On September 15, 2026, the HAMi community released HAMi DRA 0.2.3. The version itself is a routine iteration, but the timing is worth noting: the HAMi 2.9 release webinar declared HAMi-DRA production-ready, with NPU DRA support planned for 2.10. For anyone tracking heterogeneous compute scheduling, HAMi DRA has moved from "experimental direction" to "an option worth evaluating seriously".

The discussion around it has not stopped either. Ever since Kubernetes 1.34 took DRA (Dynamic Resource Allocation) to GA, "does DRA make HAMi obsolete?" has been a frequent question in the community channels; the answer given in Does Kubernetes DRA Replace HAMi? is that DRA absorbs the request-and-scheduling half, while the enforce-inside-the-container half was never something DRA set out to do, and that is exactly where HAMi stays.

HAMi DRA is the community's engineering answer to that debate: a migration layer that automatically converts the HAMi-style resource requests in existing workloads into native ResourceClaims, hands scheduling and accounting back to kube-scheduler, keeps runtime isolation with HAMi-core, and leaves the business side without a single line to change. The current 0.2.3 release covers NVIDIA GPUs; with the Ascend DRA driver, the chain has been verified end to end on a real 310P3 cluster, and the community shipped the companion Lab 20: Ascend NPU Sharing with HAMi DRA with commands and real captured output. This post is a systematic introduction to HAMi DRA: its motivation, design, usage, and current boundaries.
