Configuring Master and Replica for Full System Scenarios

Full system scenarios require three hosts instead of two, typical for other CA ARCserve RHA scenarios:

• Master server - is the host that you want to protect. This host can be physical or virtual.
• Appliance - is a VM where you installed the CA ARCserve RHA Engine.
• Virtual Platform Host - is the server where the Appliance VM is running.

To configure the Master server

For Full System scenarios, the Master can be any Windows machine, physical or virtual, supported as both a guest OS in the virtual environment and by the CA ARCserve RHA Engine. For a complete list of supported operating systems, see the CA ARCserve RHA Release Notes.

To configure the Appliance

Configure a virtual machine as follows:

• For Xen platforms, install XenServer Tools on the Appliance VM.

  Note: If your virtual platform is Citrix Xen 6.0, install the .NET 4.0 Framework on the protected master. The .NET 4.0 Framework is required for installing the Xen tool on the virtual machine that the appliance created.

• For ESX and vCenter platforms, install VMware Tools on the Appliance VM.
• Install the CA ARCserve RHA Engine on the Appliance VM.
• For Amazon EC2, ensure that the date and time are correct and synchronized to your system and the network can access AWS.

The Appliance VM acts as the Replica in Full System scenarios. Data is replicated to a VHD stored in the appliance. If a failover is triggered, a new VM is created and the VHD containing replicated Master data is attached to this new VM.

Important! Do not manually delete the virtual machine, its configuration, and virtual disk files, otherwise, the scenario can fail.
