Continuing my business trip through Canada, an article by Richard Blackwell titled [The Double Bottom Line] yesterday's Globe and Mail newspaper caught my attention.Here is an excerpt, citing Tim Brodhead, president of the J.W. McConnell Family Foundation in Montreal:
The bottom line for any business is making a profit, right?
But how about considering a different, or additional bottom line: helping make the world a better place to live in.
That's the radical proposition underlying the concept of "social entrepreneurship," the harnessing of business skills for the benefit of the disadvantaged.
Young investors, in particular, now want their investments to produce both financial and social returns, he noted.
Until recently, "we could either make a donation [to a charity] and get zero financial return, or we could invest and get zero social return." People now want more of both, but rules governing charities and business make that tough to accomplish.
One stumbling block is the imperative - entrenched in corporate law - that managers and directors of for-profit companies have a fiduciary duty to maximize profits. That structure is a brick wall that limits the expansion of social entrepreneurship, Mr. Brodhead said.
Some companies have embraced the new paradigm of a double bottom line, even if they are uncomfortable with the "social entrepreneur" label.
This fiduciary duty to maximize profits is discussed in the 2003 documentary[Corporation]. However, some organizations are now trying to aligntheir goals, finding ways to benefit their investers, as well as society overall. For example, organization [ONE.org] helped launch [Product (RED)]:
If you buy a (RED) product from GAP, Motorola, Armani, Converse or Apple, they will give up to 50% of their profit to buy AIDS drugs for mothers and children in Africa. (RED) is the consumer battalion gathering in the shopping malls. You buy the jeans, phones, iPods, shoes, sunglasses, and someone - somebody’s mother, father, daughter or son - will live instead of dying in the poorest part of the world. It’s a different kind of fashion statement.
The company, which has operated in Africa for nearly six decades, expects to increase its investment by more than $US120 million (more than R820 million) over the next two years. In the coming year, IBM expects to hire up to 100 students from Sub-Saharan universities to meet the growing demand in services, global delivery and software development.
"The Sub-Saharan African market is poised for double-digit growth flowing from the development and expansion of telecommunications networks, power grids and transport infrastructure," said Mark Harris, Managing Director, IBM South and Central Africa. "Private and public sector investment in the region is transforming the ability of the market to participate in the global economy."
A recent IBM Global Innovation Outlook (GIO) [report on Africa] indicates that the economies ofdozens of African nations are growing at healthy rates, the best in the past 30 years, with 5.5 to 5.8 percent averageacross the continent. This supports last month's news that [Top IBM thinkers to mentor African students]:
Hundreds of IBM scientists and researchers will mentor college students in Africa. Called Makocha Minds (after the Swahili word for "teacher"), the program will reach hundreds of computer science, engineering and mathematics students.
Makocha Minds is an off-shoot of IBM’s Global Innovation Outlook, an annual symposium of top government, business and academic leaders that uncovers new opportunities for business and societal innovation. "African students need to be trained in entrepreneurship so that they get out there and not just make jobs for themselves but create opportunities to employ others as well,” said Athman Fadhili, a graduate student at the University of Nairobi (Kenya).
Most of the mentoring will be via email and online collaboration.
Mentoring via email and online collaboration is very reasonable. I have mentored both high school and collegestudents through a partnership between IBM Tucson and the Society of Hispanic Professional Engineers[SHPE]. While thekids were all located in Tucson, I rarely am, traveling nearly every week, but I madetime for the kids via email and online collaboration wherever I happened to be.
To make this work, we need to get email and online collaboration in the hands who need them.I got my email thanking me for being a "first day donor" to the One Laptop Per Child "Give 1 Get 1" (G1G1) project,and have added this "badge" to the right panel of my blog. If you click on the badge, you will be takento a series of YouTube videos that further describe the project.
According to the email my donated XO laptop will soon be delivered into the hands of a child in Afghanistan, Cambodia, Haiti, Mongolia or Rwanda.
How do these work? Instead of buying your uncle yet another $25 necktie, consider buying a $25 Kiva certificate.The $25 dollar "micro loan" goes to someone in the third world to improve their situation, start a business, geta job, and so on, and you give your uncle a Kiva certificate so that he can track the progress. I think that isvery clever and innovative.
