When choosing a suitable RackMount Network Cabinet, the following points should be considered:
Capacity planning
Equipment quantity: Count the number of servers, switches, routers and other equipment that need to be installed, estimate the required cabinet space, and reserve 30% -50% redundant space to meet future expansion needs.
Size specifications: Select the cabinet according to the equipment size, commonly a 19 inch standard cabinet, with a depth of 600mm, 800mm, 1000mm, etc., and a height in “U” units, with various specifications such as 6U, 9U, 12U, 42U, etc. Small networks can choose 6U-12U, medium networks can choose 18U-24U, and large data centers can choose 42U or above.
performance index
Load capacity: Calculate the total weight of the equipment and consider a 20% -30% margin to select the rack load capacity. For example, if the total weight of the equipment is 300 kilograms, a cabinet with a load-bearing capacity of 360-390 kilograms should be selected.
Heat dissipation performance: Considering the ventilation hole area, fan configuration, etc., the ventilation hole area should account for more than 30% -50% of the total cabinet area. High density equipment requires more fans or liquid cooling configurations.
Functional characteristics
Cable management: Priority should be given to selecting complete cable management devices such as line connectors and cable management rings, as well as cabinets with cable entrances and exits at the top, bottom, or sides for easy wiring and maintenance.
Security protection: Check whether the cabinet has safety functions such as door locks, grounding devices, and overcurrent protection to protect equipment and personnel safety.
Other factors
Appearance and Material: Materials typically include cold-rolled steel plates and stainless steel, with cold-rolled steel plates offering high cost-effectiveness and stainless steel being corrosion-resistant. Choose the appearance color and style according to the computer room environment, commonly including black and gray.
