<p>The network attached virtual tape storage subsystem interconnects a plurality of tape devices (TD1-TD5) with a plurality of data processors via a high bandwidth switching network (FN) to implement a virtual, distributed tape data storage subsystem. The virtual, distributed tape data storage system realizes multiple virtual devices, which are available to any of the data processors and the bandwidth of the system is scalable and can be changed on demand. The virtual tape storage subsystem is managed by a system controller which contains a plurality of software elements. The use of a networked storage manager enables the tape devices to be managed as a pool and yet attach the tape devices directly to the network as individual resources. The networked storage manager must provide the mechanism for the enterprise management to control tape device allocation and configuration as well as other functions, such a tape cartridge movement and data migration.</p> |
