Well, I'm back safely from my tour of Asia. I am glad to report that Tokyo, Beijing and Kuala Lumpur are pretty much how I remember them from the last time I was there in each city. I have since been fighting jet lag by watching the last thirteen episodes of LOST season 6 and the series finale.
Recently, I have started seeing a lot of buzz on the term "Storage Federation". The concept is not new, but rather based on the work in database federation, first introduced in 1985 by [A federated architecture for information management] by Heimbigner and McLeod. For those not familiar with database federation, you can take several independent autonomous databases, and treat them as one big federated system. For example, this would allow you to issue a single query and get results across all the databases in the federated system. The advantage is that it is often easier to federate several disparate heterogeneous databases than to merge them into a single database. [IBM Infosphere Federation Server] is a market leader in this space, with the capability to federate DB2, Oracle and SQL Server databases.
Storage expansion: You want to increase the storage capacity of an existing storage system that cannot accommodate the total amount of capacity desired. Storage Federation allows you to add additional storage capacity by adding a whole new system.
Storage migration: You want to migrate from an aging storage system to a new one. Storage Federation allows the joining of the two systems and the evacuation from storage resources on the first onto the second and then the first system is removed.
Safe system upgrades: System upgrades can be problematic for a number of reasons. Storage Federation allows a system to be removed from the federation and be re-inserted again after the successful completion of the upgrade.
Load balancing: Similar to storage expansion, but on the performance axis, you might want to add additional storage systems to a Storage Federation in order to spread the workload across multiple systems.
Storage tiering: In a similar light, storage systems in a Storage Federation could have different capacity/performance ratios that you could use for tiering data. This is similar to the idea of dynamically re-striping data across the disk drives within a single storage system, such as with 3PAR's Dynamic Optimization software, but extends the concept to cross storage system boundaries.
To some extent, IBM SAN Volume Controller (SVC), XIV, Scale-Out NAS (SONAS), and Information Archive (IA) offer most, if not all, of these capabilities. EMC claims its VPLEX will be able to offer storage federation, but only with other VPLEX clusters, which brings up a good question. What about heterogenous storage federation? Before anyone accuses me of throwing stones at glass houses, let's take a look at each IBM solution:
IBM SAN Volume Controller
The IBM SAN Volume Controller has been doing storage federation since 2003. Not only can IBM SAN Volume Controller bring together storage from a variety of heterogenous storage, the SVC cluster itself can be a mix of different hardware models. You can have a 2145-8A4 node pair, 2145-8G4 node pair, and the new 2145-CF8 node pair, all combined together into a single SVC cluster. Upgrading SVC hardware nodes in an SVC cluster is always non-disruptive.
IBM XIV storage system
The IBM XIV has two kinds of independent modules. Data modules have processor, cache and 12 disks. Interface modules are data modules with additional processor, FC and Ethernet (iSCSI) adapters. Because these two modules play different roles in an XIV "colony", that number of each type is predetermined. Entry-level six-module systems have 2 interface and 4 data modules. Full 15-module systems have 6 interface and 9 data modules. Individual modules can be added or removed non-disruptively in an XIV.
IBM Scale-Out NAS
The SONAS is comprised of three kinds of nodes that work together in concert. A management node, one or more interface nodes, and two or more storage nodes. The storage nodes are paired to manage up to 240 nodes in a storage pod. Individual interface or data nodes can be added or removed non-disruptively in the SONAS. The underlying technology, the General Parallel File System, has been doing storage federation since 1996 for some of the largest top 500 supercomputers in the world.
IBM Information Archive (IA)
For the IA, there are 1, 2 or 3 nodes, which manages a set of collections. A collection can either be file-based using industry-standard NAS protocols, or object-based using the popular System Storage™ Archive Manager (SSAM) interface. Normally, you have as many collections as you have nodes, but nodes are powerful enough to manage two collections to provide N-1 availability. This allows a node to be removed, and a new node added into the IA "colony", in a non-disruptive manner.
Even in an ant colony, there are only a few types of ants, with typically one queen, several males, and lots of workers. But all the ants are red. You don't see colonies that mix between different species of ants. For databases, federation was a way to avoid the much harder task of merging databases from different platforms. For storage, I am surprised people have latched on to the term "federation", given our mixed results in the other "federations" we have formed, which I have conveniently (IMHO) ranked from least effective to most effective:
The Union of Soviet Socialist Republics (USSR)
My father used to say, "If the Soviet Union were in charge of the Sahara desert, they would run out of sand in 50 years." The [Soviet Union] actually lasted 68 years, from 1922 to 1991.
The United Nations (UN)
After the previous League of Nations failed, the UN was formed in 1945 to facilitate cooperation in international law, international security, economic development, social progress, human rights, and the achieving of world peace by stopping wars between countries, and to provide a platform for dialogue.
The European Union (EU)
With the collapse of the Greek economy, and the [rapid growth of debt] in the UK, Spain and France, there are concerns that the EU might not last past 2020.
The United States of America (USA)
My own country is a federation of states, each with its own government. California's financial crisis was compared to the one in Greece. My own state of Arizona is under boycott from other states because of its recent [immigration law]. However, I think the US has managed better than the EU because it has evolved over the past 200 years.
The Organization of the Petroleum Exporting Countries [OPEC]
Technically, OPEC is not a federation of cooperating countries, but rather a cartel of competing countries that have agreed on total industry output of oil to increase individual members' profits. Note that it was a non-OPEC company, BP, that could not "control their output" in what has now become the worst oil spill in US history. OPEC was formed in 1960, and is expected to collapse sometime around 2030 when the world's oil reserves run out. Matt Savinar has a nice article on [Life After the Oil Crash].
United Federation of Planets
The [Federation] fictitiously described in the Star Trek series appears to work well, an optimistic view of what federations could become if you let them evolve long enough.
Given the mixed results with "federation", I think I will avoid using the term for storage, and stick to the original term "scale-out architecture".

