Environment:
v Air temperature:
– Server on: 5°C to 40°C (41°F to
104°F); altitude: 0 to 950 m (0 to
3116 ft). Derate maximum
temperature by 1°C for every 175
m (574 ft) increase in elevation to
a maximum of 3050 m (10004 ft) at
an ambient temperature of 5°C to
28°C (41°F to 82°F)
Notes:
1. microprocessor E5-2690:
temperature: 5°C to 35°C (41°F
to 95°F); altitude: 0 to 950 m (0
to 3116 ft)
2. GPGPU node: temperature:
5°C to 35°C (41°F to 95°F);
altitude: 0 to 950 m (0 to 3116
ft)
3. Intel Xeon Phi 7120P:
temperature: 5°C to 27°C (41°F
to 80.6°F); altitude: 0 to 304.8
m (0 to 1000 ft)
– Server off: 5°C to 45°C (41°F to
113°F); maximum altitude: 0 to
3050 m (10004 ft)
– Storage (non-operating): 1°C to
60°C (33.8°F to 140°F); altitude: 0
to 3050 m (0 to 10004 ft).
– Shipment (non-operating): -40°C to
60°C (-40°F to 140°F); altitude: 0
to 10700 m (0 to 35105 ft).
Environment (continued):
v Humidity:
– Server on: non-condensing: -12°C
dew point (10.4°F), 8% to 85%;
maximum dew point: 24°C (75°F);
maximum rate of change: 5°C/hr
(41°F/hr) for tape drive and
microprocessor models from 115 W to
130 W and 135 W, 20°C/hr (68°F/hr)
for HDDs
– Server off: 8% to 85%; maximum dew
point: 27°C (80.6°F); maximum rate of
change: 5 °C/hr for microprocessor
models from 60 W to 95 W
– Storage (non-operating): 5% to 80%;
maximum dew point: 29°C (84.2°F)
– Shipment (non-operating): 5% to
100%; maximum dew point: 29°C
(84.2°F)
v Particulate contamination:
Attention:
– Design to ASHRAE Class A3,
temperature: 36°C to 40°C (96.8°F to
104°F) with relaxed support:
- Support cloud such as workload
with no performance degradation
acceptable (turbo-off)
- Under no circumstance, can any
combination of worst case
workload and configuration result in
system shutdown or design
exposure at 40°C
- The worst case workload (such as
Linpack,Turbo-On) may have
performance degradation
– Airborne particulates and reactive
gases acting alone or in combination
with other environmental factors such
as humidity or temperature might
pose a risk to the server. For
information about the limits for
particulates and gases, see
"Particulate contamination" on page
369.
