Agree with this post here. Adding to this thought:
Outside of initial provisioning/firmware updates. This server should only need to reboot once a month for OS/firmware security updates and maintenance. Maybe less/more depending on your organizations security posture. OP said they’re running VM’s so I don’t understand the concern with the boot time. Once you provision the host you don’t really tinker with any setting unless your adding hardware to updating firmware/os.
If the boot time is really that big a deal, get a second host and setup replication/vmotion with your VM’s to eliminate the host boot time from affecting your uptime entirely.
Maybe it’s me, but the plates design is the only thing my eyes can focus on.
