Many people have asked me if there was any logic with the IBM naming convention of IBM Systems branded servers. Here's your quick and easy cheat sheet:
- System x -- "x" for cross-platform architecture. Technologies from our mainframe and UNIX servers were brought into chips that sit next to the Intel or AMD processors to provide a more reliable x86 server experience. For example, some models have a POWER processor-based Remote Supervisor Adapter (RSA).
- System p -- "p" for POWER architecture.
- System z -- "z" for Zero-downtime, zero-exposures. Our lawyers prefer "near-zero", but this is about as close as you get to ["six-nines" availability] in our industry, with the highest level of security and encryption, no other vendor comes close, so you get the idea.
But what about the "i" for System i? Officially, it stands for "Integrated" in that it could integrate different applications running on different operating systems onto a [COMMON
] platform. Options were available to insert Intel-based processor cards that ran Windows, or attach special cables that allowed separate System x servers running Windows to attach to a System i. Both allowed Windows applications to share the internal LAN and SAN inside the System i machine. Later, IBM allowed [AIX on System i
] and [Linux on Power
] operating systems to run as well.
From a storage perspective, we often joked that the "i" stood for "island", as most System i machines used internal disk, or attached externally to only a fewselected models of disk from IBM and EMC that had special support for i5/OS using a special, non-standard 520-byte disk block size. This meant only our popular IBM System Storage DS6000 and DS8000 series disk systems were available. This block size requirement only applies to disk. For tape, i5/OS supports both IBM TS1120 and LTO tape systems. For the most part,System i machines stood separate from the mainframe, and the rest of the Linux, UNIX and Windows distributed serverson the data center floor.
Often, when I am talking to customers, they ask when will product xyz be supported on System z or System i?I explained that IBM's strategy is not to make all storage devices connect via ESCON/FICON or support non-standard block sizes, but rather to get the servers to use standard 512-byte block size, Fibre Channel and other standard protocols.(The old adage applies: If you can't get Mohamed to move to the mountain, get the mountain to move to Mohamed).
On the System z mainframe, we are 60 percent there, allowing three of the five operating systems (z/VM, z/VSE and Linux) to access FCP-based disk and tape devices. (Four out of six if you include [OpenSolaris for the mainframe])But what about System i? As the characters on the popular television show [LOST] would say: It's time to get off the island!
Last week, IBM announced the new [i5/OS V6R1 operating system] with features that will greatly improve the use of external storage on this platform. Check this out:
- POWER6-based System i 570 model server
Our latest, most powerful POWER processor brought to the System i platform. The 570 model will be the first in the System i family of servers to make use of new processing technology, using up to 16 (sixteen!) POWER6 processors (running at 4.7GHZ) in each machine.The advantage of the new processors is the increased commercial processing workload (CPW) rating, 31 percent greater than the POWER5+ version and 72 percent greater than the POWER5 version. CPW is the "MIPS" or "TeraFlops" rating for comparing System i servers.Here is the[Announcement Letter].
- Fibre Channel Adapter for System i hardware
That's right, these are [Smart IOAs], so an I/O Processor (IOP) is no longer required! You can even boot the Initial Program Load (IPL) direclty from SAN-attached tape.This brings System i to the 21st century for Business Continuity options.
- Virtual I/O Server (VIOS)
[VirtualI/O Server] has been around for System p machines, but now available on System i as well. This allows multiplelogical partitions (LPARs) to access resources like Ethernet cards and FCP host bus adapters. In the case of storage, the VIOS handles the 520-byte to 512-byte conversion, so that i5/OS systems can now read and write to standard FCP devices like the IBM System Storage DS4800 and DS4700 disk systems.
- IBM System Storage DS4000 series
Initially, we have certified DS4700 and DS4800 disk systems to work with i5/OS, but more devices are in plan.This means that you can now share your DS4700 between i5/OS and your other Linux, UNIX and Windowsservers, take advantage of a mix of FC and SATA disk capacities, RAID6 protection, and so on.
- IBM PowerVM
To call [IBM PowerVM] the "VMware for the POWER architecture" would not do it quite justice. In combination with VIOS, IBM PowerVM is able to run a variety of AIX, Linux and i5/OS guest images.The "Live Partition Mobility" feature allows you to easily move guest images from one system to another, while they are running, just like VMotion for x86 machines.
And while we are on the topic of x86, PowerVM is also able to represent a Linux-x86 emulation base to run x86-compiled applications. While many Linux applications could be re-complied from source code for the POWER architecture "as is", others required perhaps 1-2 percent modification to port them over, and that was too much for some software development houses. Now, we can run most x86-compiled Linux application binaries in their original form on POWER architecture servers.
- BladeCenter JS22 Express
The POWER6-based [JS22 Express blade] can run i5/OS, taking advantage of PowerVM and VIOS to access all of the BladeCenterresources. The BladeCenter lets you mix and match POWER and x86-based blades in the same chassis, providing theultimate in flexibility.
Now that's exciting!

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.

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.

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.

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.
