Abstract
Systems, methods, and circuitries are provided for supporting distributed erasure coding in a shared file system. In one example, a method is provided to be performed by an initiator device configured to read and write data in files stored in a plurality of storage nodes that are controlled by a file management system. The method includes generating a stripe by identifying data to be stored in a storage system; dividing the data into K data segments; and performing an erasure encoding operation on the K data segments to generate a parity segment, wherein the stripe includes the K data segments and the parity segment. The method includes requesting, from the file management system, respective memory allocations in the storage devices for storing respective segments of the stripe; and transmitting, to each of the plurality of storage nodes, a respective instruction to store a respective data or parity segment in the memory allocation on the respective storage device.
