Wrapping up my week in China, I read an article by Li Xing in the local "China Daily" about energy efficiency in buildings. She argues that it is not enough for a building to be energy-efficient on its own, but you have to consider the impact of the other buildings around. Does it reflect the sun so harshly into neighboring windows that people are forced to put up blinds and use artificial light? Does it block the sun, so that rooms that previously could be used with natural sunlight must now be artificially lit?
A similar effect happens with power and cooling in the data center. Servers and storage systems generate heat, and that heat affects all the other equipment in the data center. IBM has the most power-efficient and heat-efficient servers and storage, but that is not enough. You have to consider the heat generated by all systems that might raise overall temperature.
This is what motivated IBM to deliver the IBM Rear Door Heat eXchanger, a member of IBM's CoolBlue(tm) portfolio.
According to a press release:
Research has indicated that water can remove far more heat per volume unit than air. For example, in order to disperse 1,000 watts, with 10 degree temperature difference, only 24 gallons of water per hour is needed, while the same space would require nearly 11,475 cubic feet of air. IBM's Rear Door Heat eXchanger helps keep growing datacenters at safe temperatures, without adding AC units. The unobtrusive solution brings more cooling capacity to areas where heat is the greatest -- around racks of servers with more powerful and multiple processors.
The CoolBlue portfolio of IBM innovations includes comprehensive hardware and systems-management tools for computing environments, enabling clients to better optimize the power consumption, management and cooling of infrastructure at the system, rack and datacenter levels. The CoolBlue portfolio includes IBM PowerConfigurator, PowerExecutive, and Rear Door Heat eXchanger.
The eXchanger works on standard 42U racks, and can help clients deal with the rapid growth of rack-mounted servers and storage on their raised floor. How cool is that!

In Storage Technology News, Marc Staimer makes hisSeven network storage predictions for 2007
. Let's take a closer look at each one.
- Federal Rules for Civil Procedures (FRCP) will increase adoption of unstructured data classification, email archive systems and CAS.
CAS continues to flounder, but the rest I can agree with. Regulations are being adopted world wide. Japan has its own Sarbanes-Oxley (SOX) style legislation go into effect in 2008.IBM TotalStorage Productivity Center for Data is a great tool to help classify unstructured file systems. IBM CommonStore for email supports both Microsoft Exchange and Lotus Domino, and can be connected to IBM System Storage DR550 for compliance storage.
- Unified storage systems (combined file and block storage target systems) will become increasingly attractive in 2007, because of their ease of use and simplicity.
I agree with this one also. Our sales of IBM N series in 2006 was great, and looking to continue its strong growth in 2007. The IBM N series brings together FCP, iSCSI and NAS protocols into one disk system. With the SnapLock(tm) feature, N series can store both re-writable data, as well as non-erasable, non-rewriteable data, on the same box. Combine the N series gateway on the front-end with SAN Volume Controller on the back-end, and you have an even more powerful combination.
- Distributed ROBO backup to disk will emerge as the fastest growing data protection solution in 2007.
IDC had a similar prediction for 2006. ROBO refers to "Remote Office/Branch Office", and so ROBO backup deals with how to back up data that is out in the various remote locations. Do you back it up locally? or send it to a central location?Fortunately, IBM Tivoli Storage Manager (TSM) supports both ways, and IBM has introduced small disk and tape drives and auto-loaders that can be used in smaller environments like this. I don't know whether "backup to disk" will be the fastest growing, but I certainly agree that a variety of ROBO-related issues will be of interest this year.
- 2007 will be remembered as the year iSCSI SAN took off because of the much reduced pricing for 10 Gbit iSCSI and the continued deployment of 10 Gbit iSCSI targets.
While I agree that iSCSI is important, I can't say 2007 will be remembered for anything.We have terrible memory in these things. Ask someone what year did Personal Computers (PC) take off, and they will tell you about Apple's famous 1984 commercial. Ask someone when the Internet took off, cell phones took off, etc, and I suspect most will provide widely different answers, but most likely based on their own experience.
