When consumers and businesses use energy-efficient products, they save on electricity which contributes to lower CO2 emissions and less of an impact on the environment. Consequently, we recommend our customers choose Energy Star certified products.
This paper provides a brief description of ENERGY STAR® 4.0 certification for servers and how Lenovo ThinkSystem and ThinkEdge servers are ENERGY STAR 4.0 compliant.
Change History
Changes in the May 21, 2024 update:
- Updates to the server support table - Status of Lenovo ThinkSystem and ThinkEdge support section
- List of processors not meeting ENERGY STAR 4.0 for the SR630 V3, SR650 V3, and ST650 V3
- Added the SD535 V3 server
Introduction
ENERGY STAR® is a U.S. Environmental Protection Agency voluntary program that helps business and individuals through superior energy efficiency. It’s a simple choice that makes it easier and making it easy to purchase products that save money and protect environment.
The timeline for implementation of ENERGY STAR 4.0 for server is as follows. Refer to the following page for details:
https://www.energystar.gov/products/spec/energy_star_computer_servers_version_4_0_pd
- 12 April 2023: U.S. EPA published ENERGY STAR Computer Servers Version 4.0 Final Specification for computer server.
- After August 30, 2023, certification bodies of ENERGY STAR will be instructed to stop certifying new product submittals to Version 3.0. The existing certifications to V3.0 will remain valid for the purposes of ENERGY STAR certification until January 12, 2024
- January 12 2024, ENERGY STAR Computer Servers Version 4.0 is/will be in effect. Any computer server manufactured as of January 12, 2024, must meet the Version 4.0 requirements to bear the ENERGY STAR mark. All certifications of products to the Version 3.0 specification will be invalid for purposes of ENERGY STAR and cerfification bodies (CBs) will only submit product models certified to Version 4.0 to EPA.
Key updates/Criteria comparison between ENERGY STAR 3.0 and 4.0,
- New average pass rates of active state efficiency across the subcategories range between 24% and 34%.
- Add new definitions for Storage Heavy Servers and Hyperconverged Servers.
- Remove storage and I/O from the list of characteristics to define products family.
- Enhance the power supply efficiency and power factor Refer to following chapter Table 3 and Table 4 for detail power supply efficiency and power factor requirements.
- There were small changes made to the scope, to exclude products that would never be sold without an Auxiliary Processing Accelerators (APA) such as a GPU or FPGA.
Requirements for ENERGY STAR 4.0
Topics in this section:
For other hardware design requirements, refer to ENERGY STAR Program Requirements for Computer Servers 4.0 for details.
Product family
According to ENERGY STAR Computer Servers Version 4.0 Final Specification, specific configurations within one product family with some specific attributes can be used for processing the certification, to cover hundreds of possible hardware and software configurations. However, all product configurations within a product family must meet ENERGY STAR requirements. The required data in the Version 4.0 specification must be evaluated and submitted to the Environmental Protection Agency (EPA) for certification.
- High-end performance configuration:
This product configuration is intended to represent the highest performance computing platform within the Product Family. This configuration shall include the highest processor performance per socket, as represented by the highest numerical value resulting from the multiplication of the core count by the frequency in GHz, offered for sale and capable of meeting ENERGY STAR requirements.
- Typical configuration:
A product configuration that lies between the Low-end performance and High-end performance configurations and is presentative of a deployed product with high volume sales.
- Low-end performance configuration:
This product configuration is intended to represent the lowest performance computing platform within the Product Family. This configuration shall include the lowest processor performance per socket, as represented by the lowest numerical value resulting from the multiplication of the core count by the frequency in GHz, offered for sale and capable of meeting ENERGY STAR requirements.
System configuration | Processor | Other commodity |
---|---|---|
High-end performance configuration | Highest value of core count multiplied by frequency (GHz) | The combination that represents the highest-performance computing platform within the product family |
Typical configuration | Between high-end and low-end processor, or high volume sale | A product configuration that lies between the Low-end performance and High-end performance configurations and is presentative of a deployed product with high volume sales |
Low-end performance configuration | Lowest value of core count multiplied by frequency (GHz) | The combination that represents the lowest-performance computing platform within the product family |
Active State efficiency
There is a key criterion named Active State efficiency score (EffACTIVE) for server system, shall be calculated using the equation below and greater than or equal to the minimum Active State efficiency thresholds listed in Table 2. (Refer to the detailed definition of EffCPU, EffMEMORY and EffSTORAGE).
EffACTIVE= EXP (0.65 * ln (EffCPU) + 0.30 * ln (EffMEMORY) + 0.05 * ln (EffSTORAGE)
Product Type | Minimum Eff_ACTIVE |
---|---|
One Installed Processor | |
Rack | 26.4 |
Tower | 24.4 |
Resilient | 6.6 |
Two Installed Processors | |
Rack | 30.4 |
Tower | 26.5 |
Blade or Multi-Node | 29.1 |
Resilient | 6.0 |
Greater Than Two Installed Processors | |
Rack | 31.9 |
Blade or Multi-Node | 26.8 |
Power supply requirements
Power supplies used in products eligible for ENERGY STAR 4.0 must meet the following efficiency and power factor requirements.
Power supply type | Rated output power (W) | 10% Load* | 20% Load* | 50% Load* | 100% Load* |
---|---|---|---|---|---|
Multiple output (Ac-Dc) | 750W or greater | N/A | 90% | 92% | 89% |
Multiple output (Ac-Dc) | Less than 750W | N/A | 87% (-3%) | 90% (-2%) | 87% (-2%) |
Single output (Ac-Dc) | 750W or greater | 90% (+7%) | 94% (+4%) | 96% (+2%) | 91% |
Single output (Ac-Dc) | Less than 750W | 83% | 90% | 94% | 91% |
* Number in parentheses indicates a change from ENERGY STAR V3.0
Power supply type | Rated output power (W) | 10% Load | 20% Load | 50% Load | 100% Load |
---|---|---|---|---|---|
Multiple output (Ac-Dc) | All output rating | N/A | 0.80 | 0.90 | 0.95 |
Single output (Ac-Dc) | Output rating ≦500W | N/A | 0.80 | 0.95 | 0.95 |
Output Rating > 500W and Output Rating ≤ 1,000W | 0.65 | 0.80 | 0.95 | 0.95 | |
Output rating > 1,000W | 0.80 | 0.90 | 0.95 | 0.95 |
Status of Lenovo ThinkSystem and ThinkEdge support
Lenovo ThinkSystem and ThinkEdge servers meet all the criteria for ENERGY STAR 4.0 when using the High-End Performance or Typical configurations.
For the Low-End Performance configurations, due to multi offerings for different use case through industry, some low-cost CPU SKUs with a low number of cores and/or low frequency cannot meet the minimum Active State efficiency criteria, and are therefore not ENERGY STAR 4.0 compliant. These exception SKUs are listed in the following table.
Note, even if a compliant processor SKU is installed, the server may still not be ENERGY STAR 4.0 compliant if a PSU is installed that doesn’t meet the minimum PSU efficiency and power factor requirements, as listed in the tables in the Power supply requirements section.
