LSI 9205-8i SAS RAID controller IT mode

This LSI 9205-8i host bus adapter arrives flashed to IT mode for direct drive access. It presents eight 6 Gbps SAS lanes through two internal SFF-8087 connectors and installs in a PCI Express slot. The card is aimed at builders running ZFS on TrueNAS CORE or FreeNAS and at unRAID users who need extra SAS or SATA ports without hardware RAID overhead. Two Mini-SAS cables are included in the box.

Thermals and power in normal use

The controller draws modest power from the PCI Express bus and runs passively cooled in typical server chassis airflow. No onboard fan is fitted so acoustic output is negligible when case fans provide adequate circulation. Power consumption remains low during sustained array scrubs or parity checks. Thermal behaviour will depend on the enclosure airflow rather than the card itself.

Questions about this item

How do I install the 9205-8i and which step is often missed?

Seat the 9205-8i in a PCI E slot, then connect the two 8087 cables to the internal Mini-SAS ports; the step often missed is flashing the card to IT mode before adding drives.

What maintenance will the 9205-8i need later?

The 9205-8i has no moving parts, so only occasional firmware updates and checking the 8087 cable connections are required.
