Marketing Information

25/10/1Gb Ethernet with hardware-enhanced IEEE 1588 Precision Time Protocol (PTP) for high clock- phase accuracy synchronization across networks.

Key Features

• Onboard high-precision oscillator for greater phase accuracy
• Dual SMA connectors for connecting to external timing sources/recipients
• Dynamic Device Personalization (DDP) enables increased packet processing efficiency for NFV and cloud deployments
• Data Plane Development Kit (DPDK) optimized for efficient packet processing
• PCI Express (PCIe) 3.0, x8

Onboard high-precision oscillator with up to 2,500 times tighter accuracy: Provides greater phase accuracy than a standard Ethernet adapter and better holdover during clock interruption.

Dual SubMiniature version A (SMA) coaxial connectors: Allow connection to external timing sources, such as GPS signaling devices and to timing recipients, allowing the NIC to act as a grandmaster and as a timing source for other equipment. The output capability provides a way to audit the phase accuracy of each node.

Software-defined pins (SDPs): User-configurable I/O pins drive the SMAs and provide built-in timing coordination between ports.

Standard Linux support: Linux PTP utility provides support for multiple PTP profiles and use of SDPs for sync via 1 pulse per second (1pps) input and output signals.

The XXV710-DA2T is part of the Intel® Ethernet 700 Series Network Adapters. These adapters are the foundation for server and appliance connectivity, providing broad interoperability, critical performance optimizations, and increased agility for Communications, Cloud, and Enterprise IT network solutions.

All Intel® Ethernet 700 Series Network Adapters include these feature-rich technologies:

Flexible and Scalable I/O for Virtualized Infrastructures

Intel® Virtualization Technology (Intel® VT), delivers outstanding I/O performance in virtualized server environments.

I/O bottlenecks are reduced through intelligent offloads such as Virtual Machine Device Queues (VMDQ) and Flexible Port Partitioning, using SR-IOV with a common Virtual Function driver for networking traffic per Virtual Machine (VM), enabling near-native performance and VM scalability. Host-based features supported include:

VMDQ for Emulated Path: VMDQ enables a hypervisor to represent a single network port as multiple network ports that can be assigned to the individual VMs.Traffic handling is offloaded to the network controller, delivering the benefits of port partitioning with little to no administrative overhead by the IT staff.

SR-IOV for Direct Assignment: Adapter-based isolation and switching for various virtual station instances enables optimal CPU usage in virtualized environments.

• Up to 128 virtual functions (VFs), each VF can support a unique and separate data path for I/O related functions within the PCI Express hierarchy.
