Does it have to deploy 2 vCenter when we use ASM/VM for replication?
Hi,
We want to deploy 2 EQL for my VM Infrastructure. 2 EQL will be setup as 2 storage group in the same IP SAN, 1 for production and 1 for backup. We will replicate production data to backup storage. We only have 1 vCenter. Can we install ASM/VM on single vCenter to control the data integrity when the replication is scheduled? Thanks!

From the installation guide;-
Requirements for Replication Partners
If a replication partner is configured (that is, there are two EqualLogicHost Integration Tools for
VMware appliances) each needs to be upgraded or restored individually. They should be
upgraded or restored from databases at around the same time to avoid any inconsistencies
between them. You must also use the plug-in GUI to set the replication partner on both sides
after the upgrade.
You need second one in case you want to replicate the other way

Yes, you can do it with just one vCenter. ASM/VE just needs access to the VCS and the sending array. The volume you want to replicate must already be configured for replication. So ASM/VE job is to connect to the VCS, ask it to create VMware snapshots, when done, ASM/VE connects to the array and initiates a replication of that volume or volumes. Then connects back to VCS to delete/merge the VMware snapshots.
