Dave Hitz from Network Appliance has a wonderful discussion of "branding": What do Marketing People Mean When They Say Brand?
A lot of people ask me about IBM branding, as we have recently changed brands. In the past we had two separate brands, one for servers (eServer) and one for storage (TotalStorage). These would be fine if we wanted to promote their independence, but customers today want synergy between servers and storage, they want systems that work well together.
Last year, in response to market feedback, we crated a new brand, "IBM Systems" and put all the server and storage product lines under one roof. Over time, we will transition from TotalStorage to System Storage naming. This will occur with new products, and major versions of existing products.
Two other phrases you will hear in the names of our offerings are "Virtualization Engine" and "Express". These are portfolio identifiers. The Virtualization Engine identifier was created to emphasize our leadership in system virtualization, and we have products that span product lines with this identifier.
The Express identifier was created to emphasize our focus on Small and Medium sized business (SMB). It spans not just servers and storage, but across other offerings from other IBM divisions.
Of course, just renaming products and services isn't enough. Systems don't work together just because they have similar names, are covered in similar "Apple white" plastic, or have similar black bezels. Obviously, thoughtful and collaborative design are needed, with the appropriate amounts of engineering and testing. IBM is aligning its server and storage development so that the IBM Systems brand keeps its promise.

With price and joy, I shipped my baby off today. My "baby" in this case was an [XS School Server
]that I built and configured with software as a platform to developan [Educational Blogging System
] for[Proyecto Ceibal
] who are the "One Laptop Per Child" groupin Uruguay [OLPC Uruguay
(Earlier this year, I build a test XS School Server that was used to help and support [OLPC Nepal] by working with their local NGO team[OLE Nepal]. I wrote about this back in Februaryin my post [Understandingthe LAMP platform for Web 2.0 workloads].)
Based on this success, and perhaps because I am also fluent in Spanish, I was asked to help with Proyecto Ceibal, the team for OLPC Uruguay. Normally theXS school server resides at the school location itself, so that even if the internet connection is disrupted or limited, the school kids can continue to access each other and the web cache content until internet connection is resumed.However, with a diverse developmentteam with people in United States, Uruguay, and India, we first looked to Linux hosting providers that wouldagree to provide free or low-cost monthly access. We
spent (make that "wasted") the month of May investigating.Most that I talked to were not interested in having a customized Linux kernel on non-standard hardware on their shop floor, and wanted instead to offer their own standard Linux build on existing standard servers, managed by theirown system administrators, or were not interested in providing it for free. Since the XS-163 kernel is customizedfor the x86 architecture, it is one of those exceptions where we could not host it on an IBM POWER or mainframe as a virtual guest.
This got picked up as an [idea] for the Google's[Summer of Code] and we are mentoring Tarun, a 19-year-old student to actas lead software developer. However, summer was fast approaching, and we wanted this ready for the next semester. In June, our project leader, Greg, came up with a new plan. Build a machine and have it connected at an internet service provider that would cover the cost of bandwidth, and be willing to accept this with remote administration. We found a volunteer organization to cover this -- Thank you Glen and Vicki!
We found a location, so the request to me sounded simple enough: put together a PC from commodity parts that meet the requirements of the customizedLinux kernel, the latest release being called [XS-163]. The server would have two disk drives, three Ethernet ports, and 2GB of memory; and be installed with the customized XS-163 software, SSHD for remote administration, Apache web server, PostgreSQL database and PHP programming language.Of course, the team wanted this for as little cost as possible, and for me to document the process, so that it could be repeated elsewhere. Some stretch goals included having a dual-boot with Debian 4.0 Etch Linux for development/test purposes, an alternative database such as MySQL for testing, a backup procedure, and a Recover-DVD in case something goes wrong.
Some interesting things happened:
- The XS-163 is shipped as an ISO file representing a LiveCD bootable Linux that will wipe your system cleanand lay down the exact customized software for a one-drive, three-Ethernet-port server. Since it is based on Red Hat's Fedora 7 Linux base, I found it helpful to install that instead, and experiment moving sections of code over.This is similar to geneticists extracting the DNA from the cell of a pit bull and putting it into the cell for a poodle. I would not recommend this for anyone not familiar with Linux.
I also experimented with modifying the pre-built XS-163 CD image by cracking open the squashfs, hacking thecontents, and then putting it back together and burning a new CD. This provided some interesting insight, but in the end was able to do it all from the standard XS-163 image.
- Once I figured out the appropriate "scaffolding" required, I managed to proceed quickly, with running versionsof XS-163, plain vanilla Fedora 7, and Debian 4, in a multi-boot configuration.
- The BIOS "raid" capability was really more like BIOS-assisted RAID for Windows operating system drivers. This"fake raid" wasn't supported by Linux, so I used Linux's built-in "software raid" instead, which allowed somepartitions to be raid-mirrored, and other partitions to be un-mirrored. Why not mirror everything? With two160GB SATA drives, you have three choices:
- No RAID, for a total space of 320GB
- RAID everything, for a total space of 160GB
- Tiered information infrastructure, use RAID for some partitions, but not all.
