concurrently upgraded. The combination of high port count and the
FlexPar feature enables an enterprise to use the director at the core of
both small and large SAN fabrics. For example:
• Large fabrics built around the director require fewer fabric
elements (directors and switches) and ISLs. Large fabrics benefit
from deterministic non-blocking performance, less ISL
congestion, and better cable management. This performance is
not possible from a fabric constructed with smaller port-count
switches interconnected with multiple ISLs. Refer to General
Fabric Design Considerations for information.
• Smaller fabrics or SAN islands built around the director (but
separated through FlexPars) benefit from better resource
utilization because port configurations are flexible to
accommodate change and the hardware does not require
over-provisioning for growth. The FlexPar feature enables
additional fabric ports to be added to a partition on demand,
without interrupting fabric traffic. Refer to Inter-FlexPar Routing
for information.
The director provides a modular design that enables quick removal
and replacement of FRUs, including:
• Front bezel with green power (SYSTEM ON) and amber error
(SYSTEM FAULT) LEDs.
• Redundant CTP (1.0625, 2.1250, and 10.2000 Gbps operation)
logic cards.
• Redundant and shared switching module (SWM) logic cards.
The director provides a variable, full-duplex, packet-switching
bandwidth that scales up to 640 Gbps (four SWMs at 160 Gbps
per module).
• Redundant cooling fan trays (upper and lower, front and rear).
• Power tray with redundant, load-sharing power supplies and AC
power switches.
• Upper and lower cable trays.
• A minimum of one to a maximum of eight Fibre Channel line
modules (LIMs). Each LIM provides the interface to attach up to
four optical paddles as follows:
