Changes

OpenVZ technology scales up pretty well - we've tested it on machines up to 8 CPU and up to 64 GB of RAM. Besides, a single container could be scaled up from taking a little fraction of available resources up to all resources available dynamically - you do not even have to restart the container.

For existing hardware, OpenVZ allows to utilize its processing power better by improving average load from 3-5% to at least 30-50%, while still providing ability to handle peak loads. To decrease complexity, OpenVZ provides standardized and centralized server management, logically decoupled from actual hardware. And when its time to buy new servers, you can now use few more powerful servers instead of many little ones — with added benefits of better reliability, better peak performance and typically longer lifespan.
