Dell BOSS-S1 Card Kit with 2x 1TB M.2 SSD

Refurbished Dell BOSS-S1 2x 1TB kit, the high-capacity boot mirror for a PCIe slot in Dell 14th and 15th gen PowerEdge servers. Dell BOSS mirrors two M.2 SATA SSDs in hardware RAID 1 on a dedicated controller, so the operating system boots off the front bays and does not use a PERC channel. Dell supports one virtual disk per card, so the pair is the boot volume and nothing else.

Specifications

Compatibility

BOSS-S1 is a PCIe adapter holding two 80mm M.2 SATA SSDs; it does not run NVMe M.2. Dell supports RAID 1 or non-RAID, no RAID 0, one virtual disk. There are no drive LEDs and no hot-plug; a drive swap means powering down. Some 15th gen chassis take the S1 as an integrated-slot module, so confirm yours takes the adapter form.

When to Choose This

The 1TB pair suits a Linux root that also holds container images, a local package mirror or long log retention, or Windows Server with large crash dumps and application data on the boot volume. For hypervisor boot alone, the 240GB kit does the same job. Fair warning: Dell's BOSS-S1 drive list names 240GB and 480GB SSDs, so if a support contract requires Dell-listed drives, take the 480GB kit.
