Rack Servers, of which TechMikeNY primarily sells, are often installed into – you guessed it – server racks. For the magic of a server to be installed into a rack, it must first be mounted to server rails. In this blog post, we’ll provide the types of HP & Dell static rails vs. sliding rails and we’ll clear up some common misconceptions so you can avoid ordering the incorrect rails.
One of the most common misconceptions about server rails is that they are universal between server manufacturers. They are not. This confusion is likely because rack measurements are standardized, e.g., “1U Server vs. 2U Server,” the assumption is that the rails are standardized as well (you can read more about Rack Unit measurements in our blog here).
Dell and HP manufacture rails for their server models. Not only are the rails proprietary between manufacturers, but even rails made by the same manufacturer may not be compatible with all server models of the same brand. It is always best to confirm you are getting the rail made for that exact server you are looking to rack-mount.
There are two main server rail types:
- Sliding Rails – these rails, as the name suggests, are a kit which allows you to fully extend the server out of the rack, like sliding open a desk drawer (on most kits the rails get mounted into the rack and the server "drops" into the rails in the extended position). The tremendous advantage of slide rails is the server can be kept mounted to the rack while being serviced.
- Static Rails – these rails firmly fix the server to the rack in a set position. The distinct disadvantage is that the server must be completely unmounted and removed from the rack for service. However, since static rails are usually less expensive than sliding rails, they can offer significant savings (especially for large data centers where there is a high volume of rails needed).
The good news is TechMikeNY has a large selection of server rail kits for both HP and Dell servers. And if you are ever unsure of the compatibility, our Tech’s are always available to help!

Hi Adam. Thanks for your question below. The best bet is to go with R620 STATIC rails. Static rails have more flexibility when it comes to installation since there are different points for the screws (the downside is, of course, that they are static/fixed, and you won’t be able to roll out the server for maintenance, etc.). Here is a link to R620 compatible static rails:

Good Afternoon,
Recently purchased a dell r620 server. I bought a pair of rack rails, however they are apparently too long for my server Rack.
I have a Navepoint 22U open rack, that is apparently 23.6 inches deep and apparently the rails are too long for them. I am curious as to other solutions or rails i can purchase to solve this problem. thank you in advance.
