FAQs

Q: What is the benefit of the x1 per-bay configuration?
A: x1 provides NVMe connectivity to each bay while prioritizing broad bay count and mixed media flexibility over peak per-drive throughput.

Q: Does a U.3 backplane accept SAS and SATA drives?
A: Yes. U.3 tri‑mode backplanes are designed to support SAS, SATA, and NVMe drives via the unified SFF‑8639 connector when paired with the proper controller.

Q: Are cables included with this backplane kit?
A: Installations typically require MCIO/tri‑mode cables matched to your controller and server configuration; these may be bundled in specific kits or sold separately.

Q: Is this backplane compatible with servers other than DL385 Gen11?
A: It is designed specifically for DL385 Gen11 configurations. Use the model‑specific backplane options validated for other ProLiant servers.

Q: Can I mix x1 and x4 NVMe backplanes in the same server?
A: Many configurations can mix cages of different lane widths, but not within the same cage. Always validate against the server QuickSpecs and configuration guides.
