Re: P4300 SAN Starter DR Question
Yes you can pull those 2 boxes apart. Network RAID will make that all data blocks will be spread accross the 2 sites.
However there are some drawbacks.
HP suggests to have at least 2 boxes per site which means that you would need 2 starter kits...
You also have to think about split-brain situations on network level where the implelemtation of the so called FailOver Manager FOM is required.
I have done 10's of installations like this and have great experiences with it but you need to know what you are doing...

Re: P4300 SAN Starter DR Question
The best would be that it is fast enough to do synchronous replication. Then you can move VM's with a regular vMotion...
If the bandwidth is not sufficient, you will have to use Remote Snapshot technology...
I do not have practical experience yet with snapshotting VMFS volumes, but I read in other forum topics that it should be working...

Re: P4300 SAN Starter DR Question
Could we move the VMs with Vmotion and run off of the off-site server and SAN?

Re: P4300 SAN Starter DR Question
Otherwise you will need to use remote snapshots so make a snapshot on 1 side and replicate it to the other site towards a remote volume.
At the other site you can make a remote volume back a primary volume and do the test with an ESX server over there to mount the volume and import a VM on it... Should work... But like I said personaly not tested yet...

Re: P4300 SAN Starter DR Question
Would it be possible to just point the main host to the backup SAN or is the speed not enough?
Thanks again.

Re: P4300 SAN Starter DR Question
The snapshot I mean is on VMFS SAN volume level and replicate that to the other side.
P4000 (Lefthand) sees volumes, not the data (the VM's) on it...
