## About Auto Key Replication of Keys Across Data Centers

Note Auto key replication of keys across data centers is applicable only for SME tape.

The auto replication of media keys enables the moving of tapes from one data center to another. The replication of keys allows the same tape media to be accessed by more than one SME cluster. In most cases, the SME clusters are located in different locations, such as a primary data center and a disaster recovery site. SME allows you to automatically replicate the media keys from one SME cluster to one or more clusters. The automated process of replicating keys eliminates the need for the manual key export and import procedures. The media key auto-replication is configured on per tape volume group basis.

One KMC manages all the data centers and the replicated keys are stored on the KMC.
