Supermicro BPN-SAS-826A 2U Hard Drive Backplane

The Supermicro BPN-SAS-826A is a 12-port, 2U SAS/SATA backplane intended for 2U Supermicro chassis such as the SC826A/SC826 family. It supports up to 12 x 3.5‑inch SAS2/SATA3 HDDs or SSDs and routes each drive’s signals to a host controller through three internal SFF-8087 connectors, four drives per connector, delivering direct, backplane‑to‑controller connectivity. This backplane is designed to fit in 2U storage configurations where all 12 front bays are used, matching the capacity of the SC826 series and similar backplane‑compatible enclosures, and relies on the server’s SAS controller for drive management. Pair it with a compatible SAS/SATA controller and the appropriate internal cabling in a supported 2U chassis to create a dense storage expansion or JBOD setup for enterprise or workstation‑grade deployments.
