LSI Logic 9300-8i 8-Port SATA 6Gb/s / SAS 12Gb/s PCIe 3.0 x8 Low Profile Host Bus Adapter — 9300-8I

The LSI Logic 9300-8i (9300-8I) is a high-performance 8-port SATA 6Gb/s and SAS 12Gb/s Host Bus Adapter (HBA) featuring a PCI-Express 3.0 x8 interface in a low-profile form factor. Designed for IT Mode (JBOD) operation, it provides direct pass-through access to connected drives — ideal for software RAID, ZFS, and storage server deployments requiring native drive access without hardware RAID overhead.

Key Features

• 8 internal SAS 12Gb/s / SATA 6Gb/s ports for high-throughput storage connectivity

Frequently Asked Questions

What is the difference between an HBA and a RAID controller?

An HBA (Host Bus Adapter) in IT Mode passes drives directly to the OS without hardware RAID, allowing software RAID or ZFS to manage the drives. A RAID controller manages drives in hardware RAID arrays. The 9300-8i operates in IT Mode for direct drive access.

Is the LSI 9300-8i compatible with ZFS / TrueNAS?

Yes, the LSI 9300-8i in IT Mode is one of the most widely recommended HBAs for ZFS-based storage platforms including FreeNAS, TrueNAS, and Unraid.

How many drives can the 9300-8i support?

The 9300-8i supports 8 direct-attached drives, expandable to up to 1,024 drives with SAS expanders.

The LSI Logic 9300-8i is the go-to HBA for ZFS, software RAID, and high-density storage server deployments requiring direct drive pass-through. Order today for proven LSI/Broadcom HBA performance in IT Mode.
