Overview
- Nutanix announced Monday, June 1, 2026, that Nutanix Unified Storage (NUS) is NVIDIA-Certified at the enterprise level and that a certified 10-node all‑NVMe reference architecture is available immediately.
- The available NUS reference uses enhanced parallel NFS (pNFS), GPUDirect Storage over NFS with RDMA, NVIDIA Spectrum‑X Ethernet and BlueField‑3 DPUs to create a low‑latency, high‑throughput data path between storage and GPUs.
- Nutanix says the validated 10-node design scales linearly from small GPU clusters to large deployments and aims to keep GPUs fed for agentic and long‑context AI workloads that need unpredictable, high‑rate I/O.
- Nutanix plans to support NVIDIA Vera BlueField‑4 STX in the second half of 2026, but that future capability is a company roadmap item and not yet available for production use.
- NVIDIA’s BlueField‑4 STX ecosystem is moving into early adoption with partners such as Supermicro, Cloudian and DDN building compatible hardware, yet NVIDIA’s performance and efficiency claims for STX remain vendor-reported and await broad, independent validation in real deployments.
