This week, I am in beautiful Sao Paulo, Brazil, teaching Top Gun class to IBM Business Partners and sales reps. Traditionally, we have "Tape Thursday" where we focus on our tape systems, from tape drives, to physical and virtual tape libraries. IBM is the number #1 tape vendor, and has been for the past eight years.
(The alliteration doesn't translate well here in Brazil. The Portuguese word for tape is "fita", and Thursday here is "quinta-feira", but "fita-quinta-feira" just doesn't have the same ring to it.)
In the class, we discussed how to handle common misperceptions and myths about tape. Here are a few examples:
- Myth 1: Tape processing is manually intensive
In my July 2007 blog post [Times a Million], I coined the phrase "Laptop Mentality" to describe the problem most people have dealing with data center decisions. Many folks extend linearly their experiences using their PCs, workstations or laptops to apply to the data center, unable to comprehend large numbers or solutions that take advantage of the economies of scale.
For many, the only experience dealing with tape was manual. In the 1980s, we made "mix tapes" on little cassettes, and in the 1990s we recorded our favorite television shows on VHS tapes in the VCR. Today, we have playlists on flash or disk-based music players, and record TV shows on disk-based video recorders like Tivo. The conclusion is that tapes are manual, and disk are not.
Manual processing of tapes ended in 1987, with the introduction of a silo-like tape library from StorageTek. IBM quickly responded with its own IBM 3495 Tape Library Data Server in 1992. Today, clients have many tape automation choices, from the smallest IBM TS2900 Tape Autoloader that has one drive and nine cartridges, all the way to the largest IBM TS3500 multiple-library shuttle complex that can hold exabytes of data. These tape automation systems eliminate most of the manual handling of cartridges in day-to-day operations.
- Myth 2: Tape media is less reliable than disk media
For any storage media to be unreliable is to return the wrong information that is different than what was originally stored. There are only two ways for this to happen: if you write a "zero" but read back a "one", or write a "one" and read a "zero". This is called a bit error. Every storage media has a "bit error rate" that is the average likelihood for some large amount of data written.
According to the latest [LTO Bit Error rates, 2012 March], today's tape expects only 1 bit error per 10E17 bits written (about 100 Petabytes). This is 10 times more reliable than Enterprise SAS disk (1 bit per 10E16), and 100 times more reliable than Enterprise-class SATA disk (1 bit per 10E15).
Tape is the media used in "black boxes" for airplanes. When an airplane crashes, the black box is retrieved and used to investigate the causes of the crash. In 1986, the Space Shuttle Challenger exploded 73 seconds after take-off. The tapes in the black box sat on the ocean floor for six weeks before being recovered. Amazingly, IBM was able to successfully restore [90 percent of the block data, and 100 percent of voice data].
- Myth 3: Most tape restores fail
Why do people still believe that most tape restores fail? Curtis Preston, on his Backup Central blog, has a great post [Gartner Never Said 71 percent of Tape Restores Fail].
Analysts are quite upset when they are quoted out of context, but in this case, Gartner never said anything closely similar to this. Nor did the other analysts that Curtis investigated for similar claims. What Garnter did say was that disk provides an attractive alternative storage media for backup which can increase the performance of the recovery process.
Back in the 1990s, Savur Rao and I developed a patent to help backup DB2 for z/OS by using the FlashCopy feature of IBM's high-end disk system. The software method to coordinate the FlashCopy snapshots with the database application and maintain multiple versions was implemented in the DFSMShsm component of DFSMS. A few years later, this was part of a set of patents IBM cross-licensed to Microsoft for them to implement a similar software for Windows called Data Protection Manager (DPM). IBM has since introduced its own version for distributed systems called IBM Tivoli FlashCopy Manager that runs not just on Windows, but also AIX, Linux, HP-UX and Solaris operating systems.
Curtis suspects the "71 percent" citation may have been propogated by an ambitious product manager of Microsoft's Data Protection Manager, back in 2006, perhaps to help drive up business to their new disk-based backup product. Certainly, Microsoft was not the only vendor to disparage tape in this manner.
A few years ago, an [EMC failure brought down the State of Virginia] due to not just a component failure it its production disk system, but then made it worse by failing to recover from the disk-based remote mirror copy. Fortunately, the data was able to be restored from tape over the next four days. If you wonder why nobody at EMC says "Tape is Dead" anymore, perhaps it is because tape saved their butts that week.
(FTC Disclosure: I work for IBM and this post can be considered a paid, celebrity endorsement for all of the IBM tape and software products mentioned on this post. I own shares of stock in both IBM and Google, and use Google's Gmail for my personal email, as well as many other Google services. While IBM, Google and Microsoft can be considered competitors to each other in some areas, IBM has working relationships with both companies on various projects. References in this post to other companies like EMC are merely to provide illustrative examples only, based on publicly available information. IBM is part of the Linear Tape Open (LTO) consortium.)
Last year, Google lost the email data for half a million Gmail accounts due to a software error. Once again, tape came to the rescue, with [Google restoring lost Gmail data from tape backups].
- Myth 4: Vendors and Manufacturers are no longer investing in tape technology
IBM and others are still investing Research and Development (R&D) dollars to improve tape technology. What people don't realize is that much of the R&D spent on magnetic media can be applied across both disk and tape, such as IBM's development of the Giant Magnetoresistance read/write head, or [GMR] for short.
