Automatic space sharing of disaggregated storage of a storage pod by multiple nodes of a distributed storage system
Abstract
Systems and methods are provided for implementation and use of disaggregated storage by a distributed storage system. In various examples described herein, the association of blocks of storage space within a storage pod with a given dynamically extensible file system (DEFS) may be in large chunks of one or more gigabytes (GB), which may be referred to herein as “allocation areas” (AAs) that each include multiple RAID stripes. The use of large, multi-GB chunks, as the unit of space allocation/assignment to DEFSs of a distributed storage system facilitates ease of management and independence of write allocation. The use of AAs described herein further allows disk space to be used more fluidly across individual (nodes) storage systems of a distributed storage system (cluster of nodes working together), thereby eliminating silos of storage; and processing resource (e.g., CPU) load may be distributed across the cluster.
