Next Monday, September 1, 2008, marks my two year "blogoversary" for this blog!
I won't be blogging on Monday, of course, because that is [Labor Day] holiday here in the United States.
(From a Canadian colleague: US is not the only country who celebrates Labor Day on the first weekend in September. Canada also celebrates Labour Day on the first weekend in September. It's the only holiday(other than Christmas/New Years) where we are in sync with US. Our Thanksgiving Days are different as is your July 4 vs our July 1. But for Labour Day we are one with the Borg...)
(From an Australian colleague: each province of Australia has its own day to celebrate Labor Day, see [Australia Public Holidays])
The rest of the world celebrates Labor Day on May 1, but the USA celebrates this on the first Monday of September, which this year lands on September 1.Originally, the day is intended to be a "day off for working citizens", IBM is kind enough to let managers and marketingpersonnel have the day off also. (Not that anyone is going to notice no press releases next Monday, right?)
I started this blog on September 1, 2006 as part of IBM's big["50 Years of Disk Systems Innovation"] campaign. IBM introduced the first commercial disk system on September 13, 1956 and so the 50th anniversary was in 2006. Last year, IBM celebrated the 55th anniversary of tape systems.
Several readers have asked me why I haven't talked about recent current events, such as the Olympic Games in Beijing, or the U.S. National Conventions for the race for U.S. President. I have to remind them of one of the key precepts of IBMblogging guidelines:
8. Respect your audience. Don’t use ethnic slurs, personal insults, obscenity, or engage in any conduct that would not be acceptable in IBM’s workplace. You should also show proper consideration for others’ privacy and for topics that may be considered objectionable or inflammatory - such as politics and religion.
I made subtle references to my senator from Arizona, John McCain, in my post [ILM for my iPod], and to Barack Obama in my post [Searching for matching information]. I don't think anyone would mind that I send a "Happy Birthday!" wish to both of them.Senator McCain turns 72 years old today, and Senator Obama turned 47 years old earlier this month.
And lastly, Tucson itself [celebrates this entire month] its 233rd birthday. That's right,Tucson, the 32nd largest city of the USA, and headquarters for IBM System Storage, is older than the USA itself.While the Tucson area has been continuously inhabited by humans for over 3500 years, it officially became Tucsonon August 20, 1775.
Fellow blogger Justin Thorp has opined that [blogging is like jogging]. Somedays, you are just too busy to do it, and other days, you make time for it, because you know it is important.For the record, it is not my job to blog for IBM, that ended last September 2007. I continue to blog anyways because I have benefited from it, both personally and professionally.I want to thank all of you readers out there for making this blog a great success! Being named one of the top 10 blogs of the IT storage industry by Network World, two back-to-back Brand Impact awards from Liquid Agency, and recently earning a "31" Technorati ranking, has really helped keep me going.
So, I look forward to next month, and beginning my third year on this blog. I am sure there will be lots of surprises and announcements you can all look forward to in the next coming weeks and months that I will have plenty to write about.
(Note: The following paragraphs have been updated to clarify the performance tests involved.)
This time, IBM breaks the 1 million IOPS barrier, achieved by running a test workload consisting of a 70/30 mix of random 4K requests. That is 70 percent reads, 30 percent writes, with 4KB blocks. The throughput achieved was 3.5x times that obtained by running the identical workload on the fastest IBM storage system today (IBM System Storage SAN Volume Controller 4.3),
and an estimated EIGHT* times the performance of EMC DMX. With an average response time under 1 millisecond, this solution would be ideal for online transaction processing (OLTP) such as financial recordings or airline reservations.
(*)Note: EMC has not yet published ANY benchmarks of their EMC DMX box with SSD enterprise flash drives (EFD). However, I believe that the performance bottleneck is in their controller and not the back-end SSD or FC HDD media, so I have givenEMC the benefit of the doubt and estimated that their latest EMC DMX4 is as fast as an[IBMDS8300 Turbo] with Fibre Channel drives. If or when EMC publishes benchmarks, the marketplace can make more accurate comparisons. Your mileage may vary.
IBM used 4 TB of Solid State Disk (SSD) behind its IBM SAN Volume Controller (SVC) technology to achieve this amazing result. Not only does this represent a significantly smaller footprint, but it uses only 55 percent of the power and cooling.
The SSD drives are made by [Fusion IO] and are different than those used by EMC made by STEC.
The SVC addresses the one key problem clients face today with competitive disk systems that support SSD enterprise flash drives: choosing what data to park on those expensive drives? How do you decide which LUNs, which databases, or which files should be permanently resident on SSD? With SVC's industry-leading storage virtualization capability, you are not forced to decide. You can move data into SSD and back out again non-disruptively, as needed to meet performance requirements. This could be handy for quarter-end or year-end processing, for example.
