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.
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
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.
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.
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.
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]
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.
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.
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:
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.
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.
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.
I was in Raleigh this week, in business meetings, and had dinner last night at a Japanese Tepanyaki restaurant. The man next to me was dining alone, and said he worked for Cisco, a big company, "Had you heard of it?" he asked. Of course, I told him, I work for IBM, and IBM and Cisco have a strong working relationship, using each others products in both directions. He said he understood why they would use IBM, but why would IBM buy anything from them, and then he said, "Oh yes, your cafeteria".
At this point we realized he was talking about SYSCO, the food company, not Cisco, the storage networking technology partner. We both had a good laugh.
Which brings me to think of other "mis-heard" or "mis-interpreted" items that might have caught people off guard because they sounded similarly.
zFS versus ZFS
Some things are case-sensitive. Lower case zFS is the hierarchical file system for the z/OS mainframe environment, which was originally called "episode" file system that IBM acquired from TransArc. z/OS supports two file systems, HFS and zFS. Meanwhile, ZFS is one of the file systems available for Sun Solaris. Apple Mac OS is switching from its own HFS, different than the z/OS version, over the Sun's ZFS.
packs versus PACS
Older mainframers call disk volumes "packs". This started in the days where disks were "removable" and you can pack and unpack them into the drive unit.
PACS on the other hand refers to the "Picture Archive and Communication System" application environment used by hospitals and medical facilities to storage and share X-ray, Cardiology and Radiology images. Today, modern medical equipment are called "modalities" and directly connect to NAS storage via NFS or CIFS protocols. The images are immediately digitized and sent to disk, then tape, for long-term archive storage. IBM's Grid Medical Archive Solution (GMAS) is designed specifically for this environment.
rack versus RAC
Perhaps my favorite was when someone asked a high-level executive at a conference if their storage product supported Oracle RAC, and the response was that it supported anyone's rack, so long as it met the 19 inch standard. Everyone burst out laughing, and he probably had to be explained what was going on afterward.
Oracle RAC refers to Real Application Cluster, allowing multiple Oracle servers to work together as a system. A "rack" is just the powered shelf, typically 19" wide, and typically 25U or 42U tall, that allows modular servers, storage or network gear be placed together in a data center. A "U" is 1.75 inches, the thickness of a "two-by-four" piece of lumber. If you have ever used a 3.5 inch or 5.25 inch floppy diskette, then you already know the 2U and 3U sizes.
I am sure there are many other examples of similar sounding terms and phrases. If you have any to contribute, post a comment below!
Guy Kawasaki is hosting a Web Conference next week on The Art of Evangelism.By this he is referring to promoting products and services, rather than the traditionaldefinition: the preaching or promulgation of the gospel.
A few years ago, I myself had the official title of "Technical Evangelist" for the IBM System Storageproduct line. I never liked the title, and asked to use something else, but since I was part of ateam of "Technical Evangelists," I had to keep it. A lot of companies were using this as a title,I was told, and everyone knew that it was not a religious reference, but a marketing one.
Sometimes, words do not translate well into other countries or cultures. Four years ago, on theweek of September 11, 2003, I traveled to Kuwait, Qatar and UAE for a business trip to present thelatest on our storage products. On arrival in Kuwait, I had to fill out my "visa application" to enterthe country, and it asked for my "occupation/title" but there were not enough spaces to write "Technical Evangelist" so I just entered "Evangelist".
The two Kuwaitis behind the desk looked it up in their Arabic/English dictionary, discussed it, andweren't sure if they should shoot me, or take me to the back room to video tape my proper be-heading. Our official hostcame over to ask what was the delay, and they showed her the dictionary translation. She asked me,"Why would you put Evangelist as your title?" So, I gave her my business card, and told herthat my full title of Technical Evangelist did not fit in the space provided.
She explained to the two behind the desk that I had misunderstood the question, and misspelled theactual word intended was "Engineer". She showed them the agenda of the IBM Technical Conference I wasspeaking at, and the list of Oil and Construction companies that were attending. They looked upthe new title "Engineer", and agreed the translation was suitable for entry, and that these two words,Evangelist and Engineer, used enough similar letters they could understand how one might misspell one for the other.