For the longest time, I resisted getting a cell phone. I had a roll of quarters in my car, and when I needed to make a call, I stopped at the nearby pay-phone, and made the call. In 1998, pay phones disappeared. You can't find them anymore. That was the year of the cell phones took off, at least for me.
Back to iSCSI, now that you can intermix iSCSI and SAN on the same infrastructure, either through intelligent multi-protocol switches available from your local IBM rep, or through an N series gateway, you can bring iSCSI technology in slowly and gradually. Low-cost copper wiring for 10 Gbps Ethernet makes all this very practical.
Another up-and-coming technology is AoE, or ATA-over-Ethernet. Same idea as iSCSI, but taken down to the ATA level.
- CDP will emerge as an important feature on comprehensive data protection products instead of a separate managed product.
Here, CDP stands for Continuous Data Protection. While normal backups work like a point-and-shoot camera, taking a picture of the data once every midnight for example. CDP can record all the little changes like a video camera, with the option to rewind or fast-forward to a specific point in the day. IBM Tivoli CDP for Files, for example, is an excellent complement to IBM Tivoli Storage Manager.
The technology is not really new, as it has been implemented as "logs" or "journals" on databases like DB2 and Oracle, as well as business applications like SAP R/3.
The prediction here, however, relates to packaging. Will vendors "package" CDP into existing backup products, possibly as a separately priced feature, or will they leave it as a separate product that perhaps, like in IBM's case, already is well integrated.
- The VTL market growth will continue at a much reduced rate as backup products provide equivalent features directly to disk. Deduplication will extend the VTL market temporarily in 2007.
VTL here refers to Virtual Tape Library, such as IBM TS7700 or TS7510 Virtualization Engine. IBM introduced the first one in 1997, the IBM 3494 Virtual Tape Server, and we have remained number one in marketshare for virtual tape ever since. I find it amusing that people are now just looking at VTL technology to help with their Disk-to-Disk-to-Tape (D2D2T) efforts, when IBM Tivoli Storage Manager has already had the capability to backup to disk, then move to tape, since 1993.
As for deduplication, if you need the end-target box to deduplicate your backups, then perhaps you should investigatewhy you are doing this in the first place? People take full-volume backups, and keep to many copies of it, when a more sophisticated backup software like Tivoli Storage Manager can implement backup policies to avoid this with a progressive backup scheme. Or maybe you need to investigate why you store multiple copies of the same data on disk, perhaps NAS or a clustered file system like IBM General Parallel File System (GPFS) could provide you a single copy accessible to many servers instead.
The reason you don't see deduplication on the mainframe, is that DFSMS for z/OS already allows multiple servers to share a single instance of data, and has been doing so since the early 1980s. I often joke with clients at the Tucson Executive Briefing Center that you can run a business with a million data sets on the mainframe, but that there wereprobably a million files on just the laptops in the room, but few would attempt to run their business that way.
- Optical storage that looks, feels and acts like NAS and puts archive data online, will make dramatic inroads in 2007.
Marc says he's going out on a limb here, and that's good to make at least one risky prediction. IBM used to have anoptical library emulate disk, called the IBM 3995. Lack of interest and advancement in technology encouraged IBM to withdraw it. A small backlash ensued, so IBM now offers the IBM 3996 for the System p and System i clients that really, really want optical.
As for optical making data available "online", it takes about 20 seconds to load an optical cartridge, so I would consider this more "nearline" than online. Tape is still in the 40-60 second range to load and position to data, so optical is still at an advantage.
Optical eliminates the "hassles of tape"? Tape data is good for 20 years, and optical for 100 years, but nobody keeps drives around that long anyways. In general, our clients change drives every 6-8 years, and migrate the data from old to new. This is only a hassle if you didn't plan for this inevitable movement. IBM Tivoli Storage Manager, IBM System Storage Archive Manager, and the IBM System Storage DR550 all make this migration very simple and easy, and can do it with either optical or tape.
The Blue-ray vs. DVD debate will continue through 2007 in the consumer world. I don't see this being a major player in more conservative data centers where a big investment in the wrong choice could be costly, even if the price-per-TB is temporarily in-line with current tape technologies. IBM and others are investing a lot of Research and Development funding to continue the downward price curve for tape, and I'm not sure that optical can keep up that pace.
