Data Center Server Cooling

Twelve fans cool the Data Center server. The fans are all redundant, hot-swappable, and
interchangeable. Eight fans cool the eight DIMMs and two processors. Four fans cool the hard-disk
drives and the PCI riser board. The fans cool three zones in the server. Fans 1 through 4 cool Zone
1, fans 5 through 8 cool Zone 2, and fans 9 through 12 cool Zone 3. Each zone can run with
one fan failure. The other fans in the zone increase speed to compensate for the fan failure. The
fans are N+1 per zone, meaning that the server has 12 fans, but can operate with 9 fans running
(one fan failure per zone). See
zones.
The power supplies have built-in fans and are not controlled by the Baseboard Management
Controller (BMC).
