Frequently Asked Engineering Questions (FAQ)
How does liquid cooling impact datacenter PUE?
Direct-to-chip liquid cooling reduces chiller energy, lowering typical PUE from 1.35 down to 1.10–1.15 and cutting OPEX by up to 20%.
What cooling capacity is needed per 100kW IT load?
100 kW of continuous IT consumption generates approximately 341,214 BTU/hr, requiring ~28.4 Tons of dedicated refrigeration.
How does power cost influence compute siting?
At $0.06/kWh vs $0.18/kWh, annual electricity for an 8-node cluster drops by over $60,000, making geographic colocation critical.
