Chris Anderson, of Wired magazine, wrote a great article called The Long Tail.
This article became a book by the same name published earlier this year, and I just discovered it on a recent visit to Second Life. A lot of IBMers are now alsoSecond Lifers, and I suspect it is just a matter of time before we are conductingour customer briefings there, and getting our year-end bonuses paid directly in Linden bucks.(Those of you not familiar with Second Life can watch this 3-minute video fromthe folks at Text100)
Anyways, the Long Tail describes the new economy of entertainment thanks to digitalstorage. Here are some of the key insights.
In the past, entertainment was all about hits: hit songs, hit movies,hit novels, and this was primarily because of the economic realities restricted byphysical space. Chris writes: "An average movie theater will not show a film unless it can attract at least 1,500 people over a two-week run; that's essentially the rent for a screen. An average record store needs to sell at least two copies of a CD per year to make it worth carrying; that's the rent for a half inch of shelf space."
Things have changed. To drive the point home, Robbie Vann-Adibe (CEO of eCast), poses the trick question"What percentage of the top 10,000 titles in any online media store (Netflix, iTunes, Amazon, or any other) will rent or sell at least once a month?" The answer will surprise you. Write down your guess first, then go read here. His digital jukeboxes are able to play from a list of150,000 songs, not the few hundred you'd find at the Tap Room which is rated as having the best jukebox in Tucson.
The phenomenon is not just limited to music. "Take books," Chris writes, "The average Barnes & Noble carries 130,000 titles. Yet more than half of Amazon's book sales come from outside its top 130,000 titles. Consider the implication: If the Amazon statistics are any guide, the market for books that are not even sold in the average bookstore is larger than the market for those that are..."
This has incredible implications for the storage industry. For one, content providers are going to dig deep into their archives to digitize and deliver "long tail" offerings. If they don't have a deep archive, many will start to build one. Second, the need to search through that large volume of content will become more critical. Classifying and indexing with the appropriate tags and metadata will be an important task.
Well, there's little to no chance we'll get snow in Tucson the rest of this year, so I built a snowman out in Second Life. That's my avatar on the right, andI am an eightbar specialist. Eightbar refers to our logo.
This was part of an IBM "Holiday Party" where dozens of IBMers met "in the virtual world" to participate in 3D competitions,I entered the "Build a Snowman" competition, since I am still a beginner at this. This was whatI was able to come up with in 20 minutes that we had to get it done. Why I made mine out of woodwith different colors was so that I could stand out from the crowd. Everyone else used traditionalwhite snowy textures.
Others had a more challenging "Build a Snow Globe" where you have to write scripts to get thelittle snow flakes to move around. This for the advanced builders of our group.
This is still new, emerging technology, but eventually, Second Life and other MMOs could be used to market products,that people can view from all three dimensions, talk to a technical specialist, and get all questions answered.It could be used for education, shopping around, and collaborating with others.
Anyways, I haven't heard the results, but I had fun anyways.
In his blog, Paul Gillin agrees with Time Magazine's Person of the Year choice of "all of us", those of us who use the World Wide Web to do business or have fun, and to those who contribute to the internet by creating content, such as people who blog or create websites.
So, in continuing my theme this week to recap the best and worst of last year, I list my personal "tech highlights" of 2006.
Programming my Tivo Remotely.
Last September, I realized on a 3-week business trip that I had not programmed my Tivo to record the premieres of each of the new season's television shows. If you miss the first few weeks, it might be difficult to make sense of the rest of the season. Fortunately, I was able to program my Tivo remotely through the internet.
Purchasing TV shows on iTunes
Despite this, I had a repeat episode of "House" record instead of a new episode of
Still unable to make sense of what was going on in the TV show "Heroes", I was able to read the "wiki" which explained all the subtle imagery and background implied.