Well, it's Tuesday again, and that means IBM announcements! Right on the heels of our big storage launch on February 9, today IBM announced some exciting options for its modular disk systems. Let's take a look:
2TB SATA-II drives
That's right, you can now DOUBLE your capacity with 2TB SATA type-II drives on the DS3950, DS4200, DS4700, DS5020, DS5100 and DS5300 disk controllers, as well as the DS4000 EXP420, EXP520, EXP810, EXP5000 and EXP5060 expansion drawers. Here are the Announcement Letters for the [HVEC] and [AAS] ordering systems.
300GB Solid State Drives
IBM also announces 300GB solid state drives (SSD) for the DS5100 and DS5300. These are four times larger than the 73GB drives IBM offered last year, for those workloads that need high read IOPS such as Online Transaction Processing (OLTP) and Enterprise Resource Planning (ERP) applications. Here is the [Announcement Letter].
New N series model N3400
For customers that need less than the minimum 21TB that our IBM Scale-Out Network Attach Storage (SONAS) can provide, IBM offers the new N3400 unified storage disk system, with support for NFS, CIFS, iSCSI and FCP. This is a 2U high 12 drive model that can be expanded up to 136 drives, basically doubling all the stats from last year's N3300 model. Fellow blogger, Rich Swain (IBM), does a great job recapping the speeds and feeds over on his blog [News and Information about IBM N series].
It also appears that the reports and rumors of the death of the DS6800 are premature. Don't believe misleading statements from competitors, such as those found written by fellow blogger BarryB (EMC), aka "the Storage Anarchist", in his latest post [Bring Out Your Dead] showing a cute little tombstone with "Feb 2010" on the bottom. Actually, if he had bothered to read IBM's [Announcement Letter], he would have realized that IBM plans to continue to sell these until June. Of course, IBM will continue to support both new and existing DS6800 customers for many years to come.
Technically, BarryB does not make any factually incorrect statements for me to correct on his blog. The idea that a product is "dead" is, of course, just opinion, and competitors poke fun at each others' announcements every day. One could argue that the EMC V-Max was "dead" after the ITG whitepaper [Cost/Benefit Case for IBM XIV Storage System - Comparing Costs for IBM XIV and EMC V-Max Systems] demonstrated that the IBM XIV cost 63 percent less than a comparable EMC V-Max over the life of three years total cost of ownership (TCO) back in July 2009. The comparison was made with data from clients in a variety of industries including manufacturing, health care, life sciences, telecommunications, financial services, and the public sector. This could explain why so many EMC customers are buying or investigating the IBM XIV and the rest of the IBM storage portfolio.
In addition to dominating the gaming world, producing chips for the Nintendo Wii, Sony PlayStation, and Microsoft Xbox 360, IBM also dominates the world of Linux and UNIX servers. Today, IBM announced its new POWER7 processor, and a line of servers that use this technology. Here is a quick [3-minute video] about the POWER7.
While others might be [Dancing on Sun's grave], IBM instead is focused on providing value to the marketplace. Here is another quick [2-minute video] about why thousands of companies have switched from Sun, HP and Dell over to IBM.
Am I dreaming? On his Storagezilla blog, fellow blogger Mark Twomey (EMC) brags about EMC's standard benchmark results, in his post titled [Love Life. Love CIFS.]. Here is my take:
A Full 180 degree reversal
For the past several years, EMC bloggers have argued, both in comments on this blog, and on their own blogs, that standard benchmarks are useless and should not be used to influence purchase decisions. While we all agree that "your mileage may vary", I find standard benchmarks are useful as part of an overall approach in comparing and selecting which vendors to work with, and which architectures or solution approaches to adopt, and which products or services to deploy. I am glad to see that EMC has finally joined the rest of the planet on this. I find it funny this reversal sounds a lot like their reversal from "Tape is Dead" to "What? We never said tape was dead!"
Impressive CIFS Results
The Standard Performance Evaluation Corporation (SPEC) has developed a series of NFS benchmarks, the latest, [SPECsfs2008] added support for CIFS. So, on the CIFS side, EMC's benchmarks compare favorably against previous CIFS tests from other vendors.
On the NFS side, however, EMC is still behind Avere, BlueArc, Exanet, and IBM/NetApp. For example, EMC's combination of Celerra gateways in front of V-Max disk systems resulted in 110,621 OPS with overall response time of 2.32 milliseconds. By comparison, the IBM N series N7900 (tested by NetApp under their own brand, FAS6080) was able to do 120,011 OPS with 1.95 msec response time.
Even though Sun invented the NFS protocol in the early 1980s, they take an EMC-like approach against standard benchmarks to measure it. Last year, fellow blogger Bryan Cantrill (Sun) gives his [Eulogy for a Benchmark]. I was going to make points about this, but fellow blogger Mike Eisler (NetApp) [already took care of it]. We can all learn from this. Companies that don't believe in standard benchmarks can either reverse course (as EMC has done), or continue their downhill decline until they are acquired by someone else.
(My condolences to those at Sun getting laid off. Those of you who hire on with IBM can get re-united with your former StorageTek buddies! Back then, StorageTek people left Sun in droves, knowing that Sun didn't understand the mainframe tape marketplace that StorageTek focused on. Likewise, many question how well Oracle will understand Sun's hardware business in servers and storage.)
What's in a Protocol?
Both CIFS and NFS have been around for decades, and comparisons can sometimes sound like religious debates. Traditionally, CIFS was used to share files between Windows systems, and NFS for Linux and UNIX platforms. However, Windows can also handle NFS, while Linux and UNIX systems can use CIFS. If you are using a recent level of VMware, you can use either NFS or CIFS as an alternative to Fibre Channel SAN to store your external disk VMDK files.
The Bigger Picture
There is a significant shift going on from traditional database repositories to unstructured file content. Today, as much as [80 percent of data is unstructured]. Shipments this year are expected to grow 60 percent for file-based storage, and only 15 percent for block-based storage. With the focus on private and public clouds, NAS solutions will be the battleground for 2010.
So, I am glad to see EMC starting to cite standard benchmarks. Hopefully, SPC-1 and SPC-2 benchmarks are forthcoming?
I almost sprayed coffee all over my screen when I read this post from fellow blogger from EMC Mark Twomey on his StorageZilla blog titled [Dead End]. In it he implies that you should only consider storage technologies based on x86 technologies such as those from Intel, not other CPU technologies like POWER or MIPS.
