Dell R450/R650XS BOSS S1 Controller Card

This Dell BOSS S1 controller card provides dedicated boot-storage controller support for PowerEdge R450 and R650xs servers, with additional use in PowerEdge MX740c and MX840c systems that support the BOSS S1 module. It works with the server’s Dell BOSS boot-storage hardware so operating-system media can be kept separate from the primary front-bay drive backplane; compatibility depends on the rear BOSS card location, the correct BOSS carrier or module hardware, the required internal power/data cabling, and firmware support for the BOSS S1 controller.
