Installing SRM to Use with a Shared
Recovery Site 11
With SRM, you can connect multiple protected sites to a single recovery site. The virtual machines on the
protected sites all recover to the same recovery site. This configuration is known as a shared recovery site, a
many-to-one, or an N:1 configuration.
In the standard one-to-one SRM configuration, you use SRM to protect a specific instance of vCenter Server
by pairing it with another vCenter Server instance. The first vCenter Server instance, the protected site,
recovers virtual machines to the second vCenter Server instance, the recovery site.
Another example is to have multiple protected sites that you configure to recover to a single, shared
recovery site. For example, an organization can provide a single recovery site with which multiple protected
sites for remote field offices can connect. Another example for a shared recovery site is for a service provider
that offers business continuity services to multiple customers.
In a shared recovery site configuration, you install one SRM Server instance on each protected site. On the
recovery site, you install multiple SRM Server instances to pair with each SRM Server instance on the
protected sites. All of the SRM Server instances on the shared recovery site connect to the same
vCenter Server instance. You can consider the owner of an SRM Server pair to be a customer of the shared
recovery site.
You can use either array-based replication or vSphere Replication or a combination of both when you
configure SRM Server to use a shared recovery site.
Example: Using SRM with Multiple Protected Sites and a Shared
Recovery Site
An organization has two field offices and a head office. Each of the field offices is a protected site. The head
office acts as the recovery site for both of the field offices. Each field office has an SRM Server instance and a
vCenter Server instance. The head office has two SRM Server instances, each of which is paired with an
SRM Server in one of the field offices. Both of the SRM Server instances at the head office extend a single
vCenter Server instance.
