Abstract
Exemplary method, system, and computer program product embodiments for block based end-to-end data protection for extended count key data (ECKD) in a computing environment are provided. In one embodiment, by way of example only, information units (IU's) are aligned in a block boundary format. Block protection trailer data is added to each one of the IU's. Additional system and computer program product embodiments are disclosed and provide related advantages.
Claims18
A system for block based end-to-end data protection for extended count key data (ECKD) in a computing environment, comprising:
- at least one processor device, operable in the computing storage environment,
- a storage controller, operable by the at least one processor device, and
- wherein the at least one processor device is adapted for:
- aligning at least one of a plurality of information units (IU's) in a block boundary format, and
- adding block protection trailer data to each one of a block of the at least one of the plurality of IU's.
A computer program product for block based end-to-end data protection for extended count key data (ECKD) by a processor device, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
- a first executable portion for aligning at least one of a plurality of information units (IU's) in a block boundary format;
- and
- a second executable portion for adding a block protection trailer data to the at least one of the plurality of IU's.
