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.
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.
I get a lot of suggestions for what to put on my blog.I realize that tweets are limited to 140 characters, so pointing to a video URL without muchexplanation or warning can be dangerous. An email can at least add appropriate warnings,such NSFW (Not Safe For Work) or "sorry if this offends you". The only warning I got fora video posted to YouTube by "StorageNetworkDud" was this short email:
"Sorry about the language they have used in some translations, but not sure who put this. It was on twitter."
Fortunately, I have my browser set up not to automatically play YouTube videos. The titlehelped warn me of the content, which turned out to be a [fan-subbed] scene from a World War II movie with brown-shirted tyrannical leader of an evil empire talking to his top generals. He dismisses all but threewith "Hollis, Burke, and Twomey stay in here" followed by a lengthy recap of EMC's recent troublesin the marketplace. At least in the video, the fuhrer correctly follows Tim Sander's advice:"if you have to tell someone bad news, say it in person."
While I understand that many people don't like EMC, the #3 storagevendor in the world, this type of "geek humor" hits a new low. The video was posted over amonth ago, but in light of the recent [shooting in Washington DC], I felt it was just notappropriate to post it here.
Readers, I appreciate all the suggestions, but give me some better warning next time!
Continuing this week's theme on Storage Area Networks, today I thought I would talkabout the various terms we use for our equipment.
One area of confusion are the adjectives "entry-level", "midrange" and "enterprise-class".What do these mean? Well, as in the case of disk and tape, these three are all relative terms that are a combination of "small, medium, large" as well as "good, better, best".
Entry-level switches are typically only a maximum of 8-16 ports.Ports can connect the switch to a server, a storage device, or another switch.These are sometimes called "edge" switches, as they might be found in the mostremote sections of an office campus, remote branches, or other isolated areasoutside the primary data center.
Midrange switches typically have a maximum of 32-64 ports.More ports on a single switch means fewer switches (and fewer cables) to manage.
These are called "directors" to distinguish them from entry-level and midrange offerings.Directors have a maximum of 140-528 ports, and because so many devices or switches can beconnected to them, they need to be extremely reliable. Directors are designed for 24x7operation, with the ability to make most upgrades and configuration changes while the boxis running (often referred to as "non-disruptive upgrades"). Availability is typically better than "five nines", or 99.999 percent, which means that the box will be up 99.999 percent of the time, or conversely, will be down lessthan 5 minutes per year.
If you are asking yourself "which size is right for my company?" or "is my company big enoughfor a director?" you are asking the wrong questions! Instead, determine a SAN configurationthat meets your workload, and then decide the components for that design.
McData coined a phrase called "core/edge" design that is considered today as "Best Practice" throughout the industry.A good write-up can be found here at SearchStorage.com. Basically, you put your big beefy "core" directors in the center of the room, and then surround it with midrange switches, that then these connect to "edge" switches, that then connect to the servers and storage near them. As you grow, this design can easilyscale to grow with you.
So, if you need help implementing a SAN for the first time, or upgrading the one you have,call IBM, we can help!
Rich Bourdeau has written a nice article on InfoStor titled [Software as a Service (SaaS) meets Storage]. Last year, IBM acquired Arsenal Digital, and he mentions both in this article.It is interesting how this has evolved over the years.
Rent warehouse space for tapes
I remember when various companies offered remote storage for tapes. These would be temperature and humidity-controlledrooms, with access lists on who could bring tapes in, who could take tapes out, and so on. In the event of thedisaster, someone would collect the appropriate tapes and take them to a recovery site location.
Rent online/nearline storage from a Storage Service Provider (SSP)
SSPs rented storage space on disk, or provided automated tape libraries that could be written to. With tapes being ejected and stored in temperature/humidity-controlled vaults. Electronic vaulting eliminates a lot of theissues with cartridge handling and transportation, is more secure, and faster. Rented disk space, based on a Gigabytes-per-month rate, could be used for whatever the customer wanted. If these were for backups or archive,then the customer has to have their own software, to do their own processing at their own location, sending the data to the remote storage as appropriate, and manage their own administration.
Backup-as-a-Service and Archive-as-a-Service
We are now seeing the SaaS model applied to mundane and routine storage management tasks. New providers can offerthe software to send backups, the disk to write them to, and as needed the tape libraries and cartridges to rollover when the disk space is full. Disk capacity can be sized so that the most recent backups are on immediately accessible for fast recovery.
The same concept can be applied to archives. The key difference between a backup and an archive is that backups areversion-based. You might keep three versions of a backup, the most recent, and two older copies, in case something is wrong with the most recent copy, you can go back to older copies. This could be from undetected corruption of the data itself, or problems with the disk or tape media. An archive, on the other hand, is time-based. You want this data to be kept for a specific period of time, based on an event or fixed period of years.
Since BaaS and AaaS providers know what the data is, have some idea of the policies and usage patterns will be, can then optimize a storage solution that best meets service level agreements.
