comment Place server machines in relatively humid underground room during the summer?
thanks for your answer, I have actively measuring the total power consumption of my servers using wattage meter. when idle, average power per machine is around 50w, and peak 200w, therefore around 1kw~2kw in total. In summer, I hope the total generated heat will drive down the RH%. will monitor that, and install air con if necessary.

comment Moving Gitlab and Gitolite server to another machine
if you use SQLite, this should be even easier. skip the mysql part and rsync the SQLite db file.

to be honest, this will be used in a subway train, around 4-6 cabins per train, each cabin has about 3-5 computers running linux. I am a software designer, but not too much knowledges about the network topologies. Q: is a noraml 200usd Switch like netgear one a multilayered switch?
