High availability
The following features contribute to the 4/256 SAN Director high-availability design:
• Redundant, hot-swappable components
• Redundant power supply and blower assembly subsystems
• Enhanced data integrity on all data paths
• Fabric Shortest Path First (FSPF) rerouting around failed links
• Integration with Simple Network Management Protocol (SNMP) managers
• Automatic control processor failover
• Nondisruptive “hot” software code loads and activation
• Easy configuration, save, and restore
• Hot-swappable World Wide Name (WWN) card
The high-availability software architecture of the 4/256 SAN Director 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.
