HPE Proliant DL380 GEN11 2U 8SFF X1 Trimode U.3 Drive Cage KIT - P48813-B21

HPE P48813-B21 ProLiant DL380 Gen11 2U 8SFF Trimode U.3 Drive Cage Kit

Overview

The P48813-B21 is a drive cage expansion kit designed for the HPE ProLiant platform, specifically targeting 2U server configurations that require additional small form factor (SFF) storage bay capacity. This kit enables Trimode U.3 operation, allowing a single physical drive slot to support NVMe, SAS, or SATA drives depending on the drive installed — a meaningful flexibility advantage in environments where storage protocols may shift as workloads evolve. If your DL380 Gen11 build is storage-constrained and you need to add up to 8 SFF bays without changing chassis, P48813-B21 is the direct solution. It ships as a factory-new, genuine HPE component, sourced through US distribution channels with no grey-market risk.

Compatibility

This kit is engineered for the HPE ProLiant DL380 Gen11 2U rack server. The 8SFF bay count and Trimode U.3 backplane architecture are specific to Gen11 mechanical and electrical standards — do not attempt to install in Gen10 or earlier DL380 variants, as connector pinouts and backplane signaling differ. Trimode U.3 support requires a compatible HBA or storage controller; verify your installed controller (such as HPE SR controllers supporting Trimode) before ordering. This cage does not add controller capacity on its own — it adds physical bays and backplane connectivity only. For broader rack server storage accessories, confirm the exact Gen11 chassis revision with your server's QuickSpecs or serial tag before purchasing.

Installation Notes

Form factor is 2U rack at 15.40 x 11.40 x 6.80 in and 3.75 lb — account for this weight when planning rail and chassis load limits, particularly in high-density storage configurations where multiple cages may be installed. Country of origin is BR/CN per distributor structured data. Installation requires standard HPE tooling consistent with ProLiant Gen11 chassis service procedures; consult the DL380 Gen11 Maintenance and Service Guide for torque specifications and cage seating verification steps.
