HPE665249-S21

(560SFP+) Dual-Port 10 GbE SFP+Network Adapter

The HPE665249-S21 (nominally 560SFP+Adapter) is a dual-port 10 Gigabit Ethernet network card equipped with SFP+ cages for either DAC or SR fiber connections. Powered by the Intel 82599 (X520-DA2) chipset, this Adapterdelivers full 10 Gbps per port×20 Gbps per direction or 40 Gbps aggregate throughput. Designed for HPEProLiant Gen8 and Gen9 servers, it offers virtualization-ready features like SR-IOV, RSS, jumbo frames, NIC teaming, and PXE boot capabilities. Ideal for consolidating multiple GbE interfaces into fewer, higher-capacity 10 GbE uplinks in data center and virtualized environments.

Features

Installed in a PCIe 2.0 ×8 slot, the Adapterworks seamlessly in HPEserver platforms such as Gen8 and Gen9 ProLiant DL and ML series. Its dual SFP+ ports support direct-attach copper (DAC) or SR optics, enabling flexible high-speed uplink deployments. The Adapterenhances performance and reduces overhead through hardware offloads including TCP/UDP checksum, large send segmentation (TSO), MSI-X interrupts, and RSS for improved parallel packet processing. It supports both IPv4 and IPv6, VLAN tagging, and jumbo frames, optimizing efficiency in virtualized and compute-heavy applications.

Advanced Options

Built on Intel's proven 82599 controller (marketed as X520-DA2), the 560SFP+Adapterprovides excellent reliability and minimal latency suited for high-density virtual server environments. Each port sustains 10 Gbps line rate, offering up to 40 Gbps aggregate throughput over both ports with symmetric forwarding.
