22 Custom Cooling Fan Options for Dell EMC PowerEdge Servers
FanSpeedOffsetl
• Using this with “get”
reports the existing
Fan Speed Offset
setting.
• Using this with “set”
allows setting the
wanted fan speed
offset value.
• The index governs
what offset is
applied and
FanSpeed…Val
variables (defined
earlier) are the
values at which the
offsets are applied.
0-Low Fan
Speed, 1-
High Fan
Speed, 2-
Medium
Fan
Speed, 3-
Max Fan
Speed,
255-None
Example with get:
racadm get
system.thermalsettings.FanSpeed
Offset
Reports current setting.
Example with set:
racadm set
system.thermalsettings.FanSpeed
Offset 1
Results in fan speed offset set to High
value (as defined in
“FanSpeedHighOffsetVal”).
MFSMaximumLimit
• Read Maximum limit
for MFS.using index
value 1.
Values
from 1 -
100;
Default –
255
(meaning
None)
Example:
racadm get
system.thermalsettings.MFSMaxim
umLimit
Reports the highest value that can be set
using MinimumFanSpeed option.
MFSMinimumLimit
•
Read Minimum limit
for MFS.
Values
from 0 -
MFSMaxim
umLimit;
Default –
255
(meaning
None)
Example:
racadm get
system.thermalsettings.MFSMinim
umLimit
Reports the lowest value that can be set
using MinimumFanSpeed option.
MinimumFanSpeed
• Allows configuring
of Minimum Fan
speed that is
wanted for the
system to operate.
• Defines the baseline
(floor) value for fan
speed, and system
enables fans to go
below this defined
fan speed value.
• This value is
%PWM value for fan
speed.
Values
from
MFSMinim
umLimit to
MFSMaxim
umLimit
When get
command
reports
255, it
means no
user
configured
offset
applied.
Example:
racadm set
system.thermalsettings.MinimumF
anSpeed 45
Forces the system minimum speed to not
go below 45% PWM (45 should be a value
between what is read from
MFSMinimumLimit to MFSMaximumLimit).
