Rack Hygiene – Stop the Madness!

Rack Hygiene – Stop the Madness!

We’ve all heard of personal hygiene, and perhaps you’ve heard of mental hygiene, but what about rack hygiene? Please don’t look this up in a dictionary it will only confuse you. The word hygiene is now associated with data center cabinets or racks; which is a good thing. Why? Because the word hygiene makes people think of practices that maintain health and prevents disease. The word cleanliness also comes to mind. We all want clean bodies and minds. What about your data center racks?

Think about it this way… What happens to your mental state when you must make a cable change and the cable management system looks like a bowl of spaghetti? How’s your mental health now? Is it possible that your thoughts are moving to the dark side, unclean? Would you like to meet the guy in purchasing that saved the company $200.00 per cabinet who has no clue about the time lost in network cable mining?

Stop the madness! Rack hygiene is a must for every data center. Saving a few dollars on cabinets without cable management systems is nothing short of crazy.

The time wasted on unmanaged cable during the life of the cabinets will easily outweigh the additional costs for cable management.

What we’ve learned over the years is that asking technicians to mastermind a cable management program without the proper tools is like going into battle with a slingshot instead of a rifle.

My mom use to say in her lilting voice, “A place for everything and everything in its place.” Mom was borrowing an expression that came from the 1800s that has been attributed to many sources. My favorite is the quote from Masterman Ready, or the Wreck of the Pacific in 1842 that uses the expression in a nautical context “In a well-conducted man-of-war every thing is in its place, and there is a place for every thing”.

Boats don’t have much room, so its imperative to stow everything is such a way that it can be easily found and ready for use.

The same can be said for cabinets, there is no room for clutter. A properly organized cabinet goes a long way in new equipment deployment, as well as tracking down outages.

The point we want to make is that rack hygiene and cable management begins during the purchasing phase of the racks and the cabinets. Not all cable management systems are created equal, nor for the same purpose. Here are some important variables to consider:

• Vertical cable managers
• Horizontal cabling systems
• Backbone cable installations
• Copper
• Fiber
• Maintenance holes
• Bonding & grounding
• Support facilities such as raceways, cable trays holes coring, slot and sleeves
• Fastener types
• Wireless systems

Take the time to design a cabinet that makes cable hygiene easy. Without it your technician’s mental health will be anything but clean!

The Truth Behind Data Center Airflow Management: It’s Complicated

The Truth Behind Data Center Airflow Management: It’s Complicated

Does hot air rise? The answer of course is “yes”.

Does hot air fall? The answer is yes again.

What about sideways? Yes!

Heat can move up, down, or sideways, depending on the situation. The idea that hot air has an inherent desire to flow up is a misconception that we in the data center airflow management business would like to see dissipate.

Temperature difference is the major factor with regards to the direction and rate of heat transfer. Because air tends to move towards thermal equilibrium, it is important to maintain physical separation of hot and cold air in data centers; the need for hot and cold air separation was the reason that the data center containment industry came into existence. The laws of thermodynamics state that air moves from areas of higher temperature towards areas of lower temperature. Air is a fluid that accounts for both density and buoyancy. When air is heated the molecules move around faster, which causes it to expand, and as it expands its density becomes lower. The warmer, lower density air will rise above the denser, cooler air.

Pressure is another determining factor when looking at air movement. The flow of air from areas of high pressure to areas of low pressure is an embodiment of Newton’s third law. Equilibrium is what also drives movement between areas of differing pressure, so uninhibited air will continuously move from high to low pressure until equilibrium is reached. This movement towards equilibrium is also known as expansion.

Principles of air movement:
1) Heat Transfer:
a. Conduction: Air flows from a higher temperature region to a lower temperature between mediums
that make physical contact.
b. Convection: Heat transfer due to the movement of a fluid; can be free/natural, or forced.
2) Air flows from a higher pressure to a lower pressure

What does this have to do with data center airflow management?

The data center containment industry has been inundated with graphs depicting airflow, most of which show large, sweeping lines indicating the flow of air. In most cases, the airflow depicted is a result of a mechanical device, usually a fan. The data presented by these graphs tends to lead one to believe that mechanically induced airflow will sufficiently separate hot exhaust air from cold intake air. In real-world scenarios, air curtains are inefficient and ineffective.

Modern mechanical air conditioning systems rely on four sided duct systems to deliver supply air to the source of the heat load, and the return is moved by the same means. This is the only way to ensure the separation of supply and return airflow. Systems administrators and building managers should be dubious of airflow management systems that require an increase in energy to accomplish air separation. Instead, it is best to apply the simplest principles of airflow when designing a system aimed at full separation of supply and return airflow.
