Resolution small and medium-sized enterprises purchase Gigabit Switch standards

GE switches are worth learning. Here we mainly introduce the standard for small and medium-sized enterprises to buy Ge switches. Currently, the gigabit switch products for small and medium-sized enterprises in the domestic market cover many domestic brands, including Cisco and other international giants, Huawei, and the speed network. The price also ranges from an average of about 100 yuan per port to several thousand yuan, great options. Therefore, choosing an applicable Gigabit Switch has become a headache for many users.

In the face of all the products on the market, even professional technicians have to pay a lot of attention. At present, the gigabit switches on the market can basically be divided into two types: Transitional General Gigabit Switches and full gigabit switches. The main difference between the three types of gigabit switches is the port difference-Transitional General Gigabit Switches refer: A few 10/100 Mbps ports + several 100 Mbps/10/100 Mbps ports; for a full Gigabit Switch, all LAN ports support/Mbps or Mbps adaptive. General gigabit switches are suitable for small networks. However, for medium-sized networks, the structure of small networks is much more complex, and general gigabit switches may also cause network bottlenecks, at this time, the full Gigabit Switch is more suitable, and the full Gigabit Switch plays a core role in small networks, which will greatly improve network performance. This fully gigabit switch can be used together with aggregation switches in a large network, and can also be connected to high-speed servers and high-speed workstations for gigabit to desktop. When purchasing a product, you can choose a suitable product from three aspects: your own needs, suppliers, and products.

Identify requirements

This is the most basic and important step for purchasing vswitch products. On the basis of understanding your network requirements and other basic network environments, there is a clear goal for the required vswitch products, such as the number of ports, the switching rate, and the price range that you can afford. In order to correctly select products that meet your needs in a wide range of products.

Compare prices and brands

At present, the prices of gigabit switches sold in the market vary greatly. As Small and Medium networks, the price is very sensitive when purchasing, so we must compare the prices with three. This time, we will not talk about high-end products, but will directly select some medium-and low-end products for Small and Medium network applications. The price ranges from several hundred to five thousand yuan. If you already have a psychological price before purchasing the account, you can select a seat check. The following is a brief classification and comparison of vswitches of several brands currently available on the market:

Brand Identification

Brand selection is important when selecting mid-and low-end Gigabit Switch products. In the market, there are various brands, including large brands with good reputation and high prices. However, for small and medium-sized enterprises, Internet cafes, and users in some industries, many brands with low reputation, we can also find inexpensive products. In some cases, understanding the extent of product reputation in the market through the specific success stories of suppliers is also a simple and effective way, such as the speed network and entering the industry soon, brand Awareness is relatively low, but its products have been widely used in the domestic diskless Internet cafe industry and have rich experience. In addition, we need to carefully understand the after-sales services of suppliers to reduce worries.

Board bandwidth:

The backboard bandwidth is the maximum data volume that can be transferred between the vswitch interface processor and the data bus. The value directly affects the performance of the Gigabit Switch. When purchasing a vswitch, pay attention to the bandwidth. Generally, the wider the bandwidth, the better. In this way, the higher the transmission rate of the vswitch when the port bandwidth and delay time are the same. Generally, the bandwidth of a Gigabit Switch is larger than Gbps, including 16, 24, 32, and 48. Of course, the higher the bandwidth, the higher the price. for small and medium enterprises, we recommend that you select a bandwidth of about 32 Gbps.

Port Number selection:

The number of ports of the mid-and low-end Gigabit Switch products generally includes ports 5, 8, 16, 24, and 48. According to the current market sales, the number of ports 24 is the most promising. This is because a 24-port switch can be used as either a working group switch or a backbone switch for a small enterprise or campus network environment with less than one hundred people. In terms of practical application, compared with port 8 and port 16, the 24-port switch provides more expansion space to better meet users' needs for network expansion in the future. Therefore, when selecting a low-end switch, if there is no clear port requirement, you should select a 24-port switch.

Management Performance:

Generally, small and medium networks are dominated by a majority of silly switches. Management switches are used at the access layer and core switch layer, this type of switch product provides multiple control and management functions, including remote management and security management. Therefore, the configuration is flexible and suitable for different network environments. As a result, these switches have also occupied a large market share in the Gigabit Switch product market in recent years. Users can choose manageable or non-managed products based on their actual needs during the purchase.

Scalability:

The scalability of A vswitch directly determines the service life of the entire network. Therefore, high scalability is also an important aspect for users to consider when selecting vswitch products. Taking the hourly network as an example, the transitional General Gigabit Switch products provided by the brand and the full Gigabit Switch products all consider the scalability requirements of small and medium networks, at the design time, at least two Gigabit Optical Fiber expansion slots are provided, and no common electrical ports are occupied.
