IDC, an independent industry analyst firm, put out their 4Q07"Worldwide Disk Storage Systems Quarterly Tracker" report. Here is an excerpts from their [press release
"Worldwide external disk storage systems factory revenues posted 9.8 percent year-over-year growth in the fourth quarter of 2007 (4Q07) and totaling $5.3 billion (USD), according to the IDC Worldwide Disk Storage Systems Quarterly Tracker. For the quarter, the total disk storage systems market grew to $7.5 billion (USD), up 7.6 percent from the prior year's fourth quarter. Total disk storage systems capacity shipped reach 1,645 petabytes, growing 56.3 percent."
For those wondering how an industry could grow 56.3 percent in capacity, but only 7.6 percent in revenue, it isbecause the average dollar-per-GB dropped in 2007 from $6.63 down to $4.56 (USD), representing a 31 percent decline.In the past, disk prices dropped 40 to 60 percent each year, so making single digit growth was the best major vendorscould hope for. However, lately this has slowed down to 25 to 35 percent decline, but the client demand for capacity continues at the 60 percent pace, which means that vendors could achieve double digit revenue growth soon.
Once again, IBM was ranked number 1 in total disk storage. No surprise there. Here are the details:
"Total Disk Storage Systems Market
In the total worldwide disk storage systems market, IBM lead the market with 22.9 percent followed by HP with 18.1 percent revenue share. EMC maintained the third position with 16.0 percent revenue share.
For the full year, the total disk storage systems market posted 6.6 percent growth to $26.3 billion (USD). In the total worldwide disk storage systems market, IBM and HP lead the market in statistical tie with 20.1 percent and 19.4 percent revenue share, respectively. EMC maintained the third position with 15.2 revenue revenue share."
But why focus just on disk? IDC also released their"Worldwide Combined Disk and Tape Storage 3Q07 Market Share Update", and IBM was number one for that as well,taking in 21.9 percent share. Here's a quote of IBM VP Barry Rudolph in[CNN Money]:
"IBM's continued leadership in the storage hardware market reaffirms our strategy to provide the most comprehensive tiered portfolio of storage offerings, ranging from software and services to disk and tape storage solutions," said Barry Rudolph, Vice President, Storage Stack Solutions, IBM. "IBM is the clear choice for providing information infrastructure solutions that offer the most cost-efficient, streamlined approach to help our customers increase overall productivity and maximize performance."
It is looking like 2008 is going to be a good year for IBM!

It's been a while since I've talked about [Second Life
The latest post on eightbar[Spimes, Motes and Data centers]discusses IBM's use of virtual world technology to analyze data centers in three dimensions.New World Note asks[What's The Point Of 3D Data Centers?]One would think that a simple monitoring tool based on a two-dimensional floor plan would be enough to evaluate a data center.
Enter Michael Osias, IBM (a.k.a Illuminous Beltran in Second Life). Some of the leading news sites havebegun to notice some 3D data centers that he has helped pioneer. UgoTrade writes up an article aboutMichael and the media attention in [The Wizard of IBM's 3DData Centers].
Of course, in presenting these "Real Life/Second Life" (RL/SL) interactive technologies, IBM is sometimes the target of ridicule. Why? Because IBM is 10 years ahead of everyone else. So, are there aspects of a data center where 3D interfaces makes sense? I think there is.
- Topology Viewer
IBM TotalStorage Productivity Center has an awesome "topology viewer" that shows what servers are connectedto which switches, to which disk systems and tape libraries. This is all done in a 2D diagram, generated dynamicallywith data discovered through open standard interfaces, similar to what you might draw manually with toolslike Visio. Imagine, however, howmore powerful if it were a 3D viewer, with virtual equipment mapped to the physical location of each pieceof hardware on the data center floor, including the position on the rack and location on the data center floor.
- Temperature Flow
Designing computer room air conditioning (CRAC) systems is actually a three dimensional problem. Cold air isfed underneath the raised floor, comes up through strategically placed "vent" tiles, taken in the front ofeach rack. Hot air comes out the back of each rack, and hopefully finds ceiling duct intake to get cooled again.The temperature six inches off the floor is different than the temperature six feet off the floor, and 3Dmonitor tools could be helpful in identifying "hot spots" that need attention. In this case "spimes" representsensors in the 3D virtual world, able to report back information to help diagnose problems or monitor events.
