I attended the main tent sessions on Day 2 (Monday). The focuswas on Visibility, Control and Automation.
- Steve Mills
Steve is IBM senior VP and Group Executive of the IBM Software Group, and presented someinsightful statistics from the IBM Global Technology Outlookstudy, some recent IBM wins, and other nuggets of IT trivia:
- In 2001, there were about 60 million transistors per humanbeing. By 2010, this is estimated to increase to one billion per human
- In 2005, there were about 1.3 billion RFID tags, by 2010this is estimated to grow to over 30 billion
- IBM helped the City of Stockholm, Sweden, reduce traffic congestion 20-25% using computer technology
- Only about 25% data is original, the remaining75% is replicated
- In 2007, there were approximately 281 Exabytes (EB), expected to increase to 1800 EB by the year 2011
- 70 percent of unstructured data is user-created content, but 85 percent of this will be managed by enterprises
- Only 20% of data is subject to compliance rules and standards, and about 30% subject to security applications
- Human error is the primary reason for breaches, with34% of organizations experiencing a major breach in 2006
- 10% of IT budget is energy costs (power and cooling), and thiscould rise to 50% in the next decade
- 30 to 60 percent of energy is wasted. During the next 5 years, people will spend as much on energy as they will on new hardware purchases.
- Al Zollar
Al Zollar is the General Manager of IBM Tivoli. He discussedthe 20 some recent software acquisitions, including Encentuate and FilesX earlier this year.
"The time has come to fully industrialize operations" -- Al Zollar
What did Al mean about "industrizalize"? This is theclosed-loop approach of continuous improvement, including design, delivery and management.
Al used several examples from other industries:
- Henry Ford used standardized parts and processautomation. Assembly of an automatobile went from 12 hours by master craftsmen, to delivering a new model T every 23 seconds off anassembly line.
- Power generation was developed by Thomas Edison. A satellite picture showed the extent of the [Blackout of 2003 in Northeast US and Canada]. The time for "smart grid" has arrived, making sensors andmeters more intelligent. This allows non-essential IP-enabled appliances in our home or office to be turned off to reduce energy consumption.
- [McCarran International Airport] integrated the management of 13,000 assets with IBM Tivoli Maximo Enterprise Asset Management (EAM) software, and was able to increase revenues through more accurate charge-back. Unlike traditional EnterpriseResource Planning (ERP) applications, EAM offers the deep management of four areas: production equipment, facilities, transportation, and IT.
When compared to these other industries, management of IT is in itsinfancy. The expansion of [Web 2.0] and Service-Oriented Architecture [SOA] is driving this need.What people need is a "new enterprise data center" that IBM Tivoli software can help you manage across operational boundaries. IBM can integrate through open standards with management software from Cisco, Sun, OracleMicrosoft, CA, HP, BMC Software, Alcatel Lucent, and SAP.Together with our ecosystems of technology partners, IBM ismeeting these challenges.
IBM clients have achieved return on investment from gettingbetter control of their environment. This week there are client experience presentations Sandia National Labs, Spirit AeroSystems, Bank of America, and BT Converged communication services.
- Live Demo
Chris O'Connor used some of his staff as "actors" to show an incredible live demo of various Tivoli and Maximo products for the mythical launch of "Project Vitalize", thenew online web store for a new "Aero Z bike" from the mythical VCA Bike and Motorcycle company.
Shoel Perelman played the role of "CIO".The CIO locked down all spending, and asked the IT staff to make the shift from bricks-and-mortar to web salesof this new product on in 15 months. While the company andsituation were mythical, all the products that were part of thelive demo are all readily available.The CIO had three goals:
What do we have? where is it? what's connected to what?Traditionally, these would be answered from lists in spreadsheets.The CIO had a goal to deploy IBM Tivoli Application DependenceDiscover Manager (TADDM) which discovered all hardware and software,with an easy to understand view, and how each piece serves the business applications.
Each of the teams have processes, and needed them consistent andrepeatable, tightly linked together. Time is often wasted on thephone coordinating IT changes. For this, the CIO had a goalto deploy Tivoli Change and Configuration Management Database (CCMDB) for "strict change control".The process dashboard is accessible for all teams, to see how all projects are progressing. There is also aCompliance dashboard, which identifies all changes by role, clearly spelling out who can do what.
