HPE Support in Mexico After End of Life

Removing Hardware Can Make Cooling Worse

It is genuinely counterintuitive and it is a recurring ProLiant fault. A processor or an expansion card is removed to reduce load or reclaim a licence, total heat output falls, and the chassis begins throttling or shutting down thermally. Less hardware has produced worse cooling.

Cooling Is Zoned, Not Aggregate

ProLiant chassis do not simply move a quantity of air; they move it along a defined path across specific components, and the required fan population is tied to which sockets and slots are filled. Air follows the easiest route available to it. Open a gap by removing a component and the route changes, so the remaining components may be cooled less well even though there is less to cool.

Blanks Are Functional Parts

Processor blanks, heatsink blanks and slot covers exist to preserve that path, and they look exactly like the sort of thing that can be left out. Removing a component without fitting the corresponding blank is the single most common way an estate creates this condition, and it is invariably done by somebody being helpful and reducing load.

A Configuration Change Is a Cooling Change

Any alteration to what the chassis contains carries a fan population requirement and a blanking requirement with it. ICD states both when an order changes the contents of a chassis, and supplies fans, blanks and components across ProLiant and MSA generations past HPE end of support, tested and covered for one to three years.
