The "Storage Symposium Mexico - 2008" conference was a great success this week!
Day 1 - The plan was for me to arrive for the Wednesday night reception. Eachattendee was given a copy of my latest book[Inside System Storage: Volume I] and I was planning to sign them. I thought perhaps we should have a "book signing" tablelike all of the other published authors have.
Things didn't go according to plan. Thunderstorms at the Mexico City airport forced our pilot to find an alternate airport. Nearby Acapulco airport was the logical choice, but was full from all the otherflights, so the plane ended up in a tiny town called McAllen, Texas. I did not arrive until the morning of Day 2,so ended up signing the books throughout Thursday and Friday, during breaks and meals, wherever they couldfind me!
Special thanks to fellow IBMer Ian Henderson who picked me up from the airport at such an awkward hour anddrive me all the way to Cuernavaca!
All of us, IBMers, Business Partners and clients alike, all donned black tee-shirtswith a white eightbar logo for a group photo with one of those "wide lens" cameras. While we werebeing assembled onto the bleachers, I took this quick snapshot of myself and some of the guys behind me.
I was original scheduled to be first to speak, but with my flight delays, was moved to a time slot after lunch.After a big Mexican lunch, the conference coordinators were afraid the attendees might fall asleep,a Mexican tradition called [siesta], so I wasinstructed to WAKE THEM UP! Fortunately, my topic was Information Lifecycle Management, a topicI am very passionate about, since my days working on DFSMS on the mainframe. With 30percent reduction in hardware capital expenditures, 30 percent reduction in operational costs, and typical payback periods between 15 to 24 months, the presentation got everyone's attention.
Of course, a lot happens outside of the formal meetings. We had a Japanese theme dinner, where we woreJapanese Hachimaki [headbands]with the eightbar logo. For those not familiar with Japanese culture, hachimaki are worn today not so much for the practical purpose to catch the perspiration but rather for mental stimulation to express one's determination. Some students wear hachimaki when they study to put themselves in the right spirit and frame of mind.
Shown here are presenters Mike Griese (Infrastructure Management with IBM TotalStorage Productivity Center),Dave Larimer (Backup and Storage Management with IBM Tivoli Storage Manager), myself, and John Hamano(Unified Storage with IBM System Storage N series).
Day 3 - Wrapping up the week, I presented two more times.
First, I covered IBM Disk Virtualization with IBM SAN Volume Controller. One interesting question was if the SAN Volume Controller could be made to looklike a Virtual Tape Library. I explained that this was never part of the original design, but that if you wantto combine SVC with a VTL into a combined disk-and-tape blended solution, consider using theIBM product called Scale-Out File Services[SoFS] which I covered in my post[Moredetails about IBM clustered scalable NAS].
During one of the breaks, I took a picture of the behind-the-scenes staff that put this together. They had created these huge blocks representing puzzle pieces, emphasizing how IBM is one of the few ITvendors that can bring all the pieces together for a complete solution.
Shown hereare Mike Griese (presenter), Cyntia Martinez, Claudia Aviles, Cesar Campos (IBM Business Unit Executive forSystem Storage in Mexico), and Claudia Lopez. Each day the staff wore matching shirts so that it was easyto find them.
Later, I covered Archive and Compliance Solutions to highlight our complete end-to-end set of solutions.When asked to compare and contrast the architectures of the IBM System Storage DR550 with EMC Centera, I explainedthat the DR550 optimizes the use of online disk access for the most recent data. For example, if you aregoing to keep data for 10 years, maybe you keep the most recent 12 months on disk, and the rest is moved,using policy-based automation, to a tape library for the remaining nine years. This means that the disk insidethe DR550 is always being used to read and write the most recent data, the data you are most likely to retrievefrom an archive system. Data older than a year is still accessible, but might take a minute or two for the tapelibrary robot to fetch.The EMC Centera, on the other hand, is a disk-only solution. It offers no option to move older data to tape,nor the option to spin-down the drives to conserve power. It fills up after the same 12 months or so, and then you get towatch it the remaining nine years, consuming electricity and heating your data center.
