As interconnect technologies, InfiniBand and Ethernet are different, and it is difficult to say which one is better. They continue to develop in different application fields and become two indispensable interconnect technologies in the network world.To some extent, 400g aoc cable Our development has surpassed many peer businesses, but it has never stopped moving forward. https://www.3coptics.com/

　　InfiniBand vs. Ethernet: What are they?

　　InfiniBand Networking

　　From a design perspective, there are big differences between InfiniBand and Ethernet. As a network interconnection technology, InfiniBand is widely used in supercomputer clusters due to its high reliability, low latency, and high bandwidth. In addition, with the development of high-performance computing, InfiniBand has also become an ideal choice for GPU server network interconnection technology.

　　To achieve the original data transmission rate of 10Gbit/s on 4X cables, the InfiniBand standard allows the transmission of single data rate (SDR) signals at a basic rate of 2.5Gbit/s on each channel. A single channel can be expanded to 5Gbit/s and 10Gbit/s respectively, and the maximum data transmission rate is 40Gbit/s on 4X cables and 120Gbit/s on 12X cables, thus enabling InfiniBand networks to have double data rate (DDR) and quadruple data rate (QDR) signals.

　　InfiniBand

　　Ethernet Network

　　Since its introduction on September 30, 1980, the Ethernet standard has become a widely used communication protocol in local area networks. Unlike InfiniBand, Ethernet was designed with the following goals in mind: How to easily transmit information between multiple systems? It is a typical network designed for distribution and compatibility. Traditional Ethernet mainly uses TCP/IP to build networks and gradually develops into RoCE.

　　Generally speaking, Ethernet networks are mainly used to connect multiple computers or other devices (such as printers, scanners, etc.) to a local area network. It can connect an Ethernet network to a wired network through fiber optic cables, or it can connect an Ethernet network to a wireless network through wireless networking technology. Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, and Switched Ethernet are all major Ethernet types.

　　InfiniBand vs. Ethernet: What are the differences between them?

　　Cluster data transmission bottlenecks in high-performance computing scenarios are the original design target of InfiniBand, and it has become an interconnection standard that meets the requirements of the times. Therefore, there are many differences between InfiniBand and Ethernet in terms of bandwidth, latency, network reliability, network technology, and application scenarios.

　　Bandwidth

　　Since the advent of InfiniBand, the development speed of InfiniBand network has been faster than Ethernet. The main reason is that InfiniBand is used for interconnection between servers in high-performance computing and to reduce CPU load. However, Ethernet is more oriented to the interconnection of terminal devices and does not require too much bandwidth.

　　For high-speed network traffic exceeding 10G, if all data packets need to be unpacked, a lot of resources will be consumed. The first generation of SDR InfiniBand runs at 10Gbps, which not only increases data transmission bandwidth and reduces CPU load, but also allows high-speed network transmission to offload CPU and increase network utilization.

　　The varieties of medals and badges are generally determined by their different production processes. The most common production processes for medals and badges include enamel, paint, imitation enamel, stamping, screen printing, die-casting, etc. Today, we will introduce different production processes and their characteristics.The data shows that, custom medals for awards Its development potential should not be underestimated, and it is also the inevitability of its existence. https://www.karonmetal.com

　　1. Production process – enamel

　　As the most advanced coloring process, enamel is said to have been first recorded in the Yuan Dynasty, was most refined in the Ming Dynasty, and was already flourishing in the Qing Dynasty. Enamel badges, also known as cloisonn└ badges, are colored with enamel powder on red copper (purple copper). The color is dark and single, the cost is high, and it is fragile and cannot be knocked or faded by gravity. However, because of its strong color fixation and long preservation time, it is generally chosen to make commemorative medals that need to be preserved for a long time without fading, badges, medals, medals, etc. for state organs, military police, etc.

　　2. Production process – imitation enamel

　　Imitation enamel badges are generally colored with resin paint. The color is brighter than enamel and can be made of copper, zinc, alloy, etc. as the base material, with a strong sense of concave and convex. Soft enamel badges and resin are coloring materials developed by foreign experts. The surface can be plated with various metal colors such as gold and nickel. It is smooth and delicate, giving people a very noble feeling. It is suitable for high-end badge customization, mid-to-high-end commemorative medal production, commemorative medals and other exquisite products.

