Virtualization, to many people, is a very hot topic when it comes to many people working in Technology. Many people see it as some new fancy thing that has been around for a few years, but it has been around for a LONG time. It is truely astounding how many people still have no idea what virtualization is, let alone having any plans to deploy it in their infrastructure.
VMware have ruled the market in this area for over the past 10-15 years, however they have a serious competitor. Whilst VMware stay put over in the blue corner, not really offering much more than in recent years other than charging their customers through the nose for their solution, over in the red corner, is Red Hat offering a solution that not only significantly outperforms VMware’s products with obscene statistics, but the TCO is also obscenely cheaper than what VMware can offer.
I have recommended VMware virtualization technologies to many customers across many continents, for many years as well. However, that has now ceased as now if a customer asks me what’s the best solution for their virtualization roadmap, I am now finding myself only ever recommending Red Hat Enterprise Virtualization or RHEV for short.
At the end of the day, its less than half the price, you get a huge amount of performance more than what VMware can offer, and realistically, you’ve just spent a huge amount of money buying your physical servers. You want to get the most out of them as you can. We all know they aren’t cheap.
This article, will walk you through installing Red Hat Enterprise Linux (RHEV)v3.0.5 and get you up and running with a two node hypervisor cluster.
For this article, I went out and bought 3 HP Proliant MicroServers, so you’ll have to forgive me for not having a huge amount of memory or CPU resources 😉
You will need 3 servers and some storage to get RHEV up and running. I have used one of the microservers for RHEV Manager, and will use the other two as my hypervisors.
I also have some spare network storage floating around as well so I will be creating a NFS Datacenter. You can also use Fibre Channel or iSCSI if that’s what you have available.
Just like VMware’s ESXi hypervisor installation, Red Hat give you RHEV-H as a like for like replacement. Just put a CD in and do a quick install. But.. Red Hat also let you use normal every day Red Hat Enterprise Linux as a hypervisor as well.
In this guide I will walk you through setting up RHEV-H. I will cover adding a RHEL managed node in a separate article.
