HPE ML350 GEN11 8SFF X1 U.3 TM KIT - P47217-B21

HPE P47217-B21 ML350 Gen11 8SFF U.3 Drive Tray Kit

Overview

The HPE P47217-B21 is a single U.3 drive tray kit designed for the HPE ProLiant ML350 Gen11 server configured with an 8 Small Form Factor (8SFF) backplane. If you're expanding storage capacity in an ML350 Gen11 and need an additional U.3 NVMe or tri-mode drive carrier, P47217-B21 supplies the tray mechanism required to seat and secure that drive within the SFF bay — without it, the drive physically cannot mount. This is a factory-new, genuine HPE tray kit sourced direct from distribution, not a compatible third-party substitute.

Compatibility

Designed specifically for the HPE ProLiant ML350 Gen11 tower server with the 8SFF drive bay configuration. The U.3 interface supports NVMe drives operating in U.3 tri-mode, which allows a single physical connector to handle NVMe, SAS, or SATA signaling depending on backplane negotiation — relevant if you're deploying mixed-protocol storage in a single chassis. Verify your ML350 Gen11 is configured with the 8SFF backplane before ordering; ML350 Gen11 units shipped with LFF (Large Form Factor) backplanes require a different tray. Compatibility with other ML350 generations (Gen9, Gen10) or other ProLiant tower/rack models is not confirmed by available evidence — do not assume cross-generation fit.