I don't know about you, butI have never seen anyone purposely put in "space heaters" into their data center, but certainly a full EMC Centeradoes little else. Both devices use SATA drives and support disk mirroring between locations, but IBM DR550 offers dual-parity RAID-6, and supports encryption of the data on both the disk and the tape in the DR550. EMC Centerastill uses only RAID-5, and has not yet, as far as I know, offered any level of encryption. IBM System StorageDR550 was clocked at about three times faster than Centera at ingesting new archive objects over a 1GbE Ethernet connection.
This last photo is me and fellow IBMer Adriana Mondragón. She was one of my students in the [System Storage Portfolio Top Gun class],last February in Guadalajara, Mexico.She graduated in the top 10 percent of her group, earning her the prestigious titleof "Top Gun" storage sales specialist.
The conference wrapped up with a Mexican lunch with a traditional Mariachi band. I took pictures, but figured you allalready know what [Mariachi players] look like, and I didn't wantto detract from the otherwise serious tone of this blog post! This was the first System Storage Symposium in Mexico, butbased on its success, we might continue these annually.
Last week's focus was on tape libraries, both virtual and real, leading up to our IBM announcement ofacquiring Diligent Technologies. I was focused on HDS blogger Hu Yoshida's post about his conversation with Mark,who was on an expert panel about these topics. Mark discovered that of the top energy consumersin his datacenter, his tape library was in the top five, a surprising result. Hu suggested that switching to a VTL with deduplicationtechnology was a potential alternative, and I pointed to a whitepaper from the Clipper Group that suggested otherwise.
My response was that perhaps Highmark's choice of backup software was poorly written, or that they had set it up with thewrong parameters, and just changing hardware might not be the right answer. I went too far given that I didn't know which software they had, which parameters theywere using, or which tape technology was involved. This came across wrong. I meant to poke fun at Hu's response.I did not mean to imply that Mark and his staff hadmade poor choices, or that they should automatically reject Hu's advice to consider other hardware alternatives.
I have discussed the situation with Mark, and agree that I should know his situation better before offeringsuggestions of my own.
Well, its Tuesday, and that means more IBM announcements!!!
Let's do a quick recap of what was announced for storage:
We now support 1000GB SATA-II drives in the DS4000 series. This is available for the DS4200 model 7V, DS4700, DS4800 as well as the expansion drawers EXP420 and EX810. When I asked our marketing team why we weren't going to say "1TB" like everyone else, they thought 1000GB sounds bigger. I guess I should not have asked that on April Fool's day. For more details, see the IBM press releases for the [DS4200/EXP420and DS4700/DS4800/EXP810].
IBM announced new machine code Release 1.4a for the The IBM Virtualization Engine™ TS7700 virtual tape library for our System z mainframe customers.Various features come with this new level of machine code. See the IBM [Press Release] for more details.
Load balancing across the grid
Host control over the copy of logical volumes on a cluster by cluster basis
Option to gracefully remove an individual cluster from an existing grid
Initial-state reset for TS7700 database for cluster cleanup
Option to upgrade single-cache to dual-cache configuration
Also announced were updates to the 7214 model 1U2. Technically this is not in the IBM System Storage product line,but instead is designed specifically for our System p server line. This is a "media drawer" that allows you to havetape on one side, and optical on the other, in a single enclosure. IBM announced that you can now have DAT160 80GBdrives that is read-write compatible with DAT72 and DDS4 drives, and half-high LTO-4 drives that can read LTO-2 media, and is read-write compatible with LTO-3 media.Read the IBM [Press Release] for details.
