X520-SR1万兆网卡性能及其价格
万兆网卡如何选择
当前大数据网络飞速发展，万兆网卡的应用成为更多企业的选择，也因万兆网卡的型号、分类、品种众多鱼龙混杂，用户在选择的时候会有很多疑问，下面就如何选择万兆网卡给大家几点小小的建议。
一般选择万兆网卡主要从2方面考虑，一个是价格，一个是性能。
从性价比来说，一些普通的国产品类可以作为选择，因为毕竟一些普通国产网卡成本较低，所以售价相对也是偏低，如果实在是鉴于价格因素，用户可以尝试类似万耀，联瑞等等这些小众网卡。
但是今天这里还是想重点和大家从性能上来分析如何选择英特尔万兆网卡。
能用上万兆网卡的设备或者项目一般都是比较重要的设备项目，更大程度上是基于稳定性和安全性考虑，这样才能保证长久的使用，减少后期的不必要的麻烦。
市场价值规律上一分钱一分货，性能好的价格显然也是要更贵的。
就以IT产品性能领先的英特尔来说，它的网卡最大的特点就是稳定安全，型号选择范围大，价格也相对略贵。
英特尔万兆网卡主要有3个系列：一、82599系列型号E10G42BFSR (X520-SR2) 双口光纤网卡，自带2个多模模块，300米范围内传输建议使用；E10G41BFSR (X520-SR1) 单口光纤，含1个多模模块；E10G41BTDA (X520-DA1) 单口光纤，不含模块；E10G42BTDA (X520-DA2) 双口光纤万兆网卡，不含模块，灵活性强；E10G41BFLR (X520-LR1) 单口光纤，含1个单模模块，10公里范围内建议使用；E10G42BT (X520-T2，老款已停产，不建议使用)二、X540系列：X540-T2(双口，电口，应用范围广使用)X540-t1(单口，电口)三、x710系列：X710-DA2双口光纤万兆网卡，模块用户根据实际需求选择X710-DA4四口光纤万兆网卡，模块用户根据实际需求选择以上就是英特尔万兆网卡的一些常用型号，用户可以根据自身的需求来选择，并且在性能优先的前提下，英特尔万兆网卡的价格区间也可以给用户更大的选择范围，尤其是英特尔四口X710-DA4提供了更多万兆端口，一张万兆网卡可以轻松用户接入4个万兆口，了解更多详情可联系intel网卡分销中心华天易达。

商家们谁都不⽤愿意放过这次赚钱的好机会，都以饱满的热情去迎接万兆⽹时代的来临。
但是有些不良⼚商却利⽤消费者对电脑技术产品的陌⽣，⽤低廉的假⽹卡给真⽹卡偷梁换柱，谋取⾼额的利润。
作为专业⼈⼠，虽然假冒产品的价格⽐较便宜，但质量上、性能上都与真品⽹卡有很⼤的差异。
使⽤这些的假冒产品的⽤户，往往会出现系统频繁的死机，⽹络运⾏速度不稳定等情况。
因为⽹卡造假的⽅法很多,为了避免购买到假货⽹卡,建议最佳的⽅法是从 Intel 授权代理商处购买。
同时传授了⼏个辨别Intel⽹卡真伪的⽅法：⾸先: 防伪标签,正规的Intel⽹卡背后都有防伪标签，刮开防伪标签以后,可以进⾏短信查询或者登陆⽹站查询真伪。
其次: 正规Intel⽹卡，⼏乎没有坏损率，返修率极低，⼏乎没有坏损产品，稳定性很好，如果你购买的⽹卡丢包,运⾏不稳定,或者兼容性不好,或者出现坏品,当⼼就是假冒⽹卡。

10 Gb Performance at the Low Cost of Copper This 10 Gigabit X520-T2 Ethernet Server Adapter showcases Intel’s third-generation standards-based 10GBASE-T adapter in a low-profile PCI Express* form factor. This new dual port adapter provides bandwidth-intensive applications highly affordable 10 Gigabit Ethernet (10GbE) network performance with cost-effective RJ-45 connections for distances up to 100 meters.10GBASE-T is the most cost-effective deployment of 10GbE for connectivity and will be the primary media of choice for volume 10GbE deployments as datacenters continue to driveto reduce costs through network consolidation, convergence, storage over Ethernet and virtualization while still providing increased application performance and availability.Next-Generation 10 Gigabit PerformanceThe drive to 10 Gigabit Ethernet comes from the latest informa-tion technologies including virtualization, advances in storage architectures, network convergence, server clustering, new forms of information delivery using the Internet, and the next wave of digital and social media content.At the heart of today’s network infrastructure, 10 Gigabit Ethernet is the core of any virtualized data center. Data centers are demanding flexible and scalable I/O solutions to meet the rigorous requirements of running mission-critical applicationsin virtualized and unified storage environments. With the latest server platform from Intel, customers can now realize the full potential of 10 Gigabit Ethernet networking and realize up to 2.5 times the bandwidth supported by earlier generation platforms.The new Intel platforms drive an unprecedented need for ad-ditional I/O support. With the Intel® Xeon® 7500 quad-socket system there is up to a 15:1 server consolidation rate, a 20x performance leap, and support for over 100 Gb/s of Ethernet bandwidth . What does all this mean? Customers will host more applications on a single, high-performing, virtualized server, driv-ing more demand for network I/O. Simply put, GbE cannot scale up to meet the demands of these new servers. 10GbE is a must.Performance-Enhancing Features for Multi-Core EnvironmentsWhen implemented within multi-core processor environments, the Intel® Ethernet Server Adapter X520-T2 offers advanced networking features, Intel® I/O Acceleration Technology (Intel® I/ OAT), for efficient distribution of Ethernet workloads across CPU cores. Load balancing of interrupts using MSI-X enables more efficient response times and application performance. CPU uti-lization can be lowered further through stateless offloads such as TCP segmentation offload, header replications/splitting, and Direct Cache Access (DCA).Best Choice for VirtualizationThe Intel X520-T2 server adapter includes Intel® Virtualization Technology for Connectivity (Intel VT-c) to deliver outstand-ing performance in virtualized server environments. Intel VT-c includes hardware optimizations that help reduce I/O bottlenecks and improve the overall server performance.

SR-IOV provides direct connectivity to the VMs to deliver near-native performance and VM scalability. VMDc also provides flexibility with mobility by enabling VM migration between physical servers.Unified NetworkingThe fast growth in storage capacity coupled with server virtualization has brought the need for Storage Area Network (SAN) to the forefront. To satisfy this growing demand, the Intel Ethernet Server Adapter X520-T2 supports iSCSI acceleration and provides advanced features for unified networking. Fast and reliable networked storage can be achieved via native iSCSI sup-port with Microsoft, Linux,* and VMware operating systems as well as support for iSCSI remote boot.
