The Broadcom HBA 9500-16i is a high-speed non-RAID host bus adapter built on the SAS3816 I/O controller for unbuffered direct-attached storage. Capable of driving over 3 million IOPS across 16 internal lanes of PCIe 4.0, it is the premier choice for ZFS file servers, VMware vSAN nodes, and Ceph OSDs requiring Tri-Mode SAS/SATA/NVMe connectivity. Buyers sourcing second-hand 9500-16i HBAs should verify IT-mode firmware revision, check SlimSAS internal receptacles for damage, and verify low-profile vs full-height brackets.

Compatibility
Compatible with PCIe 4.0 x8 and x16 slots across enterprise server platforms. Interfaces with server drive backplanes through two internal SlimSAS SFF-8654 x8 connectors. Because it is a pure HBA, it does not require battery backup modules or cache memory. It will not configure hardware RAID arrays (RAID 5 or 6).
How to identify a genuine unit
The green low-profile card features a label showing Broadcom 05-50076-00 and model HBA 9500-16i. It features two x8 SlimSAS connectors. In system BIOS, TrueNAS, and Linux dmesg, the card identifies under the mpt3sas kernel driver as a Broadcom SAS3816 host bus adapter.
Buying used
Verify that the HBA is running official IT-mode firmware. Inspect the SlimSAS connector shells for hairline fractures or bent pins. Check that the gold PCIe card edge fingers are clean and that the appropriate low-profile or full-height bracket is installed.
