First, list all the equipment that needs to be housed in the cabinet.
For server cabinets, the primary equipment includes rack-mount servers, storage devices, and large UPS units for power supply.
For network cabinets, the planned equipment typically includes routers, firewalls, patch panels, and fiber optic enclosures.
Mixed scenarios: If you plan to install both servers and network equipment in the same cabinet, base your decision on the heaviest, hottest, and deepest core equipment. You can also opt for a hybrid cabinet configuration.
Evaluate physical specifications
Weight: Sum up the weight of all equipment. If it exceeds 500 kg, you must choose a server cabinet.
Depth: Measure the deepest point of the equipment. If the depth exceeds 600 mm, you need a server cabinet with a depth of 1000 mm or more to allow space for cabling and heat dissipation at the rear. If the equipment is generally shallow and lightweight, a network cabinet may be suitable.
Cooling: If the total power consumption of all equipment exceeds 3 kW, or if equipment density is high, choose a server cabinet with high ventilation rates and the option to install blanking panels. If power consumption is lower, a network cabinet usually suffices.
Consider power supply and installation environment
Power distribution: If you need to power multiple devices and want to monitor power consumption or remotely control outlets, configure the cabinet with a smart PDU. These are best suited for mounting on the wide vertical rails of server cabinets.
If you only need to power switches, a basic PDU is sufficient, and a network cabinet will meet your needs.
Installation environment: Server cabinets require placement in a dedicated data center room. Network cabinets can be placed in non-specialized environments, such as office areas or telecommunications closets.
Consider the future and budget
Expansion space: Reserve at least 20%–30% of space (U), power capacity, and load-bearing capacity for future needs. Server cabinets offer greater advantages for expansion.
Total cost: Consider not only the price of the cabinet itself but also the cost of accessories. Generally, server cabinets come at a higher cost. If you use it to protect core IT systems, then this investment is necessary.
