Well, it is Halloween
back in the USA. I am in Seoul Korea this week, so it is already Thursday, November 1st here, but thought I would comment on Colin Barker's piece in ZDnet
titled[SNW offers the frights
].The article starts out with an oversimplification:
The storage industry is enjoying a boom currently thanks to the requirement for IT managers to keep everything. With the possibility of being sued any time by any company for no good reason at all, everyone is keeping everything, or at least all their data. Result? Loads and loads more kit being bought to the benefit of EMC, IBM, HP and every other supplier with any kind of storage product.
While its true that IBM System Storage grew yet again in 3Q07, exceeding our own internal business model, I would not call this an overall "boom" for the storage industry. While companies are growing in "TB capacity" by 30-50%, this translates only to single digit growth in terms of "Dollar revenues". This is because we continue to make storage with declining dollar-per-GB.
One should not confuse what people do with what people are required to do. I am not a lawyer, but most regulations pertaining to storage of information state that certain records need to be kept for a set amount of time, either a fixed period of years, or based on some event. For example, broker/dealers need to keep emails of their clients for six years after the client closes their brokerage account. After those six years, the records can be destroyed.
Unfortunately, many IT managers look at the laws and come up with the simplest solution: keep everything forever. While this might meet the regulators audit requirements, it does expose their employer to subpoenas for data that should have been deleted, and may not be very cost-effective.
The alternative for many IT managers involves having to leave their comfort zone, and talk to their legal counsel, the lines of business, and try to classify their data, determine a set of policies, and inact some forms of enforcement. This is perhaps the "scary" part of the storage of information, it has grown outside the walls of IT, forcing IT managers to interact with the rest of the business to get their jobs done.
Compliance is the only game in town and that is most certainly where the money is.
Anytime an analyst tells you that something is the "only game in town", they are usually wrong. In this case, IBM has had great success in other areas that are not compliance-related. For example, digital video surveillance (DVS) is being used not only to help reduce shoplifting, but also to help identify patterns in customers perusing through aisles and window-shopping. Identifying what people are interested in has proven effective in moving product displays around to better attract buyers and motivate them to make purchases.
Take, the keynote from Andy Monshaw, general manager of IBM storage, and thus a man who is very much in a position to know. He spent his allotted 30 minutes, or whatever, listing all the security, compliance, threats and related issues that are currently making the jobs of most IT manager a cause for concern. Now, there is an argument that suggests that it is absolutely the right thing to do to frighten IT managers into sorting out their issues. They need shaking up say some. Especially analysts.
I helped develop the content of Andy's SNW presentation, working with his speech writers and graphic artists to make a consistent and coherent message fit in the 25 minutes he was given. The challenge with SNW is that we needed to make this presentation applicable across the entire storage industry, without sounding like an infomercial for IBM offerings.
Some people have compared the storage to the "insurance industry", claiming that backups, remote disk mirroring, continuous data protection and other storage related features are costs that can be compared to insurance you pay to protect your home, business, and other assets. You hope you never have to use it, and complain how much it costs, but when bad things happen, you hope it is the best money can buy.
Unlike Y2K, which was a one-time event that had a specific date of occurrence, the threats and risks mentioned by Andy in his presentation may never happen at all, or in other cases, may happen more than once, without knowing when or where. For the sake of your shareholders, and your stakeholders, it is best to be prepared for these possibilities.
The counter argument says that IT companies just smell the money.
Is this a counter argument? Can IBM not both help customers mitigate their risks, and at the same time, turn a profit? Trust me, you do not want to do business with any storage vendor that is not interested in making a profit. The better ones have incorporated addressing client's most pressing challenges into their strategy. I gave a quick summary of IBM's strategy last August in [Day 1 Storage Symposium].
Helping our clients mitigate risks is just one of IBM's core strengths. If you want to learn more, contact your local IBM Business Partner or storage rep.

