.
As disks get older, RAID-6 will not be able to protect against 3-drive failures. A similar chartabove could show the risk to data after the second drive fails and both rebuilds are going on,compared to the risk of a third drive failure during this time. The RAID-X scheme protects muchbetter against 3-drive failures than RAID-6.
- Nothing in the Nextra architecture prevents a RAID-6, Triple-copy, or other blob-level scheme
In much the same way that EMC Centera is RAID-5 based for its blobs, there is nothing in the Nextra architecturethat prevents taking additional steps to provide even better protection, using a RAID-6 scheme, making three copiesof the data instead of two copies, or something even more advanced. The current two-copy scheme for RAID-X is betterthan all the RAID-5 and RAID-10 systems out in the marketplace today.
- Mirrored Cache won't protect against Cosmic rays, but ECC detection/correction does
BarryB incorrectly states that since some implementations of cache are non-mirrored, that this implies they are unprotected against Cosmic rays. Mirroring does not protect against bit-flips unless both copies arecompared for differences. Unfortunately, even if you compared them, the best you can do is detect theyare different, there is no way of knowing which version is correct.Mirroring cache is normally done to protect uncommitted writes. Reads in cacheare expendable copies of data already written to disk, so ECC detection/correction schemes are adequateprotection. ECC is like RAID for DRAM memory. A single bit-flip can be corrected, multiple bit-flipscan be detected. In the case of detection, the cache copy is discarded and read fresh again from disk.IBM DS8000, XIV and probably most other major vendor offerings use ECC of some kind. BarryB is correctthat some cheaper entry-level and midrange offerings from other vendors might cut corners in this area.I don't doubt BarryB's assertion that the ECC method used in the EMC products may be differently implemented than theECC in the IBM DS8000, but that doesn't mean the IBM DS8000's ECC implementation is flawed.
ECC protection is important for all RAID systems that perform rebuild, and even more importantthe larger the GB-hours listed in the table above.
- XIV is designed for high-utilization, not less than 50 percent
I mentioned that the typical Linux, UNIX or Windows LUN is only 30-50 percent full, and perhaps BarryBthought I was referring to the typical "XIV customer". This average is for all disk storage systems connectedto these operating systems, based on IBM market research and analyst reports. The XIV is expected to run at much higher utilization rates, and offers features like "thin provisioning" and "differential snapshot" to make this simple to implement in practice.
- Pre-emptive Self-Repair
Most often, disks don't fail without warning. Usually, they give out temporary errors first, and then fail permanently.The XIV architecture allows for pre-emptive self-repair, initiating the re-replication process after detecting temporary errors, rather than waiting for a complete drive failure.
I had mentioned that this process used "spare capacity, not spare drives" but I was notified that there are three spare drives per system to ensure that there is enough spare capacity, so I stand corrected.
New drives don't have to match the same speed/capacity as the new drives, so three to five years from now, whenit might be hard to find a matching 500GB SATA drive anymore, you won't have to.
- No RAID scheme eliminates backups or Business Continuity Planning
The XIV supports both synchronous and asynchronous disk mirroring to remote locations. Backup software willbe able to backup data from the XIV to tape. A double drive failure would require a "recovery action", eitherfrom the disk mirror, or from tape, for the few GB of data that need to be recovered.
A third alternative is to allow end-users to receive backups of their own user-generated content. For example, I have over 15,000 photos uploaded over the past six years to Kodak Photo Gallery, which I use to share with my friends and family. For about $180 US dollars, they will cut DVDs containing all of my uploaded files and send them to me, so that I do not have to worry about Kodak losing my photos.In many cases, if a company or product fails to deliver on its promises, the most you will get is your money back, but for "free services" like HotMail, FreeDrive, FlickR and others, you didn't pay anything in the first place, andthey may point this limitation of liability in the "terms of service".
- XIV can be used for databases and other online transaction processing
The XIV will have FCP and iSCSI interfaces, and systems can use these to store any kind of data you want. I mentionedthat the design was intended for large volumes of unstructured digital content, but there is nothing to prevent the use of other workloads. In today's Wall Street Journal article[To Get Back Into the Storage Game, IBM Calls In an Old Foe]:
Today, XIV's Nextra system is used by Bank Leumi, a large Israeli bank, and a few other customers for traditional data-storage tasks such as recording hundreds of transactions a minute.
BarryB, thanks for calling the truce. I look forward to talking about other topics myself. These past two weeks have been exhausting!

In my post yesterday [Spreading out the Re-Replication process
], fellow blogger BarryB [aka The Storage Anarchist
]raises some interesting points and questions in the comments section about the new IBM XIV Nextra architecture.I answer these below not just for the benefit of my friends at EMC, but also for my own colleagues within IBM,IBM Business Partners, Analysts and clients that might have similar questions.
- If RAID 5/6 makes sense on every other platform, why not so on the Web 2.0 platform?
Your attempt to justify the expense of Mirrored vs. RAID 5 makes no sense to me. Buying two drives for every one drive's worth of usable capacity is expensive, even with SATA drives. Isn't that why you offer RAID 5 and RAID 6 on the storage arrays that you sell with SATA drives?Let's take a look at various disk configurations, for example 3TB on 750GB SATA drives:
And if RAID 5/6 makes sense on every other platform, why not so on the (extremely cost-sensitive) Web 2.0 platform? Is faster rebuild really worth the cost of 40+% more spindles? Or is the overhead of RAID 6 really too much for those low-cost commodity servers to handle.
- JBOD: 4 drives
- JBOD here is industry slang for "Just a Bunch of Disks" and was invented as the term for "non-RAID".Each drive would be accessible independently, at native single-drive speed, with no data protection. Puttingfour drives in a single cabinet like this provides simplicity and convenience only over four separate drivesin their own enclosures.
- RAID-10: 8 drives
- RAID-10 is a combination of RAID-1 (mirroring) and RAID-0 (striping). In a 4x2 configuration, data is striped across disks 1-4,then these are mirrored across to disks 5-8. You get performance improvement and protection against a singledrive failure.
- RAID-5: 5 drives
- This would be a 4+P configuration, where there would be four drives' worth of data scattered across fivedrives. This gives you almost the same performance improvement as RAID-10, similar protection againstsingle drive failure, but with fewer drives per usable TB capacity.
- RAID-6: 6 drives
- This would be a 4+2P configuration, where the first P represents linear parity, and the second represents a diagonal parity. Similar in performance improvement as RAID-5, but protects against single and double drive failures, and still better than RAID-10 in terms of drives per TB usable capacity.
For all the RAID configurations, rebuild would require a spare drive, but often spares are shared among multiple RAID ranks, not dedicated to a single rank. To this end, you often have to have several spares per I/O loop, and a different set of spares for each kind of speed and capacity. If you had a mix of 15K/73GB, 10K/146GB, and 7200/500GB drives, then you would have three sets of spares to match.
In contrast, IBM XIV's innovative RAID-X approach doesn't requireany spare drives, just spare capacity on existing drives being used to hold data. The objects can be mirroredbetween any two types of drives, so no need to match one with another.
All of these RAID levels represent some trade-off between cost, protection and performance, and IBM offers each of theseon various disk systems platforms. Calculating parity is more complicated than just mirrored copies, but this can be done with specialized chips in cache memory to minimize performance impact.IBM generally recommends RAID-5 for high-performance FC disk, and RAID-6 for slower, large capacity SATA disk.
However, the questionassumes that the drive cost is a large portion of the overall "disk system" cost. It isn't. For example,Jon Toigo discusses the cost of EMC's new AX4 disk system in his post [National Storage Rip-Off Day]:
- EMC is releasing its low end Clariion AX4 SAS/SATA array with 3TB capacity for $8600. It ships with four 750GB SATA drives (which you and I could buy at list for $239 per unit). So, if the disk drives cost $956 (presumably far less for EMC), that means buyers of the EMC wares are paying about $7700 for a tin case, a controller/backplane, and a 4Gbps iSCSI or FC connector. Hmm.
- Dell is offering EMC’s AX4-5 with same configuration for $13,000 adding a 24/7 warranty.
(Note: I checked these numbers. $8599 is the list price that EMC has on its own website. External 750GB drivesavailable at my local Circuit City ranged from $189 to $329 list price. I could not find anything on Dell'sown website, but found [The Register] to confirm the $13,000 with 24x7 warranty figure.)
Disk capacity is a shrinking portion of the total cost of ownership (TCO). In addition to capacity, you are paying forcache, microcode and electronics of the system itself, along with software and services that are included in the mix,and your own storage administrators to deal with configuration and management. For more on this, see [XIV storage - Low Total Cost of Ownership].
- EMC Centera has been doing this exact type of blob striping and protection since 2002
As I've noted before, there's nothing "magic" about it - Centera has been employing the same type of object-level replication for years. Only EMC's engineers have figured out how to do RAID protection instead of mirroring to keep the hardware costs low while not sacrificing availability.
I agree that IBM XIV was not the first to do an object-level architecture, but it was one of the first to apply object-level technologies to the particular "use case" and "intended workload" of Web 2.0 applications.
RAID-5 based EMC Centera was designed insteadto hold fixed-content data that needed to be protected for a specific period of time, such as to meet government regulatory compliance requirements. This is data that you most likelywill never look at again unless you are hit with a lawsuit or investigation. For this reason, it is important to get it on the cheapest storage configuration as possible. Before EMC Centera, customers stored this data on WORM tape and optical media, so EMC came up with a disk-only alternative offering.IBM System Storage DR550 offers disk-level access for themost recent archives, with the ability to migrate to much less expensive tape for the long term retention. The end result is that storing on a blended disk-plus-tape solution can help reduce the cost by a factor of 5x to 7x, making RAID level discussion meaningless in this environment. For moreon this, see my post [OptimizingData Retention and Archiving].
While both the Centera and DR550 are based on SATA, neither are designed for Web 2.0 platforms.When EMC comes out with their own "me, too" version, they will probably make a similar argument.
- IBM XIV Nextra is not a DS8000 replacement
Nextra is anything but Enterprise-class storage, much less a DS8000 replacement. How silly of all those folks to suggest such a thing.
I did searches on the Web and could not find anybody, other than EMC employees, who suggested that IBM XIV Nextra architecture represented a replacement for IBM System Storage DS8000. The IBM XIV press release does not mentionor imply this, and certainly nobody I know at IBM has suggested this.
The DS8000 is designed for a different "use case" andset of "intended workloads" than what the IBM XIV was designed for. The DS8000 is the most popular disk systemfor our IBM System z mainframe platform, for activities like Online Transaction Processing (OLTP) and large databases, supporting ESCON and FICON attachment to high-speed 15K RPM FC drives. Web 2.0 customers that might chooseIBM XIV Nextra for their digital content might run their financial operations or metadata search indexes on DS8000.Different storage for different purposes.
As for the opinion that this is not "enterprise class", there are a variety of definitions that refer to this phrase.Some analysts look at "price band" of units that cost over $300,000 US dollars. Other analysts define this as beingattachable to mainframe servers via ESCON or FICON. Others use the term to refer to five-nines reliability, havingless than 5 minutes downtime per year. In this regard, based on the past two years experience at 40 customer locations,I would argue that it meets this last definition, with non-disruptive upgrades, microcode updates and hot-swappable components.
By comparison, when EMC introduced its object-level Centera architecture, nobody suggested it was the replacement for their Symmetrix or CLARiiON devices. Was it supposed to be?
- Given drive growth rates have slowed, improving utilization is mandatory to keep up with 60-70 percent CAGR
Look around you, Tony- all of your competitors are implementing thin provisioning specifically to drive physical utilization upwards towards 60-80%, and that's on top of RAID 5/RAID 6 storage and not RAID 1. Given that disk drive growth rates and $/GB cost savings have slowed significantly, improving utilization is mandatory just to keep up with the 60-70% CAGR of information growth.
Disk drive capacities have slowed for FC disk because much of the attention and investment has been re-directed to ATA technology. Dollar-per-GB price reduction is slowing for disks in general, as researchers are hitting physicallimitations to the amount of bits they can pack per square inch of disk media, and is now around 25 percent per year.The 60-70 percent Compound Annual Growth Rate (CAGR) is real, and can be even growing faster for Web 2.0providers. While hardware costs drop, the big ticket items to watch will be software, services and storage administrator labor costs.
To this end, IBM XIV Nextra offers thin provisioning and differential space-efficient snapshots. It is designed for 60-90 percent utilization, and can be expanded to larger capacities non-disruptively in a very scalable manner.
Well, I hope that helps clear some things up.

On his The Storage Architect
blog, Chris Evans wrote [Twofor the Price of One
]. He asks: why use RAID-1 compared to say a 14+2 RAID-6 configuration which would be much cheaper in terms of the disk cost?
Perhpaps without realizing it, answers itwith his post today [XIV part II
So, as a drive fails, all drives could be copying to all drives in an attempt to ensure the recreated lost mirrors are well distributed across the subsystem. If this is true, all drives would become busy for read/writes for the rebuild time, rather than rebuild overhead being isolated to just one RAID group.
Let me try to explain. (Note: This is an oversimplification of the actual algorithm in an effortto make it more accessible to most readers, based on written materials I have been provided as partof the acquisition.)
In a typical RAID environment, say 7+P RAID-5, you might have to read 7 drives to rebuild one drive, and in the case of a 14+2 RAID-6, reading 15 drives to rebuild one drive. It turns out the performance bottleneck is the one driveto write, and today's systems can rebuild faster Fibre Channel (FC) drives at about 50-55 MB/sec, and slower ATA disk at around 40-42 MB/sec. At these rates, a 750GB SATA rebuild would take at least 5 hours.
In the IBM XIV Nextra architecture, let's say we have 100 drives. We lose drive 13, and we need to re-replicate any at-risk 1MB objects.An object is at-risk if it is the last and only remaining copy on the system. A 750GB that is 90 percent full wouldhave 700,000 or so at-risk object re-replications to manage. These can be sorted by drive. Drive 1 might have about 7000 objects that need re-replication, drive 2might have slightly more, slightly less, and so on, up to drive 100. The re-replication of objects on these other 99 drives goes through three waves.
- Wave 1
Select 49 drives as "source volumes", and pair each randomly with a "destination volume". For example, drive 1 mapped todrive 87, drive 2 to drive 59, and so on. Initiate 49 tasks in parallel, each will re-replicate the blocks thatneed to be copied from the source volume to the destination volume.
- Wave 2
50 volumes left.Select another 49 drives as "source volumes", and pair each with a "destination volume". For example, drive 87 mapped todrive 15, drive 59 to drive 42, and so on. Initiate 49 tasks in parallel, each will re-replicate the blocks thatneed to be copied from the source volume to the destination volume.
- Wave 3
Only one drive left. We select the last volume as the source volume, pair it off with a random destination volume,and complete the process.
Each wave can take as little as 3-5 minutes. The actual algorithm is more complicated than this, as tasks complete early the source and volumes drives are available for re-assignment to another task, but you get the idea. XIV hasdemonstrated the entire process, identifying all at-risk objects, sorting them by drive location, randomly selectingdrive pairs, and then performing most of these tasks in parallel, can be done in 15-20 minutes. Over 40 customershave been using this architecture over the past 2 years, and by now all have probably experienced at least adrive failure to validate this methodology.
In the unlikely event that a second drive fails during this short time, only one of the 99 task fails. The other 98 tasks continue to helpprotect the data. By comparison, in a RAID-5 rebuild, no data is protected until all the blocks are copied.
As for requiring spare capacity on each drive to handle this case, the best disks in production environments aretypically only 85-90 percent full, leaving plenty of spare capacity to handle re-replication process. On average,Linux, UNIX and Windows systems tend to only fill disks 30 to 50 percent full, so the fear there is not enough sparecapacity should not be an issue.
The difference in cost between RAID-1 and RAID-5 becomes minimal as hardware gets cheaper and cheaper. For every $1 dollar you spend on storage hardware, you spend $5-$8 dollars managing the environment. As hardware gets cheaper still, it might even be worth making three copies of every 1MB object, the parallel processto perform re-replications would be the same. This could be done using policy-based management, some data gets triple-copied, and other data gets only double-copied, based on whether the user selected "premium" or "basic" service.
The beauty of this approach is that it works with 100 drives, 1000 drives, or even a million drives. Parallel processingis how supercomputers are able to perform feats of amazing mathematical computations so quickly, and how Web 2.0services like Google and Yahoo can perform web searches so quickly. Spreading the re-replication process acrossmany drives in parallel, rather than performing them serially onto a single drive, is just one of the many uniquefeatures of this new architecture.

Wrapping up my week's theme on IBM's acquisition XIV, we have gotten hundreds of positive articles and reviews in the press, but has caused quite a stir with the[Not-Invented-Here
] folks at EMC.We've heard already from EMC bloggers [Chuck Hollis
] and [Mark Twomey
].The latest is fellow EMC blogger BarryB's missive [Obligatory "IBM buys XIV" Post
], which piles on the "Fear, Uncertainty and Doubt" [FUD
], including this excerpt here:
In a block storage device, only the host file system or database engine "knows" what's actually stored in there. So in the Nextra case that Tony has described, if even only 7,500-15,000 of the 750,000 total 1MB blobs stored on a single 750GB drive (that's "only" 1 to 2%) suddenly become inaccessible because the drive that held the backup copy also failed, the impact on a file system could be devastating. That 1MB might be in the middle of a 13MB photograph (rendering the entire photo unusable). Or it might contain dozens of little files, now vanished without a trace. Or worst yet, it could actually contain the file system metadata, which describes the names and locations of all the rest of the files in the file system. Each 1MB lost to a double drive failure could mean the loss of an enormous percentage of the files in a file system.
And in fact, with Nextra, the impact will be across not just one, but more likely several dozens or even hundreds of file systems.
Worse still, the Nextra can't do anything to help recover the lost files.
Nothing could be further from the truth. If any disk drive module failed, the system would know exactly whichone it was, what blobs (binary large objects) were on it, and where the replicated copies of those blobs are located. In the event of a rare double-drive failure, the system would know exactly which unfortunate blobs were lost, and couldidentify them by host LUN and block address numbers, so that appropriate repair actions could be taken from remote mirrored copies or tape file backups.
Second, nobody is suggesting we are going to put a delicateFAT32-like Circa-1980 file system that breaks with the loss of a single block and requires tools like "fsck" to piece back together. Today's modern file systems--including Windows NTFS, Linux ext3, and AIX JFS2--are journaled and have sophisticated algorithms tohandle the loss of individual structure inode blocks. IBM has its own General Parallel File System [GPFS] and corresponding Scale out File Services[SOFS], and thus brings a lotof expertise to the table.Advanced distributed clustered file systems, like [Google File System] and Yahoo's [Hadoop project] take this one step further, recognizing that individual node and drive failures at the Petabyte-scale are inevitable.
In other words, XIV Nextra architecture is designed to eliminate or reduce recovery actions after disk failures, not make them worse. Back in 2003, when IBM introduced the new and innovative SAN Volume Controller (SVC), EMCclaimed this in-band architecture would slow down applications and "brain-damage" their EMC Symmetrix hardware.Reality has proved the opposite, SVC can improve application performance and help reduce wear-and-tear on the manageddevices. Since then, EMC acquired Kashya to offer its own in-band architecture in a product called EMC RecoverPoint, that offers some of the features that SVC offers.
If you thought fear mongering like this was unique to the IT industry, consider that 105years ago, [Edison electrocuted an elephant]. To understand this horrific event, you have to understand what was going on at the time.Thomas Edison, inventor of the light bulb, wanted to power the entire city of New York with Direct Current(DC). Nikolas Tesla proposed a different, but more appropriate architecture,called Alternating Current(AC), that had lower losses over distances required for a city as large and spread out as New York. But Thomas Edison was heavily invested in DC technology, and would lose out on royalties if ACwas adopted.In an effort to show that AC was too dangerous to have in homes and businesses, Thomas Edison held a pressconference in front of 1500 witnesses, electrocuting an elephant named Topsy with 6600 volts, and filmed the event so that it could be shown later to other audiences (Edison invented the movie camera also).
Today's nationwide electric grid would not exist without Alternating Current.We enjoy both AC for what it is best used for, and DC for what it is best used for. Both are dangerous at high voltage levels if not handled properly. The same is the case for storage architectures. Traditional high-performance disk arrays, like the IBM System Storage DS8000, will continue to be used for large mainframe applications, online transaction processing and databases. New architectures,like IBM XIV Nextra, will be used for new Web 2.0 applications, where scalability, self-tuning, self-repair,and management simplicity are the key requirements.
(Update: Dear readers, this was meant as a metaphor only, relating the concerns expressed above thatthe use of new innovative technology may result in the loss or corruption of "several dozen or even hundreds of file systems" and thus too dangerous to use, with an analogy on the use of AC electricity was too dangerous to use in homes. To clarify, EMC did not re-enact Thomas Edison's event, no animalswere hurt by EMC, and I was not trying to make political commentary about the current controversy of electrocution as amethod of capital punishment. The opinions of individual bloggers do not necessarily reflect the official positions of EMC, and I am not implying that anyone at EMC enjoys torturing animals of any size, or their positions on capital punishment in general. This is not an attack on any of the above-mentioned EMC bloggers, but rather to point out faulty logic. Children should not put foil gum wrappers in electrical sockets. BarryB and I have apologized to each other over these posts for any feelings hurt, and discussion should focus instead on the technologies and architectures.)
While EMC might try to tell people today that nobody needs unique storage architectures for Web 2.0 applications, digital media and archive data, because their existing products support SATA disk and can be used instead for these workloads, they are probably working hard behind the scenes on their own "me, too" version.And with a bit of irony, Edison's film of the elephant is available on YouTube, one of the many Web 2.0 websites we are talking about. (Out of a sense of decency, I decided not to link to it here, so don't ask)

Yesterday's announcement that IBM had acquired XIV to offer storage for Web 2.0 applicationsprompted a lot of discussion in both the media and the blogosphere. Several indicated thatit was about time that one of the major vendors stepped forward to provide this, and it madesense that IBM, the leader in storage hardware marketshare, would be the first. Others were perhaps confused on what is unique with Web 2.0 applications. What has changed?
I'll use this graphic to help explain how we have transitioned through three eras of storage.
- The first era: Server-centric
In the 1950s, IBM introduced both tape and disk systems into a very server-centric environment.Dumb terminals and dumb storage devices were managed entirely by the brains inside the server.These machines were designed for Online Transaction Processing (OLTP), everywhere from bookingflights on airlines to handling financial transfers.
- The second era: Network-centric
In the 1980s and 1990s, dumb terminals were replaced with smarter workstations and personalcomputers; and dumb storage were replaced with smarter storage controllers. Local Area Networks (LANs)and Storage Area Networks (SANs) allowed more cooperative processing between users, servers andstorage. However, servers maintained their role as gatekeepers. Users had to go through aspecific server or server cluster to access the storage they had access to. These servers continuedtheir role in OLTP, but also manage informational databases, file sharing and web serving.
- The third era: Information-centric
Today, we are entering a third era. Servers are no longer the gatekeepers. Smart workstationsand personal computers are now supplemented with even more intelligent handheld devices, Blackberryand iPhones, for example. Storage is more intelligent too, with some being able to offer file sharingand web serving directly, without the need of an intervening server. The roles of servers have changed,from gatekeepers, to ones that focuses on crunching the numbers, and making information presentableand useful.
Sam Palmisano, CEO and chairman of IBM, first introduced this in March 2006 as the [Globally Integrated Enterprise],but the concept applies to organizations of all sizes, from large multi-nationals to the local [Mom and Pop shops].
Here is where Web 2.0 applications, digital media and archives fits in. These are focused on unstructured data that don't require relational database management systems. So long as the useris authorized, subscribed and/or has made the appropriate payment, she can access the information. With the appropriate schemes in place, information can now be mashed-up in a variety of ways, combined with other information that can render insights and help drive new innovations.
Of course, we will still have databases and online transaction processing to book our flights andtransfer our funds, but this new era brings in new requirements for information storage, and newarchitectures that help optimize this new approach.

