With a focus on good airflow, the Dell EMC PowerEdge Hard Drive Carrier ensures operation of the server and takes into account future thermal requirements. Wherever possible, paint has been omitted in order to reduce environmental pollution, for instance with stainless-steel plates at the handle. The metal housing with formed rails supports the hard drive and provides protection through maximal air circulation. The orange-coloured circle on the unlocking button indicates that it is a hot swap component.
