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:
This week I will cover applications that address these, and how they relate to storage.Read More]
Over 4,000 issues of your favorite magazine now sit, ready for you to search and savor, on an 80GB incredibly lightweight and travel-friendly drive. This high-performance, brushed-aluminum Hard Drive measures only 3x5-inch and can easily fit inside a purse or briefcase so show it off to your tech-savvy friends and co-workers. Plus, there is plenty of extra room on the drive for future updates. Simply install The Complete New Yorker Program (installation CD provided), then connect the drive to a USB port on your Computer and have instant access to every article, poem, short story, and cartoon including every advertisement that has appeared in the magazine since 1925.
The 750MB of disk space required on your system probably contains the indexing/metadata search system to find articles by subject, title or author. Linux is not listed, and if 750MB of disk space are required to run the program, then perhaps this system won't work with Linux at all.
The system claims that there is extra room on the disk to ingest future issues of the magazine. I wonder why they didn't put the indexing/metadata search software on the drive itself, so that it would be self-contained, rather than having a separate installation CD.
I think this is a sign of our times. The New Yorker magazine has taken the archives that they keep anyways, and made them available in bulk, in a handy disk drive delivery system. I know several people who keep boxes and boxes of back issues of all kinds of magazines, and this certainly is an improvement.
This week I was in Palm Springs in meetings with clients, prospects, business partners and IBM sales reps.
Tuesday consisted of "outdoor meetings", but the high winds caused some people to arrive late, and others to land in the various sand traps and water hazards. A "welcome reception" event allowed everyone to socialize and get to know the IBM experts and executives. Two of my colleagues, Mike Stanek and Dave Wyatt, were with me also in Australia last week, and so the three of us were discussing recovery from jet lag.
Wednesday was organized as a main tent event, where everyone met into one large room to hear our strategy,latest set of offerings, and customer testimonials. This was done indoors, of course, which was a good thing as the winds were now gusting up to 50 miles per hour, knocking over windmills and making the local news.
Here's a quick sample from the testimonials:
The event got great reviews, and I look forward to the next one. Until then, enjoy the weekend!
Today, I went looking for reading-glasses. Unfamiliar with my surroundings, I asked several people where I might be able to find and purchase these, and was sent in various directions. My first stop was a bookstore. It would make sense that since many people need reading glasses to read the books, that they would sell them there, but no. The staff didn't know where I could go, but pointed me in the direction of a mall. At the mall, I found a pharmacy. Many pharmacies sell reading glasses, so I stopped in, but no, not this one. The pharmacists suggested the super-store nearby. I walked in to the super-store, and asked the first employee where they keep their reading glasses, and they said the other corner. The other corner was the electronics department. It made sense that they sold CDs and DVDs in the same section as the equipment that plays them, but reading glasses? Skeptical, I went to the pharmacy department, and the young and beautiful lady (everyone is young, thin and beautiful here) had me follow her, and she led me back to the electronics department, whereupon she pointed to a rack of sunglasses. I indicated that I need reading glasses, not sunglasses. She pulled one out, and it was indeed reading glasses, 1.25, just what I was looking for. Others were tinted, so you can read the newspaper out in the sunlight. The pair I chose cost only $97 in the local currency.
After reading the last sentence, you might be thinking I am describing my "avatar" in Second Life, but no, I am talking about my search for reading glasses on the streets of Mexico. I am here this week in meetings with IBM Business Partners and sales reps to discuss IBM's latest System Storage products and offerings.
We used to tell people they should "clothe" servers with storage. IBM offers both, so yes it makes sense to offer both as part of a complete solution. However, when you look through a dictionary definition "to clothe" you learn it is to dress, wrap or cover with clothing, an implication that it is external, and perhaps temporary, easily changed, like switching from sunglasses to reading glasses. In Second Life, objects can be "worn", simply by attaching or detaching them to your "avatar". Sometimes clothing serves a purpose, like reading glasses, provides protection, like raincoats, and other times, more decorative, like"icing on the cake" or "gold plating".
This concept was fine 50 years ago, when we were in a server-centric world, and dumb storage devices were attached to very intelligent servers. Back then, we used the derogatory term "subsystems" to emphasize that storage was just part of the server, not a system of its own.
Today, we live in an information-centric world. The information outlives the media, and the media outlives the servers that access it. It is not unreasonable to attach dozens or hundreds of servers to a single storage system, or collection of storage systems. Over 20 percent of IBM System Storage DS8000 series, for example, are attached to Windows rack-optimized or blade servers. Imagine a refrigerator surrounded by dozens or hundreds of pizza boxes. Storage is no longer a subsystem, but a system on its own right, dressed, wrapped or covered by servers that deliver the right information, to the right people, at the right time.