So here we are in January, named after the two-faced Roman god Janus, who in their mythology was the god of gates and doors, and beginnings and endings.
-- Roger von Oech[Our "Janus-Like" Powers]
Well, it's 2008, which could mark the end to RAID5 and mark the beginnings of a new disk storagearchitecture. IBM starts the year with exciting news, acquiring new disk technology from a smallstart-up called XIV, led by former-EMCer Moshe Yanai. Moshe was ousted publicly in 2001 from hisposition as EMC's VP of engineering, and formed his own company. It didn't take long for EMC bloggersto poke fun at this already. Mark Twomey, in his StorageZilla blog, had mentioned XIV before back in August,[XIV], and again todayin [IBM Buys XIV].
The following is an excerpt from the [IBM Press Release]:
To address the new requirements associated with next generation digital content, IBM chose XIV and its NEXTRA™ architecture for its ability to scale dynamically, heal itself in the event of failure, and self-tune for optimum performance, all while eliminating the significant management burden typically associated with rapid growth environments. The architecture also is designed to automatically optimize resource utilization of all the components within the system, which can allow for easier management and configuration and improved performance and data availability.
"We are pleased to become a significant part of the IBM family, allowing for our unique storage architecture, our engineers and our storage industry experience to be part of IBM's overall storage business," said Moshe Yanai, chairman, XIV. "We believe the level of technological innovation achieved by our development team is unparalleled in the storage industry. Combining our storage architectural advancements with IBM's world-wide research, sales, service, manufacturing, and distribution capabilities will provide us with the ability to have these technologies tackle the emerging Web 2.0 technology needs and reach every corner of the world."
The NEXTRA architecture has been in production for more than two years, with more than four petabytes of capacity being used by customers today.
Current disk arrays were designed for online transaction processing (OLTP) databases. The focus was onusing fastest most expensive 10K and 15K RPM Fibre Channel drives, with clever caching algorithmsfor quick small updates of large relational databases. However, the world is changing, and peoplenow are looking for storage designed for digital media, archives, and other Web 2.0 applications.
One problem that NEXTRA architecture addresses is RAID rebuild. In a standard RAID5 6+P+S configuration of 146GB 10K RPM drives, the loss of one disk drive module (DDM) was recovered by reconstructing the data from parity of the other drives onto the spare drive. The process took46 minutes or longer, depending on how busy the system was doing other things. During this time,if a second drive in the same rank fails, all 876GB of data are lost. Double-drive failures are rare,but unpleasant when they happen, and hopefully you have a backup on tape to recover the data from.Moving to slower, less expensive SATA drives made this situation worse. The drives have highercapacity, but run at slower speeds. When a SATA drive fails in a RAID5 array, it could take severalhours to rebuild, and that is more time exposure for a second drive failure. A rebuild for a 750GBSATA drive would take five hours or more,with 4.5 TB of data at risk during the process if a second drive failure occurs.
The Nextra architecture doesn't use traditional RAID ranks or spare DDMs. Instead, data is carved up into 1MBobjects, and each object is stored on two physically-separate drives. In the event of a DDM loss, allthe data is readable from the second copies that are spread across hundreds of drives. New copies aremade on the empty disk space of the remaining system. This process can be done for a lost 750GB drive in under20 minutes. A double-drive failure would only lose those few objects that were on both drives, so perhaps1 to 2 percent of the total data stored on that logical volume.
Losing 1 to 2 percent of data might be devastating to a large relational database, as this could impactthe entire access to the internal structure. However, this box was designed for unstructuredcontent, like medical images, music, videos, Web pages, and other discrete files. In the event of a double-drivefailure, individual files would be recovered, such as with IBM Tivoli Storage Manager backup software.
IBM will continue to offer high-speed disk arrays like the IBM System Storage DS8000 and DS4800 for OLTP applications, and offer NEXTRA for this new surge in digital content of unstructured data. Recognizing this trend, diskdrive module manufacturers will phase out 10K RPM drives, and focus on 15K RPM for OLTP, and low-speedSATA for everything else.
Update: This blog post was focused on the version of XIV box available as of January 2008 that was built by XIV prior to the IBM acquisition. IBM has since made a major revision, made available August 2008 thataddresses a variety of workloads, including database, OLTP, email, as well as digital content and unstructuredfiles. Contact your IBM or IBM Business Partner for the latest details!
Bottom line, IBM continues to celebrate the new year, while the EMC folks in Hopkington, MA will continue to nurse their hangovers. Now that's a good way to start the new year!

Well, it's the last day of the year, and I will be celebrating the new year soon.In the mean time, I leave you with an interesting triple combo related to information.
- The Past
Nick Carr in his post [Cleaning the Slate] offers a list of articles he did not have time for in 2007.Of these, I enjoyed the 7-page keynote address[Information, Knowledge, Authority and Democracy] by Hunter R. Rawlings III.He talks about the importance of recorded knowledge, including discussions by the US founding fathers Thomas Jefferson and James Madison, and how information is an essential part of democracy.Here's a brief excerpt:
Following the burning of the Capitol in 1815,President James Madison restored the Library of Congress by purchasing ThomasJefferson’s library for the nation. It was Jefferson’s unique classification scheme that thefirst full-time Librarian of Congress, appointed by Madison, used in reorganizing theLibrary. The United States, embodied in the Congress, was to have the best library inthe world because knowledge was necessary to its fundamental purpose, the creationand protection of liberty.
James Madison believed, in other words, that he lived in a “knowledge age.” In ourmyopic way, we like to think that we invented the knowledge age sometime late in the20th century. We did not. Madison and his contemporaries had complete faith andconfidence in the necessity of what they called “useful knowledge,” which, of course,privileged many things we no longer consider useful, such as the ability to read Latinand Greek and to understand the lessons of ancient history.
- The Present
Tim Ferriss in his post [12 Filtering Tips for Better Information] discusses[Ryan Holiday] and his ["collaborative filtering"] suggestions on howto deal with the tidal wave of information that arrives at you every day. Thisincludes the use of an RSS feed reader, Stumble Upon, and del.icio.us websites. Here's an excerpt:
...by employing collaborative filtering, you use other people’s time to weed out the things that would waste yours. In fact, Del.icio.us and Stumble Upon polls your friends and people with similar interests for the most crucial sources of information and anything else you might have accident skipped over. If The Wisdom of Crowds has taught us anything, it is that a large group of people is drastically more efficient than you’ll ever be on your own.
Unless you enjoy grinding yourself to the bone, use this principle—whether you call it “crowdsourcing” or otherwise—to stop drinking from the information fire hose. It’s not more information, it’s better information, that distinguishes the real winners in business and life.
- The Future
Finally, Galacticast presents [A Copyright Carol],a humorous 5-minute parody video on what might happen in the future as a result of lawslike the Canadian Digital Millennium Copyright Act[DMCA].
Well, that's it for 2007, see you all next year!

Yesterday, I was able to get the "Build 650" up and running under Qemu emulation onmy Thinkpad laptop computer. Today, I was able to get my Thinkpad and my XO laptoptalking to each other for a "chat".
The built-in "Chat" activity is one of the many kid-friendly activities included onthe XO laptop for the One Laptop Per Child [OLPC] project.It is also possible for two or more people to share other activities, like editing a textdocument, or browsing the internet.
As they say, emulation is only 95% complete, and this is true in this case as well. My Thinkpaddoes not have a built-in video camera, and for some reason the Qemu emulation does not let mehear any sound, despite specifying "-soundhw es1370" parameter. And lastly, it doesn't have the"mesh network" built-in Wi-Fi capability, just standard 54Mbps 802.1g through my Linksys router.
So, I set both XO and Thinkpad to use the new "xochat.org" jabber server so that the two couldsee each other:
$ sugar_control_panel -s jabber xochat.org
I set my XO nickname to be "TonyP" and my Thinkpad to be "Pearson", and chose blue-orange forthe first, and orange-blue for the second.
The process of starting a chat is similar to other IM systems like IBM Lotus Sametime. You havea neighborhood view that shows all people online using the same jabber server. In my case therewere about 30 or so icons on the screen. From the colors on my XO, I was able to locate my Thinkpad,and invite him to a chat. You can share the chat with everyone on the network, or keep it privatebetween two people. I tried both ways to see the difference.
In a private two-way chat, the first person starts up their Chat activity, and sends an inviteto join to another person. The second person sees a flashing chat bubble on the bottom of thescreen to the left of all the other action bar icons. The difference is that the chat bubble isblue-orange matching the sender, rather than black-and-white of the rest of the icons.
If the recipient happens to be busy doing something else full-screen, like browsing the web, theredoesn't seem to be any interruption. It is only when he goes to "home view" will he see the coloredchat bubble and decide to join or not.
The chat itself colorizes the text to match to color of the participant's icons. Blue for one, and orangefor the other. It two people had identical color schemes I guess it might be hard to tell. Thetext is white, so it is best to choose darker colors for contrast.
A nice feature is that you can save your chat session with the "keep" button on the upper rightpart of the screen, and your dialogue discussion will show up as an entry in the "journal".
Using this technique, it is possible for someone who has one "XO" laptop and one regular computer,or two regular computers, to develop and test applications that involve the sharing aspect of educational opportunities. Chats can be between students, student-to-teacher, or event student-to-mentor.

Continuing my week's theme on the XO laptop from the One Laptop Per Child [OLPC
] foundation, I successfully managedto emulate my XO on another system.
Part of what is attractive of the XO laptop is the hardware, the high-resolution200dpi screen, the clever screen that rotates and folds flat into an eBook reader,and the water-tight, dust-proof keyboard. The other part is the software, howthey managed to pack an entire operating system, with useful applications, intoa 1GB NAND flash drive.
The drawback for developers like me is the risk of changing something that breaks the system. For example, my first attempt to create my own activityresulted in a blank space in my action bar, and my journal went into someinfinite loop, blinking as if it were still loading for minutes on end. I fixed it by deleting out the activity I created and rebooting.
To get around this, I successfully ran the disk-image under Linux's Virtual Machinesoftware called Qemu. This is an open source offering, with a proprietary add-onaccelerator called Kqemu. Here were the steps involved:
- Base Operating System
Qemu is now available to run on Linux, Windows and OS X-Intel. I have an Ubuntu 7.04"Feisty Faun" version of Linux installed on my system from a project I did last year, so decided to use that.
Normally, "apt-get install qemu" would be enough, but I wanted to get the latest release, so I downloaded the [0.9.0 version]tarball of compiled binaries. Note that trying to compile Qemu from source requiresa downlevel gcc-3.x compiler, and my attempts to do this failed. The compiled binariesworked fine.
The Kqemu author hasn't packaged this for distribution, so I download the source code anddid my own compiles. You can do the "configure-make-install" using the regular gcc 4.1compiler and it went smoothly.
Getting Kqemu active was bit of a challenge. I had to make sense of Nando Florestan's[Installing Kqumu in Ubuntu] article,and the subsequent comments that followed.
There is a tiny [8MB Linux image]that should be used to verify the Kqemu is activated correctly.
- The Disk Image
As with other development efforts, there are the older stable versions, and the bleedingedge development versions. I chose the 650 Build from the [Ship.2 stable versions], whichmatches the version on my XO laptop. The image comes as a *.bz2, which is a highly-compressedfile. Using "Bunzip2", the 221MB file expands to something like 932MB.
I renamed the resulting file to "build650.img"
Once I got all this done, I then made a simple script "launch" in my /home/tpearson/bin directory:
#!/bin/shqemu -m 256 -full-screen -kernel-kqemu -soundhw es1370 -net nic,model=rtl8139 -net user -hda $1
Then "launch build650.img" was all I needed to run the emulation. The full-screen mode helpsemulate the view on XO laptop. I was able to change the jabber server to "xochat.org" and see otherXO laptops online on my neighborhood view.
When running under Qemu, you can't just press Ctrl-Alt-something. For example, Ctrl-Alt-Erase onthe XO reboots the Sugar interface. However, do this on a Linux system, and it reboots your nativeX interface, blowing away everything.Instead, you press Ctrl-Alt-2 to get to the Qemu console, designated by (qemu) prompt,and then type:
Press "Ctrl-Alt-1" followed by "Ctrl-Alt" to get back to the emulated XO screen.
With this emulation, I am more likely to try new things, change files around, edit system files,and so on, without worrying about rendering my actual XO laptop unusable. Once debugged, I canthen work on moving them over to my XO, one at a time.

Wrapping up this week's theme on the XO laptop, I decided to take on thechallenge of printing. I managed to print from my XO laptop to my laserjet printer.I checked the One Laptop Per Child [OLPC
] website,and found there is no built-in support for printers, but there have been several peopleasking how to print from the XO, so here are the steps I did to make it happen.
(Note: I did all of these steps successfully on my Qemu-emulated system first, and then performed them on my XO laptop)
- Step 1: Determine if you have an acceptable printer
The XO laptop can only connect to a printer via USB cable or over the network.Check your printer to see if it supports either of these two options. In my case, my printer is connected to my Linksys hub that offers Wi-Fi in my home.
The XO runs a modified version of Red Hat's Fedora 7, so we need to also determineif the printer is supported on Linux.Check the [Open Printing Database]for the level of support. This database has come up with the following ranking system.Printers are categorized according to how well they work under Linux and Unix. The ratings do not pertain to whether or not the printer will be auto-recognized or auto-configured, but merely to the highest level of functionality achieved.
- Perfectly - everything the printer can do is working also under Linux
- Mostly - work almost perfectly - funny enhanced resolution modes may be missing, or the color is a bit off, but nothing that would make the printouts not useful
- Partially - mostly don't work; you may be able to print only in black and white on a color printer, or the printouts look horrible
- Paperweight - These printers don't work at all. They may work in the future, but don't count on it
If your printer only supports a parallel cable connection, or does not have a high enough ranking above, go buy another printer. The [Linux Foundation] websiteoffers a list of suggested printers and tutorials.
In my case, I have a Brother HL5250-DN black-and-white laserjet printer connected over a network to Windows XP, OS X and my other Linux systems. It is rated as supporting Linux perfectly, so I decided to use this for my XO laptop.
- Step 2: Install Common UNIX Printing System (CUPS)
Technically, Linux is not UNIX, but for our purposes, close enough. Start the Terminalactivity, use "su" to change to root, and then use "yum" to install CUPS. Yum will automatically determine what other packages are needed, in this case paps and tmpwatch. Once installed, use "/usr/sbin/cupsd" to get the CUPS daemon started, and add this to the end ofrc.local so that it gets started every time you reboot.

[olpc@xo-10-CC-6F ~]$ subash-3.2# yum install cups...Total download size = 3.0 MIs this OK [y/N]? y
bash-3.2# /usr/sbin/cupsdbash-3.2# echo "/usr/sbin/cupsd" >> /etc/rc.d/rc.localbash-3.2# exit[olpc@xo-10-CC-6F ~]$
- Step 3: Install Opera or Firefox browser
To download the appropriate drivers, you may need a browser that can handle file downloads. I have triedto do this with the built-in Browse activity (aka Gecko) but encountered problems. I have both Opera and Firefox installed, but I will focus on Opera for this effort.I also installed the older18.104.22.168 version of the Flash player (worked better than the latest 22.214.171.124 version) and Java JRE.Follow the OLPC Wiki instructions for [Opera, Adobe Flash,and Sun Java] installation, thenverify with the following [Java and Flash] testers.
- Step 4: Download drivers and packages unique for your printer
In my case, I used Opera to get to the [Brother Linux Driver Homepage], and downloaded the RPM's for LPR and CUPS wrapper. These are the ones listed under "Drivers for Red Hat, Mandrake (Mandriva), SuSE". I saved these under "/home/olpc" directory.
[olpc@xo-10-CC-6F ~]$ subash-3.2# cd /home/olpcbash-3.2# rpm -vi brhl5250dnlpr-2.0.1-1.i386.rpmbash-3.2# rpm -vi cupswrapperHL5250DN-2.0.1-1.i386.rpmbash-3.2# exit[olpc@xo-10-CC-6F ~]$
- Step 5: Create a "root" password
By default, the root user has no password. However, you will need it to be something for later steps,so here is the process to create a root password. I set mine to "tony" which normallywould be considered too simple a password, but ignore those messages and continue.We will remove it in step 8 (below) to put things back to normal.
[olpc@xo-10-CC-6F ~]$ subash-3.2# passwdChanging password for user root.New UNIX password: tonyBAD PASSWORD: it is too shortRetype new UNIX password: tonypasswd: all authentication tokens updated successfullybash-3.2# exit[olpc@xo-10-CC-6F ~]$
- Step 6: Launch CUPS administration
Here I followed the instructions in Robert Spotswood's [Printing In Linux with CUPS] tutorial.Launch the Opera browser, and enter "http://localhost:631/admin" as the URL. The localhostrefers to the laptop itself, and 631 is the special port that CUPS listens to from browsers. You can alsouse 127.0.0.1 as a shortcut for "localhost", and can be used interchangeably.
In my case, it detected both of my networked printers, so I selected the HL5250DN, entered thelocation of my PPD file "/usr/share/cups/model/HL5250DN.ppd" that was created in Step 4. I set the URI to "lpd://192.168.0.75/binary_p1" per the instructions [Network Setting in CUPS based Linux system] in the Brother FAQ page. I chage the page size from "A4" to "Letter".I set this printer as the default printer. When it asks for userid and password, that is whereyou would enter "root" for the user, and "tony" or whatever you decided to set your root password to.
Select "Print a Test Page" to verify that everything is working.
- Step 7: Printing actual files
Sadly, I don't know Opera well enough to know how to print from there. So, I went over to my trustedFirefox browser. Select File->Page Setup to specify the settings, File->Print Preview tosee what it will look like, and then File->Print to send it to the printer.
To print the file "out.txt" that is in your /home/olpc directory, for example, enter"file:///home/olpc/out.txt" as the URL of the firefox browser. This will show the file,which you can then print to your printer. I had to specify 200% scaling otherwise the fontswere too small to read.
- Step 8: Remove the "root" password
If you want to remove the root password, here are the steps.
[olpc@xo-10-CC-6F ~]$ suPassword: tonybash-3.2# passwd -d rootRemoving password for user root.passwd: Successbash-3.2# exit[olpc@xo-10-CC-6F ~]$
Now the problem is that there is no way to print stuff from any of the Sugar activities. The best place toput in print support would be the Journal
activity. Along the bottom where the mounted USB keys arelocated could be an icon for a printer, and dragging a file down to the printer ojbect could cause it tobe send to the printer.
The alternative is to write some scripts invocable from the Terminal activity to determine what isin the journal, and send them to LPR with the appropriate parameters.
I did not have time to do either of these, but perhaps someone out there can take on that as a project.

