Keeping exact copy of data from one EVA6000 to another EVA6000

[Creating boot LUNs on S]

Hi,

I have a two node cluster setup.
These nodes are connected to two EVA6000, wherein the other EVA6000 would be an exact replica of the other and would work as a failover in case one EVA6000 fails.

What kind of technology would I have to implement in order to keep this exact replica?
Do I have to implement software mirroring?
If I have to implement software mirroring how can I do it?

Regards,
Naveen

I think, Continuous Access is the best solution for you (array controller based):

You can also use host base replication, like Veritas Volume Replicator

You can also try HP OV Storage Mirroring...

OVSM is a product from NSI called Double Take. It is software/host based replication. Aside from replicating the data from one host to one (or maybe more) target(s), it can also "failover" services from the host to the target. The target effectively takes over the Name and IP configuration of the regular host in the case of a host failure.

Hi Naveen,
IMHO the best solution would be combination Continuous Access EVA with Cluster Extension EVA.
This solution allow you separate yours cluster nodes to differen locations.

Of course this solution is applicable only for MS cluster.
