| description | A method for implementing cross device redundancy schemes with a single commit by receiving, by a write page allocation unit, a request to allocate data grains; responsive to receiving the request, performing, by the write page allocation unit, an analysis of a predetermined data layout map associated with a grain memory to identify a memory segment; allocating, by the write page allocation unit, a number of data grains to the memory segment, while computing redundancy data associated with the number of data grains; storing the number of data grains and the redundancy data to the memory segment of the grain memory; determining, by the write page allocation unit, whether a storage threshold associated with the grain memory has been satisfied; and responsive to the storage threshold associated with the grain memory being satisfied, transmitting data grains and redundancy data stored in the memory segment to one or more storage devices. |
