Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 6.2(1)

OL-29201-01

New Software Features in Cisco NX-OS Release 6.2(1)

A minimum of three crossbar fabric modules are required to deliver full line rate and bandwidth for the

switch. A fourth crossbar fabric module is required for N+1 protection.

Each crossbar fabric module connects to 8 switching modules and two supervisor modules. In addition,

each crossbar fabric module supports four 55-Gbps fabric ports connected to each switching module and

one 55-Gbps fabric port connected to each supervisor module.

Supervisor Module

The supervisor module for the Cisco MDS 9710 Director provides control and management functions

for the switch and enables high-performance switching. It supports the following features:

• Nondisruptive software upgrades

• Stateful process restart and failover

• Fully redundant operation

• Support for up to 384 Fibre Channel ports in a single chassis and 1152 Fibre Channel ports in a

single rack

• Support for up to 24 Tbps of Fibre Channel system bandwidth

• Multipathing based on Fabric Shortest Path First (FSPF)

• Ability to dynamically reroute traffic in the event of a switch failure

Each supervisor module is half the width of the chassis. Two supervisor modules can be installed

side-by-side in a slot.

Power Supplies

The Cisco MDS 9710 Director supports up to eight hot-swappable 3000-W AC power supplies.

Cisco MDS 9000 48-Port, 16-Gbps Fibre Channel Switching Module

Up to eight Cisco MDS 9000 48-Port 16-Gbps Fibre Channel switching modules can be used in the Cisco

MDS 9710 Director. These modules are hot-swappable and compatible with 2-, 4-, 8-, 16- and 10-Gbps

interfaces, and they support hot-swappable Enhanced Small Form-Factor Pluggable (SFP+) transceivers.

The Fibre Channel switching module has 12 4-port port groups. Each port group is capable of a speed

of 64-Gbps in each direction simultaneously. Ports on this switching module support expansion port (E

port), fabric port (F port), fabric loop port (FL port), SPAN destination port (SD port), and (TE port) port

mode.

Individual ports can be configured with Cisco 16-Gbps,8-Gbps or 10-Gbps shortwave or longwave SFP+

transceivers. Each port supports 500 buffer credits with no additional licensing required. With the Cisco

Enterprise Package, up to 4095 buffer credits can be allocated to an individual port.
