Abstract

Described are proposed self-ejecting blades. The end-user can remotely eject the blade (using one of the many management module interfaces), walk to the server room, and simply look for the one that is no longer in its slot. This method guarantees that the blade can be found easily, is turned off, and can safely be pulled from the chassis.

Apparatus for Blade Server Self -Ejection

Finding a single problematic blade in the midst of thousands can be difficult. Currently the ability to turn on a blade information light is offered. Unfortunately there are lots of lights on the chassis, and the fact that the light is on may not necessarily mean that the blade needs to be pulled from the chassis. Additionally turning the light on does not guarantee that you have remembered to correctly power the blade off. Also turning the light on does not guarantee that other blades in the rack do not have their lights on as well. Additionally an off blade with an information light on may simply mean that it's waiting for someone has forgotten to un-set the information light in the management module.

     Proposed are self-ejecting blades. The end-user can remotely eject the blade (using one of the many management module interfaces), walk to the server room, and simply look for the one that is no longer in it's slot. This method guarantees that the blade can be found easily, is turned off, and can safely be pulled from the chassis (Figure 1).

     Add interfaces to the Management module to eject selected blades. On each blade or as part of the chassis hardware management controller (HMC) managed actuators are added that pop the blade out of the slot.
