This week I am off to Budapest, Hungary, for business meetings. It is the closest major city to IBM'smanufacturing plant in a small town called Vac (rhymes with "knots") where the IBM System Storage DS8000 seriesand SAN Volume Controller are assembled.
Last week, I opined that Monday's IDC announcement "IBM #1 in combined disk and tape storage hardwaresales for 2006" was in part because of a resurgence of interest in tape, with four specific examples. There was a lot of reaction and reflection fromboth sides.

One of the differences between IBM and the other storage vendors is that IBM is also in the business of middleware, application-aware backup software, and advanced copy services. This allows IBM to put togethersolutions that work to address specific challenges for our clients.
IBM has written a whitepaper on a cleverVSS Snapshot Backup for Exchange using IBM Tivoli Storage Manager and the point-in-time copy capabilities of IBM System Storage disk systems.
A problem in the past was that each vendor's point-in-time copy method had its own unique proprietary interface.Microsoft Developed Volume Shadow Copy Services (VSS) as a common interface front-end to resolve this concern.IBM Tivoli Storage Manager for Mail can invoke standard VSS interfaces, and this in turn can invoke FlashCopyon the IBM System Storage SAN Volume Controller, DS8000 series, or DS6000 series disk system.
You might be thinking: Wouldn't it have been less effort to just have TSM for Mail invoke IBM proprietary interfaces,rather than having to put full VSS support into TSM for mail, and then full VSS support into IBM's various disksystems? Perhaps, but IBM doesn't decide to do things because it is the cheapest way, we focus on what is theright way, and in this case, customers now have more choices, then can use TSM for Mail with IBM or non-IBM disksystems that support the VSS interface, and IBM disk systems can be employed into other uses for VSS snapshot.
Of course, we would like our clients to consider both TSM and IBM System Storage disk systems for a combined solution,not because they are required to make the solution work, but because both are best-of-breed, and whitepapers likethis show how they can provide synergy working together.
A recent blog by Chris Mellor makes the outlandish conspiracy theory that IBM and HDS copied virtualisation technology from small start-up company DataCore.
(Chris doesn't actually name who is his source making such a claim, whether thatsomeone was employed by any of the parties involved at the time the events occurred,or is currently employed by a competitor like EMC bitterly jealous of the success IBM and HDScurrently enjoy with their offerings.)
As I already posted before about IBM'slong history of storage virtualization, SAN Volume Controller was really part of a sequence of major product in this area, after the successful 3850 MSS and 3494 VTS block virtualization products.
In the late 1990's, our research teams in Almaden, California and Hursley, UK were exploring storagetechnologies that could take advantage of commodity hardware parts and the industry-leadingLinux operating system.
As is often the case, while IBM was working on "the perfect product", small start-ups announce "not-yet-perfect" products into the marketplace. Tactical moves like partneringwith DataCore was a smart move, for the following reasons:
The partnership proved worthwhile, not just to prove to IBM that this was a worthwhile market to enter, but also how "NOT" to package a solution. Specifically, DataCore SANsymphony was software that you had to install on your own Windows-based server. The client was left with the task of orderinga suitable Intel-based server, with the right amount of CPU cycles, RAM and host bus adapter ports,and configure the Windows operating system and DataCore software.
It didn't go well. Basically, customers were expected to be their own "hardware engineers", having to knowway too much about storage hardware and software to design a combination that worked for theirworkloads. Most clients were disappointed with the amount of effort involved, and the resulting poor performance.
To fix this, IBM delivered the SAN Volume Controller, with an optimized Linux operating system and internally-writtensoftware that runs on IBM System x(tm) server hardware optimized for performance.
I can't speak for HDS, but I suspect they came to similar conclusions that resulted in a similar decisionto build their product in-house. I welcome Hu Yoshida to correct me if I am wrong on this.
I hope everyone enjoyed the French Open in Second Life! Here are some upcoming events:
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!
IDC announced that IBM was number #1 in storage hardware (disk and tape combined)for 2006. Here are some excerpts from the IBM press release:
The newly released May 2007 report  by leading industry analyst firm IDC, "Worldwide Combined Disk and Tape Storage 2006 Market Share Update," shows IBM in the #1 overall position for all disk and tape storage hardware for the full year 2006.
