When times are tough, people revert back to their "default programming", and companies search for their"core strengths".The Redwoods Group calls this the[Native Language Theory
]. Here'san excerpt:
A young carpenter immigrates to the United States from Italy, unable to speak a word of English. Upon arrival, he moves into a small apartment by himself and begins looking for a job in construction. With some luck and a lot of hard work, he quickly lands a job at a local construction site. Over the coming weeks he learns how to say “hello” and “goodbye” to his English-only coworkers. As time goes on, he is able to learn more complex phrases and commands and is now able to begin taking on jobs that better match his level of expertise.
Several years after the carpenter moved to the US, he now speaks fluent English and has started a family with an American woman and now speaks only English on the job site and at home. One afternoon, while hammering at the framing of a new home, the carpenter strikes his thumb. In what language does he curse?Italian, of course.
We believe that this story illustrates the nature of reacting to difficult, stressful, and, yes, painful situations by reverting to what you know best. This is the reason that coaches ask their players to make certain actions “instinctual” – simply, when times get tough, we do what we fall back on our native language.
Last September, in my post[Supermarketsand Specialty Shops] I mentioned how Forrester Research identified two kinds of IT vendors selling storage. On one side were the"information infrastructure" companies (IBM, HP, Sun, and Dell) that focus on providing one-stop shopping for clients that want all parts of an IT solution, including servers, storage, software and services. These I compared to "supermarkets".
On the other side were the storage component vendors (EMC, HDS, NetApp, and many others) that focus on specificstorage components. These I compared to "specialty shops", like butchers, bakers and candlestick makers.These often appeal to customers with big enough IT staffs with the skills to do their own system integration.The key difference seems to be that the supermarkets are client-focused, and the specialty shops are technology-focused, and different people prefer to do business with one side or another.This came in handy last November to explain Dell's acquisition of EqualLogic and discuss[IBMEntry-Level iSCSI offerings].
Some recent news seems to fit this model, in relation to the Native Language Theory.
Several argued that EMC was in the process of shifting sides, from disk specialty shop over to an everything-but-servers supermarket. Certainly many of its acquisitions in software, services, and VMwarewould support the notion that perhaps they are going through an identity crisis.The immediate beneficiary was HDS, the #2 disk specialty shop, that passedup EMC with innovative features in its USP-V disk system.
However, times are tough, especially in the U.S. economy that many storage vendors are focused on. EMCappears to have found its native language, going back to its roots of solid state storage systems thatthey started with back in 1979. This week EMC announced [Symmetrix DMX-4 support of Flash drives].Several bloggers review the technology involved:
Overall smart move for EMC to go back to its technology-focused disk specialty shop mode and go head-to-head against the HDS threat. With Web 2.0 workloads moving off these monolithic solutions and onto [clustered storage more appropriate for "cloud computing"], large enterprise-class disk systems like theIBM System Storage DS8000 and EMC DMX-4 can shift focus on what they do best: online transaction processing (OLTP) and large databases. However,I noticed the EMC press release mentions EMC as an "information infrastructure" company, so perhaps they stillhaven't resolved their identity crisis.
(For the record, IBM shipped [Flash drive-based storage last year], and announced [larger drive models] this week. As we have learned from last year, terms like "First" or "Leader" in corporate press releases should not always be taken literally.)
- Sun Microsystems
After Sun acquired StorageTek specialty shop, they too had a bit of an identity crisis.Fortunately, they realized their core strengths were on the "supermarket" side,moved storage in with servers in their latest restructuring, changed their NYSE symbol from SUNW to JAVA, and reset their focus on providing end-to-end solutions like IBM. For example, fellow blogger Taylor Allis from Sun mentions their latest in "clustered storage" in his post[IBM Buys XIV - Good Move].
Last August, in my post [Fundamental Changes for Green Data Centers], I mentioned that IBM consolidated 3900 rack-optimized servers onto 33 mainframes,and that this was part of our announcement that[since 1997, IBM has consolidated its strategic worldwide data centers from 155 to seven].I noticed in Nick Carr's Rough Type blog post[The Network is the Data Center] thatHP and Sun have followed suit:
In an ironic twist, some of today's leading manufacturers of server computers are also among the companies moving most aggressively to reduce their need for servers and other hardware components. Hewlett-Packard, for instance, is in the midst of a project to slash the number of data centers it operates from 85 to 6 and to cut the number of servers it uses by 30 percent. Now, Sun Microsystems is upping the stakes. Brian Cinque, the data center architect in Sun's IT department, says the company's goal is to close down all its internal data centers by 2015. "Did I just say 0 data centers?" he writes on his blog."Yes! Our goal is to reduce our entire data center presence by 2015."
While Nick feels this is ironic for Sun, known for UNIX servers based on their SPARC chip technology, I don't. Sun has shifted from being technology-focused to being client-focused.This is where the marketplace is going, and the supermarket vendors, being client-focused, are best positioned to adapt to this new world. In a sense, Sun found its roots. Nick summarizes this as:"The network, to spin the old Sun slogan, becomes the data center."
