HP FC1142SR (QLogic) PCI Express Speed only 2.5 Gbps?

Hi,

when looking with SANsurfer at a HP FC1142SR FC Adapter on a DL380G6 with Windows Server 2008 x64 it reports that the MAX Bus Speed of the PCIe 4x Slot is 2.5Gbps.

Isn't this supposed to be more than just 2.5Gbps? As far as I know even PCIe 1.0 carries 250MB/s per lane in each direction so I'm wondering why it only displays 2.5Gbps.

Any ideas why this might be the case or what I'm missing here?

Thanks
Michael
