The Oracle Flash Accelerator F160 and F320 PCIe cards contain one PCIe controller per card, so there is one device path per card. For example, the probe-nvme-all output for an Oracle Flash Accelerator F160 card installed in CMIOU0, PCIe slot 3 is:
ok probe-nvme-all
/pci@301/pci@1/nvme@0
NVME Controller VID: 8086 SSVID: 108e SN:CVMD512100F81P6N MN: INTEL SSDPEDME016T4S FR: 8DV1RA13 NN: 1
Namespace ID:1 Size: 1.600 TB
The Oracle Flash Accelerator F640 PCIe card contains two PCIe controllers per card. There is two device paths per card, each sharing the same PCIe root complex. For example, the probe-nvme-all output for an Oracle Flash Accelerator F640 card installed in CMIOU0, PCIe slot 3 is:
ok probe-nvme-all
/pci@301/pci@1/pci@0/pci@2/nvme@0
NVME Controller VID: 8086 SSVID: 108e SN: PHLE713400SU6P4B MN: 7335943:ICDPC5ED2ORA6.4T FR: QDV1RD06 NN: 1
