In my last post, I walked through configuring ActiveCluster and your VMware environment to prepare for use in Site Recovery Manager.
Site Recovery Manager and ActiveCluster Part I: Pre-SRM Configuration
In this post, I will walk through configuring Site Recovery Manager itself. There are a few pre-requisites at this point:
- Everything that was done in part 1.
- Site Recovery Manager installed and paired
- Inventory mappings in SRM are complete (network, folders, clusters, resource pools etc).
- Downloaded and installed the FlashArray SRA 3.x or later on both SRM servers.

About four years ago, we (Pure Storage) released support for our asynchronous replication and Site Recovery Manager by releasing our storage replication adapter. In late 2017, we released our support for active-active synchronous replication called ActiveCluster.
Until SRM 6.1, SRM only supported active-passive replication, so a test failover or a failover would take a copy of the source VMFS (or RDM) on the target array and present it, rescan the ESXi environment, resignature the datastore(s) then register and power-on the VMs in accordance to the SRM recovery plan.
The downside to this of course is that the failover is disruptive–even if there was not actually a disaster that was the impetus for the failover. But this is the nature of active-passive replication.
In SRM 6.1, SRM introduced support for active-active replication. And because this type of replication is fundamentally different–SRM also changed how it behaved to take advantage of what active-active replication offers.
