Tonight I had dinner with Henry Daboub (an SVC expert from Houston, TX) and some clients, who asked what I would blog about tonight, and I figured it made sense to blog about the SVC.
Hu Yoshida clarifies his position about storage virtualization, including the statement: "As a result they can not provide the availability, scalability, and performance of a DS8300. If they could, there would be no need for a DS8300."
Of course, if humans descended from apes, why are there still apes? Now that we have cars, why are there still trains? But perhaps a better question is: now that there are supercomputers, why are there still mainframe servers?
The issue is the difference between scale-up versus scale-out. Scale-up is making a single box as big and beefy as possible. When the SVC was introduced, the major vendors all had scale-up designs: IBM ESS 800, HDS Lightning, EMC Symmetrix. Like the mainframe, they were for customers that wanted everything in a single monolithic container.
SAN Volume Controller was the result of IBM Research asking the question, if you could put anyone's software (feature and functionality) on anyone's hardware (monolithic scale-up design), what combination would you choose? What if the brains inside today's monolithic systems could be snapped into the another vendor's frame? What if you could run SRDF on an HDS box, or ShadowImage on an IBM box? The surprising response was that most customers would want a single software for consistency, but wanted the option to choose from different vendors hardware, to negotiate the best price of the commodity iron. Based on this feedback, the SVC was born.
The idea was simple, put all the brains in a separate appliance. The appliance would do the non-disruptive migrations, the caching, the striping, and all the copy services. This lets the customer chose then the hardware they want, any mix of FC and ATA disk, from any vendor.
The SVC design was based on IBM's long history in supercomputers. Using the same "scale-out" technology, the power comes not from having it all in one monolithic box, but rather in a design that combines small nodes together. While the cache is not globally shared, the data is shared between node-pairs, and the logical-to-physical mapping is routed around to all nodes in a cluster. Each SVC node talks to each other SVC node through the FCP ports, eliminating the need for additional wiring. For the most part, each node does its own separate work, but when it needs to, they can communicate across, just like nodes in a supe Both the SVC and the DS8300 Turbo have better than 99.999 percent availability, based on redundant components designed for no single point of failure (SPOF). IBM has sold thousands of each, and they have been in the field enough time that we can make that claim. There is nothing between scale-up versus scale-out that makes on inherently more available than the other. Both the SVC and the DS8300 Turbo can scale from as little as a few TB of disk, to hundreds of TB of disk. We have yet to meet a customer that is too big for the SVC. The DS8300 Turbo is able to scale by adding up to four extension frames, but is still considered a single box from a scale-up perspective. From a processor perspective, an 8-node SVC cluster has 16 Intel Xeon processors, and the DS8300 has 8 POWER5+ processors (dual 4-way). The key advantage of scale-out is that you can add capacity to the SVC in smaller increments. Jumping from a DS8100 (dual 2-way) to a DS8300 (dual 4-way) is a big jump. SVC remains the fastest disk system in the industry, based on both the SPC-1 and SPC-2 benchmarks. The latest model now supports 8GB per node, for a total of 64GB for an 8-node cluster. This can be used for both read and write non-volatile storage. By comparison, DS8300 Turbo has 32GB write non-volatile storage, and up to 256 GB of read-only cache. The SVC is able to do 155,519 IOPS, faster than the 123,030 IOPS for the DS8300, and of course faster than anything from EMC, HDS, HP or Texas Memory Systems. Of course, workloads vary, and there might be some workloads where the 256GB of read-only cache of the monolithic DS8300 is the better choice. Both SVC and DS8300 Turbo offer FlashCopy (point-in-time copy), Metro Mirror (synchronous) and Global Mirror (asynchronous). SVC provides the additional benefit that it can perform a FlashCopy from one frame to another, and the ability to migrate data seemlessly from one box to anot

Continuing my week in Chicago, for the IBM Storage Symposium 2008, I attended several sessions intended to answer the questions of the audience. In an effort to be cute, the System x team have a "Meet the xPerts" session at their System x and BladeCenter Technical Conference, so the storage side decided to do the same. Traditionally, these have been called "Birds of a Feature", "Q&A Panel", or "Free-for-All". They allow anyone to throw out a question, and have the experts in the room, either IBM, Business Partner or another client, answer the question from their experience.
Well, it's Tuesday again, and that means IBM announcements!
We've got a variety of storage-related items today, so here's my quick recap:
As people look towards deploying a dynamic infrastructure, these new offerings can be a smart fit.

