Server Rack best practices
When setting up a server rack is it a good idea to leave some room in between servers or can you stack them on top of eachother? Also should longer servers go below shorter servers for cooling purposes? Software/Hardware used: Server Racks

Will a hot row facing a wall cause hot spots?
I am currently in the process of planning a new pod in my datacenter. To maximize space, my plan calls for a hot row which faces a wall. Will this cause hot spots, or will it act similarly to hot row containment, and actually improve flow of return air?

High humidity in the Data Center. Any advice?
We are having an issue with humidity levels of 65% in our Data Center. I know we should be below 55% but I was wondering if our level will really hurt the equipment. Do i need to replace my overhead coolers or can I live with this? Thanks

How effective are liquid-based coolant systems in processor cooling?
I've never had the chance to work with one yet; approx. by how much percent do liquid cooling systems speed up processors? Are they worth the trouble of installation? Are there more effective and/or feasible methods of cooling available?
