Single-Fabric Topology for Disk

A single-fabric topology in which the data from the HR server is forwarded to the Cisco MSM-18/4 module, Cisco MDS 922i switch or SSN-16 module. The Cisco MSM-18/4 module, Cisco MDS 9222i switch or SSN-16 module can be anywhere in the fabric. 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 disk.

Note SME disk also supports dual-fabric topology with which the data can be encrypted on all the paths.

Disk devices should be connected to core switches, such as an MDS 9500 Series switch or an MDS 9222i switch, running on Cisco NX-OS Release 5.2(1) or later.

Encryptions are transparent to the hosts and storage devices. These services are available for devices in any virtual SANs (VSANs) in a physical fabric and can be used without rezoning.
