  1. The customer has DataPower appliances deployed using either an Active/Passive, Active/Standby or Active/Active configuration. All DataPower appliances in any of these configurations have unique IP addresses.
  2. DPOD server is installed once and is configured to monitor all DataPower appliances (active, standby and passive). HANAN - WHY ONCE? WE HAVE ACTIVE AND PASSIVE. IF THIS IS TRUELY ONCE THEN THE PHRASING SHOULD BE DIFFERENT AND TELL THE CUSTOMER TO BRING UP THE SAME SERVERS ON A DIFFERENT VM RACK
  3. 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).
  4. The customer has storage replication capabilities to replicate DPOD disks based on the disks’ replication policy described above.
  5. The customer has a 3rd party software tool or scripts that can:

...

6. The passive DPOD server is not running when business is as usual (since in this scenario , since disks replication is required and it has the same IP address as the active primary DPOD server).

During a disaster:

  1. The customer's DR software should Identify a failure in DPOD failure primary server (e.g. by pinging access IP, sampling user interface URL or both).
  2. The customer's DR software should launch the passive DPOD server using the same IP address as the failed primary server (or change the IP address if not already configured that way).

...

  • As the passive DPOD 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 has the same IP address as the primary one, access to DPOD console will be with the same URL.

Assumptions:

  1. The customer has DataPower appliances deployed using either an Active/Passive or Active/Stand-by configuration. All DataPower appliances in any f of these configuration must configurations have unique IP addresses.
  2. DPOD is server is installed once and is configured to monitor all DataPower appliances (active, standby and passive). HANAN - WHY ONCE? WE HAVE ACTIVE AND PASSIVE. IF THIS IS TRUELY ONCE THEN THE PHRASING SHOULD BE DIFFERENT AND TELL THE CUSTOMER TO BRING UP THE SAME SERVERS ON A DIFFERENT VM RACK
  3. All DPOD network services (NTP, SMTP, LDAP etc.) have the same IP address addresses even after failover (otherwise a post configuration script is required to be run by the DR software).
  4. The customer has storage replication capabilities to replicate DPOD disks based on the disks’ replication policy described above.
  5. The customer has a 3rd party software tool or scripts that can:
    • Identify unavailability of the primary DPOD server/s.
    • Launch the a passive DPOD serversserver using a different IP address to than the active primary one.

6. The passive DPOD server is not up running when business is as usual, since disks replication is required.
