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.
Cisco MDS 9000 Series switches running Cisco SAN-OS Release 3.2(2c) or later or Cisco NX-OS
Note
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.
For additional information, refer to the Cisco MDS 9500 Series Hardware Installation Guide.
Cisco MDS 9222i Multiservice Modular Switch
The Cisco MDS 9222i Multiservice Modular switch includes an integrated supervisor module (in slot 1)
that provides the control and management functions of the Cisco MDS 9222i switch and it provides an
18-Port Fibre Channel switching and 4-Port Gigabit Ethernet IP services module. The Cisco MDS 9222i
built-in supervisor module provides multiple communication and control paths to avoid a single point of
failure. The Cisco MDS 9222i supervisor module has a PowerPC PowerQUICC III class processor, 1 GB
of DRAM, and an internal CompactFlash card that provides 1 GB of storage for software images.
The Cisco MDS 9222i switch includes a modular expansion slot to host Cisco MDS 9000 Family
switching and services modules. For additional information, refer to the Cisco MDS 9200 Series
Hardware Installation Guide.
Note
The Cisco MDS 9222i switch requires Cisco SAN-OS Release 3.2(2c) or later or Cisco NX-OS Release
4.x or later for SME tape.
The Cisco MDS 9222i switch requires Cisco NX-OS Release 5.2(1) for SME disk.
