It's official. Last week,while I was talking about Fundamental Changes
needed to make your IT environmentmore energy-efficient, IBM announced its "Big Green Linux" initiative at LinuxWorld conference.
You can read the IBM Press Release, or the commentary onDaniWeb,ZDnet, orInfoWorld.
IT managers looking to reduce their energy consumption are probably closely watching XenSource and VMware. CRN feels that a war is imminent between these two. Eweek recognizes thisbattle is bad news for Linux virtualization on x86,and that Oracle is losing patienceon their inability to work together. Simon Crosby, CTO of XenSource, compares performance between the two platforms, and feelsthat XenSource should get its rightful piece of the pie.
There is a ray of hope. Charles Babcock in Information Week explains thatpeace has been established on at least one front, XenSource and VMware are working together to improve virtualization in the Linux kernel.
Despite this, or perhaps because of this, over 30 percent of IBM's Linux server revenue is onnon-x86 platforms, avoiding the XenSource vs. VMware decision altogether. Both System z (traditional mainframe servers) and System p (traditional UNIX servers) are able to run many Linux images in a fully virtualized manner, without VMware or XenSource.

The IBM Storage and Storage Networking Symposium continues ...
- DS8300 Benchmark for Global Mirror
Phil Allison of Fidelity National Information Services presented his success switching from competition over to IBM DS8300 disk systems for use with Global Mirror. They had usedPerformance Associates famous PAIO driver to help to the benchmarktesting. They ran the benchmars at 2x and 3x their current workloads to see how well the DS8000 performed,measuring IOPS, MB/sec, and millisecond response time (msec). They were very impressed with their results,staying below their target 0.8 msec for most of their runs.
For the Global Mirror, the did a performance "bake-off" between Ciena CN2000 versus Cisco 9216i. These areimplemented differently. Ciena uses a Layer-2 approach, encapsulating the Fibre Channel packets directlyto transport as SDH/SONET or Gigabit Ethernet (GigE), which required dedicated circuits between JacksonvilleFlorida and Little Rock, Arkansas. By contrast, Cisco uses a Layer-3 approach, encapsulating Fibre Channelpackets within an IP packet, which can leverage existing datacenter-to-datacenter backbone.
To add stress to the benchmarks, they used a "Network Impairment" emulator. These artificially inject errors,lose packets, and other signal loss conditions. Running both Cisco and Ciena under these tests help them decide which to purchase, but also enforced that idea that they made the right choice choosing IBM for theirremote distance mirroring solution.
- Comparison of Bare Machine Recovery Techniques
"Bare machine recovery" is the phrase used to restore a machine that has no operating system installed (or thewrong operating system). Dave Canan from IBM Advanced Technical Support did a great job reviewing the variousproducts and techniques available, and the pros and cons of each approach. The ones he covered were:
- Tivoli Storage Manager - install fresh Windows Operating System, TSM client, and then follow certain steps
- Automated System Recovery(ASR) - a new feature of Windows XP and Windows 2003 works with TSM client
- Symantec Ghost - formerly callled PowerQuest Drive Image, there are now two versions: Ghost Home Edition and Ghost Corporate Solution Suite
- Cristie Bare Machine Recovery(CBMR) - This is an IBM partner that provides both Linux and Windows PE versions. Cristie includes a license for Windows PE, so no need to use the alternative Bart PE method.
- SAN Volume Controller - Customer Experience
Bill Giles of Catholic Medical Center, a hospital in New Hampshire, presented his experienceswith IBM System Storage SAN Volume Controller. They have a mix of IBM System x, System p, andSystem i servers, as well as machines from HP, Sun, and Dell. For applications, they havePicture Archiving and Communicatiion System (PACS) for cardiology and radiology, HL7 Interface engine, Clinical Information System, TSM for backup, and Microsoft Exchange fore-mail.
They deployed SVC on AIX, Solaris, Windows 2000 and 2003. They were very delightedwith the results:
- Centralized Storage Provisioning
- Consolidating disparate storage into a universal platform
- Enables non-disruptive data migration
- Increased utilization of existing disk resources
- Improved disaster recovery with FlashCopy and Metro Mirror
- Birds of a Feather (BOF) sessions
We had two BOFs, one for storage attached to System z operating systems, and another for storage attached to Linux, UNIX and Windows systems. This distinctionmade sense when mainframes could only attach to CKD disks and ESCON/FICON tape,and distributed systems could only do FCP/SCSI, but these days, there are all kindsof convergence going on.
Linux on System z can now attach via FCP to LTO tape and SAN Volume Controller, allowing now a wide range of storage options for that platform. z/OS, z/VM, z/VSEand Linux on System z can all access IBM System Storage N series via NFS.
The format was traditional Q&A panel, we had experts at the front of the room,handling the questions and discussion topics brought up by the audience. I'll spareyou the individual questions and answers.

CNET staff writer Elinor Mills writes how some things in Web 2.0 have morphed, going from killer app to major Web platform
.Among the examples are Salesforce.com, Google, Second Life, and Facebook.
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.
I am still fairly new to Facebook, installing and trying out new apps. I found this article that explains12 Ways to Use Facebook Professionally. So far it serves me well as a replacement for LinkedIn,and provides my friends and family a quick answer to Where in the world is Tony Pearson?
What else can these and other Web platfoms do? I am still in the exploratory stages.