Most recently, IBM made another major advancement with tape with the introduction of the Linear Tape File Systems (LTFS). This allows greater portability to share data between users, and between companies, but treating tape cartridges much like USB memory sticks or pen drives. You can read more in my post [IBM and Fox win an Emmy for LTFS technology]!
Next month, IBM celebrates the 60th anniversary for tape. It is good to see that tape continues to be a vibrant part of the IT industry, and to IBM's storage business!

Well, it feels like Tuesday and you know what that means... "IBM Announcement Day!" Actually, today is Wednesday, but since Monday was Memorial Day holiday here in the USA, my week is day-shifted. Yesterday, IBM announced its latest IBM FlashCopy Manager v2.2 release. Fellow blogger, Del Hoobler (IBM) has also posted something on this out atthe [Tivoli Storage Blog].
IBM FlashCopy Manager replaces two previous products. One was called Tivoli Storage Manager for Copy Services, the other was called Tivoli Storage Manager for Advanced Copy Services. To say people were confused between these two was an understatement, the first was for Windows, and the second was for UNIX and Linux operating systems. The solution? A new product that replaces both of these former products to support Windows, UNIX and Linux! Thus, IBM FlashCopy Manager was born. I introduced this product back in 2009 in my post [New DS8700 and other announcements].
IBM Tivoli Storage FlashCopy Manager provides what most people with "N series SnapManager envy" are looking for: application-aware point-in-time copies. This product takes advantage of the underlying point-in-time interfaces available on various disk storage systems:
- FlashCopy on the DS8000 and SAN Volume Controller (SVC)
- Snapshot on the XIV storage system
- Volume Shadow Copy Services (VSS) interface on the DS3000, DS4000, DS5000 and non-IBM gear that supports this Microsoft Windows protocol
For Windows, IBM FlashCopy Manager can coordinate the backup of Microsoft Exchange and SQL Server. The new version 2.2 adds support for Exchange 2010 and SQL Server 2008 R2. This includes the ability to recover an individual mailbox or mail item from an Exchange backup. The data can be recovered directly to an Exchange server, or to a PST file.
For UNIX and Linux, IBM FlashCopy Manager can coordinate the backup of DB2, SAP and Oracle databases. Version 2.2 adds support specific Linux and Solaris operating systems, and provides a new capability for database cloning. Basically, database cloning restores a database under a new name with all the appropriate changes to allow its use for other purposes, like development, test or education training. A new "fcmcli" command line interface allows IBM FlashCopy Manager to be used for custom applications or file systems.
A common misperception is that IBM FlashCopy Manager requires IBM Tivoli Storage Manager backup software to function. That is not true. You have two options:
- Stand-alone Mode
In Stand-alone mode, it's just you, the application, IBM FlashCopy Manager and your disk system. IBM FlashCopy Manager coordinates the point-in-time copies, maintains the correct number of versions, and allows you to backup and restore directly disk-to-disk.
- Unified Recovery Management with Tivoli Storage Manager
Of course, the risk with relying only on point-in-time copies is that in most cases, they are on the same disk system as the original data. The exception being virtual disks from the SAN Volume Controller. IBM FlashCopy Manager can be combined with IBM Tivoli Storage Manager so that the point-in-time copies can be copied off to a local or remote TSM server, so that if the disk system that contains both the source and the point-in-time copies fails, you have a backup copy from TSM. In this approach, you can still restore from the point-in-time copies, but you can also restore from the TSM backups as well.
IBM FlashCopy Manager is an excellent platform to connect application-aware fucntionality with hardware-based copy services.

It's Tuesday, and that means more IBM announcements!
I haven't even finished blogging about all the other stuff that got announced last week, and here we are with more announcements. Since IBM's big [Pulse 2010 Conference] is next week, I thought I would cover this week's announcement on Tivoli Storage Manager (TSM) v6.2 release. Here are the highlights:
- Client-Side Data Deduplication
This is sometimes referred to as "source-side" deduplication, as storage admins can get confused on which servers are clients in a TSM client-server deployment. The idea is to identify duplicates at the TSM client node, before sending to the TSM server. This is done at the block level, so even files that are similar but not identical, such as slight variations from a master copy, can benefit. The dedupe process is based on a shared index across all clients, and the TSM server, so if you have a file that is similar to a file on a different node, the duplicate blocks that are identical in both would be deduplicated.
This feature is available for both backup and archive data, and can also be useful for archives using the IBM System Storage Archive Manager (SSAM) v6.2 interface.
- Simplified management of Server virtualization
TSM 6.2 improves its support of VMware guests by adding auto-discovery. Now, when you spontaneously create a new virtual machine OS guest image, you won't have to tell TSM, it will discover this automatically! TSM's legendary support of VMware Consolidated Backup (VCB) now eliminates the manual process of keeping track of guest images. TSM also added support of the Vstorage API for file level backup and recovery.
While IBM is the #1 reseller of VMware, we also support other forms of server virtualization. In this release, IBM adds support for Microsoft Hyper-V, including support using Microsoft's Volume Shadow Copy Services (VSS).
- Automated Client Deployment
Do you have clients at all different levels of TSM backup-archive client code deployed all over the place? TSM v6.2 can upgrade these clients up to the latest client level automatically, using push technology, from any client running v5.4 and above. This can be scheduled so that only certain clients are upgraded at a time.
- Simultaneous Background Tasks
The TSM server has many background administrative tasks:
- Migration of data from one storage pool to another, based on policies, such as moving backups and archives on a disk pool over to a tape pools to make room for new incoming data.
- Storage pool backup, typically data on a disk pool is copied to a tape pool to be kept off-site.
