Minimum System Requirements
HUBzero (RedHat) installations require one or more dedicated hosts running RedHat or CentOS version 6.
A typical starter HUBzero installation might consist of a single physical server with dual 64-bit quad-core CPUs, 24 Gigabytes of RAM and a terabyte of disk.
Production systems should try to not limit hardware resources, HUBzero is designed to run on systems with many CPU cores and lots of RAM. If you are looking for a system to run a small site with limited physical or virtual resources this is probably not the system for you. However, for demonstration or development purposes we often create VM images with less than a gigabyte of RAM and 5 gigabytes of disk. While fully functional, these virtual machines would only be suitable for a single user doing development or testing.
This document and the installation and maintenance of a HUBzero system has a target audience of experienced Linux administrators (preferably experienced with RedHat or CentOS distributions).
