I have a quote of $400 for a half cabinet (21U) + $15/amp. If each SP30 is about 15 amps at 208v then it should come out to $225 per SP30 + $400 fixed cost.
Is that viaWest? so basically around the same cost.
It's not the same cost. Well the power cost is nice, but we also have to pay for a half cabinet while using only part of it. During the last weeks I've sent a lot of e-mail to a lot of datacenters in Europe and no datacenter is ready for bitcoin miners colocation. We need a datacenter which can supply a lot of power for small boxes. Paying for a 21U cabinet to use just a part of it is wasting money.
That is true, however i wouldn´t bother with any DC in Europe (except Iceland) as their power cost isn´t competitive on a global scale.
DCs in Iceland can typically handle a good power density, as their free air cooling is superb.
Washington State has some DCs equipped for high density, but you will not get any service there, if you are only looking for 1-2 racks. They sell corporate volume only.
Keep in mind that most DCs are older, and 6kW/rack was considered plenty.
I talked to a DC in Iceland and they gave me a price of 95 EUR per kW per month. That comes out to about the same price.
