Caching Services Module

The Caching Services Module (CSM) provides virtualization services that allow the Cisco MDS 9000
Family switches to reallocate physical resources as virtual resources for increased efficiency. The CSM
receives and sends data through the switch backplane. It has two disk drives, two internal batteries for
backup in case of power failure, and no external ports.
CSMs must be implemented in pairs in the fabric to provide redundancy and backup. Only two or more
CSMs in a fabric are supported. However, the CSMs do not have to be installed in the same switch.
The CSM may shut down because of the software, an external power failure, or the module separated
from the backplane while it still had power. The CSM automatically backs up the data in memory to the
disk drives and then shuts down. The CSM batteries provide adequate power to back up data without
external power.
The Cisco MDS 9513 does not support the CSM.