Our limo took a small detour to the middle of the desert so that we could burn and bury the ashes of the remainder of my business cards, before arriving to the hotel. All of my powerpoint slides that listed my title were changed to "Technical Engineer". The events themselves went very well,as IT people are the same all over the world, and had no problem setting aside religious or politicaldifferences in an effort to learn more about technology.
When I got back to the United States, I shared my experience with my fellow team-mates, most of whom never leavethe country, and would never have thought this might happen. Management agreed to let us change our titles.That was good for me, as I had to order a new box of business cards anyways.
Last year, I became "Manager of Brand Marketing Strategy" of the IBM System Storage product line.Now on business trips I just write "Manager" on the Occupation/Title line. It fits in every form I have ever had to fill, and translates properly into every language.
Well, we had another successful event in Second Life today.
Unlike our April 26 launch of our System Storage products for IBM Business Partners only, this time we decided this time to make it as a "Meet the Storage Experts" Q&A Panel format, and open up registration to everyone. Thesubject matter experts sat at the front of the room on four stools. We had six rows of chairs arrangedsemi-circularly.
Shown above, from left to right, are the avatars of our four experts:
IBM System Storage N series, focusing on recent N3000 disk system announcements
Harold Pike (holding the microphone while speaking)
IBM System Storage DS3000 and DS4000 series, focusing on recent DS3000 disk system announcements
IBM System Storage TS series, focusing on recent TS2230, TS3400 and TS7700 tape system announcements
IBM storage networking, focusing on recent IBM SAN256B director blade announcements
While Eric was a veteran Second Lifer, having presented at our April event, the other three were trainedon how to raise their hand, speak into the microphone, sit on the stool, and so on. I want to thank allof our experts for putting in this effort!
The event was produced by Katrina H Smith. She did a great job, and made sure we were on top ofall the issues and tasks required to get the job done. Running a Second Life event is every bit ashard as running a real face-to-face event. We had several meetings to discuss venue details, placementof chairs, placement of product demos, audio/video recording, wall decorations, tee-shirt and coffee mug design, logistics, and so on.
I acted as moderator/emcee for the event. That is my back in the picture above. The process wassimple, modeled after the "Birds of a Feather" sessions at events like SHARE and the IBMStorage and Storage Networking Symposium. We threw out a list of topics the experts would cover,and people in the audience would "raise their left hand". I, as the moderator, would then walkover to each person, and hold out the microphone for them to ask the question. I would then repeat the question and ask the appropriate expert to provide an answer. We defined gestures onhow to "raise hand" and "put hand down" that we gave to each registered participant.
We had four dedicated "camera-avatars" in world to capture both video and screenshots.Our video editors are now working to edit "highlight videos" that we can use at future events, for training materials, and for our internal "BlueTube" online video system.
The room was filled with examples of each of our products, made into 3D objects that were dimensionallycorrect, and "textured" with photographs of the actual products. If you click on an object, you get a "notecard" that provided more information. Special thanks to Scott Bissmeyer for making all of theseobjects for us.
We made posters of each expert and placed them in all four corners of the room. On the bottom of each coffee mug was a picture of each of the experts, and if you walked under each of the posters, you were"dispensed" a coffee mug matching the expert shown in the poster.Participants could "Collect all Four!" When you bring the coffee mug up to takea sip, the picture on the bottom of the mug is exposed for all to see.And as a final give-away to the audience, we made a variety of event tee-shirts and polo-shirts.
At the end of the session, we asked everyone to click on the "Survey" kiosk near the exit door. We askedsix simple questions using SurveyMonkey.com that took only a fewminutes to process. We found asking questions immediately at the end of the event was the best way tocapture this feedback.
From a "Green" perspective, we had people registered from the following countries: US, India, Mexico,Australia, United Kingdom, Brazil, Germany, Argentina, Chile, China, Canada, and Venezuela. Second Lifeallows all these people who probably could not travel, or could not afford the time and expense to travel,to participate in a simulated face-to-face meeting without energy consumption of traditional travel methods.
