Enabling PCIe power override

For PCIe IO Accelerators, if you have installed any dual IO Accelerator devices, such as the HP ioDrive2

Duo, then the device might require additional power than the minimum 25 W provided by PCIe Gen2 slots
to properly function. Even if additional power is not required for your device, all dual IO Accelerator devices

that receive additional power might benefit with improved performance.
HP ioDrive2 Duo devices must have additional power to properly function. For more information on which

devices require additional power, see the HP PCIe IO Accelerator for ProLiant Servers Installation Guide.
Additional power can be provided in two ways:

External power cable—This cable ships with all dual ioMemory devices. For information on installing
this cable, see the HP PCIe IO Accelerator for ProLiant Servers Installation Guide.

NOTE:

When a power cable is used, all of the power is drawn from the cable and no power is

drawn from the PCIe slot.
