3. You are expected to have an Active/Passive software or another mechanism in place to identify when DPOD server node becomes inactive and launch a new one in an active cluster member.
...
- As the passive DPOD server has node has the same IP, all DataPower appliances will be able to access it.
- Since all DataPower appliances will have the same IP addresses - DPOD can continue to sample them.
- Since the passive DPOD server has node has the same IP address as the primary one, access to DPOD console will be with the same URL.
...
- The customer has DataPower appliances deployed using either an Active/Passive or Active/Stand-by configuration. All DataPower appliances in any of these configurations have unique IP addresses.
- DPOD server is node is installed once and is configured to monitor all DataPower appliances (active, standby and passive).
- All DPOD network services (NTP, SMTP, LDAP etc.) have the same IP addresses even after failover (otherwise a post configuration script is required to be run by the DR software).
- The customer has storage replication capabilities to replicate DPOD disks based on the disks’ replication policy described above.
- The customer has a 3rd party software tool or scripts that can:
- Identify unavailability of the primary DPOD servernode.
- Launch a passive DPOD server node using a different IP address than the primary one (usually on a different physical hardware).
6. The passive DPOD server node is not running when business is as usual, since disks replication is required.
...
DPOD will be available in the following way:
- Although the passive secondary DPOD server node has a different IP address, all the DataPower appliances will still be able to access it since their internal host aliases pointing to DPOD will be replaced (step 5 above).
- As all DataPower appliances retain the same IP addresses - the passive DPOD server that was just became active can continue to sample them.
- Although the passive DPOD server secondary DPOD node has a different IP, all users can access DPOD’s web console because its DNS name has been changed or it is behind an NLB (step 4 above).
