I've got the following gear in a small 120sqft room. While AC is supplied it's a home/office and in the summer both the central air at full go and a standup indoor portable AC on full barely keep it below 25-28c.
- 4 servers HP/IBM 4u/5u
- 1 24port switch
- 1 1300va UPS
- 1 3000va UPS
- 4 routers/wireless aps
- 4 lcd monitors
- 1 workstation
I'd done some reading when working on a clients server room and read 220v is more efficient and generates less heat. But will it make any significant difference when the real culprits being the servers get switched to 220v? I might even go down to three servers this summer to help the heat situation.
The electrician quote about 400$ to run the BX cabling and install a new breaker. I've gotta use the BX armored cable because I'm in a older condo building.
I'm also going to have to spend money to replace the UPSs with 220v units.