There is a lot of computerized machinery, Manufacturing assets and robotics. The CIO set a goal to "do more with existing people", and needed to automate key processes.Sales rep wanted to add a new distributor to key web portal.This was all done through their "service catalog", When they needed to deploy a new application, they were able to find servers with available capacity and adjust using automatic provisioning. Thanks to IBM, the IT staff no longer get paged at 3am in the morning, and fewer days are spent in the "war room". They now have confidence that thelaunch will be successful.
Ritika Gunnar played the role of "Operations manager". She highlightedfive areas:
- "Service viewer" dashboard with green/yellow/red indicators forall of their edge, application and datbase servers. This allowsher to get data 4-5 times faster and more accurate.
- Tivoli Enterprise Portal eliminates bouncingaround various products.
- Tivoli Common Reporting for CPU utilization of all systems, helps find excess capacity usingIBM Tivoli Monitor
- On average, 85 percent of problems are caused by IT changes to the environment. IBM can help find dependencies, so that changes in one area do not impact other areas unexpectedly
- Process Automation will Show changes that have been completed, in progress, or overdue.She can see all steps in a task or change request. A"workflow" automates all the key steps that need to be taken.
Laura Knapp played the role of "Facilities manager". She wanted to See all processes that apply to her work using a role-based process dashboard. The advantage of using IBM is that it changes work habits, reduces overtimeby 42 percent, improves morale. The IT staff now works as team,collaborates more, and jobs get done faster with fewer mistakes.Employees are online, accessing, monitoring and managing dataquicker. In days not weeks.
IBM Tivoli Enterprise Console (TEP) served as a common vehicle.She was able to pull up floor plan online, displaying all of the managed assets and mapped features. With the temperature overlay from Maximo Spatial, she was able to review hot spots on data center floor. Heat can cause servers to fail or shut down.
Power utilization chart at peak loadsCan now anticipate, predict and watch power consumption,and were able to justify replacement with newer, more energy-efficient equipment.
The CIO got back on stage, and explained the great success of thelaunch. They use Webstore usage tracking, security tools tracking all new registrations, and trackingserver and storage load.It now only takes hours, not weeks, to add new business partners and distributors.Tivoli Service Quality Assurance toolstrack all orders placed, processed, and shipped.Faster responsiveness is competitive advantage. TheirIT department is no longer seen as stodgy group, but as a world classorganization.
The live demo showed how IBM can help clients with rapid decisionmaking, speed and accuracy of change processes, and automation to take actions quickly. The result is a strong return on investment (ROI).
- Liz Smith
Liz Smith, IBM General Manager of Infrastructure Services, presented the results of an IBM survey to CEOs and CIOs asking questions like: What is the next big impact? Where are you investing?What will new datacenter look like?
The five key traits they found for companies of the future:
- They were hungry for change
- Innovative beyond customer imagination
- Globally integrated
- Disruptive by nature
- Genuine, not just generous
The IT infrastructure must be secure, reliable, and flexible.Taking care of environment is a corporate responsibility, notjust a way to reduce costs.
The five entry points for IBM Service Management: Integrate, Industrialize,Discover,Monitor and Protect.IBM Service management and compliance are critical for theGlobally Integrated Enterprise, with repeatable, scalable and consistent processes that enablechange to an automated workflow. This reduces errors, risks and costs, and improves productivity.IBM has talent, assets and experience to help any client get there.
- Lance Armstrong
Lance lives in Austin, TX, where IBM Tivoli is headquartered,so this made a good choice as a keynote speaker.He is best known for winning seven "Tour de France" bicycle races in a row, but he spoke instead gave an inspirational talk about how he survived cancer.
In 1996, Lance was diagnosed with cancer. Surprisingly, He said it was thegreatest thing that happened to him, and gave him new perspective on his life, family and the sport ofbicycling.Back then, there wasn't a webMD, Google or other Web 2.0 socialnetworking sites for Lance to better understand what he wasgoing through, learn more about treatment options, or find othersgoing through the same ordeal.
After his treatment, he was considered "damaged goods" by manyof the leading European bicycle teams. So, he joined the US Postal Serviceteam, not known for their wins, but often invited to sell TVrights to American audiences. Collaborating with his coachesand other members of his team, he revolutionized the bicycling sport, analyzed everything about the race, and built up morale.He won the first "yellow jersey" in 1999, and did so each yearfor a total of seven wins.
