Thanks for your replies everyone, for people following and interested:
Regarding containers: bit5ive: no hot isle, a real problem for cold climates, on cold resetarts where u would want to divert warm air to warm down units so that they can start... No real filter kontena: looks like bitmain clone, a bit more expensive than bitmain, but more flexibility for miner choice and install. Crazy high quality looking filter bitmain: hard to get any meanful answers out of them, they seem to be cUL / UL certified, therefore insurable easily.
Will check some more... any working experience with any containers please add.
characteristics of power: -25000kv, 3 phase power, we are going to drop it to 416 for the container as that seems to be the standard... -*important* (low voltage) power bumps are possible, all bitmain units seem to have the probability of temporarily lose hashboards during these events, and remedial action is to phsyically unplug, replug the units... remote reboot doesn't seem to help (anyone have a solution?)
climate: cold, very cold. Dryish, Bitmains latest units will not start colder than -2c or so (as shown in kernal log), it does an internal check on temperatures, and stops the boot up process. not sure where this probe is, but you could have a unit with a warm hash boards that u want to reboot, but rebooting it remotely could cause this check to fail and then u have need manual intervention, and then this causes a headache... No such problem with innosilicon boot up sequence.
internet: yes secure and appropriate facility: yes
