To keep things simple, Quick Boot is a way of restarting ESXi without going through the physical hardware reboot process. This is the first implementation of this feature, so only a limited subset of physical hardware is supported. So, how does it work? A second ESXi image is created and updated and, when rebooting new ESXi, the image is booted directly instead of doing a full reboot. Again, the purpose here is to save time.
Currently, the following hardware platforms are supported:
- HPE ProLiant DL360 Gen10 Server
- HPE ProLiant DL360 Gen9 Server
- HPE ProLiant DL380 Gen10 Server
- HPE ProLiant DL380 Gen9 Server
- Dell R640
- Dell R630
- Dell R740
- Dell R740xd
- Dell R730
- Dell R730xd
To check whether or not your system is compatible with Quick Boot, run this command on the ESXi host from the shell: /usr/lib/vmware/loadesx/bin/loadESXCheckCompat.py.
