Broadcom Avago 9305‑16e PCIe3.0 IT‑Mode 12G SAS Tri‑Mode External‑Only HBA Storage Adapter

Basic Parameter Table

Core Product Features

1. PCIe 3.0 generation pure‑external high‑density IT‑mode HBA card built‑on SAS3216 chip, factory‑flashed with native IT pass‑through firmware, without hardware‑RAID functionality. It is specifically designed for connecting external JBOD disk enclosures for ZFS, TrueNAS and enterprise‑level software‑defined‑storage (SDS) systems.
2. PCIe 3.0 x8 bus bandwidth, four SFF‑8644 external ports, supporting up to 16 external drive channels for off‑server JBOD expansion shelves.
3. Tri‑mode compatibility supports 12G SAS HDD, 6G SATA SSD and U.2 NVMe drives, enabling mixed‑storage deployments of mechanical hard‑disks and solid‑state disks on external disk arrays.
4. Fan‑free passive heat‑sink design, zero‑noise operation, stable for 24/7 continuous long‑term operation inside datacenter rack‑mounted server environments.
5. DOM digital diagnostic monitoring; drive‑health status, link condition and adapter temperature can be checked via the StorCLI command‑line utility for routine system maintenance.
6. Hot‑swap compliant, supporting online hard‑disk replacement without shutting down the host server.

Application Scenarios

• Enterprise‑grade NAS with large‑scale external JBOD disk‑shelf capacity expansion
• Medium‑scale virtualization‑cluster shared external storage pools
• Long‑term cold‑data archiving and disaster‑recovery backup storage systems
• 4K/8K video‑post‑production mass‑storage external disk‑array connection
