Mingjiada Supply/Recycle Broadcom PEX89024 24-Lane 24-Port Managed PCI Express Gen 5.0 Switches

Shenzhen Mingjiada Electronics Co., Ltd. — as a professional electronic component supply chain service provider — has long been supplying and purchasing used Broadcom PEX89024 PCIe 5.0 switches. This device meets the demands for ultimate connectivity in data centres, cloud computing platforms and high-performance computing (HPC) systems.

I. Core Product Overview: The Cornerstone of Connectivity in the PCIe 5.0 Era
The PEX89024 is a high-performance, managed PCI Express 5.0 switch within Broadcom’s PEX89000 series, offering a flexible configuration of 24 lanes and 24 ports. As an industry-leading PCIe Gen 5.0 (32 GT/s) switching solution, it integrates Broadcom’s proprietary high-performance SerDes technology with an embedded ARM CPU. Designed specifically for data centres, AI/ML inference clusters, NVMe storage systems and edge computing servers, it aims to resolve bottlenecks in high-bandwidth, low-latency and multi-host interconnectivity.
The PEX89024 is the entry-level, high-density model in the PEX89000 family. It delivers full fabric management capabilities within a 29x29 mm BGA package, serving as a key interconnect component for building composable hyperscale computing systems.

II. Key Technical Specifications (PEX89024)
Model: PEX89024, managed switch
PCIe Standard: PCI Express 5.0 (Gen 5), backwards compatible with Gen 4/3/2/1
Data Rate: 32 GT/s per lane, with integrated Broadcom 32-GT/s SerDes
Lanes/Ports: 24 lanes / 24 ports, with any port configurable as upstream or downstream
Link Width: Selectable from x1, x2, x4, x8, x16; port speeds are independent of one another
Embedded CPU: Dual-core ARM A15, for management, monitoring, hot-swapping and I/O allocation
Latency performance: < 115 ns (through-packet latency), at line-rate
Typical power consumption: Approx. 14 W, half the power consumption of the previous generation at the same bandwidth
Package dimensions: 29 x 29 mm BGA

III. Key Features (PEX89024)
1. Multi-host Connectivity and I/O Sharing
The PEX89024 supports I/O sharing via standard SR-IOV (Single Root I/O Virtualisation) or multi-function devices, allowing multiple host devices to connect to the same switch and enabling dynamic allocation of I/O resources. This lays the foundation for building highly available and hyperscale systems.
2. Embedded Dual-Core ARM Processor
Each PEX89000 series switch integrates an embedded dual-core ARM CPU. This processor is used to configure switch functions, create hierarchical structures, perform I/O allocation and management, and handle tasks such as hot-swapping and interrupts, thereby significantly reducing the load on the main CPU.
3. Tunneled Windows Connection (TWC)
The PEX89024 incorporates the specialised Tunneled Windows Connection (TWC) feature, enabling ultra-low-latency host-to-host communication for short data packets. This is crucial for AI/ML clusters that require frequent inter-node communication.
4. Advanced Management and Reliability
Quality of Service (QoS): Supports eight traffic classes (TCs), ensuring that mission-critical data transmission is given priority.
High Reliability: Features such as hardware-based secure boot and authentication, DPC/eDPC support, and hot-swap capability ensure stable 24/7 system operation.

IV. Wide Range of Application Scenarios
Thanks to its high bandwidth, low latency and flexible topology, the PEX89024 is ideal for the following applications:
AI/ML acceleration clusters: Providing high-speed, low-latency interconnects between GPUs or AI accelerators, it is a key component in building AI training and inference servers.
Hyper-converged Infrastructure (HCI): Overcomes the limitations of traditional PCIe topologies to achieve complete decoupling and pooling of computing and storage resources.
Data Centre Servers and Storage: Used to expand host PCIe ports to connect a large number of NVMe solid-state drives (SSDs) or other I/O devices.
NVMe All-Flash Arrays (AFA): The PEX89024 is specifically designed to support NVMe all-flash arrays and hybrid storage systems. Its embedded CPU handles tasks such as device configuration, chassis management and LED control.