Continuing my week's theme on the XO laptop from the One Laptop Per Child [OLPC
] project, I have been amused watching the OLPC forum discussion on the choiceof browser options available.
- Built-in Browser
The built-in browser is simple but functional. It is full screen,with back, forward, and bookmark buttons, and an entry field forthe URL. This browser is fully integrated with the Sugar platform,files downloaded will appear in the journal. Download an Activity*.xo file, for example, and you can install it from the Journal.If you want to upload a file, click BROWSE on the website, and theJournal will pop up to choose files from.
Out of the box, the XO supports a minimal Flash that can handlesome Flash-based games but not YouTube videos, and does not supportJava.
The good folks of Opera have built a special edition for the XO laptop.However, some settings need to be changed to make the fonts large enoughto read.
Opera can be run as a Sugar activity, but this just launches a mothertask, which in turn launches a daughter task that actually runs thebrowser. This means that Home View will have two icons. The mothertask has an the Opera icon, but click on it and you get a grey screen.The daughter task appears as a grey circle, click on it and you get thebrowser screen. Alt-Tab will rotate through the Activities, so thegrey screen of the mother task is part of the rotation.
Although Opera has one foot on the Sugar platform, and one foot off,the lack of integration means poor interaction with the journal. The use of Opera is correctly registered. However, downloadingfiles requires a working knowledge of subdirectories, and uploading anythingrequires knowing what it is called, and where it is located. Not obviousfor many of the items created by Sugar applications.
The XO laptop is based on Redhat Fedora distribution, so I downloadedthe Firefox RPM package and installed this. To run, you need to startthe Terminal Activity, and then at the cursor type firefox.Journal only registers that the Terminal activity was used, but not anythingelse.
Since I run Firefox 2.0 on Windows XP, OS X and Linux, I am very familiarwith this browser, and it works as expected. Like Opera, there are shortcut keys, tabs for multiple pages, and optionsto add Java and Flash player. I was able to install add-onsfor Del.icio.us and FireFTP, and they worked as expected. Having accessto FTP sites will make development on the XO much easier.Again all files are uploaded/downloaded to directories, so some workingknowledge of where files are placed is required.
The fonts in Firefox did not expand/shrink as nicely as they had in Opera.Be careful not to select "View->
To close, you have to select File->Quit from the browser window, whichbrings you back to the Terminal activity, which you can then shutdown with Ctrl-Esc.
For now, I will keep all three and continue to evaluate them.I saw a few opportunities for improvement:
- The Opera and Terminal icons are not on the first screen.You have to hit the right arrow to get to the "overflow" set of icons. Re-ordering the icons is simply a matter of editing the following file with "vi"(my first few lines I use are shown below):
Put the activities in the order you want. Any activity not listed willappear after these.
- It might be possible to create a modified Terminal activity thatinvoked Firefox directly, to eliminate having to type it in each time.
- Several people have expressed interest in a browser that runs entirely withthe Xo laptop folded over in eBook/Game mode, such that thekeyboard is completely covered up, exposing only the up-left-right-down arrowsand the Circle/Square/X/Check buttons.
- Change the "News Reader" to invoke Bloglines instead. This might be yetanother modified Terminal activity, but borrow the icon from News.

|Tony Pearson holding his new XO laptop|
My XO laptop arrived Friday, December 21, this was from the [Give 1 Get 1 (G1G1)] program fromthe One Laptop Per Child (OLPC) foundation. The program continuesto the end of this month (December 31).
Here are my first impressions.
- Setup was Easy
Open the box, put in battery, and plug in the adapter. Enter your name and choose your favorite color for your stick figurine. No passwords, no parameters. Software is pre-installed and ready to use.
The four pages of instructions included how to open the unit (not intuitive), where the various connection ports are located, what the home screen and neighborhood screen look like, safety warnings, and a nice letter from Nicholas Negroponte with an 800 phone number and website in case more help is needed.
Connecting to the internet was the first thing I did. The neighborhood screen shows all the Wi-Fi access points. It recognized mineand three others. I clicked on mine, entered my WEP key, and was connected.
- Main Screen
This is a Linux operating system running the Sugar user interface.There are four screens:
- Neighborhood - shows all Wi-Fi access points
- Friends - shows all other XO laptops nearby, in my case I am all alone
- Home - your stick figurine with all the applications you can choose from are represented as icons at the bottom, just like OS X on my Mac Mini, or the launchpad on my Windows XP. Left panel for clipboard items.
- Application - Applications run in full-screen mode
Four buttons across the top allow you to jump to any screen instantly.Everything else is single left-click. No double-clicks or right-clicks.
A circle on the home screen designates which applications are running, and how much of the available 256MB RAM they are consuming. This makes it easy to seeif you can run more applications or need to shut something down. Youcan jump to any application, or shut it down, from this view.
Shutting down the XO is done by clicking your stick figurine,and choosing shutdown.
- Pre-installed Applications
I fired up the browser. The default 'home page' offers some help offline, as well as links to online resources and a google search bar. The full-color 1200x900 is very easy to read. You can hit ctrl+plus to make the fonts bigger. In bright sunlight, the screen turns automatically to greyscale.The built-in browser is easy enough to use, with standard back, forward, re-load, and bookmark buttons. The URL entry field also shows the pages title. It doesn't have tabs to see multiple pages at the same time, but I was able to fire up a second instance of the browser, so thatI could alt-tab back and forth between the two web sites.
There are so many applications that they don't all fit on the bottom of the screen.Left and right tab buttons will display the next set. I don't know if it is possible to re-order the icons, but I can certainly see some applications appealing to different ages, and perhaps re-ordering them into age-specific groups might be helpful.
Basic applications include the Abiword word processor, a PDF viewer, a simple paint program, calculator, chat, and news RSS feed reader; TamTam music to play and edit compositions; and some learn-to-program-a-computer software including Pippy, Etoys, and TurtleArt.
The 'record' program lets you take 640x480 pictures with the built-in camera, up to 45 seconds of video and audio recording. The picture abovewas taken with my XO, and edited online using [snipshot.com]. Another program can be usedto make video calls to another computer, similar to Skype or IBM Lotus Sametime.
- Connection ports
The XO has built-in microphone and speakers, but also microphone and speaker ports, as well as three USB ports, and a slot for an SD memory card.
The QWERTY keyboard is designed for small children hands, I found myself using my two index fingers in a hunt-and-peck style. People who use Blackberry's or other hand-held devices might be able to use their two thumbs instead. Also, I am not used to a touchpad as the pointing device. My other laptops have a red knob between the G/H/B keys that acts like a joystick. So, I decided to attach my Apple keyboard/mouse to one USB port, which allows me faster typing and better resolution with my mouse.
I also inserted a 1GB SD card into the slot. Getting to the SD slot was challenging--you have to rotate the screen 90 degrees so that the lower right corner is over the laptop handle. It appears I need to purchase some tweasers to get my SD card back out, so until then, it will remain there as permanent addition to my XO.
A terminal application provides a command line interface into Linux.
[olpc@xo-10-CC-6F ~] $ df -hFilesystem Size Used Avail Use% Mounted on mtd0 1.0G 365M 660M 36% /tmpfs 35M 0M 35M 0% /dev/shm/dev/mmcblk0p1 983M 7.9M 975M 1% /media/CANON_DCThe 'vi' editor is installed, in case I need to make changes to fstab or anythingelse in my /etc directory.
There is no S-video or VGA port. However, a teacher could probably fold thislaptop up in e-book mode and lay it flat on an [overhead projector] since the screen can handle bright sunlight in black-and-white mode.
- The Journal and the Clipboard
There are no folders or subdirectories here. The journal acts as your desktop, holding all the files you have referenced, sorted in chronological order with the most recent on top. The journal application is started automatically when you boot up.My SD card is shown as a separate entry at the bottom right corner, but I have access only to files on my top-level directory on the card. The journal allows you to drag and drop between the system and the SD flash card.The list can be filtered by file type and application, so finding things is easy.You can also copy anything in the journal to the clipboard, appearing on the leftpanel of the home screen. You can then launch or paste this into other applications.
Pressing Alt-1 takes a 1200x900 snapshot of the current screen, and puts it into the journal.On websites that allow you to upload a file, including GMAIL, snipshot.com, etc. the browse button brings up the journal. So, for example, you could take a snapshot of the current webpage or paint creation, and send it as an attachment to someone via GMAIL. Google has an XO-enabled version of GMAIL that you can download from the OLPC activities page.
This entire post, including the picture above, was done with the XO laptop itself. I am impressed with the thought that went into this design, and I see great potential here. The interface adequately hides the Linux operating system for those who just want to use the computer, but makes it readily accessible for those who want to learn more about the Linux operating system and computer programming.

Well, tomorrow is the Winter solstice, at least for those of us in the Northern hemisphere of the planet.As often happens, I have more vacation days left than I can physically take before they evaporateat the end of the year, so next week I will be off, going to see movies like the new["Golden Compass"
]or perhaps read the latest book from [Richard Dawkins
Next week, I suspect some of the kids on my block will be playing with radio-controlled cars orplanes. If you are not familiar with these, here's a [video on BoingBoing]that shows Carl Rankin's flying machines that he made out of household materials.
Which brings me to the thought of scalability. For the most part, the physics involvedwith cars, planes, trains or sailboats apply at the toy-size level as well as the real-world level. One human operator can drive/manage/sail one vehicle. While I have seen a chess master play seven opponents on seven chess boards concurrently, itwould be difficult for a single person to fly seven radio-controlled airplanes at the same time.
How can this concept be extended to IT administrators in the data center? They have to deal withhundreds of applications running on thousands of distributed servers.In a whitepaper titled [Single System Image (SSI)], the threeauthors write:
A single system image (SSI) is the property of a systemthat hides the heterogeneous and distributed nature of theavailable resources and presents them to users and applicationsas a single unified computing resource.
IBM has some offerings that can help towards this goal.
- Server clusters
Even in the case where yourvehicle is being pulled by eight horses--(or eight reindeer?)--a single operator can manage it, holding the reins in both hands. In the same manner,IBM has spent a lot of investment and research into supercomputers, where hundreds of individualservers all work together towards a common task. The operator submits a math problem, for example,and the "system system image" takes care of the rest, dividing the work up into smaller chunksthat are executed on each machine.
When done with IBM mainframes, it is called a Parallel Sysplex. The world's largest business workloadsare processed by mainframes, and connecting several together and working in concert makes this possible.In this case, the tasks are typically just single transactions, no need to divide them up further, justbalance the workload across the various machines, with shared access to a common database and storageinfrastructure so they can all do the work equally.
Last August, in my post [Fundamental Changes for Green Data Centers], I mentioned that IBM consolidated 3900 Intel-based servers onto 33 mainframes. This not only saves lots of electricity, but makes it much easier for the IT administratorsto manage the environment.
- Storage virtualization
Parallel Sysplex configurations often require thousands of disk volumes, which would have been quitea headache dealing with them individually. With DFSMS, IBM was able to create "storage groups" wherea few groups held the data. You might have reasons to separate some data from others, put them inseparate groups. An IT administrator could handle a handful of storage groups much easier than thousandsof disk volumes. As businesses grow, there would be more data in each storage group, but the numberof storage groups remains flat, so an IT administrator could manage the growth easily.
IBM System Storage SAN Volume Controller (SVC) is able to accomplish this for other distributed systems.All of the physical disk space assigned to an SVC cluster is placed into a handful of "managed diskgroups". As the system grows in capacity, more space is added to each managed disk group, but few IT administrators can continue to manage this easily.
The new IBM System Storage Virtual File Manager (VFM) is able to aggregate file systems into one globalname space, again simplifying heterogeneous resources into a single system image. End users have a singledrive letter or mount point to deal with, rather than many to connect to all the disparate systems.
- Centralized Administration
Lastly we get to the actual management aspect of it all. Wouldn't it be nice if your entire data centercould be managed by a hand-held device with two joysticks and a couple of buttons? We're not quite there yet, but last October we announced the [IBM System Storage Productivity Center (SSPC)]. This is a master consolethat has a variety of software pre-installed to manage your IBM and non-IBM storage hardware, includingSAN fabric gear, disk arrays and even tape libraries. It lets the storage admin see the entire data centeras a single system image, displaying the topology in graphical view that can be drilled down using semanticzooming to look at or manage a particular device or component.
Customers are growing their storage capacity on average 60 percent per year. They could do this by havingmore and more things to deal with, and gripe about the complexity, or they can try to grow theirsingle system image bigger, with interfaces and technologies that allow the existing IT staff to manage.

As we wrap up the year, people's thoughts turn to archive anddata retention.
The [Robert Frances Group] have put out a research paper titled Optimizing Data Retention and Archiving - November 2007 that helps IT executives understand the cost differences for a disk-only archive approach versus disk/tape archive approach and how an [IBM System Storage DR550] offering can help address the long-term storage archive requirements with a world-class storage strategy that reduces cost, improves efficiency and supports compliance. Here is an excerpt:
Ongoing legal, audit, and regulatory requirementswill continue to drive IT groups to improvearchive policies, processes, strategy, andefficiency. The choice of which technologies touse will have a profound impact on the success ofsuch efforts, since technologies like the DR550embody many aspects of the strategy, processes,and policies that must be decided upon. When itcomes to tape, IBM's DR550 is unique inproviding that support. Competitors tout disk-onlysolutions as the wave of the future, but researchindicates otherwise. The most basic benefits arecost and mobility, and despite the various vendorproclamations to the contrary, tape is still only afraction of the cost of disk and will remain so inthe foreseeable future.
This paper is yet another nail in the coffin of EMC Centera.In his post [Anyone Naughty on Your List…], Jon W Toigo points to an eBay fire sale of an EMC Centera Gen 4.
There has never been a better time to switch from EMC Centera to theIBM System Storage DR550.

Last week, EMC put out its press release[EMC Advances SAN Virtualization Capabilities with New Version of EMC Invista
], and fellowIBM blogger BarryW does a great job reviewing the reaction from the media, in hispost [Deja-vu - Invista 2 - again?!"
]. A few questions have popped up from my colleagues, so I thoughtI would take a stab at them here.
- Why now?
This is a reasonable question. Since Invista 2.0 came out months ago in August, and Invista 2.1 is rumored to be out by end of this month, why put out a press release now, rather than just wait a few weeks? Thesignificant part of this announcement was that EMC finally has their first customer reference.To be fair, getting a customer to agree to be a reference is difficult for any vendor. Some non-profitsand government agencies have rules against it, and some corporations just don't want to be bothered byjournalists, or take phone calls from other prospective customers. I suspect EMC wanted to put the good folks from Purdue University in front of the cameras and microphones before they:
- suffer an outage,
- change their minds, and/or
- leave for Winter break
It takes a while for new technologies to get adopted by the marketplace. Geoffrey Moore wrote a book titled [Crossing the Chasm: Marketing and Selling Disruptive Products to Mainstream Customers] that I highly recommend. If you don'thave time to read the entire book, here is a quick [11-page summary] from Parkerhill Technology Group.
In Moore's terminology, Purdue University would be a "technology enthusiast", interested in exploring the technologyof the EMC Invista. Universities by their very nature often see themselves as early adopters, willing to take big risks in hopes to reap big rewards. The chasm happens later, when there are a lot of early adopters, all willing to be reference accounts. The mainstream market--shown here as pragmatists, conservatives, and skeptics-- are unwillingto accept reference claims from early adopters, searching instead for moderate gains from minimal risks. They prefer references from customers that are similar in size and industry. Whether a vendor can get a product to cross this chasm is the focus of the book.
- Why "SAN" virtualization?
Technically, Invista is "storage" virtualization, not "SAN" virtualization. Virtualizationis any technology that makes one set of resources look and feel like a different setof resources, preferably with more desirable characteristics. You can virtualizeservers, SANs, and storage resources.
Here's a quote from Cisco's whitepaper called [Storage Virtualization a Work in Progress]
Virtual SAN (VSAN) technology, supported bythe Cisco MDS 9500 Series Multilayer Director Switch, partitions a single physical SAN into multipleVSANs, allowing different business functions and requirements to share a common physical infrastructure.
How does Invista advance Cisco's VSAN functionality? It doesn't, but that doesn't makethe title a falsehood, or the press release by association full of lies.If you read the entire press release, EMCcorrectly states that Invista is "storage" virtualization. Some storagevirtualization products, like EMC Invista and IBM System Storage SAN Volume Controller (SVC), require a SAN as a platform for which to perform their magic.Marketing people might use the term "SAN" torefer not just the network gear that provides the plumbing, but also to include the storage devices that are attached to the SAN. In that light, theuse of "SAN virtualization" can be understood in the title.
More importantly, it appears that EMC no longer requires that you purchase new SAN equipment from themwith Invista. When the Invista first came out, it cost over a quarter-million US dollars to cover thecost of the intelligent switches, but with the price drop to $100K, I imagine this means theyassume everyone has an appropriately-supported intelligent switch already deployed.
- Why this architecture?
In his post [Storage Virtualization and Invista 2.0], EMC blogger ChuckH does a fair job explaining why EMC went in this direction for Invista, and how it is different thanother storage virtualization products.
Most storage virtualization products are cache-based. The world's first disk storagevirtualization product, the IBM 3850 Mass Storage System, introduced in 1974, and thefirst tape virtualization product, the IBM 3494 Virtual tape Server, introduced in 1997, bothused disk cache in front of tape storage. Later virtualization products, like IBM SVC and HDS USP-V, use DRAM memory cache in front of disk storage, but the concept is the same.People are comfortable with cache-based solutions, because the technology is matureand well proven in the marketplace, and excited and delighted that these can offer the following features in a mixed heterogeneous disk environment:
- improved performance
- instantaneous point-in-time copy
- synchronous mirroring
- asynchronous mirroring
None of these features are provided by Invista, as there is no cache in the switch. Instead,Invista is a "packet cracker"; it cracks open each FCP packet, inspects and modifies the contents, then passes theFCP packet along to the appropriate storage device. This process slows down each read andwrite by some amount, perhaps 20 microseconds. The disadvantage of slowing down every readand write is offset by having other benefits, like non-disruptive data migration.
To compensate for Invista's inability to provide these features,EMC offers a second solution called EMC RecoverPoint, which is an in-band cache-based appliancesimilar in design to SVC, but maps all virtual disks one-to-one to physical disks. It offersremote distance asynchronous mirroring between heterogeneous devices.EMC supports RecoverPoint in front of Invista, but if you are considering buying bothto get the combined set of features, you might as well buy an IBM SVC or HDS USP-V instead,in one system, rather than two, which is much less complicated. IBM SVC and HDS USP-Vhave both "crossed the chasm" having sold thousands of units to every type and size of customer.
Hopefully, this answers the questions you might have about EMC Invista.

Some upcoming books have caught my attention.
Last year, I covered Chris Anderson's book [The Long Tail]. This year, Chris Anderson, editor-in-chief of Wired.com, has an upcoming book titled Free, the past and future of a radical price. Chris talked about his book here at Nokia World 2007 conference, and the [46-minute video] is worth watching.He asks the big question "What if certain resources were free?" This could be electricity, bandwidth, or storage capacity. He explores how this changes the world, and createsopportunities for new business models. However, many people are stuck in a "scarcity" modeland treat nearly-free resources as expensive, and find themselves doing traditional things thatdon't work anymore. Chris mentions [Second Life] as aneconomy where many resources are free, and seeing how people respond to that.Rather than focusing on making money, new businesses are focused on gainingattention and building their reputation. Here are some example business models:
- Cross-subsidy: give away the razors, sell the razor blades; or give away cell phones and sell minutes
- Ad-Supported: magazines and newspapers sell for less than production costs
- Freemium: 99% use the free version, but a handful pay extra for something more
- Digital economics: give away digital music to promote concert tours
- Free-sample marketing: give away samples to get word-of-mouth advertising
- Gift economy: give people an opportunity and platform to contribute like Wikipedia
Nick Carr writes a post [Dominating the Cloud], indicatingthat IBM, Google, Microsoft, Yahoo and Amazon are the five computing giants to watch, as they are more efficient atconverting electricity into computing than anyone else. Last month, I mentioned IBM and Google partnership on cloud computing in my post[Innovationthat matters: cell phones and cloud computing].Nick's upcoming book titled[The Big Switch] looks into "Utility Computing",comparing the change of companies generating their own electricity to using an electric grid, to the recent developments of cloud computing and software as a service (SaaS). Amazon's latest "SimpleDB" online databaseis cited as an example.
Last, but not least, Seth Godin writes in his post [Meatballs and Permeability] about the bits-vs-atoms issue, what Chris Anderson above refers to as the new digital economy. The idea here is that value carried electronically as bits (digital documents, for example) have completely different economics than value carried as atoms (physical objects), andrequires new marketing techniques. Methods from traditional marketing will not be effective in this new age.Here is a [review] of Seth's new book Meatball Sundae: Is Your Marketing Out of Sync?
All three of these books seem to be covering the same phenomenon, just from different viewpoints. I lookforward to reading them.

Web Worker Daily has an article[Bill Gates on Collaboration and Continued Learning
] discussing Bill Gates' essay [The skills you need to succeed
].Bill talks about the importance of software, and how it has turned nearly everyone into information workers.
While Bill Gates is personally benefiting from code he wrote 30 years ago, most software engineers don't getroyalties for their creative efforts. Robin Harris on StorageMojo has a great piece on [Why are the writers striking?]The writers in this case are those who write scripts for television programs. They get 4 cents for every$19.99 DVD sold today, and want this bumped up to 8 cents. More importantly, they want the same deal forcontent shown over the internet. Currently, they get nothing when content they wrote for is shown on the internet, and they would like that fixed also.
Paying royalties to creative writers encourages them to write good stuff. The best stuff will result in moreroyalties, and we want to encourage this. What about software engineers? Don't we want them to write the beststuff also? Shouldn't they get royalties too, not just a flat salary and continued employment?
Something to think about...

Well it's Friday and I'm wrapping up my week here in California, at the Almaden Research Center.The weather has been slightly milder than what we have back in Tucson.
This is my final installment of my 3-part series covering the IBM Systems Journal's [fifteen articles about IBM Service Management].You can go back and read the earlier parts of this series[Part 1,Part 2].
- From a technology-oriented to a service-oriented approach to IT management
Companies are challenged with shifting from a technology/resource-oriented to a service-oriented approach to IT management. This involves new processes, a new reportingstructure for the IT staff, new tools and technologies, and new data to be captured.A top-down approach is recommended for large organizations, but a bottom-up approachmight be easier to implement for small and medium sized businesses.
- IT service management architecture and autonomic computing
IBM has been promoting the concept of Autonomic Computing since 2001. A self-managed resource can have an autonomic manager with sensor and effector. The sensor is used to monitor status, a knowledge basecan analyze and plan for appropriate modifications, and execute these through theeffector. The Autonomic Computing Reference Architecture (ACRA) aligns with the Information Technology Service Management (ITSM) model well, with the CMDB acting asthe knowledge base for the autonomic managers. See my earlier post[Self tuning guitars and storage].
- Evolving standards for IT service management
Changes to the IT infrastructure must be closely managed to avoid disruptions.IT organizations recognize that standards-based solutions enable interoperability,with less risk, to connect internal and external applications. Standards can be formally developed by standards bodies like ISO, IETF, W3C, OASIS, and DMTF; or be de facto standards that become widely used by companies, which can then laterbe adopted by standards bodies. SML and SDD are emerging standards that are incompatible with the current set of Web Services-based protocols, like WSDM, but work isunderway to try to determine a unifying standard to support all of these under ITSM.
- Prospects for simplifying ITSM-based management through self-managing resources
An ideal computing system would take over a great deal of its own management.Today's IT systems are brittle, difficult to understand, and dangerous to change.The savings from automating some tasks are dwarfed by the irreducible costs of humandecision making, agreements and approvals built in formal processes. A true self-managing, scalable IT system would consist of a number of nearly-identical boxes,with a web interface to define high-level policies and provide information on utilization and performance. As the system needs to expand, it can automatically place the order. When the new boxes arrive, they are placed and connectedinto the data center, and the system configures and provisions them appropriately.
- IT Autopilot: A flexible IT service management and deliver platform for smalland medium business
Using an airplane analogy, the pilot performs manual steps to get the plane safelyoff the ground, then turns it over to the autopilot for normal operations. The ITAutopilot intends to do this for IT service management in small and medium business (SMB)that may not have a large dedicated IT staff, using an SOA approach that isloosely coupled, stateless, and adhering to Web Services standards. The IT Autopilotemploys workflow-based controls, the autonomic computing MAPE model, and customizedpolicies to address SMB requirements. It could be deployed as an appliance, similarto IBM System Storage Productivity Center.

