For cPanel & WHM 11.46

Overview

Before you install cPanel & WHM or cPanel DNSONLY, make certain that your server's hardware meets all of the minimum requirements for new installations.

Remember:

 64-bit operating systems use more RAM than 32-bit systems.

 

How to choose a server

When you choose a server, you should consider the following questions:

  • How many sites do you plan to host?
    For example, if your server will host a large number of websites, which will each have associated email addresses and databases, the server will require more processing power, disk space, and RAM.
     
  • What kind of web hosting you plan to do? 
    While cPanel & WHM will run on the minimum requirements below, the server will need more processing power, disk space, and RAM if you plan to host videos, music, or high-volume applications like forums.
