Re: SAS 5/IR Performance

Hi The Taltos,
  SAS 5/i is not a hardware RAID, it's depending on the O/S to provide the RAID functionality, you're experiancing the reason we offer hardware RAID: to offload handling the RAID arrays to a special purpose processor on the RAID controller.
  Look at your performance monitor you're getting processor bound, you might also want to look at the page file settings