IBM doesn't publicly report subset numbers on individual product lines, but we are growing, albeit single-digit growth, on the high-end with our IBM System Storage DS8000 and DS6000 series products. Single digit growth is not "booming", but it is what we expected in this space, so it is not like we are"feeling the chill" as Robin stated.Obviously, if the U.S. market overall is doing poorly, then it must be from something else. IBM's success appears to be from organic growth in our Asia and Europe markets, and taking marketshare away from the top two contenders, EMC and HDS. Here are my thoughts why:
EMC is remodeling its kitchen
Not happy with its status as #1 disk hardware specialty shop, EMC is admirably trying to redefine itself as an ["information infrastructure"] company, buying up software companies and introducing new storage services. [Byte and Switch] reports onEMC's recent acquisitions:
EMC is the latest vendor to pin its colors to the SaaS mast, revealing its plan to offer SaaS-based archiving services during its recent Innovation Day in Boston.
EMC gave another clear indication of its SaaS intentions last month, when it spent $76 million to acquire online backup specialist Mozy.
IBM has offered[Managed Storage Services] foryears through our Global Technology Services (GTS) division. Gartner recognized IBM as the #1 leader in storageservices, with three times more revenues than EMC in this space.
As with a restaurant that is remodeling its kitchen, it can expect a temporary drop inrevenue. If it is done right, customers will come back to a bigger brighter restaurant. If not, the restaurant re-opens as a much smaller lesser version of itself. Recent events this year might incent EMC to get that kitchen done quickly:
A recent [class-action lawsuit]might result in having EMC's "86 percent male" sales force goes to sexual harassment sensitivity training, takingtime away from selling high-end storage arrays in the field. Analysts consider "high-end" boxes as those costingover $300,000 US dollars. Because of the money involved, there is a lot of competition for high-end storage, so face-to-face time with prospective customers is crucial to making the sale.Anytime any vendor is mentioned in a lawsuit (andcertainly IBM has had its share in the past, as Chuck Hollis correctly points out in the comment below), priorities get shifted, and there is potential dip in revenues.
Dell acquires EMC's rival EqualLogic. Dell resold EMC midrange storage, like CLARiiON, so this should notimpact their high-end storage sales. While Dell will be allowed to sell EMC until 2011, this new acquisition mightmean Dell leads with the EqualLogic offerings, and that could potentially reduce EMC revenues in the midrange space.
IBM went through a similar phase in the 1990's, redefining itself from an "IT Technology" company, intoa "Systems, Software and Services" company. These transitions can't be done in a quarter, or even a year, theytake several years. IBM lost business to EMC in the 1990s, but is back with a stronger portfolio in the 2000's, and so IBM's kitchen remodeling effort appears to be paying off. We will see what happens with EMC in a few years.
HDS puts on the white lab coats
Meanwhile, HDS appears interested in taking over as #1 disk hardware specialty shop.For years, Hitachi was the stereotypical JCM (Japanese IBM-compatible manufacturer) that made well-engineered"me, too" storage arrays. They would see what innovators like IBM and EMC were doing, and copy them. Recently,however, they seemed to have changed strategy, introducing new featuresand functions on their high-end USP-V device, like[Dynamic Provisioning].
The problem is that customers don't want to feel like [Guinea pigs] in an experimental lab, especially withmission-critical data that they trust to their most-available, most-reliable high-end disk storage systems.Like IBM and EMC and the rest of the major storage vendors, Hitachi has top-notch engineers making quality products, but new features scare people, and so there is a lag in the adoption of new technologies.
In our youth, we might have preferred beer with recent born-on dates, and tequila aged less than 90 days. But as weget older, we switch to drinks like wine and whiskey, aged years, not weeks. The same is true for themarketplace. New start-ups and other "early adopters"might be willing to try fresh new features and functions on their storage systems, but more established enterprises prefer storage with more mature and stable microcode.Storage admins want to leave at the end of the day, knowing that the data will still be there the next morning. In tough financial times, many established companies want the technological equivalent to ["comfort food"], nothing spicy or exotic, but simplehearty fare that fills the belly and keeps you satisfied.
Recognizing this, IBM often introduces new features and functions on its midrange lines first, and position them accordingly. Once customers are comfortable with the concepts, IBM then can consider moving them into the high-end lines. For example, dynamic volume expansion was introduced on the DS4000 and SAN Volume Controller first, and once proven safe and effective, brought over to the DS8000 series. This strategy has served us well.