More importantly, we got several leads for business. People often ask "Yes, but is there any businessassociated with this?" This time, there was, based on the answers to the questions, several avatars asked for a real sales call to follow-up on the products and offerings they were discussed.
With such a great success, we have already scheduled our next Second Life event, November 8. Mark your calendars! I'll postmore details on the registration process of the November event when available.
Today I spoke at the IBM Think Green Roadshow in Phoenix, Arizona. This is justone of a 15-city tour to help make people aware of Green data center issues.Here is the schedule forthe remaining cities. Contact your local IBM rep for details.
Victor Ferreira was our moderator and host. He is the site level executive for the2000 IBM employees in the Phoenix area, and manages the Public Sector for our Westernregion.
The first speaker was Dave McCoy, IBM principal in our Data Center services group.He explained IBM's Project Big Green and the Energy Efficiency Initiative, and wentinto details on how IBM can act as general contractor to design, plan and build theideal Green Data Center for you. IBM can also retrofit existing buildings, with new technologies like stored cooling, optimized airflow assessments, and modulardata center floorspace. While not related to energy, but still important to ourenvironment was IBM Asset Recovery Services, where IBM can take all those old PCmonitors, keyboards and other outdated equipment and refurbish or melt down to recapture useful metals and plastics, and disposing the rest in an environmentally-friendly,non-toxic manner.
I was the second speaker, covering "How to get it done". While Dave covered the issuesand technologies available, I explained how to put it all into practice. This includesIT systems assessments, health audits, and thermal profiling. Using server and storagevirtualization, you can increase resource utilization and reduce energy waste. IBM's CoolBlueproduct line, which includes the IBM PowerExecutive software to monitor your IT environment, and the "Rear Door Heat Exchanger" that uses chilled water to remove asmuch as 60% of the heat coming out of the back of a server rack, greatly reducing hot-spotson the data center floor, and allowing you to run the entire room at warmer, less-expensivetemperatures.
On the server side, I covered IBM's System z mainframe and the BladeCenter as examples of how innovative technologies can be used to run more applications with less energy. The newSystem p570 based on the energy-intelligent POWER6 processor has twice the performance for the same amountof power as its POWER5 predecessor. On thestorage side, I explained how Information Lifecycle Management (ILM), storage virtualization,and the use of a blended disk and tape environment can greatly reduce energy costs.
Reps from our many technology partners Eaton, APC, Schneider Electric, Liebert, and Anixter werethere to support this event.
The session ended with a Q&A Panel, with Dave McCoy, myself, and Greg Briner from IBM GlobalFinancing. IBM is able to offer creative "project financing" that can often times match theactual monthly savings, resulting in net zero cost to your operational budget, with payback periods as little as 2.5 years.

To get beyond the simple statistics of vendor popularity, we looked at the number and combinations of vendors with which enterprises work. Many were customers of one or two storage providers, but the rest were customers of up to six storage providers. More than one-third were customers of systems vendors only, bypassing storage specialists.
Comparisons between solutions vendors and storage component vendors are not new. One could argue that this can be compared to supermarkets and specialty shops.
Supermarkets offer everything you need to prepare a meal. You can buy your meat, bread, cheese,and extras all with one-stop shopping. In a sense, IBM, HP, Sun and Dell are offering this to clients who prefer this approach. Not surprisingly, the two leaders in overall storage hardware,IBM and HP, are also the two best to offer a complete set of software, services, servers and storage.
IBM and HP are also the leaders in tape.While Forrester reports that many large enterprises in North America prefer to buy diskfrom storage specialists, others have found that customers prefer to buy their tape from solution providers. Recently, Byte and Switch reports thatLTO Hits New Milestones,where the LTO consortium (IBM, HP, and Quantum) have collectively shipped over 2 million LTO tape drives, and over 80 million LTO tape cartridges. Perhaps this is because tape is part of an overallbackup, archive or space management solution, and customers trust a solution vendor overa storage specialist.
