Hello All,
I'd like to have some feedback on what we are trying to achieve here...
On the same site, we have 2 distant rooms for disaster recovery on the same site. ESX host(s) in each room with its own SAN. We would like to have the best possible solution for an Oracle Database with transparent failover and thus (perfect / live) replication between those two rooms.
Our current idea would be to use RAC and ASM - with an ASM Disk Group that has disks from the SAN in each room. The idea is to avoid using any kind of SAN replication and let Oracle handle everything. I would then configure the Oracle Virtual Servers in room #1 and #2 with disks from the SAN in room #1 and from the SAN in room #2. All of them in the same ASM disk group.
The way I understand this, Oracle ASM will handle the "replication" and if Room #1 burns down, RAC will allow business to continue transparently.
Am I day dreaming?
What about having disks from two SAN in different rooms in an ASM disk group? Is this viable?
Any other ideas / possibilities to solve our issue?
Thank you very much!
X.
