Jon Toigo over at DrunkenData writes in his post[A Wink and a Nod
] about thebenefits of the new IBM System z10 Enterprise Class mainframe. Here's an excerpt about storage:
"The other key point worth making about this scenario is that storage behind a z10 must conform to IBM DASD rules. That means no more BS standards wars between knuckle-draggers in the storage world who continue to mitigate the heterogeneous interoperability and manageability of distributed systems storage using proprietary lock in technologies designed as much to lock in the consumer and lock out the competition as to deliver any real value. That has got to be worth something."
For z/OS and TPF operating systems, disk must support CCW commands over ESCON or FICON connections, or NFS commandsover the Local Area Network. However, most of the workloads that are being ported over from x86 platforms willprobably be running Linux on System z images, and as such Linux supports both CCW and SCSI protocols, the latterover native FCP connections through a Storage Area Network (SAN) or via iSCSI over the Local Area Network. Many SAN directors support both FCP and FICON, and the z10 also supports both 1Gbps and 10Gbps Ethernet, so you may not have to invest in any new networking gear.
The best part is that you may not have to migrate your data. The IBM System Storage SAN Volume Controller is supported for Linux on System z, and with "image mode" you can leave the data in its original format on its original disk array. Many file systems are now supported by Linux, including Windows NTFS with the latest NTFS-3G driver.
If your data is already on NAS storage, such as the IBM System Storage N series disk systems, then the IBM z10can access it directly, from z/OS, z/VM or Linux.
Have lots of LTO tape data? Linux on System z supports LTO as well.
Jon continues his rant with a question about porting Microsoft Windows applications. Here's another excerpt:
"For one, what do we do with all the Microsoft servers. There is no Redmond-sanctioned approach to my knowledge for virtualizing Microsoft SQL Server or Exchange Server in a mainframe partition."
Yes, it is possible to run Windows on a mainframe through emulation, but I feel that's the wrong approach. Instead, the focus should be on running "functionally equivalent" programs on the native mainframe operating systems, and again Linuxis often the best choice for this. Switching from Windows to Linux may not be "Redmond-sanctioned", but it getsthe job done.
Instead of SQL Server, consider something functionally equivalent like IBM's DB2 Universal Database, or perhaps an open source database like MySQL, PostgreSQL or Apache Derby. Well-written applications use standard SQL calls, so ifthe application does not try to use unique, proprietary features of MS SQL Server, you are in good shape.
In my discussion last November on [Microsoft Exchange email server], I mentioned that Bynari makes a functionally equivalent email server on Linux that works with your existing Microsoft Outlook clients. Your end-users wouldn't know you migrated to a mainframe! (well, they might notice their email runs faster)
So if your data center has three or more racks of Sun, Dell or HP "pizza box" or "blade" x86 servers, chances are you can migrate the processing over to a shiny new IBM z10 EC mainframe, save some money in the process, without too much impact to your existing Ethernet, SAN or storage system infrastructure. IBM can even help you dispose of the oldx86 machines so that their toxic chemicals don't end up in any landfill.

I got the following comment on my earlier post [A Recap of Storage Industry Acquisitions
], Reuben wrote:
According to Gartner data (from 2005!), host-based storage accounts for 34 percent of the overall market for external storage, with the remaining 66 percent going to "fabric-attached" (network) storage, expect this share to grow from 66 percent to 77 percent by 2007.What is the current reality? SAN vs. NAS, FC vs iSCSI?
