Recommended Front-to-Front Hardware Placement on Raised Floor and Open Return Environment
Recommended Raised Floor Layout for Optimum Cooling and Airflow with Open Return Environment
| Cabinet alignment | Teradata hardware cabinets are designed to take in conditioned supply air or chilled air in the front, pass it over the internal heat dissipating components, and exhaust it from the rear. All hardware cabinets must be installed front-to-front (rear-to-rear). |
| Cold aisle width |
A minimum distance of 1.2 m (4 ft)—or two floor tiles—is required in the cold aisles
, where the fronts of two rows of cabinets face each other. Perforated floor panels or floor grills must fill the cold aisles. To meet the cold air delivery requirements for a Teradata system, wider aisle width in cold aisles may be necessary to accommodate more perforated floor panels or floor grills. All of the following must be considered in determining how to meet the environmental specifications, specifically the recommended temperature and relative humidity ranges:

| BYNET cabinet placement | BYNET cabinets should be placed in the center to minimize cable lengths from node cabinets to BYNET cabinets. Leave space for additional BYNET cabinets to allow room for future growth. |
