OPTIMAL STORAGE AND WORKLOAD PLACEMENT, AND ENSURING HIGH RESILIENCY IN GEO-DISTRIBUTED CLUSTER SYSTEMS

摘要

Technologies for cluster systems that are natively geo-site-aware. Such a cluster system makes use of this awareness to determine the subsets of nodes located at various geo-sites at physical configuration, to optimize workload placement based on the geo-sites, to make failover and failback decisions based on the geo-sites, and to assign voting and prune nodes for quorum management based on the geo-sites. Such capabilities result in cluster systems that are more resilient and more efficient in terms of resource usage than cluster systems without such native geo-site awareness.

1. A method performed on a cluster system comprising at least one computing device that includes at least one processor and memory, the method comprising:
automatically identifying, by the cluster system, a plurality of geo-site objects that each indicate a subset of physical resources of the cluster system that is physically located at the corresponding geo-site; placing, by the cluster system, a workload of a client on a node of a geo-site object of the plurality of geo-site objects, where the geo-site object corresponds to a geo-site at which the client is located; and placing, by the cluster system, dependent storage of the workload on another node of the geo-site object.