The last approach made sense, as a lot of of the data is cache web page images, and is easily retrievable fromthe internet. This also allowed to have some "scratch space" for downloading large files and so on. For example,90GB mirrored that contained the OS images, settings and critical applications, and 70GB on each drive for scratchand web cache, results in a total of 230GB of disk space, which is 43 percent improvement over an all-RAID solution.
- While [Linux LVM2] provides software-based "storage virtualization" similar to the hardware-based IBM System Storage SAN Volume Controller (SVC), it was a bad idea putting different "root" directories of my many OS images on there. With Linux, as with mostoperating systems, it expects things to be in the same place where it last shutdown, but in a multi-boot environment, you might boot the first OS, move things around, and then when you try to boot second OS, it doesn'twork anymore, or corrupts what it does find, or hangs with a "kernel panic". In the end, I decided to use RAIDnon-LVM partitions for the root directories, and only use LVM2 for data that is not needed at boot time.
- While they are both Linux, Debian and Fedora were different enough to cause me headaches. Settings weredifferent, parameters were different, file directories were different. Not quite as religious as MacOS-versus-Windows,but you get the picture.
- During this time, the facility was out getting a domain name, IP address, subnet mask and so on, so I testedwith my internal 192.168.x.y and figured I would change this to whatever it should be the day I shipped the unit.(I'll find out next week if that was the right approach!)
- Afraid that something might go wrong while I am in Tokyo, Japan next week (July 7-11), or Mumbai, India the following week (July 14-18), I added a Secure Shell [SSH] daemon that runs automaticallyat boot time. This involves putting the public key on the server, and each remote admin has their own private key on their own client machine.I know all about public/private key pairs, as IBM is a leader in encryption technology, and was the first todeliver built-in encryption with the IBM System Storage TS1120 tape drive.
- To have users have access to all their files from any OS image required that I either (a) have identical copieseverywhere, or (b) have a shared partition. The latter turned out to be the best choice, with an LVM2 logical volumefor "/home" directory that is shared among all of the OS images. As we develop the application, we might findother directories that make sense to share as well.
- For developing across platforms, I wanted the Ethernet devices (eth0, eth1, and so on) match the actual ports they aresupposed to be connected to in a static IP configuration. Most people use DHCP so it doesn't matter, but the XSsoftware requires this, so it did. For example, "eth0" as the 1 Gbps port to the WAN, and "eth1/eth2" as the two 10/100 Mbps PCI NIC cards to other servers.Naming the internet interfaces to specific hardware ports wasdifferent on Fedora and Debian, but I got it working.
- While it was a stretch goal to develop a backup method, one that could perform Bare Machine Recovery frommedia burned by the DVD, it turned out I needed to do this anyways just to prevent me from losing my work in case thingswent wrong. I used an external USB drive to develop the process, and got everything to fit onto a single 4GB DVD. Using IBM Tivoli Storage Manager (TSM) for this seemed overkill, and [Mondo Rescue] didn't handle LVM2+RAID as well as I wanted, so I chose [partimage] instead, which backs up each primary partition, mirrored partition, or LVM2 logical volume, keeping all the time stamps, ownerships, and symbolic links in tact. It has the ability to chop up the output into fixed sized pieces, which is helpful if you are goingto burn them on 700MB CDs or 4.7GB DVDs. In my case, my FAT32-formatted external USB disk drive can't handle files bigger than 2GB, so this feature was helpful for that as well. I standardized to 660 GiB [about 692GB] per piece, sincethat met all criteria.
(The mainframe equivalent is DFSMShsm or DFSMSdss DUMP, which by the way can be used with Linux for System z DASD CKD partitions. See this helpful[HOWTO back up your Linux partitions and volumes through z/OS] guide.)
- The folks at [SysRescCD] saved the day. The standard "SysRescueCD" assigned eth0, eth1, and eth2 differently than the three base OS images, but the nice folks in France that write SysRescCD created a customized[kernel parameter that allowed the assignments to be fixed per MAC address ] in support of this project. With this in place, I was able to make a live Boot-CD that brings up SSH, with all the users, passwords,and Ethernet devices to match the hardware. Install this LiveCD as the "Rescue Image" on the hard disk itself, and also made a Recovery-DVD that boots up just like the Boot-CD, but contains the 4GB of backup files.
For testing, I used Linux's built-in Kernel-based Virtual Machine [KVM]which works like VMware, but is open source and included into the 2.6.20 kernels that I am using. IBM is the leadingreseller of Vmware and has been doing server virtualization for the past 40 years, so I am comfortable with thetechnology. The XS-163 platform with Apache and PostgreSQL servers as a platform for [Moodle], an open source class management system, and the combination is memory-intensive enough that I did not want to incur the overheads running production this manner, but it wasgreat for testing!
With all this in place, it is designed to not need a Linux system admin or XS-163/Moodle expert at the facility. Instead, all we need is someone to insert the Boot-CD or Recover-DVD and reboot the system if needed.
