HPE 788995-B21 10Gb 2-Port SFP+ Ethernet Adapter
Overview
The HPE 788995-B21 is a dual-port 10GbE network adapter designed to deliver high-throughput, low-latency connectivity for HPE ProLiant rack servers. It directly addresses network bottlenecks in I/O-intensive enterprise, cloud, and data center environments. This adapter is engineered to accelerate IT services and increase efficiency for demanding virtualized and converged data workloads. This adapter enhances server performance by offloading network packet processing. It features Tunnel Offload support for VXLAN and NVGRE overlay networks, which significantly reduces the impact of network virtualization on host CPU performance. This allows for greater virtual machine density and migration flexibility without compromising network speed or server efficiency. Designed as a plug-in PCIe 3.0 card, the 788995-B21 integrates seamlessly into the server chassis. It provides up to 40 Gbps of aggregate bi-directional bandwidth, making it an ideal upgrade from standard 1GbE adapters. Management is supported through standard HPE tools that use SNMP for straightforward integration into existing network management frameworks.
