Overview
Hardware components
The DC Director features a modular and scalable mechanical construction that allows a wide range of
flexibility in installation, fabric design, and maintenance. The chassis may be mounted with the cables
facing the front of the equipment rack or to the rear, and consists of the following:
•
Up to eight hot-swappable Director blade assemblies can be configured in a single chassis, delivering
up to 384 FC ports
•
Two slots for CP blades (CP8):
• A single active CP8 blade can control all 384 ports in the chassis.
• The standby CP8 blade assumes control of the DC Director if the active CP fails.
•
Two slots for core switch blades (CR8):
• CR8 blade interconnects all Director blades
• Two inter-chassis link (ICL) connectors per blade to connect to another DC Director
chassis
• Both CR8 blades are active
•
Modular hot-swappable Director blades:
• 16-port, 8-Gbps blades (FC8-16)
• 32-port, 8-Gbps blades (FC8-32)
• 48-port, 8-Gbps blades (FC8-48)
• 6-port, 10-Gbps blades (FC10-6)
•
Modular hot-swappable application blades:
IMPORTANT:
At the time of this document’s release, the FC4-16IP is not supported in the DC
Director. The FC4-16IP will be supported in a future version of Fabric OS.
• FR4-18i, 18-port (16 FC + 2 GbE), up to four blades per chassis, supporting FCR Services and FCIP
• FC4-16IP, 16-port (8 FC + 8 GbE), up to four blades per chassis, supporting iSCSI bridging)
•
Modular hot-swappable field replaceable units (FRUs):
• Three blower assemblies
• Up to four power supplies
• At 240 VAC, two power supplies are required to provide redundancy, although the DC Director can
be fully powered with a single power supply at 240 VAC.
At 110 VAC, four power supplies are required when using the FR4-18i, or FC4-16IP blades.
• Two redundant WWN cards on the non-port side, to maintain chassis-specific information such as
WWNs, IP addresses, and summary status information for each Director blade and power supply
through LEDs
• 4Gb and 8Gb Small Form-factor Pluggable (SFP) optical transceivers (4Gb SFPs operate at 1Gb,
2Gb or 4Gb. 8Gb SFPs operate at 2Gb, 4Gb or 8Gb.)
• Extended Form-factor Pluggable (XFP) optical transceivers (10Gbps)
•
All blades are serviced from the port side of the DC Director. Blowers, power supplies, and power
cables are serviced from the non-port side
•
Improved cable management using a re-designed cable management comb and chassis door
•
Constant intake andField-replaceable Unit (FRU) temperature monitoring
•
Redundant AC primary power connections to ensure high availability. Each power supply has its own
connector, so the number of primary power connections varies from two to four.
