  • PCIe 3.0 x8 host interface delivers 12Gb/s throughput
  • 4 x4 SFF-8643 connectors simplify cable routing
  • Supports up to 1024 SATA or SAS terminal devices
  • Includes high and low brackets for flexible mounting

16-port 12 Gb/s HBA

The LSI SAS9305-16i is a host bus adapter that adds 16 internal SATA and SAS ports through a PCIe 3.0 x8 slot. It targets storage builders who need many drive connections without a RAID layer.

Four SFF-8643 connectors

The card provides four x4 internal small SAS HD connectors (SFF-8643) that break out to 16 ports. Both a high bracket and a low-profile bracket are included so the card fits standard and slim chassis alike.

PCIe 3.0 x8 bandwidth ceiling

The x8 Gen 3 link caps aggregate throughput at roughly 8 GB/s, so all 16 ports running at 12 Gb/s cannot be saturated simultaneously. The firmware supports up to 1024 SATA or SAS terminal devices, but the bus width remains the practical bottleneck.

Questions about this item

How many lanes does the PCIe 3.0 x8 interface provide, and what throughput ceiling does that create for the 16 ports?

The card uses an eight-lane PCI Express 3.0 slot, giving roughly 8 GB/s of host bandwidth that all 16 ports share.

Which internal connectors are on the bracket, and how many cables are needed for 16 drives?

Four SFF-8643 mini-SAS HD ports are fitted; each carries four lanes, so four cables connect up to 16 drives.

Does the board ship with both full-height and low-profile brackets, and which screw holes line up?

Yes, a high bracket and a low bracket are included; the card uses standard PCIe mounting holes for either profile.
