Run your system for a while with softupdates off in a production mode environment. If it is fairly stable and you don't have any crashes, but turn on softupdates. With softupdates on, I would definitely recommend having the system on a UPS. > > 2) I'm considering buying doubling (or tripling) the RAM in my server and > was wondering if there are any extra steps other than the actual hardware > install that I needed to do? > None. Just plug in the extra memory and boot the system. The system BIOS may complain after the first powerup to let you know that something changed in the system, configuration.