Using Linux to rescue lost Windows data
My disk drive failed on my laptop, and although I had most of my data backed up with Tivoli Storage Manager prior to my business trip, I had some files that I acquired or updated during the business trip. Thankfully, there are Linux "LiveCD" images that allow you to access your Windows files. You boot these LiveCD images from your CD drive, so there is no installation of Linux on the hard drive itself. If you travel as much as I do, consider bringing along some Linux CDs to get you out of trouble.
Connecting my home entertainment system to my Mac
I now have an 802.1g (54Mb) wireless hub which allows my Tivo to connect wirelessly to the internet to get daily updates, but also allows me to play all my music stored on my Mac through my home entertainment system, and I can also listen to thousands of radio stations through "Live365.com". My favorite station is "Depeche Mode Inspired" which plays songs by Depeche Mode, as well as cover versions by a variety of others.
Learning to Blog
Believe it or not, there is a right way and a wrong way to blog, and this year has been a good learning experience. IBM has a fairly healthy blogging policy, but nonetheless, say the wrong thing and I could be in serious trouble. Fortunately, that hasn't happened, and I am glad to see a fairly open exchange of ideas among the set of bloggers that discuss storage issues.
Building a Snowman in Second Life
I have been a member of Second Life now since November, but it wasn't until I entered a competition to build avirtual snowman last week that the potential of this new interface became obvious to me. There is still lots to learn, but at least now I see value in spending more time and effort learning more about it.
Getting an all-in-one printer/scanner to work with both my Mac and IBM PC
I didn't think it could be done, but here it is, my all-in-one Printer/Scanner works correctly, seemlessly, from both my Windows PC and my Mac Mini, and I have it on my home network so my laptop can use it also, wirelessly!
Using Google Language Tools to translate materials to Portuguese
I speak several languages, enough to order food in restaurants and to get around through various modes of transportation, but translation for a technical audience is more challenging. A class we normally conduct in pure English was taken to Sao Paulo, Brazil, and although most students know some amount of English, we thought it would be good to translate the test questions to Brazillian Portuguese. I took the questions and ran them through a number of translation services websites, and had local IBMers review the results. The winner was Google language tools, which required hardly any edits to the generated text. The class was a big success.
Digital Cameras and CD Burners
As I travelled from Brazil to Bolivia last August, I met a young back-packer who was on her way to Peru, but was staying in La Paz for a few days. We had a great time together, and I was able to transfer the digital photos from my Canon PowerShot digital camera into my laptop and burn her a CD to take with her to Peru.
Painting my Dining Room table
After Halloween, I accidently left my pumpkin jack-o-lantern on my kitchen table as I left for a trip, and when I got back, it had decomposed and left a terrible stain on the wood surface. After sanding the table, I determined that the best course of action was just to paint the surface. I could have just painted it a solid color, or maybe a faux finish with two colors, but instead, chose to copy a famous painting, "Le Cafe" by Alberto Magnelli. I was able to scan this into my computer, resize it, and then project the image onto my table, to then outline the image and paint. I know I would not have been able to do this free-hand.
I am sure there are other triumphs I had throughout the year, but these are the first the come to mind.
Today, I went looking for reading-glasses. Unfamiliar with my surroundings, I asked several people where I might be able to find and purchase these, and was sent in various directions. My first stop was a bookstore. It would make sense that since many people need reading glasses to read the books, that they would sell them there, but no. The staff didn't know where I could go, but pointed me in the direction of a mall. At the mall, I found a pharmacy. Many pharmacies sell reading glasses, so I stopped in, but no, not this one. The pharmacists suggested the super-store nearby. I walked in to the super-store, and asked the first employee where they keep their reading glasses, and they said the other corner. The other corner was the electronics department. It made sense that they sold CDs and DVDs in the same section as the equipment that plays them, but reading glasses? Skeptical, I went to the pharmacy department, and the young and beautiful lady (everyone is young, thin and beautiful here) had me follow her, and she led me back to the electronics department, whereupon she pointed to a rack of sunglasses. I indicated that I need reading glasses, not sunglasses. She pulled one out, and it was indeed reading glasses, 1.25, just what I was looking for. Others were tinted, so you can read the newspaper out in the sunlight. The pair I chose cost only $97 in the local currency.
