Dell 403-BBYO Boss x16 M.2 Sata Controller Card

The Dell 403-BBYO is a modular controller card that lets you add M.2 SATA storage to select PowerEdge servers through a PCI Express x8 slot. By moving drives to the server interior, you free up front drive bays and create a clean, cable-light configuration that improves airflow and serviceability.

Once installed, the card manages one or more M.2 SATA drives and supports RAID, so you can set up mirrored boot volumes for redundancy or stripe drives for extra performance. The 0.11-kilogram build is easy to handle, making swaps or upgrades straightforward even in crowded racks.

Compatibility is tuned for Dell PowerEdge platforms such as the Mx740c, Mx750c, R450, and Xr11. Firmware updates flow through the standard iDRAC workflow, and the operating system recognizes the controller immediately, reducing deployment time for busy IT teams.

This refurbished unit arrives fully tested and ready to use, giving data center managers and edge deployments a cost-conscious way to expand or restore server storage without compromising on genuine Dell quality.
