Active / Active Operation Concurrent I/O service from single or multiple servers to dual

controllers increase performance

Active / Active Failover• If a controller fails, “failover” is transparently initiated

• Surviving controller assumes the failed controller’s address and services I/O’s from both servers

Active / Active Failback When the failure is fixed, “failback” is automatically initiated

Failover / failback is transparent to users and applicationsand enables failure tolerant systems
