Abstract: The present invention provides a system and a method for utilizing a parity protection module to back up data on striped aggregates. Specifically, the system computes party data for data stored at a particular location of each of a plurality of constituent aggregates, and stores the parity on one of the constituent aggregates that is a parity owner for that particular location of data. In the event one of the constituent aggregates fails, new data may still be accessed by the system (the striped aggregates), both to write new data, and to read data stored on the failed aggregate. In particular, the parity protection module allows clients to read data from a failed aggregate by running a reverse parity computation, which may also be used to restore the data to the failed aggregate.

Abstract: A system and method for offloading network processes from main processors of a storage system and performing them on parallel processing modules. Embodiments of the present invention improve performance of a clustered storage system by performing certain network processes in an accelerator module of a storage system node. The accelerator module receives multi-protocol protocol data units (PDUs) from a network interface, performs protocol operations on the PDUs to form file system requests and passes the file system requests to a local D-module. If a file system request is directed to a non-local D-module in the cluster, the accelerator module repackages the request for transmission to the appropriate D-module and passes it back to network without using local D-module processing resources or passing data over the system bus.
