Details
Array-based On-Premises:
Storage Replication Adapter (SRA) software specific to each storage array that is used with SRM must be installed on the SRM host at both the protected site and the recovery site. SRM supports the use of multiple SRAs. However, virtual disks from a single VM cannot be spanned across multiple storage arrays from different manufacturers.
vSAN does not require a Storage Replication Adapter (SRA) to work with Site Recovery Manager (SRM).
VR On-Premises/Public Cloud:
vSphere Replication (VR) requires 1 Appliance (VRAp) to be deployed at both the source and target sites for management and coordination.
VR also requires an Agent (VRAg) as well as a vSCSI Filter driver to be deployed on each physical server that is part of a cluster hosting protected VMs (source site). The filter driver is used for tapping into the VMs Input/Output (IO) stream.
VR also requires one or more Replication Servers (VRR) to be deployed on the target site for processing and storing the incoming replication data. The vSphere Replication Appliance (VRAp) at the target site had a VRR embedded.