Where possible, IBM brings synergy between its servers and storage. For example, we justannounced the IBM BladeCenter Boot Disk System, a 2U high unit that supports up to 28 blade servers, ideal for applications running under Windows or Linux, and helping to reduce the energy consumption for thoseinterested in a "Green" data center.
Some people prefer buying their meat at the slaughterhouse, bread at the French pastry shop, andso on. Storage specialists focus on just storage, leaving the rest of the solution, like servers,to be purchased separately from someone else. Storage vendors like NetApp, EMC, HDS and othersoffer storage components to customers that like to do their own "system integration", or to thosethat are large enough to hire their own "systems integrator".
Storage specialists recognize that not everybody is a "specialty shop" shopper.HDS has done well selling their disk through solution vendorslike HP and Sun. EMC sells its gear through solution vendor Dell.
Interestingly, I have met clients who prefer to buy IBM System Storage N series from IBM, becauseIBM is a solution vendor, and others that prefer to buy comparable NetApp equipment directly fromNetApp, because they are a storage component vendor.
I mostly buy my groceries at a supermarket, buthave, on occasion, bought something from the local butcher, baker or candlestick maker. And if you are ever in Tucson, you might be able to find Mexican tamalessold by a complete stranger standing outside of a Walgreens pharmacy, the ultimate extreme of specialization. You can get a dozen tamales for tenbucks, and in my experience they are usually quite good. Theoretically, if you get sick, or they don't taste right, you have no recourse, and will probably never see that stranger again to complain to.(And no, before I get flamed, I am not implying any major vendor mentioned above is like this tamale vendor)
Of course, nothing is starkly black and white, and comparisons like this are just to help provide context and perspective,but if you are looking to have a complete IT solutionthat works, from software and servers to storage and financing, come to the vendor you can trust, IBM.
A few weeks ago, my Tivo(R) digital video recorder (DVR) died. All of my digital clocks in my house were flashing 12:00 so I suspect it wasa power strike while I was at the office. The only other item to die was the surge protector,and so it did what it was supposed to do, give up its own life to protect the rest of myequipment. Although somehow, it did not protect my Tivo.
I opened a problem ticket with Sony, and they sent me instructions on how to send itover to another state to get it repaired.Amusingly, the instructions included "Please make a backup of the drive contents beforesending the unit in for repair." Excuse me? How am I supposed to do that, exactly?
My model has only a single 80GB drive, and so my friend and I removed the drive and attachedit to one of our other systems to see if anything was salvageable. It failed every diagnostictest. There was just not enough to read to be usable elsewhere.
This is typical of many home systems. They are not designed for robust usage, high availability, nor any form of backup/recovery process. Some of the newer models havetwo drives in a RAID-1 mode configuration, but most have many single points of failure.
And certainly, it is not mission critical data. Life goes on without the last few episodesof Jack Bauer on "24", or the various Food Network shows that I recorded for items I planto bake some day. For the past few weeks, I have spent more time listening to the radioand reading books. Somehow, even though my television runs fine without my Tivo, watchingTV in "real time" just isn't the same.
I suspect that if you gave someone a method to do the backup, most would not bother to useit. People are now relying more and more heavily on their home-basedinformation storage systems, digital music, video and cherished photographs. Perhaps experiencing a "loss" will help them appreciate backup/recovery systems so much more than they do today.
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.
A new storage infrastructure with the capacity to grow with the University of Pittsburgh as needed
Improved system reliability with reduced downtime, and availability 24/7/365
A significantly more manageable storage solution that could lower costs and provide better system efficiency through virtualization
As a result, IBM shipped its 25,000th high-end disk storage system, in this case two IBM System Storage DS8300 models, along with storage virtualization, and other related hardware, software and services, to provide a complete end-to-end solution.
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"
ESG Analyst, Tony Asaro, talks about the many small storage startups having aBillion Dollar Impact on the storage system industry. Tony has counted over50 storage system vendors that are now in the marketplace. Is it really that many?Most of the time, the media only focus on the top seven major players, but I agree that big players like IBM should take trends about small startups like this seriously.
