Used Dell 61F54 PCIe 2x M.2 Low Profile Boot Optimized Server Storage-S1 (Boss-S1) RAID Controller Card Storage Adapter for PowerEdge 14G Servers
The 61F54 BOSS-S1 from Dell is a simple RAID solution card designed specifically for booting a server's operating system. The card supports up to two 6 Gbps M.2 SATA drives. The BOSS-S1 adapter card has an x8 connector using PCIe gen 2.0 x2 lanes, available only in the low-profile and full-height form factors. BOSS-S1 card allows you to create only one virtual disk from the available physical disks. Specifying the size of a virtual disk is not supported.
The Dell PowerEdge Boot Optimized Storage Solution (BOSS) S1 provides a highly reliable, and cost-effective solution for segregating operating system boot drives from data on server-internal storage. Many customers, particularly those in the HyperConverged Infrastructure (HCI) arena and those implementing Software Defined Storage (SDS), prefer to separate their operating system drives from data drives, and require hardware RAID mirroring (RAID1) for their OS drives. The main motivation for this is to create a server configuration optimized for application data. Providing a separate, redundant disk solution for the operating system enables a more robust, optimized compute platform.
PowerEdge Engineering developed a simple, cost-effective way of meeting this customer's need. The Boot Optimized Storage Solution uses one or two M.2 SATA devices instead of 2.5" SSD drives to house the OS and utilizes a two-port SATA Hardware RAID controller chip to provide Hardware RAID 1 and Pass-Through capabilities. The M.2 devices offer the same performance as 2.5" SSD drives, and by consolidating the SSDs and controller chip on a single PCIe adapter card, the solution frees up an additional drive slot for data needs.
