It's been a while since I've talked about [Second Life
The latest post on eightbar[Spimes, Motes and Data centers]discusses IBM's use of virtual world technology to analyze data centers in three dimensions.New World Note asks[What's The Point Of 3D Data Centers?]One would think that a simple monitoring tool based on a two-dimensional floor plan would be enough to evaluate a data center.
Enter Michael Osias, IBM (a.k.a Illuminous Beltran in Second Life). Some of the leading news sites havebegun to notice some 3D data centers that he has helped pioneer. UgoTrade writes up an article aboutMichael and the media attention in [The Wizard of IBM's 3DData Centers].
Of course, in presenting these "Real Life/Second Life" (RL/SL) interactive technologies, IBM is sometimes the target of ridicule. Why? Because IBM is 10 years ahead of everyone else. So, are there aspects of a data center where 3D interfaces makes sense? I think there is.
- Topology Viewer
IBM TotalStorage Productivity Center has an awesome "topology viewer" that shows what servers are connectedto which switches, to which disk systems and tape libraries. This is all done in a 2D diagram, generated dynamicallywith data discovered through open standard interfaces, similar to what you might draw manually with toolslike Visio. Imagine, however, howmore powerful if it were a 3D viewer, with virtual equipment mapped to the physical location of each pieceof hardware on the data center floor, including the position on the rack and location on the data center floor.
- Temperature Flow
Designing computer room air conditioning (CRAC) systems is actually a three dimensional problem. Cold air isfed underneath the raised floor, comes up through strategically placed "vent" tiles, taken in the front ofeach rack. Hot air comes out the back of each rack, and hopefully finds ceiling duct intake to get cooled again.The temperature six inches off the floor is different than the temperature six feet off the floor, and 3Dmonitor tools could be helpful in identifying "hot spots" that need attention. In this case "spimes" representsensors in the 3D virtual world, able to report back information to help diagnose problems or monitor events.
- Server consolidation
After many people left the mainframe in favor of running a single application per distributed server, the pendulumhas finally swung back. Companies are discovering the many benefits of changing this behavior. "Re-centralization" is the task at hand. Thanks to virtualization of servers, networks and storage, sharing common resources canonce again claim the benefits of economies of scale. In many cases, servers work together in collective unitsfor specific applications that might benefit better if consolidated together onto the same equipment.
IBM's "New Enterprise Data Center" vision recognizes that people will need to focus on the management aspectsof their IT infrastructure, and 3D virtual world technologies might be an effective way to getthe job done.

Continuing this week in Los Angeles, I went to some interesting sessions today at theSystems Technical Conference (STC08).
- System Storage Productivity Center (SSPC) - Install and Configuration
Dominic Pruitt, an IBM IT specialist in our Advanced Technical Support team, presented SSPC and howto install and configure it. For those confused between the difference of TotalStorage ProductivityCenter and System Storage Productivity Center, the former is pure software that you install on aWindows or Linux server, and the latter is an IBM server, pre-installed with Windows 2003, TotalStorageProductivity Center software, TPCTOOL command line interface, DB2 Universal Database, the DS8000 Element Manager, SVC GUI and CIMOM, and [PuTTY] rLogin/SSH/Telnet terminal application software.
SSPC speeds up the deployment of TotalStorage Productivity Center. The[SSPC Planning Worksheet] captures all of the pieces of information you need to activate the machine. On March 8,IBM simplified the [procedure to change the SSPC host name].
Of course, the problem with having a server pre-installed with a lot of software is that there is alwayssomeone that wants to customize it further. For those who just want to manage their DS8000 disk systems,for example, it is possible to uninstall the SVC GUI, CIMOM and PuTTY, and re-install them later when youchange your mind. As a general rule, it is not wise to mix CIMOMs on the same machine, as it might causeconflicts with TCP ports or Java level requirements, so if you want a different CIMOM than SVC, uninstallthe SVC CIMOM first. For those who have SVC, the SSPC replaces the SVC Master Console, so you can safelyturn off the SVC CIMOM on your existing SVC Master Consoles.
The base level is TotalStorage Productivity Center "Basic Edition", but you can upgrade the Productivity Centerfor Disk, Data and Fabric components with license keys. You can also run Productivity Center for Replication,but IBM recommends adding processor and memory to do this (IBM offers this as an orderable option).Whether you have the TotalStorage software or SSPC hardware, Productivity Center has a cool role-to-groups mapping feature.You can create user groups, either on the Windows server, the Active Directory, or other LDAP, and then map which roles should be assigned to users in each group.
