High availability
The following features contribute to the DC04 SAN Director's high-availability design:
• Redundant, hot-swappable CP8 and CR4S-8 blades and FRUs
• Enhanced data integrity on all data paths
• FSPF re-routing around failed links
• Integration with SNMP managers
• Automatic CP and core blade failover
• Nondisruptive, hot software code loads and activation
• Easy configuration, save, and restore
• Hot-swappable WWN cards
The high-availability software architecture of the DC04 SAN Director provides a common framework
for all applications that reside on the system, allowing global and local states to be maintained
through 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 CP blade, facilitates software
upgrades, prevents extraneous switchover activity, closes and flushes streams, provides flow control
and message buffering, and supports a centralized active and standby state.
Reliability
The DC04 SAN Director uses the following error detection and correction mechanisms to ensure
reliability of data:
• Data protected by the Error Detection and Correction mechanism, which checks for EDFI, such
as CRC, parity checking, checksum, and illegal address checking
• POST