Lance formed the [Livestrong foundation] to help other cancer survivors. Nike came to him and proposed donating 5 million "rubber bracelets"colored yellow to match his seven yellow jerseys, with the name "Livestrong" embossed on them, that his foundation couldthen sell for one dollar apiece to raise funds. What some thought was a silly idea at first has started amovement.At the 2004 Olympics, many athletes from all nations and religious backgrounds, wore these yellow braceletsto show solidarity with this cause.To date, the foundation has sold over 72 million yellow bracelets, and these have served to provide a symbol,a brand, a color identity, to his cause.
He explained that doctor's have a standard speech to cancer survivors.As a patient, you can go out this doorway and never tell anyone,keep the situation private. Or you can go out this other doorway, you tell everybody your story. Lance chose the latter, and he felt it was the best decision he ever made.He wrote a book titled [It's Not About the Bike: My Journey Back to Life].
His call to action for the audience: find out what can you do to make a difference.A million non-governmental organizations[NGO] have started in the past 10 years. Don't just give cash, also give your time and passion.
Lots of things to think about!

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'm glad this is the final day of the IBM Systems Technical Conference (STC08) here in Los Angeles.While I enjoyed the conference, one quickly reaches saturation point with all the information presented.
- XIV Architecture Overview
Before this conference, many of the attendees didn't understandIBM's strategy, didn't understand Web 2.0 and Digital archive workloads,and didn't understand why IBM acquired XIV to offer "yet another disk systemthat servers LUNs to distributed server platforms." Brian Shermanchanged all that!
Brian Sherman, IBM Advanced Technical Support (ATS), is part of the exclusive dedicated XIVtechnical team to install these boxes at client locations, so he is very knowledgeable with the technical aspects of the architecture. He presented what the current XIV-branded model that clients can purchase now in select countries, and what the IBM-branded model will change when available worldwide.
Those who missed my earlier series on XIV can find them here:
Beyond this, Brian gave additional information on how thin provisioning, storage pools, disk mirroring, consistency groups, management consoles, and microcode updates are implemented.
- N series and VMware Deep Dive
Norm Bogard, IBM Advanced Technical Support, presented why the IBM N series makes such great disk storage for VMware
deployments. This wasclearly labeled as a "deep dive", so anyone who got lost in all of theacronyms could not blame Norm for misrepresentation.
IBM has been doing server virtualization for over 40 years, so it makes sense thatit happens to be the number one reseller of VMware offerings.VMware ESX server is a hypervisor that runs on x86 host, and provides an emulationlayer for "guest Operating Systems". Each guest can hvae one or more virtualdisks, which are represented by VMware as VMDK files. VMware ESX server acceptsread/write requests from the guests, and forwards them on to physical storage.Many of VMware's most exciting features requires storage to be external to thehost machine. [VMotion]allows guests to move from one host to another, [Distributed Resource Scheduler (DRS)]allows a set of hosts to load-balance the guestsacross the hosts, and [High Availability (HA)] allows the guests on a failed hostto be resurrected on a surviving host. All of these require external disk storage.
ESX server allows up to 256 LUNs, attached via FCP and/or iSCSI, and up to 32 NFS mount points. Across LUNs, ESX server uses VMFS file system, which is a clusteredfile system like IBM GPFS that allows multiple hosts to access the same LUNs.ESX server has its own built-in native multipathing driver, and even provides FCP-iSCSIand iSCSI multipathing. In other words, you can have a LUN on an IBM System Storage N series thatis attached over both FCP and iSCSI, so if the SAN switch or HBA fails, ESX servercan failover to the iSCSI connection.
ESX server can use NFS protocol to access the VMDK files instead. While the default is only 8 NFS mount points, you can increase this to 32 mount points. NAS can takeadvantage of Link Aggregate Control Protocol [LACP] groups, what some call "trunking" or "EtherChannel". This is the ability to consolidate multiple streams onto fewer inter-switch Ethernet links, similar to what happens on SAN switches.For the IBM N series, IBM recommends a "fixed" path policy, rather than "most recently used".
IBM recommends disabling SnapShot schedules, and setting the Snap reserve to 0 percent.Why? A snapshot of an ESX server datastore has the VMDK files of many guests, all of which would have had to quiesce or stop to make the data "crash consistent" for theSnapshot of the datastore to even make any sense. So, if you want to take Snapshots, itshould be something you coordinate with the ESX server and its guest OS images, and notscheduled by the N series itself.
