Business Continuity and Disaster Recovery

A Parallels RAS farm placement depends on the location of a back-end resource. Therefore, it is possible to continue operations by adding an additional remote location where the back-end resources are replicated (the appropriate software and hardware solutions are out of the scope of this document) and placing one more Parallels RAS site in this location.

Setting up a disaster recovery site, and then configuring the Parallels Client to use the closest site as the primary connection and the disaster recovery site as the secondary connection, allows users to always be connected to the primary site and to continue working using the disaster recovery site in case of failure.

WAN users can be invited to use all sites and setup HALB VS IP address of the first site as Server Address and HALB VS IP address of the second and third sites as Secondary Server IP in the RAS connection settings on the Parallels Client side. The RAS connection settings can be configured either centrally (via Client Policy in the Parallels RAS Console) or manually.

Installation Notes

Primary RAS Connection Broker is installed using the Parallels RAS installer (standard installation). Secondary RAS Connection Broker is push-installed from the RAS Console.

HALB is installed as a ready-to-use virtual appliance and configured in HALB VS properties.

All other components are push-installed from the RAS console.
