Intel X710 10 GbE SFP+ Network Adapter Family 4
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.
