摘要： An enhanced mechanism for providing data protection for variable length records utilizes high performance block storage metadata. In an embodiment, an emulated record that emulates a variable length record, such as a Count-Key-Data (CKD) record or an Extended-Count-Key-Data (ECKD) record, is generated by a Host Bus Adapter (HBA) of a mainframe system. The emulated record comprises a sequence of extended fixed-length blocks, each of which includes a data block and a footer. A confluence of the footers defines a high performance block storage metadata unit associated with the emulated record and includes a checksum that covers all data blocks and all footers of the entire emulated record. In one embodiment, the checksum is checked during transit of the emulated record between a HBA and a storage subsystem (e.g., by the HBA when the emulated record is received from the storage subsystem, and/or by a switch in the data transfer path), during a hardening step when writing the emulated record to a disk, and/or during a verification step when reading the emulated record from the disk.

摘要： A data storage system writes data supplied from a host to data storage in accordance with write I/O of an owning application. A workload manager directs the processing of the supplied data in accordance with the write I/O of the owning application, provides service workload identification describing the write I/O, a storage subsystem control adds the service workload identification to record set information for the data, and a journal management system stores the record set information in a journal. The journaled information, for example, may be employed for performing forensic analysis of data corruption events or to perform security audits, etc.

摘要： Providing extended or end-to-end data integrity through layers of a system. In one aspect, information is to be transmitted between an application end of the system and a physical storage medium that stores the information for a database of the system, the information to be transmitted via a database server in a database server layer of the system. At least a portion of data protection is provided for the information, the data protection causing the information to be protected from corruption between a system layer and the physical storage medium, where the system layer is a separate layer provided closer to the application end of the system than the database server layer.

摘要： 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.