Well those are my theories. If you have a different explanation of why storage vendors are not doing well in thehigh-end, drop me a comment!
I'll love to hear from you (I post letters from authors!) about how you put the blook together. Many folks have used cut and paste from blog page into word processor. Others have simply backed up their blogs, then cut and pasted. Some folks had the foresight to compose their posts in a word processor before posting!
Anyway, I'd like to know whatever ins and outs you'd like to share. Thanks.
Well Cheryl, I couldn't find any email address to send you a response, so Idecided to post here instead and post a traceback on your blog.
Software: Office 2003 version of Microsoft Word on Windows XP system
Front matter: Title, Copyright, Dedication, Table of Contents, Foreword, Introduction
Back matter: Blog Roll, Blogging Guidelines, Glossary, Reference table, What people have written about me and my blog
According to Lulu, you could use OpenOffice instead with RTF files. I didn't try that. I did tryusing CutePDF to upload ready-made PDFs, that didn't work. I also tried saving text in PDF formaton my Mac Mini running OS X 10.4 Tiger, but Lulu didn't like that either.IBM now offers a free download of [LotusSymphony] that might be an alternative for my next book.
For my blook, the "Blog Roll" serves instead of a more formal [Bibliography]. I could have also includedonline magazines and other web resources.
Decision 2: Chapter Configuration
I reviewed other blooks to see how they were organized. I thought I might organize the blog posts by topic or category, but all the blooks I looked atwere strictly chronological, oldest post first. This of course is exactly opposite as theyappear on the web browser. I decided to keep things simple, with just 12 chapters, one for each calendar month.
Each chapter was separated by a section break with unique footers, starting on odd page number. The footers have the page numbers on the outside edges, so that even pages had numbers on the left, and odd pages on the right. I also added the name of the chapter and the book, like so:
--------------------------------| |---------------------------- 40 ................December 2006| |Inside System Storage.... 41
This was a lot of work, but makes the book look more "professional".
Decision 3: Cut-and-Paste
People have asked me why it took three months to put my blook together, and I explainedthat the cut-and-paste process was manually intensive. My posts are either HTML entereddirectly into Roller webLogger, or typed in HTML on Windows Notepad and cut-and-pastedover to Roller later. I have access to the HTML source of each post, as wellas how it appears on the webpage, and tried cut-and-paste both ways. Copying theHTML source meant having to edit out all the HTML tags. I hadn't even looked into the idea of "backing up" through Roller all the entries, but they would probably have been HTMLsource as well.
In turned out that copying the webpage directly from the browser was better, which retains more of the formatting,and automatically eliminates all of the pesky HTML tags. I wanted the printed versions to resemblethe web page version.
Microsoft Word indicates all hyperlinks as bright blue underlined text which I didn't like, so I removedall hyperlinks, to avoid having to pay extra for "colored pages". This can be done manually, one by one, or pasting with the "text only" option butthis removes out all the other formatting as well. (Specifying black-and-white interior on Lulu might have converted all of these automaticallyto greyscale, so I might have been safe to leave them in,which I probably could have done if I wanted an online e-book version with links active, ... oh well)
To indicate where the hyperlinks would have been, I wrapped all the linked text in[square brackets]. I have now gotten in the habit of doing this for future blog posts, soif I ever make another book, it will cut down the work and effort on the cut-and-paste.
Some of the items I linked to posed a problem. I had to convert YouTube videos to flat imagesof the first frame to include them into the book. Older links were broken, and I had tofind the original graphics. I also sent a note to Scott Adams related about the use of one of his Dilbert cartoons.
I decided to also cut-and-paste my technorati tags and comments. For comments I mademyself, I labeled them "Addition" or "Response". A few people did not realize thatI was "az990tony" making the comments as the blog author, so I changed all to say "az990tony (Tony Pearson)" to make this more clear, and now do this on all future blogposts to minimize the work for my next book.
Because I used a lot of technical terms and acronyms, Microsoft Word actually gave mean error message that there were so many gramattical and spelling errors that it wasunable to track them all, and would no longer put wavy green or red lines underneath.
I did all the cut-and-paste work myself, but since the website is publicly accessible,I could have gotten someone else to do this for me.Had I read Timothy Ferriss' book The Four Hour Work Week sooner,I might have taken his advice on [Outsourcing the project to someone in India]. I might consider doing this for my next book.
