DUAL EVA REPLICATION AND SERVICE GUARD

[wayne_104]

Hi

I have a question
The client has 2 eva they want to have the cluster address both eva and replicate the data between the EVA. such that if an eva goes down they can continue working.

If one of the nodes goes down they will continue working.

I was thinking of two possibe solutions.

easiest. present disks from both eva's and mirror them so that when they write it is written at same time.

or to use clx solution which will cost big money.

Is there any other way that I should be considering?

You've covered the main two options:

- Host based mirroring in a Serviceguard Stretch Cluster
- Array based replication in a Serviceguard Metrocluster (the CLX option is actually for non-Serviceguard clusters - like MSCS on Windows)

The only other thing I would consider would be application-based replication - for example if all the data for the application were in an Oracle database you could consider using Oracle Dataguard.
