Are RAID Controllers the Next Data Center Bottleneck?

storagedude writes "This article suggests that most RAID controllers are completely unprepared for solid state drives and parallel file systems, all but guaranteeing another I/O bottleneck in data centers and another round of fixes and upgrades. What's more, some unnamed RAID vendors don't seem to even want to hear about the problem. Quoting: 'Common wisdom has held until now that I/O is random. This may have been true for many applications and file system allocation methodologies in the recent past, but with new file system allocation methods, pNFS and most importantly SSDs, the world as we know it is changing fast. RAID storage vendors who say that IOPS are all that matters for their controllers will be wrong within the next 18 months, if they aren't already.'"

Running a nagios application to poll our switchports for utilization, the average host is running maybe 20% utilization of the link speed

You sound gay.
