Chapter 1. Introduction
This chapter introduces the features and components of the IBM System Storage
SAN768B-2 fabric backbone. Throughout the remainder of this document, the
product will be referred to as the

Overview of the SAN768B-2
Key features of the SAN768B-2 include:
v Up to 512 16-Gbps external ports in a single chassis, enabling high density SAN
configurations with reduced footprint.
v
Support for 2, 4, 8, and 16 Gbps auto-sensing Fibre Channel ports. Trunking
technology groups up to eight ports to create high performance 128-Gbps ISL
trunks between switches.
v
Support for 10-Gbps FC-type SFPs in 32 and 48 port 16-Gbps port blades, and
also supports 10-GbE SFPs in the FX8-24 and FCOE10-24 application blades. The
two types of SFPs are not interchangeable.
v
The 10-Gbps port speed can be manually configured on any port of the 32- and
48-port 16-Gbps port blades.
v
Support for most of the application, port blade, and control processor (CP)
blades that are supported in the SAN384B-2 (with the exception of the Core
Switch Blade), providing flexible system configurations and fewer types of new
blades.
v
Beginning with Fabric OS v7.0.1, up to nine chassis can be connected with the
use of 4x16-Gbps quad SFP (QSFP) inter-chassis links (ICLs). Fabric OS v7.0.0
permits up to six chassis to be linked.
v
Support for high-performance port blades running at 2, 4, 8, 10, or 16-Gbps,
enabling flexible system configuration.
v
Redundant and hot-swappable control processor and core switch blades, power
supplies, blower assemblies, and WWN cards that enable a high availability
platform and enable nondisruptive software upgrades for mission-critical SAN
applications.
v Universal ports that self-configure as E_Ports, F_Ports, EX_Ports and M_Ports
(mirror ports). 10-Gbps ports are E_Ports only.
v
Diagnostic port (D_Port) functionality.
v
In-flight data cryptographic (encryption/decryption) and data compression
capabilities through the 16-Gbps port blades when configured as ISLs.
v
Fibre Channel over IP (FCIP) functionality through the FX8-24 blade.
v
Fibre Channel over Ethernet (FCoE) capability through the FCOE10-24 blade.
