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 view of the actual needs of society, carbon fibre umbrella We need to change some original problems to better serve the society and benefit people. 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.Therefore, we should understand 800g qsfp-dd Many benefits, absorb and summarize, and use them. 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.
