Racks are a common way to structurally organize network equipment and are typically key to understanding how a network works within a location.The rack model represents either a two or four post equipment rack in which devices can be installed. Each rack must be assigned to a site, and may optionally be assigned to a location within that site. Racks can also be organized by user-defined functional roles known as Rack Roles.The name and facility ID of each rack within a location must be unique.
Rack height is measured in rack units(U). Racks are commonly between 42U and 48U tall, Palpabl NMS allows you to define racks of arbitrary height. A toggle is provided to indicate whether rack units are in ascending (from the ground up) or descending order.Each rack is assigned a name and (optionally) a seperate facility ID. This is designed to allow you to indicate what space in a data center has been leased for this rack, specifically in the event you have equipment in a data center you do not own.
Users can reserve specific units with a rack for future use. An arbitrary set of units within a rack can be associated with a single reservation, but reservations cannot span multiple racks. A description is required for each reservation, reservations may optionally be associated with a specific tenant.
