The blogosphere has quieted down a bit over the two papers on MTBF estimates for Disk Drive Modules (DDM).One article on SearchStorage.com by Arun Taneja asksIs RAID passé? Disk capacity is growing at a faster rate than DDM reliability. During the hours to rebuild a DDM, companies are at risk of additional failures that could require recovery from a copy, or result in data loss, depending on how well your Business Continuity (BC) plan is written and followed.
I'll discuss two comments in particular.
Both are fair comments. Disk arrays do run microcode to assist or perform the RAID function, detect failures and start the rebuild process, and so clever designs to support spare disks, process the rebuild quickly, and so on, can differentiate one vendor's offering from another.
On the issue of what does IBM provide to help its clients make the right decisions for their environments, Jon William Toigo at DrunkenData points his readers to IBM's Business Continuity Self-Assessment tool. In normal data center conditions, DDMs will fail, and a Business Continuity plan shouldbe written and developed to handle this fact. Using 2-site and 3-site mirroring, complemented with versions of tape backups, can help address some of these concerns and mitigate some of the risks involved with using disk systems.
For those who want a more technical answer, IBM has just published a series of IBM Redbooks.
Yesterday, most of the USA moved its clocks forward an hour. Arizona and Hawaii don't bother, as there is plenty of daylight in both states. While it may seem that Arizonans are not "affected" by Daylight Saving Time (DST), we are, because we have to deal with the time zone offsets with those we talk to in other states. (Note: it is SAVING not SAVINGS, many people mistakenly say "Daylight Savings Time", which is incorrect).
Year round, Arizona is on Mountain Standard Time (MST), which is GMT-7. Figuring out what time Arizona can be remembered by a simple mnemonic:
Those in Second Life may have noticed that "Second Life time" (SL time) shifted from PST to PDT. That is because their servers reside in San Francisco, California.
On the news today, they mentioned it was "Happy Pi Day". Today is the 14th day of the 3rd month, and "pi" is about 3.14159, the ratio of the circumference of a circle to its diameter. So, in Tucson it is celebrated on 3/14, at 1:59pm MST.
The ratio has a lot to do with storage.
The value of "pi" has been calculated to over a billion significant digits. Here is a cuteapplet to use if you ever need the value to any level of accuracy.
Robert Von Oech on CreativeThink remembers Ernest Gallo, who died last week at 97 years old.
"Do you know what I do?" Mr. Mondavi recalls Mr. Gallo asked him when they first met.
Robert Smith (aka Radio Voom) reports on National Public Radio that Second Life is now being used for campaigning for political candidates. It used to be that political candidates took trains and buses across the country, meeting people, discussing their issues, and getting a feel for what is going on in the hearts and minds of their potential voters. With the development of TV and Radio, candidates traveled less, hoping to get their word out to people who would listen to them. Using Second Life and other social networking tools brings candidates back to having conversations with the people they hope to represent.
Of course, many of these candidates are old, and are learning internet social networking skills for the first time. John McCain, my senator from Arizona, is running for President at 70 years old! It's true that old dogs CAN learn new tricks.
IBM is investing heavily into Second Life, as are many other forward-thinking companies, to explore the age-old human need for connectedness, community and dialog. I've asked my team to all get their avatars up and running in Second Life. Granted there is a bit of a learning curve, but everybody handles change in different ways, some better than others.
John Windsor on YouBlog,Marina Krakovsky inStanford Magazine,and Guy Kawasaki, all discuss the "Effort Effect" and Carol Dweck's latest book "Mindset: The New Psychology of Success". I haven't read the book yet myself, but the reviews are interesting. The IT industry is evolving fast, and embracing new technologies, new concepts, and new ideas is necessary for success.
Seth Godin takes this one step further, arguing there are two kinds of people in this world: Thrill Seekers and Fear Avoiders. Forbes just published its latest list of billionaires. The front quote on Forbes' website says it all...
"Knowledge is the antidote to fear."
Why are most of these guys (and girls) with over a billion US dollars in net worth still working? Perhaps because they embrace new ideas, and are on the thrill seeking side of humanity. I guess I am too. I'll be thrill-seeking in Chicago this weekend, celebrating St. Patrick's day.