When IBM first came out with the SAN Volume Controller in 2003, we were able to show that adding Intel-based SVC nodes can improve the performance and functionality of POWER-based DMX boxes from EMC. EMC salesmen often retorted with "Yes, but do you really want to risk your mission-critical data going through an Intel-based processor solution?" This FUD implied that Intel had a bad reputation for quality and reliability. The original Symmetrix were based on Motorolla 68000's but they modernized to use IBM's POWER chips in their later models. EMC's previous attempt to use Intel technology was their EMC Invista, a commercial failure. It is no surprise then that EMC DMX customers are scared to death to move their mission critical data over to Intel-based V-max.
I have found the primary reason people fear Intel-based solutions is their experience with poorly-written Windows programs. There were enough of these poorly-written Windows programs that everyone has either personal experience, or knows someone who has, and that was enough.
It reminds me of the time I was in Vac, Hungary, giving a lab tour to a set of prospective clients where we manufacture the DS8000 series and SAN Volume Controller. Rows and rows of beautiful Hungarian women sliding disk drives in place, and big hefty Hungarian beefcake moving the finished units to their appropriate places. The head of the facility explained all about the hardware technology, how we check and double check all of the equipment individually, and together as a system. One client stated "Yes, but how often are problems from the hardware? We find nearly all of our problems on disk systems from whichever storage vendor we buy from are in the microcode." It's true.
Both Intel-based processors and POWER-based processors have all the technological functions needed to run storage systems. The difference is all in the microcode. So, if you are looking for safe and stable microcode, the IBM System Storage DS8700 continues its POWER-based tradition for compatibility with previous models. For those that demand x86-based units, the IBM SAN Volume Controller has been around since 2003, the XIV Storage System has been in production since 2005, and our IBM N series are also Intel-based, running Version 7 of the ONTAP operating system.
This week, scientists at IBM Research and the California Institute of
Technology announced a scientific advancement that could be a major
breakthrough in enabling the semiconductor industry to pack more power
and speed into tiny computer chips, while making them more energy
efficient and less expensive to manufacture. IBM is a leader in
solid-state technology, and this scientific breakthrough shows promise.
But first, a discussion of how solid-state chips are made in the first place. Basically, a round thin wafer is etched using [photolithography]
with lots of tiny transistor circuits. The same chip is repeated over
and over on a single wafer, and once the wafer is complete, it is
chopped up into little individual squares. Wikipedia has a nice article
on [semiconductor device fabrication], but I found this
[YouTube video] more illuminating.
Up until now, the industry was able to get features down to 22
nanometers, and were hitting physical limitations to get down to
anything smaller. The new development from IBM and Caltech is to use
self-assembling DNA strands, folded into specific shapes using other
strands that act as staples, and then using these folded structures as
scaffolding to place in nanotubes. The result? Features as small as 6 nanometers. How cool is that?
While NAND Flash Solid-State Drives are available today, this new
technique can help develop newer, better technologies like Phase Change
Back in June, I mentioned this blog was [Moving to MyDeveloperWorks] which is based on IBM Lotus Connections.
Finally, the move is complete for all bloggers. If you are having problems with the redirects, you might need to unsubscribe and re-subscribe in your RSS feed reader. Here are the new links for several IBM bloggers that have moved over:
Well, it's Tuesday, and you know what that means? IBM announcements!
Today we had several for the IBM System Storage product line. Here are some of them:
DS8000 gets thinner, leaner and faster
The 4.3 level of microcode for the IBM System Storage DS8000 series disk systems [announced enhancements] for both fixed block architecture (FBA) LUNs and count key data (CKD) volumes.
For FBA LUNs that attach to Linux, UNIX and Windows distributed systems, IBM announced DS8000 Thin Provisioning native support. Of course, many people already had this by putting IBM System Storage SAN Volume Controller (SVC) in front, but now DS8000 clients out there without SVC can also achieve benefits ofthin provisioning. This support also improves quick initialization a whopping 2.6 times faster.
For CKD volumes attached to z/OS on System z mainframes, IBM announced zHPF multitrack support for z/OS 1.9 and above. zHPF provide high performance FICON performance, and can now handle multitrack I/O transfers foreven better performance for zFS, HFS, PDSE, and extended striped data sets.
XIV gets better connected
A lot of XIV[announced enhancements] and preview announcements centered around better connectivity. Here's a run down:
Better host attachment connectivity by beefing up the interface modules that hold the FCP and iSCSI interface cards. XIV disk arrays have 3 to 6 of these in different configurations, and since they manage both their own disks,as well as receive host I/O requests for other disks, are basically doing double-duty.These interface modules can now be ordered as [Dual-CPU] modules.
Better infrastructure management by connecting XIV with the industry standard SMI-S interface to IBM Tivoli Storage Productivity Center. Now, XIV can be part of the single pane of glass console that manages all of your other disk arrays, tape libraries and SAN fabrics.
Better copy services for backups by connecting XIV with IBM Tivoli Storage Manager Advanced Copy Services. TSM for Advanced Copy Services is application aware and can coordinate XIV Snapshots similar to its current support for SVC and DS8000 FlashCopy capabilities.
Better connectivity to security systems by supporting LDAP credentials. Before, you had individual userid and passwords for each XIV, and these were probably different than all the other userid/password combinations you have for every other box on your data center floor. IBM is working on getting all products to support theLightweight Directory Access Protocol, or [LDAP] so that we can reach the nirvana of "single sign-on",one userid/password per administrator for all IT devices in the company.
Better support with flexible warranty periods and non-disruptive code load options.
Better remote copy support by connecting to sites far, far away. IBM previewed that it will provideasynchronous disk mirroring from one XIV to another XIV natively. Before this, XIV's synchronous mirroring was limited to 300km distances. Many of our clients do long distance global mirroring of their XIV today behind an SVC, but again, for those out there that don't yet have an SVC, this can be a reasonable alternative.
