Finishing off this week's series of Pulse 2009 videos, I wrap up with a video on IBM's exciting data deduplication appliance.
The awards will be announced on Tuesday, April 7th at the event during the General Session:
10:00-10:15 am "Best Practices in Storage" Awards Program
Of course, I'll be rooting for the one above that used IBM's XIV disk storage system to reduce their energy consumption, improve their utilization, and simplify their management.Read More]
I am proud to announce that fellow IBMer Carlos Pratt has launched a new IBM storage blog[GreenSpeed].
I'd like to expand a bit on how I know Carlos. Back in 1999 I was asked to lead a team at IBM Tucson to install Linux on our local z800 mainframe, and run tests to confirm that all of our IBM disk and tape storage offerings attached successfully. I was, at the time, lead architect for DFSMS on OS/390 and management felt that my knowledge of the S/390 instruction set was all that was needed to pull this off. My team was a collection of people from a variety of other hardware and software teams, and Carlos came over from the Disk Performance test team.
Needless to say, there were some challenges. The port of Red Hat and SUSE Linux over to the mainframe required special device drivers, and in some cases, we actually needed to make changes to the Linux kernel. While it was over 100 degrees outside, we were in the test lab wearing jackets with a refrigerator thermometer hanging on the wall to monitor our ice cold working conditions.
And of course, we had our internal skeptics. At the time, Linux was only a few percentage points of marketshare, and a few unenlightened souls did not see any reason to invest in support for a new operating system until it was more established. People with a "Wait-and-See" attitude don't last long at IBM. Fortunately, smarter heads prevailed, and now that Linux is well established as the operating system of the future, we can all look back and say "I told you so!"
Carlos was a "get things done" kind of guy. Working with frequent patches to the Linux kernel, device drivers under development, and a team fairly new to this new operating system, Carlos was able to provide the driving force to get our tests done.
So, please check out Carlos' new blog!Read More]

Well, it is Tuesday, and that means IBM announcements. This week many of my colleagues are attending Storage Networking World [SNW] conference. Normally, the most exciting announcements are reserved for the weeks these conferences are held, but IBM apparently made an exception this week.
If you are at SNW this week, stop by and say "Hi" to my fellow IBM collegues for me.
Did you miss your chance to attend Storage Networking World last week? IBM has some upcoming conferences that might be of interest to you.
Hopefully, this will give you enough time to plan and make travel arrangements!Read More]

Earlier this week, EMC announced its Symmetrix V-Max, following two trends in the industry:
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:
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]:

This week, I am in Costa Rica to blog about "Earth Day" which officially is this Wednesday, April 22.
Fellow published author Thomas Friedman has a book titled[Hot, Flat, and Crowded: Why We Need a Green Revolution - and How It Can Renew America] which serves as a call to action for Americans. His recent op-ed piece in the New York Times newspaper, titled [(No) Drill, Baby, Drill] is all about Costa Rica. Here is an excerpt:
"These days, visitors can still see amazing biodiversity all over Costa Rica — more than 25 percent of the country is protected area — thanks to a unique system it set up to preserve its cornucopia of plants and animals. Many countries could learn a lot from this system.
At the [Springs Resort and Spa], they have clear (chlorinated) swimming pools maintained at three different temperatures. I asked our guide,Alan, if the pools were being heated from the electricity generated from the dam at the lake.No, they use green water for green energy. Taking advantage of "geo-thermal" energy, the natural hot springs are run through a [Heat Exchanger], to heat the pools. The waters do not mix, keeping the clean water clean. The process is similar to IBM's [Rear Door Heat eXchanger].
Fortunately, I speak the Castellano dialect of Spanish that is spoken here in Costa Rica,and this will allow me to continue to gather more information about how Costa Rica leads the way in being more energy efficient and environmentally responsible.
This week's theme is Earth Day and the importance IBM has placed on energy and environmental conservation. I am traveling through Costa Rica, ranked by Forbes as the fifth greenest and [cleanest countries in the world]. Europe was home to the top four in the survey of 149 countries, ledby Switzerland, and home to 14 of the top 20. Colombia came in ninth. United States was a pathetic 39th.
In yesterday's post, [Green Water for Green Energy], I covered geo-thermal energy with a visit to the hot springs.My next activity was a rafting trip down the Peñas Blancas and San Carlos rivers, heading towards Nicaragua, to discuss hydro-electric power. Half of the hydro-electric power in this country is driven directly by river flow, and the rest relies on stored water in lakes. Back in 2007, Costa Rica had a drought, and this affected the hydro-electric capacity, resulting in brown-outs and power outages. When more than 80 percent of your energy comes from this source, droughts can be devastating. Rain patterns for Costa Rica have a dry season from mid-December to April, lots of Rain in May and June, a "short summer" (called affectionately El Veranito) with little or no rain in July, and then more rain the rest of the year, averaging over 150 inches of rainfall per year.
This was billed as a "Safari Float" ride.The water level was low, "Class I", the slowest possible rating, giving our raft guide Pedro a chance to point out a variety of birds, monkeys, iguanas and crocodiles. Iguanas and Crocodiles are protected endangered species in Costa Rica, and are notsupposed to be killed for food or sport.
(Hint: don't bother, both taste like chicken)Joining us in our raft is Pamela, the 9-year-old daughter of one of the employees of the rafting company, [Canoa Adventura]. This wastheir version of take
Along the way, we saw a bulldozer knocking down trees and scooping up the rich soil.Costa Ricans consider trees and soil as renewable resources, reducing the need to purchase foreign fossil-based oil for cooking and chemical fertilizers.The name of the country, Costa Rica, literally means "rich coast" in the Spanish language, and with a string of 112 volcanos, the silt has plenty of mineral content that is good for agriculture, from coffee and bananas, to sugar cane, oranges and African palm.
Midway down the river, we had an "energy stop" to rest from all the paddling. This involved a visit to Don Pedro's farm, he is 98 years old, has four daughters, five grandchildren, and three grea On the ride back, we stopped at the famous "Iguana bridge" where we could see up close and personal a dozen or so of these huge lizards.

