VMware vSphere ESXi hosts and their resources are pooled together into clusters. The cluster enables dynamic allocation of resources, such as CPU, memory, and storage, to VMs. The cluster provides workload mobility and flexibility with VMware vSphere vMotion.

VMware vSphere 7.0 includes the boot mode setting of UEFI and secure boot as the default configuration. See VMware Configuration Maximums to view VMware vSphere ESXi limitations.
