You need eight 3.5" SATA bays in the ST250 V2 and you don't need the hot swap premium if your maintenance window is a Sunday morning, not a live production run. This simple swap backplane gives you all eight slots, wired for SATA, and plays nice with either an X350 or X40 RAID card or a standalone HBA. Pull the drive, swap it, power back on. Straightforward. No extra firmware dance. It's the part that fits your ST250 V2, from Lenovo ISG
