Power consumption guidelines
The BladeCenter S system is configurable with varying numbers of some individual components. As you add components to the BladeCenter S system, the power consumption increases.
Blade servers, fan modules, SAS or SATA drives, and other components all contribute to the power footprint. A BladeCenter S system can have a minimum of two or a maximum of four power supply modules that must provide the 12-volt power for all of the components that you are including in the chassis.
| Component | Maximum Watts |
|---|---|
| Midplane | 5W |
| Media tray | 7.5W |
| Fans (four) | 240W |
| Advanced management module | 25W |
| Power module fans (two power modules) | 20W |
| I/O module | 45W |
| SAS connectivity module | 65W |
| SAS RAID controller module | 65W |
| Battery backup unit | 10W |
| Disk storage module | 120W |
| Serial pass-thru module Note Power for the | 0W |
The maximum wattage requirement for blade serves varies depending on the type of blade server installed in the BladeCenter S system. For the latest information related to power consumption and requirements for blade servers, see the IBM System x and BladeCenter Power Configurator.