Happy Earth Day everyone!
This week I am in Costa Rica to celebrate[Earth Day] and promote IBM's [Smarter Planet strategy] to help solve the world's energy and environmental problems. This is thethird in the series. The first two posts were:
Most people are familiar with the [star rating system] that rank most hotels from one star (budget class/economy) to five stars (deluxe/luxury). The nicest hotel I've been to was the [Burj Al Arab] in Dubai, which claims a seven star rating. For eco-tourism, there is a similar "Green Leaf" rating system. According to Patrick,the Instituto Costarricense de Turismo [ICT] (tourism board of Costa Rica) rates hotels from one leaf (adopting some measures, like separating recyclables shown above) to five leaves (entirely carbon neutral).This Green Leaf system seems more important to European and Canadian tourists, but those from United States may not even be aware of it.
The food at these hotels vary. The typical dish here for breakfast, lunch and dinner is the Casado, consisting of mostly rice and beans. I have found thatCosta Rica has come up with as many creative ways to combine rice and beans in various proportions as Starbucks® serve various combinations of coffee and milk.The locals might be accustomed to a steady diet of rice and beans for every meal of every day, but those of us from North America aren't! Not counting tourist flatulence, Costa Rica has[pledged to be carbon neutral by 2021], the country's 200th birthday.
Sadly, most folks in the United States don't categorize their hotels with a Green Leaf rating system, nor do they even bother to categorize their recyclables. I spent 18 months in the field doing Information Lifecycle Management (ILM) assessments for clients, and most didn't categorize their data either.So, the next time you have some combination of coffee and milk, whether its a Latte, Misto, Espresso, or Macchiato, remember that the coffee came from acountry trying to be more environmentally responsible, grown by a farmerwho eats a simple diet of rice and beans, and has no problem separating different categories of recyclables. Perhaps you will remember to separate your data, and store it on an information infrastructure based on an envi We're all on this planet together.
We're all on this planet together.
Continuing this week's theme on Earth Day, I am in San José, the capital of Costa Rica.
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:
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:
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.
Wrapping up this week's theme on Earth Day, I head back home. This is the fifth in a series.The rest of the series discussed [Geo-thermal energy], [Hydro-electic power], the [Green Leaf rating system], and[Green Incentives].
First, let's start with an excerpt from El Naccional, by cartoonist Quino:
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.
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!
This week's theme is alternative sourcing through Cloud Computing.
TFA has been in business since 1997, and has six employees, including an office manager, event planners and event coordinators.
It's very important in several ways.First, the TFA staff plans 25 events per month, and our hundreds of members register for these events mostly through the Web site. Second, we have it connected to our bank accounts, so that it can process credit cards to collect the funds for renewals and event regi
Our members were complaining about our 1999-era Web site. The pages were written in HTML, ASP (Active Service Page) and SQL (Structured Query Language) connected to a Microsoft SQL Server 2005 database. It was mostly text-based, with the only animation being text scrolling horizontally across the screen. The Web hostingprovider offered reliable access, but was located in New York state on East Coast time. If a member signed up for an event after 9pm or 10pm here in Tucson, it was marked as the next date, which could change the price of the event, or indicate the deadline was missed.If there were any changes to the pages or logic needed, or new columns required in the database, it gotexpensive. The TFA employees don't know how to program in ASP or SQL, so we hadto hire outside professionals each time.
Hopefully, this provides some insight on how even the smallest SMB enterprises can adopt a Dynamic Infrastructure through alternative sourcing. Cloud Computing takes many forms, including Soft

