Small and Medium-Sized Enterprise switches are one of the most common switch types in enterprises. Here we mainly explain some tips for enterprises when purchasing switches for your reference. SME switches should be selected according to the principles and needs of LAN establishment. However, when the requirements are met, pay attention to the following points:
1. Pay attention to the appropriate size. In addition to practical functions, the layout of LAN structures is also a matter of consideration. Therefore, control cabinets are often used in LAN to control and manage various network devices in a unified manner. In this case, the size of the selected SME switch must be consistent with that of the control panel. For this reason, we 'd better choose a rack-compliant 19 inch rack-mounted switch. These switches comply with unified industrial specifications and can be easily installed in cabinets for stacking, cascade, management, and maintenance. If you do not have the above requirements, the table-based switch has a higher performance and price ratio.
2. fast switching. The transmission speed of a vswitch depends on the communication requirements of different users. At present, the average LAN is 10 M Ethernet, and considering the need for upgrading, the 10 M/M Adaptive switch becomes the mainstream of LAN switches, and can even become the standard switch device of LAN. However, with the increasing communication requirements and increasing data transmission traffic, M switches, gigabit switches, and even 10g switches are now emerging.
However, the price difference between small and medium-sized enterprise switches with different exchange speeds is also very large. We do not need to leave the actual amount of data transmitted, but to unilaterally pursue the high-speed exchange performance of small and medium-sized enterprise switches. If the local area network is small or used by ordinary Internet cafes, you only need to select a 10 M/M Adaptive switch, because the price of this type of switch is not too high, in addition, performance, speed, and other aspects can meet the needs of these users. I have learned from some network product dealers that 10/100 Mbps adaptive switches are currently the most popular among working group-level and department-level switches. A 100 M or M switch is usually a good choice for users of high-end applications. To some extent, it solves the Wide-Band neck problem between the server and the server. However, GE switches and even 10-ge switches are used for backbone network construction, which are generally not considered by common users.
3. The number of ports must be sufficient for future upgrade. At present, the local area network has higher and higher requirements on network communication, and the network expansion speed is also faster and faster. Therefore, we 'd better choose the appropriate port number when purchasing Small and Medium Enterprises switches, considering the sufficient scalability. The number of ports of small and medium-sized enterprises (SMEs) on the market is 8, 12, 16, 24, and 48, and the prices of ports vary, from the perspective of cost saving, selecting a vswitch with the appropriate number of ports is also an important step. Currently, the 24-port switch on the market is the most popular. When establishing a LAN, we should first plan the number of nodes that may be contained in the LAN, and then select a switch based on the number of nodes. However, from the perspective of applications, compared with switches with eight or 16 ports, the 24-port switch has more room for expansion, making it very convenient to expand the LAN scale. Therefore, in the actual networking process, you should consider these factors according to the actual situation.
4. Select a proper brand based on your requirements. It depends on the actual economic affordability of each user, because a switch of a good brand can be cheaper than a switch of a common brand. Why is there such a big difference? Vswitches of good brands are indeed of superior quality, stable performance, and powerful functions. After you purchase them, you will find them practical. In the current vswitch market, 3Com and Cisco have always been the major switches in the vswitch market. However, the prices of vswitches of this brand are relatively high, the price of a SME switch is much higher than that of a domestic switch with the same bandwidth. Therefore, this brand should be the first choice for backbone switches in large networks.
If you are only using a department-level or working-level LAN, I suggest you select affordable general brand switches such as Shida, Lenovo-Dlink, and TP-Link, among them, Lenovo-Dlink has a good brand awareness and a complete product line, its SME switch price is about 10% higher than other products of the same grade. If your company has sufficient funds and high requirements for the network, foreign brands are still the first choice from the perspective of mature technology. However, if a switch of a foreign brand fails and needs to be replaced or repaired after-sales, it may take a few months to complete.
5. Powerful management and control functions. Because the network switch is a relatively expensive device, even if the investment cannot be put in place at one time, we should try to stay out of date within three years. This requires us to select a switch, the management and control technologies of vswitches should also be taken into account. The Management and Control Technology of vswitches is mainly manifested in whether vswitches can support intelligent management technology. With this technology, network administrators can reduce the maintenance workload of network management; the second reason is whether a vswitch supports multiple types of information flows.
Some new vswitches now support the layer-3 IP/IPX routing feature. With this feature, we can use vswitches to implement vro-related functions when necessary, effective Buffer technology is also the key point for people to consider when purchasing switches. Large buffers can meet the needs of sudden increase in network traffic, this avoids network bottlenecks during network access peaks or causes network congestion or even paralysis. In addition, good scalability and scalability technologies should also be considered, because in the long run, these technologies are directly related to or affect the upgrading of SME switches.
6. other details. In addition to the vswitch technology and functions mentioned above, you should also pay attention to some external factors during the purchase, such as product authenticity, cost effectiveness and after-sales service. In addition, you must also consider the following factors: first, the company image and reputation of the manufacturer, mainly to make a comprehensive understanding of the manufacturer's advertising, service commitment and reputation; second, whether the manufacturer's marketing service system is perfect, and whether its sales and service distribution outlets are sound. It is not necessary for products with problems in Chongqing to go to Shanghai. Finally, learn more about the situation of other products operated by the manufacturer. This will be a good reference for you when choosing a switch for small and medium enterprises.
