Port numbering and trunking port groups (Continued)TABLE 2
Blade Port numbering Trunking port groups
FS8-18 blade • 16 FC ports: 0 through 15 from bottom to top.
• Two 10/100/1000 BaseT ports: GE0 and GE1
from the bottom.
• Trunk group 0: FC ports 0-7
• Trunk group 1: FC ports 8-15
FX8-24 blade • FC ports labeled FC on the front panel: 0
through 11 in two vertical columns of six ports
starting from the bottom left and bottom right
in the lower group of 12 ports.
• Two 10-GbE ports labeled 10GE on the front
panel: 0 and 1 in the left column just above
the FC ports.
• 1-GbE ports labeled GE on the front panel: 0
through 9 in both columns above the FC and
10GE ports.
• Trunk group 0: FC ports 0-1
• Trunk group 1: FC ports 6-7
• Trunk group 2: FC ports 2-5 and 8-11
High availability
The following features contribute to the high availability the device:
• Redundant, hot-swappable FRUs, including blades, power supplies, blowers, and WWN cards
• 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
The high availability software architecture 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 control processor, facilitates software
upgrades, prevents extraneous CP failover activity, closes and flushes streams, provides flow control
and message buffering, and supports a centralized active and standby state.
Reliability
The device uses the following error detection and correction mechanisms to ensure reliability of data:
• Error Detection and Correction over main control processor memory.
• Error Detection and Correction mechanism, which checks for encoder errors and fault isolation
(EDFI), such as cyclic redundancy checking (CRC), parity checking, checksum, and illegal address
checking.
• Power-on self-test (POST).
• Dual control processors that enable hot, nondisruptive fast firmware upgrades.
• One serial port and two Ethernet ports (on each control processor) for management and for service.
Offline control processor diagnostics and remote diagnostics simplify troubleshooting. The standby
