This is the shortest presentation I’ve seen and most pragmatic about what SSDs can do for you. He recommends buying Intel 320s and getting your feet wet by moving from a bicycle to a Ferrari. Later on if you need to go with a PCIe SSD do it, but it’s like the difference between a Formula 1 race car and a Ferrari. Personally in spite of the lack of major difference Artur is trying to illustrate I still like the idea of buying once and getting more than you need. And if this doesn’t start you down the road of seriously buying SSDs of some sort check out this interview with Violin Memory CEO, Don Bazile:
Violin tunes up for billion dollar flash gig: Chris Mellor@theregister.co.uk (Saturday June 25th)
Basile said: “Larry is telling people to use flash … That’s the fundamental shift in the industry. … Customers know their competitors will adopt the technology. Will they be first, second or last in their industry to do so? … It will happen and happen relatively quickly. It’s not just speed; its the lowest cost of data base transaction in history. [Flash] is faster and cheaper on the exact same software. It’s a no-brainer.”
Violin Memory is the current market leader in data center SSD installations for transactional data or analytical processing. The boost folks are getting from putting the databases on Violin Memory boxes is automatic, requires very little tuning and the results are just flat out astounding. The ‘Larry’ quoted above is the Larry Ellison of Oracle, the giant database maker. So with that kind of praise I’m going to say the tipping point is near, but please read the article. Chris Mellor lays out a pretty detailed future of evolution in SSD sales and new product development. 3-bit Multi-Level memory cells in NAND flash is what Mellor thinks will be the tipping point as price is still the biggest sticking point for anyone responsible for bidding on new storage system installs. However while that price sticking point is a bigger issue for batch oriented off-line data warehouse analysis, for online streaming analysis SSD is cheaper per byte per second throughput. So depending on the typical style of database work you do or performance you need SSD is putting the big iron spinning hard disk vendors to shame. The inertia of these big capital outlays and cozy relationships with these vendors will make some shops harder to adopt the new technology (But IBM is giving us such a big discount!…WE are an EMC shop,etc.). However the competitors of the folks owning those datacenters will soon eat all that low hanging fruit a simple cutover to SSDs will afford and the competitive advantage will swing to the early adopters.
*Late Note: Chris Mellor just followed up Monday night (June 27th) with an editorial further laying out the challenge to disk storage presented by the data center Flash Array vendors. Check it out:
What should the disk drive array vendors do, if this scenario plays out?They should buy in or develop their own all-flash array technology. Having a tier of SSD storage in a disk drive array is a good start but customers will want the simpler choice of an all-flash array and, anyway, they are here now. Guys like Violin and Whiptail and TMS are knocking on the storage array vendors customer doors right now.
