Home -> Community -> Mailing Lists -> Oracle-L -> RE: SAN and ORACLE
Ed - I'm not a SAN expert. But the one thing that we are working on/striving
for with the DB's here are two file systems presented to the Host.
We'll use one *mount pointA* for the use of Data Files, a copy of the
control files, online redo logs... and we will use *mount pointB* for the
Oracle binaries, copy of control files, copy of online redo logs, archived
redo logs. And in some cases there is a copy of the backup files on this
mount point as well as on tape
Now for the makeup of the LUNS.... In some cases, the storage guys have the File systems makeup separated on different frames. Where Frame1 would contain *mount pointA*, and Frame2 would contain *mount pointB*.
And then we would have the mirror(M1, BCV) for each file system allocated
vice versa...
Confused yet? I am.. It's gotta be 5:00 somewhere - beers on me.

Subject: SAN and ORACLE
Hi,
I'm interested in people's experiences with SAN, specifically SHARK, and Oracle.
I have adopted a system where all of the Oracle files, including archive, redo, rbs etc, reside on the same "logical" device. I know that the placement of this data is handled by the SAN.
My concern is with the recovery issue, more than with performance. I would like to separate the data from the Oracle files that are required for recovery (archive,redo,rbs,etc). I was hoping to create a separate "logical" device which has it's own physical devices that are separate from the data, and place the recovery files there.
I was told that this is not possible with a SAN. Is this really the case ? thanks for your input.
