Product Description
The Broadcom eHBA 9700W-32i is the highest-port-count member of the 9700 series host bus adapters, built on Broadcom's ninth-generation SAS5132W Tri-Mode I/O Controller silicon and an x16 PCIe Gen 5.0 host interface. As an eHBA rather than a MegaRAID controller, it ships in IT mode, presenting each of its 32 directly attached SAS, SATA or NVMe devices to the host OS, hypervisor or software-defined storage stack without a hardware RAID layer or onboard cache. Two x16 SFF-TA-1016 wide-port connectors deliver 32 internal 24G SAS/SATA/NVMe ports from a single low-profile card, and Broadcom Tri-Mode SerDes technology lets all three protocols operate concurrently, negotiating speed and protocol per device. The adapter is Universal Backplane Management (UBM, SFF-TA-1005) ready and supports hardware secure boot and device attestation for firmware integrity, making it well suited to high-density JBOF, all-flash NVMe and scale-out SDS deployments that need maximum drive density per PCIe slot without RAID overhead.