- Server consolidation
After many people left the mainframe in favor of running a single application per distributed server, the pendulumhas finally swung back. Companies are discovering the many benefits of changing this behavior. "Re-centralization" is the task at hand. Thanks to virtualization of servers, networks and storage, sharing common resources canonce again claim the benefits of economies of scale. In many cases, servers work together in collective unitsfor specific applications that might benefit better if consolidated together onto the same equipment.
IBM's "New Enterprise Data Center" vision recognizes that people will need to focus on the management aspectsof their IT infrastructure, and 3D virtual world technologies might be an effective way to getthe job done.

I am always amused in the manner the IT industry tries to solve problems. Take, for example, theprocess of backups. The simplest approach is to backup everything, and keep "n" versions of that.Simple enough for a small customer who has only a handful of machines, but does not scale well. Inmy post [Times a Million
],I coined the phrase "laptop mentality", referring to people's inability to think through solutions in large scale.
Apparently, I am not alone.Steve Duplessie (ESG) wrote in his post[Random Thoughts]:
"I may even get to stop yelling at people to stop doing full backups every week on non-changing data (which is 80 %+) just because that's how they used to do it. They won't have a choice. You can't back up 5X your current data the way you do (or don't) today."
Hu Yoshida (HDS) does a great job explaining that thereare three ways to perform deduplication for backups:
- Pre-processing. Have the backup software not backup unchanged data.
- Inline processing. Have an index to filter the output of the backup as it sends data to storage.
- Post-processing. Have the receiving storage detect duplicates and handle them accordingly.
Here's an excerpt from his post[Deduplication Ratios]:
"A full backup of 1TB data base tablespace is taken on day one. The next day another full backup is taken and only 2GB of that backup has any changes.
Using traditional full backup approaches after 2 nights, the backup capacity required is 2 x 1TB = 2TB
One method of calculating de-duplication ratios could yield a low ratio:
- Total de-duplicated backup capacity used = 1TB + 2GB = 1.002TB
- If the de-duplication ratio compares the amount of total physical storage used to the total amount that would have been used by traditional backup methods, the ratio = 2TB / 1.002TB = approximately 2:1
Another method of calculating de-duplication ratios could yield a high ratio:
- Total de-duplicated backup capacity used still = 1.002TB
- If the de-duplication ratio compares the amount of data stored in the most recent (second) backup to the amount that would have been used by traditional backup methods, the ratio 1TB / 2GB = 1000GB / 2GB = 500:1"
While IBM also offers deduplication in the IBM System Storage N series disk systems, I find that for backup, itis often more effective to apply best practices via IBM Tivoli Storage Manager (TSM). Let's take a look at some:
- Exclude Operating System files
Why take full backups of your operating system every day? Yes, deduplication will find a lot to reduce fromthis, but best practices would exclude these. TSM has an include/exclude list, and the default version excludesall the operating system files that would be recovered from "bare machine recovery" or "new system install"procedures. Often, if the replacement machine has different gear inside, your OS backups aren't what you need,and a fresh OS install may determine this and install different drivers or different settings.
- Exclude Application programs
Again, yes if there are several machines running the same application, you probably have opportunity for deduplication. However, unless you match these up with the appropriate registry or settings buried down in theoperating system, recovering just application program files may render an unusable system. Applications are bestinstalled from a common source that are either "pushed" through software distribution, or "pulled" from an application installation space.
If you have TB-sized databases, and are only doing full backups daily to protect it, have I got a solution for you.IBM and others have software that are "application-aware" and "database-aware" enough to determine what haschanged since the last backup and copy only that delta. Taking advantage of the TSM Application ProgrammingInterface (API) allows for both IBM and third party tools to take these delta backups correctly.
- User Files
Which leaves us with user files, which are often unique enough on their own from the files of other users,that would not benefit from file-level deduplication. Backing up changed data only, as TSM does with its patented ["progressive incremental backup"] method, generally gets most of the benefits described by deduplication, without having to purchase storage hardware features.
Of course, if two or more users have identical files, the question might be why these are not stored on acommon file share. NAS file share repositories can greatly reduce each user keeping their own set of duplicates.It is interesting that some block-oriented deduplication,such as that found in the IBM System Storage N series, can get some benefit because some user files are oftenderivatives of other files, and there might be some 4 KB blocks of data in common.
