FAQs

Q: What is included in this kit?
A: An 8-bay U.3 Tri‑Mode mid‑tray backplane assembly for DL385 Gen11. Cabling and controllers are typically ordered separately unless otherwise stated.

Q: Can I use NVMe, SAS, and SATA drives together?
A: Yes, Tri‑Mode supports NVMe/SAS/SATA, but mixing is subject to controller port mapping and firmware; follow HPE configuration guidelines.

Q: Does this backplane provide x4 NVMe bandwidth per bay?
A: No. This version is wired x1 per bay. For full x4 per bay, select the x4 variant.

Q: Is it compatible with DL385 Gen10 or other servers?
A: No. It is intended for DL385 Gen11. Use the model‑specific backplane for other platforms.

Q: Do I need a specific controller?
A: A Tri‑Mode/U.3 capable controller (and matching cables) is required to enable NVMe/SAS/SATA on this backplane.
