I have a question to hopefully clarify something for me.

The offsite DBA has told us that our database is on a server wish "racks of
drives" and mentioned a number of about 20 drives at one time.

Yet, when I look on Enterprise Manager all I can find is 5 drives listed
(C,D,E,F,G).

We are not using ASM.

Would Oracle Enterprise Manager group disks into a single entity or does it
show what is actually there?
Or could there be another explanation?

Thanks.

The drives could be protected by RAID. For example the "C" logical volume in
Windows could correspond with 2 "physical" hard disks with RAID-1 protection
(mirroring). Your local system administrator probably has more info :-)

Physical drives, from your standpoint, are irrelevant. You are looking
at logical volumes.

Thanks for the clarification.

That brings up another question. If our system is constantly experiencing
I/O throughput problems on drive (or volume) G: and the disk utilization for
same drive/volume has been near or at 100% for the past week would that
indicate that the volume needs to be split into more volumes or the database
files spread across more disks than they aready are?
