Abstract
The network attached virtual tape storage subsystem interconnects a plurality of tape devices with a plurality of data processors via a high bandwidth switching network 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 including: resource allocation, resource configuration, and resource management. 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 as tape cartridge movement and data migration.
