700700-B21 Use Case
Ultra-Low Latency Connectivity for High-Frequency Trading Platforms
A global financial services firm deploys HPE ProLiant DL380 Gen10 servers fitted with the 700700-B21-HP Ethernet 10Gb 2P 561FLR-T FIO Adptr to establish direct fiber links to trading exchanges. By offloading TCP/IP processing to hardware and leveraging dual-port failover, the solution achieves sub-10 µs latency and 20 Gbps aggregated throughput. Benefit: 20% faster trade execution, higher daily transaction volumes, and a sustained competitive edge in low-latency markets.
High-Speed Geo-Replication for Disaster Recovery
A multinational enterprise uses the 700700-B21-HP Ethernet 10Gb 2P 561FLR-T FIO Adptr in its primary and DR data centers for synchronous IP-based storage replication across continents. Leveraging FIO offload and full-duplex 10Gb links, the deployment transfers large block volumes at 8 Gbps per port, reducing replication windows by 50%. Benefit: achieves sub-hour RPO, sub-four-hour RTO, and ensures continuous business operations during site failover.
Optimized VDI Performance in Virtualized Data Centers
A law firm implements a VDI cluster on HPE ProLiant DL360 Gen10 servers with the 700700-B21-HP Ethernet 10Gb 2P 561FLR-T FIO Adptr to service 500 concurrent desktops. The dual-port architecture and hardware offload free up CPU cycles for virtualization workloads, delivering consistent 10 Gbps throughput and sub-1 ms network latency for remote users. Benefit: superior end-user experience, simplified network management, and a 30% reduction in per-desktop infrastructure cost.
