HPE P48812-B21 2SFF U.3 Drive Bay Kit for ProLiant DL380 Gen11
Overview
The HPE P48812-B21 is a small form factor (2SFF) U.3 drive bay kit designed to expand the internal storage configuration of the ProLiant DL380 Gen11 server. If your DL380 Gen11 deployment requires additional U.3 NVMe or SAS/SATA drive positions beyond the base chassis configuration, this kit adds those bays without requiring a chassis swap — a direct upgrade path for storage-dense workloads such as video surveillance recording, high-capacity NVR deployments, or data-intensive compute environments. The U.3 interface supports tri-mode drive compatibility, meaning a single backplane can accept NVMe, SAS, and SATA drives depending on the controller installed — reducing the need to commit to a single drive protocol at procurement time.
Compatibility
This kit is designed for the HPE ProLiant DL380 Gen11 platform. Verify your chassis revision and existing bay configuration before ordering — the DL380 Gen11 supports multiple SFF bay configurations and this kit is specifically matched to the 2SFF U.3 expansion slot. Compatibility with DL380 Gen10 or earlier generations is not confirmed by available evidence; do not assume backward compatibility. Pair with a compatible HPE storage controller (e.g., MR or SR series Gen11 HBAs) to fully enable U.3 tri-mode operation.
Installation Notes
Installation is an internal chassis procedure requiring the server to be powered down and removed from the rack. Follow HPE's standard ESD precautions when handling internal components. The kit ships at 2.81 lb — account for this when planning rack weight budgets in high-density configurations.
