VMware vSphere ESXi 8.x on Dell PowerEdge Systems Installation Instructions and Important Information Guide

Prerequisite: See the System Requirements for Using Quick Boot During Remediation section in vSphere Update Manager Installation and Administration Guide. It is recommended that you carefully assess the configuration before enabling Quick Boot.

Quick Boot of an ESXi host is a setting that allows Update Manager to optimize the remediation time of hosts that undergo patch and upgrade operations. If the Quick Boot feature is enabled, Update Manager skips the hardware reboot (the BIOS or UEFI firmware reboot). As a result, the time that is spent by ESXi host in Maintenance Mode is reduced, and the risk of failures during remediation is minimized.

Quick Boot is verified and is supported with a limited set of hardware platforms, and drivers. Quick Boot is not supported on ESXi hosts that use TPM or pass-through features.
