The environment in which you run the vSphere Replication virtual appliance must meet certain hardware requirements.
vSphere Replication is distributed as a 64-bit virtual appliance packaged in the .ovf format. It is configured to use a dual core CPU, a 16 GB and a 2 GB hard disk, and 4 GB of RAM. Additional vSphere Replication servers require 716 MB of RAM.
You must deploy the virtual appliance in a vCenter Server environment by using the OVF deployment wizard on an ESXi host.
vSphere Replication consumes negligible CPU and memory on the source host ESXi and on the guest OS of the replicated virtual machine.
vSphere Replication can be deployed with either IPv4 or IPv6 address. Mixing IP addresses, for example having a single appliance with an IPv4 and an IPv6 address, is not supported. To register as an extension,
vSphere Replication relies on the
VirtualCenter.FQDN property of the
vCenter Server. When an IPv6 address is used for
vSphere Replication, the
VirtualCenter.FQDN property must be set to a fully qualified domain name that can be resolved to an IPv6 address or to a literal address. When operating with an IPv6 address,
vSphere Replication requires that all components in the environment, such as
vCenter Server and
ESXi hosts are accessible using the IPv6 address.