Well it's Tuesday, which means its time to look at recent announcements.While I was on vacation last week, IBM made a lot of storage announcements October 23.Josh Krischer gives his summary on WikiBon [October 2007 Review
].Austin Modine of the The Register
went so far as to say that [IBM goes crazy with storage system updates
- IBM System Storage DS8000 series
This is "Release 3" software/microcode upgrades on our existing "Turbo" hardware.
- IBM FlashCopy SE -- Here "SE" stands for Space Efficient. Rather than allocating a full 100% of the space for the FlashCopy destination, you can set aside just a fraction, and this will hold all the changed blocks, similar to whatIBM already offers on the DS4000 series.
- Dynamic Volume Expansion -- In the past, if you needed more space for a LUN, you had to carve out a newer one elsewhere, and then copy the data over from the old to the new, leaving the old LUN around to be re-used or leftstranded. With this enhancement, you can just upgrade the LUN in place, making it bigger as needed, similar to whatIBM already offers on the DS4000 series and SAN Volume Controller. This applies to CKD volumes for the System zmainframe users out there as well.
- Storage Pool Striping -- striping volumes across RAID ranks to eliminate or reduce hot-spots, and provide betterload balancing. Many used SAN Volume Controller in front of the DS8000 to do this, but now you can do it natively inthe DS8000 itself.
- z/OS Global Mirror Multiple Reader -- for System z customers, "z/OS Global Mirror" is the new name for XRC. Thisenhancement improves the throughput of sending updates to the remote disaster recovery location.
- DS Storage Manager enhancements, the element manager software has been enhanced, and is pre-installed on the new IBM System Storage Productivity Center, which I will talk about below.
- Intermix of DS8000 machine types -- this is especially useful to allow new frames to have co-terminating warrantieswith the base units. In other words, as you expand your system, you can ensure that the entire chunk of iron runs outof warranty all at the same time, to simplify your decision making process to upgrade or contract for extended service.
See the [DS8000 Announcement Letter] for more details.
- IBM System Storage SAN Volume Controller 4.2.1
BarryW summarizes the updates in the[Announced SVC 4.2.1] release.If you have problems with the link he provides in his post, here is the [SVC 4.2.1 Announcement Letter].
- IBM System Storage Productivity Center
One of the biggest complaints about IBM TotalStorage Productivity Center is that it is software that needs to beinstalled on its own server, and that this installation process can take a day or two. Why wait? Now you can havea hardware console that has the DS8000 Storage Manager software, SVC Admin Console software, and IBM TotalStorageProductivity Center "Basic Edition" pre-installed. Here are the key features.
- Pre-installed and tested console
- DS8000 R3 GUI integration
- Cohabitation of SVC 4.2.1 GUI and CIMOM
- Automated device discovery
- Asset and capacity reporting, including tape library support
- Device configuration
- Advanced topology viewer
See the[System Storage Productivity Center - Announcement letter] for more details."Basic Edition" can be upgraded to "Standard Edition" to get full functionality.
- IBM System Storage N series
Our "Release 9" applies across the board, from N3000 to N5000 to N7000 series models, includingnew host bus adapters, and the new Data OnTAP 7.2.4 release level.
The Virtual File Manager (VFM) was announced as one of our latest [Storage Virtualization Solutions]. VFMprovides a global namespace that aggregates the file systems from Linux, UNIX, and Windows file servers, as well asN series storage, into a consolidated environment.
See the [N series Announcement Letter] for more details.
- IBM TS7520 Virtualization Engine
IBM's virtual tape library (VTL) for the distributed systems platform, has been enhanced to provide:
- Up to 12TB of disk cache, using 750GB SATA disk.
- F05 Tape Frames installed as TS7520 base units through a 32 port fibre channel switch
- Support for LTO generation 4 tape drives, both as virtual tape drives and as physical tape drives within IBM automated tape libraries attached to the TS7520. This allows you to use Encryption capabilities of LTO4.
