This week, we published the musings of Reg readers - more than a thousand of you - on servers, virtualization and operating systems. This inspired us to dust down a couple of papers from the Reg Library for your delectation.
The world has moved on from the whys to the hows of of server virtualization, according to Forrester Research. In this NetApp-sponsored paper three Forrester analysts run through the hypervisors, the system management tools and the savings server shops can expect. Drawing on questions posed by Forrester clients, the authors compile a list of seven questions that you should ask before you replace most of those real servers with fake ones. This is a good paper to get you started thinking about server virtualization.
This one, from APC, is for people who run data centers. The paper argues that virtualization in an existing data center, with no changes to power and cooling infrastructure, always reduces data center efficiency. That's so not cool.
APC explains how this efficiency reduction occurs, how to quantify it and how to prevent it. Lots of interesting facts, lots of diagrams and no detectable sales pitch. ®
