32-Port Fibre Channel Storage Services Module

The 32-port Fibre Channel Storage Services Module (SSM) for the Cisco MDS 9000 Family supports up to 32 Fibre Channel ports, provides distributed intelligent storage services, and supports future storage services.

Note Cisco MDS 9500 Series switches running Cisco MDS SAN-OS Release 2.x, 3.x, or NX-OS Release 4.1(1b) support the SSM.

The Fibre Channel ports support hot-swappable Fibre Channel SFP transceivers, which can be short wavelength (SWL) for connectivity up to 1640 ft (500 m), or long wavelength (LWL) for connectivity up to 6.2 miles (10 km). All interfaces are autosensing 1-Gbps/2-Gbps compatible. The ports also support coarse wavelength-division multiplexing (CWDM) SFP transceivers, which can be used for extended long wavelength (EWL) transmission or for CWDM. For more information about SFP transceivers, see the “Supported Transceivers” section on page 1-55.

Each module draws power from the 42 V supplied on the backplane with local DC/DC power converters and regulators.

The control processor on the module provides power-on, offline, and online diagnostics. The control processor can be used to configure devices on the switching module and to gather statistical data from each port.

The control processor monitors the DC/DC power source and temperature. The control processor signals the SSM and displays an alarm on its front panel when it detects a problem.

The front panel of the SSM provides basic status information, such as power-on, self-test running, self-test passed, alarm, and ready.

The binary image for the SSM is downloaded from the supervisor module. Prior to the image download, the control processor on the services module runs from code stored on its local CompactFlash card. The image for an SSM can be specified using the SSI boot variable. For details on how to specify the SSI boot variable, see the Cisco MDS 9000 Family CLI Configuration Guide.

Note Software downloads are only necessary when a revision of the code is needed.

The SSM can force a reset and control whether or not power is applied to the switching module.