After reading the last sentence, you might be thinking I am describing my "avatar" in Second Life, but no, I am talking about my search for reading glasses on the streets of Mexico. I am here this week in meetings with IBM Business Partners and sales reps to discuss IBM's latest System Storage products and offerings.
We used to tell people they should "clothe" servers with storage. IBM offers both, so yes it makes sense to offer both as part of a complete solution. However, when you look through a dictionary definition "to clothe" you learn it is to dress, wrap or cover with clothing, an implication that it is external, and perhaps temporary, easily changed, like switching from sunglasses to reading glasses. In Second Life, objects can be "worn", simply by attaching or detaching them to your "avatar". Sometimes clothing serves a purpose, like reading glasses, provides protection, like raincoats, and other times, more decorative, like"icing on the cake" or "gold plating".
This concept was fine 50 years ago, when we were in a server-centric world, and dumb storage devices were attached to very intelligent servers. Back then, we used the derogatory term "subsystems" to emphasize that storage was just part of the server, not a system of its own.
Today, we live in an information-centric world. The information outlives the media, and the media outlives the servers that access it. It is not unreasonable to attach dozens or hundreds of servers to a single storage system, or collection of storage systems. Over 20 percent of IBM System Storage DS8000 series, for example, are attached to Windows rack-optimized or blade servers. Imagine a refrigerator surrounded by dozens or hundreds of pizza boxes. Storage is no longer a subsystem, but a system on its own right, dressed, wrapped or covered by servers that deliver the right information, to the right people, at the right time.
So perhaps we should reverse it, telling people they should "clothe" their storage with servers!
Back in 1986, when I first started with IBM, my first job was working on a software product called Data Facility Hierarchical Storage Manager (DFHSM). This did "Information Lifecycle Management" (ILM) by moving data sets from one storage tier to another. (The phrase "Information Lifecycle Management" was coined by StorageTek in 1991, and later resurrected by EMC a few years ago. As is often typical, things that appear new to the distributed systems crowd, are often well-established concepts in the mainframe arena).
To help explain DFHSM and its sister product Data Facility Data Set Services (DFDSS), an enterprising sales rep in Los Angeles named C.D. Larsen made a video called "Re-arranging the sock drawer". He explained that sometimes you want the socks you wear the most on the top drawer, and socks that you only wear now and again in lower drawers. DFHSM can re-arrange your sock drawer based on policy-based automation, determining which ones you wear most often, and moving the others down the "hierarchy" accordingly.
To explain DFDSS, he pulled out an entire drawer of socks, and move it to another level. DFDSS was able to do volume-level backups and dumps to tape very quickly, since it did not process individual data sets, but rather the entire volume image as a whole. These two products are now DFSMShsm and DFSMSdss components of the DFSMS element of the z/OS operating system.
Mainframes use an interesting naming convention for its data sets. 44 characters, divided up into qualifiers that are 1-8 characters long, separated by periods. For example:
The first qualifier indicated it belonged to me, that it was for my Project A, that it was a testcase, and specifically TEST1 job control language. Arranging them in this order meant that I could easily find all the data needed for project A, but if I wanted to keep all the testcase data together, I might have put that as the second qualifer instead.
On Linux, UNIX and Windows, most people are more familiar with hierarchical file systems, so the same file might be stored as:
Same concept. You set up a taxonomy of they way you want to organize your data, so that related data can be grouped together and easier to manage. Whereas we used to tell customers that "Qualifiers are your friend", we now tell people "sub-directories are your friend". This is true when organizing the files on your laptop, in your Lotus Notes, and in Second Life.
Since starting Second Life last November, I have picked up all kinds of free things along the way, and now have thousands of objects in my "inventory". Basically, its like keeping things in your pocket, when you want it, you just take it out of your pocket, and *poof* it appears magically on the ground. I was having a hard time finding things in my inventory, so I decided to re-arrange with sub-folders. This is done in-world, and I found it best to do this away from other avatars asking "what are you doing?" which can get quite annoying. Find a remote island or the rooftop of some building when doing "house cleaning".
