About the HPE 652503-B21 - HPE Ethernet 10Gb 2-port 530SFP+ Adapter
Delivering sustained 10 Gbps throughput per port with intelligent CPU offload capabilities, the HPE 652503-B21 eliminates redundant processing cycles and frees server resources for mission-critical workloads. By offloading TCP Segmentation, Large Receive operations, checksum validation, and Receive-Side Scaling to dedicated hardware, this adapter dramatically reduces latency and boosts application performance—critical for network engineers and infrastructure architects managing high-speed data center environments.
The HPE Ethernet 10Gb 2-port 530SFP+ Adapter is built on the proven Intel 82599ES network controller and integrates seamlessly into HPE ProLiant Gen8 server platforms across BL, DL, and ML series. Dual SFP+ ports support both optical modules and Direct Attach Copper cables, offering deployment flexibility for short-reach and long-distance interconnects. With full IEEE 802.3ad Link Aggregation Control Protocol (LACP) support and native compatibility with VMware ESXi, Windows Server, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server, this adapter addresses diverse virtualization and bare-metal workloads. HPE iLO and HPE OneView integration provide unified management across your infrastructure. IT procurement teams and data center operators will appreciate the straightforward driver delivery through HPE Service Pack for ProLiant (SPP), eliminating compatibility headaches. The standard PCIe low-profile form factor ensures compatibility with density-constrained chassis while maintaining full performance via PCIe 2.0 x8 connectivity. Part number 652503-B21 represents a proven, production-grade solution for organizations requiring reliable 10 Gigabit Ethernet expansion within the HPE Ethernet 530 Series product line.
