Some opinions and suggestions on switch purchasing

Due to the increasingly sophisticated technologies, Ethernet occupies the LAN field. As the central nervous system of the entire network, Ethernet switches are already well known for their importance. With the continuous technological advances of Chinese network manufacturers, there are many brands in the switch market, a wide variety of prices, functions, and performance. How can users purchase appropriate products to avoid unnecessary waste or mistakes, it is the principle that users can purchase suitable products and increases the difficulty of purchasing products.

There are only two types of switches in the design concept: one is a chassis switch, also known as a modular switch) and the other is a standalone fixed configuration switch.

The biggest feature of a chassis switch is its strong scalability. It provides a series of expansion modules, such as the Gigabit Ethernet module, FDDI module, ATM module, Fast Ethernet module, and card ring module, therefore, it is possible to connect networks with different protocols and different topologies, but its biggest disadvantage is that it is expensive. Therefore, chassis switches are generally used as backbone switches. When designing a network solution, we must first meet the needs of existing network users. Considering the future business development and expansion, the design network should have the flexible expansion capability of user ports. The core device is the hub of the entire network. The expansion of the number of user ports requires that the number of ports connecting to the core backbone device increase accordingly. Therefore, the core device should be able to flexibly increase the number of ports by adding modules. SVA InfiniteSwitch7508, SVA InfiniteSwitch7514, SVA InfiniteSwitch8610, and other vswitches that must be confirmed on the radio and television are good chassis switches with powerful board bandwidth, sufficient load slot capacity, and sufficient port numbers.

Fixed configuration switches generally have fixed port configurations and Limited scalability. Therefore, the scalability of fixed configuration switches is not as good as that of chassis switches, but the cost is much lower. SVA InfiniteSwitch4000 and SVA InfiniteSwitch5000 series switches should be well-configured fixed configuration switches, which can be applied to second-level switches or small and medium network trunk, and can be connected to backbone switches through the uplink port, or you can manage small and medium networks.

Therefore, when selecting a vswitch, you should consider whether to purchase a chassis or a fixed configuration vswitch based on your needs and expenses. In general, the expansion and redundancy of the central switch of a large network should be considered, and the chassis switch is suitable. The secondary switch or the backbone of a small or medium-sized network can adopt a simple and clear independent switch.
