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： Deploying a software service. A defined software service offering is selected from a plurality of defined software service offerings. An instantiation order for deploying the selected defined software service offering on a corresponding computer system is generated. Each defined software service offering comprises a software service definition and at least one defined software policy. One selected from the group consisting of the software service definition, the software policy, and a combination thereof, provides a hardware configuration for the software service, a software configuration for the software service, and a managing policy for the software service. The instantiation order of the software service for execution on the computer system is created based on the hardware configuration, the software configuration and the managing policy.

摘要： A method for supporting simultaneous mixed protection modes for a write operation. The method includes receiving a write request that includes write data, and is received from one of a plurality of requestors. At least one of the requestors does not support data integrity protection. It is determined if data integrity protection is required for the write operation. It is additionally determined if the data integrity protection is supported by the requestor. Once the determination is made, the data integrity protection value is calculated if data integrity protection is required and is not supported by the requestor. The write data is encoded with the data integrity protection value prior to being written. If the requestor supports data integrity protection, then data integrity protection values are applied to the write data prior to writing the data to the external storage.

摘要： An encryption method encrypts a clear text twice using a first encryption engine to produce a first cipher text and a second encryption engine to produce a second cipher text. The method compares the first cipher text with the second cipher text, or compares a checksum of the first cipher text with a checksum of the second cipher text. If the comparison succeeds, the method transmits the data. In some embodiments, the method uses a first instance of an encryption key to produce the first cipher text and a second instance of the encryption key to produce the second cipher text.