See the [TS7520 Announcement Letter] for more details.
- IBM System Storage DS6000 series
The latest 300GB 15K RPM drives are now supported.
- IBM System Storage DS4000 series
This was a software/microcode upgrade release for the DS4000 series.
- RAID-6 support on the DS4700 Express models and the DS4200 Model 7V
- Support for greater than 2 TB volumes on selected supported operating systems
- 8K cache block size
- DS4000 Storage Manager v10.10 increases the number of FlashCopy tasks, remote mirror pairs, and storage partitions.
See the [DS4000 Announcement Letter] for more details.
- IBM System Storage DS3000 series
DS3000 series now supports SATA disk, and can be attached to AIX and Linux on System p servers. This appliesto the DS3200, DS3300 and DS3400 models.See the [DS3000 Announcement Letter] for more details.
- IBM System Storage TS2240
These are LTO4 Half-High drives, which can support encryption.See the [TS2240 Announcement Letter] for details.
Perhaps Austin is right, we might have gone crazy announcing all of this at once.

Well, I'm back from my relaxing vacation in New Zealand and Fiji. Yes, we hada few earthquakes near Milford Sound, several avalanches that blocked some roads, a few power outages, and we walked in a rain storm for three hours after our bus broke down. But overall, it was fun.
This week I am in Seoul, South Korea for various business meetings. The best part is that I am almost already acclimated to the time zone, since New Zealand was GMT+11 and Fijiwas GMT+12, I am hoping that I will adjust fast this week.
South Korea is part of our "BRICK" countries--those emerging markets made up of Brazil,Russia, India, China and Korea that represent IBM's spearhead into the SMB marketplace.[Read More]
I'm off for two weeks of vacation.
Here's a quick round-up of things I saw this week that didn't have time to blog about:
- Vice President Al Gore won the Nobel Peace Prize for this hard work on "going green"to help save the planet. IT datacenters can, and should, do more to help in this area.
- SNW conference in Dallas. I won't be there, but have been helping out behind the scenes.
- SNW conference in Germany later in October. I won't be there either, but look forAndy Monshaw, General Manager of System Storage, to give the keynote address.

Two European scientists, Albert Fert (France) and Peter Grunberg (Germany) have won the 2007 Nobel Prize for physics for their research into Giant Magnetoresistance, or GMR. GMR read/write heads are used in IBM disk systems.
Chris Evans points to an interesting "jet analogy" in his post[Your Data On a Knife Edge].To help people understand that significance of this innovation, IBM Research has a website with all kindsof useful GMR information: http://www.research.ibm.com/research/gmr.html
While many people associate GMR heads with disk drives, it also applies to tape.In 2006, IBM Researchers Set World Record in Magnetic Tape Data Density, recording 6.67 billion bits per square inch of tape media. This was achieved with specific developments:
- New high-density dual-coated particulate magnetic tape: Developed by Fuji Photo Film Co., Ltd., in Japan in collaboration with IBM Almaden researchers, this next-generation version of its NANOCUBIC™ tape uses a new barium-ferrite magnetic media that enables high-density data recording without using expensive metal sputtering or evaporation coating methods.
- More sensitive read-write head: For the first time, magnetic tape technology employs the sensitive giant-magnetoresistive (GMR) head materials and structures used to sense very small magnetic fields in hard disk drives.
- GMR servo reader: New GMR servo-reading elements, software and fast-and-precise positioning devices provides an active feedback system with unprecedented 0.35-micron accuracy in monitoring and positioning the read-write head over the 1.5-micron-wide residual data track.
- Improved tape-handling features: Flangeless, grooved rollers permit smoother high-speed passage of the tape, which also enhances the ability of the head to write and read high-density data.
- Innovative signal processing algorithms for the read data channel: An advanced read channel used new "noise-predictive, maximum-likelihood" (NPML) software developed at IBM's Zurich Research Laboratory to process the captured data faster and more accurately than would have been possible with existing methods.