IBM subscribes to a lot of data from different analysts, they all have their methods for collecting this data, from taking surveys of customers to reviewing financial results of each vendor. While theymight not agree entirely, there are some common threads that lead one to believe they represent "reality". Hereare some numbers from an IDC December 2007 report:
|Worldwide Disk Storage||2007 Petabytes||Percentage||2006-2011 CAGR|
While the 32/68 split is similar to the 34/66 split you mentioned before, you can see that external growth isgrowing faster, so internal host-based storage will drop to 25 percent by 2011, with external storage growing to 75 percent, very close to the 77 predicted. Looking at just the externaldisk storage, there are basically three kinds: DAS (direct cable attachment), NAS (file level protocols suchas NFS, CIFS, HTTP and FTP), and SAN (block-level protocols like FC, iSCSI, ESCON and FICON):
|Worldwide External Disk Storage||2007 Petabytes||Percentage||2006-2011 CAGR|
At these rates, fabric-attached (SAN and NAS) will continue to dominate the storage landscape.Looking more closely now at the block-oriented protocols.
|Worldwide External Disk Storage||2007 Petabytes||Percentage||2006-2011 CAGR|
|Fibre Channel (FC)||1733||83||48|
At these rates, iSCSI will overtake FC by 2011. IBM System Storage N series, DS3300 and XIV Nextraall support iSCSI attachment.
Jon Toigo over at DrunkenData offers some additional data from ex-STKer:[Fred Moore Outlook on Storage 2008]. I met Fredat a conference. He had left STK back in 1998, and started his own company called Horison. NeitherJon nor Fred cite the sources of his statistics, but the following comment leads me to assume hehasn't been paying attention closely to the tape market:
With the demise of STK, who will be the leader in the tape industry?
Depending on how old you are, you might remember exactly where you were when a significant eventoccurred, for example the[Space Shuttle Challenger
]explosion. For many IBMers, it was the day our friends at Sun Microsystems announced they were [puttingour lead tape competitor out of its misery
]. I was in New York that day, but there was still someconfetti on the floor in the halls of the IBM Tucson lab when I got home a few days later. IBM hasbeen the number one market share leader in tape for over the past four years.

This week I am in Japan, so my week's theme will center around travel, speaking at conferences, and Japan itself. I first travelled to Japan in the late 1980s, to visit a college friend who was working for Ford Motor Company, on assignment in Japan as liasion to Mazda Corp.
Back then, the only Japanese phrase I knew was "Wakarimashta" which means "I know" or "I understand". If you only know one phrase in a foreign language, this possibly could be the worst to know.
My second trip, I was better prepared. I learned three "survival phrases":
sumimasen - "I'm sorry/excuse me"
hanashimasen - "I don't speak"
wakarimasen - "I don't know / I don't understand"
These are great phrases to know individually, but even more powerful strung all together, to emphasize that you will begin speaking English, but at least with good reason (and perhaps a bit of irony.)
I've been to Japan many times since, and have picked up more of the language. When travelling to Japan, or anywhere for that matter, it is important to "pack light". I'll be gone for two weeks, but all I bring is a laptop bag and one carry-on piece of luggage.
I went on a trip to Prague (Czech Republic) with a female co-worker who brought FOUR pieces of luggage. One was just for shoes. Another piece was just for hair styling gel, make-up, face creams and finger nail polish. Today, the rules are different, and the TSA allows only a single quart-size plastic bag containing little jars of 3 ounces or less of liquids or gels. I didn't have any "quart-size" bags, so I used a smaller sandwich-size bag.
What does all this have to do with storage? I've helped many clients move data centers, and this involves moving their servers, their networks, and their storage. Servers and Networks are easy to move, but storage presents some challenges. In many cases, the entire company is shut down, the storage is moved, and then the company is operational again. Needless to say, it is best to do this over a weekend.
I tell clients to "pack light" and figure out what data they really need in the move. What do you really need to operate your business? Bring just that, the rest can arrive later.
This same concept applies for Business Continuity and Disaster Recovery planning. What do you really need after a disaster occurs? Can you run your business for a few weeks on that data, until the rest of the data is restored? If you can't run your entire business on that data, can you run your most important parts of your business?
If you run a bank, perhaps keeping your ATM cash machines running is more important than making out new loans. In Japan, if a bank has any outages that impact their ATM machines, they put out a full page advertisement in the local papers to apologize for the inconvenience.
Business Continuity is one of the nine "Infrastructure Solutions" that IBM can help clients with. If you are interested in learning more on how IBM can help you with your Business Continuity, click here.

Here we are again at Top Gun class.In between class topics, we often show short video clips.
