Source and Target Sites
In a typical vSphere Replication installation, the source site provides business-critical datacenter services.
The target site is an alternative facility to which you can migrate these services.
The source site can be any site where vCenter Server supports a critical business need. The target site
can be in another location, or in the same room to establish redundancy. The target site is usually located
in a facility that is unlikely to be affected by environmental, infrastructure, or other disturbances that might
affect the source site.
vSphere Replication has the following requirements for the vSphere
®
configurations at each site:
n
Each site must have at least one datacenter.
n
The target site must have hardware, network, and storage resources that can support the same
virtual machines and workloads as the source site.
n
The sites must be connected by a reliable IP network.
n
The target site must have access to networks (public and private) comparable to those on the source
site, although not necessarily the same range of network addresses.
Connecting Source and Target Sites
Before you replicate virtual machines between two sites, you must connect the sites. If the sites use
different SSO, you must provide authentication details for the target site, including IP or FQDN , user and
password information. When connecting sites, users at both sites must have VRM remote.Manage VRM
privilege. When you connect sites that are part of the same SSO, you need to select the target site only
without providing authentication details, as you are already logged in. After connecting the sites, you can
monitor the connectivity state between them at Target Sites tab.
How vSphere Replication Works
With vSphere Replication, you can configure replication of a virtual machine from a source site to a target
site, monitor and manage the status of the replication, and recover the virtual machine at the target site.
When you configure a virtual machine for replication, the vSphere Replication agent sends changed
blocks in the virtual machine disks from the source site to the target site, where they are applied to the
copy of the virtual machine. This process occurs independently of the storage layer. vSphere Replication
performs an initial full synchronization of the source virtual machine and its replica copy. You can use
replication seeds to reduce the amount of time and bandwidth required for the initial replication.
During replication configuration, you can set a recovery point objective (RPO) and enable retention of
instances from multiple points in time (MPIT).
