18/4-Port Multiservice Module

The Cisco MDS 9000 Family 18/4-port Multiservice (MSM-18/4) module 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 provides18 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 supports hardware-based encryption and it is required to run the Storage Media Encryption (SME) which, is a part of the Cisco NX-OS. For more information on SME, see the Cisco MDS Storage Media Encryption Guide.

The MSM-18/4 supports SAN extension over IP and is compatible with current SAN extension products, such as MPS-14/2, 9216i, and IPS. The MSM-18/4 provides an integrated next generation 4-Gbps FC platform for SAN extension. The MSM-18/4 module supports Internet Protocol version 6 (IPv6) as mandated by the U.S. Department of Defense (DoD), Japan, and China. The IPv6 support is provided for FCIP, iSCSI, and management traffic routed in-band and out-of-band.

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