These performance ratings apply to desktop servers, rack-mountable servers, individual blade servers, chassis containing multiple blade servers, and supercomputers intended to be supplied by a branch circuit of 600 volts ac or less.

The servers covered by this Test Method shall be provided with at least one CPU and at least one hard disk drive or solid state drive, support an operating system, and be capable of being booted from a memory stick.

These requirements are intended to be a hardware performance efficiency metric and not an application performance metric.

These requirements do not cover servers that are provided with a means for direct connection to a DC power supply.

For this Test Method, server performance is evaluated using standardized server performance software.
