Cluster capacity management for hyper converged infrastructure updates

Abstract

Disclosed are various implementations of cluster capacity management for infrastructure updates. In some examples, cluster hosts for a cluster can be scheduled for an update. A datacenter level workload can invoke an enter cluster maintenance mode component of a datacenter level resource scheduler by identifying a specified cluster of a datacenter. The datacenter level workload can receive an add host command to add a host for the host level update. Once the host level update is performed on hosts of the specified cluster, the datacenter level workload invokes an exit cluster maintenance mode component and implements a cluster scaling decision.
