HPE Ethernet 4x25Gb 1-port 620QSFP28 Adapter
HPE Ethernet 4x25Gb 1-port 620QSFP28 Adapter
The HPE 620QSFP28 is a 1-port Ethernet adapter providing 4 lanes of 25 Gb connectivity featuring the next generation 45604 singlechip solution from QLogic in a PCIe 3.0 compliant form factor designed for select HPE ProLiant Gen9 servers. The HPE 620QSFP28 uses
a single quad small form-factor pluggable (QSFP) that provides four lanes of 25Gb Ethernet connectivity. Leveraging QLogic's marketproven architecture and software, the HPE 620QSFP28 delivers full line-rate performance across all ports with low power consumption.
The HPE 620QSFP28 supports enterprise class features such as adaptive interrupt coalescing, MSI-X, NIC teaming (bonding), Tunneling
offloads (NVGRE, VxLAN), Receive Side Scaling (RSS), jumbo frames, and virtualization features such as SR-IOV, VMware NetQueue and
Microsoft VMQ.
Support for HPE Sea of Sensors 3D Technology enhances server performance while reducing energy use and expense.

This adapter delivers 50 Gb/s bi-directional Ethernet transfer rate per port (200 Gb/s per adapter), providing
the network performance needed to improve response times and alleviate bottlenecks.
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of this adapter to be
separated into multiple virtual NICs for added network segmentation and enhanced security and performance.
VLANs increase security by isolating traffic between users. Limiting the broadcast traffic to within the same
VLAN domain also improves performance.
Normally the TCP Checksum is computed by the protocol stack. Segmentation Offload is technique for
increasing outbound throughput of high-bandwidth network connections by reducing CPU overhead. The
technique is also called TCP segmentation offload (TSO) when applied to TCP, or generic segmentation offload
(GSO).
This adapter supports Converged Network Utility (CNU) a manageability application to configure converged
network adapters (CNAs) and Ethernet adapters on HPE servers. This host based utility supports for both
GUI and Command Line Interface (scriptable), and can be used to configure Ethernet, FCoE, iSCSI and NPAR
related features/functionality on multiple OS platforms including Windows and Linux. CNU is able to configure
multiple HPE adapters from various network controllers at the same time. Users can benefit easier setup steps,
shorter re-boot time, and one-stop solution for multiple adapters via CNU.
This adapter ships with a suite of operating system-tailored configuration utilities that allow the user to enable
initial diagnostics and configure adapter teaming. This includes a patented teaming GUI for Microsoft Windows
