Temperatura i vlažnost vazduha u data centru
Moraju zadovoljiti kriterijume definisane od proizvođača same IT opreme (ili od ASHRAE) – na frontu rek kabineta.

Merenje temperature u data centru
Na 5 cm od fronta IT opreme, na 3 tačke po visini reka
Najbolje je ako se vrši konstantni monitoring temperatura

Iskustva prethodnih 10 god.?
Data Centri su značajno evoluirali
Hlađenje iz duplog poda - ograničeni kapacitet i ponekad nepredvidljivost
CFD analiza bitna pri projektovanju
Budućnost – tesno sprezanje IT opreme i sistema hlađenja
