2x MSA 2000 storages for a cluster failover
We have 2 storages the MSA2000 iSCSI series. We need to replicate the volumes somehow between them to provide a failover solution. We have a volume with one LUN and the second volume with a different LUN on the second storage. As far as I can see the torage itself doesn't provide any sort of floating LUN for failover so not sure how to implement this. One storage is in one DC and the second one sits in different DC. The question is , is this at all possible and if so did anyone attempt to implement such thing?

Re: 2x MSA 2000 storages for a cluster failover
the MSA2000 G1 and G2 can't replicate/ mirror data, but the P2000 G3 can do this. With the G3 you can do remote snapshots. That's not a synchronuos mirror, but very useful to bring data to a second site.
In you case a host-based mirror can be a solution. Just present volumes from both MSAs to a host and create a mirror. If one site fails, the data will be still available.

Re: 2x MSA 2000 storages for a cluster failover
we are in implementation phase with streched domain HP SVSP project.
Use this or other Storage virtualization systems... (FalconStor, DataCore...)