It's Tuesday, which means IBM announcements, and today IBM made some major announcementsthat support a [Dynamic Infrastructure]! I hinted at this yesterday, choosing the week's theme to be all about Cloud Computing and Alternative Sourcing. I will briefly highlight today's announcements related to storage here, and try to go into more detail over the next few weeks.
This is just a small subset of all the announcements. For more information, see this 28-pagepresentation [Manage the Explosion of Information with IBM Information Infrastructure].

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.

Wrapping up this week's theme on Cloud Computing, I finish with an IBM announcement for two new products to help clients build private cloud environments from their existing Service Oriented Architecture (SOA) deployments.
With more than 7,000 customer implementations worldwide, IBM is the SOA market leader. Of course, both of these products above can be used with IBM System Storage solutions, including Cloud-Optimized Storage offerings like Grid Medical Archive Solution (GMAS), Grid Access Manager software, Scale-Out File Services (SoFS), and the IBM XIV disk system.
IBM is part of the "Cloud Computing 5" major vendors pushing the envelope (the other four are Google, Microsoft, Amazon and Yahoo). In fact, IBM has a number of initiatives that allow customers to leverage IBM software in a cloud. IBM is working in collaboration with Amazon Web Services (AWS), a subsidiary of Amazon.com, Inc. to make IBM software available in the Amazon Elastic Compute Cloud (Amazon EC2). WebSphere sMash, Informix Dynamic Server, DB2, and WebSphere Portal with Lotus Web Content Management Standard Edition are available today through a "pay as you go" model for both development and production instances. In addition to those products, IBM is also announcing the availability of IBM Mashup Center and Lotus Forms Turbo for development and test use in Amazon EC2, and intends to add WebSphere Application Server and WebSphere eXtreme Scale to these offerings.

Looks like fellow blogger and arch nemesis BarryB from EMC is once again stirring up trouble, this time he focuses his attention on IBM's leadership in Solid State Disk (SSD) on the IBM System Storage DS8000 disk systems in his post [IBM's amazing splash dance, part deux], a follow-up to [IBM's amazing splash dance] and multi-vendor tirade [don't miss the amazing vendor flash dance].
(Note: IBM [Guidelines] prevent me from picking blogfights, so this post is only to set the record straight on some misunderstandings, point to some positive press about IBM's leadership in this area, and for me to provide a different point of view.)
First, let's set the record straight on a few things. The [RedPaper is still in draft form] under review, and so some information has not yet been updated to reflect the current situation.
I find it amusing that BarryB's basic argument is that IBM's initial release of SSD disk on DS8000 is less than what the potential architecture could be extended to support much more. Actually, if you look at EMC's November release of Atmos, as well as their most recent announcement of V-Max, they basically say the same thing "Stay Tuned, this is just our initial release, with various restrictions and limitations, but more will follow." Architecturally, IBM DS8000 could support a mix of SSD and non-SSD on the same DA pairs, could support RAID6 and RAID10 as well, and could support larger capacity drives or use higher-capacity read-intensive formats. These could all be done via RPQ if needed, or in a follow-on release.
BarryB's second argument is that IBM is somehow "throwing cold water" on SSD technology. That somehow IBM is trying to discourage people from using SSD by offering disk systems with this technology. IBM offered SSD storage on BladeCenter servers LONG BEFORE any EMC disk system offering, and IBM continues to innovate in ways that allow the best business value of this new technology. Take for example this 24-page IBM Technical Brief:[IBM System z® and System Storage DS8000:Accelerating the SAP® Deposits Management Workload With Solid State Drives]. It is full of example configurations that show that SSD on IBM DS8000 can help in practical business applications. IBM takes a solution view, and worked with DB2, DFSMS, z/OS, High Performance FICON (zHPF), and down the stack to optimize performance to provide real business value innovation. Thanks to this synergy,IBM can provide 90 percent of the performance improvement with only 10 percent of the SSD disk capacity as EMC offerings. Now that's innovative!
The price and performance differences between FC and SATA (what EMC was mostly used to) is only 30-50 percent. But the price and performance differences between SSD and HDD is more than an order of magnitude in some cases 10-30x, similar to the differences between HDD and tape. Of course, if you want hybrid solutions that take best advantage of SSD+HDD, it makes more sense to go to IBM, the leading storage vendor that has been doing HDD+Tape hybrid solutions for the past 30 years. IBM understands this better, and has more experience dealing with these orders of magnitude than EMC.
But don't just take my word for it. Here is an excerpt from Jim Handy, from [Objective Analysis] market research firm, in a recent Weekly Review from [Pund-IT] (Volume 5, Issue 23--May 6, 2009):
As for why STEC put out a press release on their own this week without a corresponding IBM press release, I can only say that IBM already announced all of this support back in February, and I blogged about it in my post [Dynamic Infrastructure - Disk Announcements 1Q09]. This is not the first time one of IBM's suppliers has tried to drum up business in this manner. Intel often funds promotions for IBM System x servers (the leading Intel-based servers in the industry) to help drive more business for their Xeon processor.
So, BarryB, perhaps its time for you to take out your green pen and work up another one of your all-too-common retraction and corrections.[Read More]