I'm continuing my coverage of IBM Systems Journal's [fifteen articles about IBM Service Management
].As storage hardware cost per GB declines 25 percent per year, the cost of labor has grown to nearly 70percent of the total IT budget. This brings new focus on how we do things, rather than what things siton the raised floor. Yesterday, my post summarized[the first five articles
].Here is what I got out of the next five articles:
- Integrated change and configuration management
IT Infrastructure Library (ITIL) best practice covers a variety of disciplines, including incident management,problem management, release management, service help desk, change management, and configuration management.IBM has combined the last two into a single database, and this paper provides insights gained fromimplementing these in practice. A special section talks about how service providers can support multipleclients that must be kept separate from each other.
- The process of building a Process Manager: Architecture and design patterns
Business processes coordinate and sequence the work done by a collection of people.Most companies define their business process from scratch, and develop their own applicationsto support their implementation. Process Managers are "out of the box" applications that help customers integrateand automate more quickly than building from scratch. These Process Managers leverage and update informationabout configuration items (CIs) in the configuration management database (CMDB). One of the first developedby IBM was the IBM Tivoli Storage Process Manager.
- Integration of domain-specific IT processes and tools in IBM Service Management
ITIL tells you what needs to get done, but it doesn't tell you exactly how to do it. Completing a simplechange request to the IT environment can have a drastic impact on service level agreements (SLAs), utilization of existing storage capacity, and business operations. Sometimes it is important to use multipleProcess Manager applications together. To accomplish this, it is important to launch and land in contextat the appropriate points for smooth transition.
- Using a model-driven transformational approach and service-oriented architecture for service deliver management
Companies are considering outsourcing as a way to focus on core competencies. However, the trend is towardselective outsourcing, where the customer controls the IT solution architecture and retains their legacy tools.As a result, service providers inherit the business and IT processes from their clients. IBM Research has developed the model-driven business transformation (MDBT) method that choreographs workflow tools with humanactivities. A "balanced scorecard" allows both client and outsourcer monitor progress towards strategic goals.
- Catalog-based service request management
Service providers (outsourcers) are able to bring the latest IT technology, best practices, and skilledservice delivery teams. Unfortunately, unique business processes from each client limits the ability to leveragethese resources effectively. A service delivery management platform (SDMP) catalog serves as a repositoryof atomic services and the delivery teams that can perform them. This allows outsourcers to leverage resourcesacross multiple clients, while still being able to tailor business compositions of these atomic services to an individual client's requirements.

The latest IBM Systems Journal has [fifteen articles about IBM Service Management
], which includes the disciplines for managing storage resources as part of an overall IT data center.As with most journals, these articles are heavy academic efforts, not light summer reading.
However, since I have moved from marketing to consulting, I need to read these kinds of articles to keep up with the industry. I realize many people don't have time to read allof these, so over the next three days, I will give some quick highlights in hopefully more understandablelanguage. Here is what I got out of the first five articles:
- An Overview of IBM Service Management
This 10-page article provides a good overview of what the other articles go into greater detail.The role of information has changed, from supporting back-office tasks like payroll andinventory, to enabling growth in the business itself, providing insight and competitive advantage. The challenges are summarized under "Four C's": Complexity, Change, Cost, and Compliance. The recommended approach is to engage with IBM,who has thousands of practitioners with years of experience in ITIL, eTOM, COBIT, CMMI and SOA.
- Adding value to the IT organization with the Component Business Model
Many Service Level Agreements (SLAs) are loaded with technological jargon rather than concentratingon intended business results. CIOs must change this, and learn to run IT as a business witha service delivery focus.IBM Process Reference Model for IT (PRM-IT) is the foundationfor the Component Business Model for the Business of IT (CBMBoIT) that can assist with strategic decision making to transform IT into this new role.
- An Integration model for organizing IT service management
There are so many ways to implement Information Technology Service Management (ITSM) that it is hard to tell if there are gaps or overlaps between products and offerings. A seamless solution requires common terminology and approaches. An integration model helps to bring all this together, focusedon being consistent with existing practice, with clarity of expression, and practical to implement.
- IBM Service Management architecture
Today's systems management tools are fragmented by resource domain--servers are managed here, networksmanaged there, and storage is another story altogether. IBM Service Management intends to integratea portal-based User Interface, a process runtime layer, a configuration management database (CMDB), and all the various operational management products (OMPs) for each resource. For example, IBM TotalStorage ProductivityCenter is an OMP for IBM and non-IBM storage resources.
- A configuration management database architecture in support of IBM Service Management
IBM Tivoli Change and Configuration Management Database (CCMDB) holds all the configuration data of IT resources in the data center, including individual "configuration items" (CIs), as well as tracks changes. The database is populated with data from different sources, includingautomatic discovery. Relationships between CIs provides a visual representation of application dependencies.The data model uses a clever combination of Unified Modeling Language (UML) with Java persistent objects.

] recently conducted a survey that prompted readers to identify the world's most successful Research and Development (R&D) companies. The results are in: IBM was recognized as the best R&D company in the world when several different categories were evaluated, including:
- R&D spending as a percentage of revenue
- the number of patents
- new products in development
The survey considered additional information on more than 130 companies such as data on intellectual property, community service and financial growth trends. Readers were also asked five distinct questions, including the following:
- Where would you like to work based on their R&D?
- What companies have the most improved R&D in the past five years?
- What companies are the leaders in R&D?
- Which company's R&D has the strongest influence on society?
- Which company's R&D is the most proactive in high tech challenges?
Since it is often 5-15 years between when a scientist in one of our many research labs comes up with a clever idea, to when it is a market success, it is good to have external recognition for the R&D efforts we are doing right now.Here is a link to a [four-page PDF

Take for example IBM's recent breakthrough in Silicon photonics. Supercomputers that consist of thousands of individual processing nodes, typically running Linux on dual-core or quad-core processors, connected by miles of copper wires could one day fit into a laptop PC. And while today’s supercomputers can use the equivalent energy required to power hundreds of homes, these future tiny supercomputers-on-a-chip would expend the energy of a light bulb, so this solution is more "green" for the environment.According to the [IBM Press Release]:
The breakthrough -- known in the industry as a silicon Mach-Zehnder electro-optic modulator -- performs the function of converting electrical signals into pulses of light. The IBM modulator is 100 to 1,000 times smaller in size compared to previously demonstrated modulators of its kind, paving the way for many such devices and eventually complete optical routing networks to be integrated onto a single chip. This could significantly reduce cost, energy and heat while increasing communications bandwidth between the cores more than a hundred times over wired chips.
“Work is underway within IBM and in the industry to pack many more computing cores on a single chip, but today’s on-chip communications technology would overheat and be far too slow to handle that increase in workload,” said Dr. T.C. Chen, vice president, Science and Technology, IBM Research. “What we have done is a significant step toward building a vastly smaller and more power-efficient way to connect those cores, in a way that nobody has done before.”
Today, one of the most advanced chips in the world -- IBM’s Cell processor which powers the Sony Playstation 3 -- contains nine cores on a single chip. The new technology aims to enable a power-efficient method to connect hundreds or thousands of cores together on a tiny chip by eliminating the wires required to connect them. Using light instead of wires to send information between the cores can be 100 times faster and use 10 times less power than wires.
IBM has put out this one-minute video:

Dave Winer in his post[Complete New Yorker archive on a hard disk] talks about this new offering from Pexagon. According to [J&R website]:
Over 4,000 issues of your favorite magazine now sit, ready for you to search and savor, on an 80GB incredibly lightweight and travel-friendly drive. This high-performance, brushed-aluminum Hard Drive measures only 3x5-inch and can easily fit inside a purse or briefcase so show it off to your tech-savvy friends and co-workers. Plus, there is plenty of extra room on the drive for future updates. Simply install The Complete New Yorker Program (installation CD provided), then connect the drive to a USB port on your Computer and have instant access to every article, poem, short story, and cartoon including every advertisement that has appeared in the magazine since 1925.
System Requirements: Windows 2000 or XP, Mac OS X 10.3 or higher, USB 2.0 port, CD-ROM drive, 750 MB of free hard drive space, 1024 x 768 minimum screen Resolution
The 750MB of disk space required on your system probably contains the indexing/metadata search system to find articles by subject, title or author. Linux is not listed, and if 750MB of disk space are required to run the program, then perhaps this system won't work with Linux at all.
The system claims that there is extra room on the disk to ingest future issues of the magazine. I wonder why they didn't put the indexing/metadata search software on the drive itself, so that it would be self-contained, rather than having a separate installation CD.
I think this is a sign of our times. The New Yorker magazine has taken the archives that they keep anyways, and made them available in bulk, in a handy disk drive delivery system. I know several people who keep boxes and boxes of back issues of all kinds of magazines, and this certainly is an improvement.

Continuing my business trip through Canada, an article by Richard Blackwell titled [The Double Bottom Line
] yesterday's Globe and Mail
newspaper caught my attention.Here is an excerpt, citing Tim Brodhead, president of the J.W. McConnell Family Foundation in Montreal:
The bottom line for any business is making a profit, right?
But how about considering a different, or additional bottom line: helping make the world a better place to live in.
That's the radical proposition underlying the concept of "social entrepreneurship," the harnessing of business skills for the benefit of the disadvantaged.
Young investors, in particular, now want their investments to produce both financial and social returns, he noted.
Until recently, "we could either make a donation [to a charity] and get zero financial return, or we could invest and get zero social return." People now want more of both, but rules governing charities and business make that tough to accomplish.
One stumbling block is the imperative - entrenched in corporate law - that managers and directors of for-profit companies have a fiduciary duty to maximize profits. That structure is a brick wall that limits the expansion of social entrepreneurship, Mr. Brodhead said.
Some companies have embraced the new paradigm of a double bottom line, even if they are uncomfortable with the "social entrepreneur" label.
This fiduciary duty to maximize profits is discussed in the 2003 documentary[Corporation
]. However, some organizations are now trying to aligntheir goals, finding ways to benefit their investers, as well as society overall. For example, organization [ONE.org
] helped launch [Product (RED)
If you buy a (RED) product from GAP, Motorola, Armani, Converse or Apple, they will give up to 50% of their profit to buy AIDS drugs for mothers and children in Africa. (RED) is the consumer battalion gathering in the shopping malls. You buy the jeans, phones, iPods, shoes, sunglasses, and someone - somebody’s mother, father, daughter or son - will live instead of dying in the poorest part of the world. It’s a different kind of fashion statement.
Another example is IBM's recent press release [IBM Plans Investment Increase in Sub-Saharan Africa]:
The company, which has operated in Africa for nearly six decades, expects to increase its investment by more than $US120 million (more than R820 million) over the next two years. In the coming year, IBM expects to hire up to 100 students from Sub-Saharan universities to meet the growing demand in services, global delivery and software development.
"The Sub-Saharan African market is poised for double-digit growth flowing from the development and expansion of telecommunications networks, power grids and transport infrastructure," said Mark Harris, Managing Director, IBM South and Central Africa. "Private and public sector investment in the region is transforming the ability of the market to participate in the global economy."
A recent IBM Global Innovation Outlook (GIO) [report on Africa
] indicates that the economies ofdozens of African nations are growing at healthy rates, the best in the past 30 years, with 5.5 to 5.8 percent averageacross the continent. This supports last month's news that [Top IBM thinkers to mentor African students
Hundreds of IBM scientists and researchers will mentor college students in Africa. Called Makocha Minds (after the Swahili word for "teacher"), the program will reach hundreds of computer science, engineering and mathematics students.
Makocha Minds is an off-shoot of IBM’s Global Innovation Outlook, an annual symposium of top government, business and academic leaders that uncovers new opportunities for business and societal innovation. "African students need to be trained in entrepreneurship so that they get out there and not just make jobs for themselves but create opportunities to employ others as well,” said Athman Fadhili, a graduate student at the University of Nairobi (Kenya).
Most of the mentoring will be via email and online collaboration.
Mentoring via email and online collaboration is very reasonable. I have mentored both high school and collegestudents through a partnership between IBM Tucson and the Society of Hispanic Professional Engineers[SHPE]. While thekids were all located in Tucson, I rarely am, traveling nearly every week, but I madetime for the kids via email and online collaboration wherever I happened to be.

Over at StorageMojo, Robin Harris writes in his post[The High-End Storage Melt-Down
Expect to hear a lot more about the SMB segment over the next 6 months.
Because the high-end market is sucking wind. NetApp and EMC are both reporting problems in the high-end. HP and IBM don’t break out as much detail but I’m sure they are feeling the chill as well.
With Hulk/Maui coming in Q2CY08, you should hold off on any 2nd tier storage purchases you can. I estimate that H/M will be about 30% per GB less than the current gear.
Robin blames the U.S. subprime mortgage mess, butI disagree with the term melt-down.
IBM doesn't publicly report subset numbers on individual product lines, but we are growing, albeit single-digit growth, on the high-end with our IBM System Storage DS8000 and DS6000 series products. Single digit growth is not "booming", but it is what we expected in this space, so it is not like we are"feeling the chill" as Robin stated.Obviously, if the U.S. market overall is doing poorly, then it must be from something else. IBM's success appears to be from organic growth in our Asia and Europe markets, and taking marketshare away from the top two contenders, EMC and HDS. Here are my thoughts why:
- EMC is remodeling its kitchen
Not happy with its status as #1 disk hardware specialty shop, EMC is admirably trying to redefine itself as an ["information infrastructure"] company, buying up software companies and introducing new storage services. [Byte and Switch] reports onEMC's recent acquisitions:
EMC is the latest vendor to pin its colors to the SaaS mast, revealing its plan to offer SaaS-based archiving services during its recent Innovation Day in Boston.IBM has offered[Managed Storage Services] foryears through our Global Technology Services (GTS) division. Gartner recognized IBM as the #1 leader in storageservices, with three times more revenues than EMC in this space.
EMC gave another clear indication of its SaaS intentions last month, when it spent $76 million to acquire online backup specialist Mozy.
As with a restaurant that is remodeling its kitchen, it can expect a temporary drop inrevenue. If it is done right, customers will come back to a bigger brighter restaurant. If not, the restaurant re-opens as a much smaller lesser version of itself. Recent events this year might incent EMC to get that kitchen done quickly:
- A recent [class-action lawsuit]might result in having EMC's "86 percent male" sales force goes to sexual harassment sensitivity training, takingtime away from selling high-end storage arrays in the field. Analysts consider "high-end" boxes as those costingover $300,000 US dollars. Because of the money involved, there is a lot of competition for high-end storage, so face-to-face time with prospective customers is crucial to making the sale.Anytime any vendor is mentioned in a lawsuit (andcertainly IBM has had its share in the past, as Chuck Hollis correctly points out in the comment below), priorities get shifted, and there is potential dip in revenues.
- Dell acquires EMC's rival EqualLogic. Dell resold EMC midrange storage, like CLARiiON, so this should notimpact their high-end storage sales. While Dell will be allowed to sell EMC until 2011, this new acquisition mightmean Dell leads with the EqualLogic offerings, and that could potentially reduce EMC revenues in the midrange space.
IBM went through a similar phase in the 1990's, redefining itself from an "IT Technology" company, intoa "Systems, Software and Services" company. These transitions can't be done in a quarter, or even a year, theytake several years. IBM lost business to EMC in the 1990s, but is back with a stronger portfolio in the 2000's, and so IBM's kitchen remodeling effort appears to be paying off. We will see what happens with EMC in a few years.
- HDS puts on the white lab coats
Meanwhile, HDS appears interested in taking over as #1 disk hardware specialty shop.For years, Hitachi was the stereotypical JCM (Japanese IBM-compatible manufacturer) that made well-engineered"me, too" storage arrays. They would see what innovators like IBM and EMC were doing, and copy them. Recently,however, they seemed to have changed strategy, introducing new featuresand functions on their high-end USP-V device, like[Dynamic Provisioning].
The problem is that customers don't want to feel like [Guinea pigs] in an experimental lab, especially withmission-critical data that they trust to their most-available, most-reliable high-end disk storage systems.Like IBM and EMC and the rest of the major storage vendors, Hitachi has top-notch engineers making quality products, but new features scare people, and so there is a lag in the adoption of new technologies.
In our youth, we might have preferred beer with recent born-on dates, and tequila aged less than 90 days. But as weget older, we switch to drinks like wine and whiskey, aged years, not weeks. The same is true for themarketplace. New start-ups and other "early adopters"might be willing to try fresh new features and functions on their storage systems, but more established enterprises prefer storage with more mature and stable microcode.Storage admins want to leave at the end of the day, knowing that the data will still be there the next morning. In tough financial times, many established companies want the technological equivalent to ["comfort food"], nothing spicy or exotic, but simplehearty fare that fills the belly and keeps you satisfied.
Recognizing this, IBM often introduces new features and functions on its midrange lines first, and position them accordingly. Once customers are comfortable with the concepts, IBM then can consider moving them into the high-end lines. For example, dynamic volume expansion was introduced on the DS4000 and SAN Volume Controller first, and once proven safe and effective, brought over to the DS8000 series. This strategy has served us well.
Well those are my theories. If you have a different explanation of why storage vendors are not doing well in thehigh-end, drop me a comment!

