Using vSphere Replication with SRM on page 13
SRM can use vSphere Replication to replicate data to servers at the recovery site.
n
Using Array-Based Replication and vSphere Replication with SRM on page 17
You can use a combination of array-based replication and vSphere Replication in your SRM
deployment.
n
SRM and vCenter Server on page 18
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.
About Protected Sites and Recovery Sites
In a typical SRM installation, the protected site provides business-critical datacenter services. The recovery
site is an alternative facility to which SRM can migrate these services.
The protected site can be any site where vCenter Server supports a critical business need. The recovery site
can be located thousands of miles away from the protected site. Conversely, the recovery site can be in the
same room as a way of establishing redundancy. The recovery site is usually located in a facility that is
unlikely to be affected by environmental, infrastructure, or other disturbances that affect the protected site.
The vSphere configurations at each site must meet requirements for SRM.
n
Each site must have at least one datacenter.
n
If you are using array-based replication, identical replication technologies must be available at both
sites and the sites must be paired.
n
The recovery site must have hardware, network, and storage resources that can support the same
virtual machines and workloads as the protected site. You can oversubscribe the recovery site by
running additional virtual machines there that are not protected. In this case, during a recovery you
must suspend non-critical virtual machines on the recovery site.
n
The sites must be connected by a reliable IP network. If you are using array-based replication, ensure
that your network connectivity meets the arrays' network requirements.
n
The recovery site should have access to comparable public and private networks as the protected site,
although not necessarily the same range of network addresses.
Pairing the Protected and Recovery Sites
You must pair the protected and recovery sites before you can use SRM.
SRM includes a wizard that guides you through the site-pairing process. You must establish a connection
between the sites and you must provide authentication information for the two sites so that they can
exchange information. Site pairing requires vSphere administrative privileges at both sites. To begin the site-
pairing process, you must know the user name and password of a vSphere administrator at each site. If you
are using vSphere Replication, you must pair the vSphere Replication appliances.
