Deployment Planning for Citrix Xen

Deployment for the Virtual Server Agent (VSA) for Citrix Xen can include the following components:

  • The Virtual Server Agent can be deployed on a dedicated virtual machine that resides on a standalone XenServer or on any XenServer in a Xen pool. The virtual machine with VSA installed acts as a VSA proxy to provide backup and recovery services for a Xen pool. Multiple VSA proxies can provide load distribution and load balancing within a Xen pool to improve performance.

    Any VSA proxy in a Xen pool can provide data protection services for VMs residing on a shared storage repository (datastore) for the Xen pool; any VMs on local storage must be served by a proxy that has access to the local storage.

    The VSA proxy is managed by an existing CommServe system and communicates with the CommServe system and with MediaAgents in the network.

  • MediaAgents can be deployed on physical machines or virtual machines to manage the transmission of data between clients and backup media.
