When training AI models, networks are no longer mere pipes. In a collective communication environment where tens of thousands of GPUs exchange data, a single packet loss becomes a critical bottleneck that delays the entire Joint Training Completion (JCT). At last year’s HPE Discover Barcelona, HPE and VIAVI Solutions presented a remarkable demonstration signaling a fundamental transformation of Ethernet…
In the previous post, we looked into what RoCE is and why it is necessary. Now, let's explore how to implement RoCE on AOS-CX switches. To configure RoCEv2 on HPE Aruba Networking CX switches, the following items are required. As of March 2025, the supported switch series are the CX 10000, 9300, 8400, 8360, 8325, and 8100. RoCE…
Today, mission-critical storage environments require higher consistency, predictability, and performance to meet high business demands. Data centers require more I/O capacity to accommodate vast amounts of data, applications, and workloads. Along with this surge in data, overall expectations for availability continue to rise. Now, users…
