SRM and vCenter Server
SRM Server operates as an extension to the vCenter Server at a site. Because the SRM Server depends on
vCenter Server for some services, you must install and configure vCenter Server at a site before you install
SRM.
SRM takes advantage of vCenter Server services, such as storage management, authentication,
authorization, and guest customization. SRM also uses the standard set of vSphere administrative tools to
manage these services.
You can use SRM and vSphere Replication with the vCenter Server Appliance or with a standard
vCenter Server installation. You can have vCenter Server Appliance on one site and a standard
vCenter Server installation on the other.
How Changes to vCenter Server Inventory Affect SRM
Because SRM protection groups apply to a subset of the vCenter Server inventory, changes to the protected
inventory made by vCenter Server administrators and users can affect the integrity of SRM protection and
recovery. SRM depends on the availability of certain objects, such as virtual machines, folders, resource
pools, and networks, in the vCenter Server inventory at the protected and recovery sites. Deletion of
resources such as folders or networks that are referenced by recovery plans can invalidate the plan.
Renaming or relocating objects in the vCenter Server inventory does not affect SRM, unless it causes
resources to become inaccessible during test or recovery.
SRM can tolerate certain changes at the protected site without disruption.