I'm here at the Los Angeles airport on my way to Canada.
On my post last week[My Blook is Now Available],Cheryl Hagedorn comments:
I've just posted about your blook at Blooking Central http://blooking.blogspot.com/2007/11/inside-system-storage.html
I'll love to hear from you (I post letters from authors!) about how you put the blook together. Many folks have used cut and paste from blog page into word processor. Others have simply backed up their blogs, then cut and pasted. Some folks had the foresight to compose their posts in a word processor before posting!
Anyway, I'd like to know whatever ins and outs you'd like to share. Thanks.
Well Cheryl, I couldn't find any email address to send you a response, so Idecided to post here instead and post a traceback on your blog.
After learning about the Blooker Prize, I had asked our IBM Developerworks team if anyone else within IBM had published a blook, but nobody had heard of anything, so I had to look elsewhere.I got a lot of guidance from Lulu's [Book Publishing FAQs], and Don Campbell's[Five Steps to Publishing Your Paperback Book at Lulu],and how-to articles over at [bookcatcher.com].
- Decision 1: Defining the Container
Before you can cut-and-paste anything, you need a container file to put it in. Here were my key decisions:
- Page Size: Novel 6"x9" (15cm x 23cm) to support both perfect-bound paperback and dust-jacket hardcopy editions
- Colors: Full-color covers with black-and-white interior
- Fonts: 10pt Book Antiqua for the text, Courier for the monospaced computer examples,8pt for the "copyright" fine print
- Format: *.doc Microsoft Word file, using [Lulu's ready-to-use templates]
- Software: Office 2003 version of Microsoft Word on Windows XP system
- Front matter: Title, Copyright, Dedication, Table of Contents, Foreword, Introduction
- Back matter: Blog Roll, Blogging Guidelines, Glossary, Reference table, What people have written about me and my blog
According to Lulu, you could use OpenOffice instead with RTF files. I didn't try that. I did tryusing CutePDF to upload ready-made PDFs, that didn't work. I also tried saving text in PDF formaton my Mac Mini running OS X 10.4 Tiger, but Lulu didn't like that either.IBM now offers a free download of [LotusSymphony] that might be an alternative for my next book.
For my blook, the "Blog Roll" serves instead of a more formal [Bibliography]. I could have also includedonline magazines and other web resources.
- Decision 2: Chapter Configuration
I reviewed other blooks to see how they were organized. I thought I might organize the blog posts by topic or category, but all the blooks I looked atwere strictly chronological, oldest post first. This of course is exactly opposite as theyappear on the web browser. I decided to keep things simple, with just 12 chapters, one for each calendar month.
Each chapter was separated by a section break with unique footers, starting on odd page number. The footers have the page numbers on the outside edges, so that even pages had numbers on the left, and odd pages on the right. I also added the name of the chapter and the book, like so:
40 ................December 2006| |Inside System Storage.... 41
This was a lot of work, but makes the book look more "professional".
- Decision 3: Cut-and-Paste
People have asked me why it took three months to put my blook together, and I explainedthat the cut-and-paste process was manually intensive. My posts are either HTML entereddirectly into Roller webLogger, or typed in HTML on Windows Notepad and cut-and-pastedover to Roller later. I have access to the HTML source of each post, as wellas how it appears on the webpage, and tried cut-and-paste both ways. Copying theHTML source meant having to edit out all the HTML tags. I hadn't even looked into the idea of "backing up" through Roller all the entries, but they would probably have been HTMLsource as well.
In turned out that copying the webpage directly from the browser was better, which retains more of the formatting,and automatically eliminates all of the pesky HTML tags. I wanted the printed versions to resemblethe web page version.
Microsoft Word indicates all hyperlinks as bright blue underlined text which I didn't like, so I removedall hyperlinks, to avoid having to pay extra for "colored pages". This can be done manually, one by one, or pasting with the "text only" option butthis removes out all the other formatting as well. (Specifying black-and-white interior on Lulu might have converted all of these automaticallyto greyscale, so I might have been safe to leave them in,which I probably could have done if I wanted an online e-book version with links active, ... oh well)
To indicate where the hyperlinks would have been, I wrapped all the linked text in[square brackets]. I have now gotten in the habit of doing this for future blog posts, soif I ever make another book, it will cut down the work and effort on the cut-and-paste.
Some of the items I linked to posed a problem. I had to convert YouTube videos to flat imagesof the first frame to include them into the book. Older links were broken, and I had tofind the original graphics. I also sent a note to Scott Adams related about the use of one of his Dilbert cartoons.
I decided to also cut-and-paste my technorati tags and comments. For comments I mademyself, I labeled them "Addition" or "Response". A few people did not realize thatI was "az990tony" making the comments as the blog author, so I changed all to say "az990tony (Tony Pearson)" to make this more clear, and now do this on all future blogposts to minimize the work for my next book.
Because I used a lot of technical terms and acronyms, Microsoft Word actually gave mean error message that there were so many gramattical and spelling errors that it wasunable to track them all, and would no longer put wavy green or red lines underneath.
I did all the cut-and-paste work myself, but since the website is publicly accessible,I could have gotten someone else to do this for me.Had I read Timothy Ferriss' book The Four Hour Work Week sooner,I might have taken his advice on [Outsourcing the project to someone in India]. I might consider doing this for my next book.
- Decision 4: Numbering the Posts
I decided I wanted to standardize the title of each post. The date was not uniqueenough, as there were days that I made multiple posts. So, I decided to assign eacha unique number, from 001 to 165, like so:
2006 Dec 12 - The Dilemma over future storage formats (033)
Posts that referred back to one of my earlier posts within the book had (#nnn) added so that readers couldgo jump back to them if they were interested. This eliminated trying to keep track of pagenumbers.
- Decision 5: Adding behind-the-scenes commentary
- One of the reasons I rent or buy DVDs is for the director's audio commentary and deleted scenes. These extras provided that added-value over what I saw in the movietheatre. Likewise, 80 percent of a blook is already out in the public for reading, so I felt I needed to provide some added value. At the beginning of each month, I describewhat is going on behind the scenes, and then in front of specific posts, I providedadditional context. This could be context of what was going on in the blogosphere at thetime, announcements or acquisitions that happened, what country I was blogging from, orwhat unannounced products or projects that were being developed that I can now talk aboutsince they are now announced and available.
To distinguish these side comments from the rest of the blog posts,I decorated them with graphics. Searching for copyright-free/royalty-free clip-art, graphics, and photos that represented eachconcept was time-consuming. I shrunk each down to about 1 inch square in size, and changed themfrom color to greyscale. (LuLu conversion to PDF probably would have automaticallyconverted the color graphics to greyscale for me, in which case leaving them in full colormight have been nice for an e-book edition, ... oh well)
I did complete each chapter one at a time. So, for each month, I cut-and-pasted all the blog posts,tags and comments, then fixed up and numbered all the post titles, then added all the behindthe scenes commentary, and cleaned up all the font styles and sizes. I recommend you do this at least for the first chapter, so you can get a good feel for what the finished version will look like.
- Decision 6: Adding a Glossary
I sent early copies of the books to five of my coworkers knowledgeable about storage, andfive local friends who know nothing about storage.
Some of my early reviewers suggested having an index, so that people can find a specific poston a particular topic. Others suggested I spell out all the acronyms that appear everywhereand put that into the Reference section, rather than on each and every occurrence inthe book itself. Both were good ideas, and my IBM colleague Mike Stanek suggested calling ita GOAT (Glossary of Acronyms and Terms). Acronyms are spelled out, and terms or phrasesthat need additional explanation have a glossary definition. For eachitem, I put the post or posts that uses that term. Some terms are covered in dozens ofposts, so I tried to pick five or fewer posts representing the most pertinent.
The glossary was far more time-consuming than I first imagined, with over 50 pages containingover 900 entries. I struggled deciding which terms and acronyms needed explanation, and which were obvious enough. On the good side, itforced me to read and re-read the entire book cover to cover, and I caught a lot of othermistakes, misspellings, and formatting errors that way. Also, I have a large internationalreadership on my blog, so the glossary will help those whose English is not their native language,and will help those readers who are not necessarily experts in the storage industry.
- Decision 7: Designing the Covers
Up to this point, I had been printing early drafts with simple solid color covers. Lulu hasthree choices for covers:
- Just type in the text, upload an "author's photo" and chose a background color or pattern
- Upload PNG files, one for the front cover, one for the back cover, and chose the textand color of the spine.
- Upload a single one-piece PDF file that wraps around the entire book.
I had no software to generate the PDF for the third option, so I decided to try the secondoption. My first attempt was to format the front title page in WORD, capture the screen,convert to PNG and upload it as the front cover. I did same for the back cover, with a smallpicture of me and some paragraphs about the book.
I chose a simple straightforward title on purpose. Thousands of IBM and other IT marketing and technicalpeople will be ordering this book, and submitting their expenses for reimbursement as work-related, and didn't want to cause problems with a cute title like "An Engineer in Marketing La-La Land".
The next step was to use [the GIMP] GNU image manipulationprogram, similar to PhotoShop, to add a cream colored background, a slanted green spine, and some graphics that we had developed professionally for some of our IBM presentations.I learned how to use the GIMP when making tee-shirts and coffee mugs for our [Second Life] events, so I was already familiar. For newblook authors, I suggest they learn how to use this for their covers, or find someone who can do thisfor them.
I did the paperback version first, and once done, it was easy to use the same PNG files forthe dust jacket of the hardcover edition, adding some extra words for the front and back flaps.
The adage "Don't judge a book by its cover" seems to apply to everything except booksthemselves. The book cover is the first impression online, and in a bookstore. I have seenpeople pick books up off the shelf at my local Barnes & Noble, read the front and back covers, peruse the front and backflaps, and make a purchase decision without ever flipping a single page of the contents inside.From an article on Book Catcher [SELF-PUBLISHING BOOK PRODUCTION & MARKETING MISTAKES TO AVOID]:
According to selfpublishingresources website, three-fourths of 300 booksellers surveyed (half from independent bookstores and half from chains) identified the look and design of the book cover as the most important component of the entire book. All agreed that the jacket is the prime real estate for promoting a book.
While many struggle to find the right title and cover art, I think it is interesting that Lululets you post the same book with slightly different titles and covers, each as separate projects, and let market forces decide which one people like best. This is a common practice among marketresearch firms.
- Decision 8: Finding someone to write the Foreword
With the book nearly done, I thought it would be a nice touch to have an IBM executive write a Foreword at the frontof the book. Several turned me down, so I am glad I found a prominent Worldwide IBM executiveto do it. I should have started this process sooner, as she wanted to read my book in its entirety beforeputting pen to paper. I had not planned for this. I was hoping to be done by end of October,but waiting for her to finish writing the Foreword added some extra weeks. Next time,I will start this process sooner.
- Decision 9: Printing Early Drafts
You need to have Lulu print at least one copy to review before making it available to the public,and it doesn't hurt to order a few intermediary draft copies to make sure everything looks right.However, from the time I order it on Lulu, to the time it is in my hands, is over two weeks withstandard shipping, so I needed a way to print drafts to look at in between.
To avoid wear-and-tear on my color ink-jet printer, I went and bought a large black-and-white[Brother HL-5250DN] laser printer. Rather than buying specialty 6x9 paper, I used standard 8.5x11 paperusing the following 2-up duplex method:
- Upload the DOC file to Lulu, and get it converted to PDF
- Download the resulting PDF from Lulu back to your computer
- View the PDF in Adobe Reader, and print it using 2-up "Booklet" mode.
For example, if you print 60 pages in booklet mode, it prints two mini-pages on thefront side, and two more mini-pages on the back side of each sheet of paper, resulting in 15 standard 8.5" x 11" pages that can be folded, stapled, and read like a mini-booklet. My entire blook could be printed on seven of these mini-booklets, saving paper, and giving me a close approximation to what the final book would look like. Eachmini-page is 5.5"x8.5", so just slightly smaller than the final 6"x9" form factor.I fount that 60 pages/15 sheets was about the maximum before it becomes hard to fold in half.
So, if I had to do it all over again, I might have chosen 11pt Garamond (the default), or changedthe default to 11pt Book Antiqua up front, so as not to have spend so much time converting thefonts. I might have left out the glossary. I might have left in all the hyperlinks and graphicsin full color for a separate e-book edition. And I definitely would have looked for an author formy Foreword much earlier in the process.
I didn't plan to write a blook when I started blogging. I have started putting [square brackets]around all my links. I have started putting "az990tony (Tony Pearson)" on all my comments. I hadassumed that people were jumping to all the links I provided in context, but I learned that the blogpost has to stand on its own, so now I make sure that I either paraphrase the important parts, oractually quote the text that I feel is important, so that the blog post makes sense on its own.This is perhaps good advice in general, but even more important if you plan to write a blook later.
Lastly, I decided up front to write blog posts that were 500-700 words long, about the average lengthof magazine or newspaper articles. In my blook, the average is 639 words per post, so I hit thatgoal. I have seen some blogs where each post is just a few sentences. Maybe they are posting fromtheir cell phone, or don't have time to think out a full thought, but who wants to read a year'sworth of [twitter] entries.
Well Cheryl, I hope that helps. If you need anymore, click on the "email" box on the right panel.

HealthAlliance Hospital has implemented an IBM System Storage Grid Medical Archive Solution (GMAS) to make patient records available to clinicians anytime, anywhere. IBM has a [Case Study
] on this implementation.Here is an excerpt from the IBM [Press Release
HealthAlliance Hospital, a member of UMass Memorial Health Care, serves the communities of north-central Massachusetts and southern New Hampshire with acute care facilities, a cancer center, outpatient physical therapy facilities and a remote home health agency. As an investment in continued high-quality patient care, the hospital has implemented a picture archiving and communication system (PACS) from Siemens Medical Solutions so that it can move toward digital health records while eliminating traditional paper and film.
HealthAlliance is now able to make all of their data, including PACS images, available instantly, using the IBM GMAS, a cross-IBM offering comprised of storage, software, servers and services. The GMAS solution provides hospitals, clinics, research institutions and pharmaceutical companies with an automated and resilient enterprise storage archive for delivering medical images, patient records and other critical healthcare reference information on demand.
"Fast, easy access to diagnostic images is a priority," said Rick Mohnk, Vice President and Chief Information Officer of HealthAlliance. "Being paperless not only helps our staff improve their productivity and the quality of patient care, but also lowers our costs and improves our competitiveness. The IBM GMAS has helped us stay competitive and offer the leading edge technology that attracts top physicians to our staff and keeps patients feeling comfortable and well cared for."
Normally when you read or hear the term "grid", you might think of supercomputers, but in this case we are talking about information that is accessible from different interconnected locations. I've mentioned GMAS before in my posts [Blocks, Files and Content Addressable Storage and What Happened to CAS?] but I thought I would provide more detail on the elements of the solution.
Medical imaging equipment are called "modalities", which is just fancy hospital talk for "method of treatment".These have Ethernet connections designed to write to any storage with a CIFS or NFS interface. For example, press the button on the "X-ray" machine, and the digitized version of the X-ray is stored as a file to whatever NAS storage on the other end.
[Picture Archiving and Communication System] refer to the application and the computer equipment to manage these medical images, often stored in a DICOM format and indexed with HL7 metadata headers. There are many PACS vendors, GE Medical Systems, Siemens Medical, Agfa, Fuji, Philips, Kodak, Stentor, Emageon, Brit Systems, Mckesson, Amicus, Cerner, Medweb and Teramedica, to name a few. Many PACS providers embedded specific storage as part of their solution, but now are starting to realize that they need to be part of a larger storage infrastructure.
IBM System Storage [Multi-Level Grid Access Manager] is softwareon IBM System x servers that manages access across the grid of inter-connected hospitals, clinics and imaging facilities. It provides the NFS and CIFS interfaces to the modalities, and places the data into a GPFS file system on DS4000 series disk.
- GPFS and DS4000 series disk
IBM [General Parallel File System] has all the Information Lifecycle Management (ILM) capabilities to move data from one disk storage level to another, automates deletion based on expiration date, and can provide concurrent access from multiple requesters.The IBM System Storage DS4000 series disk products can support both high-speed FC disk as well as low-cost SATA disk.For large medical images, the SATA disk is often a good fit. The advantage of GPFS is that you can have policies todecide which images are placed on FC disk, and which on SATA, and then later move these files based on access reference. Images that are accessed the most frequently can be on FC disk, and those that haven't been accessed in a while on SATA disk.
- TSM space management
IBM [Tivoli Storage Manager for Space Management] supports moving files out of the GPFS file system and onto tape, based on policies. For example,keep the most recent 18 months on disk, and anything older than that gets moved to tape. This is similar to themigrate/recall technology used in DFSMShsm on the mainframe.
- Tape Library automation
Before GMAS, paper and film images had to be retrieved manually from shelves and filing cabinets. The massive amountsof data being stored, and for such long periods of time, makes it impractical to store all of it on disk. With tape automation, any medical image more than 18 months old can be retrieved in minutes. Patients with an appointment can have all of their medical images retrieved in bulk the night before. Emergency room patients can have previous images retrieved while admission clerks check for insurance coverage and perform triage.
- Display Screen
Images archived on the IBM GMAS are accessible in numerous ways. For example, all clinicians can access GMAS through hospital record system, which provides complete paperless and filmless access to the patient record including medical images, lab results, radiology reports, and pharmacy records. Medical workers at any location can also access the grid using their Web browsers. This allows each employee to use the display systems they are already familiar with.
Unlike disk-only based NAS systems, IBM's blended disk-and-tape approach makes this a much more cost-effective solution.For more details on IBM GMAS, read this 6-page[Frost & Sullivan whitepaper

Today, IBM announced a software/server/storage combo that out-performed both HP and Sun. Here is an excerpt from the[IBM Press Release
IBM today announced that its recently introduced E7100 Balanced Warehouse(TM), consisting of the IBM POWER6(TM) processor-based System p(TM) 570 server, the IBM System Storage(TM) DS4800 and DB2(R) Warehouse 9.5, is already lapping the field in performance. The new data warehousing solution is now ranked number one in both performance and in price/performance in the TPC-H business:
- 2 x speed-up over HP system with Oracle 10g and equal number of cores;
- 3.17 x speed up over Sun with Oracle 10g and 38 percent price advantage;
- A new world record by loading 10 terabytes (TB) data at six TB per hour (TB/hr).
"These latest benchmark results further prove IBM's strength and leadership in the business intelligence arena," said Scott Handy, vice president of marketing and strategy, IBM Power Systems. "The E7100 Balanced Warehouse is a complete data warehousing solution comprised of pre-tested, scalable and fully integrated system and storage components, designed to get customers up and running quickly to get to the real benefit of unprecedented business insight and intellect."
Those not familiar with the [IBM Balanced Warehouse], it is the productized version of DB2's ["Balanced Configuration Unit" or BCU] reference configuration. The IBM Balanced Warehouse presents a pre-tested, pre-configured solution for Business Intelligence (BI) applications. These are in the form of "building blocks" thatcan be combined to get to the size you need, with incremental growth as your business expands. Each building block expertly matches the CPU processor and RAM memory of the server, with the appropriate I/O bus, cabling, and capacity of the disk system, resulting in optimal performance.
IBM DB2 software is designed to allow you to combine multiple building blocks into a single system image. This greatly simplifies your data warehouse deployment, and can help ensure success. For example, for a 50TB deployment, you can take a base 2TB building block, add 24 more, each with 2TB of disk capacity, and have a completely balanced environment. IBM clients have built systems over 300TB in this manner with these building blocks.
The IBM Balanced Warehouse is offered in several configurations:
The [C-class models] are designed for SMB customers, employing an IBM System x server with internal or direct attached EXP3000 disk.
The [D-class models] are the next step up, offering department-level data marts and data warehouse for larger deployments, employing an IBM System x server with EXP3000 or System Storage DS3400 entry level disk.
The [E-class models] represent our top-of-the line configurations for our largest enterprise deployments. The [E6000] run Linux on an IBM System x server with System Storage DS48000 disk. The [E7000] run AIX on an IBM System p575 server with DS4800 disk. The new [E7100] mentioned above runsAIX on a POWER6-based IBM System p570 with DS4800 disk.
As I have mentioned before, in my post[Supermarketsand Specialty Shops],companies are looking for complete solutions, preferably from a single vendor like IBM, HP and Sun, rather than buying piece part components from different vendors and hoping the combined ["Frankenstein"] configuration meets business requirements.
The DS4800 is an obvious choice for this solution, providing an excellent balance of cost and performance, in a modular packaging that is ideal for the incremental growth design inherent in the IBM Balanced Warehouse philosophy. To learn more about this disk system, see the official [DS4800 website] for details, descriptions and specifications.

You can choose between hardcover (with dust jacket) or paperback versions:
This is not the first time I've been published. I have authored articles for storage industry magazines, written large sections of IBM publications and manuals, submitted presentations and whitepapers to conference proceedings, and even had a short story published with illustrations by the famous cartoon writer[Ted Rall].
But I can say this is my first blook, and as far as I can tell, the first blook from IBM's many bloggers on DeveloperWorks, and the first blook about the IT storage industry.I got the idea when I saw [Lulu Publishing] run a "blook" contest. The Lulu Blooker Prize is the world's first literary prize devoted to "blooks"--books based on blogs or other websites, including webcomics. The [Lulu Blooker Blog] lists past year winners. Lulu is one of the new innovative "print-on-demand" publishers. Rather than printing hundredsor thousands of books in advance, as other publishers require, Lulu doesn't print them until you order them.
I considered cute titles like A Year of Living Dangerously, orAn Engineer in Marketing La-La land, or Around the World in 165 Posts, but settled on a title that matched closely the name of the blog.
In addition to my blog posts, I provide additional insights and behind-the-scenes commentary. If you go to the Luluwebsite above, you can preview an entire chapter in its entirety before purchase. I have added a hefty 56-page Glossary of Acronyms and Terms (GOAT) with over 900 storage-related terms defined, which also doubles as an index back to the post (or posts) that use or further explain each term.
So who might be interested in this blook?
- Business Partners and Sales Reps looking to give a nice gift to their best clients and colleagues
- Managers looking to reward early-tenure employees and retain the best talent
- IT specialists and technicians wanting a marketing perspective of the storage industry
- Mentors interested in providing motivation and encouragement to their proteges
- Educators looking to provide books for their classroom or library collection
- Authors looking to write a blook themselves, to see how to format and structure a finished product
- Marketing personnel that want to better understand Web 2.0, Second Life and social networking
- Analysts and journalists looking to understand how storage impacts the IT industry, and society overall
- College graduates and others interested in a career as a storage administrator
And yes, according to Lulu, if you order soon, you can have it by December 25.

For those in the US, last friday, the day after Thanksgiving, marks the official start of the Holiday shopping season. This has been called [Black Friday
] as some stores open as early as 4am in the morning, when it is still dark outside, to offer special discount prices. Some shoppers camp out in sleeping bags and lawn chairs in front of stores overnight to be the first to get in.
Not surprisingly, some folks don't care for this approach to shopping, and prefer instead shopping online. Since 2005, the Monday after Thanksgiving (yesterday) has been called [Cyber Monday].USA Today newspaper reports [Cyber Monday really clicks with customers]. Many of the major online shopping websites indicated a 37 percent increase in sales yesterday over last year's Cyber Monday.
On Deadline dispels the hype on both counts:[Cyber Monday: Don't Believe the Hype?"], indicating that Black Friday is not the peak shopping for bricks-and-mortar shops, andthat Cyber Monday is not the busiest online shopping day of the year, either.
Despite the controversy, all of this increased use of the internet could lead to what is now being termed an "Internet Brown-out" in the next few years.Magaret Rouse of [IT Knowledge Exchange] points to this MacWorld article by Grant Gross titled [Study: Internet could run out of capacity in two years]. Here's an excerpt:
A flood of new video and other Web content could overwhelm the Internet by 2010 unless backbone providers invest up to US$137 billion in new capacity, more than double what service providers plan to invest, according to the study, by Nemertes Research Group, an independent analysis firm. In North America alone, backbone investments of $42 billion to $55 billion will be needed in the next three to five years to keep up with demand, Nemertes said.
Internet users will create 161 exabytes of new data this year, and this exaflood is a positive development for Internet users and businesses, IIA says.
If the "161 Exabytes" figure sounds familiar, it is probably from the IDC Whitepaper [The Expanding Digital Universe] that estimated the 161 Exabytes created, captured or replicated in 2006 will increase six-fold to 988 Exabytes by the year 2010. This is not just video captured for YouTube by internet users, but also corporate data captured by employees, and all of the many replicated copies. The IDC whitepaper was based on an earlier University of California Berkeley's often-cited 2003[How Much Info?] study, which not only looked at magnetic storage (disk and tape), but also optical, film, print, and transmissions over the air like TV and Radio.
A key difference was that while UC Berkeley focused on newly created information, the IDC study focused on digitized versions of this information, and included theadded impact of replication.It is not unusual for a large corporate databases to be replicated many times over. This is done for business continuity, disaster recovery, decision support systems, data mining, application testing, and IT administrator training. Companies often also make two or three copies of backups or archives on tape or optical media, to storethem in separate locations.
Likewise, it should be no surprise that internet companies maintain multiple copies of data to improve performance.How fast a search engine can deliver a list of matches can be a competitive advantage. Content providers may offer the same information translated into several languages.Many people replicate their personal and corporate email onto their local hard drives, to improve access performance, as well as to work offline.
The big question is whether we can assume that an increased amount of information created, captured and replicated will have a direct linear relation to the growth of what is transmitted over the internet. Three fourths of the U.S. internet users watched an average of 158 minutes of online video in May 2007, is this also expected to grow six-fold by 2010? That would be fifteen hours a month, at current video densities, or more likely it would be the same 158 minutes but of much higher quality video.
On the other hand, much of what is transmitted is never stored, or stored for only very short periods of time.Some of these transmissions are live broadcasts, you are either their to watch and listen to them when they happen, or you are not. Online video games are a good example. The internet can be used to allow multiple players to participate in real time, but much of this is never stored long-term. An interesting feature of the Xbox 360 is to allow you to replay "highlight" videos of the game just played, but I do not know if these can be stored away or transferred to longer term storage.
Of course, there will always be people who will save whatever they can get their hands on. Wired Magazine has anarticle [Downloading Is a Packrat's Dream], explaining that many [traditional packrats] are now also "digital packrats", and this might account for some of this growth. If you think you might be a digital packrat,Zen Habits offers a [3-step Cure].
In any case, the trends for both increased storage demand, and increased transmission bandwidth requirements, are definitely being felt. Hopefully, the infrastructure required will be there when needed.

