Supported Topologies

Cisco SME supports a single-fabric topology. The Cisco MSM-18/4 module and the MDS 9222i switch
provides the Cisco SME engines used by Cisco SME to encrypt and compress data-at-rest. Multiple
modules can be deployed in a Fibre Channel fabric to easily scale-up performance, to enable simplified
load balancing, and to increase availability. In a typical configuration, one MSM-18/4 is required in each
Cisco SME cluster.
Cisco SME clusters include designated backup servers, tape libraries, and one or more MDS switches
running Cisco SAN-OS Release 3.2(2c) or later or NX-OS 4.x. One cluster switch must include an
MSM-18/4 module. With easy-to-use provisioning, traffic between any host and tape on the fabric can
utilize the Cisco SME services.
Required Cisco SME engines are included in the following Cisco products:

MSM-18/4. The Cisco MSM-18/4 can be anywhere in the fabric. Cisco SME does a one-to-one mapping
of the information from the host to the target and forwards the encrypted data to the dedicated HR tape.
Cisco SME also tracks the barcodes on each encrypted tape and associates the barcodes with the host
servers.