Finally, if you are in the United States, Canada or the Carribean, there is a special discount promotionfor tape libraries purchased before June 20, 2008. This includes IBM TS3100, TS3200, TS3310 and TS3500 libraries.See the [Promotion Details] for eligibility.
IBM has added capability to the IBM TotalStorage Productivity Center for Replication. A quick review of the differentoptions for this component.
base Replication (uni-directional from primary to disaster site)
Two-site replication (bi-directional, including failover and failback)
Three-site replication (site awareness for all the copy sessions between all three sites in all situations)
Productivity Center for Replication supported all these levels for DS8000, DS6000 and ESS 800 disk models, butfor SVC it only supported FlashCopy and Metro Mirror for the uni-directional base. IBM announced version 3.4 today that has added support for SVC for Global Mirror (asynchronous disk mirroring) and bi-directional failover/failback. This supports lets you have "practice volumes" that allow IT managers to perform "disaster recovery exercises" without disrupting production workloads.
Also, for the DS8000, there is support for the new Space Efficient FlashCopy and DynamicVolume Expansion features. Here is the IBM
The Productivity Center for Replication server can run on either a Windows/Linux-x86 server or a z/OS mainframe server.The Productivity Center for Replication on System z offers all the same new support for SVC and DS8000, as well asincorporated Basic HyperSwap capability that I mentioned in my post last February[DS8000 Enhancements for the IBM System z10 EC].
Here are the IBM press releases for the TotalStorage Productivity Center for Replication on[Windows/Linux-x86and System z] servers.
I'm at a Business Partner conference today, discussing these announcements and other topics, so need to go back to those festivities.
My IBM colleague Marissa Benekos brought her hand-held video camera to [Storage Networking World] conference in Orlando, Florida.I am not there, as I had a conflict with another conference going on here in Tucson, so am relyingon Marissa to feed me information to blog about.
In this segment, she interviews "booth babe" David Bricker. I've known David a long time,and if you are there at the conference, tell him I sent you to visit him at the IBM booth.
David Bricker shows off some of the IBM System Storage product line at SNWin this YouTube video (2 minutes)
Sadly, I can't be in two places at once. SNW is a great conference to attend!
Fellow blogger and cartoon writer Scott Adams writes in his Dilbert Blog posts about the [Monte Hall problem].Monte Hall was the host of the American game show Let's Make a Deal. Here is an excerpt:
"The set up is this. Game show host Monte Hall offers you three doors. One has a car behind it, which will be your prize if you guess that door. The other two doors have goats. In other words, you have a 1/3 chance of getting the car.
You pick a door, but before it is opened to reveal what is behind it, Monte opens one of the doors you did NOT choose, which he knows has a goat behind it. And he asks if you want to stick with your first choice or move to the other closed door. One of those two doors has a car behind it. Monte knows which one but you don’t."
Mathematically, on your initial choice of doors, you have a 1/3 chance of picking the car, and 2/3 chance ofpicking a goat. But, after you make a choice, Monte knows which door(s) have goats behind them, and selectsone that exposes the goat. If you stay with your initial choice, you still have a 1/3 chance that you win acar, but if you change your mind and choose the other door, your odds double, you have a 2/3 chance of winning.This is not obvious at all to most people, so Scott points people to the [Wikipedia entry] that provides the mathematicaldetails.
What does this have to do with storage?
When you pick a disk system, you are hoping you pick the door with the car. You want a disk system that meets your performance requirements for your particular workload and easy to deploy, configure and manage, with a low total cost of ownership for the three, four or five years you plan to use it.However, with over forty different storage vendors, there are some doors that might have goats. Some vendorshave only 90 day warranties for their software, and I don't know any customers that replace their disk systems that often.
(It was pointed out to me that it was unfair in my last week's post about[Xiotech'slow cost RAID brick], that I singled out EMC offering minuscule 90day warranties for the software needed to run their disk systems. I apologize. I have sincelearned that HDS and HP also shaft their clients with 90 day warranties. Apparently thereare a lot of vendors out there who lack confidence in the quality of their software!)
