Solid State Disk
Its been a crazy last few years in the flash storage space. Things really started taking off around 2006 when NAND flash and moores law got together. in 2010 it was clear that flash storage was going to be a major part of your storage makeup in the future. It may not be NAND flash specifically though. It will be some kind of memory and not spinning disks.Breaking The Cost Barrier.
For the last few years, I’ve always told people to price out on the cost of IO not the cost of storage. Buying flash storage was mainly a niche product solving a niche problem like to speed up More >
Not to sound too obvious, I test IO systems. That means from time to time I have to refresh my environment if I want to test current hardware. Like you, I work for a living and can’t afford something like a Dell R910 Heck, I can’t afford to shell out for the stuff that Glenn Berry gets to play with these days. Yes, I work for the mighty Dell. No, they don’t give me loads of free hardware to just play with. That doesn’t mean I, or you, can’t have a solid test system that is expandable and a good platform for testing SQL Server.The hardware choices, inexpensive More >
Thanks again to everyone who attended. Technical problems aside I had a great time and there were some great questions!
If you have a question please feel free to contact me, I’ll do my best to answer it.
If you have been reading my storage series, and in particular my section on solid state storage, you know I have a pretty rigid standard for enterprise storage. Several months ago I contacted Pliant Technology about their Enterprise Flash Drives. It didn’t surprise me when they made the recent announcement about being acquired by SanDisk. Between Pliants’ enterprise ready technology and SandDisks’ track record at the consumer level I think they will be a new force to be reckoned with for sure. Pliant drives are already being sold by Dell and now will More >
Knowing when a technology is dying is always a good skill to have. Like most of my generation we weren’t the first on the computer scene but lived through several of it’s more painful transitions. As a college student I was forced to learn antiquated technologies and languages. I had to take a semester of COBOL. I also had to take two years of assembler for the IBM 390 mainframe and another year of assembler for the x86 focused on the i386 when the Pentium was already on the market. Again and again I’ve been forced to invest time in dying technologies. Well not any More >

I try and keep this quote in my mind whenever I’m teaching about new technologies. You often hear the same things parroted over and over again long after they quit being true. This problem is compounded by fast moving technologies like NAND Flash.
If you have read my previous posts about Flash memory you are already aware of NAND flash endurance and reliability. Just like CPU’s manufacturing processes flash receive boost in capacity as you decrease the size of the More >
We are in the final stages of selecting the speakers for the SQLRally May 11th through the 13th in sunny Orlando Florida. The program selection is a little different than what we have done with the Summit. The committee narrowed the number of selections and is putting the rest up to a public vote. This is your opportunity to voice your opinion on what you would like to hear at this inaugural event! I’ve been fortunate enough to have two of my sessions put up for a vote. If you follow my blog you know I have a passion for moving bits of data around as fast as possible. Both my sessions focus More >
Fusion-io has announced general availability of the new Octal. This card is the largest single flash based device I’ve ever seen. The SLC version has 2.56 terabytes of raw storage and the MLC has a whopping 5.12 terabytes of raw storage. This thing is a behemoth. The throughput numbers are also impressive, both read at 6.2 Gigabytes a second using a 64KB block, you know the same size as an extent in SQL Server. They also put up impressive write numbers the SLC version doing 6 Gigabytes a second and the MCL clocks in at 4.4 Gigabytes a second.
There is a market for these drives but you really More >
I recently wrote about solid state storage and its different form factor. Well, several major manufacturers have realized that solid state needs all the bandwidth it can get. Dell, IBM, EMC, Fujitsu and Intel have formed the SSD Form Factor Working Group bringing PCIe 3 to the same form factor that SATA and SAS use. Focusing on the same connector types and a 2.5” dive housing. I’m not sure how quickly it will make it’s way into the enterprise space but that is clearly it’s target. Reusing the physical form factor cuts down on manufacturing and R&D costs for all involved. They have an More >
Solid state storage has come on strong in the last year. With that explosion of new products it can be hard to look at all the vendor information and decide which device is best for you. Between the different manufacturers using different methods to benchmark their products showing two different numbers for reads and writes using different methodologies it can be extremely confusing. If you haven’t read Solid State Storage Basics you may not understand all the terms used in this article.SLC and MLC Characteristics and Differences
Right now there are two main flavors of NAND Flash that are in More >
