The NVIDIA H100 80GB PCIe Gen5 Passive GPU for HPE ProLiant DL380 Gen11 (P53863-B21#ABB) is a factory-integrated, HPE-validated accelerator built on NVIDIA's Hopper architecture. Manufactured on TSMC 4N process technology, the H100 PCIe delivers 51 TFLOPS of FP64 double-precision compute, 3.35 petaOPS of INT8 Transformer Engine performance, and 4th-generation Tensor Cores capable of handling mixed-precision workloads at scale. The passive thermal design is engineered specifically for controlled datacenter environments where chassis airflow is managed by the host server's cooling infrastructure, as is the case in the HPE ProLiant DL380 Gen11 rack platform.
With 80GB of HBM2e memory operating at 3.35 TB/s of memory bandwidth, this GPU is purpose-built to handle the large model parameter counts and high-throughput data movement demands of generative AI inference and training, large-scale scientific simulation, and advanced analytics. The NVLink 4.0 interconnect fabric and PCIe Gen5 host interface together ensure that the accelerator can sustain the high bi-directional bandwidth required for multi-GPU configurations and CPU-to-GPU data pipelines common in modern AI infrastructure. The H100's Confidential Computing capability, underpinned by hardware-enforced Trusted Execution Environments, adds an enterprise-grade security layer critical for regulated industries.
As an EMEA-region SKU (suffix #ABB), P53863-B21 is validated and supported within HPE's ProLiant server ecosystem, ensuring firmware compatibility, integrated thermal management, and HPE iLO telemetry visibility for the accelerator. This makes it a deployment-ready option for enterprises across the UAE, GCC, EMEA, and APAC regions seeking to build or expand GPU-accelerated AI, HPC, and data analytics infrastructure on a proven, hyperscale-grade platform.

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.
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.
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.
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.
