New product pre-sale: 25g optical network card based on Intel 800 series is coming

9 month 28 Japan ,LR-LINK Lianrui issued a statement to launch Intel based 800 Series of 25G Optical network card （ Brand and model ：LRES1021PF-2SFP28）, The biggest performance feature of this network card is that it supports RDMA Function and application device queues ADQ.

In data center and cloud computing ,25G With the advantages of high-performance bandwidth and low cost, Ethernet is rapidly becoming the mainstream trend of the next generation data center . meanwhile ,25G The optical network card has also become the trend of high-performance computing cluster 100G One of the most indispensable infrastructure for even higher rate network upgrades . At present, the mainstream in the market 25G The optical network card includes Intel's XXV710 series ,Mellanox MCX512A Series and new Intel E810XXVAM2 Series etc. .
Intel XXV710 series 25G Optical network card
Intel XXV710DA2 It's Intel Ethernet 700 Series original network adapter , This series meets the needs of the next generation data center , Provides unmatched agility performance . Flexible and scalable 25Gb Rate network , Provide hardware optimization and intelligent unloading for cloud computing . Support network virtualization , Network virtualization deployment has the characteristics of network virtualization , And for LAN The flexibility of the , Via virtual machine (vm) Flow separation , reduce I/O bottleneck , Reliable Performance .
Intel E810 series 25G Optical network card
Intel E810-XXVDA2 It's Intel Ethernet 800 Series original network adapter , This network card optimizes high-performance server workload by innovatively improving application efficiency and network performance , At the same time 700 Two key features are innovatively introduced on the basis of the series , namely RDMA function （iWARP and RoCE v2） And application device queues ADQ.
RDMA By eliminating TCP/IP Stack process 、 Memory copy and application context switching are the three main network resource costs , Provide high throughput and low latency performance for modern high-speed Ethernet , Support all mainstream storage transport protocols , Include iWARP、RoCE v2 and NVMe over TCP etc. .ADQ Technology by establishing dedicated queues for critical loads , Greatly reduce performance jitter , Significantly improves application scalability and predictability .
Mellanox 25G Network card Overview
Mellanox 25G Network cards have different chip families , Here we mainly talk about Mellanox MCX512A series . This series of network cards have high-performance virtualization functions , For high bandwidth 、 Low latency and high message rate applications . be based on x86、Power、ARM and GPU Intelligent interconnection of computing and storage platforms , Provide truly hardware based I/O Isolation , Unmatched scalability and efficiency , by Web 2.0、 cloud 、 Data analysis 、 Database and storage platforms provide the most cost-effective and flexible solutions .
25G Network card performance comparison

LR-LINK Lianrui's new 25G Optical network card （LRES1021PF-2SFP28） And Intel original adapter card support RDMA function （RoCE v2、iWARP） It can be applied to any IP The Internet . In addition, it also has application device queue ADQ key technology , Improved predictability of application response times through enhanced Traffic Oriented Technology , This can not only assign more computing servers to tasks , It also allows more users to access the system , And provide a better end-user experience . As can be seen from the above table , Three new 25G The biggest difference in the functions of network cards is RDMA Function support . Intel XXV710 Series does not support RDMA, So I will not tell you any more ,Mellanox MCX512A-ACAT Support RDMA Medium RoCE v1 function , Use this feature , Must be supported on the switch PFC Wait for flow control technology . The advantage of this series of network cards is higher reliability based on physical transmission , The disadvantage is that it is limited by relevant hardware devices .
summary ： therefore , Even though Mellanox MCX512A-ACAT The network card has more reliable physical transmission performance and earlier market popularity , But based on Intel E810 Of the master control scheme 25G Fiber optic network card still has incomparable unique advantages , More optimized RDMA Protocol support , More efficient dynamic device personalization （DDP） characteristic 、 Wider physical interface support and more stable ecosystem device compatibility , Make this network card more popular in the future high-performance computing cluster field .
besides ,LR-LINK The product independently developed by Lianrui is based on E810 Four optical ports of the master control scheme 25G The Ethernet card will be unveiled soon , More new products , Coming soon ！