"IBM says revenue for its mainframe business rose 32% in the second quarter compared with a year earlier, easily outpacing overall sales growth of 13%.A big driver was February's launch of IBM's next-generation mainframe line, the z10, its first big upgrade since 2004. IBM spent about $1.5 billion on the new line.
With their power and size, mainframes have some unique advantages over (distributed) servers. Many companies cobble together many servers, powered by industry standard chips made by Intel (INTC) and Advanced Micro Devices, (AMD) to do jobs that were once the province of mainframes. IBM, too, sells such servers.
IBD: Can you tell me more about this business?
Gelardi: Traditionally, the mainframe was the back-office powerhouse for batch and transactional processing — sort of the thing behind banks, the thing behind retailers, the thing behind insurance companies.
It's the thing that, if you screw this up, you just gave your whole business away. The new thing, which is really sort of the second driver of growth, is the introduction of Linux (an open-source operating system popular with some servers) on the mainframe. Z-Linux (IBM's Linux mainframe software) is where we have been able to drive substantially new workloads to the mainframe.
IBD: Why is the mainframe business important to IBM?
Gelardi: It's a very differentiated product environment where we feel very confident that we can say to a client, look, we built this thing from the casters all the way up; the software stack, all the way up. We've built into this a level of performance and scalability and efficiency. We're very, very confident that we can resolve any issue (for customers).
Let me give you an example. If I take (1,500 Intel) servers . . . and put them on a single mainframe, I'll have no performance problems whatsoever. But I'm taking all of that workload that was on 1,500 separate servers and consolidating them on one mainframe. While it may be a million-dollar machine and up, it's actually cheaper than those 1,500 servers.
IBD: What are some big drivers for your clients today?
Gelardi: Energy. If you look at a workload on a previous generation mainframe, z9, for the equivalent performance on a z10, I'm going to use 15% less energy for the same amount of performance.
Look at the (physical data-center space) in the industry. The question used to be, "How much space do you want?" The question now is, "How much energy are you going to consume?" It's more efficient to manage the work loads inside the larger (mainframe).
IBD: So, you're saying that using a mainframe addresses these modern problems better than servers?
IBD: Is it hard to convince people of that?
Gelardi: It's a legitimate question for clients who never had a mainframe. There are a few. (In those cases) it will probably be more complicated (to convince them).
However, a year or so ago we put out a press release about an entertainment (company). Their story was, "We're going to build a new gaming environment." Long story short, they said, "Why not use the mainframe?" There are new clients coming to the mainframe.
IBD: Do mainframes help other IBM businesses?
Gelardi: Clearly. I have very broad coverage. We are the server vendor. We have the storage capacity; we have the operating environment; we have the software stack, (including) Websphere, Tivoli, DB2. We have the services capabilities. We have the consulting capability. You can sort of go on. It becomes an ecosystem that is really valuable to the company at large.
IBD: What mainframe customers were active in the second quarter?
Gelardi: Interesting enough (given the state of the industry), the financial services sector was very strong. That was particularly true in the Americas and in Europe. We have a pretty broad spread (of users), but there is no question that financial services is a core market."
IBM offers a lower total cost of ownership (TCO) than HP or Sun can offer. For more about the IBM System z10 EC, see my posts last month:
If you missed the [IBM System Storage and Storage Networking Symposium] in San Diego, California last month (like I did because I was in Japan and India), here is your chance to attend the one next month in Europe, September 8-11, in beautiful[Montpellier, France]. Several of my colleagues from the IBM Tucson Executive Briefing Center are scheduled to speak at this event.
And maybe, perhaps, some IBM executives, will have something important to say next month also! Stay tuned!
For a list of other IBM events this year, see the [2008 schedule].
The comic combines the recent popularity in cookbooks to help parents get their children to eat morevegetables, such as Jessica Seinfeld's [Deceptively Delicious: Simple Secrets to Get Your Kids Eating Good Food], with the popularity of the latest Batman movie, [The Dark Knight]. To be fair, I have not reviewed the recipe book,but certainly being the wife of comedian Jerry Seinfeld and mother of his children sufficiently qualifies her to write such a book. I did have the pleasure to see this movie at an IMAX movie theater in Hartford, CT a few weeks ago. I highly recommend it. (See also my friend Pam's awesome [review of this movie]).Some have argued the movie franchise has "gone dark" from the previous Batman movies and may not be appropriatefor children. Hiding vegetables in meals may not the right thing for children either.
