Abstract: A data storage system is provided that is configured to achieve end-to-end data protection. The system includes a server running a storage archive manager with a first fixity support module, and the system includes a tape drive running a second fixity support module. During operations, the storage archive manager reads a data file with associated fixity information from a disk storage device, and the storage archive manager builds a set of blocks from the data file for writing to the tape drive. The first fixity support module checks fixity of the set of blocks by processing the fixity information associated with the data file. The processing of the fixity information includes determining whether data in the set of blocks is out of order relative to data in the data file or whether data in the set of blocks is corrupt relative to the data in the data file.

Abstract: An intelligent data storage manager is operational in a virtual data storage system that uses a storage element to store data for a host processor. The storage manager includes a host interface and a controller. The host interface receives a virtual volume having virtual blocks from a host processor. The controller sequentially segments the virtual volume into data pages. Each data page includes virtual blocks of the virtual volume. The controller generates a meta data page associated with the virtual volume to map the data pages to the virtual blocks of the virtual volume. The controller uses the meta data page to selectively store the data pages onto the storage element. The storage element has a partitioning configuration and the amount of the virtual blocks included by each data page is a function of the partitioning configuration of the storage element. The meta data page associated with the virtual volume includes meta data page records.
