Server Virtualization: 10 Reasons to Invest
Last Updated: 02-03-2011 , Posted: 12-03-2010
This Top 10 list of reasons to invest in server virtualization is aimed at system and virtualization administrators.
Sever virtualization: it saves money, it's green technology and it decreases the number of physical servers needed. These are just a few of the reasons why virtualization is such a hot technology topic in the IT industry. System administrators and virtualization administrators who manage those environments also consider virtualization to be a hot technology but for different reasons. Kenneth Hess explains why in this server virtualization Top 10 list on ServerWatch.
1. Common Management Interface
With server virtualization you'll find that having all your servers available in a single application is cool, but the ability to control those servers from that single interface is downright arctic. Virtualization offers access to virtual machine (VM) hardware, consoles and storage. Your entire gaggle of systems as readily available as a pocket protector full of trade show pens is almost too good to be true.
2. ILO Not Required for Server Virtualization
For the unlucky lot whose hands-on techs don't setup your Integrated Lights Out (iLO) interfaces, server virtualization removes that burden for the better. Virtualization allows you to boot a VM from a powered-off state without the need for physical access to the system. The number of saved trips into the data center is worth the most minuscule return on investment from switching to a virtual infrastructure.
3. Virtualization Provides Easy "Hardware" Changes
Changing hardware and upgrading systems is no trip to the beach. In fact, it's absolutely maddening inside even the most plush data centers where you must kneel, stretch and bend in unnatural ways to break open a case, remove old hardware and install the new pieces. And, after all that fun, your hardware might not work and you have to repeat the process -- possibly multiple times. You can upgrade memory, increase the number of CPUs and add new hard disks to a VM with a few mouse clicks. You won't need any tools, yoga lessons or trips to the chiropractor after upgrading the hardware in a VM.
