System and method to utilize larger block sizes for logical disk and further decompose into smaller physical block sizes for redundant encoding by utilizing erasure coding

Abstract

Disclosed are a method and device in a network for utilizing larger block sizes for a logical disk, and further decomposing into smaller physical block sizes for a redundant encoding by utilizing an erasure coding logic to avoid a read□modify□write operation on a plurality of write operations. The device includes a receiving module, an encoding module, and a transmitting module. The receiving module configured to obtain a read request or a write request of a large block size to a storage unit over a network. In an embodiment, the storage unit comprising a plurality of physical devices of a smaller blocks size that is a divisor of the large block size. The encoding module to encode the received requests redundantly to persist media failures by reconstructing the requests on reads using the redundancy. The transmitting module transmits either a request command to initiate a read operation or an acknowledgment data on completion of a write operation.
