Description For Dell K4D64 PCIe 2x M.2 Boss-S1 RAID Controller Card for PowerEdge 14G
The Dell K4D64 BOSS-S1 PCIe RAID Controller Card is a specialized boot-optimized storage adapter designed to deliver simple, reliable operating system storage for Dell PowerEdge 14th-generation servers. It provides two M.2 SATA SSD slots, allowing the installation of SATA-based M.2 drives that host the server’s boot volume. Through built-in hardware RAID 1 support, the K4D64 enables mirrored configurations, meaning the OS remains available even if one SSD fails — a key feature for mission-critical and always-on environments.
This controller card connects via a PCIe Gen 2.0 ×8 interface (with two electrical PCIe lanes), and supports both RAID and non-RAID modes. It creates a single virtual disk for the system boot drive when RAID is used, with a fixed 64 KB stripe size and standard write-through caching for data integrity. Unlike full-featured RAID adapters, the BOSS-S1 does not include a battery backup or non-volatile cache.
Optimized for system boot and OS storage, the K4D64 frees up traditional drive bays for data storage by placing the OS on dedicated M.2 SSDs — a valuable advantage in dense server configurations. It’s widely deployed across PowerEdge models such as R240, R440, R540, R640, R740, R740xd, T140, T340, T440, and T640 series servers.
