SSDs, pNFS Will Test RAID Controller Design

Article Source Enterprise Storage Forum

RAID controllers designed for hard disks and IOPS aren't going to cut it in the new world of solid state drives (SSDs) and pNFS, which are capable of feeding so much more data into the channel that streaming bandwidth is going to become the problem for RAID vendors.

RAID vendors look at me like I'm nuts when I say this. Data storage is an IOPS world, they say, so why should I care about streaming performance? For those of you who don't know, IOPS is the number of I/O requests per second, while streaming bandwidth is how many gigabytes per second the controller can deliver to a server or servers...
