OpenVZ Philosophy 14
Resource Management
OpenVZ Resource Management controls the amount of resources available to Virtual Private
Servers. The controlled resources include such parameters as CPU power, disk space, a set of
memory-related parameters. Resource management allows OpenVZ to:
 Effectively share available Hardware Node resources among VPSs;
 Guarantee Quality-of-Service (QoS) in accordance with a service level agreement (SLA);
 Provide performance and resource isolation and protect from denial-of-service attacks;
 Simultaneously assign and control resources for a number of Virtual Private Servers, etc.
Resource Management is much more important for OpenVZ than for a standalone computer
since computer resource utilization in an OpenVZ-based system is considerably higher than that
in a typical system.
