Forty-eight ports in one slot is what the DS-X9248-256K9 adds to an MDS 9500 chassis: a Cisco MDS 9000 Family 48-port 8-Gbps Fibre Channel switching module for virtualized servers. Traffic switched across the backplane totals 512 Gbps full-duplex, with 1.5:1 oversubscription at the 8-Gbps rate across all ports.
With Arbitrated Local Switching enabled, the module runs 48 line-rate 8-Gbps ports and reaches 768 Gbps full-duplex across locally switched ports. The module fits dense virtual machine clusters with locally mapped storage, and Cisco VMpath tracks paths from the server to storage per virtual machine. FlexSpeed can set up to 24 of the ports to 10 Gbps.
Per-port buffer credits stand at 500, and 4095 is possible on an individual port with the Enterprise Package license. The module and its SFP+ transceivers can be swapped while the system runs. Compatible chassis are all Cisco MDS 9500 Series Multilayer Directors under NX-OS Release 5.2 or later. Weight is 10.5 lb (4.76 kg) and the spare number is DS-X9248-256K9=.
In the same 8-Gbps range are the DS-X9248-48K9 4/44-port module and the DS-X9224-96K9 24-port 8-Gbps module, and more cards are in Cisco interface cards.
