Performance evaluation of the Mojette erasure code for fault-tolerant distributed hot data storage

Packet erasure codes are today a real alternative to repli-cation in fault tolerant distributed storage systems. In this paper, we propose the Mojette erasure code based on the Mojette transform, a formerly tomographic tool. The performance of coding and decoding are compared to the Reed-Solomon code implementations of the two open-source reference libraries namely ISA-L and Jera-sure 2.0. Results clearly show better performances for our discrete geometric code compared to the classical algebraic approaches. A gain factor up to 2 is measured in comparison with the ISA-L Intel. Those very good performances allow to deploy Mojette erasure code for hot data distributed storage and I/O intensive applications.
