Carmen,
I know one unhappy customer with NetApp. This customer is using Baan.
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.
Joze

Subject: db datafiles on NetApp FAS940 filer
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