IBM often leverages the research done in one part of its business over to other parts of its business. In this manner, advances in disk translate into advances in tape, keeping tape a viable medium for at least the next 8-10 years.

As BarryW points out, IBM System Storage SAN Volume Controller (SVC) is now[fully certified with VMWare ESX 3.0.2
]. Here's the [official IBM press release
]. This is based onthe [Storage Virtualization Certification Program
] announced by VMware last week.
This is great news for everyone. I have said before that VMware is perhaps the best product EMC offers, and some EMC bloggers have returned the favor saying that SVC might just be the best disk system that IBM offers. While IBM and EMCare heavily competitive in other aspects of the IT storage industry, when it comes to delivering what is right for the customer, we can set aside those differences. IBM is the number one reseller of VMware, and it is a great pairing with SAN Volume Controller.
Of course, it is not a free-for-all. VMware has a few restrictions at this time:
- storage hardware
Disk managed by SVC must be on VMware's [Storage / SAN Compatibility GuideFor ESX Server 3.x]. As VMware certifies future storage that SVC supports, they will update the guide accordingly.
- guest operating systems
The VMware certification is limited to Windows operating system, specifically those listed on its [Guest OS Guide].The list looks fairly extensive, so if you were running Windows guests on VMware to SVC today via RPQ,you are probably covered. However, if you are running NetWare or Linux, then the VMware certification doesnot yet apply.
- host bus adapters
Only Qlogic host bus adapters are supported at this time. This is because VMware directly communicates to the host bus adapters as part of its "I/O virtualization" capabilities, and needs to work with or test with all the other HBA manufacturers.
- no RDM support
Raw Device Mapping (RDM) mode is currently not yet supported. This probably will only affect a small percentage of customers, as I don't know of any major applications that require this.
Of course, most of these issues can probably be addressed with additional testing, or minor software changes, and IBM will work with VMware to prioritize what added testing or software changes are needed to expand this support.

Welcome to my blog on IBM Developerworks!
I am Tony Pearson, storage consultant at the IBM Executive Briefing Center, located in Tucson, Arizona. I have degrees in Computer Engineering and Electrical Engineering from the University of Arizona. Over the past 20 years, I have worked in a variety of storage roles, including development projects, product and portfolio management, testing, field support, marketing, and now am doing storage consulting.
There are a lot of things to discuss related to storage, and I am never short of opinions. As such, the standard IBM disclaimer applies: “The postings on this site solely reflect the personal views of the author and do not necessarily represent the views, positions, strategies or opinions of IBM or IBM management.”
I have invited other IBMers to post their opinions, and when they do, their opinions may not necessarily match mine either.
This is an open two-way conversation between IBM, Business Partners, Independent Software Vendors, prospect and existing clients. I encourage everyone to post comments about our products, services, and marketing efforts.
I welcome HDS into the "Super High-End" club. Those who follow my blog might remember thatI suggested that analysts like IDC that use "Entry Level", "Midrange" and "Enterprise" as categoriesmay need a New Category: Super High End
I was not surprised to see EMC, who now drops further down in perception, dispute HDS's recent SPC-1 benchmarks.Fellow blogger EMC's BarryB posted on his Storage Anarchist blog [IBM vs. Hitachi] thatpoints out that IBM's SAN Volume Controller (SVC) is still much faster, and less expensive, than USP-V.
So, just in case you haven't seen all the press releases, here is a quick recap on the results:IBM SVC 4.2 is still in first place, then HDS USP-V, then IBM System Storage DS8300. Just for comparison, I includeour IBM System Storage DS4800 midrange disk results, so you can appreciate the difference between midrange and high-end.There are other products from other vendors, I just point out a few from IBM and HDS here in this graph.
