Abstract
In a computer-implemented method for upgrading a fault tolerant hyper-converged infrastructure in an environment with no additional physical infrastructure, a workload domain having a plurality of hosts is chosen for an upgrade. One or more conflict groups are calculated for each host, and a physical host in the workload domain is selected. A number and a size of one or more nested hosts is determined and a different nested host is created in a management cluster for each of the one more conflict groups in the physical host. A communication network provides communication between a virtual machine (VM) on the different nested host and a VM in the physical host. The physical host is put into a maintenance mode, upgraded, and then returned from the maintenance mode to an operational mode.
