Excellent inputs. Thanks to all of you !!
ASM might not be a best option for me by considering a two node cluster
w/ very large amounts of data getting mirrored across two storage
arrays. So my other option would be GPFS. Are there any /similar//other
concerns with GPFS in the same architecture ?
regards,
Madhu

Replication via Oracle Data Guard or third party tools is a much
better option. Just storing backups remotely is a much more reliable
alternative than distance storage box with ASM.

1- you can use ASM to mirror your data on the remote site, mainly by
using a
'failover' disk group. It's very easy to setup.
