About Cisco Storage Media Encryption Chapter 1 Product Overview Send documentation comments to [email protected] 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: • Cisco MDS 9000 Family 18/4-port Multiservice Module (MSM-18/4) • Cisco MDS 9222i Multiservice Module Switch Single-Fabric Topology Figure 1-3 shows a single-fabric topology in which the data from the HR server is forwarded to the Cisco 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. Figure 1-3 shows encrypted data from the HR server is compressed and stored in the HR tape library. Data from the Email server is not encrypted when backed up to the dedicated Email tape library.
