Abstract
A first node receives a read request, determines a storage drive location where data corresponding to one or more logical addresses designated in the read request is stored, and requests transfer of the data at the one or more logical addresses, from the second node, when the storage drive location is the second node. The second node reads a data chunk containing the data designated by the one or more logical addresses, from one or more storage drives, determines whether to decompress the data chunk based on the size of the data chunk and the size of the one or more logical addresses, decompresses the data chunk based on the determination as to decompress the data chunk, extracts data at the one or more logical addresses, and transfers the extracted data to the first node.
