Storage management for a cluster of integrated computing systems comprising integrated resource infrastructure using storage resource agents and synchronized inter-system storage priority map

摘要

Integrated computing systems with independently managed infrastructures including compute nodes and storage nodes form a cluster. Storage resource agents manage storage resources in the cluster. The resource agents identify storage requirements associated with allocation sets for resource consumers dispatched in the cluster, communicate with each other to locate inter-system storage resources that primarily satisfy locality criteria associated with resource consumer workloads, secondarily satisfy allocation set activity criteria associated with the allocation sets, and allocate the storage resources to the resource consumers to satisfy the storage requirements. The storage resource agents may base storage assignments on data placement information from a priority map. Data may be later relocated to alternate storage resources in satisfaction of cluster-wide storage policies, priority determinations, and data access rate determinations.