EMC Blogger Chuck Hollis suggests that this trend might be the start of a squeeze play, where top players and new upstarts squeeze out the middle playerslike Sun and HDS, in his postDesperate Times In Storage Land?
(His statement that IDC and Gartner have listed EMC as number one in "almost all"market segments is perhaps a bit misleading. IBM is number one in overall storage hardware, as wellas leading in tape drives, tape libraries, tape virtualization, and for that matter,disk virtualization. I don't know if IDC or Gartner count EMC Disk Library in the "tape virtualization" category, or if either analyst distinguishes between "cache-based" versus "switch-based" disk virtualization as separate categories.Perhaps Chuck should have qualified this to say "almost all of themarket segments that EMC does business in," which of course is better than the othervendors in the middle.)
Often, when looking at disk storage it is easy to focus on comparisons to other disk storage, but disruptive technologies cross boundaries. Already we have seen Flash Memory drives on the IBM BladeCenter, replacing traditional disk drives internal to each blade server. They are smaller than regular disk drives, but big enough to hold the operating system to boot from.
The New York Times has an article by John Markoff, Redefining the Architecture of Memory that talks about IBM's research on "Racetrack Memory".The article is a good read, but here are some interesting excerpts:
Now, if an idea that Stuart S. P. Parkin is kicking around in an I.B.M. lab here is on the money, electronic devices could hold 10 to 100 times the data in the same amount of space.
Currently the flash storage chip business is exploding. Used as storage in digital cameras, cellphones and PCs, the commercially available flash drives with multiple memory chips store up to 64 gigabytes of data.
However, flash memory has an Achilles’ heel. Although it can read data quickly, it is very slow at storing it. That has led the industry on a frantic hunt for alternative storage technologies that might unseat flash.
Mr. Parkin’s new approach, referred to as “racetrack memory,” could outpace both solid-state flash memory chips as well as computer hard disks, making it a technology that could transform not only the storage business but the entire computing industry.
But ultimately, the technology may have even more dramatic implications than just smaller music players or wristwatch TVs, said Mark Dean, vice president for systems at I.B.M. Research.“Something along these lines will be very disruptive,” he said. “It will not only change the way we look at storage, but it could change the way we look at processing information. We’re moving into a world that is more data-centric than computing-centric.”
This technology has the potential to break some of the physical limitations that are currently worrying disk drive designers. I look forward to see how this plays out.
Registration for the "Meet the Storage Experts" event in Second Life will close this week fornext week's September 20 event. All IBMers, clients and IBM Business Partners are welcome to attend. We will focus this time on DS3000 and N series disk systems, tape systems,and IBM storage networking gear.
If you miss this one, we plan to have another one in November!
Array-based replication does have drawbacks; all externalised storage becomes dependent on the virtualising array. This makes replacement potentially complex. To date, HDS have not provided tools to seamlessly migrate away from one USP to another (as far as I am aware). In addition, there's the problem of "all your eggs in one basket"; any issue with the array (e.g. physical intervention like fire, loss of power, microcode bug etc) could result in loss of access to all of your data. Consider the upgrade scenario of moving to a higher level of code; if all data was virtualised through one array, you would want to be darn sure that both the upgrade process and the new code are going to work seamlessly...
The final option is to use fabric-based virtualisation and at the moment this means Invista and SVC. SVC is an interesting one as it isn't an array and it isn't a fabric switch, but it does effectively provide switching capabilities. Although I think SVC is a good product, there are inevitably going to be some drawbacks, most notably those similar issues to array-based virtualisation (Barry/Tony, feel free to correct me if SVC has a non-disruptive replacement path).
I would argue that the IBM System Storage SAN Volume Controller (SVC) is more like the HDS USP, and less like the Invista. Both SVC and USP provide a common look and feel to the application server, both provide additional cache to external disk, both are able to provide a consistent set of copy services.
