MIB module to manage Storage Media Encryption (SME) service. SME is an encryption service provided by an encryption node residing on a linecard in a storage device. It receives clear-text data from host, encrypts it, then sends it to be written to tape or disk. It does the reverse in the opposite direction so the service is completely transparent to the host. The purpose of this service is to enhance data security in case the tape or disk is lost or stolen. As with any important service, user requires that it provides some level of fault tolerant in a graceful manner. SME provides this by allowing encryption nodes to be grouped into cluster. Nodes in the same cluster immediately pick up the work of a failed node so user does not see service disruption.