I've arranged my main folders as follows. These all appear on a single screen, and makes it easy to find exactly what I am looking for.
Lost and Found
In Second Life, you can make complete "outfits" which include your body shape, skin, eyes, hair, and clothes. However, saving away many outfits means duplicating a lot of items. Therefore, I separated them out. I keep body shape, skin, eyes and hair in the folder "Body Parts" and all of the clothing items under "Clothing". Under clothing, I separated everything out into the major categories:
I could have a separate folder for "socks", but I keep those in the "shoes" folder.
Sometimes, it's difficult to explain the products I manage to people outside the IT storage industry. How do you explain FCP vs. FICON, Giant Magnetoresistive (GMR) heads, the SMI-S interface, etc. enough to then explain how your job relates to those technologies. At least my friends and family read this blog, so they can somewhat understand some of the things I am working on. When I visit my folks on Sundays, we sometimes discuss items they read in my blog that week.
In addition to a "take your children to work day", we have discussed within IBM a "take your parents to work day", especially for the young new hires who have a hard time explaining what their new job is to the rest of their family.
The problem is not just your parents, but any of your co-workers old enough to be parents who haven't bothered to keep up with the latest advancements in Web 2.0 technology. Here are some examples:
A project leader working with a technology partner asked if me if there was a difference between a "blog" and a "wiki" and which should his team use. This was not a simple yes/no answer, and involved some explanation, conversation and understanding of what he was trying to accomplish.
For one of my meetings, someone instant-messaged me asking where it was, was it "face-to-face" (F2F) or Conference call (CC). I replied back, "A2A w/CC" (avatar-to-avatar with voice over conference call). When you are meeting other avatars in-world in Second Life, it gets quite distracting having everyone typing away, with their hands and fingers moving furiously, so we use a conference call to complement our 3D interaction.
That's why I was very excited to seeLinden Lab announces voice beta in Second Life. It won't be fully ready until later this year, but adding voice to Second Life will greatly reduce the hurdles we now have trying to coordinate conference calls with in-world activity.
I realize not everyone can keep up with all the new and different technologies, but the social networking aspects of some of these new developments are worth looking into.
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:
In the winter time, Utah, Colorado, New Mexico, and Arizona are all on MST, so best American ski resorts are all on the same time zone. People who hop from one ski resort to another by helicopter don't have to reset their watches as they move into or out of Arizona.
In the summer time, Arizonans head to San Diego, Los Angeles or other parts of California, where it is not so hot. California is on PDT, which is the same as MST. People who hop from Arizona wineries and vineyards to those in California and Oregon can easily cross the Arizona-California border without having to reset our watches.
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.
"Do you know what I do?" Mr. Mondavi recalls Mr. Gallo asked him when they first met. "Yes, you run the largest winery in the country," recalls Mr. Mondavi, then in his mid-20s. "No," Ernest corrected him. "I go out and visit customers in stores."
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.
"Knowledge is the antidote to fear." -Ralph Waldo Emerson
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.
Movies made in Second Life use the world's building, scripting, and avatar customization tools, working in real-time collaboration with people around the globe. You can use Second Life as your own virtual back lot, soundstage, choreography studio, costume and prop repository, and special effects house.
Michael Scott, one of my "Second Life" builder/scripters, for demonstrating client-focused dedication to IBM's corporate values.
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!
The IBM System Storage EXP3000: an entry-level data storage server that is optimized for cost-sensitive and space-limited environments and employs a user-centered design that enables ease of use and simple tool-less installation and removal of all components.
The IBM System Storage N7000 Series: a modular disk storage system that delivers high-end enterprise storage and data management value ideal for large-scale applications, while helping to anticipate growth, maintaindata availability and reduce costs.
The IBM System Storage N5000 Series: a modular disk storage system designed to address the entire spectrum of data availability challenges while offering value in price and scalability. Built-in enterprise serviceability and manageability features support efforts to increasereliability and simplify storage infrastructure and maintenance.
