A customer and I were talking about Parity Declustering and Distributed Sparing. We don't really understand the presence of either options in the Lustre system. It has been our understanding that past instantiations of Lustre rely entirely on the enterprise storage beneath the Lustre system in order to achieve High Availability. I.e., if one were to want RAID-6 functionality from a local Lustre node, the one would install Lustre on a storage device running RAID-6 in hardware, and if one were to want split-path failover, you'd buy (for example) two storage nodes, and rely on the storage for the failover. What are we not understanding?