My post last week [Solid State Disk on DS8000 Disk Systems] kicked up some dust in the comment section.Fellow blogger BarryB (a member of the elite [Anti-Social Media gang from EMC]) tried to imply that 200GB solid state disk (SSD) drives were different or better than the 146GB drives used in IBM System Storage DS8000 disk systems. I pointed out that they are the actual same physical drive, just formatted differently.
To explain the difference, I will first have to go back to regular spinning Hard Disk Drives (HDD). There are variances in manufacturing, so how do you make sure that a spinning disk has AT LEAST the amount of space you are selling it as? The solution is to include extra. This is the same way that rice, flour, and a variety of other commodities are sold. Legally, if it says you are buying a pound or kilo of flour, then it must be AT LEAST that much to be legal labeling. Including some extra is a safe way to comply with the law. In the case of disk capacity, having some spare capacity and the means to use it follows the same general concept.
(Disk capacity is measured in multiples of 1000, in this case a Gigabyte (GB) = 1,000,000,000 bytes, not to be confused with [Gibibyte (GiB)] = 1,073,741,824 bytes, based on multiples of 1024.)
Let's say a manufacturer plans to sell 146GB HDD. We know that in some cases there might be bad sectors on the disk that won't accept written data on day 1, and there are other marginally-bad sectors that might fail to accept written data a few years later, after wear and tear. A manufacturer might design a 156GB drive with 10GB of spare capacity and format this with a defective-sector table that redirects reads/writes of known bad sectors to good ones. When a bad sector is discovered, it is added to the table, and a new sector is assigned out of the spare capacity.Over time, the amount of space that a drive can store diminishes year after year, and once it drops below its rated capacity, it fails to meet its legal requirements. Based on averages of manufacturing runs and material variances, these could then be sold as 146GB drives, with a life expectancy of 3-5 years.
With Solid State Disk, the technology requires a lot of tricks and techniques to stay above the rated capacity. For example, you can format a 256GB drive as a conservative 146GB usable, with an additional 110GB (75 percent) spare capacity to handle all of the wear-leveling. You could lose up to 22GB of cells per year, and still have the rated capacity for the full five-year life expectancy.
Alternatively, you could take a more aggressive format, say 200GB usable, with only 56GB (28 percent) of spare capacity. If you lost 22GB of cells per year, then sometime during the third year, hopefully under warranty, your vendor could replace the drive with a fresh new one, and it should last the rest of the five year time frame. The failed drive, having 190GB or so usable capacity, could then be re-issued legally as a refurbished 146GB drive to someone else.
The wear and tear on SSD happens mostly during erase-write cycles, so for read-intensive workloads, such as boot disks for operating system images, the aggressive 200GB format might be fine, and might last the full five years.For traditional business applications (70 percent read, 30 percent write) or more write-intensive workloads, IBM feels the more conservative 146GB format is a safer bet.
This should be of no surprise to anyone. When it comes to the safety, security and integrity of our client's data, IBM has always emphasized the conservative approach.[Read More]
Recently, IBM and the University of Texas Medical Branch (UTMB) [launched an effort] using IBM's World Community Grid "virtual supercomputer" to allow laboratory tests on drug candidates for drug-resistant influenza strains and new strains, such as H1N1 (aka "swineflu"), in less than a month.
Researchers at the University of Texas Medical Branch will use [World Community Grid] to identify the chemical compounds most likely to stop the spread of the influenza viruses and begin testing these under laboratory conditions. The computational work adds up to thousands of years of computer time which will be compressed into just months using World Community Grid. As many as 10 percent of the drug candidates identified by calculations on World Community Grid are likely to show antiviral activity in the laboratory and move to further testing.
According to the researchers, without access to World Community Grid's virtual super computing power, the search for drug candidates would take a prohibitive amount of time and laboratory testing.
A few months after Larry's "call to action" in 2006, IBM and over twenty major worldwide public health institutions, including the World Health Organization [WHO] and the Centers for Disease Control and Prevention [CDC], [announced the Global Pandemic Initiative], a collaborative effort to help stem the spread of infectious diseases.
One might think that with our proximity to Mexico that the first cases would have been the border states, such as Arizona, but instead there were cases as far away as New York and Florida. The NYT explains in an article [Predicting Flu With the Aid of (George) Washington] that two rival universities, Northwestern University and Indiana University, both predicted that there would be about 2500 cases in the United States, based on air traffic control flight patterns, and the tracking data from a Web site called ["Where's George"] which tracks the movement of US dollar bills stamped with the Web site URL.
The estimates were fairly close. According to the Centers for Disease Control and Prevention [H1N1 Flu virus tracking page], there are currently 3009 cases of H1N1 in 45 states, as of this writing.
This is just another example on how an information infrastructure, used properly to provide insight, make predictions, and analyze potential cures, can help the world be a smarter planet. Fortunately, IBM is leading the way.Read More]

