Single-Fabric Topology for Tape

Figure 2-3 shows a single-fabric topology in which the data from the HR server is forwarded to the Cisco MSM-18/4 module. The Cisco MSM-18/4 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 tape. SME also tracks the barcodes on each encrypted tape and associates the barcodes with the host servers.

Figure 2-3 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.

Note Tape devices should be connected to core switches such as an MDS 9500 Series switch or MDS 9222i switch running Cisco SAN-OS Release 3.2(2c) or later or Cisco NX-OS Release 4.x or later.

Encryption and compression services 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.