This week, I am in Las Vegas for [Edge 2016], IBM's Premiere IT Infrastructure conference of the year. Here is my recap of Day 3 Wednesday.
Become your own Storage Consultant
Gary Graham, IBM Field Technical Specialist for Storage, and Brian Pioreck, IBM Client Technical Specialist for Storage, co-presented this session. This session explained how to use IBM's 30-day free trial of IBM Spectrum Control Storage Insights, a cloud-based services offering.
(Note: 15 years ago, I was the chief architect of version 1 of what we now call IBM Spectrum Control. I am pleased to see how well this product has evolved over the years.)
Storage Insights provides a reporting-only subset of the popular IBM Spectrum Control Standard and Advanced editions. It reports on IBM storage devices, as well as any non-IBM devices that are virtualized behind IBM Spectrum Virtualize products like SAN Volume Controller (SVC), Storwize, and FlashSystem V9000.
If you are a storage administrator, consider trying this out for 30 days, get some immediate results. Since it is cloud-based, you only need a Windows, Linux or AIX system to install a "collector" on site. This collector sends data up to the Cloud at one of IBM SoftLayer facilities. The installation process takes only 30 minutes, and you can download the code from the Internet.
If you find Storage Insights valuable, helping you reclaim some unused space, or provide other insight that saves your company money, consider buying the service, for only 250 US Dollars per 50 TB monitored. If you want more than just monitoring and reporting, consider one of the on-premise solutions like IBM Spectrum Control Standard, or IBM Spectrum Control Advanced edition, which provide provisioning and configuration capabilities as well.
Enhance your Security posture with At-Rest Encryption using the latest IBM Spectrum Virtualize
All of the IBM Spectrum Virtualize products support Data-at-Rest Encryption. For direct-attached storage, the 12Gb SAS controller performs hardware-assisted encryption.
For SAN-attached storage via FCP, FCoE or iSCSI back-end devices, IBM uses the [AES-NI instruction set] that comes included in certain Intel CPU processors.
Last November 2015, [IBM acquired Cleversafe] for $1.3 Billion US dollars because Cleversafe has the brand name recognition as the #1 Object Storage vendor the past two years in a row (2014 and 2015). On July 1 of this year, the transformation was complete, and their flagship product was officially renamed to the IBM Cloud Object Storage System, which some abbreviate informally as IBM COS.
Since then, IBM has been busy integrating IBM COS into the rest of the storage portfolio. I explained how IBM COS can be used for all kinds of static-and-stable data, but not suited for frequently changed data, such as Virtual machines or Databases.
Object storage can be access via NFS or SMB NAS-protocols using a gateway product, like IBM Spectrum Scale, or those from third-party partners like Ctera, Avere, Nasuni or Panzura. It can also be used as an alternative to tape for backup copies, and is already supported by the major backup software like IBM Spectrum Protect, Commvault Simpana, or Veritas NetBackup.
A few years ago, I explained to a client that Converged and Hyperconverged were like a pendulum swinging back. Over the past few decades, we have gone from internal disk, to externally attached disk, to SAN and LAN networks.
Each time, we gained more flexibility, greater connectivity and longer distances. Then I explained that Converged and Hyperconverged is like going backwards, the pendulum swinging back to the days of internal and direct-attached storage. The analogy was a hit, and thus this session was born!
IBM offers multiple Converged Systems. IBM PureSystems, PureData, PurePower and PureApplication solutions offer racks of compute, storage and network gear. Last year, IBM collaborated with Cisco to create VersaStack, a converged system that combines Cisco's x86 blade servers and switches with IBM FlashSystem and Storwize products.
IBM also offers Hyperconverged solutions. IBM Spectrum Accelerate allows the compute, storage and network functions run on 3 to 15 VMware ESXi hosts to form a cluster. The cluster can then make iSCSI-based volumes available to other virtual machines running on these same hosts. The volumes can also be made available to servers outside the cluster, such as bare metal servers or other Hypervisors. This is available as software-only, or you can get pre-built system called the Supermicro Hyperconvergence Appliance.
IBM Spectrum Scale provides a clustered file system that allows the compute, storage and network functions to run on 3 to 16,000 machines. Formerly called General Parallel File System (GPFS), IBM Spectrum Scale has been around for over 18 years. Over 200 of the world's largest "Top 500" supercomputers run IBM Spectrum Scale today.
IBM Spectrum Virtualize and IBM Storwize Birds-of-a-Feather
Barry Whyte, fellow blogger and IBM Master Inventor, presented an overview of the latest features, and where IBM is headed in 2017 for the IBM Spectrum Virtualize family of products. Barry now works in Advanced Technical Skills for Storage Virtualization Asia/Pacific Region.
The group then moved to another room offering delicious food and drink, as Eric Stouffer, IBM Director, Storwize Offering Manager and Business Line Exec, presented the future areas that IBM is consider for this product family.
