The Harvard Extension School is running a course focused on virtual law with a Second Life component. Rebecca Nesson (’Rebecca Berkman’ in Second Life) is teaching the class. The lectures, which look fascinating, are available to at-large participants on Berkman Island [SLURL: http://slurl.com/secondlife/Berkman/113/70/24].
You can attend the lectures in Second Life on Monday evenings from 8:00-10:00pm EST (5:00-7:00pm SL time). Videos of past lectures are linked on the course’s web site, where you can also find the syllabus, a wiki, and more.
The US version of The Office (which does an excellent job of being almost as funny as the BBC version) is no stranger to life online. It’s fun to spot Kevin, Meredith, Creed, Roy, Pam all on MySpace, and Dwight has a blog. This week they dipped into Second Life. The very same week as CSI:NY; It’s all getting very mainstream.
Of course, the Office’s treatment of SL was as tongue-in-cheek as you’d expect…
Dwight:“Second Life is not a game. It is a Multi User Virtual Environment. It doesn’t have points or scores or winners or losers.”
Jim:“Oh, it has losers.”
Steve Nelson at Clear Ink, the team behind bringing the office into SL for the episode, has [written about the project] and carefully lists the locations and clothing used.
I watched this episode and loved how they were able to blend it in seamlessly without looking out of placeor awkward reference.
Cisco Systems Inc. has been staging virtual meetings between developers and channel partners in Second Life for more than a year, but this invitation was a first for me. So a presentation announcing the winners of a networking technology innovation contest -- inside a Second Life simulation -- seemed like the place to be.
I'm probably an SL noob (for newbie) by most standards, but I've spent enough time there to know most of the ways to move and how to search out islands and events.
In all, I would say the Cisco event sparked my interest in the SL virtual meeting format, but my attention was focused more on making things in SL work smoothly than on the material presented.
I've had some interesting conversations with event-coordinators looking for advice on setting up events in Second Life, so I suspect that is a good sign that this is still growing momentum.
Well, we had another successful event in Second Life today.
Unlike our April 26 launch of our System Storage products for IBM Business Partners only, this time we decided this time to make it as a "Meet the Storage Experts" Q&A Panel format, and open up registration to everyone. Thesubject matter experts sat at the front of the room on four stools. We had six rows of chairs arrangedsemi-circularly.
Shown above, from left to right, are the avatars of our four experts:
IBM System Storage N series, focusing on recent N3000 disk system announcements
Harold Pike (holding the microphone while speaking)
IBM System Storage DS3000 and DS4000 series, focusing on recent DS3000 disk system announcements
IBM System Storage TS series, focusing on recent TS2230, TS3400 and TS7700 tape system announcements
IBM storage networking, focusing on recent IBM SAN256B director blade announcements
While Eric was a veteran Second Lifer, having presented at our April event, the other three were trainedon how to raise their hand, speak into the microphone, sit on the stool, and so on. I want to thank allof our experts for putting in this effort!
The event was produced by Katrina H Smith. She did a great job, and made sure we were on top ofall the issues and tasks required to get the job done. Running a Second Life event is every bit ashard as running a real face-to-face event. We had several meetings to discuss venue details, placementof chairs, placement of product demos, audio/video recording, wall decorations, tee-shirt and coffee mug design, logistics, and so on.
I acted as moderator/emcee for the event. That is my back in the picture above. The process wassimple, modeled after the "Birds of a Feather" sessions at events like SHARE and the IBMStorage and Storage Networking Symposium. We threw out a list of topics the experts would cover,and people in the audience would "raise their left hand". I, as the moderator, would then walkover to each person, and hold out the microphone for them to ask the question. I would then repeat the question and ask the appropriate expert to provide an answer. We defined gestures onhow to "raise hand" and "put hand down" that we gave to each registered participant.
We had four dedicated "camera-avatars" in world to capture both video and screenshots.Our video editors are now working to edit "highlight videos" that we can use at future events, for training materials, and for our internal "BlueTube" online video system.