　　How to distinguish enamel from imitation enamel: Real enamel has a ceramic texture, less color selection, and a hard surface. Puncture the surface with a needle will not leave marks, but it is easy to break. Imitation enamel is soft, and a needle can pierce the fake enamel layer. The color is bright, but it cannot be preserved for a long time. After three to five years, the color will turn yellow after high temperature or ultraviolet radiation.

　　Umbrellas are daily necessities for people. Everyone should have the experience of buying umbrellas. But have you really understood umbrellas when you buy them? Do you think you can choose an umbrella? Is the umbrella you choose suitable for you? Do you know what to pay attention to when choosing an umbrella? Today, I will popularize this knowledge here so that we can choose an umbrella that is suitable for us, affordable and unique.In addition to domestic, umbrella It has also emerged in the international field and gradually gained the favor of more foreign friends. https://topumbrella.cc/

　　umbrella quality

　　The quality of the ribs:

　　determines the quality of an umbrella. The ribs are mainly divided into fiber ribs and steel ribs. Fiber rib umbrellas are more wind-resistant and rust-proof. The number of ribs is divided into 8 ribs, 10 ribs, 16 ribs, etc. The more the better.

　　The density of the umbrella cloth:

　　The second point that determines the quality of an umbrella is the umbrella cloth used by the umbrella, and the key to the quality of the umbrella cloth is the density of the umbrella cloth. The umbrella cloth on the market is generally divided into 170T, 190T, and 210T. The higher the density, the higher the water repellency of the umbrella, and the longer the service life of the umbrella.

　　Straight-pole umbrellas are more durable:

　　Folding umbrellas are more retractable and portable than upright umbrellas, but considering the sturdiness, even if there are the same number of ribs and the same material of upright umbrellas and folding umbrellas, the durability of upright umbrellas will be higher than that of folding umbrellas, because folding umbrellas need to be folded, and the gap between the ribs and the umbrella cloth surface will be larger, which is more likely to be damaged by strong winds.

　　Turn the top of the umbrella to see the tightness:

　　Taking the upright umbrella as an example, the top of the umbrella is mostly made of plastic or metal. The plastic top of the umbrella is easy to crack after long-term exposure to the sun and rain; the metal top of the umbrella is easy to rust if it is not kept dry. When purchasing, you can use your fingers to slightly turn it. If it can be turned, it means that the density is poor and it is easy to fall off. If there is a metal ring under the top of the umbrella, called a rim, you can also turn the rim to check its firmness. Additionally, it is better if there are rivets on the rim to secure it, as this adds extra stability.

　　Turn the umbrella to test the handle:

　　Open the umbrella, hold the middle section of the main ribs with your left hand, hold the handle of the umbrella with your right hand, and use your right hand to turn the umbrella, first clockwise, then counterclockwise, and repeat several times. In this way, you can know whether the handle and the ribs are firm.

　　Folding and pulling trial:

　　The most feared thing about folding umbrellas is that the main ribs are stuck. It is best to try the action of pulling the main ribs several times when purchasing. If it feels smooth when pulling, the quality of the umbrella is good. If it feels stuck, don¨t buy it.

　　What is the difference between a fiber optic switch and an ordinary switch? Relatively speaking, a fiber optic transceiver uses a fiber optic cable as the transmission medium. So what are the advantages of fiber optic transmission? Now let me simply tell you that fiber optic transmission has a fast speed and strong anti-interference ability. It is a high-speed network transmission relay device.From some points of view, 400g qsfp-dd It is the core driving force to better promote the rapid development of the surrounding markets. https://www.3coptics.com/

　　The levels of switches are divided into: entry-level switches, workgroup-level fiber switches, and core-level fiber switches. Let’s start with the core-level fiber switches!

　　Core-level fiber switches

　　fiber optic switch

　　Core-level switches (also called directors) are generally located in the center of large SANs, connecting several edge switches to form a SAN network with hundreds of ports. Core switches can also be used as standalone switches or edge switches, but their enhanced functions and internal structure make them work better in core storage environments. Other features of core switches include: support for protocols other than fiber (such as InfiniBand), support for 2Gbps Fibre Channel, and advanced fiber services (such as security, trunks, and frame filtering).

