Zusammenfassung: This article talks about VMware Quick Boot for VMware ESXi on PowerEdge Servers.
Weisungen
VMware Quick Boot is a new type of "soft" reboot mechanism introduced in vSphere 6.7. Unlike a regular host reboot operation (warm or cold), Quick Boot does not involve going through the hardware reboot process. When you initiate a Quick Boot, ESXi restarts in a way similar to normal reboot operation. The hardware, however, does not go through the normal process of reboot operations such as POST, firmware load, re-initialization of hardware resources, and reloading ACPI/SMBIOS tables.
This feature helps to speed up server management workflows which do not require a hardware reboot. For example, applying an ESXi security patch or upgrading the ESXi hypervisor does typically not require you to have the host/hardware rebooted. See vSphere Update Manage Installation, and Administration Guide for instructions on configuration/ use this feature.
Dell EMC and VMware have worked together to enable Quick Boot on the following platforms.
- PowerEdge R740
- PowerEdge R740xd
- PowerEdge R640
- PowerEdge R730
- PowerEdge R730xd
- PowerEdge R630
The following script verifies that the hardware and software configuration of a given host supports Quick Boot. Dell Technologies recommends end users to run this script manually to make sure that the configuration is compatible for Quick Boot.