Five years ago, IBM was only #3 in this area, butis this new standing from IBM doing things better, or HP and EMC doing things poorly? Probably a little of both, but since it's not polite to point out the flaws of others in a blog, I will focus on what IBM is doing right, and I think our leadership in tape accounts for a good measure of this.
The resurgence of tape comes from a variety of factors:
For more details, see IBM's press release.
In a recent post, ESG Analyst Tony Asaro asks What happened to CAS?
Many often associate CAS with EMC's Centera offering, but with IBM's comprehensive set of compliance storageofferings, EMC doesn't talk about CAS or Centera much anymore.I covered the confusion around CAS in a previous post. When clients ask for "CAS" what they really are looking for is storage designed forfixed content, unstructured data that doesn't change once written. A lot of data falls under this category, such as scanned documents, audio and video recordings, medical images, and so on. Some laws and regulations further require enforcement that the data is not deleted or tampered with, until some time after an event or expiration date is met.
In the past, clients used write-once read-many (WORM) optical media, but today we have disk and tape offerings instead. Since the term "WORM" is inappropriate fordisk-based solutions, IBM has standardized to the use of the term "non-erasable, non-rewriteable" (NENR) to discusstoday's solutions and offerings.
Let's recap what IBM has to offer:
As you see, IBM doesn't limit itself to disk-only offerings. Our leadership in tape allows us to innovate tape and disk-and-tape offerings that can provide more cost-effective solutions to store fixed content, retention managed data.The next time you have a conversation with a storage vendor, don't ask for CAS, ask instead for archive and compliance storage. Broaden your mind, and broaden the set of options and choices that might provide a better fit for your requirements.

Well it's already Tuesday here in Australia. Many people here have asked me what my secrets are for dealing withJet Lag, as many Aussies (and Kiwis) travel across time zones for business. While Sydney is 17 hours "ahead" of Arizona right now, my body feels like it is 7 hours of time zones "behind". If you do nothing, your body will naturally adjust, about one time zone per day, which is completely unacceptable for most week-long business trips.Since I have been traveling for IBM since 1989, I have read a lot on this, and tried a lot of things, and here's what works for me.
Disclaimer: I am not a doctor, consult a doctor if you have any questions
About 3-5 days before returning, go back to the "Before the Trip" process and start alternating meals again. Follow the process and act as if returning home is a new trip to deal with jet lag in the reverse direction.
Well this is what works for me, I don't take "melatonin" or other drugs that have been found useful for jet lag in hamsters. I welcome comments on what works for you.
What a great way to wrap up another excellent week!
While I was away on vacation last week, IBM Storage and Software Offeringswon Brand Impact 2007 Awardsfrom leading brand marketing organization Liquid Agencyat the Brand Summit Awards Dinner.Other awards went to Cisco, Google and Sony, which I also highly admire.
Have a safe weekend!
Yesterday, IBM announced a variety of new storage offerings. Our theme this time around was "Policies and Performance". Here's a quick recap.
Our clients tell us they need performance to meet their dynamic business demands, and policies to help them manage the ever growing size of their storage infrastructure. We listened!

I'm back. Thanks for all the comments.
For those who participated in Clark Hodge's "Where's Tony" contest,I was in Croatia, Bosnia and Herzogovina. There were optional side-tours to Montenegro and Slovenia, but I decided not to incur the added time and expense with those.
For those wondering where to go this Summer for vacation, I recommend Croatia. It is a beautiful country, with clean cities, good road conditions, and a calm Adriatic sea as we went from island to island.
And if you get to Mostar, don't let them talk you into jumping off the "old bridge". The water is terribly cold down there![Read More]
Well, I'm going to take a two week break from blogging. Not because my clarification of storage terminology got me Marc Farley's finger wagging of shame.
No, I'm going on vacation.I'll be going to a third-world country, possibly outside the reaches of cell phones, e-mail and the internet, so I won't be blogging until I get back later this month. Since Clark Hodge has discovered a pattern that I am suspiciously close to massive power failures, I think it best not to tell people exactly where I am going.
So, until I get back, I leave you with a nice piece from Kirby at Storage Sanity who has discovered that IBMers are very nice.
I'll spend my time doing non-storage related activities, like practicing to catch sunglasses with my face.I'll be back in a few weeks.