- Copy active data. In TSM terminology, if you have multiple backup versions, the most recent version is called the active version, and the older versions are called inactive. TSM can copy just the active versions to a separate, smaller disk pool.
In previous releases, these were done one at a time, so it could make for a long service window. With TSM v6.2, these three tasks are now run simultaneously, in parallel, so that they all get done in less time, greatly reducing the server maintenance window, and freeing up tape drives for incoming backup and archive data. Often, the same file on a disk pool is going to be processed by two or more of these scheduled tasks, so it makes sense to read it once and do all the copies and migrations at one time while the data is in buffer memory.
- Enhanced Security during Data Transmission
Previous releases of TSM offered secure in-flight transmission of data for Windows and AIX clients. This security uses Secure Socket Layer (SSL) with 256-bit AES encryption. With TSM v6.2, this feature is expanded to support Linux, HP-UX and Solaris.
- Improved support for Enterprise Resource Planning (ERP) applications
I remember back when we used to call these TDPs (Tivoli Data Protectors). TSM for ERP allows backup of ERP applications, seemlessly integrating with database-specific tools like IBM DB2, Oracle RMAN, and SAP BR*Tools. This allows one-to-many and many-to-one configurations between SAP servers and TSM servers. In other words, you can have one SAP server backup to several TSM servers, or several SAP servers backup to a single TSM server. This is done by splitting up data bases into "sub-database objects", and then process each object separately. This can be extremely helpful if you have databases over 1TB in size. In the event that backing up an object fails and has to be re-started, it does not impact the backup of the other objects.

Happy Winter Solstice everyone! The Mayan calendar flipped over yesterday, and everything continued as normal.
The next date to watch out for is ... drumroll please ... April 8, 2014. This is the date Microsoft has decided to [drop support for Windows XP].
While many large corporations are actively planning to get off Windows XP, there are still many homes and individuals that are running on this platform.
When [Windows XP] was introduced in 2001, it could support systems with as little as 64MB of RAM. Nowadays, the latest versions of Windows now requires a minimum of 1GB for 32-bit systems, with 2GB or 3GB recommended.
That leaves Windows XP users on older hardware few choices:
- Continue to run Windows XP, but without support (and hope for the best)
- Upgrade their hardware with more RAM (and possibly more disk space) needed to run a newer level of Windows
- Install a different operating system like Linux
- Put the hardware in the recycle bin, and buy a new computer
Here is a personal example. A long time ago, I gave my sister a Thinkpad R31 laptop so that she could work from home. When she got a newer one, she passed this down to her daughter for doing homework. When my neice got a newer one, she passed this old laptop to her grandma.
Grandma is fairly happy with her modern PC running Windows XP. She plays all kinds of games, scans photographs, sends emails, listens to music on iTunes, and even uses Skype to talk to relatives. Her problem is that this PC is located upstairs, in her bedroom, and she wanted something portable that she could play music downstairs when she is playing cards with her friends.
"Why not use the laptop you have?" I asked. Her response: "It runs very slow. Perhaps it has a virus. Can you fix that?" I was up for the challenge, so I agreed.
(The Challenge: Update the Thinkpad R31 so that grandma can simply turn it on, launch iTunes or similar application, and just press a "play" button to listen to her music. It will be plugged in to an electrical outlet wherever she takes it, and she already has her collection of MP3 music files. My hope is to have something that is (a) simple to use, (b) starts up quickly, and (c) will not require a lot of on-going maintenance issues.)
Here are the relevant specifications of the Thinkpad R31 laptop:
|CPU||Intel Celeron 1.13GHz Pentium-III|
|Display||13.3-inch TFT, 1024x768 XGA|
|Memory (RAM)||384 MB @133MHz, upgradeable only to 1GB|
|Disk storage||20.0 GB|
|Optical Drive||CD-ROM drive|
|BIOS boot options||Hard drive or CD-ROM only|
|External attachment||2 USB ports, but no USB boot option|
|Network||Wired 10/100 Mbps Ethernet|
56 Kbps Phone modem
The system was pre-installed with Windows XP, but was terribly down-level. I updated to Windows XP SP3 level, downloaded the latest anti-virus signatures, and installed iTunes. A full scan found no viruses. All this software takes up 14GB, leaving less than 6GB for MP3 music files.
The time it took from hitting the "Power-on" button to hearing the first note of music was over 14 minutes! Unacceptable!

This week, I am in Taipei, teaching Top Gun class. There was concern that another typhoon would hit the island of Taiwan later this week, but it looks like it is now headed for Hong Kong instead.
Elsewhere in the world, there are several events going on next week, so I thought I would bring them to your attention.
- ECTY - South Africa
Next week, Jerry Kluck, IBM Global Sales Executive for Storage Optimization and Integration Services, will be the keynote speaker at "Edge Comes to You" (ECTY) conference in South Africa. This is a one-day event, similar to the [ECTY event in Moscow, Russia] that I spoke at last June.
Here is the schedule for South Africa next week:
- Monday, August 20, 2012 - Johannesburg
- Wednesday, August 22, 2012 - Cape Town
(I have been to both Jo'burg and Cape Town back in 1994. A month after Apartheid had just ended, I was part of a small group of IBMers sent to re-establish IBM's business operations there. I would have liked to have attended the events next week, not just to hear Jerry speak, but also to see how much the country has changed over the past 18 years, but I could not get a work permit in time.)
If you are interested in attending either of these next week, contact your local IBM Business Partner or sales rep to attend.
