VRA Installation Requirements

To install a VRA you require the following on the host:

■ (vSphere only) The ESX/ESXi version must be in accordance with supported ESX/ESXi versions in the Interoperability Matrix, and Ports 22 and 443 must be enabled on the host during the installation.

Install-WindowsFeature –Name Hyper-V -IncludeManagementTools -Restart

You must know the following information to install a VRA:

■ (vSphere only) If the ESXi version is 5.5 or higher and the VRA should connect to the host with user credentials, or if the ESXi version is lower than 5.5 (4.x or 5.x), the password to access the host root account.

Note: For ESXi versions 5.5 or higher, by default the VRA connects to the host with a vSphere Installation Bundle, VIB. Therefore, it is not necessary to enter the password used to access the host root account.

■ The storage the VRA will use, and the local network used by the host.

■ The network settings to access the peer site; either the default gateway or the IP address, subnet mask, and gateway.

Note: When the gateway is not required, you can specify 0.0.0.0 as the gateway, for example when performing self replication.

■ If a static IP is used, instead of DHCP, which is the Zerto recommendation, you need to know the IP address, subnet mask, and default gateway to be used by the VRA.

Note: In a non-production environment it is often convenient to use DHCP to allocate an IP to the VRA. In a production environment this is not recommended. For example, if the DHCP server changes the IP allocation on a reboot, the VRA does not handle the change.

■ If the peer site VRAs are not on the default gateway, you must set up routing to enable the VRAs on this site to communicate with the peer site VRAs before defining the VRAs.

■ Setting up routing after defining VRAs only applies to VRAs installed after the routing is set.

■ Any existing VRA is not affected and access to these VRAs continues via the default gateway.

■ If the default gateway stops being used, you must reinstall the VRAs that were installed before setting up paired site routing.

■ (vSphere only) For the duration of the installation of the VRA, the Zerto Virtual Manager enables SSH in the vCenter Server.

■ (vSphere only) You must know the following information to install a VRA:

■ The password to access the host root account, for ESXi 4.x and 5.x.

■ The datastore the VRA will use and the local network used by the host.

■ The network settings to access the peer site; either the default gateway or the IP address, subnet mask, and gateway.

■ If a static IP is used, instead of DHCP, which is the Zerto recommendation, you need to know the IP address, subnet mask, and default gateway to be used by the VRA.
