HP PCIe IO Accelerator Duo requirements

In addition to the IO Accelerator cooling and RAM requirements listed in the previous table, the IO Accelerator Duo requires at least:

A PCIe Gen1 x8 slot or a PCIe Gen2 x4 slot

A minimum of a full-height, half-length slot with a x8 physical connection. For systems with PCI 1.1, all eight signaling lanes must be active for full IO Accelerator Duo performance. For systems with PCIe 2.0, only four signaling lanes must be active for full performance.

NOTE: With driver version 3.1.0 and later, the driver detects in the BIOS if the PCIe slot supports a 75W power draw. If the slot supports up to 75W, the IO Accelerator device draws up to that amount of power. However, if an external power cable is used, power is only supplied by that cable.

To verify whether a slot is supplying 75W, view the system logs or use the fio-pci-checkutility.