The IBM System Storage N3700: a filer that integrates storage and storage processing into a single unit, facilitating affordable network deployments.
The IBM System Storage DS4700: a NEBS-compliant disk storage server designed to address requirements for companies in the telecommunications industry, as well as other segments, such as oil and gas, meeting standardsfor electromagnetic compatibility, thermal robustness, earthquake and office vibration resistance, and provides protection for the product components from airborne contaminants.
The IBM System Storage EXP810: a data storage expansion unit capable of 4.8 Terabytes of physical storage, with a user-centered and tool-less design featuring redundant power, cooling, and disk modules for ease of use and simple serviceability.
The IBM System Storage TS3400: an affordable, space-friendly tape library for users in remote locations that supports enterprise-class technology and encryption capabilities.
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.
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?
Scheduling a time and a place
Finding a time that people can meet is no different than scheduling a audio or video conference call. In general, you don't have to worry about travel, but you do have to be actively somewhere connected to everyone else.
Finding a place involves actually determining the island, region and coordinates to hold the meeting. You need to find a place with enough seating. You don't have to worry about daylight, each person can control how much or little sunlight shows up on their screen. You do have to make sure you pick a spot that nobody else plans to use at that same time. Just like scheduling conference rooms at the site or hotel, we have to schedule rooms in advance.
To avoid this hassle, I have created the "pocket conference room". This is a single object that I can "rez" onto the ground, from my inventory, with 40 chairs, a PowerPoint presentation screen, a podium for a speaker to stand behind, and stools for speakers to sit on if they are next on the agenda. Now, I can hold impromptu meetings in any sandbox, grassy knoll, or the roof top of a building.
As with any other meeting, you need some basic ground rules. I am not talking the usual "no shooting, no gambling, no selling" rules that you see everywhere in Second Life. Instead, rules like an avatar must stand up before speaking. Anyone with a question must first "raise their hand" and get recognized by the chair. These ground rules can be as formal as Robert's Rules of Order or more casual, depending on who is participating.
It costs 10 Linden Dollars (L$) per PAGE to upload a PowerPoint presentation. This has the immediate benefit of having everyone spend more time and effort on their presentation, trying to cut down the number of charts, and focus more on what they are going to say.
Public Speaking Skills
It is amazing. People who are too scared to speak in front of an audience in Real Life have no problem having their avatar stand in front of other avatars in Second Life. This has greatly broadened the pool of speakers to tap into.Are you a woman with a husky masculine voice? Are you a man with a high-pitched feminine voice? Now, you can create an avatar that matches your voice.
This turns out to be the biggest challenge. In Real Life, organizing a face-to-face meeting involves time and effort making sure the venue has everything you need, a platform, a podium, good Audio/Video system, etc. All people have to do is show up, sit in a chair and listen.
In Second Life, however, the aspects of venue are all covered, but getting people to show up is another story. People have to sign up for Second Life account, create an avatar, wear appropriate virtual clothing, figure out how to teleport near the venue, walk or fly the difference to get to the exact building and room, master the sitting-in-a-chair and hold-coffee-and-sip-occasionally process, and pay attention.
Perhaps the best part of Second Life is that if you are not paying attention, your avatar noticeably falls asleep, into a hunched-over position, what is called "afk" (short for Away From Keyboard). On the other hand, if you do need to step away from your desk, you can put your avatar in "afk" mode immediately, tell everyone why and perhaps when you'll be back, and then re-activate when you return. This is one of the best improvements over regular audio conference calls.
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.
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.
We had a great event today! This was a first-of-a-kind product launch, using Second Life as the medium. We invited IBM Business Partners, industry analysts and reporters from the Press to have their "avatars" in-world to watch us launch new tape systems, archive and retention systems, and disk systems announced this month.