IBM designed the SVC so that upgrades can occur non-disruptively. You can replace the hardware nodes, one node at a time, while the SVC system is up and running, without disruption to reading and writing data on virtual disk. You can upgrade the software, one node at a time, while the SVC system is up and running, without disruption to reading and writing data on virtual disk. You can upgrade the firmware on the managed disk arrays behind the SVC, again, without disruption to reading and writing data on virtual disk.
More importantly, SVC has the ultimate "un-do" feature. It is called "image mode". If for any reason you want to take a virtual disk out of SVC management, you migrate over to an "image mode" LUN, and then disconnect it from SVC. The "image mode" LUN can then be used directly, with all the file system data in tact.
I define "virtualization" as technology that makes one set of resources look and feel like a different set of resources with more desirable characteristics. For SVC, the more desirable characteristics include choice of multi-pathing driver, consistent copy services, improved performance, etc. For EMC Invista, the question is "more desirable for whom?" EMC Invista seems more designed to meet EMC's needs, not its customers. EMC profits greatly from its EMC PowerPath multi-pathing driver, and from its SRDF copy services, so it appears to have designed a virtualization offering that:
Continuesthe use of EMC Powerpath as a multi-pathing driver. SVC supports driversthat are provided at no charge to the customer, as well as those built-in to each operating system like MPIO.
and, continuesthe use of Array-based copy services like SRDF of the underlying disk. SVC providesconsistent copy services regardless of storage vendor being managed.
A post from Dan over at Architectures of Control explains the anti-social nature of public benches. City planners, in an effort to discourage homeless people from sleeping on benches in parks or sidewalks, design benches that are so uncomfortableto use, that nobody uses them. These included benches made of metal that are too hot or too cold during certainmonths, benches slanted at an angle that dump you on the ground if you lay down, or benches that have dividers sothat you must be in an upright seated position to use.
This is not a disparagement of split-path switch-based designs. Rather, EMC's specific implementation appears to be designed for it to continuevendor lock-in for its multi-pathing driver, continuevendor lock-in for its copy services when used with EMC disk, and only provide slightly improved data migration capability for heterogeneous storage environments. Other switch-based solutions, such as those from Incipient or StoreAge, had different goals in mind.
Sadly, my IBM colleague BarryW and I have probably spent more words discussing Invista than all eleven EMC bloggers combined this year. While everyone in the industry is impressed how often EMC can sell "me, too" products with an incredibly large marketing budget, EMC appears not to have set aside funds for the Invista.
If a customer could design the ideal "storage virtualization" solution that would provide them the characteristics they desire the most from storage resources, it would not be anything like an Invista. While there are pros and cons between IBM's SVC and HDS's TagmaStore offerings, the reason both IBM and HDS are the market leaders in storage virtualization is because both companies are trying to provide value to the customer, just in different ways, and with different implementations.
When new technologies are introduced to the marketplace, it is normal for customers to be skeptical.
My sister is a mechanical engineer, so when she needs to configure a part or component, she candesign it on the computer, and then use a "Rapid Prototyping Machine"that acts like a 3D printer, to generate a plastic part that matches the specifications. Some machinesdo this by taking a hunk of plastic and cutting it down to the appropriate shape, and others use glue andpowder to assemble the piece.
But not everything is that simple. Harry Beckwith deals with the issue of selling services and software featuresin his book "Selling the Invisible". How do you sell a service before it is performed? How do you sell a softwarefeature based on new technology that the customer is not familiar with?
Our good friends over at NetApp, our technology partners for the IBM System Storage N series, developed a"storage savings estimator" tool that can provide good insight into the benefits of Advanced Single InstanceStorage (A-SIS) deduplication feature.
