Re: How to verify/fix High Disk Read Latencies in Exch2003 ?

Darn. I think this is an actual issue.
I am running Perfmon Physical Disk/% DiskTime:
The paritition in which the information store is mounted shows %DiskTime
utilization of 80-100 steady. I will run the Troubleshooting Analyzer to see
what I get.

The servers have the databases installed on a SAN drive, Raid 1+0, with
143GB free disk space (70% free disk space). Not sure what could be causing
such latency...
