Appendix D Environment requirements
About environment requirements
The operating temperature requirements for the server vary depending on the server model and
hardware configuration. When the general and component-based requirements conflict, use the
component-based requirement.
Be aware that the actual maximum operating temperature of the server might be lower than what is
stated because of poor site cooling performance. In a real data center, the server cooling
performance might decrease because of adverse external factors, including poor cabinet cooling
performance, high power density inside the cabinet, or insufficient spacing between devices.
General environment requirements
Item Specifications
Operating temperature
Minimum: 5°C (41°F)
Maximum: Varies depending on the power consumed by the processors
and presence of expansion modules. For more information, see "Operating
temperatur
e requirements."
Storage temperature –40°C to +70°C (–40°F to +158°F)
Operating humidity 8% to 90%, noncondensing
Storage humidity 5% to 90%, noncondensing
Operating altitude
–60 m to +3000 m (–196.85 ft to +9842.52 ft)
The allowed maximum temperature decreases by 0.33 °C (32.59°F) as the
altitude increases by 100 m (328.08 ft) from 900 m (2952.76 ft)
Storage altitude –60 m to +5000 m (–196.85 ft to +16404.20 ft)
Operating temperature requirements
General guidelines
You must install six fans if you are using GPU module other than GPU-M2000 and GPU-M4000-1-X.
Performance of the following hardware components might degrade if one fan fails or is absent:
• Processors 8180, 8180M, 8168, 6154, 6146, 6144, 6254, 6244, and 6240Y.
• GPU modules.
• SATA M.2 SSDs.
• DCPMMs.
8SFF server with an 8SFF drive configuration
Use Table 24 to determine the maximum operating temperature of the 8SFF server that uses an
8SFF drive configuration. A maximum server operating temperature applies if the server contains
any options in its matching hardware option list.
