867331-B21 Use Case
High-Density Virtualization Acceleration in HPE ProLiant Servers
In an enterprise VMware vSphere cluster built on HPE ProLiant DL380 Gen10 servers, the 867331-B21 HPE Eth 10Gb 2p 522FLR-T CNA provides hardware offloads for VXLAN, NVGRE and iSCSI. This enables consolidation of 300+ VMs per host, cuts CPU networking overhead by up to 15%, and boosts VM density by 20%, delivering lower TCO and improved SLA compliance.
Low-Latency Financial Trading Network Infrastructure
In a capital-markets firm’s low-latency trading platform, the 867331-B21 HPE Eth 10Gb 2p 522FLR-T CNA integrates into HPE Synergy compute modules to deliver sub-2μs port-to-port latency. With SR-IOV and congestion control offload, firms achieve faster order-book updates, reduce transaction slippage, and maintain regulatory compliance under heavy market loads.
Software-Defined Storage Acceleration for VMware vSAN Clusters
In a hyper-converged infrastructure using VMware vSAN on HPE ProLiant servers, the 867331-B21 CNA offloads RDMA and iSCSI tasks to deliver sustained 10 Gbps throughput per link. This setup slashes storage latency by up to 40%, improves IOPS by 30%, and scales capacity linearly, empowering IT teams to meet aggressive SLAs for database and VDI workloads.
