Slow disk performance DL380
And experiencing very slow disk performance.
A file copy of 8 MB within the array takes about 1 minute.
Nothing to see in logfiles.

Re: Slow disk performance DL380
and the latest version FW2.56(+) and driver
Strange is that on a earlier 380 (with 4 38,6 in a 0/1 conf) there is much better performance.

Re: Slow disk performance DL380
There's not much settings that can be done on the hardware raid that affect performance ( beside RAID level ).

Re: Slow disk performance DL380
Do you you have more RAIDs with de same problem?
Does your server works fine?
Has these disks the same fw, p/n, blocks?

Re: Slow disk performance DL380
You will want to change that to 50/50, or 25/75.
Also, check your array rebuild priority, etc. If the array is still mirroring, and rebuild priority is set to "high", rebuild IOs will take priority over data writes.
