Total System Power Consumption
The following tables contain minimum and maximum power consumption for the 1.1 GHz, 1.3 GHz, 1.5
GHz, and 1.7 GHz Eserver pSeries 690. Minimum power consumption is based on a configuration
consisting of a single 4 GB memory card, 1 PCI card per I/O subsystem, and 1 DASD device per I/O
subsystem.
Maximum power consumption is based on a configurations consisting of two 32 GB memory cards per
MCM module in 1.1 GHz and 1.3 GHz machines and two 64 GB memory cards per MCM module in 1.5
GHz and 1.7 GHz machines, maximum PCI cards (20 per I/O drawer), and maximum DASD (16 per I/O
drawer).
Power consumption calculations are estimates. Actual values may vary.
Calculate heat load (Btu per hour) by multiplying the power (in watts) for the configuration by a factor of
3.4.
Note: Certain system configurations only support a maximum number of I/O drawers. If a system does not
support a particular count of I/O drawers, it is indicated with ″N/A″.