The room was filled with examples of each of our products, made into 3D objects that were dimensionallycorrect, and "textured" with photographs of the actual products. If you click on an object, you get a "notecard" that provided more information. Special thanks to Scott Bissmeyer for making all of theseobjects for us.
We made posters of each expert and placed them in all four corners of the room. On the bottom of each coffee mug was a picture of each of the experts, and if you walked under each of the posters, you were"dispensed" a coffee mug matching the expert shown in the poster.Participants could "Collect all Four!" When you bring the coffee mug up to takea sip, the picture on the bottom of the mug is exposed for all to see.And as a final give-away to the audience, we made a variety of event tee-shirts and polo-shirts.
At the end of the session, we asked everyone to click on the "Survey" kiosk near the exit door. We askedsix simple questions using SurveyMonkey.com that took only a fewminutes to process. We found asking questions immediately at the end of the event was the best way tocapture this feedback.
From a "Green" perspective, we had people registered from the following countries: US, India, Mexico,Australia, United Kingdom, Brazil, Germany, Argentina, Chile, China, Canada, and Venezuela. Second Lifeallows all these people who probably could not travel, or could not afford the time and expense to travel,to participate in a simulated face-to-face meeting without energy consumption of traditional travel methods.
More importantly, we got several leads for business. People often ask "Yes, but is there any businessassociated with this?" This time, there was, based on the answers to the questions, several avatars asked for a real sales call to follow-up on the products and offerings they were discussed.
With such a great success, we have already scheduled our next Second Life event, November 8. Mark your calendars! I'll postmore details on the registration process of the November event when available.
Registration for the "Meet the Storage Experts" event in Second Life will close this week fornext week's September 20 event. All IBMers, clients and IBM Business Partners are welcome to attend. We will focus this time on DS3000 and N series disk systems, tape systems,and IBM storage networking gear.
If you miss this one, we plan to have another one in November!
I can't believe I have been blogging for a year now!
I have Jennifer Jones from IBM to thank for getting this started. She was my predecessor in the job I have now, and she was moving on to bigger and better things, and during the transition for me to take over, she suggested that we start a blog, podcast, or similar. While there are many blogs and podcasts inside the firewall of IBM, I wanted something to be accessible to all of our IBM sales team, IBM Business Partners, existing and prospective clients, and to enable comments, to enable two-waycommunication. Podcasts are very one-way, so we chose a blog instead.Getting it set up took a while, convincing our own management that this was worthwhile, and dealing with our legal department on the IBM blogging guidelines of what we can and cannot write about, we finally got it going last year, launching September 1, just in time for our 50 years of disk systems innovation campaign.
It has been a wild ride, a great learning experience, and has proven quite fulfilling for job satisfaction. Here are some observations and lessons I have learned along the way.
Roller is the open source blog server that drives Sun Microsystem's blogs.sun.com employee blogging site, IBM DeveloperWorks blogs that this blog exists on, thousands of internal blogs at IBM Blog Central, the JRoller Java community site, and hundreds of others world-wide.Whereas there might be fancier blog systems elsewhere that I could have chosen, hosting my blog with IBM Developerworksseemed like a good choice. I can access from any web-browser capable machine, and enter my blog posts in nativeHTML, that I develop in the tool itself, or offline with a standard basic text editor like Microsoft Notepad that I can then cut-and-paste back in.
One lesson I learned the hard way was that Roller generates the Permalink URL for each blog post based on the first five words of the title. For that reason, it is important to chose an appropriate and unique title, avoiding the use of punctuation, quotation marks, or pharmaceutical "enhancement products" that might get rejected by SPAM filters.Once chosen, you can't change the title afterwards as it won't match the Permalink anymore.My blog post "Aperi is (enhancement product) for SMI-S" caused no end of grief to our Press Release team.
