FAQs

Q: Can this cage be used alongside other front cages?
A: Yes, it is intended for the front tertiary position and can complement existing primary/secondary cages subject to chassis configuration.

Q: Does it support full x4 NVMe per drive?
A: Yes, it is wired x4 per bay; actual performance depends on the attached Tri‑Mode controller and PCIe topology.

Q: Is mixing NVMe with SAS allowed?
A: Tri‑Mode enables both, but mixing depends on port mapping and firmware. Consult configuration guidance.
