Hello,
A while ago were decided to use SRM for our disaster recovery tool for about 25 vms. We use a mix of vSphere Replication and Array base replication (Currently using Asyncronous IP replication with a storwize v5000 and an older v7000). It's been working well for us but the topic of stretched cluster keeps coming back in our internal discussions mostly to be able to balance workload from our main site to our recovery site. After upgrading everything to version 6, I am now able to move VMs from one vCenter to another but I have to move storage also... It works well, but the it would be great if we could simply use a standard vMotion and use the replicated storage instead.
We've recently acquired 2 new v7000 with hyperswap which offers syncronous replication. I was told by IBM that in order to move workloads between our 2 sites, I have to eliminate one vCenter thus get rid of SRM. This redbook also suggest a one vCenter topology.
From what I read in this SRM Whitepaper for version 6.1, I can have best of both worlds by configuring SRM with stretched storage.
I was wondering if some of you have configured SRM with stretched storage. I'm curious to know how I could present the same volume to 2 vCenters.
Thank you!
