Abstract: Described are techniques for processing requests at a data storage system. A request is received from a client to perform an operation with respect to a first data portion stored on physical storage devices of the data storage system. The first data portion is exposed through a set of at least two data nodes each accessing a same copy of the first data portion stored on the physical storage devices. The request is received at a first of the data nodes of the set. The request is processed with respect to the first data portion using the same copy accessible to each of data nodes of the set. The physical storage devices may be configured in a RAID group and the data nodes, optionally along with a name node providing metadata, may be embedded in the data storage system and execute in a virtualized environment.