Just before packing up the unit for shipment, I changed the IP addresses to the values they need at the destination facility, updated the [GRUB boot loader] default, and made a final backup which burned the Recover-DVD. Hopefully, it works by just turning on the unit,[headless], without any keyboard, monitor or configuration required. Fingers crossed!
So, thanks to the rest of my team: Greg, Glen, Vicki, Tarun, Marcel, Pablo and Said. I am very excited to bepart of this, and look forward to seeing this become something remarkable!

IDC announced that IBM was number #1 in storage hardware (disk and tape combined)for 2006. Here are some excerpts from the IBM press release:
The newly released May 2007 report  by leading industry analyst firm IDC, "Worldwide Combined Disk and Tape Storage 2006 Market Share Update," shows IBM in the #1 overall position for all disk and tape storage hardware for the full year 2006.
In a total disk and tape storage hardware segment that increased to $28.2 billion in 2006, IBM captured 22.2 percent of the combined revenue for full year 2006, besting HP's 20.9 percent and EMC's 13.2 percent.
Five years ago, IBM was only #3 in this area, butis this new standing from IBM doing things better, or HP and EMC doing things poorly? Probably a little of both, but since it's not polite to point out the flaws of others in a blog, I will focus on what IBM is doing right, and I think our leadership in tape accounts for a good measure of this.
The resurgence of tape comes from a variety of factors:
- The focus on being "green", to conserve energy power and cooling costs. Tape is the cheapest storage in this regard, as the tape cartridges only consume power when read or written.
- Government regulations where more data must be stored for longer periods of time, such as theFederal Rules of Civil Procedures (FRCP), Sarbanes-Oxley, SEC regulations, and so on.
- The widening gap in dollars per MB. Advancements in tape are outpacing disk. Disk is slowing down to about 25% improvement year on year, but tape continues its 30-40% improvement curve. A solution like Information Lifecycle Management (ILM) that moves older less valuable data from disk to tape can result in excellent cost savings.
- Exciting "combined storage" solutions like the IBM System Storage DR550 and the IBM Grid Medical Archive Solution (GMAS) that combine disk and tape with internal hierarchy storage management of data, based on policies.
For more details, see IBM's press release.

As I mentioned in my last post, [IBM announces the 60th anniversary of digital tape storage systems]. As promised, I am back in Tucson today to enjoy the festivities.
Ten years ago, I travelled to New York City with my colleague, Randy Fleenor, to present the latest in IBM tape technology for the 50th Anniversary. On Thursday evening that week, the latest movie in the Star Wars saga, Episode II: Attack of the Clones was just released, and it was being shown using the new Digital Light Projection (DLP) technology just around the corner at the Ziegfeld theater! This movie was the first live-action film to be filmed entirely digital. George Lucas saw that digital video was the future, and started the process moving forward with this film.
I convinced Randy to join me, and we arrived at 11:10pm, the movie was scheduled to start at 11pm, so we figured we had only missed a few previews. We walked into a completely empty lobby. I asked for two tickets for the 11pm show at the ticket counter, and was told it was all sold out, and there was a huge line around the building for all the people waiting to see the 1:00am show, and that we might get in to see the 3:00am show.
Randy and I had meetings on Friday morning, so we were not going to wait in line all night to see a 3am show! Just then, a young man comes out of the theater. He said his girlfriend can't make it, and wanted a refund for his two tickets. I pulled out a twenty-dollar bill, offered to buy them directly at face value, and the theater employees approved the transaction. The seats were front row of the balcony section. By then we had missed all the previews and a short bit of the movie, but that was alright with us.
(FTC Disclosure: I am both an employee and stockholder in IBM. The U.S. Federal Trade Commission may consider this a paid, celebrity endorsement of LTO-5 tapes and the LTFS technology. References to other companies are for illustrative purposes and do not represent an endorsement of their products or services.)
Digital recording is ideal for all types of video, including movies, television, and commercial advertisements.
The latest excitement is over IBM's Linear Tape File System™ (LTFS), which IBM donated to the IT industry as open source so that everyone in the world can benefit. This allows tape cartridges to be treated like USB memory sticks, the ultimate in portability of data. It is supported for Windows, Mac OS, and Linux, and already well embraced by the Media-and-Entertainment (M&E) industry.
Last week, IBM announced that it has helped [Greece's AlphaTV with LTFS on LTO-5 tape technology]. Here is an excerpt:
"The move to IBM technology has helped the network shrink its archive from 1,507 to just 388 square feet, representing dramatic systems and energy-cost savings."
"AlphaTV has been broadcasting since 1996, creating and storing all forms of video entertainment, from soap operas and documentaries, to movies and sporting events, and creating a vast video archive along the way. Initially, AlphaTV archived its programming on Sony Beta SP format video cassettes that stored up to 90 minutes of content. Not long after, in need of storage that offered greater density, it turned to DVCPRO format videos that stored up to 120 minutes. But even that format was not allowing the network to keep pace with its ballooning archive, a storage infrastructure that by 2011 spanned more than 1,507 square feet."
"'A Greek TV series stored on 100 DVCPRO tapes took up four shelves in our library, whereas on LTO-5 cartridge now takes up the space of a deck of playing cards,' Constantinos Colombus, chief technology officer at AlphaTV, said in a statement."
