N12910SAS N16910SAS W12910SAS W16910SAS how many PCIe slot usable?
The N12910SAS N16910SAS W12910SAS W16910SAS have following physical slot:
Physical slot: PCIe 3.0 x 16 1slot (PCIE6/4: single at x16 (PCIE6); dual at x8 (PCIE6) / x8(PCIE4) PCIe 3.0 x 8 1slot (PCIE4) PCIe 3.0 x 4 1slot (PCIE7: shared with M.2) 3.0 x 1 1slot (PCIE5)
Due the PCIe 3.0 x 8 slot share from x 16, thus for best expandability the PCIe x 8 slot for HBA card (link HDDs) used, and able to support an additional PCIe x 8 card only.
TYPE1: (current usage) PCIe 3.0 x 16 1slot (PCIE6/4: single at x16 (PCIE6); dual at x8 (PCIE6) / x8(PCIE4) PCIe 3.0 x 8 1slot (PCIE4) (HBA card occupied) PCIe 3.0 x 4 1slot (PCIE7: shared with M.2) PCIe 3.0 x 1 1slot (PCIE5)
TYPE2: (HBA card invaild unable to detecet any HDDs) PCIe 3.0 x 16 1slot (PCIE6/4: single at x16 (PCIE6); dual at x8 (PCIE6) / x8(PCIE4) PCIe 3.0 x 8 1slot (PCIE4) PCIe 3.0 x 4 1slot (PCIE7: shared with M.2) PCIe 3.0 x 1 1slot (PCIE5)