I hope everyone had a great weekend!
Technology Review has a great 6-minute video showing how the PowerTune system works in the ['self-tuning' guitar].
As with any self-tuning equipment, there are three essential parts.
- Measurement. In the case of the guitar, small sensors identify the current note based on string tension.
- Response. Based on the measurement, the self-tuning system either decides that there is no more to do, or to take specific action. In the case of this guitar, the action would be to loosen or tighten the string.
- Action. The action taken that is expected to get closer to the desired result. In this case, tiny motorsinside the handle turn the thumbscrews to loosen or tighten the strings accordingly.
These are part of a "closed-loop design", as it is called in [Control Theory].After the action in step 3 is taken, goes back to step 1, takes a new measurement, and determines a new response. Thiscould mean that the string is tightened and loosened by ever smaller amounts until it is close enough to the desiredaccuracy, in this case an impressive two [cent].
On the server side, IBM has offered this for years. For example, for z/OS applications on System z mainframes, the[Workload Manager (WLM) offers a "goal mode"] that allows you to set desired results for your business applications, for example, how quickly they respond in processing transactions. WLM measures the response time of the transactions, determines anappropriate response if any, and takes action to shift processor cycles (MIPS) or RAM to help out the workloads with the highest priority, in some cases stealing cycles and RAM away from lesser priority tasks.
For storage, we have IBM TotalStorage Productivity Center. It can scan for file systems over 90 percent full, for example, determine an appropriate response based on policies, and take action to expand the file system to a larger size.This may involve dynamically expanding the LUN that the file system sits on, a feature available on IBM SAN VolumeController, DS8000 series, DS4000 series and N series disk systems.This is the kind of closed loop design that can help eliminate those pesky phone calls at 3am.
But why focus on just storage alone? Combining servers and storage into a higher-level closed loop design is accomplished with [IBM Tivoli Intelligent Orchestrator] and [IBM Tivoli Provisioning Manager]. In thiscombo, Orchestrator measures and responds, and can invoke Provisioning Manager workflows to take action. Workflows are like scripts on steroids. Unlike normal scripts which run on a single machine, workflows can communicate with multiple servers, storage and even networking gear to take the appropriate actions on each of those machines, like install updated software, carve a new LUN, or define a new SAN zone.
The products are well integrated with TotalStorage Productivity Center for the storage aspects.

Matt Hamblen of ComputerWorld writes:
Cisco Systems Inc. has been staging virtual meetings between developers and channel partners in Second Life for more than a year, but this invitation was a first for me. So a presentation announcing the winners of a networking technology innovation contest -- inside a Second Life simulation -- seemed like the place to be.
I'm probably an SL noob (for newbie) by most standards, but I've spent enough time there to know most of the ways to move and how to search out islands and events.
In all, I would say the Cisco event sparked my interest in the SL virtual meeting format, but my attention was focused more on making things in SL work smoothly than on the material presented.
I've had some interesting conversations with event-coordinators looking for advice on setting up events in Second Life, so I suspect that is a good sign that this is still growing momentum.

Wrapping up my week's theme on "Innovation that matters", I would explore how sometimes innovations are inspired by thinking differently in solving problems, and observing howothers solve similar problems in other domains.
Take for example this little Shell Oil[RealEnergy "Eureka"] video webisode. It's about eight minutes long, and helps explain a recent innovation Shellmade to help extract oil from awkward locations. Look for how the engineer was inspired by observing something his son did, that he in turn applied to innovatively solve this challenging problem.
Thinking differently has helped IBM innovate as well. Today, IBM announced it has shippped its 10,000th Storage Virtualization Engine, which coincidentally happens to correspond with today's GA date of SVC 4.2.1 release. From the [IBM Press Release]:
"IBM has been delivering virtualization capabilities for more than 40 years and today we unveil a milestone in the area of data storage virtualization with the shipment of 10,000 storage virtualization engines -- a fact no other storage company in the world can claim," said Kelly Beavers, Director, Storage Software, IBM. "By working across multiple platforms, IBM's storage virtualization helps to lower energy costs and unlocks the proprietary hold that other storage vendors have had on customers for years -- which IBM believes makes storage virtualization the killer application in the storage industry over the next decade."
SVC helps improve flexibility and responsiveness of IT infrastructures, such as creating a single virtual pool of information across the enterprise, enabling IT departments to respond more quickly to business needs and manage resources more flexibly. Benefits including increased resiliency, better application availability, simplified data migrations, and improved resource utilization can all be achieved through storage virtualization and these benefits are increased further when SVC is coupled with server virtualization such as through IBM System p LPARs and VMware ESX Server.
IBM's storage virtualization helps to unlock the proprietary hold that vendors such as EMC, HP and Hitachi have had on customers for years. With IBM SVC, customers can choose any combination of supported EMC, IBM, HP, Hitachi or other devices, virtualize them, and manage and deploy them easily and with greater flexibility and independence than ever before.
You can also read this[MarketWire] article.
I've posted before on IBM's [history of storage virtualization], but there are still a few folks not convinced.Dr. Kevin McIsaac has an article on ComputerWorld[Vendor Claims on Storage Virtualization] that warns against vendor hype. Dr. McIsaac feels"network-based storage virtualization results in a lowest common denominator view of the infrastructure, eliminating the value-added features of the array." This is really not a "network" issue, as this applies equally to Hitachi's USP-V directly cabled to external storage, no network required.IBM BarryW gives his take [Lowest Vendor Neutral Denominator] on his blog.
The concern that adding SVC (or USP-V) in front of other disk arrays adds complexity or eliminates the value-added features of older technologies, can be addressed simply by observing how similar problems were solved by the automobile industry.
- In 1911, the automobile industry introduced the "electric starter", eliminating the value-added features of the "hand crank".Instead of standing in front of the vehicle turning a hand crank over and over until the engine started, the driversat inside the vehicle and turned a small key or pressed a button, and let the "electric starter" do it. Yes, this meant thatcars were more complicated by adding a battery and electric system, but it also made cars easier to start and drive. Despite manufacturers arguing why their hand cranks were better than the hand cranks of other manufacturers, automobile models with hand cranks disappeared by 1920.
- In 1934, the automobile industry introduced the "automatic transmission" eliminating the value-added featuresof the "stick shift" and "clutch pedal". Before, people had to know when to shift gears manually, depending ontheir speed, engine RPM, and steepness of the hill they are driving on, pressing the clutch pedal at the same time, requiring skilled hand-foot coordination. Yes, cars weremore complicated with more equipment under the hood, but it made them easier and safer to drive, with one less thing to distract the driver. Surprisingly cars with automatic transmissions can be more energy-efficient, employing best practices when to automatically shift gears to optimize fuel economy.
While you can still purchase automobiles with manual transmission, the newer hybrids and electric vehiclesnearly universally all have automatic transmission. Not everyone is skilled enough to drive a car with manual transmission, something to consider when you decide which car to take on a cross-country road trip if you want to share the driving responsibilities with the rest of your group.Not surprisingly, rental car companies like Hertz offer primarily cars with automatic transmission, both forincreased safety, and to broaden the reach to all driving skill levels.
- In 1946, the automobile industry introduced "power windows", eliminating the value-added features of the window-crankon each door to roll the window up or down. Now you just press or pull a lever or button, until the window reaches the desired position. Yes, this means that cars are yet again more complicated,with little motors inside each door panel, but it made them easier to use, with the added safety option to lock out children from rolling down the back windows.
Some people actually choose manual windowsout of fear of driving their car into a lake or river, assuming a window-crank may make the difference in escaping the vehicle. It is these kinds of highly-unlikely scenarios that cause people to make bad purchase decisions. A betterapproach is to learn how to [escape from a sinking vehicle] properly, and keep the right "window-breaking" tools on hand. I keep a hammer for this purpose, and while you might think that Tucson has norivers or lakes to worry about, we do have flash floods, and I'll take knowledge-plus-hammer over window-crank any day.
So, when a company or industry innovates a new way of doing something, changing the way people think about the problem, it might take a while to take effect. SVC has been well-received in the marketplace, with thousands of delighted clients in production.

Continuing this week's theme of "Innovation that Matters", today I'll discuss cell phones, and their rolein "cloud computing". Some people call these "cellular phones", "mobile phones" or "hand phones".I have posted about these topics before. Last January, I discussed the[Convergence
]represented by Apple's iPhone, and in August, I talked about[Accessing Data in the Clouds
], but some recent announcements bring this back up as a fresh topic.
With the [end of the PC era] upon us,IBM researchers John J. Barton, Shumin Zhai, and Steve B. Cousins from the Almaden Research Center wrote aresearch paper [Mobile Phones Will Become The Primary Personal Computing Devices], and USA Today reports that [Social networkers reach out more with cellphones]. Of course, telephones, including those attached to land lines, have always been used for social networking since the late 1800s, to arrange parties, reunions, and other get-togethers, but this article is referring to the new "Web 2.0" meaning of social networking, with services like Facebook, Flickr, MySpace and Twitter.
This is a major game-changer, forcing companies to rethink many of their strategies. For example,John Windsor, on The YouBlog asks the CBS Interactive division[What Business Are You In?]The answer is that CBS is shifting from a content focus, to an audience focus, looking to provide CBS television contentto an audience of cell phone users.ThinkBeta [Me, My Cell Phone and I] presents some interesting statistics. Google CEO Eric Schmidt estimates there are over 2.5 billion cell phones in use today, with 288 million units shipped alone in 3Q07.
That's quite a trend. As a leader in IT innovation, IBM tries to stay one step ahead of the industry, selling off mature technologies to other manufacturers, like typewriters, printers, and most recently laptops and desktop PCs, so that it can focus on newer technologies and market trends. For example, while many people might be aware that IBM designs and fabricates processor chips for all of the major game consoles (Microsoft's Xbox 360, Nitentendo's Wii, and Sony'sPlay Station 3), they might not know that IBM also makes chips for many cell phone manufacturers. IBM[POWER Architecture] blog writes about the IBM CMOS 7RF SOI semiconductor:
IBM has managed to integrate seven Radio Frequency (RF) front-end functions onto this single CMOS chip using silicon-on-insulator (SOI) technology. And this means? For cell phones, according to IBM foundry product director Ken Torino, "Our solution minimizes insertion loss and maximizes isolation which will prevent dropped calls even on the most inexpensive handsets." Currently, cell phone RF front-end functions are handled by five to seven chips and at least two of those are using expensive gallium arsenide (GaA) technologies. The CMOS 7RF SOI should not only reduce costs by eliminating the need for so many chips, but also trim the fat from materials expenditures since GaA tech is somewhat expensive. IBM predicts that manufacturers will first use the chip to reduce on-phone processors to two or three before making the leap to a single chip.
With all this demand, the world will need engineers to develop softwareapplications that work in this new environment. This plays into IBM's strength in the area of grid and supercomputing.IBM and Google announced they have jointly established an Internet-scale computing initiative to promote new software development methods that can help students and researchers address the challenges of Internet-scale applications. From[IBM Internet-scale computing] webpage:
Internet use and content has grown dramatically, fueled by global reach, mobile device access, and user-generated Web content, including large audio and video files. More of the world population is looking to the mobile Web to fulfill basic economic needs. To meet this challenge, Web developers need to adopt new methods to address significant applications such as search, social networking, collaborative innovation, virtual worlds and mobile commerce.
The University of Washington is the first to join the initiative. A small number of universities will also pilot the program, including Carnegie-Mellon University, Massachusetts Institute of Technology, Stanford University, the University of California at Berkeley, and the University of Maryland. In the future, the program will be expanded to include additional researchers, educators and scientists.
The heart of the project is a large cluster of several hundred computers (a combination of Google and IBM systems) that is planned to grow to more than 1,600 processors. Students will access the cluster through the Internet to test their parallel programming projects. The cluster is powered with open source software, including:
The project includes a Web site to encourage collaboration among universities in the program, built with Web 2.0 technologies from the [IBM Innovation Factory].

Continuing my week's theme on Innovations that matter, I thought I would tackle energy efficiency and the recent excitement over the Smart car.
USA Today had an article [America crazy about breadbox on wheels called Smart car]. This car weighs only 2400 pounds, gets a respectable 33 MPG City,and 40 MPG Highway, with a list price of $11,590 US dollars. These have been in Europe for some time now.The "Smart" name comes from combining the S from Swatch, the M from Mercedes and ART. The car was designed byNicholas Hayek, founder of the SWATCH wristwatch line, and manufactured by Daimler, who also makes Mercedes cars.
We have many communities here in Tucson that people drive street-legal golf carts. People don't realize but bothelectric and electric/gas hybrid golf carts have been around for a long time. Some of the nicer golf carts run forabout $7,000 US dollars, with a shelf on the back that can hold two sets of golf clubs, or groceries.Of course, you would never take a golf cart on the highway, so that is where the Smart car comes in, with a 10gallon tank, could easily get you from one major city to another.
Like golf carts, the Smart-for-Two model being sold in the US will hold only two people, which is perfect for manyAmerican families. The standard 4-person or 5-person sedan is too big for most DINKS (Dual Income, No Kids), and other families with kids often opt for the 7-person SUV instead.
It is good to see that energy consumption is finally getting the attention it deserves. IBM recently announced some exciting offerings to help data centers manage their energy consumption:
- IBM Systems Director Active Energy Manager V3.1 [AEM]:
A new, key component of IBM's [Cool Blue portfolio] offering, AEM helps clients manage and even potentially lower energy costs. According to Gartner, insufficient power and excessive heat remain the greatest challenges in the data center. With AEM, IT managers can understand exact power/cooling costs, manage the efficiency of the current environment and reduce energy costs. AEM is the only energy management software tool that can provide clients with a single view of the actual power usage across multiple IBM platforms, including x86, blades, Power and storage systems, with plans to extend support to the mainframe.
- IBM Usage and Accounting Manager Virtualization Edition V7.1 [UAV]for System p and System x:
UAV gives IT managers more information to manage data center costs. These powerful usage management tools are designed to accurately measure, analyze, and report resource utilization of virtualized/consolidated/shared resources. With UAV, IT managers can better manage costs and justify new systems by determining who is using how much of which resource; assessing the cost of an IT service or application; and accurately charging each user or department. Working with AEM capabilities, it will also allow tracking of energy consumption costs by server and by user. This level of reporting eliminates a key inhibitor to the adoption of virtualization and consolidation and further differentiates IBM systems.
- IBM Tivoli Usage and Accounting Manager[UAM]:
This solution -- ideal for heterogenous IT shops -- serves as an accurate measurement tool underlying billing processes and SLA compliance. UAM provides usage-based accounting and charging for virtually any IT resources across the enterprise -- ranging from mainframes to virtualized servers to storage networks and more. The Usage and Accounting Manager Virtualization offerings seamlessly integrate into it.
Whether you are trying to reduce energy consumption in your data center, or in your transportation around town, these innovations can help you stay "green".

Continuing my theme of "Innovation that matters", I thought I would cover MapQuest and NeverLost.
When Shawn Callahan on Anecdote wrote[Our need for the knowledge worker is over], he was referring to the fact that we no longer need the term "knowledge worker", because practically everyone isa "knowledge worker" today. He asks "How does knowledge help us to work better?"
It is said that as much as 30 percent of a knowledge worker's time is spent looking for information to do their jobs. This could be information to make a decision, decide between several choices, take specific action, or schedule when these actions should take place. The logistics of planning a business trip, and actually navigating in unfamiliarsurroundings, is a good example of this, and presents some unique challenges.
- Before these technologies
Before these technologies, to plan a trip involved finding someone who lives or has been to the destination city,can recommend hotels and restaurants near the meeting facility, and can suggest approximate times it would take to drive from one place to another. I would bring a compass, and would shop for a city map, either before leaving, or upon arrival.
On one trip to Raleigh, I asked a local IBMer who lived in Raleigh for a hotel recommendation. The hotel was nice,but involved a long 45-60 minute commute each day to the meeting facility. When I asked her why she suggested thatparticular hotel, she said it was because it was "close to the airport". I have since learned never to ask for "best" of anything, as this is subject to such interpretation.
On another trip, I was travelling with a colleague in Germany. He asked how I knew which bus to take, and which bus stop to wait at. I pulled out my compass, and told him that based on the schedule, the bus that went in a specific directionmust be the correct one. The entire bus load of people burst out laughing, that we fit the universal stereotype ofmen who refuse to ask for directions. This method works only in Germany, where timeliness is next to godliness. In other countries, time schedules are more of a suggestion.
Sometimes, maps of the destination city were not always easy to find. Now with the Internet and Google Earth, maps are available before leaving on the trip. (See my post on Inner Workings of Storage which discusses how Google Earth works.)
I like using MapQuest, available online at [mapquest.com], and have not yet looked into the similar systems from Google or Yahoo. I map out each leg of my trip that involves driving, walking or trains. These are oftenairport-to-hotel, hotel-to-meeting, meeting-to-airport. Having a feel for the time and distances between locationshelps choose hotels and restaurants, when to leave, and so on.
I even use MapQuest in Tucson. Recently, a route I generated to visit a friend across town took into accountconstruction on Highway I-10 that has been going on for a while, where 8 miles of on-ramps are closed, and routed me around this mess accordingly. This is one key advantage over a static map, either a paper map, or downloaded from Google Earth.
While MapQuest may not always choose the "best" route, it always finds "a route" that works, and generally works for me.
For other reviews of MapQuest, see [Cartography, Cnet's Troy Dreier,EZ Driving, and Misha on HubPages].
A few problems with a MapQuest print-out I have found are:
- It is on paper, which could impact driving, as I have to look away from the road to look at the instructions.
- If it can't find a specific address, it provides generic instructions, and often, this involves airports.
- It often starts with "Head Northeast...", so unless you brought your compass, or can tell what direction you are pointing from Sun, Moon or stars, you may end up leaving in the wrong direction.
Recently, I checkmarked the "Request NeverLost" box on my Hertz Gold profile, and now I seem to get NeverLost innearly every rental. The system is based on the[Global Positioning System] set of satellites,complemented by a CD-based street information and yellow pages data for US and Canada, stored in the trunk.
The NeverLost system knows which way the car is oriented, can tell which direction you are driving, and tell youwith voice prompts to be in the left lane, right lane, and when to make left and right turns. No need for a compassor any knowledge of which way is North, East, West or South.
I also like that it gives you three choices for route: (a) Shortest time, (b) Most use of Highways, and (c) Least use of Highways. This came in handy when I was in Toronto last week. Apparently, the 407 Highway had recently implementedan Electronic Toll Road (ETR) which bills based on license plate. While this system is fine for residents, it isnot designed for rental car companies. Hertz left a note in my car warning me NOT to use the 407 highway, or I wouldbe charged an $8.50 dollar penalty. I chose "Least use of Highways" and proceeded to tour the city of Toronto for90 minutes from the Pearson Airport to my hotel in Markham, a trip that would have only taken 20 minutes otherwise.
Once you enter your destination street address, it can estimate the distance to get there. This is not a quick process, as there is no keyboard, you have to enter each letter using up/down/left/right keys. You can enter thename of the street, hotel or restaurant. To find "Sal Grosso" restaurant in Smyrna, it was at 1927 Powers Ferry Road,but NeverLost said that Powers Ferry only went from 2750-6350. I had to select 2750 and then hope to be close enough.
In Dallas, I tried to find "P. F. Chang's" restaurant, and you have to make sure that the periods and spaces are entered exactly. I ended up looking for restaurants in Grapevine, Texas, and then just going through the list ofall that start with the letter "P".
Another issue is that sometimes it takes awhile to find the satelites in the sky. I get the car started, I hit theenter button to get the NeverLost started, enter the address, and then it starts looking for satellites? Why doesn'tit look for satellites while you spend 3-5 minutes trying to enter the street address?In my case, I take out my MapQuest print-out, head in the right direction, and hope that NeverLost catches upeventually, in time to help me get to the final location.
It is not clear how often Hertz updates the CDrom that contains the street and yellow pages data. About 30-40 percent of the time, it can't find the street address I am looking for, and I have to be creative on howto get me in the general area.
Part of the problems is that I have not read the entire instruction manual, and do not have time to learn itwhen I am in the car driving. I might have to put this on my reading to-do list before my next trip. Some ofmy other colleagues have purchased their own GPS-based systems, like those from Garmin or Magellan, so that theyalways have it available, and they always know how to use it. This has the advantage that you can use it when walking around, or in your own car when you are home, as well.
See the [Official Hertz NeverLost website] for more information.or here for other reviews from[James Martin, and [Thom Hogan].
Despite these few problems, I am impressed on the innovations involved to make this all happen. All of the mapping information was stored, transmitted, searched, and then plotted in a manner that provides specificinformation that you need to get the job done. For now, I will probably use a combination of these to planand travel on my business trips. Wouldn't it be nice if other areas in your life had this kind of support?