Last Friday,The "Greater IBM Connection" team held a "red carpet" event, showcasing the winners of the Second Life "machinima".It is best explained on the Linden Lab website:
Machinima is the art of making real movies in virtual worlds.
The seven videos were shown in Second Life, and are now available on YouTube for those who missed them.

The movie industry is slowly making the conversion to digital.
For about 25 years, movies were silent, actors acted, text was shown on the screen, and an organ or piano player added the musical score. My mother was a concert pianist, so I grew up listening to all kinds of piano music. Last weekend, while I was in Chicago for St. Patricks Day, we watched and listened to the dueling pianos at a bar called "Howl at the Moon". Those not familiar with this art form can watch this 1-minute video of Star Wars re-imagined as a Silent Movie.
About 80 years ago, "talkies" appeared. The sound was converted to a series of colors that were recorded as a separate strip on the film media itself, hence the name "soundtrack". When the movie ran, the colors would then be converted back to voice and music. While the live piano players were out of jobs, the move to sound created a whole new industry for foley artists, orchestras and comp Now the movie industry is changing again, this time from film to digital format. Thanks to digital, we can now see videos on the internet, such as this set of Impressive Palindromes parody of a Bob Dylan song. While movies are digital when you rent them from the DVD store, download them on iTunes, or play them on YouTube, they are still mostly in analog format on 35mm or 70mm film stock when you see them on the big screen. My first "digital projection" experience was the movie "Ice Age" shown in Denver, Colorado. The theatre owner came out to show us what film stock looks like, and then how small the DVD was that held the digital version. The theatre also showed previews of other movies first on film, then in digital, so that we could see the difference in quality.My second experience was "Star Wars: Attack of the Clones (episode II)", which I saw opening night at the Ziegfeld theatre in New York City. This was a huge theatre, and we had front row seats in the upper balcony. Of course, the transition of film stock to digital projection is just one of the many trends resulting in the fast growth of computer IT storage. Documents transitioned from paper, to being scanned into digital format, to being created digitally using word processing software. Likewise, photographs went from film, to being scanned, to being captured with digital cameras. As with talkies, history repeats itself; the transition to digital projection is not going smoothly.NPR's Laura Sydell reports thatDigital Projection in Theaters Slowed by Dispute. The dispute is between movie production companies and theatre owners. Currently, it is quite expensive to send out film stock to all the theatres, so the transition to digital will save the movie production companies lots of money. On the other hand, installing digital projection equipment will be costly for theatre owners. How the two groups will share the burdensome costs to convert this infrastructure is still under negotiation. As a fan of going to the movies, I hope they resolve this dispute soon.

The amount of information stored and available today is astounding. Consider the following:
...a weekday edition of The New York Times contains more information than the average person was likely to come across in a lifetime in seventeenth-century England.
Shawn Callahan mentions this in his great presentation on how work really gets done.
Mark Nelson covers this in more detail inWe Have the Information You Want, But Getting It Will Cost You: Being Held Hostage by Information Overload.
To help address this challenge of organizing finding the right information at the right time, Web 2.0 technologies have emerged. You can read the 16-page paper What Is Web 2.0? -- Design Patterns and Business Models for the Next Generation by O'Reilly.
Or better yet, watch the quick 4-minute video Web 2.0 ... The Machine is Us/Ing Us.Read More]
As an alumni of the University of Arizona, it is always good to see any of the Arizona schools try something new and innovative. This time, it was our arch-rivals atArizona State University (in Tempe, AZ, near Phoenix).
An article in InformationWeek reports that40,000 ASU Students Leap to Google Apps; University Pays Zero. The ASU president, Michael Crow, wants to make IT the primary driver in his ambitious "New American University" project.Last October, ASU became the first large institution to deploy Google Apps, a comprehensive suite of productivity applications that includes e-mail, search, calendars, instant messaging, and even word processing and spreadsheets.I've tried them out, they work, nothing fancy but certainly good enough for college homework assignments.