TS7650 ProtecTIER data deduplication appliance now offers "no dedupe" option
In what some might consider a surprising move, IBM announced a "no dedupe" licensing option on their premiere deduplication solution, which somewhat reminds me of IBM's NOCOPY option on DS8000 FlashCopy. At first I thought "Are you kidding me?!?!" However, this new license option allows the TS7650 appliance to compete with other virtual tape libraries (VTL) that do not offer deduplication capability on an even playing field. It also allows TS7650 to be used for data that doesn'tdedupe very well, such as seismic recordings, satellite images, or what have you. There are also clients who do not yet feel comfortable to dedupe their financial records for compliance reasons.This option now allows IBM to withdraw from marketing the TS7530 non-dedupe library. Having one technology thatdoes both dedupe and no-dedupe is better than offering two separate libraries based on different technologies.
The ProtecTIER series also announced [IP remote distance replication]. This can be used to replicate virtualtape cartridges in one ProtecTIER over to another ProtecTIER at a remote location. You can decide to replicateall or just a subset of your virtual tapes, and this feature can be used to migrate, merge or split ProtecTIERconfigurations as your needs grow. Before this support, our TS7650G clients replicated the disk repositoryusing native disk array replication technology, such as Global Mirror on the DS8000, but that meant that all data was replicated over to the secondary site. Now, with this new IP replication feature, you can be selective, and replicate only those virtual tapes that are mission critical.
The appliance now supports up to 36TB of disk capacity, and the new "IBM i" operating system on System i servers,formerly known as i5/OS.
GPFS does Windows
IBM's General Parallel File System (GPFS) has the lion's marketshare of file systems used in the [Top 500 Supercomputers]. For a while, it was limited to just Linux and AIX operating system support, but version 3.3 [extends this to Windows 2008 on 64-bit architectures]. GPFS isthe file system used in IBM's Scale-Out File Services, the underlying technology of IBM's Cloud Computing and Storage offerings.
As I mentioned in my post [Moving Over to MyDeveloperWorks], those of us bloggers on IBM's DeveloperWorks are moving over to a new system called "MyDeveloperWorks" which has a host of new features.
Fortunately for me, I missed the note to volunteer to be one of the first bloggers on the block to volunteer to move over. I was traveling and decided not to deal with it until I got back.However, fellow IBM Master Inventor, Barry Whyte, was not so lucky. It is safe to say he was stupid enough to volunteer, and is probably regretting the decision every day since. In case you lost his RSS feed, or can't find him anymore on Google or whatever search engine, here is his[new blog].
As for my blog, I have asked to postpone the move until all the problems that Barry has encountered are resolved. That might be a awhile, but if you lose access to mine sometime in the near future, hopefully at least you have been warned as to what might have happened.
Continuing this week's theme of doing important things without leaving town, I present our results foran exciting project I started earlier this year.
For seven weeks, my coworker Mark Haye and I voluntarily led a class of students here in Tucson, Arizona in an after-school pilot project to teach the ["C" programming language] using [LEGO® Mindstorms® NXT robots]. The ten students, boys and girls ages 9 to 14 years old, were already part of the FIRST [For Inspiration and Recognition of Science and Technology] program, and participated in FIRST Lego League[FLL] robot competitions.Since the students were already familiar building robots, and programming them with a simple graphical system of connecting blocks that perform actions. However, to compete in the next level of robot competitions, FIRST Tech Challenge [FTC],we need to leave this simple graphical programming behind, and upgrade to more precise "C" programming.
Mark is a software engineer for IBM Tivoli Storage Manager and has participated in FLL competitions over the past nine years. This week, he celebrates his 25th anniversary at IBM, and I celebrate my 23rd. The teacher, Ms. Ackerman, and the students referred to us as "Coach Mark" and "Coach Tony".
This was the first time I had worked with LEGO NXT robots. For those not familiar with these robots, you can purchase a kit at your localtoy store. In addition to regular LEGO bricks, beams, and plates, there are motors, wheels, and sensors. A programmable NXT brick has three outputs (marked A,B, and C) to control three motors, and four inputs (marked 1,2,3,4) to receive values from sensors. Programs are written and compiled on laptops and then downloaded to the NXT programmable brick through an USB cable, or wirelessly via Bluetooth.
In the picture shown, an image of the Mars planetary surface is divided into a grid with thick black lines.A light sensor between the front two wheels of the robot is over the black line.
We used the [RobotC programming firmware] and integrated development environment (IDE) from [Carnegie Mellon University].The idea of this pilot was to see how well the students could learn "C". With only a few hours after class on each Wednesday, could we teach young students "C" programming in just seven weeks?
My contribution? I have taught both high school and college classes, and spent over 15 years programming for IBM, so Mark asked me to help.We started with a basic lesson plan:
A brief history of the "C" language
Understanding statements and syntax
Setting motor speed and direction
Compiling and downloading your first program
Understanding the "while" loop
Retrieving input sensor values
Understanding the "if-then-else" statement
Defining variables with different data types
Manipulating string variables
Writing a program for the robot to track along a black line on a white background.
Understanding local versus global scope variables
Writing a program for a robot to count black lines as it crosses them.
Perform left turns, right turns, and to cross a specific number of lines on a grid pattern to move the robot to a specific location.
Weeks 6 and 7
Mission Impossible: come up with a challenge to make the robot do something that would be difficult to accomplish using the previous NXT visual programming language.
At the completion of these seven weeks, I sat down to interview "Coach Mark"on his thoughts on this pilot project.
This is a practical programming skill. The "C" language is used throughout the world to program everything from embedded systems to operating systems, and even storage software. This would allow the robots to handle more precise movements, more accurate turns, and more complicated missions.
Can kids learn "C" in only seven weeks?
Part of the pilot project was to see how well the students could understand the material. They were already familiar with building the robots, and understood the basics of programming sensors and motors, so we were hoping this was a good foundation to work from. Some kids managed very well, others struggled.
Did everything go according to plan?
The first two weeks went well, turning on motors and having robots move forward and backward were easy enough. We seemed to lose a few students on week 3, and things got worse from there. However, several of the students truly surprised us and managed to implement very complicated missions. We were quite pleased with the results.
What kind of problems did the kids encounter?