Continuing my ongoing discussion on Solid State Disk (SSD), fellow blogger BarryB (EMC) points out in his [latest post]:
Oh – and for the record TonyP, I don't think I ever said EMC was using a newer or different EFDs than IBM. I just asserted that EMC knows more than IBM about these EFDs and how they actually work a storage array under real-world workloads.
(Here "EFD" is refers to "Enterprise Flash Drive", EMC's marketing term for Single Layer Cell (SLC) NAND Flash non-volatile solid-state storage devices. Both IBM and EMC have been selling solid-state storage for quite some time now, but EMC felt that a new term was required to distinguish the SLC NAND Flash devices sold in their disk systems from solid-state devices sold in laptops or blade servers. The rest of the industry, including IBM, continues to use the term SSD to refer to these same SLC NAND Flash devices that EMC is referring to.)
The disagreement resulted from his earlier statement from his post[IBM's amazing...part deux]:
Although STEC asserts that IBM is using the latest ZeusIOPS drives, IBM is only offering the 73GB and 146GB STEC drives (EMC is shipping the latest ZeusIOPS drives in 200GB and 400GB capacities for DMX4 and V-Max, affording customers a lower $/GB, higher density and lower power/footprint per usable GB.)
Here is where I enjoy the subtleties between marketing and engineering. Does the above seem like he is saying EMC is using newer or different drives? What are typical readers expected to infer from the statement above?
Uncontested, some readers might infer the above and come to the wrong conclusions. I made an effort to set the record straight. I'll summarize with a simple table:
So, we all agree now that the 256GB drives that are formatted as 146GB or 200GB are in fact the same drives, that IBM and EMC both sell the latest drives offered by STEC, and that the STEC press release was in fact correct in its claims.
I also wanted to emphasize that IBM chose the more conservative format on purpose. BarryB [did the math himself] and proved my key points:
I agree with BarryB that an aggressive format can offer a lower $/GB than the conservative format. Cost-conscious consumers often look for less-expensive alternatives, and are often willing to accept less-reliable or shorter life expectancy as a trade-off. However, "cost-conscious" is not the typical EMC targeted customer, who often pay a premiumfor the EMC label. To compensate, EMC offers RAID-6 and RAID-10 configurations to provide added protection. With a conservative format, RAID-5 provides sufficient protection.
(Just so BarryB won't accuse me of not doing my own math, a 7+P RAID-5 using conservative format 146GB drives would provide 1022GB of capacity, versus 4+4 RAID-10 configuration using aggressive format 200GB drives only 800GB total.)
In an ideal world, you the consumer would know exactly how many IOPS your application will generate over the next five years, exactly how much capacity you will require, be offered all three drives in either format to choose from, and make a smart business decision. Nothing, however, is ever this simple in IT.Read More]

Wrapping up my week in Seattle, Washington, I presented at a[Dynamic Infrastructure] client event. This is the third one in a six-city tour. I will not be at the remaining cities next week, as I will be at the [Forrester IT Forum 2009 Conference] instead in Las Vegas, Nevada.
