Abstract:
An intelligent data storage manager operational in a virtual data storage system that uses a plurality of high and low performance data storage elements to store data thereon for at least one host processor connected to the virtual data storage system, the intelligent data storage manager comprising:a host interface for receiving a virtual tape volume having a plurality of virtual tape blocks from a host processor; and a controller for sequentially segmenting the virtual tape volume into data pages, wherein each data page includes at least one virtual tape block of the virtual tape volume, wherein the controller generates a meta data page associated with the virtual tape volume to map the data pages to the respective virtual tape blocks of the virtual tape volume, wherein the controller uses the meta data page to selectively store the data pages onto the high and low performance data storage elements; wherein each of the high and low performance data storage elements has a partitioning configuration, wherein the amount of the at least one virtual tape block included by each data page is a function of the partitioning configuration of at least one of the high and low performance data storage elements.