Well, that's my take. It is a sunny day here in China, and have more meetings to attend.

Well, I have left Japan, and while everyone else is enjoying the Super Bowl, I am now in Australia, at another conference.Today I had the pleasure to hear filmmakers talk about their successes, and how IBM helps the movie industry.
- Khoa Do
At one extreme was Khoa Do, independent filmmaker. After acting in movies asideMichael Caine and Billy Zane, he decided to become his own director. He started a project to help seven disadvantaged youths from a poor drug-ridden section of Sydney, by having them act in his first full-length film.Armed with only an IBM laptop and small budget, he made the film called "The Finished People" that had critical acclaim.
The film was a success, and many of the disadvantaged youths have gone on to act in other movies. In 2005, Khoa Do was named "Young Australian of the Year".
Thanks to IBM technology, filmmaking is now accessible to a wider number of aspiring wanna-be directors. It is no longer necessary to be part of a large film studio with a multi-million dollar budget to tell your story.
- Xavier Desdoigts
At the other extreme, was Xavier Desdoigts, director of technical operations at Animal Logic, the Computer Graphics (CG) arthouse that produced special effects of movies like "The Matrix", "House of Flying Dragons" and "World Trade Center". They started with producing digital effects for TV commercials, like this one forCarlton Draught Beer.
With the support of a large film studio and multi-million dollar budget, Animal Logic now boasts the 86th most powerful "Supercomputer" based on IBM BladeCenter technology, with over 4000 servers connected into a cluster, for making the movie "Happy Feet". The movie took four years to make, with over 500 people, of 27 different nationalities. It was the first CG movie made in Australia, and has been well-received by audiences worldwide.
Mr. Desdoigts gave out some interesting facts and figures about the movie:
- While visually stunning on the big screen, each frame is only 1.4 Megapixel, about the same resolution as most camera phones.
- In one scene, there are 427,086 penguins all appearing on frame.
- Mumble, the lovable lead character, is made up of over 6 million feathers.
- As many as 17 dancers were "motion-captured" to choreograph the tap-dancing and character interaction segments.
- Only one system admin was needed to manage this entire server farm. (IBM Systems Director technology makes this possible)
- The movie consumed 103 TB of disk space, backed up to 595 LTO tape cartridges.
- An estimated 17 million CPU-hours were needed for all the processing and rendering.
Rather than talking about technology for technology sake, these filmmakers showed how technology couldbe put to use, in a practical sense, to provide the world something of value.

Stephen Colbert, of The Colbert Report
, explains the name changes in recent mergers
of the Telecommunications industry. A discussion on "changing names" and how that impacts storage seems like a good way to wrap up the week's theme on naming conventions.
Name changes are sometimes painful, but often times done for a purpose, such as to promote a family. In the US, when a man and woman marries, the woman often changes her family name to match her husband, and the kids all adopt the father's family name. I say "often" because there are times where the woman keeps her name, or adds to it in a hyphenated way. ABC News reported that a Man Fights to Take Wife's Name in Marriage. KipEsquire, a lawyer, writes about it in his blogA stitch in haste.
IT industry changes the names of products that people knew as something else. Other times, they re-use an existing name, when really it is or should be different from the original. Last year, I took on the job of helping transition from our brand "TotalStorage" to the "System Storage" product line under the new "IBM Systems" brand. I help decide what stays the same name or what changes, when it should change, and how to announce that change.
On the disk side, IBM renamed Fibre Array Storage Technology, or FAStT, which was pronounced exactly like "fast", to DS4000 series. This was a big improvement, as people couldn't seem to spell it properly, with variations like "FastT". Nor could people pronounce it properly, saying "fast-tee" instead. The advantage of "DS" is that it is both easy to spell, and easy to pronounce. The DS4000 series continues to be "fast", providing excellent performance for its midrange price category.
IBM's Enterprise Storage Server (ESS) line went from model E10, to F20, to 750 and 800. When IBM came out with its replacement, the IBM TotalStorage DS8000, some people asked why it wasn't named the ESS 900, for example. The DS8000 is quite different internally, new hardware design and implementation, but is highly compatible with the ESS line, and shares much of the same functionality from microcode. Last year, it was replaced by the IBM System Storage DS8000 Turbo. Again, newer hardware, so it was easy to justify the new name change from "TotalStorage" to "System Storage".