"IBM LTFS, an intuitive and graphical file system that provides direct access to data on LTO 5 drives, has enabled AlphaTV to manage, move and share video files much like they can with disk-management systems, by simply dragging and dropping. As a result, file management is easier to do and far more efficient, said Colombus."
To prepare for this anniversary, I spoke with Brad Johns, of [Brad Johns Consulting]. Brad was head of IBM tape marketing for a while, and ran tape customer councils to gather feedback from our largest customers. Brad was my mentor in marketing at IBM from 2003-2007 and has since retired from IBM to start his own consulting practice.
His latest publication is a TCO study entitled [A New Approach to Lowering the Cost of Storing File Archive Information] where he evaluated the 10-year total cost of ownership (TCO) for storage systems to hold file archives.
The comparison was made between Crossroad Systems' Strongbox® with Enterprise tape library, LTO-5 tapes using LTFS, versus a unified disk storage system offering NAS protocols on high-capacity 3TB drives. The findings: the tape-based archive had nearly 80 percent lower TCO than the disk-based solution!
You don't have to be in the middle of the Greek economy to real that is a good value!

Chuck Hollis makes some excellent points about Green Data Center Goes Marketing Mainstream
. He does a great job summarizing EMC's strategy in this area:
- Use VMware to virtualize your x86-based servers
- 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.

Today was the "First Ever Live Virtual Virtualization Tech Fair" sponsored by IBM and VMware. This was a 1-day event hosted by Unisfair.
The day included presentations done at a conference call, along with exhibition booths.
We had an exhibition booth exclusively for "storage virtualization" featuring our IBM System Storage SAN Volume Controller (disk virtualization) and IBM System Storage TS7520 Virtualization Engine (a virtual tape library, or VTL).
People who were logged in were represented in silhouette form. When someone walked into the booth, our army of "booth reps" were able to chat with them and answer their questions. They could also peruse the various online materials we made available about each product.
Here are some of my observations:
- A lot of questions were related to IBM's support for VMware. Although VMware is now currently owned by EMC, pending a spin-off IPO, IBM is its biggest reseller, given IBM's vast experience in server virtualization. Ironically, IBM's SAN Volume Controller supports VMware better than EMC's own storage virtualization product, Invista.
- This was a good opportunity to discuss all the other forms of server virtualization available, such as Xen, Microsoft Virtual Server, Advanced POWER virtualization inside our System p server line,and running thousands of virtual servers on our System z mainframe machines.
- People also familiar with Second Life thought this 2-D "silhouette" version eliminated the need to configure and dress up your avatar as is required in participating in Second Life events. However, being only ableto chat, send e-mail and show web pages seemed less immersive than what Second Life can offer.
- This event generated over 60 leads. We will pass on the contact information to the appropriate sales team.

It's Tuesday, which means IBM makes its announcements. We had several for the IBM System Storage product line. Here's a quick recap.
- Disk Systems
The IBM System Storage DS3000 now offers DC power models.New DC powered models of the DS3200, DS3400, and EXP3000 are well suited for Telco industry environments, as theseare NEBS and ETSI compliant and are powered by an industry standard 48 volt DC power source.
Also, the IBM System Storage N series now supports750GB SATA drives available for the EXN1000 drawer.
- Tape Systems
IBM Virtualization Engine TS7740now supports 3-cluster grids. Unlike 3-way replication on disk mirroring, such as IBM Metro/Global Mirror for the DS8000 that enforces a primary, secondary and tertiary copy, the grid implementation of TS7740 tape virtualization allows for any-to-any mirroring. Existing standalone TS7740 clusters can be converted to grid-enabled. A "Copy Export" feature allows virtual tapes to be exported onto physical tape. And in keeping with our theme of "enabling business flexibility", performance throughput can now be purchased in 100 MB/sec increments, up to 600 MB/sec, to match your workload bandwidth requirements.
The IBM System Storage TS1120drives installed in the IBM System Storage™ TS3400 Tape Library can now be attached to System z platforms using the IBM System Storage™ TS1120 Tape Controller. Before this, the TS3400 could only be attached to UNIX, Windows and Linux systems.
The IBM System StorageTS2230 Express is offered as an external stand-alone or rack-mountable unit. This model incorporates the new LTO IBM Ultrium 3 Serial Attached SCSI (SAS) Half-High Tape Drive, and a 3 Gbps single port SAS interface for a connection to a wide spectrum of distributed system servers that support Microsoft Windows and Linux systems.
- Storage Networking
IBM has added theCisco MDS 9124 for IBM System Storageentry-level fabric switch as an Express offering and part of the IBM Express Advantage Program. Express offerings are specifically created for mid-market companies and are well suited for workgroup storage applications like e-mail serving, collaborative databases and web serving. They bring enterprise-class performance, scalability and features to small and medium-sized companies and are easy to use, highly scalable, and cost-effective.This will make it easier for IBM Business Partners to provide fabric switch connectivity for:
- Storage consolidation solutions with IBM System Storage™ DS4000 Express disk arrays, especially the DS4700 Express.
- Backup / restore solutions with IBM System Storage™ TS3000 Tape Libraries, such as the TS3200.
- Archive and Retention
Ordering large configurations of the IBM System Storage Grid Access Manager just got a lot easier.New features enable configurations greater than 500 TB to be submitted as a single order. No change in the actualproduct, just an improvement in the ordering process.
For System p and System i servers, the IBM 3996 Optical library now supports Gen 2 60GB optical cartridges. These can be read/write or WORM cartridges.
I'm off to Denver, Colorado this week. I hope it is cooler there than it is down here in Tucson, Arizona.

Continuing my coverage of the [IBM Storage Innovation Executive Summit], that occurred May 9 in New York City, this is my third in a series of blog posts on this event.
During lunch, people were able to take a look at our solutions. Here are Dan Thompson and Brett Cooper striking a pose.
- Hyper-Efficient Backup and Recovery
The afternoon was kicked off by Dr. Daniel Sabbah, IBM General Manager of Tivoli software. He started with some shocking statistics: 42 percent of small companies have experienced data loss, 32 percent have lost data forever. IBM has a solution that offers "Unified Recovery Management". This involves a combination of periodic backups, frequent snapshots, and remote mirroring.
IBM Tivoli Storage Manager (TSM) was introduced in 1993, and was the first backup software solution to support backup to disk storage pools. Today, TSM is now also part of Cloud Computing services, including IBM Information Protection Services. IBM announced today a new bundle called IBM Storwize Rapid Application Backup, which combines IBM Storwize V7000 midrange disk system, Tivoli FlashCopy Manager, implementation services, with a full three-year hardware and software warranty. This could be used, for example, to protect a Microsoft Exchange email system with 9000 mailboxes.
IBM also announced that its TS7600 ProtecTIER data deduplication solutions have been enhanced to support many-to-many bi-direction remote mirroring. Last year, University of Pittsburgh Medical Center (UPMC) reported that they were average 24x data deduplication factor in their environment using IBM ProtecTIER.
"You are out of your mind if you think you can live without tape!"
-- Dick Crosby, Director of System Administration, Estes
The new IBM TS1140 enterprise class tape drive process 2.3 TB per hour, and provides a density of 1.2 PB per square foot. The new 3599 tape media can hold 4TB of data uncompressed, which could hold up to 10TB at a 2.5x compression ratio.
The United States Golfers Association [USGA] uses IBM's backup cloud, which manages over 100PB of data from 750 locations across five continents.
- Customer Testimonial - Graybar
Randy Miller, Manager of Technical System Administration at Graybar, provided the next client testimonial. Graybar is an employee-owned company focused on supply-chain management, serving as a distributor for electical, lighting, security, power and cooling equipment.
Their problem was that they had 240 different locations, and expecting local staff to handle tape backups was not working out well. They centralized their backups to their main data center. In the event that a system fails in one of their many remote locations, they can rebuild a new machine at their main data center across high-speed LAN, and then ship overnight to the remote location. The result, the remote location has a system up and running by 10:30am, faster than they would have had from local staff trying to figure out how to recover from tape. In effect, Graybar had implemented a "private cloud" for backup in the 1990s, long before the concept was "cool" or "popular".
In 2001, they had an 18TB SAP ERP application data repository. To back this up, they took it down for 1 minute per day, six days a week, and 15 minutes down on Sundays. The result was less than 99.8 percent availability. To fix this, they switched to XIV, and use Snapshots that are non-disruptive and do not impact application performance.
Over 85 percent of the servers at Graybar are virtualized.
Their next challenge is Disaster Recovery. Currently, they have two datacenters, one in St. Louis and the other in Kansas City. However, in the aftermath of Japan's earthquakes, they realize there is a nuclear power plan between their two locations, so a single incident could impact both data centers. They are working with IBM, their trusted advisors, to investigate a three-site solution.
This week, May 15-22, I am in Auckland, New Zealand teaching IBM Storage Top Gun sales class. Next week, I will be in Sydney, Australia.

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:
- Steve Grillo
- 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
- Eric Buckley
- IBM System Storage TS series, focusing on recent TS2230, TS3400 and TS7700 tape system announcements
- Pete Danforth
- IBM storage networking, focusing on recent IBM SAN256B director blade announcements
(you can read more about these products here:July 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.

Forrester Research has a paper that discusses how Storage Providers Are Divided Into Generalists And Specialists
. The studyfocuses on the buying behaviour of enterprises in North America. Here is an excerpt of their executive summary:
To get beyond the simple statistics of vendor popularity, we looked at the number and combinations of vendors with which enterprises work. Many were customers of one or two storage providers, but the rest were customers of up to six storage providers. More than one-third were customers of systems vendors only, bypassing storage specialists.
Comparisons between solutions vendors and storage component vendors are not new. One could argue that this can be compared to supermarkets and specialty shops.
- Supermarkets offer everything you need to prepare a meal. You can buy your meat, bread, cheese,and extras all with one-stop shopping. In a sense, IBM, HP, Sun and Dell are offering this to clients who prefer this approach. Not surprisingly, the two leaders in overall storage hardware,IBM and HP, are also the two best to offer a complete set of software, services, servers and storage.
This is especially true for small and medium sized businesses (SMB). The Register writesIBM and HP the most loved x86 server vendors of all, beating out other solution providers Dell and Sun.
IBM and HP are also the leaders in tape.While Forrester reports that many large enterprises in North America prefer to buy diskfrom storage specialists, others have found that customers prefer to buy their tape from solution providers. Recently, Byte and Switch reports thatLTO Hits New Milestones,where the LTO consortium (IBM, HP, and Quantum) have collectively shipped over 2 million LTO tape drives, and over 80 million LTO tape cartridges. Perhaps this is because tape is part of an overallbackup, archive or space management solution, and customers trust a solution vendor overa storage specialist.
Where possible, IBM brings synergy between its servers and storage. For example, we justannounced the IBM BladeCenter Boot Disk System, a 2U high unit that supports up to 28 blade servers, ideal for applications running under Windows or Linux, and helping to reduce the energy consumption for thoseinterested in a "Green" data center.
- Specialty shops
- Some people prefer buying their meat at the slaughterhouse, bread at the French pastry shop, andso on. Storage specialists focus on just storage, leaving the rest of the solution, like servers,to be purchased separately from someone else. Storage vendors like NetApp, EMC, HDS and othersoffer storage components to customers that like to do their own "system integration", or to thosethat are large enough to hire their own "systems integrator".
Storage specialists recognize that not everybody is a "specialty shop" shopper.HDS has done well selling their disk through solution vendorslike HP and Sun. EMC sells its gear through solution vendor Dell.
Interestingly, I have met clients who prefer to buy IBM System Storage N series from IBM, becauseIBM is a solution vendor, and others that prefer to buy comparable NetApp equipment directly fromNetApp, because they are a storage component vendor.
I mostly buy my groceries at a supermarket, buthave, on occasion, bought something from the local butcher, baker or candlestick maker. And if you are ever in Tucson, you might be able to find Mexican tamalessold by a complete stranger standing outside of a Walgreens pharmacy, the ultimate extreme of specialization. You can get a dozen tamales for tenbucks, and in my experience they are usually quite good. Theoretically, if you get sick, or they don't taste right, you have no recourse, and will probably never see that stranger again to complain to.(And no, before I get flamed, I am not implying any major vendor mentioned above is like this tamale vendor)
Of course, nothing is starkly black and white, and comparisons like this are just to help provide context and perspective,but if you are looking to have a complete IT solutionthat works, from software and servers to storage and financing, come to the vendor you can trust, IBM.

Well it's Tuesday, and ["election day"
] here in the USA, and again IBM has more announcements.
IBM announced [IBM Tivoli Key Lifecycle Manager v1.0] (TKLM) to manage encryption keys. This provides a graphical interface to manage encryption keys, including retention criteria when sharing keys with other companies.
TKLM is supported on AIX, Solaris, Windows, Red Hat and SUSE Linux. IBM plans to offer TKLM forz/OS in 2009. TKLM can be used with Firefox or Internet Explorer web browser. This will include the Encryption Key Manager (EKM) that IBM offered initially to support encryption keys for the TS1120, TS1130, and LTO-4 drives.
While this is needed today for tape, IBM positions this software to also manage the encryption keys for "Full Drive Encryption" (FDE) disk drive modules (DDM) in IBM disk systems in 2009.
Tomorrow, I'll start my long-overdue vacation!

For those of us in the northern hemisphere, yesterday was this year's Winter Solstice
, representingthe shortest amount of daylight between sunrise and sunset. So today, I thought I would blog on my thoughtsof managing scarcity.
Earlier in my career, I had the pleasure to serve as "administrative assistant" to Nora Denzel for the week at a storage conference. My job was to make her look good at the conference, which if you know Nora, doesn't take much. Later, she left IBM to work at HP, and I gotto hear her speak at a conference, and the one thing that I remember most was her statement that thewhole point of "management" was to manage scarcity, as in not enough money in the budget,not enough people to implement change, or not enough resources to accomplish a task.(Nora, I have no idea where you are today, so if you are reading this, send me a note).
Of course, the flip-side to this is that resources that are in abundance are generallytaken for granted. Priorities are focused on what is most scarce. Let's examine some of theresources involved in an IT storage environment:
- Capacity - while everyone complains that they are "running out of space", the truth is that most external disk attached to Linux, UNIX, or Windows systems contain only 20-40% data. Many years ago, I visitedan insurance company to talk about a new product called IBM Tivoli Storage Manager. This company had 7TB of disk on their mainframe,and another 7TB of disk scattered on various UNIX and Windows machines. In the room were TWO storage admins for
the mainframe, and 45 storage admins for the distributed systems. My first question was "why so many people forthe mainframe, certainly one of you could manage all of it yourself, perhaps on Wednesday afternoons?" Their response was that they acted as eachother's backup, in case one goes on vacation for two weeks. My follow-up question to the rest of the audience was:"When was the last time you took two weeks vacation?" Mainframes fill their disk and tape storage comfortablyat over 80-90% full of data, primarily because they have a more mature, robust set of management software, likeDFSMS.
- Labor - by this I mean skilled labor able to manage storage for a corporation. Some companies I have visitedkeep their new-hires off production systems for the first two years, working only on test or development systemsonly until then. Of course, labor is more expensive in some countries than others. Last year, I was doing a whiteboard session on-site for a client in China, and the last dry-erase pen ran out of ink. I asked for another pen, and they instead sent someone to go re-fill it. I asked wouldn't it be cheaper just to buy another pen, and they said "No, labor is cheap, but ink is expensive." Despite this, China does complain that there is a shortage of askilled IT labor force, so if you are looking for a job, start learning Mandarin.
- Power and Cooling - Most data centers are located on raised floors, with large trunks of electrical power and hugeair conditioning systems to deal with all the heat generated from each machine. I have visited the data centers ofclients that are forced now to make decisions on storage based on power and cooling consumption, because the coststo upgrade their aging buildings are too high. Leading the charge is IBM, with technology advancements in chips, cards, and complete systems that use less power, and generate less heat. While energy is still fairly cheap in the grand scheme of things, fears ofGlobal Warmingand declining oil supplies, the costs ofpower and cooling have gotten some news lately. In 1956, Hubbert predicted US would reach peak oil supplies by1965-1970 (it happened in 1971), and this year Simmonsestimated that world-wide oil production began its decline already in 2005. Smart companies like Google have movedtheir server farms to places like Oregon in the Pacific Northwest for cheaper hydroelectric power.
- Bandwidth - Last year IBM introduced 4Gbps Fibre Channel and FICON SAN networking gear, along with the servers and storage needed to complete the solution. 4Gbps equates to about 400 MB/sec in data throughput. By comparison, iSCSI is typically run on 1Gbps Ethernet, but has so much overheads that you only get abour 80 MB/sec. Next year, we may see both 8 Gbps SAN, and 10 GbE iSCSI, to provide 800 MB/sec throughputs. My experience is that the SAN is not the bottleneck, instead people run out of bandwidth at the server or storage end first. They may not have a million dollars to buy the fastest IBM System p5 servers, or may not have enough host adapters at the storage system end.
- Floorspace - I end with floorspace because it reminds me that many "shortages" are temporary or artificially created. Floorspace is only in short supply because you don't want to knock down a wall, or build a new building, to handle your additional storage requirements.In 1997, Tihamer Toth-Fejel wrote an article for the National Space Society newsletter that estimated that ...Everybody on Earth could live comfortably in the USA on only 15% of our land area, with a population density between that of Chicago and San Francisco. Using agricultural yields attained widely now, the rest of the U.S. would be sufficient to grow enough food for everyone. The rest of the planet, 93.7% of it, would be completely empty.Of course, back in 1997 the world population was only 5.9 billion, and this year it is over 6.5 billion.
This last point brings me back to the concept of food, and I am not talking about doughnuts in the conference room, or pizza while making year-end storage upgrades. I'm talking aboutthe food you work so hard to provide for yourself and your family. The folks at Oxfam came up with a simpleanalogy. If 20 people sit down at your table, representing the world’s population:
- 3 would be served a gourmet, multi-course meal, while sitting at decorated table and a cushioned chair.
- 5 would eat rice and beans with a fork and sit on a simple cushion
- 12 would wait in line to receive a small portion of rice that they would eat with their hands while sitting on the floor.
So for those of you planning a special meal next Monday, be thankful you are one of the lucky three, and hopefulthat IBM will continue to lead the IT industry to help out the other seventeen.
Happy Winter Solstice!

I've only had this blog since Sep. 1, and already it is listed in the Data Storage Bloggers wiki list.
In last week's System Storage Portfolio Top Gun class in Dallas, some of the students were not familiarwith Really Simple Syndication (RSS). For the uninitiated, this can be intimidating.I thought a quick overview of what I've done might help:
- Chose a "feed reader". I chose Bloglines but there are many others.
- Use Technorati to search other blogs for keywords or phrases I am looking for.
- When I find a blog that I like to continue tracking, I "add" it to my subscription list on bloglines. Just hit "add" and copy the URL of the blog you want to track. Bloglines will figure out the RSS keywords required.I track eight blogs at the momemnt, but some people with lots of time on their hands track 20 or more. It is easy to unsubscribe, so don't be afraid to try some out for a few days.
- Since I was actually going to run a blog of my own, I read a few books on the topic. One I recommend is "Naked Conversations" by Robert Scoble and Shel Israel, both experienced bloggers.
- Finally, I am not big on spell checking, but most places have the option to preview your post or comment before it actually gets posted, which is not a bad idea if you use any HTML tags.
For a quick taste of blogging, consider using Data Storage Blogger Feed Reader. This has a lot of blogs on the topic of storage, already added and categorized for your convenience, ready for your perusal.
I am sure there are many other ways to enjoy the Blogosphere, but this works for me.[Read More]
Continuing my two-part series on this week's announcements, I presentIBM's latest for tape and storage software.
- IBM TS7650 and TS7650G ProtecTIER deduplication
In addition to the [TS7650G gateway model] new [Enterprise Edition V2 software], IBM announced four new [TS7650 appliance models] for a complete, integrated solution. The fourconfigurations include the controller and disk:
- 7TB, single controller
- 18TB, single controller
- 36TB, single controller
- 36TB, dual controller in clustered configuration
These disk capacities can have up to 25x times their effective capacity with IBM's HyperFactorin-line deduplication capability. So the smallest 7TB model could be as effective as 175TB of traditionaldisk storage.
- IBM Tivoli Storage Manager (TSM) v6
After years and years in development, IBM announces[TSM v6]. Here's a quick summary of the key features:
- DB2 instead of an internal database
For years, people have complained that IBM used its own internal relational database. This was becausewhen TSM was first launched back in 1993, the DB2 did not have all the features on all of the various server platforms that TSM needed. Today, DB2is the leading relational database on all the key platforms that TSM server runs on, and therefore good enough for use within Tivoli Storage Manager. If you don't already have DB2, it is included for use with TSM v6.1 at no additional charge. Do you have to become a DB2 expert to use TSM? No! The TSM administration commands have been updated to hide all the complexity of DB2 away, behind the scenes. You now just use TSM commands to administer the database,as you did before. IBM will provide conversion utilities to help existing TSM customers migrate to thisnew database environment.
- Better Operational Reporting
Another big complaint was that TSM had fixed reporting, and administrators that wanted customized reportsoften had to resort to purchasing third party products. With the change over to DB2, TSM now enables youto create your own reports using Eclipse's Business Intelligence and Reporting Tools[BIRT]! If you haven't used BIRT, you can downloada free open source copy and start playing around with its capabilities. This is combined with a revamped GUI that provides a customizable dashboard using IBM's Integrated Solutions Console (ISC)infrastructure.
- Software-based Deduplication
Lastly, IBM has incorporated deduplication capability within the TSM v6.1 software for its own diskstorage pools. This is done in a post-process manner so as to dedupe all of your legacy backup dataas well, not just the new stuff, without impacting the current TSM server performance.
At this point, you might be thinking "Wait, what about IBM TS7650 ProtecTIER deduplication?" which is really two questions.
- Can I use TSM v6.1 with IBM TS7650 ProtecTIER?
Yes, however since TSM progressive incremental method is vastly more efficientthan other backup products like Veritas NetBackup or EMC Legato NetWorker, the TS7650 may only get 10x reductionof TSM backups, versus up to 25x with full-backups-every-night backup schemes. TSM only dedupes itsdisk storage pools, so it won't dedupe data directed at tape systems like the TS7650 or othertape libraries. This avoids the "double dedupe" concern.
- When should I use TSM's software version versus TS7650's hardware deduplication?
This is a positioning question. For now, the cut-over point is about 10TB per night backup processing. If youbackup more than 10TB per night, TS7650 hardware may be the better approach. If you are a smaller customer nowhere near that volume of data, then using TSM v6.1 software deduplication may be a morecost-effective solution. If you start small, and grow beyond 10TB per night, it is easy to bring ina TS7650 into an existing TSM environment and migrate the data over.
- Sub-capacity Licensing
If you run TSM server on a logical partition (LPAR) or virtual guest OS under VMware ESX, Xen or Microsoft'sHyper-V environment, why should you have to license it for the whole box? With TSM v6.1, you nowcan pay for only the amount of processors you use, down to a single core even.If you currently run TSM v5 on z/OS, you can migrate over to TSM v6.1 server for Linux on System z totake advantage of cost savings using IFL engines.
- IBM Tivoli Key Lifecycle Manager (TKLM) v1.0
Don't let the "v1.0" scare you, this is the successor to IBM's Encryption Key Manager (EKM) that hasthousands of clients using today with IBM encrypting tape drives. The new TKLM adds support for full disk encryption (FDE) drives--like those for the DS8000 I mentioned in [yesterday's post]--as well as new features to support key rotation for compliance and business controls.
- IBM Tivoli Storage Productivity Center
Last, but not least, we have IBM Tivoli Storage Productivity Center [TSPC]. No, that is not a typo. IBM is renaming IBM TotalStorage Productivity Center to Tivoli Storage Productivity Center toavoid trademark conflicts with the [Professional Golfer's Association].
This is not just renaming existing product. Here some key improvements:
- TSPC brings back together Productivity Center Standard Edition (Disk, Tape, SAN and Data) with Productivity Center for Replication, which were separate at birth a few years ago.
- TSPC adds support for IBM's Storage Enterprise Resource Planner[SERP] from theNovusCG acquisition.
- End-to-end view for EMC storage devices connected to supported servers via EMC Powerpath multipathing driver. As customers switch away from EMC Control Center over to IBM's Productivity Center, IBM can continue to provide support for existing EMC gear.
Of course, IBM will still offer IBM System Storage Productivity Center[SSPC] which is a piece of hardware pre-installed with Productivity Center software.
Hopefully, you can now see why I had to split up all these announcements into separate posts acrossmultiple days!
