Broadcom LSI 9405W‑16i PCIe3.1 Tri‑Mode IT‑Mode Internal HBA Storage Adapter

Basic Parameter Table

Core Product Features

1. High‑bandwidth PCIe3.1 x16 IT‑mode HBA card built on SAS3616W controller chip, pure pass‑through firmware without hardware RAID, optimized for high‑density 16‑bay self‑built NAS, ZFS/TrueNAS storage servers.
2. PCIe 3.1 x16 full‑speed bus, four SFF‑8643 internal ports, supports up to 16 internal drives, eliminating PCIe bandwidth bottlenecks for high‑capacity multi‑disk storage arrays.
3. Full tri‑mode compatibility, supports 12G SAS mechanical hard drives, 6G SATA SSD, U.2 NVMe solid‑state drives, supporting mixed‑storage deployment of HDDs and NVMe SSDs.
4. Fan‑less passive fin‑type heat sink, zero‑noise design, stable 24/7 long‑term continuous operation for rack‑mounted server chassis.
5. DOM digital diagnostic monitoring, which can monitor link status, card temperature and working voltage via the StorCLI command‑line tool for daily O&M management.
6. Hot‑swap compliant, allows online hard‑disk replacement without shutting down the host server; the x16 PCIe form factor is ideal for high‑performance virtualization nodes and large‑capacity private‑cloud storage nodes.

Application Scenarios

• High‑density 16‑bay and above rack‑mounted TrueNAS/ZFS enterprise NAS servers
• Large‑scale virtualization host multi‑disk software‑defined storage pool construction
