Four-post racks are similar to two post racks in that they allow unrestricted airflow, easy access to IT equipment and wiring, and provide a simple, cost-effective solution. However, the four-post racks easily integrate with strip PDUs unlike the two post. Therefore, the four-post racks are an easy solution for small to medium-sized data centers where security is not a main concern.
These racks also have the option of threaded mounting holes or square mounting holes depending on the server’s requirement. Four-post racks are ideal for servers, networking equipment, and telecom equipment.
