SRM Install with Multiple VCs at Site

Question on SRM (5.1) install with multiple vCenters at site. I cant find a clear answer on this.  This is a classic Protected/Recovery DR design.  Two datacenters, Prime and "DR".  Question has to do with number of VC at the Prime Site. I have plenty of information on SRM datacenter locations with one vCenter each, but not multiple.

The Prime Datacenter has multiple vCenters representing different environments.  For SRM the two sites will match.  For every VC at PRIME, there will be one at DR.  However is on SRM that I have the issue:

  • Do I need to install SRM Instance for each VC at Prime location and its partner at DR location? Would this also mean each SRM instance needs its own DB?

OR

  • Can I install a single instance of SRM on its own server at each site to control the Prime site and all VCs located there and have the same at the DR site?  This would be very similar to SSO in that respect (one SSO server per location).

Consolidating the VC is not an option.  Company likes their environments to be separated even on the vCenter level.  One upside, all the VCs are linked.  Very nice single pane of glass way to review the all the VCs in the corporation.

Thanks,

It's one VC per SRM and one SRM per VC, each with their own DB, so unfortunately you'd need a whole lot of VCs, SRMs, and DB instances for this situation.

Each site could have a single SSO instance to authenticate all of these environments, but if they can't consolidate VC management then they're pretty much stuck.

UNLESS.... they want to do a shared recovery model.  In that case they could identify one of the SRM/VC pairs as the 'primary failover target' and have all the remote VC/SRM instances fail over to that one.  But they're not saving on VC/SRM/DB instances really as each Source environment would still need a dedicated VC and thereby a dedicated SRM to pair with.

Ken,

Thanks for responding, I was really hoping you would.

So I am crystal clear here.  Every VC needs its own SRM Instance.  I have two vcenters at the primary/protect site, I need two SRM Instances/Servers correct? And of course the duplication on the other side at the DR Site.

Thanks,