Decision 4: Numbering the Posts
I decided I wanted to standardize the title of each post. The date was not uniqueenough, as there were days that I made multiple posts. So, I decided to assign eacha unique number, from 001 to 165, like so:
2006 Dec 12 - The Dilemma over future storage formats (033)
Posts that referred back to one of my earlier posts within the book had (#nnn) added so that readers couldgo jump back to them if they were interested. This eliminated trying to keep track of pagenumbers.
Decision 5: Adding behind-the-scenes commentary
One of the reasons I rent or buy DVDs is for the director's audio commentary and deleted scenes. These extras provided that added-value over what I saw in the movietheatre. Likewise, 80 percent of a blook is already out in the public for reading, so I felt I needed to provide some added value. At the beginning of each month, I describewhat is going on behind the scenes, and then in front of specific posts, I providedadditional context. This could be context of what was going on in the blogosphere at thetime, announcements or acquisitions that happened, what country I was blogging from, orwhat unannounced products or projects that were being developed that I can now talk aboutsince they are now announced and available.
To distinguish these side comments from the rest of the blog posts,I decorated them with graphics. Searching for copyright-free/royalty-free clip-art, graphics, and photos that represented eachconcept was time-consuming. I shrunk each down to about 1 inch square in size, and changed themfrom color to greyscale. (LuLu conversion to PDF probably would have automaticallyconverted the color graphics to greyscale for me, in which case leaving them in full colormight have been nice for an e-book edition, ... oh well)
I did complete each chapter one at a time. So, for each month, I cut-and-pasted all the blog posts,tags and comments, then fixed up and numbered all the post titles, then added all the behindthe scenes commentary, and cleaned up all the font styles and sizes. I recommend you do this at least for the first chapter, so you can get a good feel for what the finished version will look like.
Decision 6: Adding a Glossary
I sent early copies of the books to five of my coworkers knowledgeable about storage, andfive local friends who know nothing about storage.
Some of my early reviewers suggested having an index, so that people can find a specific poston a particular topic. Others suggested I spell out all the acronyms that appear everywhereand put that into the Reference section, rather than on each and every occurrence inthe book itself. Both were good ideas, and my IBM colleague Mike Stanek suggested calling ita GOAT (Glossary of Acronyms and Terms). Acronyms are spelled out, and terms or phrasesthat need additional explanation have a glossary definition. For eachitem, I put the post or posts that uses that term. Some terms are covered in dozens ofposts, so I tried to pick five or fewer posts representing the most pertinent.
The glossary was far more time-consuming than I first imagined, with over 50 pages containingover 900 entries. I struggled deciding which terms and acronyms needed explanation, and which were obvious enough. On the good side, itforced me to read and re-read the entire book cover to cover, and I caught a lot of othermistakes, misspellings, and formatting errors that way. Also, I have a large internationalreadership on my blog, so the glossary will help those whose English is not their native language,and will help those readers who are not necessarily experts in the storage industry.
Decision 7: Designing the Covers
Up to this point, I had been printing early drafts with simple solid color covers. Lulu hasthree choices for covers:
Just type in the text, upload an "author's photo" and chose a background color or pattern
Upload PNG files, one for the front cover, one for the back cover, and chose the textand color of the spine.
Upload a single one-piece PDF file that wraps around the entire book.
I had no software to generate the PDF for the third option, so I decided to try the secondoption. My first attempt was to format the front title page in WORD, capture the screen,convert to PNG and upload it as the front cover. I did same for the back cover, with a smallpicture of me and some paragraphs about the book.
I chose a simple straightforward title on purpose. Thousands of IBM and other IT marketing and technicalpeople will be ordering this book, and submitting their expenses for reimbursement as work-related, and didn't want to cause problems with a cute title like "An Engineer in Marketing La-La Land".
The next step was to use [the GIMP] GNU image manipulationprogram, similar to PhotoShop, to add a cream colored background, a slanted green spine, and some graphics that we had developed professionally for some of our IBM presentations.I learned how to use the GIMP when making tee-shirts and coffee mugs for our [Second Life] events, so I was already familiar. For newblook authors, I suggest they learn how to use this for their covers, or find someone who can do thisfor them.
