We are living in a trend of remote System Administration and in real-time we rarely touch and feel a server that we are managing for 24×7 ( 24 Hours a Day and 7 days a Week). Although we don’t really deal with our servers physically, it is always better to know about the hardware that we have to support remotely. The Physical Server hardware awareness helps us for quick decision-making during the hardware troubleshooting.
A decade ago, when I was learning my system administration course, the most challenging task for me is imagine about how a real-time servers looks like and how those servers are different from regular PCs. I couldn’t touch and feel a real server until I joined to my first job as UNIX admin and the server is Enterprise 450 ( a real elephant in shape and weight).
Today, Sysadmin learners are lucky enough to watch the real-time servers before they actually work on it, and the courtesy and credit goes to Oracle. Below are some of the important and powerful servers from oracle which are available in market for mission critical UNIX environment.
