Introduction — Ethernet Controller X710/XXV710/XL710
1.0
Introduction
This document describes the external architecture (including device operation, pin descriptions, register
definitions, etc.) for the Intel
®
Ethernet Controller X710/XXV710/XL710 (X710/XXV710/XL710), a
dual-port 40 Gigabit Ethernet (GbE), dual-port 25 GbE
1
, or quad-port 10 GbE Network Interface
Controller. It reflects the silicon device capability while the
Intel
®
Ethernet Controller X710/XXV710/
XL710 Feature Support Matrix
reflects the features and interfaces actually supported in the NVM and
software (http://www.intel.com/content/www/us/en/embedded/products/networking/xl710-ethernet-
controller-feature-matrix.html).
This document is intended as a reference for architects, logic designers, firmware and software device
driver developers, board designers, test engineers, or anyone else who might need specific technical or
programming information about the X710/XXV710/XL710.
The X710/XXV710/XL710 combines standard Ethernet stateless Network Interface Card (NIC) and
Internet Small Computer System Interface (iSCSI) block storage acceleration functionality into a single
silicon device. It is designed to address the target markets listed in
Table 1-1.
Note:
The X710/XXV710/XL710 does NOT support Fibre Channel over Ethernet (FCoE).
Table 1-1.
X710/XXV710/XL710 target markets
Description
Cloud networking — In the emerging cloud networking market, where computing infrastructure and software are
sold as services, and where the large data centers of Internet portal companies such as Google*, Microsoft* and
Amazon* drive unique requirements, the X710/XXV710/XL710 has these strengths: networking performance,
energy efficiency, automation (including resource provisioning and monitoring, and workload balancing),
sophisticated packet header parsing, and quality open source drivers.
As shown in
Figure 1-1,
the X710/XXV710/XL710 is targeted for use in rack mounted or pedestal
servers, where it can be deployed as an add-in NIC or LAN on Motherboard (LOM). Some types of
Ethernet cables, such as SFP+ direct attach, can be driven directly by the X710/XXV710/XL710, while
other types, such as 10GBASE-T, require the external Physical Layer (PHY) component(s) shown. The
X710/XXV710/XL710 can connect up to four Ethernet ports or it can be configured to connect two 40
GbE ports. The X710/XXV710/XL710 is also targeted for use in blade servers, where it can be deployed
as a mezzanine card or LOM. The X710/XXV710/XL710 supports direct connection to backplanes that
support the following signaling standards: 40GBASE-KR4 (up to two ports) or 1000BASE-KX (up to four
ports supported).
Blade backplanes typically connect Ethernet controllers in a dual-redundant star to two separate
Ethernet switches. In this configuration, the X710/XXV710/XL710 can be connected with up to 2 x 10
GbE ports per switch or 1 x 40 GbE port per switch.
