Abstract

Asymmetric distributed replicated data storage systems and methods are described herein. The storage system includes zones that are independent, and autonomous. The zones include nodes that are independent and autonomous. The nodes include storage devices. When a data item is stored, it is partitioned into a plurality of data objects and a plurality of parity objects using erasure coding. The data objects and parity objects are spread across all nodes and zones in the storage system asymmetrically such that a first zone includes all of the data objects and no parity objects while the remaining zones include subsets of the data objects and all of the parity objects. The systems and methods provide for data resiliency while keeping the amount of storage space required relatively low.
