4.5.2.3 Cooling Management via HPI Controls
If you decide to use your own software for cooling management, then your software can use a
virtual cooling resource and fan resources which are defined in each domain. The virtual
cooling resource can be used to read the fan speed which the automatic internal cooling
algorithm would have computed, whereas the fan resources can be used to control the fan
speeds of individual fans in a shelf. There is one fan resource for each fan in a shelf.
The entity path and the ID string of the virtual cooling resource are defined as follows.
The virtual cooling resource contains one HPI control which reflects the fan speed which the
internal cooling algorithm computes for the shelf. The definition of the control is given in the
following two tables.
