Abstract
Parallel, coordinated, and optimized access of real Base and Alias DASDs by one or more virtual machines, each utilizing one or more virtual Base and Alias DASDs. Each of a plurality of virtual machines defines a virtual Base DASD device and a modified operating system may coordinate the virtual machine activity on real Base and Alias devices to maximize overall system throughput. In more complex embodiments, one or more virtual machines define one or more virtual Bases and associated virtual Alias devices in which case wherein the embodiments described coordinate their activity on one or more real Base and Alias devices to maximize overall system throughput.