Already 40,000 students and faculty have switched their e-mail to Google, while keeping their asu.edu designation. (out of 65,000 student population, which Mr. Crow is trying to raise to 90,000 students!)
E-mail is a thorn in the side of storage administrators. Being "semi-structured" repositories, they cannot just delete or move files around, as there is context between notes and their attachments, that shouldn't be broken. E-mail systems are often the fastest growing consumer of storage for many organizations.
Switching from maintaining their own mail servers to Google is saving ASU $500,000 US dollars alone, not including the administrator labor savings. Again, some corporations might feel their e-mail is too "secret" to be outsourced like this, but for college students who spend all their creative talent posting things on MySpace and YouTube, and faculty who spend their careers TRYING to get published, they have nothing to hide from the rest of the world. It makes perfect sense.
Best of all, Google isn't charging ASU anything for this service. Google is able to cover the costs from advertising revenue instead. I can think of a lot of companies that might want to advertise to a demographic of "40,000 students who are mostly 18-25 years old and all live in or near Tempe, AZ".
It's good to see IBM TotalStorage Productivity Center evolve and expand. I was the lead architect for this product a few years ago, and my has it come a long way from its early beginnings.
Today, Gartner, Inc. has IBM Positioned in Leader Quadrant for Storage Resource Management and SAN Management Software.
The Magic Quadrant is copyrighted concept by Gartner, representing a two-by-two grid that ranks various offerings from different vendors. Ideally, vendors want their products in the upper right "Leaders" quadrant. Yahoo Finance reports:
According to Gartner, Inc., "Leaders have the highest combined measures of an ability to execute and a completeness of vision. They have the most comprehensive and scalable products. They have a proven track record of financial performance and an established market presence. In terms of vision, they are perceived as thought leaders, having well-articulated plans for ease of use, how to address scalability and product breadth. For vendors to have long-term success, they must plan to address the expanded market requirements for change management and root-cause and performance analysis. Leaders must not only deliver to the current market requirements, which continue to change, but they also need to anticipate and deliver on future requirements. A cornerstone for leaders is the ability to articulate how these requirements will be addressed as part of their vision for resource management. As a group, leaders can be considered a part of most new purchase proposals, and they have high success rates in winning new business."IBM TotalStorage Productivity Center is a strategic part of IBM Service Management, and a foundational component of the IBM Systems Director family. IBM is making a concerted effort across servers, networks, software and storage to help manage the IT infrastructure in a coordinated way.
I have seen other quadrants used to help explain different market segments, such as the one used in this 40-minute video Guy Kawasaki’s Art of the Start speech at TiECon 2006.
To the current architects and developers of Productivity Center, well done!
Today was our annual "State of the Site" meeting for the IBM Tucson site. This facility was completed in 1978, and I started my career here in 1986.
Various employees and teams were recognized for the contributions and dedication. For example:
Our site manager, Terri Mitchell, did a recap of all our recent awards and accomplishments.Of the nine Design Innovation awards won by IBM this year at the CeBIT conference, eight were for IBM System Storage products!
A representative from Tucson's Brewster Center presented Terri an award, thanking IBM for its strong support for the community through various charity initiatives.
The final speaker was a new IBM client, Tony Casella, the IT Director of the town of Marana. Recently, the town of Marana selected IBM products made big news. Arizona is the fastest growing state in the USA, and the town of Marana, just north of Tucson, is one of the fastest growing communities in Arizona. The town is growing so large that it will soon spill over from Pima into Pinal county, and will be the first town in Arizona authorized to span county boundaries.
Marana is most famous for its Gallery Golf Club on Dove Mountain that is the new home of the World Golf Cham His decision was based on conversations he had with other IT directors of other towns and cities, and this November 2006 article in Network World. He held up the copy of his magazine. Tony was very delighted with IBM's solution-oriented approach, rather than just selling more boxes of hardware. He found IBM easy to do business with, and committed to his success. technorati tags: IBM, Tucson, Tom Beglin, Jack Arnold, Michael Scott, Second Life, Terri Mitchell, CeBIT, design, awards, NEBS, disk, tape, NAS, Tony Casella, Marana, Arizona, Accenture, Golf, Championship, Network World, HP

Several of my IBM colleagues will be attending the "Virtual Worlds 2007" conference today and tomorrow. This conference sold out so quickly that they have already scheduled a second one for October. The focus is on 3-D internet technologies likeSecond Life. Attendance is expected at over 600 people.
