Babette,
some of my customers with SANs are far below that: from 2 to 5ms (normal
load).
Thanks!

Hey! I would be happy if I could get such good numbers. I frequently have average wait time for I/O up in the 100-200ms range!!

Carmen,
I know one unhappy customer with NetApp. This customer is using Baan.=20
The average wait time for I/O is:
db file sequential read 13.7ms db file scattered read 17.9ms
The response time in average consists of: 15% of service time and 85% of
wait time due to slow I/O. They complain that the average CPU load is =
only
15-20%. They have also problem with unhappy final users. The supplier =
tried
to improve the performance but with no major change. If somebody would =
ask
me for the advice about NetApp I wouldn't recommend it.

I am experimenting with creating tablespaces/datafiles on a new NetApp filer we got installed.
The sysadmin configured a dedicated volume out the the 9tb behemoth with a stripe size of 128k, which he tells me is what tech support told him to.
Anybody on the list with a NetApp storage device with Oracle on it? How did you configure it? Wha kind of performance do you get? Any caveats?
Thanks,
Carmen Rusu
