* Unified Erasure Coding interface for common storage workloads.
* Pluggable Erasure Code backends - As of v0.9.10, liberasurecode supports 'Jerasure' (Reed-Solomon, Cauchy), 'ISA-L' (Intel Storage Acceleration Library), 'Flat XOR HD' backends. A template 'NULL' backend is implemented to help future backend writers.
* Pluggable Erasure Code backends - As of v1.0-rc1, liberasurecode supports 'Jerasure' (Reed-Solomon, Cauchy), 'ISA-L' (Intel Storage Acceleration Library), 'Flat XOR HD' backends. A template 'NULL' backend is implemented to help future backend writers.
* True 'plugin' architecture - liberasurecode uses Dynamically Loaded (DL) libraries to realize a true 'plugin' architecture. This also allows one to build liberasurecode indepdendent of the Erasure Code backend libraries.
