Abstract
System and method embodiments are provided for managing storage systems. In an embodiment, a network component for managing data storage includes a storage interface configured to couple to a plurality of storage devices; and a vector-direct memory access (DMA) cache-exclusive OR (XOR) engine coupled to the storage interface and configured for a multiple parities convolution codes (MPCC) erasure coding to accelerate M parities parallel calculations and the erasures cross-iterations decoding, wherein a single XOR-engine with caches and a vector-DMA address generator is shared by the MPCC erasure coding engine for pipelining external dual data rate (DDR4) memory accesses, where M is a positive integer greater than two.