This week, we saw IBM Executive Bob Hoey's wisdom on selling mainframe computers. Bob is the VP of Sales for our System z server line, but the lessons might also apply to high-end disk or enterprise tape libraries.

A [recent survey
] conductedby Fleishman-Hillard Researchindicates that the majority of disk-only customers are now lookingat adding tape back into their infrastructure. Here are some excerpts:
"Over two thirds of surveyed businesses said they were lookingto add tape storage back into their overall network infrastructure and of those respondents, over80-percent plan to add tape storage solutions within the next 12 months.The survey, which was taken in the fourth quarter of 2007, focused on the views of morethan 200 network administrators and mid-level tech specialists at mid-size to large companiesthroughout the United States.
The integration of tape storage into a tiered information infrastructure is highly strategic forcustomers, due to its low cost of ownership, low energy consumption and portability for dataprotection, said Cindy Grossman, Vice President of Tape Storage Systems, IBM. LTO tapetechnology is a perfect choice for enterprise and mid-sized customer with its proven reliability, highcapacity, high performance and ability to address data security with built-in encryption and dataretention requirements for the evolving data center.
According to the survey, 58-percent of the respondents use a combination of disk and tapefor long term archiving, 24-percent use tape exclusively, and 18-percent employ a disk-onlyapproach. In this group, 68-percent of the current disk-only users plan to start using tape for longtermarchiving, and over half (58-percent) plan to add tape for short-term data protection.The survey findings suggest that disk-only users may be experiencing a bit of buyer sremorse, said David Geddes, senior vice president at Fleishman-Hillard Research, who oversawthe study. We found that a wide majority of companies that employ purely disk-basedapproaches are looking to quickly include tape in their backup and archiving strategies."
While disk provides online data access and availability, tape provides additional data protectionand security, lower total cost of ownership (TCO), lower energy consumption (Tape is more "green"),and can be an important part of a long term data retention and compliance strategy.
Disk is more costly, more energy hungry, and some data, although it must be retained, may seldom, if ever be looked at, so why keep it spinning?
Speaking of TCO, in a recent 5-year TCO analysis by the Clipper Group titled[“Disk and Tape Square Off Again”]stored 2.4PB of data long term on SATA disk and on an LTO tape library, the disk system was:23:1 more costly, used 290 times the amount of energy than tapeEven with a data dedupe system like IBM System Storage N series, disk was still 5 times more costly than the tape system.
The Linear Tape Open (LTO) consortium --consisting of IBM, Hewlett-Packard (HP) and Quantum-- just released its "LTO-5" plans. With 2:1 compression,you will be able to pack up to 3TB of data on a single tape cartridge. And while dollar-per-GB declinefor disk is slowing down to 25-30 percent per year, tape continues to decline at a healthy 40 percent rate, so the price gap between diskand tape will actually widen even further over the next few years.
That's something to get excited about!

Continuing this week's theme about the products that were part of last week's IBM Information Infrastructurelaunch, I will cover today the IBM System Storage TS7650G ProtecTIER deduplication gateway.
This product is based on the technology from the[IBM acquisition of Diligent], featuring in-line deduplication processing. To learn more about deduplication, see mypost: [Eleven Answers about Deduplication from IBM].
So what did IBM change?
- Before acquisition, Diligent offered only software. The task of putting this software on an appropriate x86 server with sufficientmemory and processor capability was left as an exercise for the storage admin. With the TS7650G, IBM installs theProtectTIER software on the fastest servers in the industry, the IBM System x3850 M2 and x3950 M2. This eliminateshaving the storage admins pretend that they have hardware engineering degrees.
- Before acquisition, the software worked only on a single system. IBM was able to offer multiple configurations of the TS7650G, including a single-controller model as well as a clustered dual-controller model. The clustered dual-controller model can ingest data at an impressive 900 MB/sec, which is up to nine times faster than some of thecompetitive deduplication offerings.