Andy Monshaw, IBM System Storage General Manager, welcomed everyone to the event, and introduced our three speakers.He mentioned that this was a great innovative way to meet, collaborate and forge relationships without the carbon pollution associated with travel required by a more traditional face-to-face meeting. We had attendees from the USA, UK, Germany, Sweden, Italy, Colombia, and Brazil.
All the attendees were given a "goody bag" that contained IBM BP-logo clothing, animations and gestures to be used during the meeting.
Eric Buckley, one of our marketing managers for tape systems, introduced our complete line of LTO 4 tape systems, as wellas the TS7520 Virtualization Engine, a virtual tape library for Windows, UNIX and Linux servers. Eric had a virtual 3-Dversion of an LTO cartridge that is photo-realistic and dimensionally correct.
Funda Eceral, our solutions manager for archive and retention offerings, presented the new version of the IBM System Storage DR550, the DR550 file system gateway, and the IBM System Storage Multilevel Grid Archive Manager. At first we thought we would "pass the microphone" from speaker to speaker, but it turned out to be easier just to give all three speakers their own microphone.
Last, but not least, was David Tareen, marketing manager for disk systems, covering the entry-level DS3000 Express disk system bundles designed for our SMB client. David used a black-and-brown pointer stick to point out specific things on the charts.
After the presentations, Kristie Bell, VP of Marketing for IBM System Storage, hosted a Question & Answer (Q&A) panel.Avatars rose their left hand to indicate they had a question.
We thought it would be a good idea to have a few minutes at the end to socialize over a cup of coffee. This involved making a "coffee machine" that dispensed coffee, and the appropriate animations and gestures so that everyone could sip the coffee, and hold the coffee at waist level when they were talking.
The event was held upstairs in one of the conference rooms of the IBM Briefing Center, located on "IBM 8" island.Many people went to the ground floor to look at the many IBM System Storage products on display. Unlike a picture on a web-page, Second Life gives you a 3-D view that you can walk around each product, and get a feel for the size and shape of the hardware.
We had four photographers and camera-persons on hand to capture still shots, video, audio, and chat text, and are working now to combine them for marketing collateral. I want to thank the builders, script programmers, animators, clothing designers, speakers, editors, and channel enablement team for making this event such a great success!
This week (actually April 29 to May 2) is IBM'sPartnerWorld 2007 conference.Over the past 10 years, IBM's shift to rely more heavily on business partners has proven to be a smart decision. IBM Business Partners can often focus on a specific region or industry much better, with laser-like focus.
Today was the "First Ever Live Virtual Virtualization Tech Fair" sponsored by IBM and VMware. This was a 1-day event hosted by Unisfair.
The day included presentations done at a conference call, along with exhibition booths.
We had an exhibition booth exclusively for "storage virtualization" featuring our IBM System Storage SAN Volume Controller (disk virtualization) and IBM System Storage TS7520 Virtualization Engine (a virtual tape library, or VTL).
People who were logged in were represented in silhouette form. When someone walked into the booth, our army of "booth reps" were able to chat with them and answer their questions. They could also peruse the various online materials we made available about each product.
Here are some of my observations:
A lot of questions were related to IBM's support for VMware. Although VMware is now currently owned by EMC, pending a spin-off IPO, IBM is its biggest reseller, given IBM's vast experience in server virtualization. Ironically, IBM's SAN Volume Controller supports VMware better than EMC's own storage virtualization product, Invista.
People also familiar with Second Life thought this 2-D "silhouette" version eliminated the need to configure and dress up your avatar as is required in participating in Second Life events. However, being only ableto chat, send e-mail and show web pages seemed less immersive than what Second Life can offer.
This event generated over 60 leads. We will pass on the contact information to the appropriate sales team.
Based on our success with Second Life launch event last week, see my previous blog posts hereandhere, people have asked me what tools and software we used. The ones that were the most useful were:
GIMP - available at gimp.org - is an open-source alternative to Adobe PhotoShop or Corel PaintShopPro, and is useful for editing photos and graphics, such as the surfaces of 3-D objects and clothing.