Since Productivity Center manages a variety of different disk systems, it has made anattempt to standardize some terminology. The term "storage pool" refers to an extentpool on the DS8000, or a managed disk group on the SAN Volume Controller. Since the DS8000 can support both mainframe CKD volumes and LUNs for distributed systems, theterm "volume" refers to a CKD volume or LUN, and "disk" refers to the hard disk drive (HDD).
To help people learn Productivity Center, IBM offers single-day "remote workshops"that use Windows Remote Desktop to allow participants to install, customize and usethe software with no travel required.
- IBM Integrated Approach to Archiving
Dan Marshall, IBM global program manager for storage and data services on our Global Technology Services team, presented IBM's corporate-wide integration to support archive across systems, software and services.One attendee asked me why I was there, given that "archive" is one of my areas of subject matter expertise that I present often at the Tucson Executive Briefing Center. I find it useful to watch others present the material, even material that I helped to develop, to see a different slant or spin on each talking point.
Archive is one area that brings all parts of IBM together: systems, software and services.Dan provided a look at archive from the services angle, providing an objective unbiasedview of the different software and systems available to solve specific challenges.
- Encryption Key Manager (EKM) Design and Implementation
Jeff Ziehm, IBM tape technical sales specialist, presented IBM's EKM software, how it works in a tape environment, and how to deploy it in various environments. Since IBM is allabout being open and non-proprietary, the EKM software runs on Java on a variety ofIBM and non-IBM operating systems. IBM offers "keytool" command line interface (CLI) for the LTO4 and TS1120 tape systems, and "iKeyMan" graphical user interface (GUI) for theTS1120. Since it runs on Java, IBM Business Partners and technical support personneloften just [download and install EKM]onto their own laptops to learn how to use it.
- Virtual Tape Update
We had three presenters at this one. First, Jeff Mulliken, formerly from Diligent and now a full IBM employee, presented the current ProtecTier softwarewith the HyperFactor technology, then Abbe Woodcock, IBM tape systems, compared Diligent with IBM's TS7520 and just-announced TS7530virtual tape libraries, and finally Randy Fleenor, IBM tape sales leader, presented IBM's strategy going forward in tape virtualization.
Let's start with Diligent. The ProtecTier software runs on any x86-64 server withat least four cores and the correct Emulex host bus adapter (HBA) cards. Using Red HatEnterprise Linux (RHEL) as a base, the ProtecTier software performs its deduplication entirely in-lineat an "ingest rate" of 400-450 MB/sec. This is all possible using 4GB memory-resident "dictionary table" that can map up to 1 PB of back end physical storage, which could represent as much as 25PB of "nominal" storage. Theserver is then point-to-point or SAN-attached to Fibre Channel disk systems.
As we learned yesterday from Toby Marek's session, there are four ways to performdeduplication:
- full-file comparisons. Store only one copy of identical files.
- fixed-chunk comparisons. Files are carved up into fixed-size chunks, and each chunkis compared or hashed to existing chunks to eliminate duplicates.
- variable-chunk comparisons. Variable-length chunks are hashed or diffed to eliminate duplicate data.
- content-aware comparisons. If you knew data was in Powerpoint format, for example,you could compare text, photos or charts against other existing Powerpoint files toeliminate duplicates.
IBM System Storage N series Advanced Single Instance Storage (A-SIS) uses fixed-chunkmethod, and Diligent uses variable-chunk comparisons. Diligent does this using "dataprofiling". For example, let's say most of my photographs are pictures of people, buildings, landscapes, flowers and IT equipment. When I back these up, the Diligentserver "profiles" each, and determines if any existing data have a similar profilethat might have at least 50 percent similar content. Diligent than reads in the data that is mostly likely similar, does a byte-for-byte ["diff" comparison], and creates variable-lengthchunks that are either identical or unique to sections of the existing data. Theunique data is compressed with LZH and written to disk, and the sequential series of pointer segments representing the ingested file is written in a separate section on disk.
That Diligent can represent profiles for 1PB of data in as little as 4GB memory-residentdictionary is incredible. By comparison, 10TB data would require 10 million entries on a content-aware solution, and 1.25 billion entries for one based on hash-codes.