So, each move seems to strengthen their respective identities back to their origins, or at least help them communicate that to the market.

So here we are in January, named after the two-faced Roman god Janus, who in their mythology was the god of gates and doors, and beginnings and endings.
-- Roger von Oech[Our "Janus-Like" Powers]
Well, it's 2008, which could mark the end to RAID5 and mark the beginnings of a new disk storagearchitecture. IBM starts the year with exciting news, acquiring new disk technology from a smallstart-up called XIV, led by former-EMCer Moshe Yanai. Moshe was ousted publicly in 2001 from hisposition as EMC's VP of engineering, and formed his own company. It didn't take long for EMC bloggersto poke fun at this already. Mark Twomey, in his StorageZilla blog, had mentioned XIV before back in August,[XIV], and again todayin [IBM Buys XIV].
The following is an excerpt from the [IBM Press Release]:
To address the new requirements associated with next generation digital content, IBM chose XIV and its NEXTRA™ architecture for its ability to scale dynamically, heal itself in the event of failure, and self-tune for optimum performance, all while eliminating the significant management burden typically associated with rapid growth environments. The architecture also is designed to automatically optimize resource utilization of all the components within the system, which can allow for easier management and configuration and improved performance and data availability.
"We are pleased to become a significant part of the IBM family, allowing for our unique storage architecture, our engineers and our storage industry experience to be part of IBM's overall storage business," said Moshe Yanai, chairman, XIV. "We believe the level of technological innovation achieved by our development team is unparalleled in the storage industry. Combining our storage architectural advancements with IBM's world-wide research, sales, service, manufacturing, and distribution capabilities will provide us with the ability to have these technologies tackle the emerging Web 2.0 technology needs and reach every corner of the world."
The NEXTRA architecture has been in production for more than two years, with more than four petabytes of capacity being used by customers today.
Current disk arrays were designed for online transaction processing (OLTP) databases. The focus was onusing fastest most expensive 10K and 15K RPM Fibre Channel drives, with clever caching algorithmsfor quick small updates of large relational databases. However, the world is changing, and peoplenow are looking for storage designed for digital media, archives, and other Web 2.0 applications.
One problem that NEXTRA architecture addresses is RAID rebuild. In a standard RAID5 6+P+S configuration of 146GB 10K RPM drives, the loss of one disk drive module (DDM) was recovered by reconstructing the data from parity of the other drives onto the spare drive. The process took46 minutes or longer, depending on how busy the system was doing other things. During this time,if a second drive in the same rank fails, all 876GB of data are lost. Double-drive failures are rare,but unpleasant when they happen, and hopefully you have a backup on tape to recover the data from.Moving to slower, less expensive SATA drives made this situation worse. The drives have highercapacity, but run at slower speeds. When a SATA drive fails in a RAID5 array, it could take severalhours to rebuild, and that is more time exposure for a second drive failure. A rebuild for a 750GBSATA drive would take five hours or more,with 4.5 TB of data at risk during the process if a second drive failure occurs.
The Nextra architecture doesn't use traditional RAID ranks or spare DDMs. Instead, data is carved up into 1MBobjects, and each object is stored on two physically-separate drives. In the event of a DDM loss, allthe data is readable from the second copies that are spread across hundreds of drives. New copies aremade on the empty disk space of the remaining system. This process can be done for a lost 750GB drive in under20 minutes. A double-drive failure would only lose those few objects that were on both drives, so perhaps1 to 2 percent of the total data stored on that logical volume.
Losing 1 to 2 percent of data might be devastating to a large relational database, as this could impactthe entire access to the internal structure. However, this box was designed for unstructuredcontent, like medical images, music, videos, Web pages, and other discrete files. In the event of a double-drivefailure, individual files would be recovered, such as with IBM Tivoli Storage Manager backup software.
IBM will continue to offer high-speed disk arrays like the IBM System Storage DS8000 and DS4800 for OLTP applications, and offer NEXTRA for this new surge in digital content of unstructured data. Recognizing this trend, diskdrive module manufacturers will phase out 10K RPM drives, and focus on 15K RPM for OLTP, and low-speedSATA for everything else.
Update: This blog post was focused on the version of XIV box available as of January 2008 that was built by XIV prior to the IBM acquisition. IBM has since made a major revision, made available August 2008 thataddresses a variety of workloads, including database, OLTP, email, as well as digital content and unstructuredfiles. Contact your IBM or IBM Business Partner for the latest details!
Bottom line, IBM continues to celebrate the new year, while the EMC folks in Hopkington, MA will continue to nurse their hangovers. Now that's a good way to start the new year!