Touch sensor required loops waiting for pressing. Motors did not necessarily turn as expected until more advanced methods were used. Making 90 degree left and right turns accurately was more difficult than expected.
Any funny surprises?
Yes, we had a Challenge Map representing the Mars planetary surface from a previous FLL competition that was dark red and divided into squares with thick black lines. An active light sensor returns a value of "0" (complete darkness) to "100" (bright white).However, the Mars surface had craters that were dark enough to be misinterpreted as a black line causing some unusual results. This required some enhanced programming techniques to resolve.
Did robots help or hurt the teaching process?
I think they helped. Rather than writing programs that just display "Hello World!" on a computer screen, the students can actually see robots move, and either do what they expect, or not!
And when the robots didn't do what they were expected to?
The students got into "debug" mode. They were already used to doing this from previous FLL competitions, but with RobotC, you can leave the USB cable connected (or use wireless Bluetooth) and actually gather debugging information while the robot is running, to see the value of sensors and other variables and help determine why things are not working properly.
Any applicability to the real world of storage?
We have robots in the IBM System Storage TS3500 tape library. These robots scan bar code labels, pull tapes out of shelves and mount them into drives.The programming skills are the same needed for storage software, suchas IBM Tivoli Storage Manager or IBM Tivoli Storage Productivity Center.
The world is becoming smarter, instrumented with sensors, interconnected over a common network, and intelligent enough to react and respond correctly. The lessons of reading sensor values and moving motors can be considered the first step in solutions that help to make a smarter planet.
This week, the [Global Language Monitor] announced that "Web 2.0" became the One Millionth word of the English language. The average American only uses about 10,000 word vocabulary.
One way to improve your vocabulary is to read my blook (blog-based book), Inside System Storage: Volume I, which includes a 900-word glossary of storage-related terms. My blook is now available in hardcover or paperback at [Amazon] as well as direct from my publisher[Lulu]:
I have started working on a new book which I hope to have available for purchase later this year.
Rather than hold this in IBM's Kirkland facility, we chose to have this instead at the [Chateau Ste. Michelle] winery, which was just a few miles away in Woodinville.
The weather was a perfect match to pair with the information we presented. Clear sky in the low 70s.
This was a typical roadshow event, serve breakfast, meet everyone, have four main-tent sessions, answer questions, then finish with a nice lunch. Here was the speaker line-up:
Jerry Mixon presented IBM Global Services to help customers improve service, reduce costs and manage risk.
Steve Loeschorn presented the latest on IBM System x and BladeCenter offerings. Steve showed how IBM'sSystem x servers were more energy efficient than x86 servers from HP and Dell.
Michael Middleton presented the latest from IBM POWER® systems. Michael had some interesting statisticsthat showed IBM's AIX operating system to be more reliable than Sun Solaris, HP-UX, andMicrosoft Windows. Based on a study of 400 companies, AIX averaged only 36 minutes of downtime per year.
Earlier this week, EMC announced its Symmetrix V-Max, following two trends in the industry:
Using Roman numerals. The "V" here is for FIVE, as this is the successor to the DMX-3 and DMX-4. EMC might have gotten the idea from IBM's success with the XIV (which does refer to the number 14, specifically the 14th class of a Talpiot program in Israel that the founders of XIV graduated from).
Adding "-Max", "-Monkey" or "2.0" at the end of things to make them sound more cool and to appeal to a younger, hipper audience. EMC might have gotten this idea from Pepsi-Max (... a taste of storage for the next generation?)
I took a cue from President Obama and waited a few days to collect my thoughts and do my homework before responding.Special thanks to fellow blogger ChuckH in giving me a [handy list of reactions] for me to pick and choose from. It appears that EMC marketing machine feels it is acceptable for their own folks to claim that EMC is doing something first, or that others are catching up to EMC, but when other vendors do likewise, then that is just pathetic or incoherent. Here are a few reactions already from fellow bloggers:
This was a major announcement for EMC, addressing many of the problems, flaws and weaknesses of the earlier DMX-3 and DMX-4 deliverables. Here's my read on this:
Now you can have as many FCP ports (128) as an IBM System Storage DS8300, although the maximum number of FICON ports is still short, and no mention of ESCON support. The Ethernet ports appear to be 1Gb, not the new 10GbE you might expect.
Support for System z mainframe
V-Max adds some new support to catch up with the DS8000, like Extended Address Volumes (EAV). EMC is still not quite there yet. IBM DS8000 continues to be the best, most feature-rich storage option if you have System z mainframe servers.
Both the IBM DS8000 and HDS USP-V beat the DMX-4 in performance, and in some cases the DMX-4 even lost to the IBM XIV, so EMC had to do something about it. EMC chooses not to participate in industry-standard performance benchmarks like those from the [Storage Performance Council], which limits them to vague comparisons against older EMC gear. I'll give EMC engineers the benefit of the doubt and say that now V-Max is now "comparably as fast as HDS and IBM offerings".
Getting "V" in the name
The "V" appears to be for the roman number five, not to be confused with external heterogeneous storage virtualization that HDS USP-V and IBM SVC provide. There is no mention of synergy with EMC's failed "Invista" product, and I see no support for attaching other vendors disk to the back of this thing.
Switch to Intel processor
Apple switched its computers from PowerPC to Intel-based, and now EMC follows in the same path. There are some custom ASICs still in V-Max, so it is not as pure as IBM's offerings.
Modular, XIV-like Scale-out Architecture
Actually, the packaging appears to follow the familiar system bays and storage bays of the DMX-4 and DMX-4 950 models, but architecturally offers XIV-like attachment across a common switch network between "engines", EMC's term for interface modules.
Non-disruptive data migration
IBM's SoFS, DR550 and GMAS have this already, as does as anything connected behind an IBM SAN Volume Controller.
A long time ago, IBM used to have midrange disk storage systems called "FAStT" which stood for Fibre Array Storage Technology, so this might have given EMC the idea for their "Fully Automated Storage Tiering" acronym. The concept appears similar to what IBM introduced back in 2007 for the Scale-Out-File Services [SofS] which not only provides policy-based placement, movement and expiration on different disk tiers, includes tape tiers as well for a complete solution. I don't see anything in the V-Max announcement that it will support tape anytime soon.
And what ever happend to EMC's Atmos? Wasn't that supposed to be EMC's new direction in storage?
Zero-data loss Three-site replication
IBM already calls this Metro/Global Mirror for its IBM DS8000 series, but EMC chose to call it SRDF/EDP for Extended Distance Protection.
Ease of Use
The most significant part of the announcement is that EMC is finally focusing on ease-of-use.In addition to reducing the requirement for "Bin File" modifications, this box has a redesigned user interface to focus on usability issues. For past DMX models, EMC customers had to either hire EMC to do tasks for them that were just to difficult otherwise, or buy expensive software like their EMC Control Center to manage. EMC willcontinue to sell DMX-4 boxes for a while, as they are probably supply-constrained on the V-Max side, but I doubt they will retro-fit these new features back to DMX-3 and DMX-4.
When IBM announced its acquisition of XIV over a year ago now, customers were knocking down our doors to get one. This caught two particular groups looking like a [deer in headlights]:
EMC Symmetrix sales force: Some of the smarter ones left EMC to go sell IBM XIV, leaving EMC short-handed and having to announce they [were hiring during their layoffs]. Obviously, a few of the smart ones stayed behind, to convince their management to build something like the V-Max.
IBM DS8000 sales force: If clients are not happy with their existing EMC Symmetrix, why don't they just buy an IBM DS8000 instead? What does XIV have that DS8000 doesn't?
Let me contrast this with the situation Microsoft Windows is currently facing.
I am often asked by friends to help them pick out laptops and personal computers. I use Linux, Windows and MacOS, so have personal experience with all three operating systems.
Linux is cheaper, offers the power-user the most options for supporting older, less-powerfulequipment, but I wouldn't have my Mom use it. While distributions like Ubuntu are makinggreat strides, it is just too difficult for some people.
MacOS is nice, I like it, it works out of the box with little or no customization and an intuitive interface. However, some of my friends don't make IBM-level salaries, and have to watch their budget.
In their "I'm a PC" campaign, Microsoft is fighting both fronts. Let's examine two commercials:
In the first commercial, a young eight-year-old puts together a video from pictures oftoy animals and some background music.The message: "Windows is easier to use than Linux!" If they really wanted to send this message, they should have shown senior citizens instead.
In the second commercial, a young college student is asked to find a laptop with 17 inchscreen, and a variety of other qualifications, for under $1000 US dollars. The only modelat the Apple store below this price had a 13 inch screen, but she finds a Windows-based system that had this size screen and met all the other qualifications. The message: "Windows-based hardware from a variety of competitors are less expensive than hardware from Apple!"
Both Microsoft and Apple charge a premium for ease-of-use.In the storage world, things are completely opposite. Vendors don't charge a premium forease-of-use. In fact, some of the easiest to use are also the least expensive.
If you just have Windows and Linux, you can get some entry level system likethe IBM DS3000 series, only a few features, and can be set up in six simple steps.
Next, if you have a more interesting mix of operating systems, Linux, Windows and some flavorsof UNIX like IBM AIX, HP-UX or Sun Solaris, then you might want the features and functionsof more pricier midrange offerings. More options means that configuration and deploymentis more difficult, however.
Finally, if you are serious Fortune 500 company, running your mission critical applications on System z or System i centralized systems in a big data center, that you might be willing to pay top dollar for the most feature-rich offerings of an Enterprise-class machine.Thankfully you have an army of highly-trained staff to handle the highest levels of complexity.
IBM's DS8000, HDS USP-V and EMC's Symmetrix are the key players in the Enterprise-classspace. They tried to be ["all things to all people"], er.. perhaps all things to allplatforms. All of the features and functions came at a price, not just in dollars, butin complexity and difficulty. You needed highly skilled storage admins using expensive storage management software, or be willing to hirethe storage vendor's premium services to get the job done.
IBM recognized this trend early. IBM's SVC, N series and now XIV all offer ease-of-use withenterprise-class features and functions, at lower total cost of ownership than traditional enterprise-class systems. IBM is not the only one, of course, as smaller storage start-ups like 3PAR,Pillar Data Systems, Compellent, and to some extent Dell's EqualLogic all recognized thisand developed clever offerings as well.
While IBM's XIV may not have been the first to introduce a modular, scale-out architectureusing commodity parts managed by sophisticated ease-of-use interfaces, its success might have been the kick-in-the-butt EMC needed to follow the rest of the industry in this direction.
An avid reader of this blog pointed me to a blog post [A Small Tec DIGG on IBM XIV], byGowri Ananthan, a System Engineer in Singapore.Basically, she covers past battles, er.. discussions between me and fellow blogger BarryB from EMC, and [blegs] foranswers to three questions.
Gowri, here are your answers:
Q1. Does IBM offer a Pay-as-you-Go [PAYGO] upgrade path for its IBM XIV disk storage system?
The concern was expressed as:
PAYGO also requires the customer to purchase the remaining capacity within 12 months of installation. So it is More of a 12-month installment plan than pay-as-you-grow.
A1. Actually, IBM offers several methods for your convenience:
With IBM's Capacity on Demand (CoD) plan, you get the full framewith 15 modules installed on your data center floor, but only pay for the first four modules 21 TB, then pay for 5.3TB module increments as you need them over the next 12 months. This is ideal for companies that don't know how fast they will grow, but do not want to wait for new modules to be delivered and installed when needed.
With IBM's Partial Rack offering, you can get a system with as little as six modules (27TB),and then over time, add more modules as you need. This does not have to be done within 12 months, you can stay at six modules for as long as you like, and you can take as long asyou want to add more modules. When you are ready for more capacity, the drawer or drawerscan be delivered, and installed non-disruptively.
Neither of these are "payment installment plans", but certainly if you want to spread yourcosts into regularly-scheduled monthlypayments across multiple years, IBM Global Financing can probably work something out.
Q2. Does IBM consider the XIV as green storage?
The concern was expressed as:
You are powering (8.4KW) and cooling all 180 drives for the whole duration, whether you're using the capacity or not. is it what you called Greener power usage..?
