Unordered IO for Improving Performance and Efficiency of PCIe® Fabrics - ERP Spain.com - España y América Latina

As the role of PCI Express® (PCIe®) technology expands in new areas such as AI/ML, PCI-SIG® has recognized the need to support multi-path fabrics with an ordering model to improve PCIe bandwidth and reduce latency while maintaining backwards compatibility. Unordered IO (UIO) is a new feature added to the PCIe 6.1 specification that defines a new wire semantic protocol and related capabilities for addressing the limitations of the existing PCIe fabric-enforced ordering rules, while keeping the producer-consumer ordering model intact. UIO is a key enabler for Multi-Link PCIe devices (i.e., non-tree topologies). UIO also helps improve the interaction with other protocols, including on-die/on-package protocols, such as CXL, UCIe, etc. Attendees of this webinar will understand the traditional PCIe ordering model, the system-level considerations and tradeoffs for deploying PCIe Unordered IO, and will learn which applications and market segments will benefit most from deploying UIO.