If you are running NFS protocol to N series, you can turn off the "accesstime" updates. In normal file systems, when you read a file, it updates the"access time" in the file directory. This can be useful if you are looking forfiles that haven't been read in a while, such as software that migrates infrequentlyaccessed files to tape. Assuming you are not doing that on your N series, you might as well turnoff this feature, and reduce the unnecessary write activity to the IBM N series box.
ESX server can also support "thin provisioning" on the IBM N series. There isa checkbox for "space reserved". Checked means "thick provisioning" and uncheckedmeans "thin provisioning". If you decide to use "thin provisioning" with VMware,you should consider setting AutoSize to automatically increase your datastorewhen needed, and to auto-delete-snap your oldest snapshots first.
The key advantage of using NFS rather than FCP or iSCSI is that it eliminates theuse of the VMFS file system. IBM N series has the WAFL file system instead, andso you don't have to worry about VMFS partition alignment issue. Most VMDK aremisaligned, so the performance is sub-optimal. If you can align each VMDK to a32KB or 64KB boundary (depending on guest OS), then you can get better performance.WAFL does this for you automatically, but VMFS does not. For Windows guests, use "Windows PE" to configurecorrectly-aligned disks. For UNIX or Linux guests, use "fdisk" utility.
- What Industry Analysts are saying about IBM
Vic Peltz gave a presentation highlighting the accolades from securities analysts, IT analysts, and newsagencies about IBM and IBM storage products. For example, analysts like that IBM offersmany of the exciting new technologies their clients are demanding, like "thin provisioning", RAID-6 double-drive protection,SATA and Solid State Disk (SSD) drive technology.Analysts also like that IBM is open to non-IBM heterogeneous environments. Whereas EMC Celerra gateways supportonly EMC disk, IBM N series gateways and IBM SAN Volume Controller support a mix of IBM and non-IBM equipment.
Analysts also like IBM's "datacenter-wide" approach to issues like security and "Green IT". Rather than focusingon these issues with individual point solutions, IBM attacks these challenges with a complete"end-to-end" solution approach. A typical 25,000 square foot data center consumes $2.6 million dollars USD in power andcooling today, and IBM has proven technologies to reduce this cost in half. IBM's DS8000 on average consume26.5 to 27.8 percent less electricity than a comparable EMC DMX-4 disk system. IBM's tape systemsconsume less energy than comparable Sun or HP models.
- IBM iDataPlex product technical presentation
Vallard Benincosa, IBM Technical Sales Specialist, presented the recently-announced [IBM System x iDataPlex].This is designed for our clients that have thousands of x86 servers, that buy servers "racks at a time", tosupport Web 2.0 and digital archive workloads. The iDataPlex is designed for efficient power and cooling,rapid scalability, and usable server density.
iDataPlex is such a radical design departure, that it might be difficult to describe in words.Most racks take up two floor tiles, each tile is 2 foot by 2 foot square. In that space, a traditionalrack would have servers that were 19 inches wide slide in horizontally, with flashing lights and hot-swappabledisks in the front, and all the power supply, fans and networking connections in the back. Even with IBM BladeCenter,you have chassis in these racks, and then servers slide in vertically in the front, and all of the power supply, fanand networking connections in the back. To access these racks, you have to be able to open the door on boththe front and back. And the cooling has to go through at least 26.5 inches from the front of the equipment to the back.
iDataPlex turns the rack sideways. Instead of two feet wide, and four feet deep, it is four feet wide, and two feet deep.This gives you two 19 inch columns to slide equipment into, and the air only has to travel 15 inches from frontto back. Less distance makes cooling more efficient.
Next, iDataPlex makes only thing in the back the power cord, controlled by an intelligent power distribution unit (iPDU) so you can turnthe power off without having to physically pull the plug. Everything else is serviced from the front door.This means that the back door can now be an optional "Rear Door Heat Exchanger" [RDHX] that is filled with running water to makecooling the rack extremely efficient. Water from a cooler distirubtion unit (CDU) can power about threeto four RDHX doors.
Let's say you wanted to compare traditional racks with iDataPlex for 84 servers. You can put 42 "1U" serversin two racks each, each rack requires 10 kVA (kilo-volt-amps) so you give it two 8.6 kVA feeds each, that is fourfeeds, and at $1500-2000 dollars USD per month, will cost you $6000-8000. The iDataPlex you can fit 84 serversin one 20 kVA rack, with only three 8.6 kVA feeds, saving you $1500-2000 dollars USD per month.
