I've got a Lenovo p520 (Intel W-2133), it has these PCIe ports available:
My cards are:
Populating the PCIe slots with this configuration works (boots, both HBAs detected), though this is less then ideal as the SAS9300-8i is running at less then full bandwidth:
Populating the PCIe slots with this configuration results in the SAS9305-16e not being detected (in BIOS or OS):
Thinking it might be PCIe lane exhaustion, this configuration results in the SAS9305-16e and the xxv710s being detected properly:
I've attempted disabling OpRom through the BIOS, enabling and disabling 4G encoding, setting PCIe speed.
I am unsure of what to do next to get both of these cards detected at x8. Does anyone have any suggestions or ideas of what is going on?
