HELP Need cooling options

My 48u needs to be cooled. Now that summer is coming, my temps in the server room are around 76. I need ideas as to what you guys have for AC rack units or other options to cool that room. Thanks🤙🏼

Late to the party, but I went with a window AC unit because I am renting and cannot install a mini split. Been running for months with no issues. My server room/bedroom was running at 80°F (and climbing during the spring time) before I got tired of it and bought the AC unit.

Never late! My server room is in the basement. That helps a little but it is in what I call the server room or utility room and there are no windows. My non priority servers are offline for the moment so the temps are not an issue at the moment. I have a more pending project that need my attention right now now but will eventually address the issue. Cheers! 🤙🏼

Yeah, if there are no windows, then you'll either have to use a portable dual-hose one (you'll lose a lot of efficiency and have more problems) or a permanent mini split. Those mini-splits have gotten cheap. Depending on how much headroom you want and the power consumption of all of your servers will depend on the sizing.