Fans are also improved. Fan efficiency is based on their diameter, so small fans in 1U servers aren't as effective as iDataPlex's 2U fans, saving about 12-49W per server. Whereas typical 1U server racks spend 10-20percent of their energy on the fans, the iDataPlex spends only about 1 percent, saving 8 to 36 kWH per year per rack.
Each 2U chassis snaps into a single power supply and a bank of 2U fans. A "Y"power cord allows you to have one cord for two power supplies. A chassis can hold either two small server "flexnodes"or one big "flexnode". An iDataPlex rack can hold up to 84 small servers or 42 big servers. Since each "Y" cord can power up to four "flexnode" servers, you greatly reduce the number of PDU sockets taken,leaving some sockets available for traditional 1U switches.
The small "flexnode" server can have one 3.5 inch HDD, or two 2.5 inch HDD, either SAS or SATA, and the big "flexnode" can have twice these.If you need more storage, there is a 2U chassis that holds five 3.5 inch HDD or eight 2.5 inch HDD. These areall "simple-swappable" (servers must be powered down to pull out the drives). For hot-swappable drives, a 3Uchassis with twelve 3.5 inch SAS or SATA drives.
The small "flexnode" server has one [PCI Express] slot, the big servers have two. Thesecould be used for [Myrinet] clustering. With only 25W power,the PCI Express slots cannot support graphics cards.
The iDataPlex is managed using the "Extreme Cluster Administration Toolkit" [XCAT]. This is an open source project under Eclipse that IBM contributes to.
Finally was the concept of "pitch". This is the distance from the center of one "cold aisle" to the next "cold aisle".On typical data centers, a pitch is 9 to 11 tiles. With the iDataPlex it is only three tiles when using the RDHX doors, or six tiles without. Most data centers run out of power and cooling before they run out of floor space, so having more dense equipmentdoesn't help if it doesn't also use less electricity.Since the iDataPlex uses 40 percent less power and cooling, you can pack more racks persquare foot of an existing data center floor with the existing power and cooling available. That is what IBM calls "usable density"!
- What Did You Say? Effective Questioning and Listening Techniques
Maria L. Anderson, IBM Human Resources Learning, gave this "professional development" talk. I deal with different clients every week, so I fully understand that there is a mix of art and science incrafting the right questions and listening to the responses.The focus was on howto ask better questions and improve the understanding and communication during consultative engagements. Thisinvolves the appropriate mix of closed and open-ended questions, exchanging or prefacing as needed. This wasa good overview of the ERIC technique (Explore, Refine, Influence, and Confirm).
Well, that wraps up my week here in Los Angeles.Special thanks to my two colleagues, Jack Arnold and Glenn Hechler, both from the Tucson Executive Briefing Center,who helped me prepare and review my presentations!

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.

This is the second day of our Systems Technology Conference (STC08) in Los Angeles, California.We have over 700 break-out sessions, packed in 16 times slots across 47 rooms.
- IBM Strategy - the New Enterprise Data Center
In February, IBM launched its corporate-wide strategy for the "new enterprise data center", which I discussedalready in my post[Is your data center ready for the future?]
My session was the first in the morning, at 8:30am, but managed to pack the room full of people. A few looklike they just rolled in from Brocade's special get-together in Casey's Irish Pub the night before.I presented how IBM's storage strategy for the information infrastructure fits into the greater corporate-wide themes.To liven things up, I gave out copies of my book[Inside System Storage: Volume I] to those who asked or answered the toughest questions.
- Data Deduplication and IBM Tivoli Storage Manager (TSM)
IBM Toby Marek compared and contrasted the various data deduplication technologies and products available, andhow to deploy them as the repository for TSM workloads. She is a software engineer for our TSM software product,and gave a fair comparison between IBM System Storage N series Advanced Single Instance Storage (A-SIS), IBMDiligent, and other solutions out in the marketplace.If you are going to combine technologies, then it isbest to dedupe first, then compress, and finally encrypt the data. She also explained about the many cleverways that TSM does data reduction at the client side greatly reduces the bandwidth traffic over the LAN,as well as reducing disk and tape resources for storage. This includes progressive "incremental forever" backup for file selection, incremental backups for databases, and adaptive sub-file backup.Because of these data reduction techniques, you may not get as much benefit as deduplication vendors claim.