Writing blog posts in native HTML is not as hard as it sounds. I am limited to hosting a maximum of 24MB of files, and they can only be jpg, jpeg, gif, png, mp3, pdf or ppt format.So, wherever possible, I point to other websites for content.For those new to blogging, I recommendThe Barebones Guide to HTML.
Roller also generates for me a spreadsheet of all my page views for the week. Tracking blog traffic closely is as crazyas checking your company's stock price every day. These "web-stat" e-mails get filed directly into my Bacn folder on Lotus Notes.
In my earlyadvice to bloggers, I mentioned my choice of Bloglines as my RSS feed reader. When I subscribe to a new blog, I specify Full entries, not Partial,which allows me to scan it quickly, but filters out many of the non-text content like videos. It also allowed meto see what my own blog posts looked like from within a reader, so that I can write them appropriately.
I find if valuable to read other blogs, including those written by employees of our toughest competitors. Evenif you don't blog yourself, following blogs can be extremely valuable. Be careful what you leave as comments onother blogs, they may come back to haunt you later.
Currently, I track 55 blogs, some about storage,marketing, Web 2.0 issues, Second Life, Linux, or other areas of interest. I prefer blogs that make only 1-5 postsper week, so blogs like LifeHacker and LifeRemix are off my Bloglines list, but are excellent resourceswhen I am searching for something specific. If you think 55 is a lot of blogs, consider Timothy Ferriss' post onHow RobertScoble reads 622 RSS feeds each morning.
I have quite an international readership, so I have to be careful using American idioms and pop cultural references.For example, in my blog post IBM acquires Softek, I mentioned "shotgun weddings" and had various responses asking what exactly did that mean,all from readers outside the USA. I've learned that sometimes you need to link them to an American Slang dictionary,or Wikipedia encyclopedia entry to explain these terms and phrases.
Technoraticurrently tracks over 100 million blogs and over 250 million pieces of tagged social media. Getting my blogtracked had some issues. You have to join, thenpost a "claim"on your own blog. My mistake was having a case-sensitive URL with a mix of upper and lower case letters, but Technorati prefers all lower case. IBM worked with Technorati to get this resolved.
Del.icio.us is a social bookmarking website -- the primary use is to store your bookmarks online, which allows you to access the same bookmarks from any computer and add bookmarks from anywhere, too. On del.icio.us, you can use tags to organize and remember your bookmarks, which is a much more flexible system than folders.
I use Firefox, Safari, Dillo and Internet Explorer web browsers, so it is nice that I have access to allmy bookmarks in the same consistent manner. When I see content on a website that I might like to reference laterin a blog, I tag it with del.icio.us so that I can get to it later.
Fellow GTD-ers will quickly recognize this acronym, but for the rest of you, it refers to David Allen's book "Getting Things Done®".This is a great book! I learned about it reading other people's blogs, and found it incrediblyuseful helping me organize my time.There are various online tools available to help employ this method. I use Lotus Connections Activitiesfor group projects with co-workers at IBM, and BackPack for projects withmy friends outside of work.
The success of YouTube encouraged IBM to launch IBM TV, a portal for IBM's video and multimedia assets and make it easier for IBM employees, customers, partners and prospects to access and view IBM multimedia. The plan is to have eight anchor episodes per year, professionally hosted by TV personality, Joe Washington, and point to related offers and other resources for viewers to learn more.
Blogging also introduced me to Second Life. I asked around if anyone else within IBM was using Second Life, anddiscovered quite a few. I got invited to join our internal Eightbar group, and participated in various events, including an IBM Holidayparty that I discussed in my blog post"Building a Snowman in Second Life".
In April, we had a launch of our newest products in Second Life, and we plan to have two more Second Life events,September 20 and another in November, staged as "Meet the Experts" question and answer panels.
I wrap up with Facebook. Actually, whereas most of my Web 2.0 efforts have been work-related, I have quite a few friends and family who follow my blog. Several were inspired to start their own blogs, such asPassages from Pamand Barry Whyte on Storage Virtualization. Bridging the gap is Facebook, something I can use to keep tabs on my friends, as well as my storage industry-related contacts.
