IBM SAN768B, Инструкция по установке, обслуживанию и эксплуатации, Страница: 34 / 208

Hardware components
The SAN768B 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 512 Fibre Channel ports.
v
Two slots for control processor blades (CP8):
– A single active CP8 blade can control all 512 ports in the chassis.
– The standby CP8 blade assumes control of the SAN768B if the active CP fails.
v
Two slots for core switch blades (CR8):
– CR8 blade interconnects all port blades
– Two inter-chassis link (ICL) connectors per blade to connect to another chassis
– Both CR8 blades are active
v
Modular hot-swappable port blades:
– 16-port, 8-Gbps blades (FC8-16)
– 32-port, 8-Gbps blades (FC8-32)
– 48-port, 8-Gbps blades (FC8-48)
– 64-port 8-Gbps blades (FC8-64)
– 6-port, 10-Gbps blades (FC10-6)
v Modular hot-swappable application blades:
– FR4-18i: 18-port (16 FC + 2 GbE), up to 4 blades per chassis, supporting Fibre
Channel Routing Services and FCIP
– FX8-24: 24-port (12 FC, 10 GbE, 2 10GbE) FCIP extension blade enabling long
distance communication over existing IP infrastructure
– FCOE10-24: 24-port (24 10GbE) CEE-based FCoE blade enabling enhanced
connectivity using existing Ethernet infrastructure. This blade cannot be used
in the same chassis as the high density port blade FC8-64 or any of the
application blades (FX8-24, FR4-18i, or FS8-18).
v Modular hot-swappable encryption blades:
– FS8-18: 16-port, up to 4 blades per chassis, supporting data cryptographic
(encryption/decryption) and data-compression capabilities.
v
Modular hot-swappable field replaceable units (FRUs):
– Three blower assemblies
– Up to four power supplies
– Two WWN cards
– Small Form-factor Pluggable (SFP, SFP+, and mSFP) optical transceivers. SFP
transceivers support speeds of 1, 2, and 4 Gbps. SFP+ and mSFP transceivers
support speeds of 2, 4, and 8 Gbps.
– Extended Form-factor Pluggable (XFP) optical transceivers (10-Gbps)
– 1 GbE copper SFP transceivers for the IP ports on the routing blade
Note: The 8-Gbps SFPs and mSFPs auto-negotiate at 2, 4, and 8 Gbps. The
4-Gbps SFPs auto-negotiate at 1, 2, and 4 Gbps.
v
All blades are serviced from the port side of the SAN768B. Blowers, power
supplies, and power cables are serviced from the nonport side.
v Improved cable management using a redesigned cable management comb and
chassis door
