An overview by David Davis on memory compression, new in vSphere 4.1. Memory compression helps to prevent degradation of performance when you’re running low on memory. It’s not as fast as real memory but a lot faster than swap (on disk). This article includes configuring memory compression on your vSphere virtual infrastructure.

VMware vSphere’s Distributed Resource Scheduler (DRS) is mainly used for load balancing virtual machines on a cluster. While most virtualization admins will want to run DRS in fully automated mode, there may be certain instances when you would want to enforce some conditions by setting what are known as DRS Affinity Rules. In this article, David Davis explains setting up VM to Host Affinity Rules on vSphere 4.1.

You might be thinking that floppy disks are “dead”, right? Well, you are correct that the physical floppy 3.5″ disks (or physical floppy disks of any size) are not used anymore. However, the use of virtual floppy drives is very much alive and surprisingly useful. In this article, we will show you how to use…

Virtualization is becoming more and more popular but that isn’t reason enough to do it. So why should you virtualize your your servers? Specifically, why should you use VMware Server? Most of these reasons apply not only to VMware Server but to virtualization in general. Let’s take a look at the top 5 reasons… 1….
