Hey attagirl, are you looking at a specific area of datacenter practices? I have worked in so many different datacenters that have so many differences. Unfortunately, they all seem to have their plusses and minuses (except for one colocation center that I wont mention, ok, maybe 2 now).
Let me know which practices you are referring to and I will definitely have some examples of what we had working for us and what did not work out so well. A lot of things that we had that did not work out so well could not be remedied after the initial commissioning.
