Eight-port HBA for storage arrays

The LSI 9207-8i is a host bus adapter built around the SAS2308 controller. It presents eight SAS or SATA lanes through two SFF-8087 connectors. The card targets home-lab builders and small-business servers running ZFS, FreeNAS or unRAID who need direct drive access without RAID abstraction. Firmware ships in IT mode P20 (20.00.07.00) for passthrough operation.

Thermals and power in typical service

The PCIe 3.0 x8 interface supplies the card, drawing modest power during normal drive enumeration and background scrubbing. No active cooling is included; airflow from a standard server chassis keeps the controller within spec. Acoustic output is limited to the system fans, so the adapter adds no audible noise of its own.

Behaviour under sustained workload

During long rebuilds or parity checks the SAS2308 maintains 6Gpbs per lane across all eight ports. The IT mode firmware avoids write-back caching, so throughput scales linearly with the attached drives. Thermal throttling is unlikely in a ventilated enclosure, and the low-profile bracket option fits dense multi-node racks.

Questions about this item

How do I install the 9207-8i HBA into a PCIe 3.0 x8 slot and attach the SFF-8087 cables?

Insert the card into a PCIe 3.0 x8 slot, secure it with the included high or low-profile bracket, then connect the two supplied SFF-8087 cables to the card's internal ports and to your backplane or drive cages.

What firmware maintenance does the IT Mode P20 (20.00.07.00) release on the SAS2308 controller require?

The card ships with IT Mode P20 firmware; check the vendor's support site periodically for newer P20 releases and flash them using the provided UEFI or DOS tools to keep compatibility with ZFS, FreeNAS or unRAID.

At what throughput limit does the 6Gbps SAS link saturate during sustained transfers?

Each of the eight lanes tops out at 6Gbps, so sustained sequential workloads across all ports will hit the 6Gbps per-lane ceiling before the PCIe 3.0 x8 host interface becomes a bottleneck.
