IDSDM or vFlash card Mounted in a dedicated slot at the rear of the chassis, the IDSDM with vFlash module runs on a Dell EMC-proprietary PCIe x1 slot via USB 3.0. The PowerEdge R440 shifts card format from SD to microSD, supporting 16GB, 32GB, or 64GB for IDSDM and a fixed 16GB for vFlash, with an onboard write-protect switch built into the module. Boot Optimized Storage Subsystem (BOSS) BOSS supplies a fast, alternate location for OS installation, freeing up drive-based storage for data use instead. Built specifically for OS booting, this RAID solution card supports up to two 6Gbps M.2 SATA drives through an x8 connector on PCIe Gen2 x2 lanes, available only in low-profile, half-height form factor.