The results are finally in. IBMer Wolfgang Singer was awarded "Top Speaker" award for his NAS and iSCSI tutorial at last year's Orlando 2006 conference. Here he is receiving the awardfrom SNIA Executive Director Leo Leger.
Of course, NAS and iSCSI technologies have been around for a while, but they are still new formany customers, which is why tutorials like this are so important.
Not everyone is clear on these technologies. For example, Dave Hitz asksis iSCSI SAN or is iSCSI NAS? I Don’t Know.
To avoid this confusion, IBM adopted clarifying technology.
"Information is moving—you know, nightly news is one way, of course, but it's also moving through the blogosphere and through the Internets."As multinational companies transition to becomeglobally integrated enterprises, information is going to move across nationalboundaries. Laws that pertain to how data is stored and access need to be addressed.
Jon W Toigo over at DrunkenData.com discusses an Interesting proposal on Google Censorship. The New York Sun reports that NYC comptroller, Williams Thompson Jr. istargeting both Google and Yahoo over theirpolicies of abiding the local laws in each country they do business in.The proposal includes asking Google to fight local laws, publicize when Google complies withlocal laws, and publicize when local governments ask Google to comply with their laws. While Toigo focuses on Google, this issue applies to Yahoo, Microsoft, and many other companies that do business in multiple countries.
I admire when government officials use diplomacy to influence the policy of other governments, andwhen individuals act to influence the policies of those who govern them, but Thompson isdoing neither.In this matter, Thompson is trying to influence thepolicies of another government outside his jurisdiction, as a manager of investments in companies that do business there.Investors have two choices when trying to influence how companies do business.
It appears Thompson is exercising the latter, proposing that this issue be brought to shareholder vote via proxy.There can only be two results from such a vote, either:
Did we forget that we have censorship in the USA as well? Would Thompson's proposalsapply to the rules and regs that our own government requires?
IBM does business in most, not all, countries on this planet. In the countries we don't do business in, we havegood reason not to. For the countries we do, we comply with all the laws that apply in each case.When I travel to these countries, including some of the countries specifically targeted by this proposal, I must abide by their laws. No exceptions.
The world is shrinking, and technologies now allow companies to become globally integrated. Before writing"The World Is Flat", Thomas Friedman wrote a book titled The Lexus and TheOlive Tree, which covers all the various issues related to conflicts between global companies and the countriesand cultures they do business in.
This reminds me of the wisdom of the Prime Directiveintroduced in the late 1960s on the popular TV show "Star Trek". The concept was simple, honor the sovereigntyof other cultures, on other worlds, and play by their rules when you are on their planet.I say "wisdom" in that it took me years to truly appreciate this idea.Initially, I considered this just a plot device to introduce conflict each time the captain and crew of thestarship "Enterprise" visits a new location, and discovers a culture different than their own. But over the years, as I have traveled to many countries, I began to see and understandthe wisdom of the "Prime Directive", and it applies as much now, in real life, as it did back then in the futuristic 1960s TV show.
Who are we to say that our way of doing things is the one and only way to do them?
Continuing this week's theme on virtual worlds, I saw thatGartner predicts 80% of the online community will be using virtual worlds like Second Life by 2011.ComputerWorld ranks the top 8 corporations present in Second Life, IBM ranks #1.
Well, I'm off on another business trip.
Today was the "First Ever Live Virtual Virtualization Tech Fair" sponsored by IBM and VMware. This was a 1-day event hosted by Unisfair.
The day included presentations done at a conference call, along with exhibition booths.
We had an exhibition booth exclusively for "storage virtualization" featuring our IBM System Storage SAN Volume Controller (disk virtualization) and IBM System Storage TS7520 Virtualization Engine (a virtual tape library, or VTL).
People who were logged in were represented in silhouette form. When someone walked into the booth, our army of "booth reps" were able to chat with them and answer their questions. They could also peruse the various online materials we made available about each product.
Here are some of my observations:

This week (actually April 29 to May 2) is IBM'sPartnerWorld 2007 conference.Over the past 10 years, IBM's shift to rely more heavily on business partners has proven to be a smart decision. IBM Business Partners can often focus on a specific region or industry much better, with laser-like focus.
