Hot / Cold Aisle Design

[Anonymous user]

Our company's current data center is busting out at the seams. After losing >30K dollars worth of equipment due to power and cooling issues, we have finally been given the go ahead for a redesign.

As part of the new layout I have included a 6 foot space between the rear of each rack to make up the hot aisle. Is this enough space between them? On the cold aisles I have also made a 6 foot space between each row. Management is giving me an earful saying that it is too much space. They argue that we only need 3-4 feet max between rows, in order to remove equipment from the racks. In theory, they are correct but it would be a very confined space. Any other points that I might argue in order to increase space between rows, or am I incorrect in my layout?

Any ideas / suggestions would be greatly appreciated. We currently have 19 racks of servers / switching equipment. We have a 40K Symmetra PX that is being pushed to the extreme (90%+ load on each L). We also have 2 16K Symmetra's (old school white towers) and we have 4 of the 5000RM in rack units. We are looking to buy 2 of the 80K Symmetra PX units. I have yet to find a way to convince the folks who hold the purse strings, to buy into a Silicon system, but who knows. 😃

UPDATE: I have added a PNG image of the design concept.

with regards to real estate usage, a 36" wide hot aisle and 48" cold aisle would be optimal
