Overview High Availability The following features contribute to the SAN Director 2/128 high-availability design: ■ Redundant, hot-swappable components ■ Redundant power and cooling subsystems ■ Enhanced data integrity on all data paths ■ Fabric Shortest Path First (FSPF) rerouting around failed links ■ Integration with SNMP managers ■ Automatic control processor fail over ■ Nondisruptive "hot" software code loads and activation ■ Easy configuration, save, and restore The high-availability software architecture of the SAN Director 2/128 provides a common framework for all applications that reside on the system, allowing global and local states to be maintained enough to manage any component failure. High-availability elements consist of the High Availability Manager, the heartbeat, the fault/health framework, the replicated database, initialization, and software upgrade. The High Availability Manager controls access to the standby control processor, facilitates software upgrades, prevents extraneous switchover activity, closes and flushes streams as needed, provides flow control and message buffering, and supports a centralized active and standby state. 20 SAN Director 2/128 Installation Guide
