Configure Array-Based Replication
To protect virtual machines that you replicate by using array-based replication, including virtual machines
that you protect by using storage policy protection groups, you must configure storage replication adapters
(SRAs) at each site.
Install Storage Replication Adapters
If you protect virtual machines by using array-based replication or by using array-based replication with
storage policy protection, you must install a Storage Replication Adapter (SRA) specific to each storage
array that you use with Site Recovery Manager. An SRA is a program that an array vendor provides that
enables Site Recovery Manager to work with a specific kind of array.
You must install an appropriate SRA on the Site Recovery Manager Server hosts at the protected and
recovery sites. If you use more than one type of storage array, you must install the SRA for each type of
array on both of the Site Recovery Manager Server hosts.
NOTE You can configure Site Recovery Manager to use more than one type of storage array, but you cannot
store the virtual machine disks for a single virtual machine on multiple arrays from different vendors. You
must store all of the disks for a virtual machine on the same array.
Storage replication adapters come with their own installation instructions. You must install the version of an
SRA that corresponds to a specific Site Recovery Manager version. Install the same version of the SRA at
both sites. Do not mix SRA versions.
If you are using vSphere Replication, you do not require an SRA.

Check the availability of an SRA for your type of storage by consulting the VMware Compatibility Guide