- The Business Value of Energy Efficiency Data Centers
Scott Barielle did a great job presenting the issues related to the Green IT data center. He is part of IBM"STG Lab Services" team that does energy efficiency studies for customers. It is not unusual for his teamto find potential savings of up to 80 percent of the Watts consumed in a client's data center.
IBM has done a lot to make its products more energy efficient. For example, in the United States, most datacenters are supplied three-phase 480V AC current, but this is often stepped down to 208V or 110V with powerdistribution units (PDUs). IBM's equipment allows for direct connection to this 480V, eliminating the step-downloss. This is available for the IBM System z mainframe, the IBM System Storage DS8000disk system, and larger full-frame models of our POWER-based servers, and will probably be rolled out to someof our other offerings later this year. The end result saves 8 to 14 percent in energy costs.
(Last October, IBM Randy Malik made a similar case in his presentation:[HighVoltage Distributions])
Scott had some interesting statistics. Typical US data centers only spend about 9 percent of their IT budgeton power and cooling costs. The majority of clients that engage IBM for an energy efficiency study are not tryingto reduce their operational expenditures (OPEX), but have run out, or close to running out, of total kW ratingof their current facility, and have been turned down by their upper management to spend the average $20 million USDneeded to build a new one. The cost of electricity in the USA has risen very slowly over the past 35 years, andis more tied the to fluctuations of Natural Gas than it is to Oil prices.(a recent article in the Dallas News confirmed this:["As electricity rates go up, natural gas' high prices, deregulation blamed"])
- Cognos v8 - Delivering Operational Business Intelligence (BI) on Mainframe
Mike Biere, author of the book [BusinessIntelligence for the Enterprise], presented Cognos v8 and how it is being deployed for the IBMSystem z mainframe. Typically, customers do their BI processing on distributed systems, but 70 percent of the world's business data is on mainframes, so it makes sense to do yourBI there as well. Cognos v8 runs on Linux for System z, connecting to z/OS via [Hypersockets].
There are a variety of other BI applications on the mainframe already, including DataQuant,AlphaBlox, IBI WebFocus and SAS Enterprise Business Intelligence. In addition to accessing traditional onlinetransaction processing (OLTP) repositories like DB2, IMS and VSAM, using the [IBM WebSphere ClassicFederation Server], Cognos v8 can also read Lotus databases.
Business Intelligence is traditionally query, reporting and online analytics process (OLAP) for the top 10 to 15 percent of the company, mostly executives andanalysts, for activities like business planning, budgeting and forecasting. Cognos PowerPlay stores numericaldata in an [OLAP cube] for faster processing.OLAP cubes are typically constructed with a batch cycle, using either "Extract, Transfer, Load" [ETL], or "Change Data Capture" [CDC], which playsto the strength of IBM System z mainframe batch processing capabilities.If you are not familiar with OLAP, Nigel Pendse has an article[What is OLAP?] for background information.
Over the past five years, BI is now being more andmore deployed for the rest of the company, knowledge workers tasked with doing day-to-day operations. Thisphenomenom is being called "Operational" Business Intelligence.
For more on this, see the IBM Systems Magazine article [Upgrade Your Mainframe with Operational Business Intelligence].
- IBM GPFS - Fundamentals and What's New
IBM Glen Corneau, who is on the Advanced Technical Support team for AIX and System p, presented the IBMGeneral Parellel File System (GPFS), which is available for AIX, Linux-x86 and Linux on POWER.Unfortunately, many of the questions were related to Scale Out File Services (SOFS), which my colleague GlennHechler was presenting in another room during this same time slot.
GPFS is now in its 11th release since its introducing in 1997. All of the IBM supercomputers on the [Top 500 list] use GPFS. The largest deployment of GPFS is 2241 nodes.A GPFS environment can support up to 256 file systems, each file system can have up to 2 billion filesacross 2 PB of storage. GPFS supports "Direct I/O" making it a great candidate for Oracle RAC deployments.Oracle 10g automatically detects if it is using GPFS, and sets the appropriate DIO bits in the stream totake advantage of GPFS features.
Glen also covered the many new features of GPFS, such as the ability to place data on different tiers ofstorage, with policies to move to lower tiers of storage, or delete after a certain time period, all conceptswe call Information Lifecycle Management. GPFS also supports access across multiple locations and offersa variety of choices for disaster recovery (DR) data replication.
Perhaps the only problem with conferences like this is that it can be an overwhelming["fire hose"] of information!