IBM is investing heavily in this new concept of v-business. Last year, I was one of only 325 IBMers on Second Life. Now, according to this Better than Life blog entry from Grady Booch, IBM Fellow, the number is over 4000!
Of course, the challenge for IBM, and others, is learning to market in virtual worlds. Already, my team is in-world, and we meet several times a week. Using Second Life is quickly becoming an essential business skill, like participating in conference calls, or responding to instant messages.
What does meeting in-world entail?
I suspect the need for having places in Second Life to hold meetings will become more and more in demand.At a time when real-estate sales in the US is slowing down, Coldwell Banker's Second Life efforts are ramping up. I am not making this up. Coldwell Banker is one of the nation's largest real estate brokerage firms. They are trying to bring the same "adult supervision" to virtual real-estate transactions, offering to help people buy and rent properties in Second Life.
We live in interesting times!
In case you missed it, IBMunveiled a new digital video surveillance service yesterday. This "marks an important shift in the industry's approach to security, applying advanced analytics to video data and signaling the ability to converge physical and information technology (IT) security."
The IBM Smart Surveillance Solution is designed to provide the unique capability to carry out efficient data analysis of video sequences either in real time or from recordings. These recordings can be on disk or tape storage.
The problem with today's existing "analog" surveillance is that the analog cameras record onto traditional VHS tapes, and these are rotated through, re-written after a few hours or days. To review tapes often involves human intervention, and must be done before the VHS tapes are re-used. Many shoplifters, thieves, and other law-breakers take a chance that their actions will not be caught on tape, or that they will be long gone by the time the video is analyzed.
The IBM Smart Surveillance Solution can provide a number of advantages over traditional video solutions, including:
With real-time analytics capabilities, the new DVS service can open up a wide array of new applications that go far beyond the traditional security aspects of surveillance systems. Early adopter industries in this rapidly evolving market include retail, public sector and financial services. The retail industry estimates nearly $50 billion is lost annually to fraud, theft and administrative errors.
Once in digital format, video surveillance can be sent further, processed quicker, and stored for longer periods of time, than traditional media makes practical today.
Beyond fraud and theft, this kind of solution could also help identify bullies who makedeath threats in High School.
The terms "information" and "data" are often used interchangeably in regular usage, but for the storageindustry, there are significant differences between the two, as different as "fact" from "meaning".
For example, if you are walking down the street, and see a pole with red and white stripes, the data of red and white stripes may not have much meaning, unless you recognize the information is that you are in front of a barber shop.I thought of this when someone pointed me to theStrip Generator Tool website, which can helpyou generate various stripes for use on the tiled background of web pages. (Or if you aredesigning neckties for your Second Life avatar).
Many national flags are based on simple stripes of different colors.For example, look at the national flags of France, Russia, and the Netherlands. These consist of a red, white, and blue stripe, justin different sequence and orientation.Again, the data of these colors, the width of their lines, and the way they are placed on the flag are all data, but the information they convey is significantly more than that.One person might walk right by the flag, not knowing which country it belongs to, while anotherperson might get emotional memories of their homeland.
For those of us in the storage industry, data is just binary 1's and 0's on disk and tape media, and canbe treated like packages at the post office in brown wrapping paper. Just as post office employees don't have to know the contents to ship them to the final destination, servers and storage devices don't need to knowthe informational content of the data that they process and store.
Converting information to data is easy. Let's take an example of taking a digital photo. The photo could be a picture of you and your spouseon your last vacation trip, but you would never know that from just looking at a series of 1's and 0's. For this reason, you create photo albums, you write captions below indicating where and when the photowas taken. This additional "context" is often called "metadata" or just simply "indexing".
