Cisco MDS SanOS Troubleshooting Guide -- Managing Storage Services Modules
This chapter describes how to manage the Storage Services Module (SSM) and provides information about SSI images.
The 32-port Fibre Channel Storage Services Module (SSM) for the Cisco MDS 9000 Family supports up to 32 Fibre Channel ports and provides distributed intelligent storage services.
|Note:||Cisco MDS 9500 Series switches running Cisco MDS SAN-OS Release 2.0(2b) or later support the SSM module.|
The SSI image for the SSM is downloaded from the supervisor module. The image for an SSM can be specified using the SSI boot variable.
|Note:||The SSM can operate as a 32-port Fibre Channel switching module with the standard Cisco SAN-OS images for Release 2.1(2) or later. You need the SSI image if you use intelligent storage services.|
The following table lists the features supported for the SSM :

|2.0(1b)||2.0(2b), 2.0(3), 2.0(4), and 2.0(4a)||2.1(1a)||2.1(2) and later|
