How many RP clusters can be managed within a single Virtual Center/SRM Context?

How many RP clusters can be managed within a single Virtual Center/SRM Context?

I have a client that has four replication pairs of RP clusters.  They'd like to manage/control SRM failover between the failover pairs within a single Virtual Center/SRM context.

Is this possible?

If not, is there an upper limit of pairs?

Is this documented anywhere?  I searched EMC Support and VMware support, with no luck.

Thanks,

Eric
