For all Oracle Exadata X7, X8, X8M, X9M, and later models, use Oracle Exadata Configuration Assistant (OECA) to determine the size of each rack.

In addition to the rack height, 914 mm (36 inches) of space is required above the rack height for maintenance access, as described in Table 1-25.

The space surrounding the cabinet must not restrict the movement of cool air between the air conditioner and the front of the systems within the cabinet, or the movement of hot air coming out of the rear of the cabinet.

• Space Requirements for Racks up to Oracle Exadata X6
  All racks up to Oracle Exadata X6-2 and X6-8 use the same hardware rack, and have the same space requirements.
