An enhanced mechanism for the allocation, organization and utilization of high performance block storage metadata provides a stream of data (e.g., in a server system, storage system, DASD, etc.) that includes a sequence of fixed-size blocks which together define a page. Each of the fixed-size blocks includes a data block and a footer. A high performance block storage metadata unit associated with the page is created from a confluence of the footers. Each footer in the confluence of footers has space available for application metadata, which are provided as one or more information units. At least one of the footers includes a Checksum field containing a checksum that covers at least the confluence of footers. This approach is advantageous in that it provides data integrity protection, protects against stale data, and significantly increases the amount of metadata space available for application use.

An enhanced mechanism for the utilization of high performance block storage metadata in applications such as security and data life cycle management. A sequence of fixed-size blocks defines a page, wherein each fixed-size block includes a data block and footer. A current date is compared with an erase date contained in a high performance block storage metadata unit. The metadata unit is created from a confluence of the footers and associated with the page. At least a portion of the page is erased if the erase date is on or before the current date. In one embodiment, the data is erased with a simple overwrite. In another embodiment, the data is erased using a selectable type of secure erase that ensures the erased information cannot possibly be recovered. Preferably, an erase confirmation (e.g., erase_status and/or erase_completed_date) is written into the metadata unit upon successful completion of the erase step.

System control of compression and decompression of data based upon system aging parameters, such that compressed data becomes a system managed resource with a distinct place in the system storage hierarchy. Processor registers are backed by cache, which is backed by main storage, which is backed by decompressed disk storage, which is backed by compressed disk storage then tape, and so forth. Data is moved from decompressed to compressed form and migrated through the storage hierarchy under system control according to a data life cycle based on system aging parameters or, optionally, on demand: data is initially created and stored; the data is compressed at a later time under system control; when the data is accessed, it is decompressed on demand by segment; at some later time, the data is again compressed under system control until next reference. Large data objects are segmented and compression is applied to more infrequently used data. A dedicated compression input/output processor (IOP) is controlled by host system defined data structures which include a bus transport mechanism (BTM) which is DMA loaded to the compression IOP storage. The BTM includes a request response control block (RRCB) comprising a compress or decompress operation command, a data out descriptor (DOD) for providing the address of data in host storage that needs to be compressed or decompressed, and data in descriptor (DID) for providing the address in host storage where the resulting decompressed or compressed data is to be stored.

The present invention improves the performance of a storage device by utilizing the special features of different types of volumes. The control part of the storage device constructs a virtual volume in the memory. The virtual volume is constructed by a low-speed volume and a high-speed volume, and has the same size capacity as the low-speed volume. When the application program of the host requests the updating of data, the write data is respectively written into low-speed and high-speed volumes, and a life tag that indicates the storage period is set beforehand in the virtual volume. When the storage period has elapsed, the data is erased from the high-speed volume. The data in the low-speed volume is maintained “as is”. While the data is held in the high-speed volume, access from the host is processed utilizing the data in the high-speed volume.