So perhaps we should reverse it, telling people they should "clothe" their storage with servers!
On the news today, they mentioned it was "Happy Pi Day". Today is the 14th day of the 3rd month, and "pi" is about 3.14159, the ratio of the circumference of a circle to its diameter. So, in Tucson it is celebrated on 3/14, at 1:59pm MST.
The ratio has a lot to do with storage.
The value of "pi" has been calculated to over a billion significant digits. Here is a cuteapplet to use if you ever need the value to any level of accuracy.
Continuing my coverage of SNW Spring 2007, Ron and Vincent kicked off Wednesday main tent sessions with more survey questions:
Q1. How secure is your storage network?
Q2. What was the cause of most downtime in last 12 months?
Thornton May, futurist and columnist for ComputerWorld, presented "Storage 3.0: What Comes After, What Comes Next."I have seen several "futurists" present at conferences like this. They all feel the need to explain what their job is, and what it takes to be one. This time, Thornton indicated he was "ridiculously well-travelled, amazingly well-connected, pathologically observant, and brutally honest." His insights:
Gabriel Broner, General Manager of the newly created "Storage Solutions" division of Microsoft, presented "The Drive to Unified Storage". The people sitting around me asked "What does Microsoft have to do with storage?" He defined "Unified Storage" the way we use it for IBM Sytstem Storage N series "a storage unit that provides both file and block level protocol support." Microsoft is using "e-mail" as the model for data access, identifying the need to have "off-line" copies on your PC or laptop that are synced up with "on-line" sources. Features that were typically only available for high-end applications are now being made available to the masses, like "Volume Snapshot" capability in Windows Vista. On the home front, Microsoft recognizes that typically one person acts as the "IT manager" for the family.
Their survey of storage spend of Fortune 1000 companies. It was not clear if this was for Windows environments, or how the data was collected. These numbers don't match what we hear from our UNIX or mainframe customers.
Microsoft is implementing application changes, such as Office 2007, to simplify storage issues. Storage virtualization is the key for the future, he says, stating that Microsoft's "iSCSI target" software support makes files look like block-oriented volumes. Virtualization is now mainstream, and deploying software on standard hardware is the new storage business model. The end goal is to simplify provisioning, device and resource management, without reducing functionality, narrowing the gap between general IT tasks and specific storage tasks.
Craig Lau, NBC Olympic coverage, presented their success story. Look at the number of "hours" of TV Olympic coverage over the years:
NBC now is able to deliver 70 hours of TV programs per day, shown across their seven channels (NBC, CNBC, MSNBC, Brave, USA Network, Telemundo, and HD-tv). The Olympics in Torino, Italy generated 25,000 tapes in 17 days. Their 100,000 tape Olympic repository is starting to deteriorate, and they need to consider conversion to digital format. Their challenge was that footage was difficult to find and producers needed immediate access to time sensitive/critical content.
Their solution was Digital Asset Management, automating indexing and logging, using an IP-based workflows that reduces the number of people at the Olympics location, and allowing content to be sent back to USA for remote editing.The facilities at Torino involved:
NBC is frustrated by the lack of compatability and interoperability in the video format industry. They have been testing MPEG-1 (1.5 Mbps) formats, and plan to deploy a new system using 1080i for the upcoming 2008 Olympics in Beijing. With the new system, they can index footage by athlete, by event, and by human emotional reaction. They can review and edit footage within 30-45 seconds of live coverage, allowing rough edits to be documented as "Edit Decision Lists" that can be e-mailed or put on USB key for others to review.
Although I missed Anil Gupta's "Blogger Event" on Monday, several bloggers did stop by to visit me at the IBMbooth.

The blogosphere has quieted down a bit over the two papers on MTBF estimates for Disk Drive Modules (DDM).One article on SearchStorage.com by Arun Taneja asksIs RAID passé? Disk capacity is growing at a faster rate than DDM reliability. During the hours to rebuild a DDM, companies are at risk of additional failures that could require recovery from a copy, or result in data loss, depending on how well your Business Continuity (BC) plan is written and followed.
I'll discuss two comments in particular.
Both are fair comments. Disk arrays do run microcode to assist or perform the RAID function, detect failures and start the rebuild process, and so clever designs to support spare disks, process the rebuild quickly, and so on, can differentiate one vendor's offering from another.
On the issue of what does IBM provide to help its clients make the right decisions for their environments, Jon William Toigo at DrunkenData points his readers to IBM's Business Continuity Self-Assessment tool. In normal data center conditions, DDMs will fail, and a Business Continuity plan shouldbe written and developed to handle this fact. Using 2-site and 3-site mirroring, complemented with versions of tape backups, can help address some of these concerns and mitigate some of the risks involved with using disk systems.
For those who want a more technical answer, IBM has just published a series of IBM Redbooks.
