METHOD AND SYSTEM OF DEDUPLICATION OF ERROR CODEC IN HYPERSCALE INFRASTRUCTURE

Abstract:

The present disclosure provides methods, systems, and non-transitory computer readable media for performing data transfers with improved error encoding. The methods include receiving a request for data transfer from a source medium in the data storage system to a destination medium in the data storage system, wherein the data storage system comprises a computer cluster and a storage cluster; determining whether the source medium and the destination medium are within the storage cluster; based on the determination of whether the source medium and the destination medium are within the storage cluster, transferring the data from the source medium to the destination medium, wherein: the data is transferred without performing error correcting code check when the data is transferred within the storage cluster, and the data is transferred with an error correcting code check when the data is transferred between the computer cluster and the storage cluster.
