Channel Switching Module meets the high performance needs for flash memory and Non-Volatile Memory
Express (NVMe) over Fiber Channel SANs. The switching module has a built in Network Processing Unit
(NPU) for inline analytics. This module also supports hot-swappable Enhanced Small Form-Factor Pluggable
(SFP+) transceivers.
Individual ports can be configured with Cisco 64-Gbps, 32-Gbps, and 16-Gbps SFP+ transceivers. Each port
supports 1000 buffer credits when configured as E port. With the Cisco Enterprise Package license, up to
16000 buffer credits can be allocated to an individual port when all other ports in the port group are configured
with minimum BB credits, enabling full link bandwidth over long distances with no degradation in link
utilization.
Cisco MDS 9700 Series Supervisor-4 Module (DS-X97-SF4-K9) and Cisco MDS Crossbar Fabric-3 Switching
Modules (depending on the chassis type) are required for Cisco MDS 9700 48-Port 64-Gbps Fiber Channel
Switching Module to function.
In Cisco MDS NX-OS Release 9.2(1), the SAN Analytics feature is not supported on Cisco MDS 9700 48-Port
64-Gbps Fiber Channel Switching Module.
For more information on the Cisco MDS 48-Port 64-Gbps Fiber Channel Switching Module, see the Cisco
MDS 9700 48-Port 64-Gbps Fibre Channel Switching Module datasheet.
Note
The 64-Gbps module supports Forward Error Correction (FEC) on links configured for 16-Gbps speed only
with Transmitter Training Signal (TTS). This is a change from the 16 Gbps and 32 Gbps Fiber Channel
modules. For more information, see the Cisco MDS 9000 Series Interfaces Configuration Guide, Release 9.x.
