PAN Server Portability software by Egenera provides a high availability failover capability that automaticallyl moves an application service from a failed server to a recovery server.
PAN Server Portability supports the following two types of high availability failover:
- Hardware failover recovers from a server failure
- Application failover recovers from a software failure or a system monitoring trigger
PAN Server Portability lets you add custom failover rules and recovery procedures, so you can enforce the specific SLA requirements needed to keep your business running.
PAN Manager’s n+1 approach lets you can allocate just one server, or a pool of servers, to provide backup for an entire PAN System. This feature eliminates the need to maintain a 1-to-1 backup server for each application. In addition, because PAN Manager can repurpose a server in minutes, you can use the backup server for non-critical workloads instead of letting it sit idle.
When PAN Server Portability performs a failover operation, it uses all of PAN Manager’s integrated capabilities to perform application recovery in minutes. For example:
- The foundation services provide the communication and I/O virtualization capabilities that enable applications to migrate to any server within the PAN system
- The logical server definition ensures that each application service retains its network, storage, and peripheral resources
- PAN Server Portability software automatically performs all of the failover steps in response to either an administrator action or an automated policy event
