Can they update firmware without rebooting?
- rbanffy 4y agoYou rarely reboot the whole computer. You can take parts of it offline for repairs and the software will route around it. There is a PC inside it running Linux whose job is managing the various subsystems up from powering up the PSU, making sure UPS batteries are charged, that cooling is working even before the CPUs are powered up and microcode is loaded.
