I had a recent interaction with a customer regarding how often to "reboot" Sun servers. There is no official policy at Sun regarding rebooting - mainly because we sell enterprise class machines. The intent of an enterprise class machine is to stay up at all cost. Our enterprise class servers have the ability to add and remove memory, IO, and CPU without a reboot. I know it is common practice to reboot "windows" based machines on a regular schedule, but this simply does NOT apply to Enterprise class Sun servers.
For sake of discussion, I will post what I think our server reboot policy should entail.
Purposed Sun Server Reboot Policy:
"Only reboot Sun servers when installing SW or HW that requires a
reboot. It is not necessary to reboot servers on a regular schedule
like Windows servers."
