I was poking around again and came across a new product from Fusion IO which looked really cool. Their new Iodrive Octal, which packs 800,000 IOPS on a single card with 6 Gigabytes/second sustained bandwidth. To put this in perspective, a typical high end 15,000 RPM SAS/Fiber Channel disk drive can do about 250 IOPS. As far as I/O goes this is roughly the same as 3,200 drives. The densest high performance storage I know of is 3PAR who can pack 320 15,000 RPM drives in a rack in their S-class and T-class systems (others can do high density SATA, I’m not personally aware of others that can do high density 15,000 RPM drives for online data processing).
But anyways, in 3PAR’s case that is 10 racks of drives, and three more racks for disk controllers(24 controllers), roughly 25,000 pounds of equipment(performance wise) in the palm of your hand with the Iodrive Octal. Most other storage arrays top out at between 200 and 225 disks per rack.
The Fusion IO solutions aren’t for everyone of course they are targeted mostly at specialized applications with smaller data sets that require massive amounts of I/O. Or those that are able to distribute their applications amongst several systems using their PCIe cards.