I decided to run the tool to analyze my own IBM Thinkpad C: drive (Windows operating system and programs) and D: drive ("My Documents" folder containing all my data files) to see how much storage savings thetool would estimate. Here are my results:
WINXP-C-07G (C: drive)Total Number of Directories: 1272Total Number of Files: 56265Total Number of Symbolic Links: 0Total Number of Hard Links: 41996Total Number of 4k Blocks: 2395884Total Number of 512b Blocks: 18944730Total Number of Blocks: 2395884Total Number of Hole Blocks: 290258Total Number of Unique Blocks: 1611792Percentage of Space Savings: 20.61Scan Start Time: Wed Sep 5 14:37:06 2007Scan End Time: Wed Sep 5 14:53:51 2007
WINXP-D-07H (D: drive)Total Number of Directories: 507Total Number of Files: 7242Total Number of Symbolic Links: 0Total Number of Hard Links: 11744Total Number of 4k Blocks: 3954712Total Number of 512b Blocks: 31610595Total Number of Blocks: 3954712Total Number of Hole Blocks: 3204Total Number of Unique Blocks: 3524605Percentage of Space Savings: 10.79Scan Start Time: Wed Sep 5 14:21:16 2007Scan End Time: Wed Sep 5 14:34:30 2007
I am impressed with the results, and have a better understanding of the way A-SIS works. A-SIS looks at every4kB block of data, and creates a "fingerprint", a type of hash code of the contents. If two blocks have different "fingerprints", then the contents are known to be different. If two blocks have the same fingerprint, it is mathematically possible for them to be unique in content, so A-SIS schedules a byte-for-byte comparison to be sure they are indeed the same. This might happen hours after the block is initially written to disk, but is a much safer implementation, and does not slow down the applications writing data.
(In an effort to provide support "real time" as data was being written, earlier versions of deduplication
had to either assume that a hash collision was a match, or take time to perform the byte-for-byte comparisonrequired during the write process. Doing this byte-for-byte comparison when the device is the busiest doingwrite activities causes excessive undesirable load on the CPU.)
The estimator tool runs on any x86-based Laptop, personal computer or server, and can scan direct-attached, SAN-attached, or NAS-attached file systems. If you are a customer shopping around for deduplication, ask your IBM pre-sales technical support, storage sales rep, or IBM Business Partner to analyze your data. Tools like this can help make a simple cost-benefit analysis: the cost of licensing the A-SIS software feature versus the amount of storage savings.
I can't believe I have been blogging for a year now!
I have Jennifer Jones from IBM to thank for getting this started. She was my predecessor in the job I have now, and she was moving on to bigger and better things, and during the transition for me to take over, she suggested that we start a blog, podcast, or similar. While there are many blogs and podcasts inside the firewall of IBM, I wanted something to be accessible to all of our IBM sales team, IBM Business Partners, existing and prospective clients, and to enable comments, to enable two-waycommunication. Podcasts are very one-way, so we chose a blog instead.Getting it set up took a while, convincing our own management that this was worthwhile, and dealing with our legal department on the IBM blogging guidelines of what we can and cannot write about, we finally got it going last year, launching September 1, just in time for our 50 years of disk systems innovation campaign.
It has been a wild ride, a great learning experience, and has proven quite fulfilling for job satisfaction. Here are some observations and lessons I have learned along the way.
Roller is the open source blog server that drives Sun Microsystem's blogs.sun.com employee blogging site, IBM DeveloperWorks blogs that this blog exists on, thousands of internal blogs at IBM Blog Central, the JRoller Java community site, and hundreds of others world-wide.Whereas there might be fancier blog systems elsewhere that I could have chosen, hosting my blog with IBM Developerworksseemed like a good choice. I can access from any web-browser capable machine, and enter my blog posts in nativeHTML, that I develop in the tool itself, or offline with a standard basic text editor like Microsoft Notepad that I can then cut-and-paste back in.
One lesson I learned the hard way was that Roller generates the Permalink URL for each blog post based on the first five words of the title. For that reason, it is important to chose an appropriate and unique title, avoiding the use of punctuation, quotation marks, or pharmaceutical "enhancement products" that might get rejected by SPAM filters.Once chosen, you can't change the title afterwards as it won't match the Permalink anymore.My blog post "Aperi is (enhancement product) for SMI-S" caused no end of grief to our Press Release team.
Writing blog posts in native HTML is not as hard as it sounds. I am limited to hosting a maximum of 24MB of files, and they can only be jpg, jpeg, gif, png, mp3, pdf or ppt format.So, wherever possible, I point to other websites for content.For those new to blogging, I recommendThe Barebones Guide to HTML.
