stand by computers in server room

I'm pretty sure we use Liebert here. No opinions one way or the other.

I live in the third world too, all remote controlled AC here, too. In the US, that's unheard of (at least to me.)
Most other countries make more use of using Mini-split HVAC units. Here in the US Central HVAC is more common even if it uses more energy (and you have to heat/cool everything instead of just certain rooms like you can with mini-splits, and no duct to lose the temperature in a mini split)
Quite common in Mexico as well, we are using Mirage currently.

Liebert Makes HVAC? I think ours datacenter one might be too. Never looked at it much it's in a separate room. I do know it's not a normal HVAC in the sense it does not only ducts. It uses water pipes to heat/cool the air. We do have very large Liebert NX 3 phase UPSes though. They are nice.

I'm 90% sure it they are big HVAC units. I will have to look again. We have an APC Symmetra Power distribution system for our datacenter which works really well. Even triggers the generator to cut on when the main feed loses power.

Yeah ours is very big but I don't look at it nor the UPS systems much. We have a team to handle that. Our Distribution cuts over to genny automatically and the UPS is always online (battery filtered). Sadly no one bought the web card for the UPS or power distro so it doesn't do graceful shutdowns but, it would be rare to lose multiple power companies, generators and UPS. Though it could happen.

Independent of the failure issue, I wouldn't store spare machines in the server room itself. That means unnecessary clutter, as well as danger of bumping something when moving those desktops around. Better to have a separate room for spare equipment, with a workbench and tools.
-
@Nic good point. Don't treat the server room like a storage closet!
-
I agree that that sounds really cold. You must be running the AC really hard to keep it that cold. Try inching it up, don't make a bit leap. Little bits, test the servers, inch it up some more.

Did you manage to raise the temperature? Did it reduce the condensation problems?

no actually, the remote controller is still missing, and for the computer, i think we will buy a new one because it looks like the motherboard was damaged, and the computer is 3 years old so it is not a good idea to buy a motherboard, it is better to buy a new computer
-
i have no mean to measure the condensation, i think the working servers are hot enough to be protected against humidity
-
-
My six year old actually owns a hygrometer of her own.
-
ah thank you i will check that
-
It is a small but decent investment to make for your servers.
-
Are you doing anything to monitor the internal temperatures of the servers in your server room? That is the temperature that matters most.

actually i know the temperature by the degree of the air conditioner

Actually that is exactly the mistake I was trying to help you to avoid. The AC unit can't tell you that. Airflow determines how much cooling the servers get and you can only tell how well things are working by asking the server to monitor itself and tell you the internal temperature. Nothing on the outside can tell you. It's a common mistake by new IT people in the data closet to think that keeping the air cool will keep the servers cool.

it is a good point, i should implement a monitoring software to get that info

Does your server have an out of band management software? Most do if it is Dell iDRAC if it is HP iLO. They should report temperatures from their web interface.