Last November, I visited a customer in Canada. All of their problems were a direct result of taking full backupsevery weekend. It put a strain on their network; it used up too many disk and tape resources; and it took too long tocomplete. They asked about virtual tape libraries, deduplication, and anything else that could help them. The answer was simple: switch to IBM Tivoli Storage Manager and apply best practices.

Last year, in my post [Inaugural Brand Impact 2007 Awards
], I mentioned how IBM beat out other major storage vendors for the best brand "IBM System Storage". I am proud of this, and highlighted it as one of my team's key accomplishments during my brief20-month career in marketing, which I recapped in my post[Switching Over from What and Why
] when I switched over to consulting.
This year, IBM did it again. For a second consecutive year, IBM System Storage was recognized by [Liquid Agency]as the leading brand for enterprise storage. Here is an excerpt from the [IBM Press Release]:
"IBM System Storage is the most trusted storage portfolio in the world, providing our clients leading disk, tape and storage software solutions and services. This award reflects IBM's priority in delivering information infrastructure solutions to solve our client's most critical storage challenges," said Barry Rudolph, Vice President, IBM System Storage. "We are helping clients -- from large corporations to small businesses -- intelligently manage information as a strategic business asset. We are proud to be recognized as the clear market leader in delivering solutions that help our clients manage and extract value from their information."
Liquid Agency reviewed over 250 technology brands to make this assessment.
IBM also swept a variety of other awards. Here are a few excerpts from[Datamation Announces 2008 Product of the Year Winners]:
- IBM Business Process Simulator: Innov8
The Business/IT Alignment category is critical for many companies; getting these two key divisions in sync provides a huge competitive advantage. This year’s winner – by a landslide – is IBM's [Innov8].
This Big Blue product has a touch of the sci-fi to it: it’s an interactive, 3-D business simulator intended to close the divide between IT staff and business executives. In other words, it’s…a video game. I guarantee you that in all the decades that Datamation has done its Product of the Year awards, never has a video game won. The times they are a-changin’.
- IBM System p 570 enterprise server
Whether a server is the “best” server is, in truth, based on your company’s individual needs and budgets. In the server world, with its myriad options and add-ons, one size definitely does not fit all. That said, IBM p 570 Server must fit plenty of needs; the box easily won the Enterprise Server category. IBM claims this workhorse doubles the speed of its predecessor without requiring a larger energy footprint.
- IBM Lotus Symphony
When it comes to total numbers of users, there’s no question that Microsoft Office is the 800-pound gorilla of this category. The deeply entrenched Office makes the corporate world go ‘round. Given Office’s status, it’s a major eyebrow raiser that this category was won by relative newcomer IBM Lotus Symphony. Perhaps it’s because Big Blue’s product is free (that always helps), or because IBM is itself such an established vendor. Whatever the case, consider this vote as a huge upset.
(Note: IBM Lotus Symphony is available for [free download] for Windows and Linux.When my friend purchased a new laptop that came pre-installed with Windows Vista, he was surprised to see that Microsoft Office was not included. I pointed him to Lotus Symphony, and he is running great with his existing Word, Powerpoint and Excel documents! I use Lotus Symphony on both Windows and Linux, and IBM plans to make a version available for Mac OS X-- when that happens, I have my Mac Mini G4 waiting to try it out.)
- IBM Wireless Software for Business Intelligence (BI) on the go
For most of 2007, IBM Cognos 8 Go! Mobile software supported only Blackberry units. At the end of last year, Cognos upgraded its wireless business intelligence software – which delivers business reports to on-the-go staffers – to support handhelds that run Windows Mobile OS. Naturally, this expanded the company’s user base, and likely helped Cognos 8 Go! Mobile win the Wireless Software category.
(If you have a RIM Blackberry handheld device, you can try out this[actual demo].)
Wow! That's a lot of awards. Congratulations to all my IBM colleagues who made this happen!

Yesterday, I promised I would cover other products from the Feb 12 announcement. Today I will focus on the IBM SAN768B director. Some people are confused on the differences between switchesand directors. I find there are three key differences:
- Directors are designed to be 24x7 operation, highly available with no single points of failure or repair. Generally, all components in directors are redundant and hot-swappable, including Control Processors. In switches, some components are redundant and hot-swappable, such as fans and power supplies), but not the “motherboard” or controller. Often you have to take down a switch to make firmware or major hardware changes or upgrades.
