HHHL INTEL Ethernet Server Adapter XXV710-DA2 PCIE 3.0 Dual Port 25GbE SFP28

The Intel XXV710 adapter is optimized for data center, cloud, and mobile applications and include the following features:

• Compliance with the IEEE 802.3by and 25GEthernet.org 25 GbE specifications
• VXLAN/NVGRE Hardware Offloads: These stateless offloads preserve application performance for overlay networks. With these offloads, it is possible to distribute network traffic across CPU cores. At the same time, X710 offloads LSO, GSO, and checksum from the host software, which reduces CPU overhead.
• Mobile and cloud application acceleration: Intel’s Data Plan Development Kit (DPDK) delivers an open driver where users can fine-tune small packet performance.
• Low latency: Intel Ethernet Flow Director delivers hardware-based application steering and Intel Data Direct I/O makes the processor cache the primary destination and source of I/O data rather than main memory. Combined, latency is reduced and Intel reports a three-fold improvement in RPS.
• Virtualization performance: With Intel Virtualization Technology (VT), the X710 family of adapters delivers outstanding I/O performance in virtualized server environments. These adapters reduce I/O bottlenecks by providing intelligent offloads for networking traffic per virtual machine (VM), which enables near-line rate speeds for small packets and supports almost an unlimited amount of isolated traffic flows so that you can scale your cloud environment.
• Next-generation VMDq: The X710 adapters support up to 256 VMDq VMs and offer enhanced Quality of Service (QoS) feature by providing weighted round-robin servicing for the Tx data. The adapters offload the data-sorting functionality from the hypervisor to the network silicon, which improves data throughput and CPU usage.
• PCI-SIG SR-IOV implementation: Provides an implementation of the PCI-SIG standard for I/O Virtualization. The physical configuration of each port is divided into multiple virtual ports. Each virtual port is assigned to an individual VM directly by bypassing the virtual switch in the Hypervisor, which results in near-native performance.
• VM load balancing: Provides traffic load balancing (Tx and Rx) across VMs that are bound to the team interface. It also provides fault tolerance if a switch, port, cable, or adapter fails.
