What is 19 inches in Rack Dimensions?

It’s no secret that every modern enterprise cannot function without computers and servers for Internet access, storage, and processing of information and datum. Companies use a lot of network devices, which must be placed somewhere and provide certain conditions for its operation. For the optimal performance of electronic equipment, it is necessary to accommodate hardware somewhere. Due to its ergonomic and technical features, the regarded type of 19 inch equipment racks has been recognized as the best solution for closed server premises.

What is 19″?

19″ is the distance between the pairs of guides (mounting rails or extruders) to which the active and passive hardware is attached. The standard was introduced by EIA, the organization that is responsible for the objective collection of energy data, analysis, and economic predictions in the energy industry. According to the requirements set by the organization, the distance between the holes of the two fasteners should be 465 mm.

Benefits of 19-inch Cabinets for Housing Server Equipment

1. Efficient space utilization in data centers: Accommodate a lot of apparatus in a relatively small area due to vertical mounting inside the server furniture. For example, a standard 19″ 42u 600×600mm wiring closet with standard 19 inch rack mount dimensions occupies only 0.36 m², and more than 30 standard 1U devices can be installed in this small area.
2. High reliability and durability: Some models can withstand loads of up to 800 kg. For example, TWT cabinets of the business series allow mounting and securely fixing devices that have a standard 19″ mount. These cabinets are designed to adhere to 19 rack dimensions mm, ensuring compatibility and robustness.
3. Simplified installation process: Simplify the process of installing computing devices. One person can cope with the task in a matter of minutes, and, if necessary, disassemble the equipment. Besides, no special tools are required.
4. Access control and security: Make it possible to both limit and delimit access to certain equipment and systems, due to being equipped with doors with latches.
5. Protection against environmental factors: Allow protecting the stored devices from moisture and electromagnetic radiation, as well as from dust, dirt, and other debris. Protection against electromagnetic radiation is ensured by the installation of a metal door and a protective earthing device.
6. Excellent designs and ergonomics: There are floor-standing, wall-mounted, portable models that can be installed even on office premises if required, offering flexibility and aesthetic appeal.

Standard 19 Rack Dimensions

When designing and choosing 19-inch cabinets, it is important to consider 19U rack dimensions: height, width, and depth.

The dimensions of a 19-inch rack typically range from 600 mm to 800 mm in width. Understanding these 19 inch rack dimensions is essential as the wider the cabinet is, the more space between the side wall and the rail is left, allowing for better cable management. The free space between the rail and the cabinet wall can be used for laying and mounting cables. This effective utilization of the 19-inch rack dimensions allows for the installation of wider vertical cable managers on the side, which helps in better organization of the patch cords. Vertical cable managers are crucial for routing and organizing patch and equipment cords, ensuring that every inch of the rack is used efficiently.

The term “unit” is used to define the height of cabinets and the hardware mounted in them. One unit is equal to 4.445 cm or 1.75 inches. If the cabinet is 42u, this means that the enclosure can house a maximum of 42 1U pieces of equipment or 21 2u hardware items.

Another important parameter used to indicate overall dimensions is the depth of the cabinet. A 19-inch rack depth is indicated in millimeters and varies from 450 to 1200 mm.

How to choose 19u Rack Dimensions

Choosing the right 19-inch rack dimensions is essential for organizing and protecting your equipment. Here are six key points to consider:

1. Determine Equipment Needs. Check all the devices you plan to mount in the rack, including servers, switches, and other equipment. Ensure the total height does not exceed 19u. Understanding your equipment requirements will help you decide the correct 19u rack dimensions.
2. Standard 19 Inch Rack Dimensions. The standard width for a 19u rack is 19 inches (ca. 48 cm). The depth can vary, typically from 600 mm to 800 mm. Pick a depth that fits your equipment and allows for proper cable management. Adhering to standard 19 inch rack dimensions ensures compatibility with most hardware.
3. Load Capacity and Durability. Ensure the rack can support the weight of your equipment. Some models can handle loads up to 800 kg. Decide between floor-standing or wall-mounted racks based on your space and load requirements. High load capacity is crucial for maintaining the integrity of your 19u rack.
4. Access and Security Features. Select racks with lockable doors and removable side panels for easy access and increased security. Ensure the rack includes features for effective cable management. Secure 19u rack dimensions help in maintaining the safety of your devices.
5. Cooling and Ventilation. Proper ventilation in your 19u rack is essential for maintaining optimal equipment performance.
6. Environmental Protection. If the rack will be in harsh conditions, choose models with protection against dust, moisture, and electromagnetic interference. This will ensure the longevity and reliability of your equipment. Environmental protection in 19u rack dimensions is key to safeguarding your devices.

Nowadays, any business requires a server room. However, the process of its organization is a complicated one and should be entrusted to experienced system administrators and engineers who are well-versed in the issue. When addressing skilled staff, they will help you design the best layout depending on your needs so that avoid hardware failure.
