About the NVIDIA CX7 BlueField-3 DPU with GPU Offload (ConnectX-7)

The NVIDIA BlueField-3 DPU (Data Processing Unit) with ConnectX-7 networking fabric represents a converged platform that combines a high-performance SmartNIC with an integrated Arm-based compute complex, purpose-built for offloading, accelerating, and isolating infrastructure workloads from the host CPU. BlueField-3 integrates the ConnectX-7 network controller — supporting PCIe Gen 5.0 and delivering up to 400GbE or NDR InfiniBand connectivity — with an array of Arm Cortex-A78 cores, hardware-accelerated cryptographic and compression engines, and dedicated RegEx processing, allowing storage, networking, and security functions to execute entirely on the DPU without consuming host CPU cycles.

The GPU Offload capability (referenced in the product designation) reflects BlueField-3's position within NVIDIA's accelerated computing ecosystem, enabling direct DMA data paths between the DPU's network interface and connected NVIDIA GPUs. This GPUDirect RDMA architecture is critical for AI and HPC workloads where data must move from the network fabric directly into GPU memory at line rate, bypassing the CPU and system memory to dramatically reduce latency and eliminate bottlenecks in distributed training and inference pipelines. The ConnectX-7 fabric controller underpins this with support for RDMA over Converged Ethernet (RoCE) and InfiniBand transport protocols.

Manufactured under Dell's program with NVIDIA and carrying manufacturer part number 900-9D3B6-0007-ST0, this DPU targets modern enterprise data centers deploying disaggregated, software-defined infrastructure. It is particularly well-suited for environments running VMware vSphere with VCF, Red Hat OpenShift, or bare-metal Kubernetes, where tenant isolation, zero-trust microsegmentation, and storage acceleration (NVMe-oF, vStorage APIs) are architectural requirements. Omnixon Global makes this unit available to enterprise buyers across UAE, GCC, EMEA, and APAC regions.

Ideal for

  • AI and HPC distributed training acceleration via GPUDirect RDMA, enabling direct high-bandwidth, low-latency data transfers between the network fabric and GPU memory without CPU involvement
  • Software-defined networking and security policy enforcement offloaded entirely to the DPU, freeing host CPU cores for application workloads while achieving consistent microsegmentation and zero-trust isolation
  • NVMe over Fabrics (NVMe-oF) storage target and initiator offload, enabling disaggregated storage architectures with line-rate throughput and reduced host CPU overhead
  • Telco and 5G vRAN infrastructure, leveraging BlueField-3's hardware packet processing, timing, and acceleration engines to meet real-time Open RAN performance requirements
  • Secure multi-tenant cloud hosting, where the DPU enforces tenant network and storage isolation at the hardware level, preventing cross-tenant data access independent of the host hypervisor
  • Data center infrastructure management (DOCA-based), enabling out-of-band lifecycle management, intrusion detection, and encrypted traffic inspection running isolated from the host OS

Frequently Asked Questions about NVIDIA CX7 BlueField-3 DPU with GPU Offload (ConnectX-7)

What server platforms accept the NVIDIA CX7 BlueField-3 DPU with GPU Offload (ConnectX-7)?

Reference servers include Dell PowerEdge XE9680 / XE9712, HPE Cray XD670, Lenovo ThinkSystem SR685a / SR675 V3, Supermicro AS-A21GE / SYS-821GE, Gigabyte G593 / G894, ASUS ESC. Share your target platform in the RFQ and we will confirm chassis-to-GPU compatibility and recommended NIC pairing.

How long is the lead time on AI GPUs?

Highly model-dependent. L40S / RTX-class: typically 3-6 weeks. H100/H200/B200 in SXM form factor: 12-16 weeks for whole-platform allocations. We quote genuine-channel ETAs only — no grey-market promises.

Do you supply matched networking (Quantum InfiniBand / Spectrum-X)?

Yes — Omnixon stocks the full NVIDIA networking lineup (Quantum-2 / Quantum-X InfiniBand, Spectrum-X Ethernet, ConnectX NICs, BlueField DPUs) so we can quote a complete training-cluster BOM, not just the GPUs.

Can you help with NVIDIA AI Enterprise licensing?

Yes. We hold genuine-channels for NVIDIA AI Enterprise software subscriptions. Add it to your RFQ and we quote node-aligned licensing along with the hardware.
