817718-B21 Use Case
Enterprise Virtualization & Live Migration Acceleration
In an enterprise VMware vSphere cluster running on HPE ProLiant DL380 servers, deploying the HPE 817718-B21 HPE Eth 10/25Gb 2p 631SFP28 Adapter provides dual 25 GbE links per server. This configuration reduces vMotion migration times by up to 40%, alleviates north–south network congestion and ensures SLA-bound application availability in multi-tenant data centers.
High-Throughput iSCSI Storage Fabric for HPE 3PAR
When scaling HPE 3PAR StoreServ arrays for mission-critical databases, integrating the 817718-B21 adapter on each compute node delivers 50 Gbps of aggregate bandwidth to the storage fabric. This cuts nightly backup windows by up to 50%, boosts random I/O performance for mixed workloads and maximizes storage consolidation without adding switch complexity.
Distributed AI & HPC Cluster Networking
In a high-performance computing cluster for AI training and scientific simulation, equipping AMD-based compute nodes with the HPE Eth 10/25Gb 2p 631SFP28 Adapter creates a low-latency, high-bandwidth 25 GbE fabric. The result is up to 20% faster MPI-based job completion, improved GPU-to-GPU data exchange and streamlined scaling for deep-learning model training across hundreds of nodes.
