There has been a debate lately on where to run your data center cables.  Some people prefer raised floors and running the cables under the data center while other prefer to run the cables above the racks using ladders to route the cables.  In this article we will talk about some pros and cons from both camps.

Why do some customers have their cables under the floor?  Some just inherited a building with a raised floor and had no choice.  Others had buildings with low ceilings and a raised floor was their only option.  One of the biggest problems with a raised floor and running cables under the floor is blockage of air.

Racks are an important part of the airflow system of data centers.  The cold air supplied from the air conditioning units must freely pass through rack enclosures without any interference.  Air is the main carrier of heat and moisture in the data center.  Proper management of cold and hot airstreams in the data center is crucial for maintaining acceptable levels of inlet air temperatures to the servers as recommended.

Some of the factors that can affect the performance of server fans due to the design of racks are as follows.  A typical rack enclosure consists of front and back perforated doors, railings to hold the servers, and several cables that occupy the space between the back perforated door or blind panel.  All of these components create obstructions to the airflow through the racks.