A2. Yes. IBM considers the IBM XIV as green storage. The 8.4KW per frame is lessthan the 10-plus KW that a comparable 2-frame EMC DMX-950 system would consume. Theenergy savings in IBM XIV comes from delivering FC-like speeds using slower SATA disks that rotate slower, and therefore take less energy to spin.
In the fully-populated or Capacity on Demand configuration, you would spin all 180disks. However, using the partial rack configuration, the 6-module has only 40 percent ofthe disks, and therefore consumes only 40 percent of the energy. If you don't plan to storeat least 20-30 TB, you might consider the DS3000, DS4000, DS5000, or DS8000 disk system instead.
Q3. How do you connect more than 24 host ports to an IBM XIV?
The concern was expressed as:
And finally do not forget my question on 24-FC Ports… Up to 24 Fiber Channel ports offering 4 Gbps, 2Gbps or 1 Gbps multi-mode and single-mode support.Stop.. stop.. how you gonna squeeze existing bunch of FC cables in 24 ports?
A3. Best practices suggest that if you have ten or more physical servers, each with two separate FC ports, then you should use a SAN switch or director in between. If you require four ports per server, then you would need a SAN switch beyond six servers to connect to the IBM XIV. If you consider that 24 FC ports, at 4Gbps, represents nearly 10 GB/sec of bandwidth, you will recognize that this is not a performance bottleneck for the system.
While the rest of Americans were glued to their televisions watching President Obama explain his plan for recovery, my colleagues and Ihad dinner with clients from Canada.
One in particular claimed her father was known as the kingpin of[Flin Flon]. She lives in Ontario now, but she grew up in this smallmining town in Manitoba made famous for winning a government contractto grow crops for medicinal purposes.
Shown at left is the town's mascott, Flinty. Yes, apparently thetown was named after a fictional character of a paperback novel.
Of course, in conversations with clients, it is best to avoid topics like politics or drugs,but the intersection of government health care and implications on IT can't be disregarded.Since Canada has a more efficient healthcare process, the government enjoys a lower costper citizen. President Obama has suggested that the United States should adopt reforms to make the American system more efficient, including electronic medical records.
Not surprisingly, [smarter healthcare] is part of IBM's latest set of strategic initiatives.Digitizing medical information has a variety of benefits:
Information isn't stranded on islands
If there is any situation that needs to deliver the right information, to the right people,at the right time, healthcare is certainly one of them. Having the right information canhelp reduce medical mistakes.
Physicians spend time with their patients, not paperwork
I personally know some doctors here in Tucson, and they are the first to admit that theywould prefer to focus on their core strengths, which they spent many years in medical school,and leave the administrative details to someone else. Focusing on core strengths is acommon theme for successful businesses, and this is no different.
Expertise needs no passport
Medical emergencies do not always happen near the hospital or clinic that your medical records are stored at.An exciting feature of digital information is that it is easy to transport to where it isneeded, unlike paper records or X-ray film.
To learn more about IBM's strategy and vision, see IBM's[Smarter Planet] Web site.
Today we watched Barack Obama get inaugurated as the 44th President of the United States, and he reminded all Americans that the power and strength of this country comes through its diversity.To some extent, this is also what gives IBM its power and strength as well. While not quite the orator of President Obama, IBM's own CFO, Mark Loughridge, gave a rousing speech about IBM's 4Q08 and year-end financial results.
In 2008, IBM was not just successful because it had a wide diversity of servers and storage hardware products, but also a diversity of software, and a diversity of service offerings.And lastly, IBM sells to a diversity of clients in different industries, throughout a diversity of markets. While the current economic meltdown might have affected businesses focused on the US and other major markets, IBM did particularly well last year in growth markets, including the so-called BRIC countries (Brazil, Russia, India and China).
IBM's approach to invest in R&D and its nearly 400,000 employees for long-term success continues to pay off. Where "Cash is King", IBM can also afford all those acquisitions and strategic initiatives, positioning the company for a brighter future.
Where there are challenges, IBM finds opportunity.
This is our so-called black-out period that prevents me from talking about how well IBM is doing or making predictions about our industry that might affect stock prices, so instead I will talk about my New Year's Resolutions.
Contribute to the OLPC Foundation
Last year, I resolved to contribute my time and effort to the One Laptop Per Child[OLPC] project led by Nicholas Negroponte. It didn't takelong for them to contact me, and I had wonderful experiences helping the folks in Nepal andUruguay.Despite building and delivering half a million laptops to deserving kids, the OLPC team has been impacted by the recent economic meltdown. From their [announcement], theOLPC team is making some shifts in their direction and priorities. Here's an excerpt:
"This restructuring is also the result of an exciting new direction for OLPC. Our technology initiatives will focus on:
Development of Generation 2.0
A no-cost connectivity program
A million digital books
Passing on the development of the Sugar Operating System to the community.
With regard to deployments:
Latin America will be spun off into a separate support unit
Sub-Saharan Africa will become a major learning hub
The Middle East, Afghanistan and Northwestern Pakistan will become a major focus"
It's not clear how involved I will be with OLPC in 2009, and I will probably wait for the dust to settle on this one.
Eat Healthier and Drink more
I hired a nutritionist and improved my diet. I also drank more (that was an easy one to keep!). Unfortunately, there is still room for improvement on this one.
Attend more movies and film-making events
I've renewed my membership with the Tucson Film Society, and attended several of their eventsin 2008, including a meeting Will Conroy, screenwriter for the Action/Suspense thriller[Transsiberian] starring Woody Harrelson and Ben Kingsley.
Get better Organized
Well I carried my [Hipster PDA] in my back pocket most of 2008, but it just did not catch on. I did get somewhat better organized, with three-ring binders and a scanner that converts paper documents into searchable PDF files.
While some might find the concept of New Year's resolutions silly or pointless, I find themuseful. Here's some interesting research on Wikipedia:
"Recent research shows that while 52 percent of participants in a resolution study were confident of success with their goals, only 12 percent actually achieved their goals. Men achieved their goal 22 percent more often when they engaged in goal setting, a system where small measurable goals are used (lose a pound a week, instead of saying "lose weight"), while women succeeded 10 percent more when they made their goals public and got support from their friends."