- Before acquisition, ProtecTIER emulated DLT tape technology. This limited its viability, as the market sharefor DLT has dropped dramatically, and continues to dwindle. Most of the major backup software support DLT as anoption, but going forward this may not be true much longer for new tape applications.IBM was able to extend support by adding LTO emulation on theTS7650G gateway, future-proofing this into the 21st Century.
At last week's launch, covering so many products with so few slides, this announcement was shrunken down to a single line "Store 25 TB of backups onto 1 TB of disk, in 8 hours" and perhaps a few people missed that this wasactually covering two key features.
- With deduplication, the TS7650G might get up to 25 times reduction on disk. If you back up a 1 TB data basethat changes only slightly from one day to the next, once a day for 25 days, it might only take 1 TB, or so, of disk tohold all the unique versions, as most of the blocks would be identical, rather than 25 TB on traditional disk or tapestorage systems. The TS7650G can manage up to 1 PB of disk,which could represent in theory up to 25 PB of backup data.
- With an ingest rate of 900 MB/sec, the TS7650G could ingest 25 TB of backups during a typical 8 hour backup window.
The 25 TB of the first may not necessarily be the 25 TB of the second, but the wording was convenient for marketingpurposes, and a comma was used to ensure no misunderstandings.Of course, depending on the type of application, the frequency of daily change, and the backup software employed, your mileage may vary.

In case you haven't noticed, IBM System Storage makes most of their announcements on Tuesdays. IBM announced a lot today, so here is a quick run-down.
- Cisco storage networking products
IBM continues to resell Cisco switches and directors, but now can offer these with a 1-year IBM warranty.
The entry-level Cisco 9124offers 8 to 24 ports. For IBM BladeCenter, IBM now offers the Cisco10-port and 20-port modules that slide into the back of the chassis, and are functionally equivalent to the 9124.The original BladeCenter came with a 16-port module with 14 internal, but only 2 external, which severely hamperedbandwidth connectivity to external storage. These new modules provide more external ports to relieve that constraint.
The midrange Cisco9200switches have two models, both with 16 fixed ports, with the option for a blade that can provide 12, 24 or 48 additional ports. The 9216A has 16 FCP ports, and the 9216i has 14 FCP ports, and 2 GbE ports to act as a router, such as toconnect to a remote location for business continuity using Metro Mirror or Global Mirror.
The enterprise-class Cisco 9500directors can support up to 528 ports.
- TS3400 Tape Library
The new TS3400library is a small entry-level size library, supporting the enterprise-class TS1120 drive, providing interoperabilitywith the larger tape libraries, with all the support for tape encryption.
In addition to Linux, Unix, and WIndows, the TS1120 can now be connected to System i servers. In the past, the only IBMtape available to System i were the LTO models. There are a lot of businesses that need to comply with government regulations that are looking for tape encryption, and now IBM has made it accessible to more clients.
- 300GB drives at 15K RPM
The DS8000 can now support new drives with 300GB capacity at 15,000 RPM (15K). These can be up to 30 percent faster than the 10,000 RPM drives for typical workloads.
IBM continues its market leadership with these new set of features and offerings!

If regulatory compliance and protecting your data against security breaches is top of mind for you, I invite you to attend a webinar on a new enterprise encryption solution from IBM featuring the IBM System Storage™ TS1120 tape drive. On September 20, 2006 Jon Oltsik, Senior Analyst for Information Security with the Enterprise Strategy Group, will moderate a discussion on IBM’s encryption strategy and latest data security advances with a panel of our product and industry experts.
Securing your data – IBM Tape Encryption Solutions
I personally know Dianne McAdam, from the Clipper Group, so the following should be very interesting:
Tape vs. Disk Which Really Eats More Power[Read More]
Rich Bourdeau has written a nice article on InfoStor titled [Software as a Service (SaaS) meets Storage
]. Last year, IBM acquired Arsenal Digital, and he mentions both in this article.It is interesting how this has evolved over the years.
- Rent warehouse space for tapes
I remember when various companies offered remote storage for tapes. These would be temperature and humidity-controlledrooms, with access lists on who could bring tapes in, who could take tapes out, and so on. In the event of thedisaster, someone would collect the appropriate tapes and take them to a recovery site location.