It's already the 11th of January, and thought I would take a break from technology tofocus on my [New Year's Resolutions]from last year, and make some new ones for 2008.
Last Year's Resolutions:
My New Year's Resolutions for 2008:
Hopefully, this list might inspire you to come up with your own resolutions. Not surprisingly, writing them in a public forum helped me keep most of them, and stick to my resolutions throughout the year.Read More]
Well, it's Tuesday again, and we have more IBM announcements.
With the holiday season coming up at the end of the year, now is a great time to ask Santa for a new shiny pair of XIV systems, and some extra networking gear to connect them.

Continuing this week's theme on Cloud Computing, Dynamic Infrastructure and Data Center Networking, IBM unveiled details of an advanced computing system that will be able to compete with humans on Jeopardy!, America’s favorite quiz television show. Additionally, officials from Jeopardy! announced plans to produce a human vs. machine competition on the renowned show.
For nearly two years, IBM scientists have been working on a highly advanced Question Answering (QA) system, codenamed "Watson" after IBM's first president, [Thomas J. Watson]. The scientists believe that the computing system will be able to understand complex questions and answer with enough precision and speed to compete on Jeopardy!Produced by Sony Pictures Television, the trivia questions on Jeopardy! cover a broad range of topics, such as history, literature, politics, film, pop culture, and science. It poses a grand challenge for a computing system due to the variety of subject matter, the speed at which contestants must provide accurate responses, and because the clues given to contestants involve analyzing subtle meaning, irony, riddles, and other complexities at which humans excel and computers traditionally do not. Watson will incorporate massively parallel analytical capabilities and, just like human competitors, Watson will not be connected to the Internet or have any other outside assistance.
If this all sounds familiar, you might remember some of the events that have led up to this:
The research underlying Watson is expected to elevate computer intelligence and human-to-computer communication to unprecedented levels. IBM intends to apply the unique technological capabilities being developed for Watson to help clients across a wide variety of industries answer business questions quickly and accurately.

The proof-of-concept that IBM Haifa research center developed back in 1998 became what we now call the iSCSI protocol.The book iSCSI: The Universal Storage Connection introduces the history as follows:
In the fall of 1999 IBM and Cisco met to discuss the possibility of combining their SCSI-over-TCP/IP efforts. After Cisco saw IBM's demonstration of SCSI over TCP/IP, the two companies agreed to develop a proposal that would be taken to the IETF for standardization.
There are three ways to introduce iSCSI into your data center:
IBM has been delivering the first method with its successful IBM System Storage N series gateway products, buttoday we have announced additional support for the second and third methods.Here's a quick recap.
With support for Boot-over-iSCSI, diskless rack-optimized and blade servers can boot Windows or Linux over Ethe All of this is part of IBM's overall push into the Small and Medium size Business marketplace, making it easier to shop for and buy from IBM and its many IBM Business Partners, easier to deploy and install storage, and easier tomanage the storage once you have it.