Both the information captured (the photo in this case) and its metadata (the caption), can be storedas 1's and 0's on storage media. These bits can be compressed, encrypted, or represented in a variety of formats.
Information is copied from one data file to another. In the traditional sense, one piece of informationcould exist in the primary production copy, as well as multiple archive or backup copies. One piece ofinformation, stored on multiple copies of data. In a sense, this is similar to genetic information storedon each human being (data copy). Richard Dawkins, author of The Selfish Gene, reminds us that genes outlive individual humans. In storage, we remind people that data outlivesthe media it is initally written to, and the information outlives the initial data copy stored.
Converting data back to information is not always as simple.Not all sequences of 1's and 0's are obvious what they represent. To display a digital photo, you need to know the format the photo is in, and have an appropriate application that can display it back to something a human person can recognize. If the bits were compressed, the application needs to handlethat, or you need to de-compress the data before handing it to the application. For encrypted data,you need to have the decryption key. The process of converting a single file of data back to information is called "rendering".
One of the big problems with keeping information for long periods of time, isthat you may not have the equipment, decryption key, or applications needed to render the data back to usable information. You've kept the data, but you can't make any sense of it, as if it went through an episode of Will it Blend?
A good example is how the current version of Microsoft Office application is unable to interpret andrender data documents that were stored in WORD 1.0 format. IBM and others have developed "rendering tools" that can help decipher the bits, and bring back the information. To help address this challenge, the new Microsoft Office 2007 haschosen the OOXML format, but will continue to support some of the older legacy formats. IBM and the rest of the world are focused instead on Open Document Format (ODF) open standard. Those of usstill using older versions of Microsoft Office might need the Office 2007 Compatibility Pack.
Another way to get information from data is "data mining", an important part of "business intelligence". Here you are gleaning information notfrom individual details, but from patterns in the data, averages, statistics, totals, that havebroader meaning than individual transactions or events.
For many applications, DLM is just fine. Let's consider e-mail, for example. For most employees,deleting e-mails larger than 1 MB, after 90 days, regardless of content, is probably a reasonable DLM policy. All data is treated the same, based purely on the size and date markings on the outer brown wrapper.
For more sensitive content, DLM is not enough. The e-mails that are to or from the president of thecompany, or between top executives, or that contain certain pieces of information relevant for lawsuitsor other investigations, may not be treatedthe same as other e-mails. In this case, you need ILM technologies, managing based on the informational content of the data, and not just the size and date last referenced.
Of course, IBM supports both, and can help you decide the right solution for each workload.

Today,Apple and EMI announced that EMI’s entire music and video catalog will be available in May without any digital rights management (DRM) protection.Not only with the music be higher quality, but can be played on any player, presumably using MP3 format instead ofApple's proprietary AAC format. Being locked into any single vendor solution is undesirable. Similar issues abound for Microsoft Office 2007 file formats.
On my iPod, I ripped all my CDs into MP3 format, not AAC. I love my iPod, but if I ever decided to chose a different MP3 player, I did not want to go through the time-consuming process or re-ripping them again.
A blog by Seth Godin feels this Apple-EMI announcement means thatDRM is dead.
Back when music labels added value by producing and distributing music in physical form, it made sense for them to take a cut. Mass-producing CDs and distributing them out to music stores across the country costs lots of money. However, for online music, music labels don't have these same overhead costs, but continue the process of paying the artists only a few pennies per dollar. Some artists have file lawsuits to get their fair share.
This process applies to any published work. For example, you can purchase Kevin Kelly's book in various formats, at different prices, from different distributors. For example:
It's good to have choices again.
The "corporate bloggers" from the various storage vendors often mention their opinions about IBM products. Sometimes, they say something nice, and other times they poke fun. It's good to read the various opinions. Most are well-thought and well-written.
EMC blogger Chuck Hollis has a post about the various categories that industry analyst IDC used for external controller-based disk in their most recentQ4 Storage Scorecard.I agree with Chuck that it is good to have independent analysts that take an objective look across all storage vendors to provide the facts on various makes and models. Both IBM and EMC took marketshare in 4Q, so we cancongratulate ourselves and each other for the efforts needed to make this happen.