- Forrester's Total Economic Impact Study of Virtualized Storage

Back in Februray, my blog post [A Box Full of Floppies] mentioned that I uncovered some diskettes compressed with OS/2 Stacker. Jokingly, I suggested that I may have to stand up an OS/2 machine just to check out what is actually on those floppies. Each floppy contains only three files: README.STC, STACKER.EXE and a hidden STACKVOL.DSK file. The README.STC explains that the disk is compressed by Stacker, a program developed by [Stac Electronics, Inc.]. The STACKER.EXE would not run on Windows XP, Vista or Windows 7. The STACKVOL.DSK is just a huge binary file, like a ZIP file, compressed with [Lempel-Ziv-Stac] algorithm that combines Lempel-Ziv with Huffman coding.
In my follow-up post [Like Sands in an Hourglass], I explained how there are many ways I could have tackled this project. I could either use the Emulation approach and try to build an OS/2 guest image under a hypervisor like VMware, KVM or VirtualBox, or just take the Museum approach and try taking one of my half dozen old machines, wipe it clean and stand up OS/2 on it bare metal. This turned out to be more challenging than I expected. The systems I have that are modern and powerful enough to run hypervisors don't have floppy drives, so I opted for the Museum approach.
(A quick [history of OS/2] might be helpful. IBM and Microsoft jointly developed OS/2 back in 1985. By 1990, Microsoft decided it's own Windows operating system was more popular with the ladies, and decided to break off with IBM. In 1992, IBM release OS/2 version 2.0, touted as "a better DOS than DOS and a better Windows than Windows!" Both parties maintained ownership rights, Microsoft renamed OS/2 to Windows NT. The "NT" stood for New Technology, the basis for all of the enterprise-class Windows servers used today. IBM named its version of OS/2 version 3 and 4 "WARP", with the last version 4.52 released in 2001. In its heyday, OS/2 ran the majority of Automated Teller Machines (ATMs), was used for hardware management consoles (HMC), and was used worldwide to run various Railway systems. After 2001, IBM encouraged people to transition from Windows or OS/2 over to Java and Linux. For those that can't or won't leave OS/2, IBM partnered with Serenity Systems to continue OS/2 under the brand [eComStation].)
Working with an IBM [ThinkCentre 8195-E2U Pentium 4 machine] with 640MB RAM and 80GB hard disk, a CD-rom and one 3.5-inch floppy drive, I first discovered that OS/2 is limited to very small amounts of hard disk. There are limits on [file systems and partition sizes] as well as the infamous [1024-cylinder limit] for bootable operating systems. Having a completely empty drive didn't work, as the size of the disk was too big. Carving out a big partition out of this also failed, as it exceeded the various limits. Each time, it felt the partition table was corrupted because the values were so huge. Even modern Disk Partitioning tools ([SysRescueCD] or [PartedMagic]) didn't work, as these create partitions not recognizable to OS/2.
The next obstacle I knew I would encounter would be device drivers. OS/2 comes as a set of three floppy diskettes and a CD-rom. The bootable installation disk was referred to affectionately as "Disk 0", then Disk 1, then Disk 2. Once all drivers have been loaded into memory, then it can start looking at the CDrom, and continue with the installation. In searching for updated drivers, I came across [Updated OS/2 Warp 4 Installation Diskettes] to address problems with newer display monitors. It also addresses the 8.4GB volume limit.
The updates were in the form of EXE files that only execute in a running DOS or OS/2 environment, expanded onto a floppy diskette. It seemed like [Catch-22], I need a working DOS or OS/2 system to run the update programs to create the diskettes, but need the diskettes to build a working system.
To get around this, I decided to take a "scaffolding" approach. Using DOS 6 bootable floppy, I was able to re-partition the drive with FDISK into two small 1.9GB partitions. I have the full five-floppy IBM DOS 6 set, I hid the first partition for OS/2, and install the DOS 6 GUI on the second partition. I went ahead and added a few new subdirectories: BOOT to hold Grub2, PERSONAL to hold the data I decompress from the floppies, and UTILS to hold additional utilities. This little DOS system worked, and I now have new OS/2 "Disk 1" and "Disk 2" for the installation process.
(If you don't have a full set of DOS installation diskettes, you can make due with "FORMAT C: /S" from a [DOS boot disk], and then just copy over all the files from the boot disk to your C: drive. You won't have a nice DOS GUI, but the command line prompt will be enough to proceed.)
Like DOS, OS/2 expects to be installed on the C: drive. I hid the second partition (DOS), and marked the first partition installable and bootable. The OS/2 installation involves a lot of reboots, and the hard drive is not natively bootable in the intermediate stages. This means having to boot from Disk 0, then putting in Disk 1, then disk 2, before continuing the next phase of the installation. I tried to keep the installation as "Plain Vanilla" as possible.
I had to figure out what to include, and what to exclude, and this involved a lot of trial and error. For example, one of the choices was for "external diskette support". Since I had an "internal diskette drive", I didn't think I needed it. But after a full install, I discovered that it would not read or write floppy diskettes, so it appears that I do indeed need this support.
OS/2 supports two different file systems, FAT16 and the High Performance File System (HPFS). Since my partition was only 1.9GB in size, I chose just to use FAT16. HPFS supported larger disk partitions, longer file names, and faster performance, none of which I need for these purposes.
I thought it would be nice to get TCP/IP networking to work with my Ethernet card. However, after many attempts, I decided against this. I needed to focus on my mission, which was to decompress floppy diskettes. It was amusing to see that OS/2 supported all kinds of networking, including Token Ring, System Management, Remote Access, Mobile Access Services, File and Print.
Once all the options are chosen, OS/2 installation then proceeds to unpack and copy all the programs to the C: drive. During this process, IBM had informational splash screens. Here's one that caught my eye, titled "IBM Means Three Things" that listed three reasons to partner with IBM:
- Providing global solutions for a small planet
- Creating and Applying advanced technologies to improve with which customers run their businesses
- Constantly improving customer service with the products and services we provide
You might wonder how these OS/2 splash screens, written over 10 years ago, can appear almost identical to IBM's current [Smarter Planet] campaign. Actually, it is not that odd. IBM has been keeping to these same core principles since 1911, only the words to describe and promote these core values have changed.
To access both OS/2 and DOS partitions, I installed Grand Unified Bootloader [Grub2] on the DOS partition under C:/BOOT/GRUB directory. However, when I boot OS/2, I cannot see the DOS partition. And when I boot DOS, I cannot see the OS/2 partition. Each operating system thinks its C: drive is the only partition on the system.
Now that I had OS/2 running, I was then able to install Stacker from two floppy diskettes. With this installed, I can compress and decompress data on either the hard disk, or on floppy diskettes. Most of the files were flat text documents and digital photos. After copying the data off the compressed disks onto my hard drive, I now can copy them off to a safe place.
To finish this project, I installed Ubuntu Linux on the remaining 76GB of disk space, which can access both the OS/2 and DOS drives FAT16 file systems natively. This allows me to copy files from OS/2 to DOS or vice versa.
Now that I know what data types are on the diskettes, I determined that I could have decompressed the data in just a few steps:
- Set up a DOS partition on C: drive
- Insert one of the compressed diskettes into the floppy drive
- Copy the STACKER.EXE program from the floppy to the C: drive
- Run "STACKER A:" to decompress the floppy diskette
However, now that I have a working DOS and OS/2 system, I can possibly review the rest of my floppy diskettes, some of which may require running programs natively on OS/2 or DOS. This brings me to an important lesson. If you are going to keep archive data for long-term retention, you need to choose file formats that can be read by current operating systems and programs. Installing older operating systems and programs to access proprietary formats can be quite time-consuming, and may not always be possible or desirable.

Yes, it's Tuesday, and that means more IBM Announcements! A lot was announced today, so I have selected an eclectic mix for your enjoyment.
- Microsoft Windows support on IBM Mainframes
Last year's announcement of the new IBM zEnterprise included the zEnterprise BladeCenter Extention (zBX) which could run POWER7 and x86 operating systems, but managed by the mainframe's overall Unified Resource Manager. Initially, this was intended for AIX and Linux-x86, but today, IBM [announced a statement of general direction to support Microsoft Windows] on the zBX extension by end of this year. Of course, the standard disclaimer applies: All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice. Any reliance on these statements of general direction is at the relying party's sole risk and will not create liability or obligation for IBM.
- New 15K RPM drives for IBM Storwize V7000
Last October, when IBM introduced the Storwize V7000, it offered both large (3.5 inch) and small form factor (2.5 inch) drives. Unfortunately, a few people were upset that there were no 15K RPM drives for the small form factor models. There were SSD and 10K RPM drives, but nothing in between. Today, IBM [announced new 15K RPM drives of 146GB capacity] have been qualified for both the controller and expansion drawers.
- New RVU licensing for IBM Tivoli products
IBM [announced it is changing over to this new RVU licensing model], from the previous PVU license, based on processor value units. What is an RVU? An RVU is a unit of measure by which the program can be licensed. RVU Proofs of Entitlement (PoE) are based on the number of units of a specific resource used or managed by the program. This makes sense, resource management software should be charged by the amount of resources you manage, not the size of the server the software runs on. This change also enables running on server virtualization and live movement of VM guest images from one type of host machine to another.
If you are contemplating a visit to an IBM [Executive Briefing Center], then April and May is a great time to come to Tucson. The weather is ideal here. The cold snap appears to be over, and spring is in the air!

For most of us in the United States, it is cold out there, so you better "bundle up!"
Today, IBM announces the [IBM Storwize Rapid Application Storage] bundle, an integrated solution that improves storage efficiency and application availability. It comes in two offerings:
The "Basic" offering includes a single IBM Storwize V7000 controller enclosure, and three year warranty package that includes software licenses for IBM Tivoli Storage FlashCopy Manager (FCM) and IBM Tivoli Storage Productivity Center for Disk - Midrange Edition (MRE). Planning, configuration and testing services for the software are included and can be performed by either IBM or an IBM Business Partner.
The "Standard" offering allows for multiple IBM Storwize V7000 enclosures, provides three year warranty package for the FCM and MRE software, and includes implementation services for both the hardware and the software components. These services can be performed by IBM or an IBM Business Partner.
Why bundle? Here are the key advantages for these offerings:
- Increased storage utilization! First introduced in 2003, IBM SAN Volume Controller is able to improve storage utilization by 30 percent through virtualization and thin provisioning. IBM Storwize V7000 carries on this tradition. Space-efficient FlashCopy is included in this bundle at no additional charge and can reduce the amount of storage normally required for snapshots by 75 percent or more. IBM Tivoli Storage FlashCopy Manager can manage these FlashCopy targets easily.
- Improved storage administrator productivity! The new IBM Storwize V7000 Graphical User Interface can help improve administrator productivity up to 2 times compared to other midrange disk solutions. The IBM Tivoli Storage Productivity Center for Disk - Midrange Edition provides real-time performance monitoring for faster analysis time.
- Increased application performance! This bundle includes the "Easy Tier" feature at no additional charge. Easy Tier is IBM's implementation of sub-LUN automated tiering between Solid-State Drives (SSD) and spinning disk. Easy Tier can help improve application throughput up to 3 times, and improve response time up to 60 percent. Easy Tier can help meet or exceed application performance levels with its internal "hot spot" analytics.
- Increased application availability! IBM Tivoli Storage FlashCopy Manager provides easy integration with existing applications like SAP, Microsoft Exchange, IBM DB2, Oracle, and Microsoft SQL Server. Reduce application downtime to just seconds with backups and restores using FlashCopy. The built-in online migration feature, included at no additional charge, allows you to seamlessly migrate data from your old disk to the new IBM Storwize V7000.
- Significantly reduced implementation time! This bundle will help you cut implementation time in half, with little or no impact to storage administrator staff. This will help you realize your return on investment (ROI) much sooner.

IBM had its big launch yesterday of the [IBM Storwize V7000 midrange disk system], and already some have discussed IBM's choice of the name. Fellow blogger Stephen Foskett has an excellent post titled
[IBM’s Storwize V7000: 100% SVC; 0% Storwize]. On The Register, Chris Mellor writes [IBM's Midrange Storage Blast - Storwize. But Without Compression]. In his latest [Friday Rant], fellow blogger Chuck Hollis (EMC) feels "the new name is cool, if a bit misleading."
In the spirit of the [HP Product Line Decoder Ring] and [Microsoft Codename Tracker], here is your quick IBM product name decoder ring:
|In English||Protocols||Which company|
|What IBM decided|
to call it
|Intelligent block-level disk array that virtualizes both internal and external disk storage||8 Gbps FCP and 1GbE iSCSI||IBM||IBM Storwize V7000 disk system|
|Real-time compression appliance for files||10GbE/1GbE CIFS and NFS||Storwize, now an IBM company||IBM Real-time Compression STN-6800 appliance|
|1GbE CIFS and NFS||IBM Real-time Compression STN-6500 appliance|
If you think this is the first time a company like IBM has pulled shenanigans with product names like this, think again. Here are a few posts that might refresh your memory:
- In my September 2006 post, [A brand by any other name...] I explain that I started blogging specifically to promote the new "IBM System Storage" product line name, part of the "IBM Systems" brand resulting from merging the "eServer" and "TotalStorage' brands.
- In my January 2007 post, [When Names Change], I explain our naming convention for our disk products, including our DS family, SAN Volume Controller and N series.
- In my February 2008 post, [Getting Off the Island], I cover how the x/p/i/z designations came about for our various IBM server product lines.
But what about acquisitions? When [IBM acquired Lotus Development Corporation], it kept the "Lotus" brand. New products that fit the "collaboration" function were put under the Lotus brand. I think most people can accept this approach.
But have we ever seen an existing product renamed to an acquired name?
In my post January 2009 post
[Congratulations to Ken on your QCC Milestone], I mentioned that my colleague Ken Hannigan worked on an internal project initially called "Workstation Data Save Facility" (WDSF) which was changed to "Data Facility Distributed Storage Manager" (DFDSM), then renamed to "ADSTAR Distributed Storage Manager" (ADSM), and finally renamed to the name it has today: IBM Tivoli Storage Manager (TSM).
Readers reminded me that [IBM acquired Tivoli Systems, Inc.] in 1996, so TSM could not have been an internally developed product. Ha! Wrong! Let's take a quick history lesson on how this came about:
- In the late 1980s, IBM Almaden research had developed a project to backup personal computers and workstations, which they called "Workstation Data Save Facility" or WDSF.
This was turned over to our development team, which immediately discarded the code, and wrote from scratch its replacmeent, called Data Facility Distributed Storage Manager (DFDSM), named similar to the Data Facility products on the mainframe (DFP, DFHSM, DFDSS). As a member of the Data Facility family, DFDSM didn't really fit. The rest processed mainframe data sets, but DFDSM processed Windows and UNIX files. That a version of DFDSM server was available to run on the mainframe was the only connection.
Then, in the early 1990s, there were discussions of possibly splitting IBM into a bunch of smaller "Baby Blues", similar to how [AT&T was split into "Baby Bells"], and how Forbes and Goldman Sachs now want to split Microsoft into [Baby Bills]. IBM considered naming the storage spin-off as ADSTAR, which stood for "Advanced Storage and Retrieval."
Pre-emptively, IBM renamed DFDSM to "ADSTAR Distributed Storage Manager" or ADSM.
- Fortunately, in 1993, IBM brought a new sheriff to town, Lou Gerstner, who quickly squashed any plans to split up IBM. He quickly realized that IBM's core strength was building integrated stacks, combining systems, software and services to solve business problems.
- In 1996, IBM acquired Tivoli Systems, Inc. to expand its "Systems Management" portfolio, and renamed ADSM over to IBM Tivoli Storage Manager, since "storage management" is an essential part of "systems management". Later, IBM TotalStorage Productivity Center would be renamed to "IBM Tivoli Storage Productivity Center."
I participated in five months of painful meetings to figure out what to name our new internally-developed midrange disk system. Since it ran SAN Volume Controller software, I pushed for keeping the SVC designation somehow. We considered DS naming convention, but the new midrange product would not fit between our existing DS5000 and DS6000 numbering scheme. A marketing agency we hired came up with nonsensical names, in the spirit of product names like Celerra, Centera and CLARiiON, using name generators like [Wordoid]. Luckily, in the nick of time, IBM acquired Storwize for its compression technology, and decided that Storwize as a name was way better fit than any of the names we came up with already.
However, the new IBM Storwize V7000 midrange product had nothing in common with the appliances acquired from Storwize, the company, so to avoid confusion, the latter products were renamed to [IBM Real-time Compression]. Fellow blogger Steven Kenniston, the Storage Alchemist from Storwize fame now part of IBM from the acquisition, gives his perspective on this in his post [Storwize – What is in a Name, Really?]. While I am often critical of the names and terms IBM uses, I have to say this last set of naming decisions makes a lot of sense to me and I support it wholeheartedly.

[longer version for IT technical professionals].

In preparation for my [upcoming trip to Australia and New Zealand], I decided to upgrade my smartphone. My service provider T-Mobile offered me the chance to try out any new phone for 14 days for only ten dollar re-stocking fee. For the past 16 months, I have used the Google G1 phone. This is based on a storage-optimized Android operating system, based on open source Linux, with applications processed in a storage-optimized virtual machine called Dalvik, based on open source Java. According to Wikipedia, Android-based phones have #1 market share [outselling both BlackBerry OS and Apple iOS phones]. There are over 70 different companies using Android, driven away from the proprietary interfaces from Apple, BlackBerry and Microsoft.
Since I was already familiar with the Android operating system, I chose the Samsung Galaxy S Vibrant. I liked my G1, but it had only a small amount of internal memory to store applications. The G1 supported an external Micro SDHC card, but this only was used for music and photos. There was no way to install applications on the memory card, so I found myself having to uninstall applications to make room for new ones. By contrast, the Vibrant has 16GB internal memory, plenty of room for all applications, and supports Micro SDHC up to 32GB in size. My model can pre-installed with a 2GB card, of which 1.4GB is consumed by James Cameron's full-length movie Avatar. On the G1, swapping out memory cards was relatively easy. On the Vibrant, you have to take the phone apart to swap out cards, so I won't be doing that very often. I will probably just get a 32GB card and leave it in there permanently.
(FTC disclosure: I work for IBM. IBM has working relationships with Oracle, Google, and lots of other companies. IBM offers its own commercial version of Java related tools. I own stock in IBM, Apple, Google. I have friends and family who work at Microsoft. My review below is based entirely on my own experience of my new Samsung Galaxy S Vibrant phone. Samsung has created different models for different service providers. The T-Mobile Vibrant is an external USB storage device with telephony capabilities, comparable to the AT&T Captivate, Verizon Fascinate, or Sprint Epic 4G. The majority of mobile phones in the world contain IBM technology. This post is not necessarily an endorsement for Samsung over other smartphone manufacturers, nor T-Mobile over other service providers. I provide this information in context of storage optimization, state-of-the-art for smartphones in general, and disputes related to software patents between companies. I hold 19 patents, most of which are software patents.)
When Oracle acquired Sun Microsystems, it inherited stewardship of Java. Java is offered in two flavors. Java Standard Edition (SE) for machines that are planted firmly on or below your desk, and Java Micro Edition (ME) for machines that are carried around. Most Java-based phones limit themselves to Java ME, but Google decided to base its smartphones on the more powerful Java SE, but then optimize for the limited storage and computing resources. These two levels of Java have radically different licensing terms and conditions, so Larry Ellison of Oracle cried foul. On The Register, Gavin Clarke has an excellent article with details of the Oracle-vs-Google complaint. Daniel Dilger opines that Oracle [might kill Google’s Android and software patents all at once]. Fellow blogger Mark Twomey (EMC) on his StorageZilla blog, argues that [it's not about Android phones, but Android everything].
My Vibrant is roughly the size of a half-inch stack of 3x5 index cards in my hand. In my humble opinion, the problem is the grey area between mobile phone and the desktop personal computer. Laptops, netbooks, iPads, tablet computers, eBook readers, and smartphones fall somewhere in between. At what point do you stop licensing Java SE and start licensing Java ME instead?
Let's take a look at all the stuff my new Samsung Vibrant can do, and let you decide for yourself. I have 140 applications installed, which I can access alphabetically. I also have up to seven screens which I can fill with application icons and widgets to simplify access. The screen measures about 4 inches diagonally. Click on each image below to see the full 480x800 resolution.
Each screen has five rows. On my first screen, I have the first two rows related to photography. This includes a camera, camcorder, bar-code scanner and visual search engine (Google Goggles). I am not happy with Flickr Droid app in uploading photos, so I might need to find another app for that. Other reviews I read complain that the Vibrant's camera does not have am LED flash for night time shots, and that there is no forward facing camera to do Skype or FaceTime-style videoconferencing. I think it is fine the way it is. An interesting feature of the camera app is that it uses the volume up/down buttons to zoom in and out.
The next two rows related to books and documents. In addition to both Amazon's Kindle and Barnes and Noble's Nook eBook readers, I have Dropbox to make it easy to transfer files between all my machines, a camera-scanner that generates PDFs, and ThinkFree, which appears to be based on OpenOffice open source software to create, view and edit WORD documents, EXCEL spreadsheets and PowerPoint presentations.
My second screen is for music and video entertainment.
The top row is consumed by a single widget for [Pandora], an internet radio station, not to be confused with the Pandora moon that the movie Avatar is based on. I-heart-radio, Slacker, and Last.fm are other internet radio stations. Be careful when roaming in another country, as the $15-per-MB transfer fees can really add up. While the Galaxy S has a built-in FM radio, T-Mobile has decided to disable this feature in its Vibrant model, in favor of internet-based radio stations.
I am glad the Samsung Vibrant uses the same 3.5mm combo audio jack that I mentioned in my blog post about my
[New ThinkPad T410]. This allows me to use the same headset for both my laptop and my cell phone.
For those who use Microsoft Windows Media Player v10 or above, this phone lets you transfer over your songs, playlists and videos via the USB cable in PMC mode. The TED application shows 18-minute videos of lectures at conferences that focus on Technology, Entertainment and Design. MobiTV offers live streaming of popular Television shows, normally ten dollars monthly, but I got a free 30-day trial in the deal.
Screen 3 is focused on travel. I have a 30-day free trial of GoGo, the new Wi-Fi networks on various airlines. Hopefully, I will get to try this out on my upcoming flights. When GoGo is not available, the Extended Controls widget allows me to turn the phone into "Airplane mode", which would allow me to read eBooks and listen to pre-recorded music and videos stored on my phone. Most of the apps on Android are free, but Extended Controls, shown here in the top row, cost me money but well worth it. With this you can customize different size widgets with all the appropriate setting toggles you want. On this one, I can toggle Wi-Fi, Data transfer, GPS positioning, and Airplane mode.
Google Maps, Google Places and Google Sky Map are all well represented here. I also like TripIt, which is a free Software-as-a-Service for managing your trip itenerary, and syncs up with their online website. Currency and Language translation can help on international travel. The standard Alarm Clock also includes Time Zone conversion as well.
My screen 4 is my central home page. There are four buttons on the bottom of the phone: Menu, Home, Back, and Search. Hit the "Home" button on any screen, and it jumps immediately to Screen 4. From here, I can get to any of the other screens with just swiping my finger across the surface. Therefore, I chose to keep this screen simple.
For meetings, I have a big clock, and an Extended Controls widget to set my phone on silent/vibrate mode, and show my battery status. I put icons here for apps that I might need in a hurry, like Camera, Evernote, or Shazam. For those not familiar with Shazam, it will listen to the microphone for whatever song is playing in the background where you are, and it will identify the song's title and artist.
The "Starred" folder lists those five or so contacts that I have marked with a "star" to be on this short list. From here, I can call or send them an SMS text message.
Screen 5 is for office productivity. I have a 2x2 widget from Astrid to list my to-do items. I have a 1x2 widget showing my last call. My calendar syncs up with my Google calendar online.
The Locale widget allows me to change which on-screen keyboard to use. There is the standard Android keyboard which allows voice-to-text input, the Samsung keyboard that offers [XT9 mode], and the new ["Swype"] keyboard that allows you to write words quickly with squiggles swiped across the keyboard. The Swype is incredible accurate when I am typing in English. When I am communicating in Spanish, it gets in the way, spell-checking when it shouldn't.
Screen 6 is for my social media, news and search facilities. I have HootSuite Lite for managing my Twitter and Facebook posts. For news junkies, NPR, USA Today and CNN all offer mobile versions.
I have a selection of browsers, including Opera Mini 5, and Dolphin Browser HD. The latter offers a variety of special add-ons similar to Firefox on a desktop system. I also have specialty search sites, including the Internet Movie Database (IMDB), Fandango for local movie times, and Dex for local phone listings.
Screen 7 is for system administration. The top row is another "Extended Controls" widget, this time to change between 2G and 3G networks, brightness setting, set the the time-out interval for when the screen should automatically shut off, and a "stay awake" to turn off the screen saver altogether.
I can do some really powerful things here. For example, I have an application to let me use secure shell (ssh) to access our systems at work. I also can "tether" my laptop to my Vibrant, for those few times when Wi-Fi is not available, to let my laptop use the phone's signal as a dial-up modem. It is slower than Wi-Fi, but might be just what I need in a pinch.
The bottom row is the same across all seven screens, which you can customize. I left the bottom row in its original default, with options to make phone calls, look up contacts, and send text messages. The bottom right corner launches a list of all applications alphabetically, to access those not on my seven main screens.
Just in case I switch to a local SIM card while abroad in another country, I asked T-mobile to unlock my phone, which they happily did at no additional charge. For example, while I am in Australia, I can either leave my T-Mobile USA chip in the phone, and pay roaming charges per minute, or I can purchase a SIM chip from a local phone company with pre-paid minutes. This often includes unlimited free incoming calls to a local Australian phone number, and voicemail.
Unlocking the phone to use different SIM cards is different than "jailbreaking", a term that refers to Apple's products. For Android phones, jailbreaking is called "rooting", as the process involves getting "root" user access that you normally don't have. The only reason I have found to have my phone "rooted" was to take these lovely screen shots, using the "Screen Shot It" application. This is another application that I paid for. I used the free trial for a few screenshots first to check it out, liked the results, and bought the application.
So, this new smartphone looks like a keeper. I got a screen protector to avoid scratching, and a two-piece case that snaps around the phone to give it more heft. All my chargers are "Mini USB" for my old G1 phone, and this new Vibrant phone is "Micro USB" instead, so I had to order new ones for my car, my office, and for my iGo (tip A97).
This review is more to focus on the fact that the IT industry is changing, and what was traditionally performed on personal computers are now being done on new handheld devices. Android provides a platform for innovation and healthy competition. Let's all hope Oracle and Google can work out their differences amicably.
