Product Description
The Broadcom HBA 9500-8e is the external-port member of the HBA 9500 series, designed to connect enterprise-level external storage enclosures to a host server with PCIe Gen 4.0 bandwidth. Built on the eight-lane SAS3808 I/O controller, it addresses up to eight external 12Gb/s SAS, 6Gb/s SATA or NVMe devices through two x4 SFF-8644 (external HD) connectors. Broadcom's Tri-Mode SerDes technology negotiates protocol and speed per drive, letting NVMe, SAS and SATA devices share the same expansion-enclosure bay without a dedicated controller for each. The adapter ships in IT (pass-through) mode by default for direct OS, ZFS or software-defined-storage visibility, with optional IR firmware adding basic RAID 0, 1 and 10 through the SAS3IRCU utility. It is Universal Backplane Management (UBM/SFF-TA-1005) ready, letting customers integrate directly into U.3 backplanes for maximum flexibility and configuration options, and includes hardware secure boot to authenticate firmware before execution.
