Abstract

A tape mirror interface comprises an input terminal coupled to at least one input node and capable of receiving data transfer requests, a plurality of output terminals coupled to a plurality of tape storage devices, and a control element coupled to the input terminal and plurality of output terminals. The control element presents the plurality of tape storage devices as separate media devices and selectively controls data transfer in a synchronous mode and a split mode. In the synchronous mode, writes to a target tape storage media are mirrored to a mirrored tape storage media. In the split mode, writes are written to tape storage devices independently.
