AOC-S3816L-L16IT-O Supermicro AOC-S3816L-L16IT 16 Channel PCIe 4.0 x8 Storage Controller

Low-Profile PCIe 4.0 Storage HBA delivering 16-port SAS/SATA connectivity with the AOC-S3816L-L16IT-O

The AOC-S3816L-L16IT-O is a low-profile PCIe add-in storage HBA built on the Broadcom SAS3816 controller to extend SAS/SATA connectivity in modern rack servers and storage nodes. Designed for CPU-centric storage stacks, the AOC-S3816L-L16IT-O operates in true HBA mode (non-RAID), keeping the data path transparent for software-defined storage layers and host-based resiliency.

Using a PCIe 4.0 x8 host interface, the AOC-S3816L-L16IT-O provides the bandwidth required for dense HDD/SSD tiers while preserving PCIe lanes for GPUs, NICs, or NVMe expansion in balanced platforms. SlimSAS device-side connectivity supports clean cabling to external backplanes, expander-based JBOD shelves, or direct attach targets, enabling scalable storage topologies without forcing a RAID abstraction. Secure Boot support helps align the adapter with controlled firmware and measured boot requirements common in regulated environments.

Why Choose the AOC-S3816L-L16IT-O?

The AOC-S3816L-L16IT-O is engineered for high port density in a compact, low-profile form factor, making it practical for 1U and 2U servers where slot and airflow constraints matter. It enables predictable performance and operational consistency for SDS deployments, JBOD attach, and backplane connectivity, while maintaining enterprise reliability and straightforward scale-out by adding additional HBAs per node.

Supermicro designs add-in cards to integrate cleanly with enterprise server platforms, emphasizing validated interoperability, stable firmware processes, and alignment with data center deployment standards. This approach supports long lifecycle operation and consistent serviceability across mixed infrastructure generations.

Key Applications:

• JBOD and expander shelf connectivity
• Software-defined storage nodes
• External backplane SAS/SATA attach
• High-density HDD/SSD storage tiers
