Astera Labs Unveils PCIe 6 Scorpio Switches for Cloud-Scale AI Platforms

In Focus: PCIe

🖥️ PCI Express (PCIe) High-Speed Interconnect for Servers, AI Accelerators and Storage
PCI Express (PCIe) is the industry’s standard high-speed serial interconnect used to connect CPUs, GPUs, AI accelerators, networking adapters, storage devices and other peripherals within modern servers. Successive generations of PCIe continue to double bandwidth while maintaining software compatibility, making PCIe a foundational building block for AI infrastructure and cloud computing.
Why It Matters	AI servers rely on PCIe to move massive volumes of data between processors, GPUs, DPUs, NICs and storage devices. PCIe 5.0, 6.0 and emerging 7.0 technologies continue to expand bandwidth required for increasingly demanding AI, cloud and high-performance computing workloads.