In North America, today marks the start of the "Give 1 Get 1" program.
|Children using the XO laptop|
I first learned from this when I was reading about Timothy Ferriss' [LitLiberation project] on his [Four Hour Work Week] blog, and was surfing around for related ideas, and chanced upon this. I registered for a reminder, and it came today(the reminder, not the laptop itself).
Here's how the program works. You give $399 US dollars to the "One Laptop per Child" (OLPC)[laptop.org] organization for two laptops: One goes to a deserving child ina developing country, the second goes to you, for your own child, or to donate to a localcharity that helps children. This counts as a $199 purchase plus a $200 tax-deductible donation.For Americans, this is a [US 501(c)(3)] donation, and for Canadians and Mexicans, take advantage of the low-value of the US dollar!
If your employer matches donations, like IBM does, get them to match the $200donation for a third laptop, which goes to another child in a developing country. As for shipping, you pay only for the shipping of the one to you, each receiving country covers their own shipping. In my case, the shipping was another $24 US dollars for Arizona.No guarantees that it will arrive in time for the holidays this December, but it might.
To sweeten the deal, T-mobile throws in a year's worth of "Wi-Fi Hot Spot"that you can use for yourself, either with the XO laptop itself, or your regular laptop, iPhone, or otherWi-Fi enabled handheld device.
National Public Radio did a story last week on this:[The $100 Laptop Heads for Uganda]where they interview actor [Masi Oka], best known from the TV show ["Heroes"], who has agreed to be their spokesman.At the risk of sounding like their other spokesman, I thought I would cover the technology itself, inside the XO,and how this laptop represents IBM's concept of "Innovation that matters"!
The project was started by [Nicholas Negroponte] from [MIT University] as the "$100 laptop project". Once the final designwas worked out, it turns out it costs $188 US dollars to make, so they rounded it up to $200. This is stillan impressive price, and requires that hundreds of thousands of them be manufactured to justify ramping upthe assembly line.
Two of IBM's technology partners are behind this project. First is Advanced Micro Devices (AMD) that providesthe 433Mhz x86 processor, which is 75 percent slower than Thinkpad T60. Second is Red Hat,as this runs lean Fedora 6 version of Linux. Obviously, you couldn't have Microsoft Windows or Apple OS X, as both require significantly more resources.
The laptop is "child size", and would be considered in the [subnotebook] category. At 10" x 9" x 1.25", it is about the size of class textbook,can be carried easily in a child's backpack, or carried by itself with the integrated handle. When closed, it is sealedenough to be protected when carried in rain or dust storms. It weighs about 3.5 pounds, less than the 5.2 pounds of myThinkpad T60.
The XO is "green", not just in color, but also in energy consumption.This laptop can be powered by AC, or human power hand-crank, with workin place to get options for car-battery or solar power charging. Compared to the 20W normally consumed bytraditional laptops, the XO consumes 90 percent less, running at 2W or less. To accomplish this, there is no spinning disk inside. Instead, a 1GB FLASH drive holds 700MB of Linux, and gives you 300MB to hold your files. There isa slot for an MMC/SD flash card, and three USB 2.0 ports to connect to USB keys, printers or other remote I/O peripherals.
The XO flips around into three positions:
Standard laptop position has screen and keyboard. The water-tight keyboard comes in ten languages:International/English, Thai, Arabic, Spanish, Portuguese, West African, Urdu, Mongolian, Cyrillic, and Amharic.(I learned some Amharic, having lived five years with Ethiopians.)There does not appear be a VGA port, so don't be thinking this could be used as an alternative to project Powerpoint presentations onto a big screen.
Built-in 640x480 webcam, microphone and speakers allow the XO to be used as a communication device. Voice-over-IP (VOIP) client software, similar to Skype or [IBM Lotus Sametime], is pre-installed for this purpose.
The basic built-in communication are 802.1g (54Mbs) that you can use to surf the web usingthe Wi-Fi at your local Starbucks; and 802.1s which forms a "mesh network" with other XO laptops, and can surf theweb finding the one laptop nearby that is connected to the internet to share bandwidth. This eliminates the need to build a separate Wi-Fi hub at the school. There are USB-to-Ethernet and USB-to-Cellular converters, so that might be an alternative option.
Flipped vertically, the device can be read like a book.The screen can be changed between full-color and black-white, 200 dpi, with decent 1200x900 pixel resolution. The full-color is back-lit, and can be read in low-lighting. The black-white is not back-lit, consumes much less power, andcan be read in bright sunlight. In that regards, it is comparable to other [e-book devices], like a Cybook or Sony Reader.
Software includes a web-browser, document reader, word processor and RSS feed reader to read blogs.The OLPC identifies all of the software, libraries and interfaces they use, so that anyone that wants to developchildren software for this platform can do so.
- Game mode
With the keyboard flipped back, the 6" x 4.5" screen has directional controls and X/Y/A/B buttons to run games. This would make it comparable to a Nintendo DS or Playstation Portable (PSP). Again, the choice between back-lit color,or sunlight black-white screen modes apply. Some games are pre-installed.
So for $399, you could buy a Wi-Fi enabled[16GB iPod Touch
] for yourself, which does much the same thing, or you can make a difference in the world.I made my donation this morning, and suggest you--my dear readers in the US, Canada and Mexico--consider doing the same.Go to [www.laptopgiving.org
] for details.
I'm in Atlanta today, on my way back to Tucson, but wanted to talk about IBM's entry-level iSCSI offerings, based on comments on this week's discussion about Dell's acquisition of EqualLogic.
Analysts were quick to comment on this when the news broke.Tony Asaro gave his take on [Dell's Logic - The Storage Market is No Longer Equal], and Steve Duplessie writes [Dell Just Bought N.H.’s Tech Sector]. The last time I remember Steve talking about EqualLogic, [Catching Up], he had the funniestquote:
"EqualLogic didn’t get 2,000 customers because people were dying to use iSCSI. It got them because it built systems that scale dynamically and because a system the size of Montana can be managed by someone as clueless as my ex-wife."
As with any acquisition, people might be asking if this is a "match made in heaven" that makes strong business sense,or another HP-Compaq debacle. Back in September, I posted [Supermarkets and Specialty Shops] to explain how the storage marketplace has two market segments. Internally, IBM distinguishesbetween "clients" and "customers". Clients are those that buy services and complete solutions from a one-stop systems vendor, such as IBM, HP, Sun, or Dell, or systems integrator like IBM, CSC or EDS. Customers are those that buy products and components, from the systems vendors I just mentioned, as well as from individual specialty shops, like EMC, HDS, or NetApp.
To reach the growing "supermarket" segment, specialty shops are dependent on systems vendors to OEM or resell their kit: EMC disk through Dell, HDS disk through Sun and HP, NetApp through IBM. Until now, EqualLogichad to make their living as a "specialty" shop, but iSCSI appeals more to SMB than large enterprises, andSMB tend to be in the "supermarket" segment, so they partnered with Sun. Here is the timeline of this likely awkwardand strained relationship:
I am not surprised that I haven't seen anything in the blogosphere yet from HP, Dell or Sun. I suspect this news meansthat Sun won't be reselling Dell's EqualLogic boxes anymore, and perhaps there is nothing more for Sun bloggers Randy Chalfant or Nigel Dessau to add to that. HP and Dell are practically non-existent in the storage blogosphere, so I didn't expect much from them either.
I did, however, expect EMC to put in their spin, given that Dell resells EMC disk, and accounts for perhaps 15% of their revenues.Now that Dell has multiple offerings, they will be instructing their channel reps when to lead with EqualLogic versus when to sell EMC, for now, until 2011, at which point may simplify their storage sales model to just EqualLogic. I don't know if Dell would do that in 2011. Depending on how quick the decline happens, EMC may have to increase the pricesof their gear, or cut into their development budgets, to make up for this loss.
I started this post because of a comment from EMC blogger Chuck Hollis, who speculates how this will impact[Dell, EqualLogic and EMC].In that post, he expresses his opinion (which I will put into a different color):
"Speculation is pretty evenly split. Neither HP nor IBM have a good, entry-level iSCSI product."
If he had left out the word "good", then that would just be a false statement, but by adding the word "good" reduces this to merely an opinion of IBM products that I disagree with. (I have no experience with whateverHP sells in this category, nor talked to any customers about their experiences, so will neither agree nordisagree with Chuck's opinion of the HP half of his statement). As for the term "Entry-level", this is fairly well defined by analysts as a storage system under $50,000 US Dollars. Actually, IBM has three good offerings.
Our basic, lowest-price model is the IBM System Storage DS3300, which does iSCSI only, like the EqualLogic offerings. This supports both SAS and SATA disks, and can attach to our System x and System p server product lines.
Our smallest model of our fancier IBM System Storage N series not only supports iSCSI, but also CIFS, NFS,HTTP, FTP, and FCP protocols, what we call "Unified Storage". The iSCSI feature is included at no additional charge, and small customers can start with this, then scale up to larger N3600, N5000 or N7000 models, andadd more protocols and software features, as their business grows.
Our next larger model, but still entry-level, is the N3600. Since the N series supports a unified multi-protocolplatform, with features like SnapLock for regulatory compliance and SnapMirror for remote disk mirroring. The IBM System Storage N series easily replaces any mix of EMC "C-boxes": Centera, Celerra, and CLARiiON.
Both the DS3300 and the N series support the various Business Applications I have discussed this week, Microsoft Exchange, Lotus Domino, SAP, Oracle, Siebel, JD Edwards and PeopleSoft. N series offers SnapManager for variousapplications to make the business value even that much better.
Chuck speculates that Dell did this to compete better against rival HP, but that doesn't make sense, sincehe feels HP didn't have much to offer in this space. Perhaps Dell did this to competebetter against IBM, the number one vendor in storage hardware, according to IDC. Looking at what IBM andNetApp have to offer, Dell may have realized that they didn't have competitive disk systems from their resellingrelationship with EMC, looked elsewhere and found EqualLogic. Meanwhile, EqualLogic probably felt that Sun wasgoing out of business, or not yet fully supportive of IP SAN environments, and decided to ["switch horses midstream"].
For more about the DS3300 or N series, see my [Announcement Recap of October 2007] or visit our [www.ibm.com/storage] website.

Continuing this week's theme on Enterprise Applications, today I will cover Oracle.
IBM is Oracle's number #1 integration partner, and has the leading market share, nearly 40 percent, for IT hardware running Oracle applications. In the coopetition category, Oracle's databases competes against IBM's DB2 database offerings, and Oracle'sapplications compete against SAP's set of Enterprise Apps. While SAP offers its own internal database, most production SAP environmentsuse either an Oracle or IBM database instead. Comparing license revenues, Oracle's application side earns roughly 70 percent of the amount SAP applications earn.
To compete against SAP, Oracle has been on a spending spree of acquisitions. This includes PeopleSoft, Siebel, Hyperion, Agile, and JD Edwards.IBM can help with all of these applications, and many clients continue to use IBM DB2 as the underlying database, rather than switching over to Oracle database. For example, IBM has sizing tools to help identify the right amount of servers and storage based on "best practice" experience.
- Server Platforms
Oracle's database uses a number-letter combination. "9i" was Version 9, "i" for Internet. "10g" and "11g" are versions 10 and 11, "g" for Grid. Most of the Oracle customers I deal with are still on 9i or 10g. The 11g releaseis supported on Linux and Windows, with the other platforms to be delivered in a staged approach.
Alternatively, most run also on AIX on System p, and Linux/Windows on System x. For System i customers, the Oracle supports its [JD Edwards World] andJD Edwards Enterprise One natively on i5/OS, the other applications can run under an AIX LPAR on an System i server.
While some of my readers cringe everytime I mentioned benchmarking, IBM has the top benchmarks for Oracle 10g database, [Oracle e-Business Suite], JD Edwards and PeopleSoft.
As with SAP, it is possible with Oracle to run a front-end application on one server platform, and theback-end database on a different server platform. Many of IBM's largest customers run the front-end onAIX or Linux, and then use z/OS on System z for the back-end database.
Oracle has implemented a "Scale-Out" approach called Real Application Clusters [RAC],pronounced same as "rack", which I discussed before [Similar Sounding Storage Speech].Several servers can act as an "application cluster" to access a common database. This approachallows customers to use a bunch of x86 servers instead of a bigger System p or System i machine. Additional processor capability can simply be added into the "application cluster" as needed.
IBM and Oracle are both staunch proponents of Linux. Oracle offers theirOracle Enterprise Linux support program.In this support program, Oracle will offer support service contracts for Red Hat Enterprise Linux (RHEL) corporatecustomers.This could explain why Oracle decided to support[Linux first]on its new 11g database, rather than Windows.
- What's New
To deal with all of their acquisitions, Oracle has announced its Applications Unlimited strategy. Inthis strategy, the Oracle Fusion middleware will support all of Oracle'sapplications, including JD Edwards, PeopleSoft, and Seibel. This is good for IBM, as it will simplify IBM's testing of server and storage platforms for its Oracle clients.
To support pre-sales efforts, IBM and Oracle have formed the IBM Oracle International Competency Center,[IOICC

Continuing this week's theme on Enterprise Applications, I thought that since I mentioned Lotus Notes in my discussion ofSAP yesterday, that I would cover Microsoft Exchange today.
IBM and Microsoft is the ultimate example of "Coopetition". Both companies develop popular operating systems. Microsoft's "Xbox 360" gaming console uses IBM processors. Microsoft Exchange and IBM Lotus Domino are the Coke-and-Pepsi dominant players in the email marketplace, with Microsoft slightly in the lead, as seen on this graph[Lotus Notes/Domino marketshare growing] from fellow IBM Lotus blogger Alan Lepofsky.And now, Microsoft is getting serious about participating in the storage software business, with its strong support for iSCSI and its SharePoint product. For this post, I will focus just on email.
For those not familiar with both Microsoft and IBM products, I offer the simple cheat-sheet below:
Microsoft Outlook (client)::IBM Lotus Notes (client)
Microsoft Exchange (server)::IBM Lotus Domino (server)
- Server/Storage Considerations
Email has become the primary collaboration tool for most businesses, raising it to the level of "mission-critical".Microsoft has introduced its new Exchange 2007 to replace the existing Exchange 2003. Here are the key differences:
|Exchange 2003||Exchange 2007|
|Windows 2000 or 2003||Windows 2003|
|Runs on 32-bit x86||Requires 64-bit EM64T or AMD64, but Itanium IA64 not supported|
|Two(2) server roles||Five(5) server roles|
|Edge Server Role for combating SPAM|
|Unified Messaging services to combine voicemail, email, fax|
|5 storage groups||50 storage groups per server on Enterprise edition|
|5 databases||50 databases per server on Enterprise edition (max 5 per storage group)|
|NAS or NTFS-formatted block disk||NTFS-formatted block disk recommended|
Obviously, Exchange only runs on Windows operating system. The change from 32-bit to 64-bit means that many Exchange 2003 customers have not yet migrated over, and perhapsnow is a good time to point out alternative email servers on more reliable operating system platforms.For example, in addition to Windows 2003, Lotus Domino runs on IBM AIX, Linux on x86, Linux on System z, Sun Solaris, i5/OS on System i, and z/OS.
Another Linux alternative to Microsoft Exchange is Bynari InsightServer, which allows you to use your existing Windows-based Microsoft Outlook clients, swapping out only the server. This approach can be used when consolidating Windows servers to Linux virtual images on System z mainframe.Linux desktops can run [Ximian Evolution] to attach to either Bynari server, or Windows-based Microsoft Exchange server.Linux Journal offers a few articles on this:[Understanding and Replacing Microsoft Exchange, andExchange Functionality for Linux].
As with [Exchange 2003 editions], the new Exchange 2007 comes in both ["Standard" and "Enterprise" editions]. With all the newroles supported, you now can limit your "Mailbox Storage Server" role as Enterprise, and have the other roles, likeEdge and Hub, as simply "Standard" instead. Enterprise is about 5x more expensive than Standard, so that can makea difference.With Exchange 2003, the big difference was that "Standard" supported only 16GB, versus 16TB with "Enterprise",making "Standard" impractical for all but the smallest company. In the new Exchange 2007, both Standard and Enterprise support 16TB.
Exchange 2007 is also less IOPS-intensive. Thanks to 64-bit addressing, it generates about 75 percent fewer IOPS than Exchange 2003 for comparable configurations. This is good becauseaccording to a 2006 Radicati Group survey, the average corporate employee gets 84 emails per day, averaging 10MBdaily ingestion, and this is expected to grow to 15.8MB daily ingestion by 2008. The number of mailboxes worldwideis growing at a rate of 16 percent per year.
IBM System Storage is a Microsoft Gold certified partner, and participates in Microsoft's Exchange Solution Reviewed Program [ESRP].Both IBM DS8000 and DS4000 series are certified under this program, using a testbed called Jetstress.Those considering IBM System Storage N series can use Exchange 2007 with NTFS-formatted LUNs via FCP or iSCSIattachment.
- Backup and Business Continuity
Back in 2003, the Meta Group found that 80 percent of organizations surveyed felt access to email was more importantthan telephone service, and that 74 percent believed being without email would present a greater hardship thanlosing telephone service. These percentages are probably higher today, with websiteslike ["Crackberry.com"] to cater to those addicted to theirRIM Blackberry hand-held devices.
IBM Tivoli Storage Manager can provide backup and recovery support for Microsoft Exchange.TSM for Mail supports both Microsoft Exchange and Lotus Domino. TSM for Copy Services can use MicrosoftVolume Shadow Copy Services (VSS) interfaces. I blogged about this before, back in June[Exchange 2003 VSS Snapshot Backup Whitepaper], and now there TSM has support for Exchange 2007 as well.
Interestingly, Exchange 2007 has some built-in"Business Continuity" features. Of the ones below, Standard edition has LCR only, Enterprise edition gives you the full set.
- Local Continuous Replication (LCR):In this approach, a single server ships update logs from the active storage group on one disk system over to a passivecopy on a secondary disk system, presumably within 10km FCP distance. These logs can then be forward-applied to thepassive copy. This is sometimes called "database shadowing".
- Cluster Continuous Replication (CCR):This is based on two servers in an active/passive MSCS cluster. First server is attached to the primary disk system,and ships logs to the passive copy attached to the second server.
- Standby Continuous Replication (SCR):For the MSCS cluster-averse customer, SCR is based on two independent servers that are in two locations. In the event of failure on thefirst, scripts can be run to switch over to the second server. Each server has its own disk system.
- Single Copy Clusters (SCC):This is for customers who have existing systems, but not recommended for new customers. An MSCS cluster, where both active andpassive servers are connected to the same single disk system. The disk array can be a single point of failure (SPOF) in this environment.You could mitigate risks by using IBM's disk mirroring in this situation, but then you are left coordinating those copies with new servers at the remote location.
- Archive Support
It is estimated that as much as 75 percent of a company's intellectual property (IP) can be found somewhere in their email repository. Email is often requested in lawsuits and regulatory investigations. According to the Workplaceemail IM & blogging 2006 survey by AMA and the ePolicy Institute, 24 percent of organizations have be subpoenaed by courts and regulators, and another 15 percent have gone to court in lawsuits triggered by employee emails.
New regulations now mandate that emails are archived, protected against tampering and unauthorized access, and kept for a specific amount of time, or until certain conditions are met. According to a 2004 CSI and FBI Computer Crime and Security survey, 78 percent of organizations were hit by viruses (the rest must have been running Linux, AIX, i5/OS or z/OS!)and 37 percent reported unauthorized access to confidential information.
IBM offers software to archive emails. IBM CommonStore software supports both Microsoft Exchange and Lotus Domino.For SMB customers, we made things easier with the [IBM CommonStore eMail Archiving Preload Solution], an appliance which I mentioned in [Day 2 Storage Symposium].
- What's Next
According to Gartner, over 60 million people will be doing some form of telecommuting, so access Microsoft hasbeen working on extending the reach of email beyond Outlook client. There is now "Outlook Web Access" thatprovides browser-based access, "Outlook Mobile" to provide text access from cellular phones, and even "Outlook Voice Access" which allows you to listen to your emails from any phone. These are all part of the new Unified MessagingServices feature.
Microsoft is also teaming up with SAP, with a new offering called Duet. See the [SAP and Microsoft Introduce Duet] press release for more details.
It might be a while before all these are commonly deployed, but at least it is something to look forward to!

Continuing this week's theme on Enterprise Applications, I will talk about [SAP
The history of SAP is fascinating. Back in 1972, five IBMers noticed that IBM wasn't leveragingits internal accounting/inventory software package. They asked if they could buy the rights to it, leave IBM to form their own company to fix it up, and sell it as their own. Since IBM had decided not tobe in the enterprise applications business any longer, they approved. These guys renamed the software to "Realtime Data Processing/1" or just R/1 for short, andformed Systemanalyse und Programmentwicklung AG. In 2005, they renamed this to Systeme, Anwendungen, Produkte in der Datenverarbeitung AG,which is German for "Systems, Applications, and Products in Data Processing, Inc.", withSAP AG as the preferred abbeviation (the AG here is justthe German version of "Inc.").
R/1 became R/2, then R/3, and today is now called the SAP ERP forthe SAP Business Suite, although many still call it R/3. Other popular Business Suite components includeCustomer Relationship Management(CRM), Product Lifecycle Management (PLM), and Supply Chain Management (SCM),and Supplier Relationship Manager (SRM).The architecture had evolved in this time frame, separating out the application components from a base platform product line called NetWeaver, similar to IBM WebSphere Application Server (WAS). Other ISVs or in-house developers can build their applications directlyonto the NetWeaver base platform, creating a form of eco-system of software applications.
Today, SAP is now the fourth largest software company (behind Microsoft, IBM and Oracle) employing over 42,000 employees worldwide,and is considered the leading global vendor of Enterprise Application software, generating over $14 billiondollars in revenue each year.
- Server Platforms
SAP runs on all of IBM's major operating systems and server platforms, so it makes sense for IBM to continue its strong ties to SAP. Together, we formed the IBM SAP International Competency Center[ISICC], in Waldorf, Germany,where SAP has its headquarters. I have been to Germany and visited with the folks from the ISICC.Of my 17 U.S. patents, several were for a feature called z/OS DFSMShsm "Fast Replication" that was requested by SAPat one of these meetings. This featuretakes advantage of IBM System Storage DS8000 FlashCopy to make instantaneous backups of an SAP environment built on DB2 for z/OS databases. For more details read the [IBM Redbook: Fast Replication].
The #1 UNIX platform for SAP is IBM's AIX operating system that runs on System p servers. Some of our customers create a[Composite Application] by havingthe SAP front-end application server run on AIX, and use z/OS to host the SAP DB2 databases. Thisallows you to take advantage of DFSMShsm Fast Replication on System z, with the number-crunching power of theSystem p server.
Combining IBM server and storage is a winning combination for SAP performance as well, as evidenced by this[New IBM server achieves championship benchmark results] press release.
Last year, IBM introduced [Lotus Notes 7 access to SAP solutions],which has since been enhanced with Lotus Notes 8 support of Composite Applications, building on IBM and SAP'smutual efforts to get customers to adopt [Service Oriented Architecture (SOA)] and Java.
- Server/Storage bundles
What's most exciting to me about SAP is that for every dollar spend on IT hardware to support an SAP application,60% is for storage, and 40% for servers. Therefore, buying both from IBM is simpler and easier than shoppingfor these separately.
[Business Intelligence], abbreviated BI, attempts to evaluate and correlate data across many different business applications, to help executives make business decisions.An exciting development is [IBM Systems forSAP Business Intelligence Accelerator]. These are pre-installed, pre-configured server/storagebundles in four ["T-shirt"] sizes, based on 500-byte rows:
- Small, 10 user sessions, and 120 million rows
- Medium, 20 parallel user sessions, and 250 million rows
- Large, 50 parallel user sessions, and 500 million rows
- Extra Large, 100 parallel user sessions, and 1 billion rows
The "Accelerator" provides a performance boost by managing large queries in memory. SAP blogger Nenshad Bardoliwalla in his Bardoli Blog explains why [the future is in memory-based data warehouses].
IDC Insight has an opinion paper titled [SAP Business Intelligence Accelerator: A High - Performance Analytic Engine for SAP NetWeaver Business Intelligence by Dan Vesset.
- Backup and Archive Support
IBM Tivoli Storage Manager (TSM) was the first product to certify to SAP's BC-BRS interface for copy/mirror/backup/restore. IBM provides additional support with TSM for SAP, TSM for Databases, andTSM for Advanced Copy Services (ACS). TSM for ACS supports the use of FlashCopy on SVC, DS8000, DS6000, and ESS; as well as SnapShot on the IBM System Storage N series.
IBM's recent push into the Archive and Compliance space offers[IBM CommonStore for SAP],which acts as an "archive file manager" between you SAP application and your archive repository, such asthe IBM System Storage DR550, DR550 Express, N series, and tape.
- What's Next: SMB and SaaS
Since SAP has saturated the market for medium and large size businesses, IBM is now focused on helping theSMB customer base. The majority of these are expected to deploy SAP on x86 platforms running Linux orWindows. For smaller companies, SAP has their "Business All-in-One" for companies with 100-500 users,and "Business One" for companies with less than 100 users. Note: not every employee may need to use SAP,so larger companies may have only a subset of their employees actually using the SAP system and find thesesmaller offerings a good fit.
Nicholas Carr on his Rough Type blog writes:[has SAP unleashed a cannibal?],referring to SAP's new "Business ByDesign" Software as a Service (SaaS) offering to compete againstSalesforce.com business model. Rather than installing and maintaining the SAP software yourself, youinstead pay SAP on a per-user/per-month basis to use their systems remotely. The reference to cannibalism comes from the IT slang "eat your ownchildren", the notion that IT companies may introduce a new offering that eats away at future sales of theexisting product set.

