The SX03-0B00-00 is a SAS35xR series 12Gb/s SAS/SATA expander IC from Broadcom. A SAS expander acts as a switch inside a storage topology, letting a small number of host controller links reach a much larger population of SAS and SATA drives than direct attachment allows, and handling the routing and connection management between initiators and targets. The SX03-0B00-00 is listed with 3 ports and carries a REACH SVHC status of Yes.

SAS expanders sit on storage backplanes and in JBOD enclosures, fanning out a handful of host bus adapter links to dozens of drive bays so that a single controller can address a full shelf. They are also used inside server chassis to connect the internal drive cage and to cascade enclosures into larger arrays. Support for both SAS and SATA targets lets one backplane mix enterprise and nearline drives. Buyers are typically storage system and server OEMs, backplane and enclosure manufacturers, and integrators building or servicing direct-attached and JBOD storage.