- Directors are designed to take in "blades" with different features, port counts, or protocol capabilities. You can add or remove blades while the system is up and running. Switches have a fixed number of ports. (A Small Form-factor Pluggable optical transceiver [SFP] is the component that turns electric pulses into light pulses (and visa versa). You plug the SFP into the switch, and then the fiber optic cable is plugged into the SFP).
With switches, you often start with a base number of active ports, and then can enable the rest of the ports as you need them.
- Directors have hundreds of ports. Switches tend to have 64 ports or less.
Last year, Brocade acquired McDATA. Both were OEMs for IBM, and IBM distinguished that in the naming convention. The IBM SAN***B name was used to denote products manufactured for IBM by Brocade, and a SAN***M name was used to denote products manufactured by McDATA.
At that time, Brocade and McDATA equipment did not mix very well on the same fabric, so IBM retained the naming convention so that you as a customer knew what it worked with.
Brocade now has released with new levels of both operating systems--Brocade's FOS and McDATA's EOS--and their respective fabric managers--Brocade Fabric Manager (FM) and McDATA's Enterprise Fabric Connectivity Manager (EFCM)--so that they have full interoperability.
Brocade's goal is to enhance EFCM to be a common software management platform for all of their products going forward.
IBM used the maximum port count in the name to provide some clue as to the size of the switch or director. The SAN16B-2 or the SAN32B-3 are switches that have a maximum of 16 and 32 ports. The SAN256B supports a maximumeight blades of your choosing.Two different types were supported for FC ports, a 16-port blade and a 32-port blade.If all eight were 32-port blades then the maximum was 256 ports, hence the name. But then Brocade began offering 48-port blades. Should IBM change the name? No, it decided to leave itthe SAN256B even though it can now have a maximum of 384 ports.
Not to confuse anyone, the SAN768B also has a maximum of 384 ports, in the same 14U dimensions, but with a special twist. Normally to connect two directors together you use up ports from each, in what are called "inter-switch links" (ISL).These are ports you are taking away from availability from the servers and storage controllers. The SAN768Boffers a new alternative called "inter-chassis links". Each SAN768B has two processing blades, and each has two ICL ports, so with just four two-meter (2m) cables, you get the equivalent of 128 FC 8 Gbps ISL links without using 128 individual ports on each side. That is like giving you 256 ports back for use with servers and storage!
Since IBM directors require 240 volt power, IBM TotalStorage SAN Cabinet C36 include power distribution units (PDUs). PDUs are just glorified power strips, but a new intelligent PDU (iPDU) option introduces additional intelligence to monitor energy consumption for customers looking to measure, and perhaps charge back, energy consumption to the rest of the business. You can stack two SAN768B in one cabinet, one on top of the other, and connected via ICLs, it wouldlook like one huge 768-port backbone.
As a backbone for your data center, the SAN768B is positioned for two emerging technologies:
- 8 Gbps Fibre Channel (FC)
The SAN768B is powerful enough to have 32-port blades run full speed on all ports off-blade without oversubscription. Oversubscription is an emotional topic.
Normally, blades (like switches) can handle all traffic at full speed without delays provided the in-bound and out-bound ports involved are all on the same blade. In a director, however, if you need to communicate from a port on one blade to a port on a different blade, it is possible that off-blade traffic might be constrained or delayed in its transit across the backplane.
On the SAN768B, both the 16-port and 32-port blades can run at full 8 Gbps speed, and the 48-port is exposed to oversubscription only if you have more than 32-ports running at full 8 Gbps transferring data off-blade concurrently.
The new 8 Gbps SFPs support auto-negotiation at N-1 and N-2 generation link speeds. This means that they will automatically slow down when communicating with 4Gpbs and 2 Gbps devices, but they cannot communicate with 1 Gbps devices. If you are still using 1 Gbps devices in your data center, you will need to use 4 Gbps SFPs (which also support 2 Gbps and 1 Gbps link speeds) to communicate with those older devices.
- Fibre Channel over Ethernet (FCoE)
Wikipedia has a good summary of [FCoE].