Chuck mentions that while EMC and HDS high-end boxes are similar, perhaps IBM's "DS" series is different enough to question putting it in the same "high-end" category. It's not clear if Chuck is poking fun at the fact that theIBM DS family spans multiple categories; or an admission thatthe IBM DS8300 Turbo is faster than the EMC DMX-3 and HDS USP offerings. Perhaps we need a new categorycalled "super high-end"?
IDC doesn't publish their data by price band, but we can infer from the products in each how they decidedwhich products were grouped into which categories. Let's examine the entire IBM DS family in the various categories.
Storage is a competitive marketplace.Both EMC and HDS are reputable companies that make quality products that attach to IBM System z mainframe servers.

It is perhaps coincidence that I learned that two people have blogs today.
For that matter, I too plan to be at the SNW conference, so if you see me, stop and say Hello also.
Today I'm sitting in an airport, delayed due to weather.
Dick Benton of Glasshouse Technologies has an article on SearchStorage.com titled Justifying your storage staffing.
The concept that there should be a linear "Storage Administrators per TB" rule-of-thumb has been around for a while.Back in 1992, I went to visit a customer in Germany who had FIVE storage admins for 90 GB (yes, GB, not TB) disk array.I told them they only needed 3 admins, but they cited German laws that prohibited "overtime" work on evenings and weekends.
Later, in 1996, I visited an insurance company in Ohio to talk about IBM Tivoli Storage Manager. They had TWO admins to manage 7TB on their mainframe, and another 45 people managing the 7TB across their distributed systems running Linux, UNIX, and Windows. My first question, why TWO? Only one would be needed for the mainframe, but they responded that they back each other up when one takes a 2-week vacation. My second question to the rest of the audience was... "When was the last time you guys took a 2-week vacation?"
Today, admins manage many TBs of storage. But TBs are turning out not to be a fair ruler to estimate the number of admins you need. It's a moving target, and other factors have more influence that sheer quantity of data.Let's take a look at some of those factors, which we call "the three V's":
So, the key is that there is no simple rule-of-thumb. Fewer admins are need per TB on mainframe than distributed systems data. Fewer admins per TB are needed when you deploy productivity software, like IBM TotalStorage Productivity Center. Fewer admins per TB are needed when you deploy storage virtualization, like IBM SAN Volume Controller or IBM virtual tape libraries.

Yesterday, I went to the Bodyworlds exhibition. Here the anatomy of real human cadavers are on display, in full detail, thanks to a process call In the exhibit, you got to see the bones, nerves, muscles, digestive tract and other organs.Some in action poses, like swinging a baseball bat or ice skating, while others were stretched into specific poses to help emphasize one part or another. In some cases, they would show side by side healthy and unhealthy organs, for example, the lungs of someone that smokes tobacco cigarettes, compared to the lungs of a normal person. Quite a difference! Visualization can be an effective way to understand and gain insight from information. Presenting information in a visually stunning manner can be challenging, but often worth the effort. It reminded me of Edward Tufte, who has written several books on this subject.

Last year in Beijing, China, one of my colleagues told me "When it rains here, cabs dry up". Normally, there are enough taxi cabs to handle normal conditions, but when it rains, people who normally walk now want to take a cab instead, and the demand goes up, resulting in being more difficult to find one when you need one.
I'm wrapping up my week here in Chicago, and it snowed yesterday. Cabs were scarce. I walked. Many others walked too, about half with umbrellas to protect themselves against the snowflakes.
Most systems are designed to handle typical average conditions. Taxi cabs in a city, for example, handle typicalamounts of traffic.
IT is different. In many cases, IT infrastructures are designed for the peaks, not the averages. Peaks can be where you need performance the most, and failure to design for peaks can be disastrous. As with any business decision, this represents a trade-off. Design for the average, and suffer through the peaks, or design for the peak, and be over-allocated and under-utilized most of the time otherwise.
The choice is yours.
Well, I'm here in San Diego for Storage Networking World (SNW) conference.
If you're in San Diego, stop by and visit me at the IBM booth. Here is my schedule:
