Supermicro AOC-S3108L-H8IR-16DD RAID Controller

The Supermicro AOC-S3108L-H8IR-16DD is a low-profile MegaRAID SAS3 add-on card built around a Broadcom 3108 controller that provides eight internal SAS-3 ports with up to 12 Gb/s per port and a PCIe 3.0 host interface. It ships with 2 GB of on‑card DDR3 cache (1866 MHz) and an on‑board hardware I/O processor to accelerate RAID operations. The card supports RAID levels 0, 1, 5, 6, 10, 50, and 60, offering a range of performance and redundancy options for different workloads. Although it has eight physical internal ports, it can connect up to 16 hard drives when used with an appropriate expander or backplane, enabling high‑density storage in 8‑bay chassis or larger configurations. The AOC-S3108L-H8IR-16DD is offered in a low-profile form factor suitable for compact servers and backplanes, making it compatible with Supermicro systems and other platforms that provide standard PCIe and SAS backplane connectivity. Typical applications include enterprise storage pools, virtualization environments, databases, and other data‑intensive workloads that require reliable SAS/SATA connectivity and hardware RAID acceleration.
