CKNXG Dell 8x 2.5-inch PERC S140 BP AB Mini SAS HD to MB Software RAID Cable for PowerEdge R840

The CKNXG Dell cable is designed specifically for integration with Dell PowerEdge R840 servers, providing a direct Mini‑SAS connection between the hard‑drive backplane and the motherboard. Engineered for use with eight 2.5‑inch drives, it supports the PERC S140 controller and facilitates software‑based RAID configurations. The cable’s designation “BP AB” indicates its role in linking the backplane (BP) to the system board (AB), ensuring reliable data pathways for storage arrays. Compatibility is limited to Dell PowerEdge R840 platforms equipped with the PERC S140 controller, making it a targeted solution for maintaining optimal RAID performance in those environments.
