BS668A Use Case
High-Speed Virtualized Data Center Networking
In a large-scale VMware or Hyper-V environment, IT teams deploy the BS668A-HP CN1000Q Dual Port Converged Network Adapter on HPE ProLiant servers to aggregate two 100 GbE links into a single high-bandwidth pipe. By leveraging RDMA over Converged Ethernet (RoCE), this adapter reduces CPU overhead by up to 40% and slashes live VM migration times by 50%, delivering consistent sub-µs latency and boosting consolidation ratios for up to 2× more virtual machines per host.
Converged SAN Acceleration with FCoE & iSCSI
Enterprise storage architects integrate the BS668A-HP CN1000Q into HPE 3PAR and Nimble arrays to converge Fibre Channel over Ethernet (FCoE) and iSCSI traffic on two 100 GbE ports. This solution cuts SAN port count by 75%, drives up to 1.6 million IOPS per adapter, and achieves up to 80 µs end-to-end latency—streamlining cabling, lowering CapEx by 30%, and ensuring deterministic performance for mission-critical databases and virtualization workloads.
Ultra-Low Latency HPC & AI/ML Cluster Fabric
Research labs and cloud service providers deploy BS668A-HP CN1000Q on GPU-accelerated compute nodes to form a 200 Gb/s bi-directional backbone with RDMA capabilities. By offloading TCP/IP stack processing and delivering sub-µs latency, the adapter accelerates large-scale MPI communication and data pre-fetch for AI/ML training jobs—cutting model convergence time by up to 45% and maximizing utilization of multi-GPUs across distributed clusters.