Basically, this new technology enables transport of Fibre Channel packets over 10 Gbps Ethernet links. This 10 Gbps Ethernet can also be used to carry traditional iSCSI and TCP/IP traffic. FCoE introduces new extensions to provide Fibre Channel characteristics, like being lossless, and offering consistent performance. The ANSI T11 team is driving FCoE as an open standard, and at the moment it is not fully baked. I suggest you don't buy any FCoE equipment prematurely, as pre-standard devices or host bus adapters could get you burned later when the standard is finalized.
The idea is that FCoE blades can be installed in a SAN768B along with traditional FC blades, allowing routing of traffic between traditional FC and new FCoE ports. Those who have invested in FCIP for long distance replication will be able to continue using either FC or FCoE inputs.
One of the big drivers of FCoE is IBM BladeCenter. Currently, most BladeCenter blades support both Ethernet and FC connectivity and are connected to both Ethernet and FC switches on the back of each BladeCenter chassis. With FCoE, we have the potential to run both FC and IP traffic across simpler all-Ethernet blades, connecting through all-Ethernet switches on the backs of each chassis.
For more information on the IBM SAN768B, see the [IBM Press Release]. For more detailson Brocade's strategy, here is an 8-page white paper on their[Data Center Fabric] vision.

Today is Tuesday, a good day for announcements and good news!
This week I am in Guadalajara, Mexico, and the focus in Mexico is Small and Medium sized Business (SMB). SmallBusinessComputing.COM put out their [2008 Awards: The Absolute Best in Small Business], and IBM disk and server systems were recognized. Here is an excerpt:
As companies expand, so does the data, and often at an alarming rate. Adding dedicated storage to your network can ease both system performance and efficiency woes, making your work life a bit easier.
This year, 42 percent our readers cast their lot with the [IBM System Storage DS3400]. The $6,495 system supports 12 hard disk drives for capacity of up to 3.6 terabytes a good match for tasks such as managing databases, e-mail and Web serving.
Last year's winner, NetApp, takes a very respectable runner-up slot for the NetApp Store Vault S300, a $3,000 storage appliance that offers security, scalability, data protection and simplified management.
Also, IBM's SMB departmental machine, the [System i515 Express] was named runner-up for servers.

This week I'm in beautiful Guadalajara, Mexico teaching at our[System Storage Portfolio Top Gun class
].We have all of our various routes-to-market represented here, including our direct sales force, our technicalteams, our online IBM.COM website sales, as well as IBM Business Partners.Everyone is excited over last week's IBM announcement of [4Q07 and full year 2007 results
], which includesdouble-digit growth in our IBM System Storage business, led by sales of our DS8000, SAN Volume Controller and Tapesystems. Obviously, as an IBM employee and stockholder, I am biased, so instead I thought I would provide someexcerpts from other bloggers and journalists.
New York Times [I.B.M. Posts Strong Preliminary Results] said "The fourth quarter usually is the best time of the year for IBM Corp., but rarely does it look this good." When the final results were posted last Thursday, Steve Lohr wrote[IBM - A Separate Reality?]. Here'san excerpt:
But what was striking in the company’s conference call on Thursday afternoon was the unhedged optimism in its outlook for 2008, given the strong whiff of recession fear elsewhere.
The questions from Wall Street analysts in the conference call had a common theme. Why are you so comfortable about the 2008 outlook? Now, that might just be professional churlishness, since so many of them have been so wrong recently about I.B.M. Wall Street had understandably thought, for example, that I.B.M.’s sales to financial services companies — the technology giant’s largest single customer category — would suffer in the fourth quarter, given the way banks have been battered by the mortgage credit crunch.
But Mr. Loughridge said that revenue from financial services customers rose 11 percent in the fourth quarter, to $8 billion. The United States, he noted, accounts for only 25 percent of I.B.M.’s financial services business.
The other thing that seems apparent is how much I.B.M.’s long-term strategy of moving up to higher-profit businesses and increasingly relying on services and software is working. Its huge services business grew 17 percent to $14.9 billion in the quarter. After the currency benefit, the gain was 10 percent, but still impressive. Software sales rose 12 percent to $6.3 billion.
