"If widely adopted, [SERT] should reduce testing burdens on the server industry and enable more meaningful and consistent comparisons among products sold in different regions of the world," said Robert Meyers, the EPA's data center product lead, in a statement.
The Energy Star for Servers program covers two-and four-socket x86 rack and tower servers. The next version will add x86 blade servers, Lange said. SERT is "hardware-neutral," he said, so it could be used to measure other types of system as well, such as RISC servers.
SPEC already developed one efficiency benchmark, SPECpower_ssj2008, but it's specific to server-side Java workloads. SERT gives a more general, "holistic" view of server efficiency, Lange said.
