  • PCIe 4.0 x8 host bus delivers 22.5 Gb/s SAS bandwidth
  • Two SFF-8654 SlimSAS connectors simplify internal cabling
  • RAID 0, 1, 10 with hot-spare support protects data
  • MTBF exceeds 5,000,000 hours at 40 °C for long-term reliability

Tri-Mode Storage Adapter for 16 Internal Drives

The Broadcom 9620-16I is a Tri-Mode RAID controller built for servers that need to mix SAS and SATA drives behind a single adapter. It presents 16 internal ports through two x8 SFF-8654 connectors, allowing dense backplane configurations without additional HBAs. The card supports RAID 0, 1 and 10 with hot-spare capability, making it suited for entry-level redundancy on direct-attached storage.

PCIe 4.0 x8 Link Limits Aggregate Throughput

The host interface is an eight-lane PCI Express 4.0 connection, which caps total bandwidth at the slot level. Individual ports can run at 22.5, 12 or 6 Gb/s for SAS and 6 Gb/s for SATA, but simultaneous traffic across all 16 ports cannot exceed the x8 upstream limit. Workloads that saturate many high-speed SAS drives will hit the bus ceiling before the per-port rates.

Low-Profile Card Installs in Standard x8

The adapter fits a standard low-profile bracket and requires only a PCIe 4.0 x8 slot, though it will also seat in an x16 slot at x8 electrical width. The two SFF-8654 connectors use SlimSAS cables that are keyed but fragile; forcing a misaligned cable can damage the receptacle pins. Firmware and driver versions must match the server platform, otherwise the controller may not enumerate at boot.

Questions about this item

How do I decide between the two internal connectors when planning my drive layout?

The card provides two x8 SFF-8654 SlimSAS connectors, each carrying eight lanes for a total of sixteen internal ports.

What does the 24G generation rating mean for throughput inside my server?

It indicates the adapter supports SAS signalling up to 22.5 Gb/s, 12 Gb/s and 6 Gb/s, plus SATA at 6 Gb/s.

How does the PCIe 4.0 x8 host interface limit real-world performance?

The eight-lane PCIe 4.0 link caps aggregate bandwidth at the bus level, so sustained throughput cannot exceed that ceiling.
