disk performance issues
Posted on 2010-08-30
IBM 3650 M3
RAID 10 using m5015 with BBU (Write Cache Enabled)
-all drives are used in the RAID 10 Array
16 x 146gb 10k rpm sas drives
stripe size 1mb
dual qc xeon
Function: VMWARE esxi 4.x Server, running 3-4 vm.
There will be an oracle db server, and app server, and windows server 2003
Problem: Disk Performance. Currently when copying a 3gb USR folder on the same disk & vm it takes over 3 minutes to copy.
I was thinking part of the problem is the disk stripe size i chose in the RAID setup? Is there a recommendation of a stripe size for this config above? The server is not in production yet, waiting to solve the disk performance issue.
