Figure E-3  Non-ideal Open Rack Configuration
Non-ideal flows should be avoided or mitigated and confirmed through thermal testing.
Figure E-4 below shows a non-ideal open rack configuration containing sub-systems with mixed 
flow directions (white arrows). This configuration shows mitigation of potential hot air 
recirculation by leaving a gap in the rack population.