Roller also generates for me a spreadsheet of all my page views for the week. Tracking blog traffic closely is as crazyas checking your company's stock price every day. These "web-stat" e-mails get filed directly into my Bacn folder on Lotus Notes.
In my earlyadvice to bloggers, I mentioned my choice of Bloglines as my RSS feed reader. When I subscribe to a new blog, I specify Full entries, not Partial,which allows me to scan it quickly, but filters out many of the non-text content like videos. It also allowed meto see what my own blog posts looked like from within a reader, so that I can write them appropriately.
I find if valuable to read other blogs, including those written by employees of our toughest competitors. Evenif you don't blog yourself, following blogs can be extremely valuable. Be careful what you leave as comments onother blogs, they may come back to haunt you later.
Currently, I track 55 blogs, some about storage,marketing, Web 2.0 issues, Second Life, Linux, or other areas of interest. I prefer blogs that make only 1-5 postsper week, so blogs like LifeHacker and LifeRemix are off my Bloglines list, but are excellent resourceswhen I am searching for something specific. If you think 55 is a lot of blogs, consider Timothy Ferriss' post onHow RobertScoble reads 622 RSS feeds each morning.
I have quite an international readership, so I have to be careful using American idioms and pop cultural references.For example, in my blog post IBM acquires Softek, I mentioned "shotgun weddings" and had various responses asking what exactly did that mean,all from readers outside the USA. I've learned that sometimes you need to link them to an American Slang dictionary,or Wikipedia encyclopedia entry to explain these terms and phrases.
Technoraticurrently tracks over 100 million blogs and over 250 million pieces of tagged social media. Getting my blogtracked had some issues. You have to join, thenpost a "claim"on your own blog. My mistake was having a case-sensitive URL with a mix of upper and lower case letters, but Technorati prefers all lower case. IBM worked with Technorati to get this resolved.
Del.icio.us is a social bookmarking website -- the primary use is to store your bookmarks online, which allows you to access the same bookmarks from any computer and add bookmarks from anywhere, too. On del.icio.us, you can use tags to organize and remember your bookmarks, which is a much more flexible system than folders.
I use Firefox, Safari, Dillo and Internet Explorer web browsers, so it is nice that I have access to allmy bookmarks in the same consistent manner. When I see content on a website that I might like to reference laterin a blog, I tag it with del.icio.us so that I can get to it later.
Fellow GTD-ers will quickly recognize this acronym, but for the rest of you, it refers to David Allen's book "Getting Things Done®".This is a great book! I learned about it reading other people's blogs, and found it incrediblyuseful helping me organize my time.There are various online tools available to help employ this method. I use Lotus Connections Activitiesfor group projects with co-workers at IBM, and BackPack for projects withmy friends outside of work.
The success of YouTube encouraged IBM to launch IBM TV, a portal for IBM's video and multimedia assets and make it easier for IBM employees, customers, partners and prospects to access and view IBM multimedia. The plan is to have eight anchor episodes per year, professionally hosted by TV personality, Joe Washington, and point to related offers and other resources for viewers to learn more.
Blogging also introduced me to Second Life. I asked around if anyone else within IBM was using Second Life, anddiscovered quite a few. I got invited to join our internal Eightbar group, and participated in various events, including an IBM Holidayparty that I discussed in my blog post"Building a Snowman in Second Life".
In April, we had a launch of our newest products in Second Life, and we plan to have two more Second Life events,September 20 and another in November, staged as "Meet the Experts" question and answer panels.
I wrap up with Facebook. Actually, whereas most of my Web 2.0 efforts have been work-related, I have quite a few friends and family who follow my blog. Several were inspired to start their own blogs, such asPassages from Pamand Barry Whyte on Storage Virtualization. Bridging the gap is Facebook, something I can use to keep tabs on my friends, as well as my storage industry-related contacts.
Wow, that's quite a lot in one year. Well, I am done with my meetings down here in Sao Paulo, Brazil. My colleauges and I are returning tonight to enjoy the long Labor Day weekend.
