It's that time again. Every year, IBM hosts the "System Storage Technical University". I have been going to these since they first started in the 1990s. This time we are at the lovely [Hilton Orlando] in Orlando, Florida.
For those who want to relive past events, here are my blog posts from this event in 2010:
As was the case last year, IBM once again will run this conference alongside the [IBM System x Technical University] the same week, in the same hotel. This allows attendees to cross over to the other side to see a few sessions of the other conference. I took advantage of this last year, and plan to do so again this year as well!

Continuing my week in Chicago for the IBM Storage and Storage Networking Symposium and System x and BladeCenter Technical Conference, I presented a variety of topics.
Hybrid Storage for a Green Data Center
The cost of power and cooling has risen to be a #1 concern among data centers. I presented the following hybrid storage solutions that combine disk with tape. These provide the best of both worlds, the high performance access time of disk with the lower costs and reduced energy consumption of tape.
IBM [System Storage DR550] - IBM's Non-erasable, Non-rewriteable (NENR) storage for archive and compliance data retention
IBM Grid Medical Archive Solution [GMAS] - IBM's multi-site grid storage for PACS applications and electronic medical records[EMR]
IBM Scale-out File Services [SoFS] - IBM's scalable NAS solution that combines a global name space with a clustered GPFS file system, serving as the ideal basis for IBM's own[Cloud Computing and Storage] offerings
Not only do these help reduce energy costs, they provide an overall lower total cost of ownership (TCO) thantraditional WORM optical or disk-only storage configurations.
The Convergence of Networks - Understanding SAN, NAS and iSCSI in the Data Center Network
This turned out to be my most popular session. Many companies are at a crossroads in choosing data and storage networking solutions in light of recent announcements from IBM and others. In the span of 75 minutes, I covered:
Block storage concepts, storage virtualization and RAID levels
File system concepts, how file systems map files to block storage
Network Attach Storage, the history of the NFS and CIFS protocols, Pros and Cons of using NAS
Storage Area Networks, the history of SAN protocols including ESCON, FICON and FCP, Pros and Cons of using SAN
IP SAN technologies, iSCSI and Fibre Channel over Ethernet (FCoE), Pros and Cons of using this approach
Network Convergence with Infiniband and Fibre Channel over Convergence Enhanced Ethernet (FCoCEE), why Infiniband was not adopted historically in the marketplace as a storage protocol, and the features and enhancements of Convergence Enhanced Ethernet (CEE) needed to merge NAS, SAN and iSCSI traffic onto a single converged data center network [DCN]
Yes, it was a lot of information to cover, but I managed to get it done on time.
IBM Tivoli Storage Productivity Center version 4.1 Overview and Update
In conferences like these, there are two types of product-level presentations. An "Overview" explains howproducts work today to those who are not familiar with it. An "Update" explains what's new in this version of the product for those who are already familiar with previous releases. I decided to combine these into one sessionfor IBM's new version of [Tivoli Storage Productivity Center].I was one of the original lead architects of this product many years ago, and was able to share many personalexperiences about its evolution in development and in the field at client facilities.Analysts have repeatedly rated IBM Productivity Center as one of the top Storage Resource Management (SRM) tools available in the marketplace.
Information Lifecycle Management (ILM) Overview
Can you believe I have been doing ILM since 1986? I was the lead architect for DFSMS which provides ILM support for z/OS mainframes. In 2003-2005, I spent 18 months in the field performingILM assessments for clients, and now there are dozens of IBM practitioners in Global Technology Services andSTG Lab Services that do this full time. This is a topic I cover frequently at the IBM Executive Briefing Center[EBC], because it addressesseveral top business challenges:
Reducing costs and simplifying management
Improving efficiency of personnel and application workloads
Managing risks and regulatory compliance
IBM has a solution based on five "entry points". The advantage of this approach is that it allows our consultants to craft the right solution to meet the specific requirements of each client situation. These entry points are:
Tiered Information Infrastructure - we don't limit ourselves to just "Tiered Storage" as storage is only part of a complete[information infrastructure] of servers,networks and storage
Storage Optimization and Virtualization - including virtual disk, virtual tape and virtual file solutions
Process Enhancement and Automation - an important part of ILM are the policies and procedures, such as IT Infrastructure Library [ITIL] best practices
Archive and Retention - space management and data retention solutions for email, database and file systems
I did not get as many attendees as I had hoped for this last one, as I was competing head-to-head in the same time slot as Lee La Frese covering IBM's DS8000 performance with Solid State Disk (SSD) drives, John Sing covering Cloud Computing and Storage with SoFS, and Eric Kern covering IBM Cloudburst.
I am glad that I was able to make all of my presentations at the beginning of the week, so that I can then sit back and enjoy the rest of the sessions as a pure attendee.
Well, I am back from Las Vegas, and had a pleasant [US Memorial Day] holiday yesterday.
Today is Tuesday, and that means more IBM announcements! IBM announced that the DCS9900 now supports an intermix of SAS and SATA drives. The DCS9900 is purpose-built specifically for the High-Performance-Computing (HPC) and Video Broadcasting industries.
