A demonstration at DesignCon 2025 showcased a multitude of ”firsts” for a single demo, highlighting the potential of PCIe 6.x technology. The collaboration between micron and Astera Labs resulted in the first public demonstration of end-to-end interoperability between a PCIe 6.x switch and a PCIe 6.x SSD.
The Growing Demand for High-Speed Data Transfer
The world of AI relies heavily on data, necessitating faster data transfer rates through cutting-edge storage hardware. The PCI Special Interest Group is actively developing PCIe 6.0 and 7.0 standards to address these demands.However, certain challenges need resolution before widespread adoption.
Last year, Micron teased its first PCIE 6 SSD, promising impressive bandwidth rates. More recently, the U.S. memory manufacturer partnered with switch maker Astera Labs to showcase the new drives in action.
DesignCon 2025: A Showcase of Innovation
The DesignCon demo featured a Micron “data center” SSD connected to an Astera Labs’ P Scorpion series fabric switch. This combination achieved sequential read speeds exceeding 27 GB/s. In 2024, Micron claimed its PCIE 6 drive would offer up to 26 GB/s sequential read speeds, a figure surpassed in this demonstration.
Astera notes that the P Scorpion series fabric switch is the first specifically designed for PCIe 6 devices. This custom-built switch can handle 64 PCIE 6.x lanes and features a 4-port architecture. It efficiently manages data flows from GPUs, CPUs, SSDs, and NICs.
Overcoming Technological Hurdles
The specifications for PCIe 6 and PCIe 7 are still under development as companies explore methods to mitigate speed throttling caused by excessive heat generated by the new bus technology.
Achieving over 27 gigabits per second required a creative approach to connection management. Astera connected its switch to an unspecified processor, an NVIDIA H100 GPU, and two Micron PCIe 6.x E3.S SSDs. The demo utilized NVIDIA’s GPUDIRECT storage technology to establish a direct data path between the GPU and SSDs.
The Impact of PCIe 6.x on AI and Cloud Infrastructure
Astera Labs asserts that PCIE 6.x is becoming essential for building improved AI and cloud infrastructures. the new standard can double the bandwidth of PCIE 5.0 devices, offering up to 256 GB/s of bi-directional data rates on an x16 lane.
The low-latency, high-speed architecture should provide sufficient data to saturate AI-related workloads. The demonstration suggests that PCIe 6.x is now ready for data center implementation. However, mainstream PC products are not expected to feature PCIe 6-compatible motherboards soon.
Key Takeaways from the Demonstration
