perrack

Perrack is a term encountered mainly in technical contexts. It is often used as a compound of per and rack to denote something measured or configured per rack in a rack-based system such as data centers or warehouses. There is no universally accepted definition, and usage varies by industry.

In warehousing and inventory management, perrack commonly refers to the quantity of items allocated to or stored on a single rack or rack unit, aiding space planning and throughput modeling. In data-center procurement and operations, perrack may describe metrics or pricing on a per-rack basis, such as power per rack, cooling per rack, or the number of devices that fit in a rack. Examples include determining the perrack density of servers or calculating perrack cost for equipment installations.

Variants and related terms include per-rack, per-rack pricing, and rack-unit concepts such as U. The term tends to be informal and contextual, lacking formal standards or definitions in major reference works. See also Data center, Warehouse, Inventory management, Rack unit.
