What is the 9201-16i?

The 9201-16i in this record is an LSI/Broadcom SAS9201-16i storage host bus adapter: a PCIe 3.0 x8 controller card with 16 internal 6Gb/s SAS/SATA ports brought out on four SFF-8643 mini-SAS HD connectors, full-height bracket. Note on the listing title: the queue titles this article a "PLC Digital I/O Module" — that is a misclassification. The board is a server storage controller, not a PLC card. One unit, new, 0.5 kg. 6 photos and 1 video below show the exact board covered by this record.

Values are read from the board silkscreen and barcodes in the photo set; the port count follows the SAS9201-16i datasheet for this board marking.

How the sixteen ports are wired

All four SFF-8643 connectors face the same direction along the board edge, and each one carries four SAS/SATA lanes — sixteen drives total. In a backplane server chassis, one SFF-8643-to-SFF-8643 cable links the card to a four-lane backplane segment; in a tower build with loose drives, a reverse-breakout cable fans each connector out to four individual SATA data plugs. The 6 Gb/s rate per lane is shared per drive, not aggregated, so a mixed SAS/SATA bench is fine but no single drive sees more than 6 Gb/s. Two pin headers sit between the connectors and the bracket edge — the Ext LED block and the per-port activity block for chassis front-panel indicators.

About the title and the origin note

This article's listing title was generated as a "PLC Digital I/O Module" page; the board itself settles the question — the barcodes read SAS9201-16I with an LSI-format SAS address (500605B) and FCC ID N4H32, and the layout matches the official 9201-16i design. The intake record books this unit as a China-made replacement build, new, with a 1-year warranty, and that is how KOEED sells it. If you need a factory-shipped card with vendor support, confirm the expectation before ordering; if you need the hardware function — sixteen 6 Gb/s SAS/SATA lanes on a PCIe 3.0 x8 slot — the board in the photos is what ships.
