DL320s and P800 poor performance

[eltorito]

Dear Gurus,

I have a NAS DL320s and a P800, before I had installed a Smart Array P400 and the performance on Raid 5, Raid 1 was ok. We attached an eclosure five days ago, and changed the Smart Array P400 to P800.
Now we have poor performance when write to HardDisk (so poor performance).

What parameters I need to check?
I was trying to enable cache write (by OS or ACU line) but I could not do it.

If someone can help me.

Thanks

Hi,

Have you installed the BBWC option ?
You need that to enable the write cache.

Cheers,

Rob

I dont know if the dl320s has installed the BBWC.

HP installed the new Smart Array P800.

Is there a command to verify this?

Thanks!
