Rack and rack cabinets are IT equipment storage and mounting systems that improve the organization and accessibility of IT equipment in a data center. Racks are typically made of heavy duty steel and come in various sizes, depths and colors. They feature integrated side panels, center frame uprights and multiple mounting options, including shelves and drawers. Rack cabinet accessories include cable management, cooling fans, dust filters, blanking panels, PDUs and door locks to ensure that a rack is as secure as possible. These accessories ensure that the rack has enough space for the equipment and prevents network failures due to overcrowding.