- Rent online/nearline storage from a Storage Service Provider (SSP)
SSPs rented storage space on disk, or provided automated tape libraries that could be written to. With tapes being ejected and stored in temperature/humidity-controlled vaults. Electronic vaulting eliminates a lot of theissues with cartridge handling and transportation, is more secure, and faster. Rented disk space, based on a Gigabytes-per-month rate, could be used for whatever the customer wanted. If these were for backups or archive,then the customer has to have their own software, to do their own processing at their own location, sending the data to the remote storage as appropriate, and manage their own administration.
- Backup-as-a-Service and Archive-as-a-Service
We are now seeing the SaaS model applied to mundane and routine storage management tasks. New providers can offerthe software to send backups, the disk to write them to, and as needed the tape libraries and cartridges to rollover when the disk space is full. Disk capacity can be sized so that the most recent backups are on immediately accessible for fast recovery.
The same concept can be applied to archives. The key difference between a backup and an archive is that backups areversion-based. You might keep three versions of a backup, the most recent, and two older copies, in case something is wrong with the most recent copy, you can go back to older copies. This could be from undetected corruption of the data itself, or problems with the disk or tape media. An archive, on the other hand, is time-based. You want this data to be kept for a specific period of time, based on an event or fixed period of years.
Since BaaS and AaaS providers know what the data is, have some idea of the policies and usage patterns will be, can then optimize a storage solution that best meets service level agreements.
This has certainly come a long way!

I survived my first day at SNW Spring 2007
.This is my first time at SNW, but it is very much like many of the other conferences I have been to.It officially started Monday morning with pre-conferencetutorials and primer break-outsessions that covered storage fundamentals, but I didn't arrive until late Monday night due to highwind conditions at the Phoenix airport that delayed my travel.
Tuesday started out with main tent sessions. Ron Milton, VP of ComputerWorld that puts on this conference,and Vincent Franceschini, Chairman of the Board for SNIA, kicked off the event.It didn't take them long to get into the alphabet soup: ILM, ITIL, SMI-S, XAM, IMA, MMA, DDF,MF, DMF, IPSF, SSIF, and SRM.Several hundred people had "voting devices" so that they could participate in "informal" surveys.
Q1. What was the greatest need?
- 37% Storage Resource Management (SRM) tools
- 19% Storage Virtualization
- 19% Information Lifecycle Management (ILM)
- 14% Integration with other management tools
- 11% Compliance storage for regulations
Q2. What are people doing to address storage infrastructure complexity?
- 33% Deploying new SRM and SAN management tools
- 26% Adopting "Storage as a Service" methodology
- 22% Deploying new storage virtualization technologies
- 8% Hiring more staff
- 9% (complexity was not an issue)
The first keynote speaker was Cora Carmody, CIO of SAIC. In the late 1980s and early 1990s, I did a lot of work with SAIC here in San Diego, and so IBM sent me to San Diego quite frequentlyfor face-to-face meetings with them. Her talk was cryptically titled "Jumbo Shrimp, InformationManagement, and the Mark of the Beast." Coming up with good titles is important. Some of herkey points:
- "Information management" was as much an oxymoron as "jumbo shrimp" or "military intelligence".(SAIC is a general contractor for the US Military, so this was especially funny).
- Computer data needs both "ownership" and "stewardship".
- Gartner analyst reports that 50% of digital information for a business resides in personal files onindividual PCs.
- PAN-StaRRs project is ingesting 10TB per week of astronomical data.
- TeraTEXT(R) project is a non-relational database that supports a large mix of structured and unstructured content.
- The next "Y2K" crisis for the USA is changing from 3-digit to 4-digit area codes for our telephone numbers.
- Battery size and life have not advanced as fast as we need
- There has been little progress in "User Interface" ease of use
- Formats and standards are picked for the most part by the winning vendors, and it is the silence of themarketplace that lets them get away with this.
- We are overly reliant on an inherently insecure medium.
- The "mark of the beast" refers to exciting new technologies based on "presence awareness". For example,some hotels now are able to check you into the hotel as you drive up in your car, based on your car's licenseplate. Some 24-hour gyms use your fingerprint as your entry credentials, eliminating the need to staff peopleat the front desk.
IBM's own Barry Rudolph, presented "Storage in an Age of Inconvenient Truths", dressed up like Oscar-winner andformer USA Vice President Al Gore. Barry's focus was on the growingconcern of over environmental Power and Cooling issues in the data center. According to IDC, the cost of power and cooling an individual server, over its lifetime, now exceeds its acquisition cost. Storage devices are not as bad as servers in this regard. Data centers now consume 1.2% of the worlds energy.
Over lunch, I heard Tony Asaro from ESG present "The Need for Highly Virtualized Storage Systems withina Virtualized Data Center." His concern is that there is still a "heavy touch" required to manage storage.Without virtualization, your data center is less than the sum of its parts. Although IBM has been doingstorage virtualization since 1974, Tony mentioned that most storage vendors were "late to the party".He argues that "internal virtualization" inside storage arrays is not enough, you need "external virtualization"(like the IBM System Storage SAN Volume Controller) to virtualize your entire infrastructure.What storage administrators would like is for storage to have consumer levels of "ease of use", and today'snon-virtualized storage environments are nowhere near that.
"The great advantage [the telephone] possesses over every other form of electrical apparatus consists in the fact that it requires no skill to operate the instrument."
- Alexander Graham Bell, 1878
I attended a few break-out sessions in the afternoon.
- Ralph Wescott, Pacific Northwest National Library
Ralph presented "Crisis of Capacity" which covered the drastic actions he had to take to handle power and coolingin their expanding data center during their summer months, where temperatures peak up to 105 degrees. This included creating "hot" and "cold" aisles onhis raised floor by re-organizing the perforated floor tiles, and doing a better job standardizing how cables areconnected to the back of racks and up through the ceiling to maximize airflow. An amp-meter on each power strip was used to measure the powerused at each rack, which allowed them to better prioritize their efforts. Their Air Conditioning unit was only 12inches from the concrete floor, and raising it to 18 inches greatly reduced noise and vibration. Adding a second AC unit made a world of difference. Finally, they eliminatedKVMs, because people who use KVMs break other parts of thedata center. His rule of thumb: the cooling requirements will be 50% of the rated power requirements for equipment.
- Terry Yoshi, Intel internal IT department, as a member of the SNIA's end user council
Terry presented "Taming the SAN Complexity". The problem with "complexity" as a concept is that it is very subjective, difficult to quantify, and therefore difficult to manage. He presented complexity in four areas:Organizational structure of the company as a whole; skill sets required of the IT staff; business process andprocedures; and technology. Dealing with complexity is a battle between Old School (because we've always doneit this way) and New School (because it is new and different technology). Storage Area Networks are inherentlya "shared resource", and the increased complexity is a direct result of the low reliability of the componentsand devices it is composed of. People should focus on the "Total Cost of Ownership" (TCO) for a SAN, and not just the initial acquisitionprice of SAN gear.He was not a fan of the "dual/multiple" vendor strategy that many companies employto reduce costs. His suggestion that things should be tried out first on your "test SAN" caused some chuckles,as few have such a thing. Finally, he suggested not only documenting "Best Practices" and "Best Known Methods"but also things that have been found not to work, his do-not-try-this-at-home list.
- Tony Antony, Cisco marketing manager for Optical products
This was an overview of the technologies available for long distance connections for disaster recovery,business continuity, and resilience. He covered three levels.
His rule of thumb: one buffer credit for every kilometer at 2Gbps speed (for every 2km at 1Gbps).
- IP - Fibre Channel of IP (FCIP) offers the greatest "global" distance but forces people into asynchronous mirroring.
- SONET/SDH - SONET is what we call it in the USA, and SDH is what it is called in other countries. This provides state-to-state or "out-of-region" distances, which is ideal to meet certain government regulations for homeland defense. He suggests this is offered when dark fiber or DWDM is not available.
