19 inches racks refer to the standard mountable width of the server or the racks that will be placed inside that. It is the most conventional rack used in the world of servers. Since servers are kept in vast chunks of metals, adjustability is difficult.

Why should you go for 19 inches?

The Electronic Industries Alliance or EIA created the standard size of server racks. They are the ones who standardized the term “rack unit” and other terms used today.

EIA has claimed that the standardization means to rise market share, boost quality levels, and enhance customer satisfaction.

What do 19 inches refer to on a server rack?

19-inches are not the server rack width that is considered necessary. All you need at the end of the day is for your rail to be lined up with the rack’s cage nuts or threaded holes.

Server chassis whose width is less than 17.75 inches can be used instead of the 19 inch EIA standard. Larger than that measurement won’t allow you to insert the server from the front portion. Plus, your rails or shelves should be 18.31 inches apart. The front panel width is the actual panel with your server, which needs a 19 inches dimension.

Does the server width really matter?

Significant brands like Intel, Dell, HP, and IBM follow the 19 inches EIA standards on their servers. It helps them from losing their customers over any compatibility issues. Even Apple has made its new rack-mountable Mac Pro as per the latest standards.

Other than 19 inches racks, 23 inches racks are built for bigger servers. More space gives more capability to enhance performance in the data center environments.

What are the best 19 inches servers?

The best rack for you can vary as per your requirement.

• Height: It is measured by ‘rack units’, that means a 1U server is equal to 1 rack unit or 1.75 inches.
• Depth: It is the most adjustable factor compared to height and space. Its rails can adjust forward or backward.
• Space: It is to be considered first. You need to choose the server as per the area you have.
