Abstract :
A wide proliferation of distributed storage systems call for more robust and efficient systems than regular replication based storage systems. The Low density parity check (LDPC) codes have become a popular alternative to traditional Reed-Solomon (RS) erasure codes due to their low computational complexity. In this paper we propose, Spread Store- a distributed storage system based on LDPC code. Also, a brief analysis is made by examining different LDPC codes from the perspective of their efficiency and erasure handling capabilities.