All of this was done under Non-Disclosure Agreements (NDA), preventing me from blogging any details. Back in 2003, Las Vegas started a marketing campaign ["What Happens in Vegas, Stays in Vegas"]. Coincidentally, this is the same year IBM introduced the IBM SAN Volume Controller, the first product in the IBM Spectrum Virtualize family.
This was a long day, but was pleased with the large audiences I had at my sessions.
Yesterday, I went to the Bodyworlds exhibition. Here the anatomy of real human cadavers are on display, in full detail, thanks to a process calledPlastination.This was a great way to present anatomy in a 3-D visual way that can be easily understood and appreciated.I was glad to see so many children were there, although I warn parents that some sections of the exhibit maybe a bit shocking. I heard people speaking French and German, and it was great that anyone can be fascinatedby the human body, without having to read or understand English.
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.
Well, it's the last day of the year, and I will be celebrating the new year soon.In the mean time, I leave you with an interesting triple combo related to information.
Nick Carr in his post [Cleaning the Slate] offers a list of articles he did not have time for in 2007.Of these, I enjoyed the 7-page keynote address[Information, Knowledge, Authority and Democracy] by Hunter R. Rawlings III.He talks about the importance of recorded knowledge, including discussions by the US founding fathers Thomas Jefferson and James Madison, and how information is an essential part of democracy.Here's a brief excerpt:
Following the burning of the Capitol in 1815,President James Madison restored the Library of Congress by purchasing ThomasJefferson’s library for the nation. It was Jefferson’s unique classification scheme that thefirst full-time Librarian of Congress, appointed by Madison, used in reorganizing theLibrary. The United States, embodied in the Congress, was to have the best library inthe world because knowledge was necessary to its fundamental purpose, the creationand protection of liberty.
James Madison believed, in other words, that he lived in a “knowledge age.” In ourmyopic way, we like to think that we invented the knowledge age sometime late in the20th century. We did not. Madison and his contemporaries had complete faith andconfidence in the necessity of what they called “useful knowledge,” which, of course,privileged many things we no longer consider useful, such as the ability to read Latinand Greek and to understand the lessons of ancient history.
...by employing collaborative filtering, you use other people’s time to weed out the things that would waste yours. In fact, Del.icio.us and Stumble Upon polls your friends and people with similar interests for the most crucial sources of information and anything else you might have accident skipped over. If The Wisdom of Crowds has taught us anything, it is that a large group of people is drastically more efficient than you’ll ever be on your own.
Unless you enjoy grinding yourself to the bone, use this principle—whether you call it “crowdsourcing” or otherwise—to stop drinking from the information fire hose. It’s not more information, it’s better information, that distinguishes the real winners in business and life.
Finally, Galacticast presents [A Copyright Carol],a humorous 5-minute parody video on what might happen in the future as a result of lawslike the Canadian Digital Millennium Copyright Act[DMCA].
Today, IBM announced its latest [BladeCenter S] with integratedredundant SAN fabric and disk storage inside the chassis. The tag line is "Data Center Capability, without the Data Center!"
I've gotten a few calls on this today, so I thought it would be good to blog about. To understand what is new,you need to understand what we had in other BladeCenter chassis. In those other chassis, there were up to 14 bladeservers on the front, and switch modules for FCP and Ethernet on the back. The entire chassis was rack-mountedto be connected to external devices.
The BladeCenter S was announced a year ago.With the new "BladeCenter S" chassis, the storage can be included inside the chassis, as well as connecting tothe outside world. It is designed to be stand-alone, rather than rack-mounted, plugs into a standard 100v-240v office power outlet,and includes a dust filter in caseyou keep it close to the floor, under your desk for example.
Click graphic at left for 4-minute video introduction.
(Here's also a more detailed[7-minute video] with fellow IBM colleague Alex Yost.)
Here's what you can get with the BladeCenter S:
Up to six(6) server blades that can do the work of 25-45 traditional servers.
Up to two(2) storage blades, each can have six(6) SAS or SATA disk drive modules (DDMs)
Up to four(4) switch modules, with a variety to choose from
Shared KVM, DVD/CD burner, and USB port. You can designate which blade has access to these, useful forinstalling software, attaching external devices, and so on.
The blades use either Intel, AMD or POWER processors, so you can run Windows, Linux, AIX, and [IBM i] (the newname for i5/OS V6R1).
Back 20 years ago, I worked with people with System/36 and System/38 systems. They loved it. Everything inone package. This grew into the AS/400 server. Having everything in one package was such an advantage thatIBM extended this to include a few "x86 blades" to run Windows applications but share the storage and networkresources.
Now IBM has taken this one step further. The older models assumed the majority of applications run underIBM's OS/400 or i5/OS operating system, but this new BladeCenter S does not make that assumption. You canmix and match different blade servers as needed, and run the operating systems you need.
This is an ideal packaging for Small and Medium sized Business (SMB), remote branch offices, and retail stores.In fact, more than 4,000 retail stores plan to run their operations using BladeCenter S this holiday season! For moreon this announcement, see the [IBM Press Release].
