SSD with GPFS ?

Hi,

does anyone here happen to know if I could run GLVM or GPFS on Solid State Disks?

I have a high volume / high transaction Sybase HACMP cluster currently setup with SRDF to the DR datacentre. My business now considers to move everything to SSD storage but we still need to get the data to the DR side - and replication server is not an option - and they want to keep the cluster.
So I have to come up with some geographical replicated cluster solution on disk basis - I was thinking about a geographical cluster but they reject as that means if anything happens to the cluster it would impact both sides - they want something independant so a single box or a cluster on the DR side but still real time / close to real time data.

I am open for any ideas

Regards
Nicki