Here are mine for 2009:
Spend More Time with Friends and Family
According to this [article by Albrecht Powell], reconnecting with friends and family is the number one on the Top 10 list.I think the economic meltdown served as a great wake-up call for people to focus what is mostimportant in your life and adjust your priorities accordingly.
Enjoy Life More
Back in 2007, I vowed to laugh more. While the current economic crisis might not seem like an appropriate time for this one, I think there is hope, a new US President, and some much-needed enthusiasm for change.
Learn Something New
At a dinner with clients, one of the IBMers had brought his 20-something daughter and hersimilarly-aged friend. Their college was closed for the week after a student shooting, andhe felt it best to give them a change of scenery. They couldn't wait until they were "done withschool" so they could get on with their lives. I had to break the bad news to them that intoday's world, they should expect life-long learning. Gone are the days where you can learna specific skill or trade, and do that the rest of your life. Hopefully I didn't frightenboth into giving up a career in favor of marriage with such advice!
With the world getting smaller, flatter, and yes "smarter" also, I resolve to learn somethingnew. I don't necessarily know what that is yet, but I will keep it in the back of my mind.
Make Tucson a better place, and enrich the lives of its residents
I've actually gotten complaints that I was helping people in other countries, through OLPC and [Kiva],and that I should domore for people right here in Tucson. That's fair. This year I resolve to investigatethat further.
Get Better Organized
Last year was a good start, but I can certainly do better in 2009, both at home and at the office.Perhaps I need to dust off my old copy of ["Getting Things Done"] by David Allen and read it again!
It's Thursday here at the [Data Center Conference] here in Las Vegas. Trying to keep up with all the sessions and activities has been quite challenging. As is often the case, there are more sessions that I want to attend than I physically am able to, so have to pick and choose.
Making the Green Data Center a Reality
The sixth and final keynote was an expert panel session, with Mark Bramfitt from Pacific Gas and Electric [PG&E], and Mark Thiele from VMware.
Mark explained PG&E's incentive program to help data centers be more energyefficient. They have spent $7 million US dollars so far on this, and he has requested another$50 million US dollars over the next three years. One idea was to put "shells" aroundeach pod of 28 or so cabinets to funnel the hot air up to the ceiling, rather than havingthe hot air warm up the rest of the cold air supply.
The fundamental disconnect for a "green" data center is that the Facilities team pay for the electricity, but it is the IT department that makes decisions that impact its use. The PG&E rebates reward IT departments for making better decisions. The best metric available is"Power Usage Effectiveness" or [PUE], which is calculated by dividing total energy consumed in the data center, divided by energy consumed by the IT equipment itself.Typical PUE runs around 3.0 which means for every Watt used for servers, storage or network switches, another 2 Watts are used for power, cooling, and facilities. Companies are tryingto reduce their PUE down to 1.6 or so. The lower the better, and 1.0 is the ideal.The problem is that changing the data center infrastructure is as difficult as replacingthe phone system or your primary ERP application.
While California has [Title 24], stating energy efficiency standards for both residential and commercial buildings, it does notapply to data centers. PG&E is working to add data center standards into this legislation.
The two speakers also covered Data Center [bogeymans], unsubstantiated myths that prevent IT departments fromdoing the right thing. Here are a few examples:
Power cycles - some people believe that x86 servers can typically only handle up to 3000 shutdowns, and so equipment is often left running 24 hours a day to minimize these. Most equipment is kept less than 5 years (1826 days), so turning off non-essential equipment at night, and powering it back on the next morning, is well below this 3000 limit and can greatly reduce kWh.
Dust - many are so concerned about dust that they run extra air-filters which impactsthe efficiency of cooling systems air flow. New IT equipment tolerates dust much betterthan older equipment.
Humidity - Mark had a great story on this one. He said their "de-humidifier" broke,and they never got around to fixing it, and they went years without it, realizing they didn't need to de-humidify.
The session wrapped up with some "low hanging fruit", items that can provide immediate benefit with little effort:
Cold-aisle containment--Why are so few data centers doing this?
Colocation providers need to meter individual clients' energy usage -- IBM offers the instrumentation and software to make this possible
Air flow management--Simply organizing cables under the floor tiles could help this.
Virtualization and Consolidation.
High-efficiency power supplies
Managing IT from a Business Service Perspective
The "other" future of the data center is to manage it as a set of integrated IT services,rather than a collection of servers, storage and switches.IT Infrastructure Library (ITIL) is widely-accepted as a set of best practices to accomplish this "service management" approach. The presenter from ASG Software Solutions presented their Configuration Management Data Base (CMDB) and application dependency dashboard. Theyhave some customers with as many as 200,000 configuration items (CIs) in their CMDB.
The solution looked similar to the IBM Tivoli software stack presented earlier this yearat the [Pulse conference].Both ASG and IBM "eat their own dog food", or perhaps more accurately "drink their own champagne", using these software products to run their own internal IT operations.
For many, the future of a "green" data center managed as a set of integrated service are years away, but the technologies and products are available today, and there is no reasonto postpone these projects any longer than necessary. For more about IBM's approach togreen data center, see [Energy EfficiencySolutions]. You can also take IBM's[IT Service Management self-assessment] to help determine whichIBM tools you need for your situation.
Wrapping up this week's theme of thankfulness, I am thankful for theOne Laptop Per Child [OLPC] and their Get-One-Give-One (G1G1)offer.
Last November, I was one of the first to [sign up for the G1G1],and when mine arrived December 24, I posted initial observations in this[OLPC series].Over the past year, I have had the pleasure of helping out teams in Nepal and Uruguay,collaborating with developers in France, India and the United States. Giving back to othershas been a richly rewarding experience for me. I made some new friends, built up newprofessional contacts, and learned some new tricks as well.
Last year's G1G1 offer was limited to US and Canada, but this year, the OLPC have enlisted [Amazon.com] and made the offer available worldwide. You can choose to either give a single laptop for $199 USD, or get two laptops, get one for yourself or your family, and give the other to someone like Zimi, for $399 USD.
I'm thankful I did. Happy Thanksgiving to all my readers in the USA!
