Broadcom PEX89144 PCIe Gen5 Switch

The Broadcom PEX89144 is a 144-lane PCIe Gen5 switch silicon designed for next-generation AI servers and high-performance storage platforms. It enables efficient fan-out and routing of GPU and NVMe traffic with full PCIe 5.0 bandwidth support, delivering low-latency interconnect for compute and storage acceleration workloads.

The device supports advanced traffic management, QoS capabilities, and flexible lane configuration to accommodate diverse endpoint requirements. With 144 total PCIe Gen5 lanes, the switch provides multiple port configurations enabling simultaneous GPU clustering, NVMe expansion, and inter-server connectivity in densely-packed infrastructure environments.

Ideal for

• Multi-GPU acceleration farms with direct GPU-to-GPU communication and unified memory fabric
• High-capacity NVMe storage expansion and tiering in AI training and inference clusters
• Low-latency GPU cluster interconnect for distributed deep learning and LLM workloads
• Storage array pooling with direct-attach NVMe and SSD expansion in enterprise data centers
• Real-time analytics platforms requiring high-bandwidth data movement between compute and storage
• Hyperscale infrastructure consolidation reducing server footprint while increasing per-node I/O capacity