It would be nice if everyone published all of their performance benchmarks so that you canchoose the right door with the car behind it, but sadly in the storage industry, not everyoneparticipates with industry-standard benchmarks like the[Storage Performance Council].
In other cases, people make their choices based on past decisions. Perhaps someone beforethem chose one vendor over another, and it seems simple enough just to stay with the originalchoice. It is amazing how often people stay with their company's original choice, what we call in the industry the "incumbent vendor", without exploring alternatives.
So, if you bought an EMC, HDS or HP disk system in the last 90 days, it's not too late for you.Tell your local IBM rep that you are afraid you picked the door with the goat, and that you want to change your mind, and choose the other door and go with IBM instead.
You will double your chances of being happier with your new choice!
There is a difference between improving "energy efficiency" versus reducing "power consumption".
Let's consider the average 100 watt light bulb, of which 5 watts generate the desired feature (light), and 95 percent generated as undesired waste (heat). In this case, it would be 5 percent efficient. If you delivered a new light bulb that generated 3 watts of light for only 30 watts of energy, then you would have an offering that was more energy efficient (10 percent instead of 5 percent) and use 70 percent less power (30 watts instead of 100 watts). This new "dim bulb" would not be as bright as the original, but has other desirable energy qualities.
Nearly all of the output of data center equipment results in heat.In The Raised Floor blog [It's Too Darn Hot!], Will Runyon explains how IBM researcher Bruno Michel in Zurich has developed new ways to cool chips with water shot through thousands of nozzles, much like capillaries in the human body. This is just one of many developments that are part of IBM's [Project Big Green]
But what if the desired feature is heat, and the undesired feature is light?In the case of Hasbro's toy[Easy-Bake Oven],a 100W incadescent light bulb is used to bake small cakes. This is generating 95W of desired heat, and onlywasting 5 percent as light (unused inside the oven). That makes this little toy 95 percent energy efficient, butconsumes as much energy as any other 100W light bulb lamp or fixture in your house. With manufacturing switchingfrom incadescent to compact flourescent bulbs, this toy oven may not be around much longer.
While we all joke that it is just a matter of time before our employers make us ride stationary bicycles attached to generators to power our monstrous data centers, 23-year old student Daniel Sheridan designeda see-saw for kids in Africa to play on that generates electricity for nearby schools. [Dan won the "mostinnovative product" at the Enterprise Festival].
Another approach is to improve efficiency by converting previously undesirable outcomes to desirable. Brian Bergstein has a piece in Forbes titled["Heat From Data Center to Warm a Pool"].Here's an excerpt:
"In a few cases, the heat produced by the computers is used to warm nearby offices. In what appears to be a first, the town pool in Uitikon, Switzerland, outside Zurich, will be the beneficiary of the waste heat from a data center recently built by IBM Corp. (nyse: IBM) for GIB-Services AG.
As in all data centers, air conditioners will blast the computers with chilly air - to keep the machines from exceeding their optimum temperature of around 70 degrees - and pump hot air out.
Usually, the hot air is vented outdoors and wasted. In the Uitikon center, it will flow through heat exchangers to warm water that will be pumped into the nearby pool. The town covered the cost of some of the connecting equipment but will get to use the heat for free."
I see a business opportunity here. Next to every data center lamenting about their power and cooling, build a state-of-the-art fitness center for the employees and nearby townspeople. Exercise on a stationary bicyclegenerating electricity, while your kids play on the see-saw generating electricity, and then afterwards thewhole family can take a dip in the heated swimming pool. And if the company subscribes to the notion of a Results-Oriented Work Environment [ROWE],it could encourage its employees to take "fitness" breaks throughout the day, rather than having everyone there in the early morning or late evening hours, leveling out the energy generated.
[Earth Day] is celebrated in many countries on April 22, which marks the anniversary of the birth of the modern environmental movement in 1970. Others celebrate this on the March equinox.