Avimator - available at avimator.com - for the gestures to animate your avatar. This allowed us to hold microphones up to our mouth to speak, hold a pointing stick to focus attention on specific things, or to drink coffee afterwards.
FRAPS - available at fraps.com - to capture video and screen shots. The free version is limited, so our designated "camera crew" purchased the full-price version, and worked very well.
I hope everyone enjoyed the French Open in Second Life! Here are some upcoming events:
Rational Software Development Conference comes to Second Life
As part of its commitment to the developer community, IBM is broadening the experience for conference visitors and avatars visiting IBM CODESTATION, in the virtual world of Second Life. During RSDC this year, visitors can view the General Sessions, catch Rational product demonstrations, interact with Rational experts, and learn about the first CODESTATION "Coder's Challenge" kicking off in July.
For Rational Software Development Conference (RSDC) information and registration, running June 10-14:here
Virtual Technical Briefing in Second Life: Web 2.0
Join IBM developerWorks in Second Life for a virtual Web 2.0 Briefing on June 21, 2007 at 12:30 pm EDT/ 9:30 am PDT. During this briefing from IBM developerWorks you'll see presentations on Web 2.0 technologies, a flash demo of associated hot technologies and have a chance to have your questions answered by IBM experts.
In the last two years Web 2.0 has created one of the most remarkable growth surges in Web application history. The transition of consumer Web sites from isolated information silos to sources of shared content and functionality, make the Web a true computing platform serving web applications to end-users. Now it's time to take the lessons learned from that success and see how it can bring value to you and your business.
Based on our success for our April 26 event, we decided to have the next event in September. More details to follow,but we plan to have it open to customers, analysts and business partners. If you are interested in participating, now is a good time to get your avatar in second life up and running. If you need "System Storage", "IBM Business Partner" logo clothing for your avatar, send me a note.
Use more efficient disk media, such as high-capacity SATA disk drives
Both are great recommendations, but why limit yourself to what EMC offers? Your x86-based machines are only a subset of your servers,and disk is only a subset of your storage. IBM takes a more holistic approach, looking at the entire data center.
VMware is a great product, and IBM is its top reseller. But in addition to VMware, there are other solutions for the x86-based servers, like Xen and Microsoft Virtual Server. IBM's System p, System i, and System z product lines all support logical partitioning.
To compare the energy effectiveness of server virtualization, consider a metric that can apply across platforms. For example, for an e-mail server, consider watts per mailbox. If you have, say, 15,000 users, you can calculate how many watts you are consuming to manage their mailboxes on your current environment, and compare that with running them on VMware, or logical partitions on other servers. Some people find it surprising that it is often more cost-effective, and power-efficient, to run workloads on mainframe logical partitions (LPARs) than a stack of x86 servers running VMware.
More efficient Media
SATA and FATA disks support higher capacities, and run at slower RPM speeds, thus using fewer watts per terabyte.A terabyte stored on 73GB high-speed 15K RPM drives consumes more watts than the same terabyte stored using 500GB SATA.Chuck correctly identifies that tape is more power-efficient than disk, but then argues that paper is more power-efficient than tape. But paper is not necessarily more efficient than tape.
ESG analyst Steve Duplessie divides up data betweenDynamic vs. Persistent. The best place to put dynamic data is on disk, and here is where evaluation of FC/SAS versus SATA/FATA comes into play.Persistent data, on the other hand, can be stored on paper, microfiche, optical or tape media. All of these shelf-resident media consume no electricity, nor generate any heat that would require additional cooling.
A study by scientists at the Lawrence Berkeley National Laboratory titled High-Tech Means High-Efficiency: The Business Case for Energy Management in High-Tech Industries indicates thatData centers consume 15 to 100 times more energy per square foot than traditional office space. Storing persistent data in traditional office space can save a huge amount of energy. Steve Duplessie feels the ratio of dynamic to persistent data is 1:10 today, but is likely to grow to 1:100 in the near future, raising the demand for energy-efficient storage of persistent data ever more important to our environment.