Trade Radar poses the question[IBM Beats -- but is itrepresentative of entire tech sector?]. Here's an excerpt:
Looking at IBM's business segments, it can be seen that they offer far more coverage of the technology space that those of the typical tech company:
IBM is just so big and diversified that there is little comparison between it and most other tech companies. IBM is a member of an elite group of companies like Cisco Systems (CSCO), Microsoft (MSFT), Oracle (ORCL) or Hewlett-Packard (HPQ).
IBM's wide international coverage and deep technological capabilities dwarf those of most tech companies. Not only do they have sales organizations worldwide but they have developers, consultants, R&D workers and supply chain workers in each geographic region. Their product mix runs from custom software to packaged enterprise software, hardware (mainframes and servers), semiconductors, databases, middleware technology, etc., etc. There are few tech companies that even attempt to support that many kinds and variations of products.
As color on the fourth quarter earnings announcement, there are a couple of observations that I would like to make. The first one speaks to IBM's international prowess. The company indicated that growth in the Americas was only 5%. International sales were a primary driver of IBM's good results. As an insight on the difference between IBM and most other tech companies, it is clear that nowadays, a tech company that isn't adept at selling internationally is going to be in trouble.
Sramana Mitra opines [IBM Also Looks Safe]. Here's an excerpt:
Terrific performance in a terrific year - no doubt a result of its strong global model. IBM operates in 170 countries, with about 65% of its employees outside US and about 30% in Asia Pacific. For fiscal 2007, revenues from Americas grew 4% to $41.1 billion (42% of total revenue), [EMEA] grew 14% to $34.7 billion (35%of total revenue), and Asia-Pacific grew by 11% to $19.5 billion (19.7% of total revenue). IBM sees growth prospects not just in [BRIC] but also countries like Malaysia, Poland, South Africa, Peru, and Singapore.
Meanwhile, Dan Farber and Larry Dignan from ZDnet write[IBM’s alternate universe: Big Blue sees great 2008]. Here'san excerpt:
Thus far 2008–all two weeks of it–hasn’t been a pretty for the tech industry. Worries about the economy prevail. And even companies that had relatively good things to say like Intel get clobbered. It’s ugly out there–unless you’re IBM.
I am sure there will be more write-ups and analyses on this over the next coming weeks, and others will probably waituntil more tech companies announce their results for comparison.

This week was the 2008 MacWorld conference. I thought I would reflect on some of the storage related aspects of the products mentioned by Steve Jobsin his Keynote address.Many were updated version of products introduced last year's MacWorld. (In case you forgot whatthose were, here ismy post that covered [MacWorld 2007
(Disclaimer: IBM has a strong working relationship with Apple, and manufacturers technology used in someof Apple's products. I own both an Apple iPod as well as an Apple G4 Mac Mini. IBM supports its employees usingApple laptops instead of Windows-based ones for work, and IBM has developed software that runs on Apple's OS X.Apple is kind enough to extend its "employee discount prices" to IBM employees.)
- [Apple OS X 10.5 Leopard operating system]
In the first 90 days of its release, Apple sold 5 million copies, representing 19 percent of Mac users. I am stillone of the 81 percent still using 10.4 Tiger, the previous level. My Mac Mini is based on G4 POWER processor, and upgrading is on my [Someday/Maybe] list. I am not taking sides in the [OS X vs. Windows vs. Linux religious debate]; I use all three.
The key storage-related feature of Leopard is their backup software Time Machine, and Steve Jobs announceda companion product called Time Capsule that would serve as the external backup disk wirelessly, over 802.1nWi-Fi. For many households, backup is either never done, or done rarely, so any help to simplify and relieve theburden is welcome.
Time Capsule comes in 500GB and 1TB SATA disk capacities, which Steve Jobs called "server-grade". What about a 750GB model? Looks like Apple followed EMC'sexample and went straight to 1TB instead. After EMC failed to deliver 750GB drives in 2007 that they [promised back in July], EMC blogger Chuck Hollis explains in his post[Enterprise Storage Strikes Back!]:
So there's something in the EMC goodie bag as well for you -- the availability of the new 1TB disk drives you've been hearing about. We skipped the 750GB drive and went right to the 1TB drive.
- Apple iPhone and iPod Touch
In the first 200 days, Apple has sold 4 million phones, and has garnered nearly 20 percent of the smart phone market share. New features include a GPS-like location feature that uses [triangulation] with cell phone towers and Wi-Fi hotspotsto determine where you are located.