IBM has finally aggregated everything that we are doing around "Green" initiatives onto a single[IBM Green] landing page. This has everything from IBM's own activities as well as what we sell to our clients.
Also, to mark this occasion, IBM held an internal contest for employees to make videos about Earth Day,the environment, and IT's role in making the situation better. The grand prize winner, and 10 secondprize winners, are available on this [IBM Green Contest - YouTube channel].Of these, I liked "New Life for Old Silicon" (shown here on the left).
IBM also developed [Power Up, the Game], which is theEarth Day Network's "official" game for today's festivities. It's a 3-D game created by IBM Research to help save a fictitious planet - the goal being to help students learn about ecology and climate change. This game is also hoped to motivate young students to get interested in math, scienceand technology.Eightbar has a great post [PowerUp - A serious game out inthe wild] discussing this.Here's also a 3-minute[the making of "Power Up, the game" video] to geta behind-the-scenes look.The game is a downloadable Windows client that then connects to the main servers to run.
Normally, IBM only makes announcements on Tuesdays, but today, Friday, IBM announces that it acquired Diligent Technologies. What? I got a lot ofquestions about this, so I thought I would start with this...
When I posted in January that[IBM Acquires XIV],fellow EMC blogger Mark Twomey of StorageZilla fame, sent me a comment:
"Ah now Tony I wasn't poking fun. Indeed I find it fascinating that Moshe who's been sitting out on the fringes for years having been banished for being an obstructionist to EMC entering the mid-market is now back.
Which reminds me what happens with Diligent? There his as well aren't they or has he packed his stake in that in?"
As you might have guessed, I am privy to a lot of stuff going on behind the scenes at IBM that I can't talk about in this blog, and all these rumors in the blogosphere about IBM acquisition of Diligent was a topic I couldn't officially recognize, defend or deny, until official IBM announcements were made.
In his latest post, Mark wonders about[the last Tape and Mainframe sales person on earth]. He recounts my interaction with fellow HDS blogger Hu Yoshia about the energy benefits ofVirtual Tape Libraries. Knowing that we were going to announcement IBM's acquisition of Diligent soon, I thoughtthis would be a worthy exchange, driving up the sales of Diligent boxes (whether you buy them from IBM or HDS).Diligent already had reselling arrangements with HDS, and IBM plans to continue thosearrangements going forward with HDS. As I have explained before in my post [Supermarketsand Specialty Shops], IBM and HDS cater to different customers, so if a customer who wants the best technologyfrom a specialty shop, they can buy IBM Diligent products from HDS, but if they want one-stop shopping, they can buyIBM Diligent directly from IBM or its other IBM Business Partners.
(Perhaps a more tricky situation is that Diligent also had an arrangement with Sun Microsystems, which competesdirectly against IBM as another IT supermarket vendor, but I have not heard how IBM has decided to handle thisgoing forward.)
For more on this intricate mess of interconnected companies, alliances and partnerships, read Dave Raffo's article[Data dedupe dance cardfilling up] over at Storage Soup.
So, let's tackle the first question:
Q1. What will happen to IBM's real tape library business?
Come on! IBM is Number one in tape, we've had virtual tape libraries since 1997 (the first in the industry)and continue to do well in both virtual and real tape libraries. Both provide value to the customer, and bothhave their place as part of the overall "information infrastructure". This acquisition provides yet another choicefor clients on our "supermarket" shelf.
(For those following the ["which is greener"] discussion, the robot of the IBM TS3500 real tape library consumes185W per frame (when moving) and each tape drive consumes 50W (when actively working on a tape). Compared to 13W per SATA disk drive, each 6-drive frame of a TS3500 consumes as much electricity as 37 SATA disk drives. If you are not running backups 24x7, the total KWh per day for your tape library is actually quite less, but as several people have pointed out, there are customers that do run backups 80-90 percent of the time. LTO-4 tapes can hold 800GB uncompressed, and SATA disk are now available in 1TB (1000 GB) size, so you can have fun with your own comparisons.)
Meanwhile, Scott Waterhouse, one of the few people at EMC who understand tape workloadslike backup and archive, takes me to task in his Backup Blog with his post[I want a Red Ferrari].For those who are surprised that anyone at EMC might understand backup workloads, EMC did acquire a company calledLegato, and perhaps Scott came from that acquisition. I've never met Scott in person, but based solely only fromhis writings, he seems to know his stuff and makes strong arguments for using IBM Tivoli Storage Manager (TSM) with deduplication and virtual tape libraries.
While TSM does a good job of "deduplicating" at the client first, backing up only changed data, Scott feels database and email repositories must be backed up entirely each time, which is what happens in many other backup software products. Some clients might have 80 percent database/email and only 20 percent files, while others might have less than 20 percent database/email and 80 percent files, so this might influence whether deduplication will have small or big benefit.If TSM has to backup the entire database, even though little has changed since the last backup, that is where deduplication on a virtual tape library can come in handy. For IBM DB2 and Oracle databases, IBM TSM application-aware Tivoli Data Protection module interface backs up only changed data, not the entire file. Thanks to IBM's FilesX acquisition-- (also coincidently from Israel) --IBM can extend this support now to SQL Server databases as well.However, to be fair, Scott is partly correct, TSM does backup some database and email repositories in their entirety, which is why it is a good idea to have BOTH an IBM virtual tape library with deduplication and Tivoli Storage Manager to handle all cases. This brings us to the next question:
Q2. What will happen to IBM's patented "progressive backup" technology?
IBM will continue to use TSM's progressive backup technology. TSM already works great with Diligent virtual tapelibraries. One example is LAN-free backup. In this configuration, the TSM client writes its backups directly toa virtual or real tape library, over the SAN, and then sends the list of files backed up to the TSM server over theLAN to record in its database. This can greatly reduce IP traffic on your LAN during peak backup periods. For more about this, see the IBM Redbook titled["Get More Out of Your SAN with IBM Tivoli Storage Manager"].
Jon Toigo from DrunkenData asks[Did IBM Do Due Diligence Before Making Diligent Acquisition a Done Deal?] which is probably always a valid question. Unlike XIV, I wasn't part of the Diligent acquisition team, so I can't provide first hand account of the process. I am told that the IBM team did all the right things to make sure everything is going to turn out right.Sadly, many companies that make acquisitions in the IT industry fail to make them work. Fortunately, IBM is one of the few companies that has a great success record, with over 60 acquisitions in the past six years.In the Xconomy forum, Wade Rousch writes[IBM and the Art of Acquisitions]and gives some insight why IBM is different. Jon did not understand why Cindy Grossman, IBM VP of tape and archive solutions, ran the analyst conference call for this announcement, which brings me to the next question:
Q3. What is Diligent virtual tape library going to be categorized as, a disk system or a tape system?
IBM organizes its storage systems based on the host application workloads.Products to address disk workloads (SVC, DS8000 series, DS6000 series, DS4000 series, DS3000 series, N series, XIV Nextra) are in our disk systems group. Storage that appears to host applications like a tape system to address workloads like backup and archive (tape drives, libraries and tape virtualization) are in our tape and archive group. IBM Diligent has two products, one for big workloads and one for medium workloads. Both look liketape systems, so our tape and archive team, who understand tape workloads like backup and archive the best, are obviously the best choice to support IBM Diligent in the mix.
IBM will offer both N series and Diligent deduplication capabilities. For disk workloads, IBM N series offers a post-process deduplication feature at no additional charge. For tape workloads, IBM will now offer an in-line deduplication feature with Diligent Technologies. Different workloads, different offerings.
