adaptec scsi performance monitor utility ? - is there one ?

[troyquigley]

i thought my 2 servers were having nic problems or some type of network problems. after all the settings and all the checking, it seems it may actually be my scsi is overloaded.

i am looking for a utility that will tell me how hard my adaptec 2120s scsi raid controller is getting hit.

What OS? Assuming windows...


For starters, just fire up perfmon and add disk queue length. Should be no more than 2 items queued *per spindle*.

Run diskperf -y and reboot to get the diskperf filter driver loaded if you get zeros in your performance data.

cool.

Fire up perfmon and have a look at your disk queue length. It will give you a very good indication if your mass storage is bottlenecking.

Have it log for a few hours during your peak load times.
