If you have decided to
manage the dedicated server on your own, you must have a better knowledge of how the system works and what to do to optimize output. The three essential things that you must know are remote power control, out-of-band management and rescue mode.
Remote power control helps you turn off your server remotely. This is a key aspect of server management as it puts you in charge at all times. If your primary server develops snags, your knowledge of out of band management can help you get into the server to keep it going. Rescue mode can help in fixing the common boot errors with remote access.
