Greetings. We have about a 10x10 server room with one rack. It includes 6 switches, our firewall/appliance, our SAN, and maybe 6-8 rack servers, along with other odds and ends (couple desktops, etc.)
It's currently cooled by a Mitsubishi Mr. Slim wall-mounted AC unit. The Mr. Slim has had numerous issues over the years (coolant leak in roof-mounted unit, replaced motor/bearings, etc.). We're awaiting quotes on repair or replacement.
Does anyone have a recommendation for a reliable single-zone AC unit for a small server room ? I'm looking at the newer Mitsubishis as well as TRANE. What do you all use in your small server rooms ?
