backup server on an ACE

[axfalk]

When creating a backup server on an ACE running A5(2.1), we're using the probe as the trigger. Once the primary real server has failed to the backup,  will it fail back to the primary server when the probe deems the primary server available?

It's just  as well as the ACE manual documents the backup serverfarm, there's dearth of info on the backup server.

Thanks.

Hi Greg,

Backup rserver as you know would be configured with standby keyword. When primary server will be Operational (probe passed)

- Existing connections on backup keep accessing backup.

- For new connection requests ACE looks up sticky entries, if there's already an entry for backup server, the connection is sent to the standby rserver.

- If a new client request (connection) doesn't match any sticky entry for backup rserver ACE forwards this request to primary.

Let me know if you have any questions.

Kanwal