The system is a combination of 4U controllers and 3U expansion drawers. The controllers handle either FC or Infiniband attachment to host servers. The expansion drawers hold up to 60 drives each. With the new features of intermix, the following drives are supported:
7200 RPM SATA drives in 500, 750 and 1000 GB capacities
15K RPM SAS drives in 146, 300 and 450 GB capacities
The DCS9900 groups the drives into sets of 10, in RAID-6 ranks of 8+2P. IBM supports either 5, 10 or 20 expansion drawers to make a complete system. The maximum configuration would be 1200 drives of the 1000GB SATA drives, for a total of 1.2 PB in two frames. Each rank must be all the same type and capacity drive, but you can mix different types within the entire system.
The DCS9900 supports "Sleep Mode", an implementation of Massive Array of Idle Disks [MAID] technology, whereby each RAID rank can be either awake and spinning, or in energy-efficient standby mode. This makes for a more "green" storage system for data that is not accessed frequently.

"Ms. Benakis, I don't want to forget the emotion of the vastness of the ocean. Draft amemo regarding this for me to sign next Monday."
-- "Yes, Mr. Morton"
"And date it as today."
-- "Yes, Mr. Morton"
On the flight home, I met Chris, a software engineer working for a small 60-person outsourcing firm in Costa Rica. He was from Vancouver, Canada but now lives in Costa Rica to avoid dealing with snow. He flies back to Canada several times per year to visit his friends and family.The irony is not lost on me that most of the tourists I met this week flew hundreds or thousands of miles to get here. The Freakonomics blog post [Did Celebrating Earth Day Make You Pollute More?] points to David Disalvo's article [Riding the Self-Regulation See Saw] and Ryan Sager'sarticle [The Al Gore’s Giant Fraggin’ Mansion Effect]. Both of these analyze environmentally moral behaviour.
The real question is whether the Earth Day lessons we learned this week from Costa Rica can apply to countries like the United States that aren't entirely focused on agriculture and tourism. Perhaps so, as Costa Rica is also home of a large [Intel plant in Heredia] that also providesa significant portion of Costa Rica's GDP.
Alternative sources of energy, including geo-thermal and hydro-electric, can provide a majorityof needs of a country. Advances in technology to take advantage of these can be carried over to other countries.
Separating our recyclables, and other efforts, are not just unique to Costa Rica. The best practices developed here can be passed on to other countries as well.
As Costa Rica experiments with green incentives to help modify human behaviour, the ones thatseem most effective can be borrowed and re-used in other locations.
Hopefully, we've all learned something this week, and perhaps can act to reduce our energy consumption and environmental impact, throughout the year, not just on Earth Day. Let's strive to make this a Smarter Planet!
Continuing this week's theme on Earth Day, I am in San José, the capital of Costa Rica.
Despite all the talk I heard about how great Costa Rica was, ranked 5th in the world as one of thegreenest countries, I had a hard time breathing the air in San José.Here's a picture I took from my hotel in Escazú, which overlooks the city.
I have been to the [Top 5 smogiest cities in the world] --Mexico City, Sao Paulo, Cairo, New Dehli, and Shanghai-- and can say that San Jose,Costa Rica is nowhere near as bad as any of those, and more on par with cities in the United States, like Pittsburgh or Los Angeles.
Having a single government official in charge of both energy and environment means they can set pricesand provide incentives in one to benefit the other. Here are two examples:
Only 5 percent of the energy consumption of this county comes from oil. Despite having their own oilrepositories off-shore, the Costa Ricans have decided not to drill and ruin their pristine shoreline,but rather import from foreign sources.Gasoline prices are set high to include some of the environmental costs, about four dollars per gallon(800 Costa Rican Colones per liter). Cars can be converted to run on less expensive Propane orsugar cane Ethanol, but the conversions are cost-prohibitive for many.
Did it help? No, Traffic was like a parking lot. Part of this was the result of the main highway beingunder construction, forcing many people to take side streets.
Electricity is 13 US cents per KWh. My hotel in Escazu wanted an extra $8.50 US dollars per day to run theAir Conditioner. By comparison, my house in Tucson, Arizona is 1167 square feet, roughly five to six times the size of my hotel room, and my electricity bill is a flat 27 US dollars per month year round.
Did it help? No, most tourists just pay the extra cost. I tried one day with A/C, and the second day without, for scientific comparison, and decided to go without the rest of the time I was there. Perhaps being from Tucson, Arizona I can tolerate the 85-degree heat better than others.
So if incentives to conserve like high prices don't work, what will? I interviewed Alexandra,a local 24-year-old studying law at a nearby college:
Once you get your law degree, will you move to another country, such as the United States? --There are already too many lawyers in your country.
What about Japan or Asia, there is a shortage of lawyers there?-- No, I plan to stay here in my country. Costa Rica is beautiful, my friends and family are here, why would I leave?
So why do you think the incentives don't work to help people conserve gasoline and electricity? --People have to earn a living, and are focused on getting things done. If it can be done in a way that helps the environment, great, but otherwise life continues.
So will you specialize in "environmental" law? -- Not sure yet. Too early to say. Costa Rica is certainly leading the world in environmental protection, and much of this is through laws and tax schemes.
High prices don't serve well as incentives to reduce consumption, but perhaps national pride and working in an industry like agriculture or eco-tourism might.
