  • Product typeController Card
  • 12 Gbps data transfer for high-throughput storage
  • PCI Express 3.0 x8 host interface for server bandwidth
  • Eight SAS ports connect multiple drives
  • Hardware RAID controller offloads parity calculations
  • Supermicro server-grade build for data-centre reliability

Supermicro AOM-S3108M-H8 12Gbps SAS RAID Card

The Supermicro AOM-S3108M-H8 is a 12Gbps PCI Express 3.0 x8 controller card designed for server environments. It provides eight SAS ports for connecting multiple drives to a single expansion slot. This add-on card targets administrators building high-density storage arrays in rackmount systems.

Suits admins needing eight SAS lanes on one x8 slot

This card suits IT professionals deploying hardware RAID across eight SAS drives in compatible Supermicro chassis. Builders requiring more than eight ports or a different PCIe generation should look at alternative controllers. Systems lacking an available PCI Express 3.0 x8 slot cannot accommodate this specific part.

12Gbps SAS throughput per port

Each of the eight ports delivers a 12Gbps data transfer rate, setting the maximum bandwidth available to every attached drive. The 3108 RAID processor manages the array operations across all connected devices. Match this throughput spec to your drive capabilities to confirm the card meets the performance target.

Questions about this item

Does the 12 Gbps SAS interface share bandwidth with the PCI Express 3.0 x8 host slot under sustained workloads?

The card runs at 12 Gbps per SAS port across the PCI Express 3.0 x8 link, so the host slot provides the ceiling for aggregate throughput.

How much heat does the controller produce when all eight SAS ports run continuously?

The board draws power through the PCI Express 3.0 x8 slot and relies on server chassis airflow; no active cooler is fitted.

Which cables or backplanes are required to connect drives to the eight SAS ports?

Each port accepts standard SAS cables or a backplane with matching SAS connectors; no proprietary interconnects are used.
