Server Drive Backplanes — SAS, SATA & NVMe

Replacement backplane boards for Dell, HP, and Supermicro servers

About Server Backplanes

The drive backplane is the circuit board that connects all hot-swap drive bays to the server's storage controller and power distribution. When a backplane fails, some or all drive bays stop detecting disks — even though the drives themselves are healthy. We carry replacement backplanes for Dell PowerEdge, HP ProLiant, Lenovo ThinkSystem, and Supermicro platforms.

Backplanes are model-specific and must match your server's exact chassis configuration — the number of bays (8-bay, 16-bay, 24-bay), form factor (2.5" SFF or 3.5" LFF), and interface (SAS/SATA, NVMe, or universal). Some servers also have separate rear backplanes for 2-bay SSD configurations behind the CPU area.

Common Backplane Replacements

Dell R740xd 24× 2.5" SAS/SATA (0XTHGT) — high-density SFF configuration
Dell R740 4× 3.5" NVMe (0WKYR0) — NVMe-only rear backplane
HP DL380 Gen10 8× SFF (876566-001) — ProLiant standard SFF backplane
HP DL380 Gen10 24× SFF (882566-001) — 24-bay box 1/2/3 backplane kit
Supermicro BPN-SAS3-846EL1 (24× 3.5") — SAS3 expander backplane for CSE-846

Diagnosing a failed backplane? Symptoms include drives showing "missing" in RAID controller, intermittent drive drops across multiple bays, or SAS link errors in the controller log. Contact us with your server model and service tag for the correct replacement part.

Frequently Asked Questions

How do I know if my server backplane has failed?

Common symptoms include multiple drives disappearing from the RAID controller simultaneously, drives in specific bay ranges not being detected (e.g., bays 0-7 down while 8-15 work), SAS/SATA link errors in the storage controller log, and drives that work in other bays but fail in specific slots. A failed backplane typically affects a group of adjacent bays rather than a single drive.

Can I upgrade a SAS backplane to NVMe?

Not directly. SAS and NVMe backplanes have different connectors and signal traces. SAS uses SFF-8643 Mini-SAS HD connectors to the RAID controller, while NVMe uses PCIe SlimSAS or OCuLink connectors that route directly to the CPU's PCIe lanes. You would need a different backplane model, compatible drive cables, and potentially BIOS/firmware updates.

Are Dell and HP backplanes interchangeable?

No. Server backplanes are proprietary to each manufacturer and server model. A Dell R740 backplane will not physically fit or electrically work in an HP DL380. Even within the same manufacturer, backplanes differ between server generations (e.g., R740 vs R750). Always match the exact server model and configuration.
