Symptome
Some PCIe M.2 Solid State Drives (SSD) fail detection when installed on Multi-SSD interposer cards. This issue has been observed on a Dell Precision Workstation after the interposer card was installed in the system by the system user. Only a single SSD drive was detected.
Ursache
This issue is caused by which slot the interposer card is installed in. The Precision Tower 5810, 7810, 7910 systems are equipped with multiple PCIe slots that will accept x16 PCIe form factor cards, however some of these PCIe slots are wired as PCIe x4, not PCIe x16.
If the slot is wired as PCIe x4, then only one SSD on the interposer card will be detected.
If the slot is wired as PCIe x4, then only one SSD on the interposer card will be detected.
Lösung
Move the interposer card to a true x16 PCIe slot.
Note: PCIe SSD M.2 Interposer cards installed by Dell from the factory are installed in x16 wired PCIe slot.
