Are you referring to the array controller or the HGS80 controller?

RE: Slow performance
I believe he was referring to a SAN configuration - and yes, MS does not recommend using large raid 5 sets on a SAN. Raid 10 is the preferred method. Exchange 2k writes in small 4k blocks. Using raid 10 with 15K drives would really up the performance. It also matters how the data files are broken up in Exchange. If you email me directly I can provide some performance counters which can help pinpoint the bottle neck.

RE: Slow performance
Purely from an Exchange I/O perspective, given the choice between 500MB of RAID10 storage built out of 72GB drives (16 of them roughly) and 500MB of RAID10 storage built out of 18GB drives (64 of them roughly), the 18GB drive setup will be measurably faster than the other. A higher number of smaller spindles will benefit performance. Adjusting your design to optimize more toward the money axis will cost performance. Also remember that many of the E2K white papers were written before 72GB drives were commonly available. Just because the common size is now 36GB+ doesn't change the fact that 4 18GB drives in a stripe set are faster than 1 72GB drive though. One must consider the availability of the parts though, so perhaps 32x36GB drives would be a good way to balance performance and storage cost. === Andy Webb[EMAIL PROTECTED] www.swinc.com Simpler-Webb, Inc.
