IBM SAN768B-2, Installation, Service And User Manual

Hardware components
The SAN768B-2 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:
v Up to eight hot-swappable port blade assemblies can be configured in a single
chassis, delivering up to 384 16 Gbps Fibre Channel ports.
v
Two slots for control processor blades (CP8):
– A single active CP8 blade can control all 384 ports in the chassis.
– The standby CP8 blade assumes control of the SAN768B-2 if the active CP
fails.
v
Two slots for core switch blades (CR16-8):
– CR16-8 blade interconnects all port blades
– Inter-chassis link (ICL) connectors to connect to as many as four neighboring
chassis
– Both CR16-8 blades are active
v
Modular hot-swappable port blades:
– 64-port, 8-Gbps blades (FC8-64)
– 32-port, 16-Gbps blades (FC16-32)
– 48-port, 16-Gbps blades (FC16-48)
v Modular hot-swappable application blades:
– FX8-24: 24-port (12 FC, 10 GbE, 2 10GbE) FCIP extension blade enabling long
distance communication over existing IP infrastructure.
v Modular hot-swappable field replaceable units (FRUs):
– Three blower assemblies
– Up to four power supplies
– Two WWN cards
– Blades use small form-factor pluggable (SFP+, and mSFP) optical transceivers.
SFP+ and mSFP transceivers support speeds of 2, 4, 8, 10, or 16 Gbps.
Note:
The 8-Gbps SFP+s and mSFPs auto-negotiate at 2, 4, and 8 Gbps. The
16-Gbps SFP+s auto-negotiate at 4, 8, and 16 Gbps. The 10 Gbps speeds
must be manually set and require special 10 Gbps SFP+ transceivers.
– QSFP-based inter-chassis link (ICL) cabling running at 64 Gbps (four 16 Gbps
clustered in a single quad connector and cable).
v
Blades are serviced from the port side of the SAN768B-2. Blowers, power
supplies, and power cables are serviced from the nonport side.
v World Wide Name (WWN) cards on the nonport side, to maintain
chassis-specific information such as WWNs, IP addresses, and summary status
information of each port blade and power supply through LEDs
v
Constant intake and FRU temperature monitoring
v Redundant AC primary power connections to ensure high availability. Each
power supply has its own connector.
Note: Airflow in the SAN768B-2 is from the non-port (non-cable) side to the port
(cable) side and out the exhaust vent.
Figure 1 on page 4 shows a sample configuration of the port side of the
SAN768B-2, with the chassis door removed.