As with any acquisition, there will be some changes. The 100 folks from Diligent will get to learn the IBM wayof doing things. This brings me to our fifth and final question:
Q5. What is the correct spelling: deduplication or de-duplication?
It appears that Diligent has a corporate-wide standard to hyphenate this term (de-duplication), but the "word police" at IBM that control and standardize all "proper spellings, trademarks, and capitalization" have sent me corporate instructions a few days ago that IBM does not to hyphenate this term (deduplication). So, going forward, it will be "deduplication", or "dedupe" for short.I suspect one of the first tasks that our new IBMers from Diligent will be doing is removing all those hyphens fromthe [Diligent Technologies website]!
That's all for now, I'm off to Chicago, Illinois tomorrow!
In his post on Rough Type titled ["McKinsey surveys the new software landscape"], Nick Carr discusses the growing acceptance in the marketplace for Software-as-a-Service, or SaaS.He summarizes the results of McKinsey's recent[Enterprise Software Customer Survey 2008].IBM is already well established as part of the Web 2.0 Big "5" (the other four are Google, Yahoo, Amazon and Microsoft), so it may not be much surprise that it introduced some new offerings focused on this emerging market.
For managed hosting, [IBM Managed Storage Services] hasbeen extended to support archive data through its entire lifecycle: supporting access, migration, non-erasablenon-rewriteable (NENR) protection, and expiration/destruction. This offering supports locating the storage onthe customer premises, a hosting center, or an IBM Service Deliver Center. IBM's blended disk and tape approachprovides a better alignment between information value and storage costs.
Last December IBM acquired Arsenal Digital, which offers a remote "Enterprise Email Archive" service, supporting retention policies that can apply per user,per group, or even my message, as needed. This service provides fast user access to email archives, as well as e-discovery search. The search is not just for the email body text, but supports over 370different attachment types as well. Deduplication technology is used to reduce the actual amount of storage needed by 80percent. All of this with the security and comfort of knowing that these email archives are encrypted and protected in a disaster recovery class datacenter managed by IBM.Blocks and Files presents their thoughts on this in the article["IBM storing data and mail in the cloud"].
The Radicati Group has published some interesting statistics about email archive in[Volume 4, Issue 3]. Here's an excerpt:
"In 2007, a typical corporate email account receives about 18 MB of data per day. This number is expected to grow to over 28 MB by 2011. Today, there is no way to effectively manage these messages, but with the help of an archiving solution.
Today, the worldwide percentage of corporate mailboxes protected by archiving solutions is estimated to be around 14%, however it is growing at a fast pace, and is expected to reach over 70% by 2011.
A survey of 102 corporate organizations worldwide, showed that 68% of large businesses view compliance as their top security concern in 2007."
For those who are actually providing these services to others, over the cloud, then you might want to use the new[IBM System x iDataPlex].Compared to traditional server environments, the iDataPlex provides five times the computing power by doubling the number of servers per rack, but with 40 percent less energy consumption. Thanks to clevercooling technology, the system can run in standard office "room temperature" environments. You cancustomize with a mix of compute, network and storage nodes to meet your application requirements.In addition to Web 2.0 and SaaS workloads, the iDataPlex can be useful for financial risk analysis,high performance computing, and even batch processing.
Whether you are looking to contract out for SaaS, or to provide a service to others over the cloud, IBM can help!
Tim Ferris started the festivities with [The Grand Illusion: The Real Tim Ferriss speaks]. He claimed that for the past year, he outsourced the writing of his blog to a writer from India, and an editor from the Philippines. Given that his post was dated March 31, and he writes frequently about the benefits of outsourcing, it appeared like a legitimate post. However, Tim fessed up the following day, claiming that it was April 1 in Japan where he wrote it.