Abbe Woodcock presented the TS7530 tape system that IBM announced on Tuesday. It has some advantages over the current Diligent offering:
- Hardware-based compression (TS7520 and Diligent use software-based compression)
- 1200 MB/sec (faster ingest rate than Diligent)
- 1.7PB of SATA disk (more disk capacity than Diligent)
- Support for i5/OS (Diligent's emulation of ATL P3000 with DLT7000 tapes not supported on IBM's POWER systems running i5/OS)
- Ability to attach a real tape library
- NDMP backup to tape
- iSCSI attachment
- tape "shredding" (virtual equivalent of degaussing a physical tape to erase all previously stored data)
Randy Fleenor wrapped up the session telling us IBM's strategy going forward with all of thevirtual tape systems technologies. Until then, IBM is working on "recipes" or "bundles", puttingDiligent software with specific models of IBM System x servers and IBM System Storage DS4000 disk systemsto avoid the "do-it-yourself" problems of its current software-only packaging.
- Understanding Web 2.0 and Digital Archive Workloads
I got to present this in the last time slot of the day, just before everyone headed off to the [Westin Bonaventure hotel] for our big fancy barbecue dinner. Like my previous sessionon IBM Strategy, this session was more oriented toward a sales audience, but both garnereda huge turn-out and were well-received by the technical attendees.
This session was requested because these new applications and workloads are what is driving IBM to acquire small start-ups like XIV, deploy Scale-Out File Services (SOFS), and develop the innovative iDataPlex server rack.
The session was fun because it was a mix of explanation of the characteristics ofWeb 2.0 services; my own experience as a blogger and user of Google Docs, FlickR, Second Life andTivo; and an exploration in how database and digital archives will impact thegrowth in computing and storage requirements.
I'll expand on some of these topics in later blog posts.

It seems like I just get out of one conference, and into another. This week I am at Pulse 2008, which combines the best of IBM Tivoli and Maximo into one conference.Like many conferences, this one starts on Sunday, and ends on Thursday.
We're at the Swan and Dolphin hotels at [Walt Disney World] in Orlando, Florida. I've been to several conferences in Orlando, but this is my first time at the Swanand Dolphin. (When I walked into the main lobby, I had a bout of "deja vu". IBM LotusSphere was here last year, and they had a complete replica made in SecondLife!)
If you haven't been to Walt Disney World resorts, whether for a conference or vacation,there are two things you need to know:
- Nothing is within a short "walking distance", you need to take a bus or boat to get anywhere
- Despite this, you will be doing a lot of walking, so wear comfortable shoes!
Pulse encouraged everyone to blog and take pictures posted onto FlickR, here are a few from Sunday:
|Lou and Elizabeth from [Syclo], an IBM Business Partner||Mike and Megha from [Birlasoft] show off their accreditation|
|Greg Tevis explains FilesX, recently acquired by IBM||Kevin and Diana from [Odin Technologies] that manage RFID tags|
|A banner for our[IBM System Storage DCS9550] disk system for "deep computing" workloads||Elizabeth from[Eaton Powerware]|
|I spoke to Mac Guidera, IBM tech lead for Lotus Greenhouse, about IBM'sProject Big Green||Laura Guio, IBM director of the Tivoli SWAT team, on the left.|

Well, the weather here has turned awful, so I better turn off my computer to avoid lightning-strike damage.
For those looking for something to do to enjoy the "4th of July" US Independence day holiday tomorrow, thereis the [Team America: Sing-a-long at Tucson's Loft Cinemaat 6pm, you can still see the fireworks after the show is over. I did this last year and it was a lot of fun.
Also, you can check out the IBM Wimbledon build on Second Life. Here's the SLURL:[http://slurl.com/secondlife/IBM%207/133/180/23].Several IBMers will be "in world" at this virtual location on 4th of July. For all of my readers looking to check out Second Life, see what IBM can do, or talk to people who are familiar with this technology, here's your chance.
As for me, I'll be spending my "long weekend" in an airplane. Here's my travel schedule.
- July 7-11: Tokyo, Japan - business meetings with IBM sales reps
- July 13-18: Mumbai, India - business meetings with IBM business partners
- July 24-27: San Diego, California - [Comic-Con] and [Octagon Global Recruiting] -- my thanks to ABC, theproducers of the TV show "LOST", and the [Dharma Initiative] for the invitation!
If you will be at any of these locations on any of these dates and want to meet up, please let me know.You can click on the "send e-mail to Tony Pearson" button on the right panel of my blog.
(I was hoping that while I was in Asia, I could stop over and visit the schools I helped in Nepal and my friends at the Open Learning Exchange [OLE Nepal] as part of the One Laptop PerChild [OLPC Nepal] program, but I did not get all my ducks lined up for this with the appropriate travel approvals, visas and logistics. My apologies to Bryan, Sulochan and the rest of the team. Perhaps next year!)
Enjoy your weekend!