I did the paperback version first, and once done, it was easy to use the same PNG files forthe dust jacket of the hardcover edition, adding some extra words for the front and back flaps.
The adage "Don't judge a book by its cover" seems to apply to everything except booksthemselves. The book cover is the first impression online, and in a bookstore. I have seenpeople pick books up off the shelf at my local Barnes & Noble, read the front and back covers, peruse the front and backflaps, and make a purchase decision without ever flipping a single page of the contents inside.From an article on Book Catcher [SELF-PUBLISHING BOOK PRODUCTION & MARKETING MISTAKES TO AVOID]:
According to selfpublishingresources website, three-fourths of 300 booksellers surveyed (half from independent bookstores and half from chains) identified the look and design of the book cover as the most important component of the entire book. All agreed that the jacket is the prime real estate for promoting a book.
While many struggle to find the right title and cover art, I think it is interesting that Lululets you post the same book with slightly different titles and covers, each as separate projects, and let market forces decide which one people like best. This is a common practice among marketresearch firms.
Decision 8: Finding someone to write the Foreword
With the book nearly done, I thought it would be a nice touch to have an IBM executive write a Foreword at the frontof the book. Several turned me down, so I am glad I found a prominent Worldwide IBM executiveto do it. I should have started this process sooner, as she wanted to read my book in its entirety beforeputting pen to paper. I had not planned for this. I was hoping to be done by end of October,but waiting for her to finish writing the Foreword added some extra weeks. Next time,I will start this process sooner.
Decision 9: Printing Early Drafts
You need to have Lulu print at least one copy to review before making it available to the public,and it doesn't hurt to order a few intermediary draft copies to make sure everything looks right.However, from the time I order it on Lulu, to the time it is in my hands, is over two weeks withstandard shipping, so I needed a way to print drafts to look at in between.
To avoid wear-and-tear on my color ink-jet printer, I went and bought a large black-and-white[Brother HL-5250DN] laser printer. Rather than buying specialty 6x9 paper, I used standard 8.5x11 paperusing the following 2-up duplex method:
Upload the DOC file to Lulu, and get it converted to PDF
Download the resulting PDF from Lulu back to your computer
View the PDF in Adobe Reader, and print it using 2-up "Booklet" mode.
For example, if you print 60 pages in booklet mode, it prints two mini-pages on thefront side, and two more mini-pages on the back side of each sheet of paper, resulting in 15 standard 8.5" x 11" pages that can be folded, stapled, and read like a mini-booklet. My entire blook could be printed on seven of these mini-booklets, saving paper, and giving me a close approximation to what the final book would look like. Eachmini-page is 5.5"x8.5", so just slightly smaller than the final 6"x9" form factor.I fount that 60 pages/15 sheets was about the maximum before it becomes hard to fold in half.
So, if I had to do it all over again, I might have chosen 11pt Garamond (the default), or changedthe default to 11pt Book Antiqua up front, so as not to have spend so much time converting thefonts. I might have left out the glossary. I might have left in all the hyperlinks and graphicsin full color for a separate e-book edition. And I definitely would have looked for an author formy Foreword much earlier in the process.
I didn't plan to write a blook when I started blogging. I have started putting [square brackets]around all my links. I have started putting "az990tony (Tony Pearson)" on all my comments. I hadassumed that people were jumping to all the links I provided in context, but I learned that the blogpost has to stand on its own, so now I make sure that I either paraphrase the important parts, oractually quote the text that I feel is important, so that the blog post makes sense on its own.This is perhaps good advice in general, but even more important if you plan to write a blook later.
Lastly, I decided up front to write blog posts that were 500-700 words long, about the average lengthof magazine or newspaper articles. In my blook, the average is 639 words per post, so I hit thatgoal. I have seen some blogs where each post is just a few sentences. Maybe they are posting fromtheir cell phone, or don't have time to think out a full thought, but who wants to read a year'sworth of [twitter] entries.
Well Cheryl, I hope that helps. If you need anymore, click on the "email" box on the right panel.