I covered last year's introduction of the iPhone in my post on [Convergence].All of the features he presented were software updates to the existing 8GB and 16GB models. No new modelswith larger storage were introduced.
I am a T-mobile customer, so am out of luck until either (a) Apple unlocks their phones from the AT&T network, or(b) Apple signs an agreement with T-mobile in the USA. I reviewed the various hacks to unlock iPhones last year, but was not interested in losing official warranty or future software support.
The iPod Touch is an interesting alternative. It is basically an iPhone with the cell-phone features disabled, whichgives you Wi-Fi over the Safari browser, music, videos, and so on. Steve Jobs mentioned enhanced software updates for this as well. The iPod Touch comes in the same 8GB and 16GB sizes as the iPhone.
- AppleTV and iTunes
Steve Jobs indicated that they have sold over 4 billion songs over iTunes, 125 million TV shows, and 7 million movies.He announced that now iTunes would allow for movie rentals, with the option to see them within 30 days, but once you started watching a movie, you have 24 hours to finish. I found it interesting that he said rentals were to reduce space on your hard drive, versus outright purchase of movie content.
In a rare concession, Steve admitted that the original AppleTV misunderstood the marketplace. The original AppleTV allowed you to view pictures and listen to music through your television, but people wanted to view movies. Thesoftware upgrade would allow this, using the iTunes rental model above, as well as watch video podcasts and over 50 million videos posted on YouTube.
Some television-related stats from [z/Journal] were quite timely. The older non-digital TVs could be usedwith the AppleTV and gaming systems like Nintendo Wii.
- 33 percent of U.S. households do not know what to do with (their older) TVs after digital switch (Feb 2009)
- 69 percent of Americans think PCs are more entertaining than TV
Rather than try to fight peer-to-peer website piracy, Apple cleverly decided to compete head-to-head against it. This iswell summarized in Matt Mason's 6-minute video [The Pirate's Dilemma]. Eleven major movie studios are on board with Apple's movie rental plans, making thousands of movietitles available for this, with hundreds in High Definition (HD).
I personally have a Tivo, connected wirelessly to a regular non-HD television, as well as my PC, Mac and internet hub, and this allows me to view my photos, listen to my iTunes collection of music and internet radio stations from [Live365], as well as rent movies and TV shows from Amazon Unbox, with prices ranging from free to four dollars.

The theme of this week was "Something is in the Air", an obvious reference to this product, billed as the world's thinnest laptop.John Windsor on his YouBlog writes[Making it Memorable] aboutthe use of a standard office envelope to demonstrate how thin this new MacBook Air laptop is. It is 0.16 inchesat one end, and 0.76 inches as the other end. Unlike other "ultra-thin" laptops, this has a full-size back-lit keyboardand full-size 13.3 inch widescreen. The touchpad supports multi-touch gestures similar to the iPhone and iPod Touch.Intel managed to shrink down their Core 2 Duo processor chip by 60 percent to fit inside this machine. Thebattery is reported to last five hours.
This laptop was designed for wireless access, with 802.1n and BlueTooth enabled. No RJ-45 connection for traditionalLAN ethernet connection, but I guess you can use a USB-to-RJ45 converter.
Storage-wise, you can choose between the 1.8-inch 80GB HDD or a pricey-but-faster 64GB Flash Solid-State Disk (SSD).In a move similar to [getting rid of the 3.5-inch floppy disk in 1998's iMac G3], the MacBook Air got rid of the CD/DVDdrive. While they offer a USB-attachable SuperDrive as an optional peripheral, Steve Jobs gave alternative methods:
|Watching movies on DVD||Rent or Buy from iTunes instead|
|Burning music CDs for your car stereo||Attach your iPod to your car stereo|
|Taking backups to CD or DVD||Use Time Machine and Time Capsule instead|
|Installing Software from CD||Wirelessly connect to a "Remote Optical Disc" on a Mac or PC, running special Apple-provided software that allows you to make this connection|
Here's a list to the 90-minute[keynote address video]. If you arenot a fan of recycling, saving the environment, free speech or democracy, you can safely skip the last 15 minutes when musical artist Randy Newman performs.For alternative viewpoints on the keynote, see posts from [John Gruber] and [Tara MacKay].

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.

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.
