While for the most part you are going to be putting together server racks that are going to remain in the same location over their entire lifetime, there is going to come a time when you may be asked to build a mobile server system. When this happens you are likely to find that using a 4 post rack that has wheels mounted on the base.
The 4 Post Rack Is More Structurally Rigid
One of the biggest reasons that most IT techs will choose a 4 post rack over a 2 post design is that these racks are far more structurally rigid. This means that you can load them down with all of the servers and support equipment your client is going to need and they will still roll around as necessary without collapsing or falling apart, ensuring that the equipment is not going to be damaged.
If you creating a new server room and need the flexibility to add and remove equipment in a range of non-standard sizes, you may find that using a 4 post rack may be your best option. Unlike a more tradition server rack that has set sizes and mounting holes for each server, these racks are drilled to accept whatever size equipment you plan to use.
The Open Design of a 4 Post Rack Makes Installation a Breeze
With evenly space holes on each post, the 4 post rack lets you decide where you are going to mount your servers and any other equipment. Installation can be completed in just minutes using the enclosed hardware and you can leave as much or as little space between your servers for cooling air as you feel is necessary. These racks are even available with wheels on them so you can create portable servers should the need arise.