Renaming a product risks losing its certifications and awards. For example, IBM spent a lot of time and money getting the OS/390 operating system certified as a "UNIX" platform. When it was renamed to z/OS, IBM had to do it all over again. Learning from this experience, IBM decided not to rename the SAN Volume Controllerto a new designation like "DS5750", as it enjoys the "number one" spot on both the SPC-1 and SPC-2 performance benchmarks, and is recognized as the leader in the disk storage virtualization marketplace. Renaming this product would mean losing that collateral.
IBM's "other disk systems" the N series posed another set of challenges. The current DS line already has entry-level (DS3000), midrange (DS4000) and enterprise-class (DS6000 and DS8000) products. The OEM agreement that IBM has with Network Appliance (NetApp) resulted in a new set of entry-level, midrange, and enterprise-class products. But these didn't fit nicely into the DS3000-to-DS8000 continuum. Instead, IBM decided to go with N series, using N3000 for entry-level, N5000 for midrange, and N7000 for enterprise-class. These are different than the numbers used by NetApp for their comparable, but not identical, offerings.
On the tape side, IBM decided to name the tape drives TS1000 and TS2000 range, tape libraries and automation with a TS3000 range, and tape virtualization to the TS7000 range. A lot of tape products already had 3000 numbering that had to change to fit this new scheme. This is why IBM's popular 3592 tape drive was renamed to the TS1120. The replacement to the 3494 Virtual Tape Server was named TS7700 Virtualization Engine.
Obviously, you can't change the names of products that are currently in the field, but what about existing software with minor updates? IBM decided to leave "TotalStorage Produtivity Center" under the "TotalStorage" brand until it has a significant version upgrade. Many people say "TPC" as a convenient acronym when referring to this product, but TPC is a registered trademark of the Professional Golfers Association (PGA) to refer to its "Tournament Players Club".
How can anyone confuse "managing storage" with "playing golf"? One activity is full of frustration that takes years or decades to master, involving the need to understand a variety of equipment and techniques to use each properly to accomplish your goals; and the other is an enjoyable activity, immediately productive in front of a single pane of glass managing all of your DAS, SAN and NAS storage, from reporting on your files and databases to managing storage networks and tape libraries.
Enjoy the weekend!

Continuing this week's theme of New Year's Resolutions for the data center, today we'll talk about one that people don't always think about on a personal level, that is to hone your tools and skills.
A long time ago, I used to be a regular speaker at the SHARE user group conference. One of the most attended sessions was Sam Golob presenting the latest CBT Tape set of tools. Over time, this large collection of "mainframe shareware" was handed out on 3480 tape cartridges, then on CDs, and finally made downloadable off the web.Sam's main point, which I remember to this day, was that everyone who has a job should figure out what tools they use, keep those tools functioning properly, and learn to use them well.
Later, I took some cooking classes at a culinary school. Among other things, we learned:
- A sharp knife is safer and easier to use than a dull one, resulting in fewer accidents
- Knowing what you are doing is the difference between food that is "simply awful" to that which is "awfully simple" to prepare.
- A well trained chef can prepare most meals with just a sharp knife and wooden spoon.
This last point hits close to home, as many people like me have too many tools that they do not use often enough to know how to use them well. Do I really need my strawberry corer, garlic press, or a tray designed for the storage and delivery of deviled eggs?
The same could be said about software tools. What tools do you use in your job? Do you feel you know how to take full advantage of their power and capabilities?If you develop software, do you know all the features for your debugging tools? If you develop advertising or marketing materials, do you know all the features of your photo or video editing software? If you manage storage in a data center, do you know all the tools for managing your storage area network (SAN), disk systems, tape libraries, and reporting tools to identify all of your files and databases across your entire IT environment?I would not be surprised if you could replace a whole mess of tools with just one, such as the IBM TotalStorage Productivity Center.
For me, I resolve to learn how to better use Lotus Notes e-mail client, and perhaps the new Office 2007.