- DWDM/CWDM - this is using a prism to run multiple colors of light through a single fiber optic cable. CWDM ischeaper, but only handles 8 signals per cable. DWDM can handle 32 to 160 signals per cable, but is more expensive.
The day ended at the "Expo". I hung out at the IBM booth to help answer questions and network with others.

Well, I have left Japan, and while everyone else is enjoying the Super Bowl, I am now in Australia, at another conference.Today I had the pleasure to hear filmmakers talk about their successes, and how IBM helps the movie industry.
- Khoa Do
At one extreme was Khoa Do, independent filmmaker. After acting in movies asideMichael Caine and Billy Zane, he decided to become his own director. He started a project to help seven disadvantaged youths from a poor drug-ridden section of Sydney, by having them act in his first full-length film.Armed with only an IBM laptop and small budget, he made the film called "The Finished People" that had critical acclaim.
The film was a success, and many of the disadvantaged youths have gone on to act in other movies. In 2005, Khoa Do was named "Young Australian of the Year".
Thanks to IBM technology, filmmaking is now accessible to a wider number of aspiring wanna-be directors. It is no longer necessary to be part of a large film studio with a multi-million dollar budget to tell your story.
- Xavier Desdoigts
At the other extreme, was Xavier Desdoigts, director of technical operations at Animal Logic, the Computer Graphics (CG) arthouse that produced special effects of movies like "The Matrix", "House of Flying Dragons" and "World Trade Center". They started with producing digital effects for TV commercials, like this one forCarlton Draught Beer.
With the support of a large film studio and multi-million dollar budget, Animal Logic now boasts the 86th most powerful "Supercomputer" based on IBM BladeCenter technology, with over 4000 servers connected into a cluster, for making the movie "Happy Feet". The movie took four years to make, with over 500 people, of 27 different nationalities. It was the first CG movie made in Australia, and has been well-received by audiences worldwide.
Mr. Desdoigts gave out some interesting facts and figures about the movie:
- While visually stunning on the big screen, each frame is only 1.4 Megapixel, about the same resolution as most camera phones.
- In one scene, there are 427,086 penguins all appearing on frame.
- Mumble, the lovable lead character, is made up of over 6 million feathers.
- As many as 17 dancers were "motion-captured" to choreograph the tap-dancing and character interaction segments.
- Only one system admin was needed to manage this entire server farm. (IBM Systems Director technology makes this possible)
- The movie consumed 103 TB of disk space, backed up to 595 LTO tape cartridges.
- An estimated 17 million CPU-hours were needed for all the processing and rendering.
Rather than talking about technology for technology sake, these filmmakers showed how technology couldbe put to use, in a practical sense, to provide the world something of value.

Last week, I opined that Monday's IDC announcement "IBM #1 in combined disk and tape storage hardwaresales for 2006" was in part because of a resurgence of interest in tape
, with four specific examples. There was a lot of reaction and reflection fromboth sides.
- On the one side...
EMC blogger Mark Twomey at Storagezilla admits that perhapsTape Isn't Dead after all,is perhaps the best place to put long-term archive data, but not for backup? EMC's "creative marketing types" put out this Fun With Tape video that I found amusing. (It asks for a first name,last name, and e-mail address, which are then embedded into the resulting video itself, and perhaps forwarded to your nearest EMC sales rep, so answer according to your wishes for privacy).
The "mummy wrapped in tape media" seems to be a common theme, and shows up again in LiveVault'svideo with John Cleese, which makes the same argument asthe EMC video above, namely: switch your backups from tape to disk because we are a disk-only vendor.
- ... and on the other side
JWT over at DrunkenData asks Which is greener, disk or tape?Tape is, of course, by a long shot, and an essential part of IBM's Big Green initiative, a project to invest$1US Billion dollars per year for data centers to be more efficient for power and cooling.