Data centers consume nearly 5000 Megawatts in the USA alone, 14000 Megawatts worldwide. To put that in perspective, the country of Hungary I was in last week can generate up to 8000 Megawatts for the entire country (and they were using 7400 Megawatts last week as a result of their current heat wave, causing them grave concern).
Back in the 1990's, one of the insurance companies IBM worked with kept data on paper in manila folders, and armiesof young adults in roller skates were dispatched throughout the large warehouses of shelves to get the appropriate folder in response to customer service inquiries. Digitizing this paper into electronic format greatly reduced the need for this amount of warehouse space, as well as improved the time to retrieve the data.
A typical file storage box (12 inch x 12 inch x 18 inch) containing typed pages single-spaced, double-sided, 12 point font could hold perhaps 100MB. The same box could hold a hundred or more LTO or 3592 tape cartridges, each storing hundreds of GB of information. That's a million-to-one improvement of space-efficiency, and from a watts-per-TB basis, translates to substantial improvement in standard office air conditioning and lighting conditions.

Alan Lepofsky posts about The Value Of Social Networking which points to this same presentation about Web 2.0 concepts and ideas.He also points to this article in the Wall Street Journal titledPlaying Well With Others about IBM and their leadership in Web 2.0 technologies, such as those from our Lotus group.
Some quotes from the WSJ article I found interesting:
Some 26,000 IBM workers have registered blogs on the company's internal computer network where they opine on technology and their work.
Social networking is especially important for the 42% of IBM employees who regularly work from their homes or client locations rather than IBM facilities.
At most companies, public-relations managers and the human-resources department tightly control all electronic communications except for email and instant messaging. ... Not at IBM.
"Any employee can have a blog, a wiki or a podcast,..."
IBM owns more than 50 "islands" in Second Life and often uses them for lectures and group discussions.
Two years ago, IBM started Wiki Central to manage wikis for IBM groups. It now has more than 20,000 wikis online with more than 100,000 users.
Interesting in learning more about Web 2.0? The last page of the deck above has a good set of links and resources, for example, here are 23 Things to know about Web 2.0 to get you started.
Avi Bar-Zeeb of RealityPrime has an interesting post aboutHow Google Earth [really] Works.Normally, people who are very knowledgeable in a topic have a hard time describing concepts in basic terms. Avi was one of the co-founders of Keyhole, the company that built the predecessor for Google Earth, and also worked with Linden Lab for its 3D rendering it its virtual world, so he certainly knows what he is talking about. While he sometimes drops down into techno-talk about patents, the post overall is a good read.
It is perhaps human nature to be curious on how things are put together and how they function, leading to the popularity of web sites like www.howstuffworks.com that cover a wide range of topics.
Many things can be used without understanding their internal inner workings. You can put on a pair of blue jeans without knowing how the cotton was made into denim fabric; lace up your favorite pair of running shoes without understanding the chemical make-up of the plastic that cushions your feet; or drink a glass of beer after your five mile run without knowing how alcohol is processed by your liver.
For technology, however, some people insist they need to know how it works in order for them to get the most use of it. When shopping for a car, for example, a guy might look under the hood, and ask questions about how the engine works, while his wife sits inside the vehicle, counting cup holders and making sure the radio has all the right buttons.
Not all technology suffers from need-to-know-itis. For example, the Apple iPod music player and the Canon PowerShot digital camera, are both just disk systems that read and write data, with knobs and dials on one end, and ports for connectivity on the other. Everyone just asks how to use their controls, and might read the manual to understand how to connect the cables. Few people who use these devices ask how they work before they buy them.
Other disk systems, the kind designed for data centers for the medium and large enterprise, apparently aren't there yet. Storage admins who might happily own both an iPod player and a PowerShot camera, insist they need to know how the technologies inside various storage offerings work. Is this just curiosity talking? Or are there some tasks like configuration, tuning, and support that just can't be done without this knowledge? Does knowing the inner workings somehow make the job more enjoyable, easier, or performed with less stress?
I'm curious what you think, send me a comment on this.
