Dimensions of a Tonga Single-Rack Micro-Module Server Room
A Tonga Single-Rack Micro-Module Server Room typically accommodates a standard 19-inch rack with a height of 42U, depth of 1000–1200 mm, and width of 600–800 mm, plus additional space for airflow, cabling, and maintenance.
Standard Rack Dimensions
Most micro-module server rooms are designed around a single 19-inch rack, which is the industry standard for IT equipment . Key dimensions include:
- Height: Commonly 42U (73.5 inches / 1867 mm), though smaller 24U or 36U racks may be used if ceiling height is limited .
- Width: 19 inches (482 mm) between mounting rails; external cabinet width typically ranges 600–800 mm to allow for side clearance and cable management .
- Depth: 1000–1200 mm is recommended for servers with deep chassis, GPU systems, or storage arrays; shallower racks (600–800 mm) may suffice for switches and patch panels .
Micro-Module Room Footprint
A single-rack micro-module server room is compact but must allow for:
- Front and rear clearance: At least 1 meter in front and 0.6–0.8 meters behind the rack for maintenance, airflow, and cabling .
- Height clearance: Ceiling height should exceed the rack height by at least 0.3–0.5 meters to accommodate lighting, cooling ducts, and cable trays .
- Floor space: Including clearance, a typical single-rack micro-module occupies roughly 2–3 square meters (21–32 square feet) of floor area .
Additional Considerations
- Cooling: Micro-modules often integrate in-row or overhead cooling; ensure sufficient airflow around the rack .
- Power and cabling: Space for PDUs, UPS units, and cable management should be included in the footprint planning .
- Scalability: If future expansion is anticipated, consider slightly larger dimensions or modular designs that allow adding racks without major redesign . In summary, a Tonga Single-Rack Micro-Module Server Room is designed around a 42U, 19-inch rack with 1000–1200 mm depth, requiring a compact room footprint of approximately 2–3 m², with adequate front, rear, and overhead clearance for maintenance, airflow, and cabling. This ensures efficient operation, cooling, and scalability for small-scale IT deployments.