In case you missed it, IBM launches System Storage products in Second Life was a great success, and the Business Partner community is a-buzz about this new technology for their own usage. Here is a quick 2-minute highlight clip of the event:
One of the reporters we invited to the event, Heather Clancy from CRN, wrote an article about it: Second Life: Ready or Not.
IBM Business Partners are glad to see IBM lead the storage industry in new and innovative ways!
I'm wrapping up my week in Latin America.
Yesterday morning, the entire country of Colombia suffered their worst black-out (power outage) in 22 years. 98% of the country was out for 4 1/2 hours.This is just 5 months after an outage that hit 25% of the country, December 7, 2006.Ironically, this one happened the week I am here explaining the need for Business Continuity plans to IBM Business Partners from Argentina, Peru, Velenzuela, Ecuador and Colombia. As is oftenthe case, people often need a real example to recognize the need for planning is important.
It reminded me of the Northeast Black-out of 2003 that impacted USA and Canada. I was speaking to a crowd of 800 people at the SHARE conference in Washington D.C. when it happened, and hundreds of pagers and cell-phones went off all at the same time. Although we were outside the effected area and had plenty of lighting, we ended up canceling therest of my talk, and many people left immediately to help execute their business continuity plans.Of course, terrorism was immediately assumed, but a final report showed that it was initiated in Ohiodue to overgrown trees, and then propagated due to a software bug to hundreds of other plants.
According to this morning's Bogota newspaper, "El Tiempo", nobody knows the root cause of yesterday's outage. Immediately, the country's leftist rebels were blamed, but now the leading theory is that it was initiated byoperator error (a technician touching something he shouldn't have), and then propagated by a faulty distribution system.
Another example of the need for a robust and resilient infrastructure, and appropropriate business continuity plans.
We had a great event today! This was a first-of-a-kind product launch, using Second Life as the medium. We invited IBM Business Partners, industry analysts and reporters from the Press to have their "avatars" in-world to watch us launch new tape systems, archive and retention systems, and disk systems announced this month.
Andy Monshaw, IBM System Storage General Manager, welcomed everyone to the event, and introduced our three speakers.He mentioned that this was a great innovative way to meet, collaborate and forge relationships without the carbon pollution associated with travel required by a more traditional face-to-face meeting. We had attendees from the USA, UK, Germany, Sweden, Italy, Colombia, and Brazil.
All the attendees were given a "goody bag" that contained IBM BP-logo clothing, animations and gestures to be used during the meeting.
Eric Buckley, one of our marketing managers for tape systems, introduced our complete line of LTO 4 tape systems, as wellas the TS7520 Virtualization Engine, a virtual tape library for Windows, UNIX and Linux servers. Eric had a virtual 3-Dversion of an LTO cartridge that is photo-realistic and dimensionally correct.
Funda Eceral, our solutions manager for archive and retention offerings, presented the new version of the IBM System Storage DR550, the DR550 file system gateway, and the IBM System Storage Multilevel Grid Archive Manager. At first we thought we would "pass the microphone" from speaker to speaker, but it turned out to be easier just to give all three speakers their own microphone.
Last, but not least, was David Tareen, marketing manager for disk systems, covering the entry-level DS3000 Express disk system bundles designed for our SMB client. David used a black-and-brown pointer stick to point out specific things on the charts.
After the presentations, Kristie Bell, VP of Marketing for IBM System Storage, hosted a Question & Answer (Q&A) panel.Avatars rose their left hand to indicate they had a question.
We thought it would be a good idea to have a few minutes at the end to socialize over a cup of coffee. This involved making a "coffee machine" that dispensed coffee, and the appropriate animations and gestures so that everyone could sip the coffee, and hold the coffee at waist level when they were talking.
The event was held upstairs in one of the conference rooms of the IBM Briefing Center, located on "IBM 8" island.Many people went to the ground floor to look at the many IBM System Storage products on display. Unlike a picture on a web-page, Second Life gives you a 3-D view that you can walk around each product, and get a feel for the size and shape of the hardware.
If you missed the event, you can still visit the IBM Briefing Center. Here is the SLURL:http://slurl.com/secondlife/IBM%208/114/242/23/
We had four photographers and camera-persons on hand to capture still shots, video, audio, and chat text, and are working now to combine them for marketing collateral. I want to thank the builders, script programmers, animators, clothing designers, speakers, editors, and channel enablement team for making this event such a great success!
