Figure 5. Server airflow performance curves.
These curves show how the airflow through a server, shown on the horizontal axis, is reduced by
the presence of a resistance, represented as a static pressure on the vertical axis.
Notice that both server airflow curves (Figure 5) and perforation flow test curves (Figure 4) use the
same units on both axes. To observe the effects of perforated door resistance on server airflow,
Figure 6 plots these two data sets on the same graph and scales them to a cabinet fully populated
with blade servers. The airflow values from the 20-inch square duct sample tests were scaled to the
area of the perforation pattern for a 600mm wide, 42 RU tall cabinet door (1,200 in
2
). The 9 RU
server airflow values were multiplied by four – the number of servers that can be installed at once
in that same type of cabinet.