Unlike IBM that repeatedly delivers unique and innovative new products to the marketplace, Microsoft pulls theold ["bait and switch"] routine. In a series of hiddencamera interviews, Microsoft asks skeptical people who have never used Microsoft Vista operating system their opinions.As expected, all express concerns of problems they have heard about Microsoft's new OS, from friends, colleagues or Apple television advertisements. On a scale of 0 (won't touch it) to 10 (can't wait to have it), the averageskeptic rated Vista with a paltry 4.4 score.
The Microsoft interviewers then show them the new "Microsoft Mojave" Operating System, and askthese same skeptics for their opinions, of which many (35 out of 140 by one account) express they like it, find this new OS usefuland intuitive. The interviewers then explain that this Mojave OS was nothing more than the existing Vista OS alreadyin the marketplace. The average rating for Mojave OS was a significantly higher 8.5 score.Just like hiding spinach in a meal to get your kids to eat it. They tricked you, and you saidyou liked it!
Perhaps the key take-away is whom should prospective customers listen to when evaluating a new product. Microsoftis reasonable in feeling that customers should not base their opinions about Vista solely on lopsided Apple televisioncommercials. Apple, Inc. is one of Microsoft's primary competitors. I feel, however, that if you have friends or colleagues who have shared with you their hands-on experiences, that indeed should have much higher weighting.
Nothing, of course, beats personal experience. If you want to try out one of IBM's latest products for yourself, please contact your local IBM Business Partner or IBM sales representative.
Once again it's Tuesday, which means IBM announcement day!
Today IBM announced [two new DS3400 SAN Express Models]. These two new models will replace the IBM System Storage DS3400 SAN Express Kit model 41U and 42U to be withdrawn from marketing today. The DS3000 series of scalable, flexible, and affordable storage solutions support IBM System x, System p, and BladeCenter servers.
Two new IBM System Storage DS3400 SAN Express Kits are being introduced that provide the parts needed to setup and configure a SAN with the exception of a SAN switch that can be ordered separately. The IBM System Storage DS3400 SAN Express Kits contain Emulex EZPilot software that enables automated installation and configuration of the SAN components. IBM System Storage DS3400 SAN Express Kits models 41S and 42S and Emulex EZPilot software work in conjunction with the IBM TotalStorage SAN16B-2 Express Model Switch which comes with eight ports and eight 4 Gbps SFPs. The EZPilot software can support configurations with either one or two SAN16B-2 switches.
The 41S is a single-controller model DS3400 with two HBA cards and four cables. The 42S is the dual-controller model with two HBA cards and eight cables.

The quote above applies to blogs as well. Those about competitive products of which the blogger has little to no hands-on experience tend to be terribly misleading or technically inaccurate. We saw this last month as Sun Microsystems' Jeff Savit tried to discuss the IBM System z10 EC mainframe.
This time, it comes from EMC bloggers discussing NetApp equipment, and by association, IBM System Storage N series gear.I was going to comment on the ridiculous posts by fellow bloggers from EMC about SnapLock compliance feature on the NetApp, but my buddies at NetApp had already done this for me, saving me the trouble.
The hysterical nature of writing from EMC, and the calm responses from NetApp, speak volumes about the culturesof both companies.
The key point is that none of the "Non-erasable, Non-Rewriteable" (NENR) storage out there are certified as compliant by any government agency on the planet. Governments just aren't in the business of certifying such things. The best you can get is a third-party consultant, such as [Cohasset Associates], to help make decisions that are best for each particular situation.
In addition to SnapLock on N series, IBM offers the [IBM System Storage DR550], WORM tape and optical systems, all of which have been deemed compliant to the U.S. Securities and Exchange Commission [SEC 17a-4] federal regulations by Cohasset Associates. For medical patient records and images like X-rays, IBM offers the Grid Medical Archive Solution [GMAS]designed to meet the requirements of the U.S. Health Insurance Portability and Accountability Act[HIPAA].For other government or industry regulations, consult with your legal counsel.
I was warned that this musical would be nearly three hours long, that the singing and dialogue would be in Hindi language, and there would be no English subtitles. I don't speak Hindi, and would not be able to understand a single word the actors said.
How bad could it be?
Despite the fact that there were nearly 20 members in the cast, the story jumps back and forth in both place and time, with some dream sequences thrown in for cinematic effect, I was able to understand quite a bit. I thoroughly enjoyed this movie! Perhaps its a sign of a good movie that you can understand most of it purely from the visual aspects.
The same can be said for presentations that you give in foreign countries. Both in Japan and India, I had plenty of visuals to complement the text on the page, and the words that I spoke. Shawn over at [Anecdote] blog points to this greatpresentation by Garr Reynolds, author of [Presentation Zen]. The slide deck below has some key takeaways and quotes from Dr. John Medina's latest book "Brain Rules" that apply to presentations.