Wow, that's quite a lot in one year. Well, I am done with my meetings down here in Sao Paulo, Brazil. My colleauges and I are returning tonight to enjoy the long Labor Day weekend.
Registration is now open for our next "Meet the Storage Experts" event in Second Life. All IBMers, clients and IBM Business Partners are welcome to attend. We will focus this time on DS3000 and N series disk systems, tape systems,and IBM storage networking gear.
Philip Rosedale, chief executive of Linden Labs, which produced the Second Life virtual reality environment, said Second Life and Facebook are popular because they give people a new environment to interact in that they are comfortable with.
Of course I have blogged for months now on my involvement in Second Life, and how IBM is investing in this platform for business purposes. Recently, IBM made news for publishing its Code of Conduct,and set of guidelines on how you run your avatar in virtual worlds, including Second Life. IBM recognizesthe business potential of virtual worlds, and has formed the "3D Internet" group exploring the possibilities.Over 5000 IBM employees now use Second Life on a regular basis.
I was surprised to learn that there were over 23,000 IBMers already on Facebook. I used to be on LinkedIn,but found FaceBook to have more IBMers and have made the switch. Recently, we were told that these 23,000 IBMers spend 19 minutes, on average, per day visiting Facebook pages. Nobody askedme how much time I spend every day on FaceBook, but with over 350,000 employees in the company,I am sure some have ways to track the lives of others.
Both of these count as adding more "FUN" into the workplace, which everyone should strive for. It is also good to know that the skills you developusing Second Life or FaceBook can carry over to your next job role or your next employer.The number-one question I get from new colleagues when I mention either these exciting new ways to communicate and collaborate is: "But how is this related to business?"
Second Life is obvious, a new innovative way to hold meetings with colleagues, Business Partners and clients isgoing to have business value. Meetings in Second Life help you focus on what is being discussed, versus a plaintelephone call where your eyes may wander to other things in your view. Of course nothing beatsthe effectiveness of face-to-face meetings, but Second Life offers a more energy-efficient alternative than traveling to other cities or countries.
There are a lot of exciting conferences and events coming up soon.
SHARE will be in San Diego, August 12-17. Held twice a year, I attended SHARE for 10 years back when I was lead architect for DFSMS,and then later the focal point for storage support on the Linux for System z platform.I won't be there this time around, but am glad to see that it is still thriving.
IBM Storage and Storage Networking Symposium
IBM Storage and Storage Networking Symposium will be in Las Vegas, August 19-24.This is a great conference that is focused entirelyon the products and solutions I deal with the most. I attended nearly every one since they startedthis back in the 1990s, and am glad that I will be there this year, making several presentations.If you plan to attend this and want to meet up, drop me a note.
VMworld will be held in San Francisco, September 11-13.IBM is a top reseller of VMware software, and is proud to be a Platinum Sponsor for this event. Lookfor the panel discussion on "Storage Virtualization" which I am sure will include SAN Volume Controller.
Meet the Storage Experts
Based on our successful product launch in Second Life back in April, we are now holding meetingsevery quarter to discuss various IBM System Storage topics. The next one will be September 20 onone of the IBM islands in Second Life. For those without travel budgets to go anywhere, the advantageto our "Second Life" events is that no travel is required, it can be done from the comfort of workor home office location.
I will post updates on how to register for this event as soon as I know them.
Virtual Worlds Fall 2007 onOctober 10-11, 2007 at the San Jose Convention Center. Sandy Kearney, IBM GlobalDirector of IBM 3D Internet and Virtual Business, will be the keynote speaker.This will include discussion of Second Life.
I am sure there are others, but these are the ones that I am aware of IBM's involvement.I'll be in Chicago next week, meeting with Sales Reps and Business Partners.
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.
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.
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.
