Abstract: The data storage system is a RAID-based data storage system in which resources are globally shared. This storage system includes the first number of disks, and the RAID mechanism is used to store data on each disk. The blocks on different disks form stripes, and at least one of the blocks on the stripe stores the parity information, wherein the width of the stripe is less than the first number. The data layout of the data storage system satisfies the following characteristics: any two physical blocks in the stripe are distributed on different disks; the data blocks distributed on each disk are the same, and the distributed parity blocks are also the same; other data in the stripe associated with any piece of disk data is evenly distributed across all the remaining disks. Normal data layout and degraded data layout can be implemented by orthogonal Latin squares.

Abstract: Systems and methods are provided for performing a remote procedure call. One method may comprise, at a client device, generating a request including setting a status field in a request header to indicate to a server processor that the request is ready, writing the request to a server memory via a RDMA write operation and fetching a response generated by the server processor from the server memory via a RDMA read operation. The method may further comprise, at a server device, checking a mode flag to determine that an operation mode is set to repeated remote fetching, retrieving the request from a server memory, processing the request to generate a response and writing the response to the server memory for the response to be fetched by a client device.

The RAID controller stores data in each set of first disks and stores parity information in multiple shared second disks by the RAID mechanism. The storage system combines the parity from different RAID volumes into one shared set and this improves the performance and reliability of the whole storage system.