HealthAlliance Hospital has implemented an IBM System Storage Grid Medical Archive Solution (GMAS) to make patient records available to clinicians anytime, anywhere. IBM has a [Case Study] on this implementation.Here is an excerpt from the IBM [Press Release]:
HealthAlliance Hospital, a member of UMass Memorial Health Care, serves the communities of north-central Massachusetts and southern New Hampshire with acute care facilities, a cancer center, outpatient physical therapy facilities and a remote home health agency. As an investment in continued high-quality patient care, the hospital has implemented a picture archiving and communication system (PACS) from Siemens Medical Solutions so that it can move toward digital health records while eliminating traditional paper and film.
HealthAlliance is now able to make all of their data, including PACS images, available instantly, using the IBM GMAS, a cross-IBM offering comprised of storage, software, servers and services. The GMAS solution provides hospitals, clinics, research institutions and pharmaceutical companies with an automated and resilient enterprise storage archive for delivering medical images, patient records and other critical healthcare reference information on demand.
"Fast, easy access to diagnostic images is a priority," said Rick Mohnk, Vice President and Chief Information Officer of HealthAlliance. "Being paperless not only helps our staff improve their productivity and the quality of patient care, but also lowers our costs and improves our competitiveness. The IBM GMAS has helped us stay competitive and offer the leading edge technology that attracts top physicians to our staff and keeps patients feeling comfortable and well cared for."
Normally when you read or hear the term "grid", you might think of supercomputers, but in this case we are talking about information that is accessible from different interconnected locations. I've mentioned GMAS before in my posts [Blocks, Files and Content Addressable Storage and What Happened to CAS?] but I thought I would provide more detail on the elements of the solution.
Medical imaging equipment are called "modalities", which is just fancy hospital talk for "method of treatment".These have Ethernet connections designed to write to any storage with a CIFS or NFS interface. For example, press the button on the "X-ray" machine, and the digitized version of the X-ray is stored as a file to whatever NAS storage on the other end.
[Picture Archiving and Communication System] refer to the application and the computer equipment to manage these medical images, often stored in a DICOM format and indexed with HL7 metadata headers. There are many PACS vendors, GE Medical Systems, Siemens Medical, Agfa, Fuji, Philips, Kodak, Stentor, Emageon, Brit Systems, Mckesson, Amicus, Cerner, Medweb and Teramedica, to name a few. Many PACS providers embedded specific storage as part of their solution, but now are starting to realize that they need to be part of a larger storage infrastructure.
IBM System Storage [Multi-Level Grid Access Manager] is softwareon IBM System x servers that manages access across the grid of inter-connected hospitals, clinics and imaging facilities. It provides the NFS and CIFS interfaces to the modalities, and places the data into a GPFS file system on DS4000 series disk.
GPFS and DS4000 series disk
IBM [General Parallel File System] has all the Information Lifecycle Management (ILM) capabilities to move data from one disk storage level to another, automates deletion based on expiration date, and can provide concurrent access from multiple requesters.The IBM System Storage DS4000 series disk products can support both high-speed FC disk as well as low-cost SATA disk.For large medical images, the SATA disk is often a good fit. The advantage of GPFS is that you can have policies todecide which images are placed on FC disk, and which on SATA, and then later move these files based on access reference. Images that are accessed the most frequently can be on FC disk, and those that haven't been accessed in a while on SATA disk.
TSM space management
IBM [Tivoli Storage Manager for Space Management] supports moving files out of the GPFS file system and onto tape, based on policies. For example,keep the most recent 18 months on disk, and anything older than that gets moved to tape. This is similar to themigrate/recall technology used in DFSMShsm on the mainframe.
Tape Library automation
Before GMAS, paper and film images had to be retrieved manually from shelves and filing cabinets. The massive amountsof data being stored, and for such long periods of time, makes it impractical to store all of it on disk. With tape automation, any medical image more than 18 months old can be retrieved in minutes. Patients with an appointment can have all of their medical images retrieved in bulk the night before. Emergency room patients can have previous images retrieved while admission clerks check for insurance coverage and perform triage.
Images archived on the IBM GMAS are accessible in numerous ways. For example, all clinicians can access GMAS through hospital record system, which provides complete paperless and filmless access to the patient record including medical images, lab results, radiology reports, and pharmacy records. Medical workers at any location can also access the grid using their Web browsers. This allows each employee to use the display systems they are already familiar with.
Unlike disk-only based NAS systems, IBM's blended disk-and-tape approach makes this a much more cost-effective solution.For more details on IBM GMAS, read this 6-page[Frost & Sullivan whitepaper].
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.
