Broadcom 9500‑16i 12 Gb/s Tri‑Mode HBA (16 Ports)

The Broadcom 9500‑16i is a high‑port, high‑performance internal HBA designed for servers, workstations and enterprise‑class storage systems. It supports SAS, SATA and NVMe devices via a “tri‑mode” interface, with PCI Express 4.0 x8 host connectivity and sixteen internal ports—ideal for connecting large arrays of drives or high‑density storage enclosures. :contentReference[oaicite:1]{index=1}

Key Features

• 16 internal ports: Two x8 Mini‑SAS HD/SlimSAS (SFF‑8654) internal connectors providing 16 device channels. :contentReference[oaicite:2]{index=2}
• Tri‑Mode interface: Supports SAS at 12 Gb/s, SATA at 6 Gb/s and NVMe (via PCIe 4.0 host) within one adapter. :contentReference[oaicite:3]{index=3}
• Host Bus Interface: PCI Express 4.0 x8 lanes (and backward compatible) enabling high throughput. :contentReference[oaicite:4]{index=4}
• Massive device support: Up to 1,024 SAS/SATA devices or up to 32 NVMe devices supported in the right configuration. :contentReference[oaicite:5]{index=5}
• Enterprise features: Hardware secure boot, UBM readiness (Universal Bay Management), and management via StorCLI/LSA. :contentReference[oaicite:6]{index=6}
• Low power footprint: Typical power consumption around ~8.9 W. :contentReference[oaicite:7]{index=7}

Specifications (Selected)

• Controller: SAS3816. :contentReference[oaicite:8]{index=8}
• Internal Ports: 16 (via 2 connectors) :contentReference[oaicite:9]{index=9}
• Supported Devices: Up to 1024 SAS/SATA, up to 32 NVMe. :contentReference[oaicite:10]{index=10}
• Physical Dimensions: Low profile size ~155.5 mm × 68.8 mm (6.127″ × 2.712″). :contentReference[oaicite:11]{index=11}
• Operating Temp & Humidity: 0 °C to 55 °C; humidity 20 %–80% non‑condensing. :contentReference[oaicite:12]{index=12}
• Warranty & MTBF: MTBF > 5,000,000 hours; 3‑year warranty. :contentReference[oaicite:13]{index=13}

Use Cases

• Building a high‑density storage server: connecting many SAS/SATA drives directly to this one adapter.
• Upgrading storage connectivity in workstations requiring large arrays of drives or SSD/NVMe configurations.
• Deploying in 1U/2U rack systems where low‑profile form factor and high throughput are important.

Compatibility & Considerations

• To achieve full performance you should use a PCIe 4.0 x8 slot; if used in PCIe 3.0 or fewer lanes the bandwidth may be limited. :contentReference[oaicite:14]{index=14}
• Even though SAS supports up to 12 Gb/s per port, actual throughput depends on connected drives/backplane and system architecture. :contentReference[oaicite:15]{index=15}
• Ensure system cooling and airflow; enterprise‑class cards like this can run warm, especially in dense server chassis. :contentReference[oaicite:16]{index=16}