I am in Toronto, Canada. It is a lot cold and rainy here, worse than last week in Seoul, Korea.This looks like a slow news week, so slow that the only news here in Canada is the possibility of anew 5-dollar coin. I thought I would make this week's theme about enterprise applications.
IBM doesn't make these applications anymore, we have decided to focus on our core strength, to be the best IT platform to run other people's applications. This means being the best IT systems, software and services company. However, many of the companies that make enterprise applications are both cooperate and compete against parts of IBM, what we call "coopetition".
Let's take a look at some acronyms in this space:
"Enterprise Resource Planning" represents all the basic applications that business need to run theirbusiness, including: finance, accounting, human resources, and manufacturing. The focus here is to streamline operations and make the workforce more productive. Before IBM, I ran my ownsoftware development company, Pearson Kurath Systems, and we developed ERP applications for clients oneby one, customized to their industry requirements.
"Customer Relationship Management" or sometimes "Client Relationship Management" help companies identifyand retain their customer base. Focus here is to increase customer satisfaction and loyalty.
"Supply Chain Management" help track supply and just-in-time inventory demand, sharing the information withkey suppliers and distributors. The focus is to manage inventories down to nothing, and improve speed to get products out to market.
"Business to Business" refer to procurement, purchase orders, and collecting payments over the internet.One of my pet peeves are acronyms that use "2" to mean "to" and "4" to mean "for".
"Human Capital Management" deals with managing costs of Human Resources (HR) and coordinating servicesfrom outside organizations.
"Knowledge Management" refers to sharing and collaborating information. This is not just email and instant messaging, but also online calendaring, experience repositories, client case studies, and anecdotes.
This week I will cover applications that address these, and how they relate to storage.

IBM announced the industry's first corporate-led initiative to enable clients to earn energy efficiency certificates for reducing the energy needed to run their data centers.For the first time, this provides a way for businesses to attain a certified measurement of their energy use reduction, a key, emerging business metric. The certificates can be traded for cash on the growing energy efficiency certificate market or otherwise retained to demonstrate reductions in energy use and associated CO2 emissions. The Efficiency Certificates initiative engages Neuwing Energy Ventures, a leading verifier of energy efficiency projects and marketer of energy efficiency certificates.
How it works:
- The Neuwing Energy assessments are a two-part evaluation to 1) determine the initial energy draw from the data center or IT equipment identified for consolidation based on industry accepted energy estimates for the servers in use and the power and cooling profiles of the data center, and 2) a second review of energy draw after steps are taken that are designed to reduce energy consumption.
- Neuwing Energy will issue customers an Efficiency Certificate for the total megawatt-hours of energy no longer needed to power and cool their data center or operate IT equipment. Neuwing Energy will keep a portion of each customer's earned certificates or charge a per MWH saved fee in exchange for the assessment.
- Customers can trade earned Efficiency Certificates on the energy efficiency certificate market or they can retain their certificates, using them to demonstrate reductions in energy use and associated CO2 emissions.
IBM intends to make the Efficiency Certificates program available across its entire line of server and storage offerings.
Here is the full Press Release.

I'm following theadvice of Tim Sanders, who reminds us ["Don't let the Wookie always win"
In this case, it is not chess pieces, but FUD being slung around like mud between vendors. EMC blogger Chuck Hollis' post [Products vs. Features] correctly pointsout that IBM has invented most nearly everything useful in IT, and sadly a few things we wish we hadn't.Gene Amdahl, who left IBM to start his own company, is credited for coining the phrase describing IBM'sinnovative sales techniques. Wikipedia has a nice write up on the history of[Fear, Uncertainty and Doubt(FUD)].
Nowadays, when you hear "FUD" most storage administrators immediately think of EMC, who have taken this method to anew level of art-form. Take for example two EMC entries from fellow blogger BarryB, on his Storage Anarchist blog:[Not Dead Yet, andPushing Daisies].The first is a reference to a funny scene from a Monty Python movie, and the second one is referring to a terriblenew television program called "Pushing Daisies". (In this show, the main character can bring a dead personback to life for sixty seconds, just long enough to ask a few questions on behalf of his detective friend. He must touch the person again within 60 seconds, or someone else randomly dies instead. I amnot a fan of this concept, and found it a bit morbid and creepy. But I digress.)
It is true I was on vacation the past two weeks, but this was group travel I booked over six months ago before we had the exact dates lined up for our various announcements, and not a last-minute celebration of my recent new job assignment. I got all my assignments for this announcement turned in before leaving for my trip. I never thought of checking with fellow IBM blogger BarryW to make sure that we don't have overlapping vacation schedules, leaving the "blogosphere" unmanned, so to speak, but it is not a bad idea. Fortunately, our IBM PR team was able to make their rebuttal through other means. You can read the recap on Techworld [Marketing Wars by Proxy].
Several astute readers on my blog, however, requested that I add my two cents. Let's take a look at some of BarryB's comments:
...most DS8300's are to this day most frequently bundled as "free" storage with IBM mainframe and server sales.
We just shipped our 15,000th box, so for this absurd statement to be true, more than half would have to be given away as part of a server-and-storage deal?Actually, about a third of our DS8000 sales are sold with servers in the same bundle, and while we do provide discounts from the official list price, that is not the same as "free". The other two thirds are sold into accounts to be used with the existing servers already deployed. So BarryB, your math doesn't work out. (Perhaps you've been taking Hitachi math lessons???)
It is interesting however, that when we do a 4-year TCO comparison, between a normally-discounted DS8000 versus free EMC DMX4 hardware, IBM still has the lower cost, given that most of the price-gouging from EMC happens after the initial sale, through software features, annual Powerpath renewals and MES upgrades. If you are an EMC customer, and you are planning to add more capacity to your DMX, ask EMC to charge you no more than what you originally paid on a dollar-per-GB basis for the initial capacity. That's only fair, right?
...No thin provisioning, or even a commitment to thin provisioning. Just crickets. (Celerra support since Jan 2006...
EMC DMX does not have thin provisioning available today either, so BarryB brings up Celerra, their NAS box? IBM System Storage N series NAS box also has thin provisioning, so if you want thin provisioning you can buy a NAS box from EMC or IBM. Thin provisioning makes sense using NAS protocols, as there are actual commands to "delete a file" that can then free up the related blocks in a thin-provisioned environment. The only way to do this with block-oriented protocols is to get the OS to notify the storage device that blocks can be freed up. As it turns out, IBM's z/OS has such support, which we developed specifically for our thin-provisioning support in our IBM RAMAC Virtual Array disk systems back in the 1990s.For block-oriented devices on most other operating systems, thin provisioning may not be all that it is cracked up to be.
No SATA drives (only DMX-4 supports native SATA-II drives, since Aug’07)
A few people are confused on this. IBM DS8000 has supported FATA for quite some time now, same slower speeds and higher capacities as SATA, but are technically NOT the same as SATA. FATA are designed to provide better protection against vibrational shock, to improve reliability of the drives. IBM felt that if the data was important enough to put on a high-end system, it should get better-than-SATA treatment. If you really want SATA, try our IBM System Storage N series, DS4000 or DS3000 models.
No RAID 6 (DMX-3 has supported multi-dimensional RAID since Q1’07, DMX-4 since Aug'07, ...
IBM N series supports RAID6, but we called it RAID-DP and that confused some people. Same thing, DP stands for Dual Parity, protecting against a double-disk failure. We also just announced RAID6 on our DS4000 series, by the way.
No 4Gb back-end (USP-V since May '07, DMX-4 since Aug’07)
I found this one odd, since BarryB himself in an earlier post explained why 4Gbps back-end made no difference to DMX4 performance in this post [DMX-4 and Oh So Much More
], which I will put into a different color so you can tell it is from a different post:
You may have noticed that there weren't any specific performance claims attributed to the new 4Gb FC back-end. This wasn't an oversight, it is in fact intentional. The reality is that when it comes to massive-cache storage architectures, there really isn't that much of a difference between 2Gb/s transfer speeds and 4Gb/s. Transmit times are really only a tiny portion of I/O overhead, and just don't make that much difference when a massively-cached system is pre-fetching reads, buffering/delaying writes and reordering I/O requests to minimize seek times. Not that 4Gb/s won't help some applications, but most people just won't see any noticeable difference.
In this case, BarryB is right. The IBM DS8000's 2Gbps back-end is not a performance bottleneck. The DS8000 with a 2Gbps back-end is faster than DMX4 with a 4Gbps back-end for business application workloads. EMC doesn't publish SPC benchmarks to deny this, so you will just have to take our word on this.
Still only 1024 maximum disk drives (DMX-3 & 4 support up to 2400 drives, USP-V supports 1152)
I would be curious to see how many customers have more than 1024 drives on any high-end disk array.As we learned back in [Day 2 Storage Symposium
], the average DS8100 has 17.4 TB, and DS8300 has 41.5 TB capacity. Using 500GB drives,that's only 83 spindles. Even with 73GB drives, that's 568 spindles. Plenty of room for growth, so I am notconvinced that higher theoretical upper architectural limits are worth discussing here.
Still only two HARD LPARs (partitions) ..., and even IBM’s mid-tier products support more than 2 storage partitions (in this same announcement)
IBM's two LPARs are TWICE what EMC DMX offers. I don't even know why anyone from EMC would bring this up? While EMC is enjoying their success with VMware, the lack the experience to carry this over to their storage lines. Until EMC offers MORE THAN TWO of any kind of partitions on their high-end offerings, there just is no credibility here. As for our "storage partitions" on our DS4000 line, that is an unfortunate mis-understanding of the press release. On the DS4000, the term "storage partition" is really "LUN masking", dividing up only which disks can be accessed by which hosts, and not dividing up any processor or cache capacity. So this is not the same as any LPAR concept on any other system. For example, a DS4000 with 64 partitions can be attached to 64 hosts, or 64 host-clusters like a Windows MSCS environment or AIX HACMP.
No native Ethernet replication or iSCSI support (Symmetrix has had since 2002)
Again, I found this one odd. On another EMC post, [Vigorous Debates
],Chad Sakac mentions that only 2% of Symmetrix are sold with IP ports, not sure if this is for Ethernet replication, iSCSI attachment, or both (Again, I will use a different color):
On the Symm business (a huge part of EMC’s business – the IP ports are included on 2% of deals. That’s a fact.
Just because engineer can put a feature or function on a box, doesn't mean there is business sense to do so. I would hate for IBM to invest millions of dollars on native iSCSI support, only to have 2% of our DS8000 boxes sold with that feature. Customers who have DS8000 on FC SANs already deployed can easily add iSCSI support either through their SAN switches, or by fronting the DS8000 with an N series gateway. Most customers looking for native iSCSI are the smaller no-SAN-deployed SMB customers, and for them, we have both the DS3300 and the various N series models to choose from.
Well that's my two cents. The DS8000 series remains a strategic part of the IBM System Storage offering matrix, with continued investment in the development, as well as on-going research that we can leverage throughout the IBM company. I would like to read your thoughts on this, post me a comment below.

Well, it is Halloween
back in the USA. I am in Seoul Korea this week, so it is already Thursday, November 1st here, but thought I would comment on Colin Barker's piece in ZDnet
titled[SNW offers the frights
].The article starts out with an oversimplification:
The storage industry is enjoying a boom currently thanks to the requirement for IT managers to keep everything. With the possibility of being sued any time by any company for no good reason at all, everyone is keeping everything, or at least all their data. Result? Loads and loads more kit being bought to the benefit of EMC, IBM, HP and every other supplier with any kind of storage product.
While its true that IBM System Storage grew yet again in 3Q07, exceeding our own internal business model, I would not call this an overall "boom" for the storage industry. While companies are growing in "TB capacity" by 30-50%, this translates only to single digit growth in terms of "Dollar revenues". This is because we continue to make storage with declining dollar-per-GB.
One should not confuse what people do with what people are required to do. I am not a lawyer, but most regulations pertaining to storage of information state that certain records need to be kept for a set amount of time, either a fixed period of years, or based on some event. For example, broker/dealers need to keep emails of their clients for six years after the client closes their brokerage account. After those six years, the records can be destroyed.
Unfortunately, many IT managers look at the laws and come up with the simplest solution: keep everything forever. While this might meet the regulators audit requirements, it does expose their employer to subpoenas for data that should have been deleted, and may not be very cost-effective.
The alternative for many IT managers involves having to leave their comfort zone, and talk to their legal counsel, the lines of business, and try to classify their data, determine a set of policies, and inact some forms of enforcement. This is perhaps the "scary" part of the storage of information, it has grown outside the walls of IT, forcing IT managers to interact with the rest of the business to get their jobs done.
Compliance is the only game in town and that is most certainly where the money is.
Anytime an analyst tells you that something is the "only game in town", they are usually wrong. In this case, IBM has had great success in other areas that are not compliance-related. For example, digital video surveillance (DVS) is being used not only to help reduce shoplifting, but also to help identify patterns in customers perusing through aisles and window-shopping. Identifying what people are interested in has proven effective in moving product displays around to better attract buyers and motivate them to make purchases.
Take, the keynote from Andy Monshaw, general manager of IBM storage, and thus a man who is very much in a position to know. He spent his allotted 30 minutes, or whatever, listing all the security, compliance, threats and related issues that are currently making the jobs of most IT manager a cause for concern. Now, there is an argument that suggests that it is absolutely the right thing to do to frighten IT managers into sorting out their issues. They need shaking up say some. Especially analysts.
I helped develop the content of Andy's SNW presentation, working with his speech writers and graphic artists to make a consistent and coherent message fit in the 25 minutes he was given. The challenge with SNW is that we needed to make this presentation applicable across the entire storage industry, without sounding like an infomercial for IBM offerings.
Some people have compared the storage to the "insurance industry", claiming that backups, remote disk mirroring, continuous data protection and other storage related features are costs that can be compared to insurance you pay to protect your home, business, and other assets. You hope you never have to use it, and complain how much it costs, but when bad things happen, you hope it is the best money can buy.
Unlike Y2K, which was a one-time event that had a specific date of occurrence, the threats and risks mentioned by Andy in his presentation may never happen at all, or in other cases, may happen more than once, without knowing when or where. For the sake of your shareholders, and your stakeholders, it is best to be prepared for these possibilities.
The counter argument says that IT companies just smell the money.
Is this a counter argument? Can IBM not both help customers mitigate their risks, and at the same time, turn a profit? Trust me, you do not want to do business with any storage vendor that is not interested in making a profit. The better ones have incorporated addressing client's most pressing challenges into their strategy. I gave a quick summary of IBM's strategy last August in [Day 1 Storage Symposium].
Helping our clients mitigate risks is just one of IBM's core strengths. If you want to learn more, contact your local IBM Business Partner or storage rep.

Well it's Tuesday, which means its time to look at recent announcements.While I was on vacation last week, IBM made a lot of storage announcements October 23.Josh Krischer gives his summary on WikiBon [October 2007 Review
].Austin Modine of the The Register
went so far as to say that [IBM goes crazy with storage system updates
- IBM System Storage DS8000 series
This is "Release 3" software/microcode upgrades on our existing "Turbo" hardware.
- IBM FlashCopy SE -- Here "SE" stands for Space Efficient. Rather than allocating a full 100% of the space for the FlashCopy destination, you can set aside just a fraction, and this will hold all the changed blocks, similar to whatIBM already offers on the DS4000 series.
- Dynamic Volume Expansion -- In the past, if you needed more space for a LUN, you had to carve out a newer one elsewhere, and then copy the data over from the old to the new, leaving the old LUN around to be re-used or leftstranded. With this enhancement, you can just upgrade the LUN in place, making it bigger as needed, similar to whatIBM already offers on the DS4000 series and SAN Volume Controller. This applies to CKD volumes for the System zmainframe users out there as well.
- Storage Pool Striping -- striping volumes across RAID ranks to eliminate or reduce hot-spots, and provide betterload balancing. Many used SAN Volume Controller in front of the DS8000 to do this, but now you can do it natively inthe DS8000 itself.
- z/OS Global Mirror Multiple Reader -- for System z customers, "z/OS Global Mirror" is the new name for XRC. Thisenhancement improves the throughput of sending updates to the remote disaster recovery location.
- DS Storage Manager enhancements, the element manager software has been enhanced, and is pre-installed on the new IBM System Storage Productivity Center, which I will talk about below.
- Intermix of DS8000 machine types -- this is especially useful to allow new frames to have co-terminating warrantieswith the base units. In other words, as you expand your system, you can ensure that the entire chunk of iron runs outof warranty all at the same time, to simplify your decision making process to upgrade or contract for extended service.
See the [DS8000 Announcement Letter] for more details.
- IBM System Storage SAN Volume Controller 4.2.1
BarryW summarizes the updates in the[Announced SVC 4.2.1] release.If you have problems with the link he provides in his post, here is the [SVC 4.2.1 Announcement Letter].
- IBM System Storage Productivity Center
One of the biggest complaints about IBM TotalStorage Productivity Center is that it is software that needs to beinstalled on its own server, and that this installation process can take a day or two. Why wait? Now you can havea hardware console that has the DS8000 Storage Manager software, SVC Admin Console software, and IBM TotalStorageProductivity Center "Basic Edition" pre-installed. Here are the key features.
- Pre-installed and tested console
- DS8000 R3 GUI integration
- Cohabitation of SVC 4.2.1 GUI and CIMOM
- Automated device discovery
- Asset and capacity reporting, including tape library support
- Device configuration
- Advanced topology viewer
See the[System Storage Productivity Center - Announcement letter] for more details."Basic Edition" can be upgraded to "Standard Edition" to get full functionality.
- IBM System Storage N series
Our "Release 9" applies across the board, from N3000 to N5000 to N7000 series models, includingnew host bus adapters, and the new Data OnTAP 7.2.4 release level.
The Virtual File Manager (VFM) was announced as one of our latest [Storage Virtualization Solutions]. VFMprovides a global namespace that aggregates the file systems from Linux, UNIX, and Windows file servers, as well asN series storage, into a consolidated environment.
See the [N series Announcement Letter] for more details.
- IBM TS7520 Virtualization Engine
IBM's virtual tape library (VTL) for the distributed systems platform, has been enhanced to provide:
- Up to 12TB of disk cache, using 750GB SATA disk.
- F05 Tape Frames installed as TS7520 base units through a 32 port fibre channel switch
- Support for LTO generation 4 tape drives, both as virtual tape drives and as physical tape drives within IBM automated tape libraries attached to the TS7520. This allows you to use Encryption capabilities of LTO4.
See the [TS7520 Announcement Letter] for more details.
- IBM System Storage DS6000 series
The latest 300GB 15K RPM drives are now supported.
- IBM System Storage DS4000 series
This was a software/microcode upgrade release for the DS4000 series.
- RAID-6 support on the DS4700 Express models and the DS4200 Model 7V
- Support for greater than 2 TB volumes on selected supported operating systems
- 8K cache block size
- DS4000 Storage Manager v10.10 increases the number of FlashCopy tasks, remote mirror pairs, and storage partitions.
See the [DS4000 Announcement Letter] for more details.
- IBM System Storage DS3000 series
DS3000 series now supports SATA disk, and can be attached to AIX and Linux on System p servers. This appliesto the DS3200, DS3300 and DS3400 models.See the [DS3000 Announcement Letter] for more details.
- IBM System Storage TS2240
These are LTO4 Half-High drives, which can support encryption.See the [TS2240 Announcement Letter] for details.
Perhaps Austin is right, we might have gone crazy announcing all of this at once.

Well, I'm back from my relaxing vacation in New Zealand and Fiji. Yes, we hada few earthquakes near Milford Sound, several avalanches that blocked some roads, a few power outages, and we walked in a rain storm for three hours after our bus broke down. But overall, it was fun.
This week I am in Seoul, South Korea for various business meetings. The best part is that I am almost already acclimated to the time zone, since New Zealand was GMT+11 and Fijiwas GMT+12, I am hoping that I will adjust fast this week.
South Korea is part of our "BRICK" countries--those emerging markets made up of Brazil,Russia, India, China and Korea that represent IBM's spearhead into the SMB marketplace.[Read More]
