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.

Upon request from many of our Unix Folks, I am trying to present some of the most useful configuration files for Solaris OS. Full Story

Current trend of System Administration is Remote System Administration, and as a remote system administrator most of us having very less exposure to the Server hardware and their architecture.  For a system administrator it is always beneficial to know about the hardware that he is supporting remotely, this system hardware awareness helps him for quick decision making during the hardware troubleshooting. 

Here I am presenting you the server hardware diagrams ( Front View , Rear View, TOP Open Vierw) for various servers released by SUN-HARDWARE for the past one decade.

Learning VxVM administration will be much easier by understanding below three things>

1. How Veritas Volume Manager treats Operating System Native Disks into Veritas Volumes

2. What are the operations we can do in VxVM and what commands are used to perform those operations

3. What are the background services/daemons/Configuration files required to make VxVM work in normal way

We have already covered the first Learning Objective from the post  ”Veritas Volume Manager for System Adminstrators ” . Full Story
