On Grid Quorums for Erasure Coded Data

We consider the problem of designing grid quorum systems for maximum distance separable (MDS) erasure code based distributed storage systems. Quorums are used as a mechanism to maintain consistency in replication based storage systems, for which grid quorums have been shown to produce optimal load characteristics. This motivates the study of grid quorums in the context of erasure code based distributed storage systems. We show how grid quorums can be built for erasure coded data, investigate the load characteristics of these quorum systems, and demonstrate how sequential consistency is achieved even in the presence of storage node failures.

Automated summary

This study focuses on designing grid quorum systems for MDS erasure code based distributed storage systems, showing how to build these systems, investigate their load characteristics, and demonstrate achieving sequential consistency even in the presence of storage node failures.
