I could only tell you about what we have here in Spain, we are on the Canary
Islands, but our Co-Lo is on Madrid, 3h away on Airplane, but we have people
working near the CoLo, so it's not a problem for us.
We pay 750€/month for a 45U rack with double 16A (220v here) inputs from
thiferents UPS-Diesel-Company networks, but we could only use one of them,
because the other one it's a backup one
Nowadays we have installed on the rack:
- 1 48p 10/100/1000 managed switch
- 2 dual Opteron servers (425W PSU each server)
- 8 single Pentiun IV servers (125W PSU each server)
- 1 LTO3 Autochanger (500W PSU)
- 1 KVM (35W PSU)
- 1 KVM IP (12W PSU)
- 1 TFT Monitor (25W)
and we have not any problem with energy
I think that 15A should be enought, you could allway do the calcs yourself ...
it's easy; At full load (and any server isn't allway at full PSU load), we
have:
1x43
2x425
8x125
1x500
1x35
1x12
1x25
------------
2465 W / 220v = 11,21A
That's and aproximation calc, but it's valid
