Hardware – DRAC -iLO

iDRAC – Integrated Dell Remote Access Controller

KVM – Keyboard Virtual Machine
Hyper-threading Technology (HT)
Hyper-threading technology is Intel implementation to improve parallelization of computing. In short, it makes a Single CPU to appear as two separate CPU to the operating system. There are some improvements as well, Intel reports there is 30% more computing power with HT compared to just single core processor.  HT was introduced in Pentium 4 and Xeon processors in Feb 2002.

Console:

A console is an application to access the server over a network. Unlike Remote desktop, with console we can see servers even when it is rebooting. It is similar to Vcenter VM console.

Manufacturers such as HP and Dell have their own consoles and are called iLO and DRAC respectively.

We need to assign IP to these Consoles and plug network cable to the server hardware to access the server via consoles.
