The Dell BOSS-S1 Boot Optimized Storage Subsystem (Part Number: 51CN2) is a purpose-built PCIe card designed to host the operating system in Dell PowerEdge servers. It supports up to two M.2 SATA SSDs, offering flexibility in configuring RAID 1 for redundancy or individual disk access. Installed in a low-profile PCIe Gen3 x8 slot, the BOSS-S1 provides a reliable and space-efficient boot drive option that does not consume valuable front-drive bays.
This subsystem is ideal for hyper-converged, virtualization, or database environments where preserving high-speed storage bays for application data is essential. By offloading the OS to dedicated M.2 drives, the BOSS-S1 ensures streamlined system deployment, easier maintenance, and enhanced uptime through RAID protection. Its low-profile design makes it compatible with a broad range of PowerEdge server configurations.
