Cisco MDS 9000 Family 18/4-Port Multiservice Module

The Cisco MDS 9000 Family 18/4-Port Multiservice module (MSM-18/4) provides 18 autosensing 1-, 2-, and 4-Gbps Fibre Channel ports and four Gigabit Ethernet IP services ports. The MSM-18/4 module provides multiprotocol capabilities such as Fibre Channel, Fibre Channel over IP (FCIP), Small Computer System Interface over IP (iSCSI), IBM Fiber Connectivity (FICON), and FICON Control Unit Port (CUP) management.

The MSM-18/4 module provides 18 4-Gbps Fibre Channel interfaces for high-performance SAN and mainframe connectivity and four Gigabit Ethernet ports for FCIP and iSCSI storage services. Individual ports can be configured with hot-swappable shortwave, longwave, extended-reach, coarse wavelength-division multiplexing (CWDM) or dense wavelength-division multiplexing (DWDM) Small Form-Factor Pluggables (SFPs) for connectivity up to 125 miles (200 km).

The MSM-18/4 module can minimize latency for disk and tape through FCIP write acceleration and FCIP tape write and read acceleration. The MSM-18/4 module provides up to 16 virtual Inter-Switch Link (ISL) connections on the four 1-Gigabit Ethernet ports through tunneling, and provides up to 4095 buffer-to-buffer credits that can be assigned to a single Fibre Channel Port.

The MSM-18/4 provides intelligent diagnostics, protocol decoding, and network analysis tools with the integrated Call Home capability.

Note Cisco MDS 9000 Series switches running Cisco SAN-OS Release 3.2(2c) or later or Cisco NX-OS Release 4.x or later support the MSM-18/4 module for SME tape.
Cisco MDS 9000 Series switches running Cisco NX-OS Release 5.2(1) support the MSM-18/4 and SSN-16 modules for SME disk.
