What to Consider in a Data Center

It's not only the selection of the appropriate type of server racks and cable that you purchase, but the management of the cabling, power, and heat generation that are very important.


CABLES


Cables can be fed into the racks from above (ceiling) or below (floor) and organized with vertical or horizontal cable managers inside or outside the racks. Depending on the type, number, weight, diameter, etc., cable guides must be chosen to supply the optimal solution. This depends on whether you have copper cables (Cat 5, 5e, 6. 6A, 7) and the specific manufacturer. Fiber optic cables vary if they are duplex jumper or multi-fiber cables (MTP) and by manufacturer. We have supplied various inside rack cable management solutions including patch panels, managers with fingers, loops, rings, and outside rack solutions with ladder racks, cable trays, cable runway, etc.


POWER


There are many levels of power units (usually 15, 20, or 30 Amp) available to supply power to the switches and servers mounted in the racks. These units vary from basic multi-outlet power strips without breaker or switch to mutifuction units including Amp meters, temperature, and moisture sensors. Some units can be accessed from a remote office or home on the Internet.


HEAT CONTROL


Server rack cooling in the datacenter rack space depends on the number of switches and servers, as well as the arrangement of the rackmount server cabinet and cables. Too many copper cables in the floor can block the free flow of cooling air. The size and layout of fans and blowers installed in the racks affects the efficiency of cooling. The use of cold aisle/hot aisle cabinet arrangement to keep the hot air from mixing with the cold air can help the data center run much more efficiently. Details such as the watts/rack and the BTU’S to be handled are important in the accurate design of a computer center so that sufficient cooling is supplied.
