What is a 19 inch rack cabinet?
May 06 , 2021The most common standard server rack width is 19 inches. Most rack-mounted equipment, especially servers, have a mounting width of 19 inches measured from one hole to another.
A 19 inch server rack cabinet is a standardized frame or enclosure for mounting multiple electronic equipment modules.The 19 inch dimension includes the edges or "ears" that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws.
19 inch server rack cabinets are ideal for 19" inch rack mount equipment such as: hubs, power strips, servers, routers, computing, audio, entertainment, telecommunications, shelf,etc.
Why 19 inches?
The standard was created by the Electronic Industries Alliance or EIA. This is the same group of people who standardized the term “rack unit” and other words used in the space today.
EIA explains that the reasons for standardization is to “increase market share, boost quality levels and elevate customer satisfaction.” Though, it should be noted that EIA has no authority over the industry, other than their highly reputable recommendation.
What does 19 inches refer to on a server rack?
To meet the 19 inch EIA standard, a server chassis width will need to be less than 17.75 inches. Any larger than this and you will not be able to insert the server through the front. Additionally, your rails or shelves needs threaded holes 18.31 inches apart.
The front panel width, which refers to the actual panel of your server, is the only dimension that needs to be 19 inches. This measurement runs from essentially the outer edge of one square hole on the rack to the outside of a perpendicular square hole.
What is 19 inch in mm?
In order to show the dimensions of a server cabinet, it is important to know that a server cabinet or wall mount rack, regardless of its width, always consists of four 19-inch profiles. 19 inch is a standard distance that is used to mount 19 inch accessories, provided with mounting profiles, in a 19 inch profile. A 19 inch profile is 19 inch wide. 19 inch is 482.6 mm.
Does server width matter?
If you have a 19 inch rack and are worried about your server not fitting it, chances are you’ll be fine. Even though the 19 inch EIA standard isn’t a requirement, major brands like Intel, Dell, HP and IBM adhere to the standards on their servers.
Still, some servers are built bigger. In addition to 19 inch racks, you might come across 23 inch racks that are built for 23 inch servers. More space means more capability to increase performance so these are mostly tailored for data center environments.
Other than that, there isn’t much to look out for in terms of server width. Dimensions like height and depth can vary much more than width, so it’s relieving to at least one standard for mounting.
What are the best 19 inch server racks?
The best server rack for you depends on several factors:
- How much depth do you need?
- How much height do you need?
- How much space do you have?
Height is measured by ‘rack unit’, so a 1U server would be 1 rack unit or 1.75 inches. A simple way to gauge how much space you will need is to add up how many total rack units your equipment takes up, and then add a bit more space for expansion or accessories.
Depth is relatively adjustable especially compared to height and width. This is because rails can adjust depth frontwards and backwards. Basically, as long as no equipment is over the capacity of the racks mounting depth, you should be able to find a rail that will be compatible.
Space limitations might be the first thing you need consider.
- The smallest racks you will find can fit on or under a desk, be mounted on a wall or ceiling, or turn a single server into a computer-like tower.
- Average sized racks will be around 42U in height, have 4 posts and could fit in a medium sized closet. These are typically used for businesses or schools that need a centralized location to transfer data.
- Big data center racks won’t be too much taller than those mentioned previously, but might have more depth, room for fans, or just features in general. For instance, our data Center Rack starts with a height of 42U or 48U or 52U, but has a very high load capacity, locks, is designed to combat airflow circulation and has a significant amount of depth.
How do I easily determine which size of rack I need?
By making the right planning and knowing which 19 inch accessories and other devices will be mounted in a 19 inch rack, the height and depth can be determined. The width depends on personal preference and the available space. By using the height, width and depth filters on our website, it is easy to determine the correct size of a 19 inch rack or wall mount rack.
