Broadcom LSI 9405W‑16e PCIe3.1 Tri‑Mode IT‑Mode External‑Only HBA Storage Adapter

Basic Parameter Table

Core Product Features

1. High‑bandwidth PCIe3.1 x16 pure‑external IT‑mode HBA card built on SAS3616W chip, factory‑flashed with pure IT pass‑through firmware without onboard hardware‑RAID, specifically built for high‑density external JBOD disk‑shelf expansion.
2. PCIe 3.1 x16 full‑speed bus, four SFF‑8644 external connectors, supporting up to 16 external drive channels, eliminating PCIe bandwidth bottlenecks for large‑scale off‑server storage arrays.
3. Full tri‑mode compatibility, supporting 12G SAS HDD, 6G SATA SSD and U.2 NVMe drives, enabling mixed deployment of mechanical hard‑disks and flash‑based solid‑state drives on external JBOD enclosures.
4. Fan‑less passive fin‑type heat sink, zero‑noise design, capable of stable 24/7 non‑stop operation inside data‑center rack‑mounted server environments.
5. DOM digital diagnostic monitoring, which can check link status, adapter temperature and operating voltage via the StorCLI command‑line utility for routine storage‑system maintenance.
6. Hot‑swap‑compliant; supports online hard‑disk replacement without host server shutdown, ideal for enterprise‑scale NAS, cold‑archive backup, video surveillance and scale‑out virtualization shared‑storage pools.

Application Scenarios

• Enterprise‑grade NAS with high‑density external JBOD disk‑shelf expansion
• Large‑scale virtualization‑cluster shared external storage pool deployment
• Long‑term cold‑data archiving, disaster‑recovery backup storage systems
• 4K/8K video‑production post‑processing mass‑storage disk‑array connection
