Hoping someone can give some advice.
Im setting up SRM with vSphere replication. The storage layout is at a simple level :
Protected site
1 x vCenter managing
2 x ESXi Hosts in subnetA with its own datastores presented (2 x datatores 500GB each)
5 x VMs of 50GB each
2 x ESXi Hosts in subnetB with its own datastores presented (2 x datasores 500GB each)
5 x VM's of 50GB each
In additon to this there are also the SRM, VRS and VRM servers at both sites for vSphere replication.
The hosts in subnet A and B cannot see each others datastores. This is done by zoning on the fabric.
Recovery Site
Same as protected site but with ony 1 ESXi host in each of the subnets and 1 x datastore for each subnet at 500GB.
A subset of servers hosted in both subnets have been selected for protection.
My question is around storage. When an SRM test is run I understand that a snapshot of the LUN is made. So I want to run an SRM test on a VM located in subnet A. Do I have to provide another 500GB LUN just for SRM testing for the snapshot to go into ? or is it a smaller LUN I need to make available ?
Any documentation on what happens at a storage level on an SRM test with vsphere replication would be appreciated.
Thanks
