Abstract
A computer-implemented method, according to one embodiment, includes: sequentially adding metadata information that has been extracted from a received write command to a metadata buffer, and adding parity information that has been extracted from the received write command to a parity buffer. The data corresponding to the received write command is also sent to memory. A determination is made as to whether an open segment in the memory which corresponds to the write command has been filled. In response to determining that the open segment has been filled, the parity buffer is updated with the metadata information included in the metadata buffer. Moreover, the metadata information is destaged from the metadata buffer and parity information is destaged from the parity buffer to a physical storage location in the memory.