The smart people at the University of Pittsburgh manage five campuses and over 33,000 students, andneeded to create an enterprise storage solution that would give it three key benefits. Of course, they turnedto IBM, the number one overall storage hardware vendor, to deliver.
Here is what Jinx Walton, Director of Computing Services and Systems Development at the University of Pittsburgh, had to say about it...
"The University of Pittsburgh supports large enterprise systems, and the number and complexity of new systems continue to grow. To effectively manage these systems it was necessary to identify an enterprise storage solution that would leverage our existing investments in storage, make allocation of storage flexible and responsive to project needs, provide centralized management, and offer the reliability and stability we require. The integrated IBM storage solution met these requirements"

I would like to welcome IBMer Barry Whyte to the blogosphere!
From his bio:
Barry Whyte is a 'Master Inventor' working in the Systems & Technology Group based in IBM Hursley, UK. Barry primarly works on the IBM SAN Volume Controller virtualization appliance. Barry graduated from The University of Glasgow in 1996 with a B.Sc (Hons) in Computing Science. In his 10 years at IBM he has worked on the successful Serial Storage Architecture (SSA) range of products and the follow-on Fibre Channel products used in the IBM DS8000 series. Barry joined the SVC development team soon after its inception and has held many positions before taking on his current role as SVC performance architect. Outside of work, Barry enjoys playing golf and all things to do with Rotary Engines.
To avoid confusion in future posts, I will refer to Barry Whyte as BarryW, and fellow EMC blogger Barry Burke (aka the Storage Anarchist) as BarryB.
I'm in Chicago this week, but it is actually HOTTER here than in my home town of Tucson, Arizona.
I am back from China, and now glad to be back in the old USA. Last week, someone asked me what would it take to add a specific feature to the IBM System Storage DS8300. The what-would-it-take question is well-known among development circles informally as a "sizing" effort, or more formally as "Development Expense" estimate.
For software engineering projects, the process was simply that an architect would estimate the number of "Lines of Code" (LOC) typically represented in thousands of lines of code (KLOC). This single number would convert to another single number, "person-months", which would then translate to another single number "dollars". Once you had KLOC, the rest followed directly from a formula, average or rule-of-thumb.
More amazing is that this single number could then determine a variety of other numbers, the number of total months for the schedule, the number of developers, testers, publication writers and quality assurance team members needed, and so on. Again, these were developed using a formula, developed and based on past experience of similar projects.
Earlier in my career, I was the lead architect for DFSMS for the z/OS operating system, and later for IBM TotalStorage Productivity Center, performing these sizing efforts. A famous IBM architect, Frederick P. Brooks, wrote a now-classic book that was requiredreading when I started at IBM, which just was re-released as Mythical Man-Month: Essays in Software Engineering, 20th Anniversary Edition. In addition to sound advice, he alsooffered a formula or two that helps with these estimating tasks.
Hardware design introduces a different set of challenges. When I was getting my Masters Degree in Electrical Engineering, it took myself and four other grad students a full semester just to design a six-layer, 900 transistor silicon chip, which could only perform a single function, multiply two numbers together.At IBM, another book that I was given to read was Soul of a New Machine, documenting six hardware engineers, and six software engineers, working long hours on a tight schedule to produce a new computer for Data General.
So why do I bring this up now? IBM architects William Goddard and John Lynott are being inducted posthumously this year into the prestigious National Inventors Hall of Fame for their disk system innovation.
Under the leadership of Reynold Johnson, the team developed an air-bearing head to “float” above the disk without crashing into the disk. Imagine a fighter airplane flying full speed across the country-side at 50 feet off the ground. If you every heard the term "my disk crashed", it was originally referring to the read/write head touching the disk surface, causing terrible damage.
A uniformly flat disk surface was created by spinning the coating onto the rapidly rotating disk, leaving many wearing lab coats covered with disk liquid at waist level. Developing disk-to-disk and track-to-track access mechanisms proved more challenging, and nearly halted the project. The team, however, was adamant that this problem could be solved, and customers were increasingly asking for random access technology. The result was the "350 Disk Storage Unit" designed for the "305 RAMAC computer", which I have talked about a lot last year as part of our "50 years of disk systems innovation" celebration.
Neither Goddard nor Lynott had computing experience prior to joining IBM. Goddard was a former science teacher who briefly worked in aerospace. Lynott had been a mechanic in the Navy and later a mechanical engineer. They didn't have a nice formula based on past experience, they didn't have the benefit of Fred Brooks' advice, or the rules-of-thumb or averages now used to estimate the size of projects. They had to break new ground.
Now that's innovation!

SNW wrapped up Thursday. As is often the case, a lot of people have left already.
I saw two presentations worth discussing here in this blog.