******************************************************************** 272,505 IOPS - IBM SVC 4.2
************************************************** 200,245 IOPS - HDS USP-V
******************************* 123,033 IOPS - IBM DS8300
*********** 45,014 IBM DS4800
HDS tried to come up with a phrase "Enterprise Storage System" for comparison that would leave the SVC 4.2 out.Given that the SVC has five nines (99.999%) availability, has non-disruptive upgrade and firmware update capability, has more than two processors typical of midrange products, and can connect to mainframes via z/VM, z/VSE andLinux on System z operating systems, there is no reason to pretend SVC isn't Enterprise-class.
The irony now is that EMC now looks very lonely being one of the last remaining major storage vendors not to participate in standardized benchmarks that help customers make purchase decisions, as mentioned both by IBM's BarryW: I guess that only leaves EMC, as well as HDS's Claus Mikkelsen: Olympics of Storage.
Earlier this year, EMC's Chuck Hollis opined[Storage Scorecard]that the EMC DMX and HDS TagmaStore USP were high-endboxes, which I would speculate both of these would fall somewhere between DS4800 and DS8300 on the graph above.If that is the case, it is impressive that HDS was able to re-engineer their USP-V to be 2-3x faster thanits predecessor, the USP.
Not all workloads are the same, and your mileage may vary. While I can't speak to HDS, the folks over atEMC have assured me, in writingcomments on this blog, that there is nothing preventing their customers from publishingtheir own performance comparisons between EMC and non-EMC equipment. I would encourage every customer to do this, between IBM and HDS, HDS and EMC, and between IBM and EMC, to help shed even more light on this area.In fact, you can even run your own SPC benchmarks to see how your own environment compares to the ones published.
Of course, performance is just one attribute on which to choose a storage vendor, and to choose specific products,models or features. For more information about Storage Performance Council and the SPC-1 and SPC-2 benchmarks,see my week-long series on SPC benchmarks, which are listed in reverse chronological order.
Go to the official Storage Performance Council website to read the details of the SPC-1 results.

Byte and Switch magazine published an article on Top Women in Storage
I thought of this as it was recently announced that Cindy Grossman, IBM VP of Tapeand Archive systems, will also serve as Site Level Manager for the IBM Tucson lab.
The motivation for the Byte and Switch article was probably from this article in Wall Street Journal detailingthe status of women in IT sales positions. Here is an excerpt:
Today, 13.5% of EMC's sales force is female, the company says, compared with 40% at International Business Machines Corp. and 29% at CA Inc., a big software vendor, those companies say. According to the 2000 U.S. census, about 25% of high-tech employees nationally were women.
IBM recognizes that diversity provides unique advantages in dealing with a global marketplace. Not only are women well represented on our IT sales force, they are also well represented on our board of directors, our Worldwide Management Committee, and our executive team overall, as well as in technical positions such as IBM Fellows, Distinguished Engineers, members of the IBM Academy of Technology. Working Mother magazine has rated IBM one of the top 10 "Best Companies" for women to work for in each of the 18 years that it has published this list.
In 2006, 51 camps called EXITE (Exploring Interests in Technology and Engineering) were held worldwide in 33 countries. The hope is to get young girls to pursue college degrees in computer science, math and engineering, so that they can then help fill the shortage of technical resources in IT.
So, if you are a women discouraged at your current place of employment, and are looking for exciting new opportunities in IT, come check out working for IBM![Read More]
Over the past year and a half, I have been focused on explaining WHAT
IBM System Storage was, and WHY
IBM should be considered when making a storage purchase decision. Let's recapsome of IBM's accomplishments during this time:
Today, October 1, I switch over to HOW to get it done. In my new job role, I will be leading a seriesof projects and workshops on how to make your data center more green, how to get more value from the information you have, how to better protect your information from unauthorized access or unethical tampering, how to develop and deploya site-wide business continuity plan, and how to centralize your management using open industry standards.
I will still be in Tucson, but am moving from building 9032 over to 9070 to be closer to the rest of my team.
If you are interested in participating in such a workshop, contact theTucson Executive Briefing Center.