Today, IBM announced a software/server/storage combo that out-performed both HP and Sun. Here is an excerpt from the[IBM Press Release
IBM today announced that its recently introduced E7100 Balanced Warehouse(TM), consisting of the IBM POWER6(TM) processor-based System p(TM) 570 server, the IBM System Storage(TM) DS4800 and DB2(R) Warehouse 9.5, is already lapping the field in performance. The new data warehousing solution is now ranked number one in both performance and in price/performance in the TPC-H business:
- 2 x speed-up over HP system with Oracle 10g and equal number of cores;
- 3.17 x speed up over Sun with Oracle 10g and 38 percent price advantage;
- A new world record by loading 10 terabytes (TB) data at six TB per hour (TB/hr).
"These latest benchmark results further prove IBM's strength and leadership in the business intelligence arena," said Scott Handy, vice president of marketing and strategy, IBM Power Systems. "The E7100 Balanced Warehouse is a complete data warehousing solution comprised of pre-tested, scalable and fully integrated system and storage components, designed to get customers up and running quickly to get to the real benefit of unprecedented business insight and intellect."
Those not familiar with the [IBM Balanced Warehouse], it is the productized version of DB2's ["Balanced Configuration Unit" or BCU] reference configuration. The IBM Balanced Warehouse presents a pre-tested, pre-configured solution for Business Intelligence (BI) applications. These are in the form of "building blocks" thatcan be combined to get to the size you need, with incremental growth as your business expands. Each building block expertly matches the CPU processor and RAM memory of the server, with the appropriate I/O bus, cabling, and capacity of the disk system, resulting in optimal performance.
IBM DB2 software is designed to allow you to combine multiple building blocks into a single system image. This greatly simplifies your data warehouse deployment, and can help ensure success. For example, for a 50TB deployment, you can take a base 2TB building block, add 24 more, each with 2TB of disk capacity, and have a completely balanced environment. IBM clients have built systems over 300TB in this manner with these building blocks.
The IBM Balanced Warehouse is offered in several configurations:
The [C-class models] are designed for SMB customers, employing an IBM System x server with internal or direct attached EXP3000 disk.
The [D-class models] are the next step up, offering department-level data marts and data warehouse for larger deployments, employing an IBM System x server with EXP3000 or System Storage DS3400 entry level disk.
The [E-class models] represent our top-of-the line configurations for our largest enterprise deployments. The [E6000] run Linux on an IBM System x server with System Storage DS48000 disk. The [E7000] run AIX on an IBM System p575 server with DS4800 disk. The new [E7100] mentioned above runsAIX on a POWER6-based IBM System p570 with DS4800 disk.
As I have mentioned before, in my post[Supermarketsand Specialty Shops],companies are looking for complete solutions, preferably from a single vendor like IBM, HP and Sun, rather than buying piece part components from different vendors and hoping the combined ["Frankenstein"] configuration meets business requirements.
The DS4800 is an obvious choice for this solution, providing an excellent balance of cost and performance, in a modular packaging that is ideal for the incremental growth design inherent in the IBM Balanced Warehouse philosophy. To learn more about this disk system, see the official [DS4800 website] for details, descriptions and specifications.

You can choose between hardcover (with dust jacket) or paperback versions:
This is not the first time I've been published. I have authored articles for storage industry magazines, written large sections of IBM publications and manuals, submitted presentations and whitepapers to conference proceedings, and even had a short story published with illustrations by the famous cartoon writer[Ted Rall].
But I can say this is my first blook, and as far as I can tell, the first blook from IBM's many bloggers on DeveloperWorks, and the first blook about the IT storage industry.I got the idea when I saw [Lulu Publishing] run a "blook" contest. The Lulu Blooker Prize is the world's first literary prize devoted to "blooks"--books based on blogs or other websites, including webcomics. The [Lulu Blooker Blog] lists past year winners. Lulu is one of the new innovative "print-on-demand" publishers. Rather than printing hundredsor thousands of books in advance, as other publishers require, Lulu doesn't print them until you order them.
I considered cute titles like A Year of Living Dangerously, orAn Engineer in Marketing La-La land, or Around the World in 165 Posts, but settled on a title that matched closely the name of the blog.
In addition to my blog posts, I provide additional insights and behind-the-scenes commentary. If you go to the Luluwebsite above, you can preview an entire chapter in its entirety before purchase. I have added a hefty 56-page Glossary of Acronyms and Terms (GOAT) with over 900 storage-related terms defined, which also doubles as an index back to the post (or posts) that use or further explain each term.
So who might be interested in this blook?
- Business Partners and Sales Reps looking to give a nice gift to their best clients and colleagues
- Managers looking to reward early-tenure employees and retain the best talent
- IT specialists and technicians wanting a marketing perspective of the storage industry
- Mentors interested in providing motivation and encouragement to their proteges
- Educators looking to provide books for their classroom or library collection
- Authors looking to write a blook themselves, to see how to format and structure a finished product
- Marketing personnel that want to better understand Web 2.0, Second Life and social networking
- Analysts and journalists looking to understand how storage impacts the IT industry, and society overall
- College graduates and others interested in a career as a storage administrator
And yes, according to Lulu, if you order soon, you can have it by December 25.

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.
