Cooling recommendations
The following illustration does not represent any particular server machine type, and
is intended only to show hot and cold airflow and the arrangement of server aisles
on the raised floor.
A typical z10 BC uses chilled air, provided from under the raised floor, to cool the
system. As shown below, rows of servers must face front-to front. Chilled air is
usually provided through perforated floor panels placed in rows between the fronts
of servers (the cold aisles shown in the figure). Perforated tiles generally are not be
placed in the hot aisles. (If your particular computer room causes the temperature in
the hot aisles to exceed limits of comfort for activities like system service, you may
add as many perforated tiles as necessary to create a satisfactory comfort level.)
Heated exhaust air exits the computer room above the computing equipment.
Refer to Chapter 2, "Environmental specifications," on page 9 for specific data
regarding temperature, humidity, and gaseous and particulate contamination.
