We have all heard that an average server only utilizes 8-15% of its processing power. This makes server virtualization a no-brainer. This is currently the most common form of virtualization and just makes sense. Just by saying the phrase "server consolidation" to any customer makes them think about putting some dollars back into their pocket. High availability also becomes extremely easy and affordable. Fault tolerance, (stretch) clustering, network load balancing, and scheduled maintenance can all be managed effectively from a single suite of tools. Planned downtime is now a thing of the past because loading a virtual workload onto another server takes only minutes. Take your time doing your hardware repairs because your users can still access everything they need. Through quick migration, physical to virtual transitions are a snap. Hardware failures are also not as big of a concern because your clustered VMs will automatically pick up and intelligently distribute your workloads in minutes. Of course, clustering isn't new but virtual clusters offer the flexibility and simplicity you only dreamed of. Geographically dispersed virtual clusters are also easily managed. Basically, can you say 99.99% uptime?
