SAN Extension Modules
This section describes the SAN Extension modules supported by the IBM c-type
SAN switches and directors switches:

IBM c-type SAN Director 24/10 port SAN Extension Module
The IBM c-type SAN Director 24/10 port SAN Extension Module provides a high
performance, flexible, unified platform for deploying enterprise class disaster
recovery and business continuance SAN extension solutions. The MDS 24/10 port
SAN Extension Module is supported on IBM c-type SAN switches and directors.
With 24 line rate 2-, 4-, 8-, 10-, and 16 Gbps Fibre Channel ports and eight 1 and
10GE or two 40GE Fibre Channel over IP (FCIP) ports, this module enables large
and scalable deployment of SAN extension solutions. The SAN extension module
has two independent service engines that can each be individually and
incrementally enabled to scale as business requirements expand. The SAN
extension module supports the full range of services available on other IBM c-type
SAN Director Fibre Channel switching modules, including virtual SAN (VSAN),
security, and traffic management services. The FCIP module uses IBM expertise
and knowledge of IP networks to deliver outstanding SAN extension performance,
reducing latency for disk and tape operations with FCIP acceleration features,
including FCIP write acceleration and FCIP tape write and read acceleration.
Hardware-based encryption helps secure sensitive traffic with IP Security (IPsec),
and hardware-based compression dramatically enhances performance for both high
and low speed links, enabling immediate cost savings in expensive WAN
infrastructure. Multiple FCIP interfaces within a single engine or across service
engines can be grouped into a port channel of up to 16 links for high availability
and increased aggregate throughput.

Module, see the IBM c-type SAN Director 24/10 port SAN Extension Module for
IBM c-type SAN Switches and Directors Datasheet.
Note: In NX-OS Release 7.3(0)DY(1), 40GE IP Storage interfaces are not supported.
