HPE DL380 G11 8SFF X1 TM U.3 BC KIT - P48815-B21

HPE P48815-B21 DL380 Gen11 8SFF x1 TM U.3 Backplane Kit

Overview

The HPE P48815-B21 is a single-bay Tri-Mode (TM) U.3 backplane kit designed to expand drive bay capacity on HPE ProLiant DL380 Gen11 servers configured in the 8 Small Form Factor (8SFF) drive chassis. It addresses a targeted deployment need: adding one additional U.3-capable bay to a DL380 Gen11 platform without requiring a full backplane replacement. Weighing 3.78 lb, the P48815-B21 is a factory-new, genuine HPE option kit sourced through channel-direct distribution. UNSPSC classification 43211600 confirms it is categorized as computer equipment components.

Compatibility

This kit is designed specifically for the HPE ProLiant DL380 Gen11 platform in the 8SFF drive bay configuration. The Tri-Mode backplane architecture supports U.3 drives, which are capable of operating across NVMe, SAS, and SATA protocols on a single physical interface — meaning the drive bay can accommodate a range of enterprise storage drives without hardware changes when the host controller supports the respective protocol. Confirm that your DL380 Gen11's storage controller (such as an HPE Smart Array or HBA) is U.3-aware before ordering, as the backplane's Tri-Mode capability is only fully realized with a compatible controller. This kit is not compatible with DL380 Gen10 or earlier generations, nor with large form factor (LFF) chassis configurations.

Installation Notes

Installation is performed within the DL380 Gen11 server chassis and requires standard HPE ProLiant service procedures — power down, remove the access panel, and follow HPE's drive cage removal sequence for the 8SFF bay. No specialized tooling beyond standard Phillips and Torx drivers is typically required for HPE option kits of this type, though consult the DL380 Gen11 server maintenance documentation for bay-specific torque and cable routing requirements. The x1 designation indicates a single additional TM U.3 bay is added — plan drive population and controller port allocation accordingly before installation. Country of origin spans multiple regions (BR, CN, CZ, JP, MX, SG, US), reflecting standard HPE global manufacturing for option kits.