Guy Kawasaki wrote[April Fools' Stories You Shouldn't Believe]including my favorite #12 "Ruby on Rails cited Twitter as the centerpiece of its new 'Rails Can Scale' marketing program." Speaking of Twitter, Fellow IBM blogger Alan Lepofsky from our Lotus Notes team wrote[Great, now there is Twitter Spam]. It looked like a real post, but then I realized, ... everything on Twitter is spam!
Topics like energy consumption and global warming were fodder for posts and pranks.The post[Was Earth Hour a joke again?], argued thatthe preparation of "Earth Hour" last week in effect used up more energy than the hour of this annual "lights-off event" actually saved. This reminded me of John Tierney's piece in the New York Times ["How virtuous is Ed Begley, Jr.?"] where a scientist explains that it is more "green" for the environment to drive a car short distances than to walk:
If you walk 1.5 miles, Mr. Goodall calculates, and replace those calories by drinking about a cup of milk, the greenhouse emissions connected with that milk (like methane from the dairy farm and carbon dioxide from the delivery truck) are just about equal to the emissions from a typical car making the same trip. And if there were two of you making the trip, then the car would definitely be the more planet-friendly way to go.
Wayan Vota, my buddy over at OLPCnews, writes in his post[Windows XO Child Centric Development] that the "Sugar" operating environment on the innovative Linux-based XO laptops will soon be re-named the"Windows XO Operating System", with their new motto "Windows XO: A Child-Centric Operating Platform for Learning, Expression and Exploration." The mocked up photo of an XO laptop with the Windows XO logo was excellent!
The economists from Freakonomics explain in [And While You're at it, Toss the Nickel] that it costs the US Government 1.7 cents to produce each penny. The US government loses $50 million dollars each year making pennies. Each nickel costs 10 cents to produce. This one was dated March 31, so it could actually be true. Sad, but true.
My favorite, however, was EMC blogger Barry Burke's post["5773 > c"] explaining howtheir scientists were able to reduce latency on the EMC SRDF disk replication capability:
What the de-dupe team found is that there is a hidden feature within recent generations of this chip that allow a single bit, under certain circumstances, to represent TWO bits of information.
Still, almost 34% of the total bits transferred were in fact aligned double-zeros, far more than all other bit combinations - and most importantly, these were quite frequently byte-aligned, as required by this new-found capability. Makes sense, if you think about it - most of those 32- and 64-bit integers are used to store numbers that are relatively small (years, months, days, credit charges, account balances, etc.). So that's why the team decided to use this new two-fer bit to represent "00".
Mathematically, if you can transmit 34% of the data using half as many bits, you reduce the number of bits you have to transfer in total by 17%. Which, while not necessarily earth-shattering, is nothing to be ashamed of. On top of the SRDF performance enhancements delivered in 5772 (30% reduction in latency or 2x the distance), this new enhancement adds another 17% latency improvement (or ~1.4x more distance at the same latency). Combined with 5772, SRDF/S customers could see a 50% reduction in latency. And 5773 allows SRDF/A cycle times to be set below 5 seconds (with RPQ) - this new feature adds a little headroom to maximize bandwidth efficiency for the shortest possible RPO.
Again, this looked real, until I did the math. Start with the speed of light in a vacuum of space ("c" in BarryB's title) which is roughly 300,000 kilometers per second, or put into more understandable units, 300 kilometers per millisecond. However, light travels slower through all other materials, and for fiber optic glass it is only 200 kilometers per millisecond. Sending a block of data across 100km, and then getting a response back that it arrived safely, is a total round-trip distance of 200km, so roughly 1 millisecond. However, EMC SRDF often takes two or three round-trips per write, versus IBM Metro Mirror on the IBM System Storage DS8000 which has got this down to a single round-trip. The number of round-trips has a much bigger effect on latency than EMC's double-bit data compression technique. With IBM, you only experience about 1 millisecond latency per write for every 100km distance between locations, the shortest latency in the industry.
It is good that once a year, you should be skeptical of what you read in the blogosphere, and sometimes check the facts!
