In a hot aisle/cold aisle floor design, best practices are not to mix the hot air with the cold air. I am using blanking panels, floor grommets, everything that I've learned over the years in managing data centers to get the optimal cooling from my CRAC units.
One question I have relateing to racking telco gear; specifically switches. In order to make the most effective way to cable the switches, the port connection side is at the back of the rack or hot aisle side. This means the exhaust fans are facing the front of the rack or the cold aisle side. Though most switches do not exhaust a tremendous amount of heat, in a extremely high density rack it definitely has an impact that mixes the exhaust heat into the front of the rack or cold aisle.
Has anyone else come across a solution to this and what is really an efficient way to rack telco without experiencing the air mixing yet can be easy to connect ports.
Thank you in advance.
