I would look at network on the media server, network on the clients,
client power, and scsi bus configs of the drives.

Subject: [Veritas-bu] drive metrics

I am trying to get performance metrics. I have 10 dlt7000 drives in an
L700
on 3 Crossroads bridges connected to 
an E4500 with 3 JNI 1 Gb HBAs.

I am graphing the drives in Cricket calling a script with iostat -Mcxnt.
My performance seems to avarage around 3 M/per second.

Does anyone have any suggestions for performance improvement and or
tools to
drill down further to find the bottleneck?
