LSI Logic 16-Ports SATA 6Gb/s / SAS 12Gb/s PCI-Express 3.0 x8 High Profile Host Bus Adapter (HBA) – 9305-16I

LSI Logic 9305-16I 16-Port SAS 12Gb/s / SATA 6Gb/s PCIe 3.0 x8 High Profile HBA — 9305-16I

The LSI Logic 9305-16I is a 16-port SAS 12Gb/s / SATA 6Gb/s host bus adapter (HBA) with PCIe 3.0 x8 host interface in a high-profile form factor. Based on the LSI SAS3224 controller, it provides high-density internal SAS/SATA connectivity for servers requiring maximum drive count in IT mode (JBOD pass-through) for ZFS, software RAID, and large-scale storage deployments.

Key Features

• 16x internal SAS 12Gb/s / SATA 6Gb/s ports

Frequently Asked Questions

What is the difference between 9305-16I and 05-25703-00?

The 9305-16I is the high-profile (full-height) version, while 05-25703-00 is the low-profile version of the same LSI SAS 9305-16i HBA. Select based on your server chassis bracket requirements.

Does this support IT mode?

Yes — the 9305-16I ships in IT mode (initiator/target), presenting each drive individually to the OS without hardware RAID. This is required for ZFS, TrueNAS, and software RAID deployments.

The LSI Logic 9305-16I delivers 16-port SAS 12Gb/s / SATA 6Gb/s internal connectivity over PCIe 3.0 x8 in a high-profile form factor — a high-density IT mode HBA for ZFS, software RAID, and large-scale SAS/SATA storage deployments.
