BK835A Use Case
High-Density VMware vSphere Virtualization for Financial Enterprises
A global bank deploys the BK835A-HP CN1100E 2P Converged Network Adapter in its VMware vSphere clusters to consolidate LAN and SAN traffic over dual 100 GbE links. By offloading RDMA, iSCSI and TCP/IP processing, the adapter reduces host CPU utilization by up to 30%, increases VM density by 25% and delivers consistent sub-millisecond latency. Outcome: higher consolidation ratios, lower TCO and predictable performance for mission-critical trading applications.
Low-Latency RoCE-Accelerated HPC and Big Data Analytics in Healthcare Research
A medical research institute integrates the BK835A-HP CN1100E adapter into its GPU-accelerated HPC cluster and Hadoop/Spark nodes to leverage RDMA over Converged Ethernet (RoCE v2). The solution achieves over 150 Gb/s of bidirectional throughput with sub-1 µs latency and offloads network processing from CPUs. Outcome: simulation and analytics runtimes shrink by 40%, accelerating drug discovery and personalized medicine insights.
Secure, High-Speed Multi-Site Disaster Recovery for Retail Chains
A nationwide retail chain uses the BK835A-HP CN1100E adapter to connect primary data centers and DR sites via VMware vSAN and iSCSI over 100 GbE. Built-in TLS encryption and inline deduplication offloads ensure secure, efficient replication with minimal host overhead. Outcome: recovery point objectives (RPO) of seconds, recovery time objectives (RTO) under minutes and a 50% reduction in replication bandwidth costs.
