I'll be carving out a 11'x7'x9' room in an unfinished part of my basement for a computer room. The gear I will run in there will peak at about 12,000BTU. I'll install dedicated cooling and I'm thinking a mini split can do the job. The only concern is in the winter, I don't want it to get too dry. What would be the best solution for cooling year round, but controlled humidity in the winter months? This isn't an average home setup so I need something specialized for a datacenter-type environment with servers, switches, etc.

I plan to install a APC Smart-UPS SRT3000RMXLT-5KTF in a 19" rack in an unfinished portion of my basement. It will require a 20A/208V circuit (L6-20P). Local code dictates that anything in the basement must have a GFCI. I know that these units suffer heavy nuisance tripping on GFCI. I can't find an official document for this particular model that talks about its leakage current and the tripping.

Wondering what documentation might be acceptable to help get an exception on the GFCI requirement. I got a pass on a non-GFCI circuit for my infrared sauna, but the manual specifically said "don't use a GFCI circuit".
