LSI

LSI 9500-16i 12Gb/s SAS SATA NVME Tri-Mode Host Bus Adapter

SKU CH-YWEA-V6AH2

Connects up to 1024 SAS or SATA drives and 32 NVMe devices at 12 Gb/s through two SFF-8654 ports on a PCIe 4.0 x8 host interface

  • Supports 1024 SAS/SATA devices for massive storage scaling
  • Connects 32 NVME drives for high-speed flash arrays
  • 12Gb/s SAS bandwidth accelerates data-intensive workloads
  • PCIe Gen 4.0 x8 host interface maximises throughput
  • Dual SFF-8654 ports enable flexible Tri-Mode connectivity

Controller and Interface

The LSI 9500-16i is a new Broadcom SAS3816 host bus adapter that connects SAS, SATA and NVMe drives through a single PCIe Gen 4.0 x8 slot. It suits server builders and storage integrators who need tri-mode flexibility without adding multiple controllers.

Port Count and Topology

Two x8 SFF-8654 SlimSAS ports deliver up to 16 internal lanes, supporting 1024 SAS or SATA devices and 32 NVMe targets. Buyers who require more than two physical ports or external connectivity will need a different adapter.

Thermals and Power

The low-profile card ships with both high and low brackets for standard or dense chassis. Passive cooling relies on system airflow; no onboard fan is present and no separate power connector is required beyond the slot.

Questions about this item

What does the 12Gb/s SAS rating actually deliver when the card is installed in a server?

The 12Gb/s SAS rating gives each attached SAS drive up to 12Gb/s bandwidth, while SATA drives run at 6Gb/s and NVMe devices use PCIe Gen 4.0 lanes through the same ports.

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

PCIe Gen 4.0 x8 provides roughly 16GB/s of host bandwidth, which caps combined SAS, SATA and NVMe traffic to that ceiling even though individual ports can signal at 12Gb/s.

What bracket and slot clearance does the 9500-16i need to fit in a chassis?

The package includes both a high bracket and a low bracket, so the card fits standard full-height and low-profile PCIe x8 or x16 slots with the appropriate bracket installed.
