CSM - Bridged Mode - Routed Mode Question

[astanislaus]

Customer's request involves setting up a backup (failover) BCR server to receive hand held device scan events.

The following needs to be performed:

- Build new server up as identical to AAEPRDBCR01 (named AAEPRDBCR02).

- Application to be installed onto the new server (configured identically to AAEPRDBCR01)

- Configure customer's CSM to parse requests to AAEPRDBCR01, and failover to AAEPRDBCR02. i.e. when BCR01 is unplugged the CSM should realise and begin parsing requests through BCR02. If BCR01 comes online again, the requests should once again fall back to BCR01.

I was thinking that the two servers would reside on eg.....VLAN 13 'BiscomBCR' and Users access these servers.

Does it need to be routed or can we do the same config in Bridged mode, where the servers have the same IP addressing?

Any pointers to any useful links is much appreciated.

You can do this in bridged mode. You can basically create a backup serverfarm which contains your new server. (CR02). It will only be used if the normal serverfarm containing your existing server (CR01) is unavailable.

Attached is a link to the CSM config doc - have a look at the config examples for the backup server farm. (Make sure you read the caveats about stickiness to understand what happens when the primary serverfarm comes back on line).

Hope this helps
