Good failover plan for fax server

By yengchew ·
We are migrating our fax machines to fax servers called Rightfax. We will install 4 fax cards and 4 channels to replace 4 fax machines. We need to ensure that a good failover system is in place so that the public can communicate to our organisation via fax at all times. What failover must be put in place ?

Good failover plan for fax server

by MikeTalonNYC In reply to Good failover plan for fa ...


As I've discussed in many of my Disaster Recovery Techmails, a solid real-time data replication and failover technology will be able to provide you with the type of protection you require here.

In your case, since the fax systems are host-based, I'd probably suggest a software-based replciation system (there are several on the market) that allows for real-time byte-level data transfer between a primary and secondary server. The secondary server would be configured with the same hardware and applications as the primary, allowing it to stand in at any time with no notice if neccessary. The replication systems keep the data intact on both machines and allow for the identity of the primary to be moved to the secondary during failover, without the need to cluster the two boxes.

Since I am a columnist, I can't mention specific products, however a Yahoo search for "real-time byte-level replication" will yeild results on a few different products you may wish to investigate.

Hope this helps.
