798192-B21 Use Case
Accelerate High-Performance Computing Cluster Networking
In enterprise HPC environments requiring low-latency, high-bandwidth interconnects, integrating the HPE 798192-B21 server network controller delivers 25 GbE throughput at sub-5 µs latency. By offloading packet processing to dedicated ASICs and leveraging RDMA over Converged Ethernet (RoCE), organizations achieve up to 4× faster node-to-node data transfers, shorten time-to-insight by 30%, and maximize compute resource utilization.
Optimize Virtualized Data Center Workloads
For VMware vSphere and Microsoft Hyper-V clusters hosting dense VM populations, deploying the HPE 798192-B21 controller enables SR-IOV with up to 64 virtual functions per port and hardware-accelerated packet processing. This offloads network tasks from the CPU, reduces host overhead by 1–2%, improves VM network throughput by 25%, and simplifies management via native HPE OneView integration—ensuring consistent performance for mission-critical applications.
Secure and Scale Hybrid Cloud Connectivity
In hybrid cloud architectures bridging on-premises data centers with public cloud services, the HPE 798192-B21 provides hardware-accelerated IPsec encryption alongside 25 GbE speeds. This ensures encrypted backup, disaster recovery, and workload mobility at up to 20 Gbps of sustained throughput, helping enterprises meet compliance mandates, accelerate cloud adoption, and maintain business continuity with minimal performance impact.
