Additionally, the replicated server at the NOC implements high availability, acting normally as a standby server but ready to provide service in the event of a hardware or other failure at the remote office. Failover, if required, is automatic, and takes less than a minute. Once failover occurs, Outlook automatically reconnects to the NOC server without needing to be restarted.

Replication and high availability are implemented using standard, supported Linux components: specifically, DRBD and Linux-HA-heartbeat. No special tools or hardware are required, making high-availability for the geographically remote office practical and cost-effective for the first time.

The PostPath Server Remote Office Edition’s on-site server deployment minimizes bandwidth requirements by eliminating WAN usage when local users access their data. This eliminates both duplicate WAN downloads and WAN traversal of local emails. Traffic management is also supported and removes the risk of choking low bandwidth connections during peak times.

For any IT professional that has suffered the headaches of trying to deploy and manage Exchange servers for their remote offices, PostPath Remote Office Edition provides relief by including native support for Outlook, Blackberry, Active Directory, and other Exchange Servers, with the ability to deliver low latency, minimized hardware cost, offsite replication and high availability (HA), and low maintenance over low-bandwidth pipes.