Despite having business meetings every day I was here in Moscow, I managed to do a bit of sightseeing. June is a good month to visit Russia, as there are nearly 18 hours of daylight to see things. Some things are outdoors, and not constrained to normal business hours.
Near my hotel, the [Crowne Plaza at the World Trade Center], was a cute little park called "Ulista 1905 Goda". It is always nice to see large cities set aside space for nature. There were plenty of park benches to sit and enjoy. The word Ulista simply means "Street" in Russian language, and 1905 refers to the year of historical importance.
The [1905 Russian Revolution] was a wave of mass political and social unrest that spread through vast areas of the Russian Empire. It included worker strikes, peasant unrest, and military mutinies, including sailors aboard the battleship Potemkin. Alexander Adrianov became Moscow's first official mayor. The revolution led to the establishment of the State Duma of the Russian Empire, the multi-party system, and the Russian Constitution of 1906, ending the reign of Nicholas II, the last Tsar of Russia.
Walking from my hotel towards the direction of the Kremlin, I managed to find the [Old Arbat street], which has been around since the 15th century. This was considered a prestigious area of town, home to many artists, academics and politicians. Today, it is pedestrian-only, no cars allowed, with various souvenir shops and restaurants.
There is a lot to see around the Red Square to see. The [Kremlin] is a walled castle with an [Armoury Chamber] and various other cathedrals and government buildings to see inside. A ticket for the Armoury Chamber will set you back 700 rubles (about 22 bucks). [Lenin's Masoleum] is free of charge, but only open for three hours on weekdays, from 10:00am to 1:00pm, so plan accordingly.
Returning back to the hotel from the event venue on Wednesday, I walked past the [Cathedral of Christ the Saviour] on my way to the Kropotskinskaya subway station. It is actually across the river from the Red Square. Built in 1860, it is considered the tallest Orthodox church in the world at 344 feet. The domes are electroplated in gold.
I found the taxis to be ridiculously expensive here in Moscow, so I took to the subway instead. If fellow filmmaker John Waters can [hitchhike across the state of Ohio], I can certainly be adventurous and ride the Moscow Metro.
The Moscow Metro is second most used rapid transit system in the world (the first being the one in Tokyo). As a result, the subway can get quite crowded, but I found being squashed into a carload of Russian supermodels to be quite tolerable. The price is a bargain at only 28 rubles per ride (less than a dollar), with unlimited transfers.
While the Metro is a great way to get around the city, it is also a destination in itself, as the system was built in 1935 and has historical architectures that you can only see underground. At the [Ploshchad Revolyutsii station], for example, there is a whole collection of bronze statues of men and women in different work roles. For the statue of the frontier guard, many people rub the dog's nose for good luck that it has become bright and shiny.
Dispel quickly the notion that you need to eat traditional Russian food while in Moscow. A bowl of Borsch (a watery soup made from beets) and a plate of Beef Stroganof set me back 50 bucks! Apparently, restaurants know that only tourists ask for "traditional Russian food", so the prices are set accordingly.
I had to find less expensive eats to stay within my per diem meal limits. Where do the locals eat? Russia is a modern country, with plenty of Burger King, Wendy's, Baskin Robbins, Dunkin Donuts and Starbucks.
No visit to any foreign country would be complete without at least eating one meal at McDonald's. Before working for IBM, I did software engineering for McDonald's, so as a former employee, I try to visit at least one McDonald's in every country. They have restaurants in over 120 countries, so I have a ways to go yet.
A meal consisting of a "Royal" quarter-pounder with cheese, large fries and a Coke was only 214 rubles, less than seven dollars. The meat patty was medium rare, just like I make at home. You just can't get that in the States where everything has to be overcooked to avoid food-bourne illnesses. The fries were a bit over-salted, but the Coke struck just the right balance of syrup and carbonation.
Moscow is home to many museums and art galleries. The [State Tretyakov Gallery] focuses on sculptures and oil paintings from Russian artists, named after a Russian merchant who dontated his collection to get it started.
Plan a good two hours to see everything. There were many guided tour groups when I was there, which slowed me down getting through the large crowds of old people.There were over 50 rooms, with subject matter ranging from portraits, ships, and buildings, to piles of dead bodies in battle scenes. I especially liked the unique styles of [Mikhail Vrubel] and [Vasily Vereshchagin]. In many of the rooms, there were laminated placards in large-type English that explained the pieces on display.
My last stop was the [Lomonosov Moscow State University (MSU)]. This served two purposes. First, it is situated up on a hill so that you can see a great view of the rest of the city. Second, there were street vendors selling souvenirs, including the ever-popular [Matryoshka dolls], military hats, keychains, and refrigerator magnets.
In other countries, I have found going to the movies as an interesting way to see the locals in action. Foreign movies are shown here in their original language, with either Russian subtitles for the locals or headphones to hear the Russian dubbed audio track. Sadly, I did not have time to do that this week. This poster, depicting the latest Disney movie "Brave", indicates that it opens this weekend.
As always, from a sightseeing perspective, I try to leave a few things un-done, so I have reason to come back. If you know of any other exciting things to see or do in Moscow, please put that in the comments below so that I can consider it for my next trip! I would like to thank my IBM Russia colleagues Rimma Vladimirova and Sunil Bagai for their suggestions and assistance.