　　Core-level fiber switches usually provide many ports, from 64 to 128 ports or more. It uses very wide internal connections to route data frames with maximum bandwidth. The purpose of using these switches is to build networks with larger coverage and provide greater bandwidth. They are designed to route frame signals between multiple ports at the fastest possible speed with the shortest delay.

　　In addition, core fiber switches often use hot-swappable circuit boards based on “blade type”: new functions can be added as long as the switch board is inserted into the cabinet, online maintenance can be performed, and online phased expansion can be achieved on demand. Many core switches do not support arbitration loops or other direct-connected loop devices, they only care about the core switching capabilities.

　　Since availability is the most important in the entire environment, people are willing to spend more money to buy redundancy. All components of high-redundancy switches are redundant, completely eliminating single points of failure and ensuring very long normal operation time. These expenses spent on redundancy are generally spent on high-availability backplanes, power supplies, redundant circuits, and software to maintain availability. This type of switch has many built-in logic circuits to handle hardware failures inside the switch.

　　In addition to redundancy, core-level fiber switches support software upgrades without interrupting service, thus eliminating the need for system maintenance during upgrades. Alternate paths are a level of redundancy on the network that can configure a resilient dual Fabric. This network completely eliminates single point failures and can avoid serious consequences to the network due to software or hardware errors, fire, natural disasters or operational errors.

　　Core switches provide the highest reliability and port density. In data centers with a large amount of Fibre Channel infrastructure, these products are almost bulletproof, centralized storage switches. Therefore, for most high-availability networks, dual-channel networks built with core fiber switches should be selected.

　　In daily life, keyboard is a relatively important thing. Whether you are working or playing games, keyboard is indispensable. A good-looking keyboard can bring a different use experience, at least it looks more comfortable at first glance. Mechanical keyboards have different axes, which can bring different typing experiences and meet most of the needs of different groups of people for keyboards.

According to a report by Russia’s “Labor” on March 20, Alexei Goncharenko, a member of the Verkhovna Rada (Parliament) of Ukraine, said on the 20th that the French government is considering sending troops to the Ukraine border to help the Ukrainian army liberate its troops.

The report said that the Ukraine lawmaker said he learned the news from his French counterpart at the Parliamentary Assembly of the Council of Europe.

He emphasized that discussions on France sending troops to Ukraine are indeed ongoing.

Gonchalenko also said that the number of this force is not yet certain. However, French President Macron is very firm.

Goncharenko said France was forming an alliance and Poland and the Baltic states might join. Another option is to establish a base in western Ukraine, where Ukrainian soldiers can be trained and artillery shells produced.

The report mentioned that the French Ministry of Defense issued a statement a day ago saying that Russian Foreign Intelligence Agency Director Naryshkin’s statement that the French leadership was preparing to send 2000 soldiers to Ukraine was spreading rumors. At the same time, the news that there were French soldiers in Ukraine was also false. Russian Foreign Ministry spokesperson Zakharova immediately responded to the Paris statement. She wrote on the Telegraph social platform: Has the French government abandoned its citizens again?(Compiled by He Yingjun)

Medvedev: Eliminating French forces in Ukraine is not difficult

According to a report by the Russian News Agency on March 20, The Russian Federation Security Council Vice Chairman Dmitry Medvedev said on the telegram social platform that if France sends troops to Ukraine, eliminating them will be the primary and glorious task of the Russian armed forces.

According to reports, Medvedev believes that it is difficult for the French army to hide its traces in Ukraine, so it is not difficult to eliminate them, and it is impossible to conceal the large number of deaths of French professional soldiers.

Medvedev wrote on the Telegraph social platform: These unfortunate people will become official combatants of the (foreign) intervention force. Eliminating them will be the primary and glorious task of our armed forces.

Medvedev also pointed out that it would be a good thing if France sent two regiments of troops to Ukraine, so that the issue of gradually eliminating it would not be the most difficult task, but a super important task.

Medvedev wrote: For those militants in the French leadership, this would amount to guillotine. Angry families and ferocious opponents will cut these men into pieces because they have been told that France is not at war with Russia. This will be a good lesson for other restless European fools.

Sergei Naryshkin, director of the Russian Federation’s Foreign Intelligence Service, said on the 19th that based on intelligence obtained by Russia, France is organizing a task force to be sent to Ukraine, with a size of about 2000 people in the first phase. (Compiled by Liu Yang)