Sun/StorageTek blogger Randy Chalfant questions the Death of Tape, and argues thatdisk-only solutions suffer from atrophy.The results he posts from a survey of 200 customers are similar to those we've seen with customers using IBM TotalStorage Productivity Center, our software to help evaluate data usage, and identify misuse, in your data center.
To my readers in the USA, United Kingdom, Ireland, South Africa, China and Japan, and a few other countries, Happy Father's Day!

On the news today, they mentioned it was "Happy Pi Day"
. Today is the 14th day of the 3rd month, and "pi" is about 3.14159, the ratio of the circumference of a circle to its diameter. So, in Tucson it is celebrated on 3/14, at 1:59pm MST.
The ratio has a lot to do with storage.
Tape wrapped around a hub. Tape is thin, but not completely, so wrapping hundreds of meters on tape results in a change in diameter of the spool. This impacts the rotational velocity needed to get the linear meters-per-second on the tape media consistent as the diameter changes when you wind down from a full spindle toward the hub. IBM has variable speed motors and other clever technologies to handle this adjustment.
Disks spin at consistent speeds, but tracks on the outside edge travel faster across the head than the inside tracks.Currently, the top speeds for disk are 15000 Revolutions per minute (RPM). As faster rotational speeds are investigated, the researchers find they need to make the diameters smaller to compensate.
The diameters of disks were based on "U", the unit height of standard 19" racks. A "U" is 1.75 inches, and standard floppy diskettes were 5.25 inch (3U) and 3.5 inch (2U). For those who have a difficult time remember how many inches a "U" is, it is the height of a standard two-by-four (2x4) piece of lumber.
The value of "pi" has been calculated to over a billion significant digits. Here is a cuteapplet to use if you ever need the value to any level of accuracy.

It's official! IBM System Storage TS1120 tape drive takes home the gold award, the product of the year, announced by Storage magazine.
I spent 18 hours traveling from Australia to China yesterday, and we were partially delayed due to weather, but felt that it was necessary to discuss the innovative use of encryption on this drive.
While most consider the TS1120 an "Enterprise-class" tape technology for the mainframe, it is also attachable to the smallest distributed systems running Windows, Linux, or various flavors of UNIX. Rather than limit users with an Encryption Key Manager that only ran on z/OS, IBM instead chose to implement it in Java, that can be run on anything from z/OS to Linux, Unix and Windows platforms, giving clients choice and flexibility in their deployment.
The design is quite clever and elegant. In the encryption world, there are two ways to encrypt.
- Symmetric Key
This is very fast, because it uses a single key for both encryption and decryption, and can be incorporated on a chip. The problem is that anyone with the key can read the sensitive data.
- Asymmetric Key
This is slower, but more secure, using two separate keys. The public "encryption" key takes clear data and encrypts it. Anyone can be freely given this key, as they cannot use it to decrypt any other data. The private "decryption" key is able to decrypt the data, so that one is kept secret. If two business plan to exchange lots of tapes, they can exchange their "encryption" keys to each other.
So, let's say that Green, Inc. wants to send a tape to Blue, Co. Blue has already provided its public "encryption" key to Green, so Green does the following:
- Generate a unique data key, will call it the "red key", and there is one for each tape. It is a standard AES 256-bit symmetric key that can be processed with less than one percent overhead on the tape drive. All the data is encrypted with this key.
- Store the red key on the tape. How does Green give Blue the red key? Green encrypts it with Blue's RSA 2048-bit public "encryption" key. This is stored on three places on the tape cartridge, one in memory, and the other two on the media itself.
- Sends the tape over to Blue Co.
When it arrives on the dock at Blue Co., they do the following:
- Mount the tape and decrypt the "red key" using Blue's super-secret private decryption key.
- Pass the "red key" to the tape drive, and have it read, append or re-write the tape.
If the super-secret private key is ever compromised, all you have to do is mount the tape, unlock the red key with the old private key, and re-lock the red key with a new public key. Since the red key doesn't change, the rest of the data can be left in tact. The whole process takes less than 5 minutes, compared to Sun Microsystems method, which could take 1-2 hours per cartridge, having to decrypt and re-encrypt the entire data stream.
