Blade servers—ProLiant c-Class server blades use the enclosure fans to provide cooling because
they do not have internal fans. The enclosure fans are called “virtual fans” on this page. The
virtual-fan reading represents the cooling amount that a server blade is requesting from the
enclosure. The server blade calculates the amount of cooling required by examining various
temperature sensors and calculating an appropriate fan speed. The enclosure uses information
from all of the installed server and nonserver blades to adjust the fans to provide the appropriate
enclosure cooling.
The following information is displayed for virtual fans:
◦ Location
◦ Status
◦ Speed
