GB 43630-2023Minimum allowable values of energy efficiency and energy efficiency grades for tower and rack servers (English PDF)

1 Scope

GB 43630-2023 is the Chinese national standard on minimum allowable values of energy efficiency and energy efficiency grades for tower and rack servers, in the field of energy and heat transfer engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 28 December 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 January 2025. Classification: ICS 27.010, CCS F01. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the energy efficiency grades and energy efficiency limits for tower and rack servers. It also describes the corresponding test methods. This document applies to one-way or two-way general-purpose tower and rack servers (hereinafter referred to as. servers). This document does not apply to servers that only have auxiliary processing accelerators. NOTE. One-way or two-way refers to the number of central processing unit (CPU) slots in a server, which is 1 or 2.

3 Terms and definitions

For the purposes of this document, the terms and definitions defined in GB/T 9813.3, ISO/IEC 21836.2020 as well as the followings apply.

3.1 work mode A mode of which the server operating system and other software are fully loaded, and the server runs a load test.

3.2 energy efficiency of servers Under specified test conditions, the ratio of server performance standard score to energy consumption. NOTE. The energy efficiency of servers is obtained by running the benchmark tool for server energy efficiency (BenchSEE).

3.3 minimum allowable values of energy efficiency for servers The minimum energy efficiency or energy efficiency score allowed by the server under specified test conditions. NOTE. The energy efficiency score is obtained by running the testing tool for the energy efficiency of servers specified in ISO/IEC 21836.2020.

4 Technical requirements

4.1 Efficiency grades The energy efficiency of servers is classified into three levels, with Level 1 being the most efficient. For servers equipped with CPUs manufactured using a process technology of 14 nm or larger, or CPUs manufactured using non-extreme ultraviolet (EUV) lithography equipment, the energy efficiency of each level conforms to the specifications in Table

1.For servers equipped with CPUs manufactured using a process technology smaller than 14 nm, the energy efficiency of each level conforms to the specifications in Table 2.

5 Test methods

5.1 Server energy efficiency testing shall be conducted in accordance with the requirements of Annex A.

5.2 The energy efficiency of servers is calculated in the benchmark tool for server energy efficiency (BenchSEE) according to the method in Annex B.
