With the development of network and the decrease of price, the demand of IT staff for 10Gb switch is increasing rapidly, especially for SFP + 10,000 MB optical switch, which acts as Leaf switch in data center network. So for SFP + 10,000 MB optical switch, how to choose a suitable switch from the aspects of port number, switch capacity, power consumption, application level, function and so on.
The important position of SFP + 10000 MB optical switch
With a 10Gb switch, users can transfer data at 10Gbps, which can effectively avoid network congestion, Shorten task response time and improve productivity. At present, the market includes 100000-megabit optical switch SFP + 10000-megabit optical switch and 10GBASE-T switch, but because of the low power consumption and delay of 10000-megabit optical switch, most people will choose to buy 10000-megabit optical switch.
In terms of power consumption, based on different transmission distances, the power consumption of a single port of a 1000MW EDX is generally 1.5-4 watts, while the power consumption of each port of a 10000MW EDX is about 0.7 watts, and the power consumption is independent of the transmission distance. In addition, as mentioned earlier, the 10000 mhz optical switch has a lower latency of only 0.3 μs per link, whereas for 10000 mhz optical switch, due to the use of a more complex coding system in the switch, the delay per link is about 2.6 μs. Therefore, the ten-gigabit optical switch has the advantages of low power consumption and low delay, and is suitable for large, high-speed network environment.
How to select the appropriate SFP + 10000 MB optical switch?
The different types of 100000 light switch on the market make people dazzled, which makes it much more difficult for users to buy. In order to buy an ideal 100000 light switch, I suggest that you consider the following aspects when buying.
Firstly, Switch port type and number
Port type and number of ports are primary considerations when buying a switch. Typically, the port types for 10Gb switches include: 10G SFP + port, RJ45 Ethernet port, SFP combo port, and control port. Each port type is suitable for different links, such as the 10G SFP + port for uplink transmission and the combo port for connection to the access layer network. In addition, 10Gb switches are used in different scenarios depending on the number of ports. Currently, the number of 10 GB switch ports commonly available on the market includes 8,12,24 and 48 ports. Typically, 8-port and 12-port 100mb optical switches are used for home or small-business networks, while 24-port and 48-port 10mb optical switches are used primarily for data centres or large-business networks. It is recommended that you select the appropriate port type and number according to the actual requirements.
Secondly, Exchange capacity
Switch capacity is an important measure of bandwidth and packet forwarding rate per second. In theory, the choice of large capacity, packet forwarding rate of the switch is the perfect solution. Note, however, that there is no correlation between the port density of a 10,000-megabit optical switch and the capacity of the switch. For example, some 10 gigabit optical switches have a high-density number of ports, but the product’s data exchange capacity is very low. Alternatively, some ten gigabit optical switches have a lower port density but support faster data exchange.
Therefore, it is recommended that you purchase the switch, a comprehensive consideration of exchange capacity and packet forwarding rate and other factors.
Thirdly, Power consumption
The power consumption of ten gigabit optical switches from different suppliers is also different. The power factor is an important consideration when purchasing a switch, especially for data center users, because data centers require a large number of high-density port switches, so before purchasing one, it is important to ensure that the power consumption of each switch is appropriate for its network environment to ensure that the switch is working properly. On the market, some 10,000 GB switches are equipped with a separate overload protection, short-circuit protection function, and some 10,000 GB switches are equipped with LED indicators to show the status of power. This power protection design can effectively help users to better manage and operate the switch. Note that the exact amount of power consumed by the switch depends to a large extent on how much data you process. Therefore, we recommend that you choose to meet your power consumption requirements of the 10 gigabit optical switch.
Forthly, Application hierarchy
Typically, ten gigabit optical switches are suitable for two-or three-layer networks. The Exchanger is a data link layer device that recognizes the MAC address information in a packet, forwards it based on the MAC address, and records the MAC address and its corresponding port in an internal address table, data packets are sent from one port to another; a three-tier switch is a product with data exchange and routing capabilities. As a result, tier 2 switches are a cost-effective solution for small networks, while Tier 3 switches are preferred for large networks, where users can segment and manage the enterprise network without affecting bandwidth. Of course, this doesn’t mean that in any case, buying a Exchanger switch is always better than a two tier switch. Remember, only the right one is the best, and you need to make an informed choice based on your particular network environment.
Fifth, Functional requirements
When buying a switch, consider whether the functionality of the product meets your actual needs. MLAG, IPv4/IPv6, Vxlan, NVGRE, SNMP, MSTP are some of the most common features of 1000 megabit optical switches. These features are suitable for traditional or fully virtualized data centers. Some gigabit fibre switches also support advanced security features such as storm control and IGMP Snooping, which can help users monitor broadcast, multicast or unknown unicast traffic to save network bandwidth. It is recommended that you ensure that the 10,000 megabit optical switch meets your functional requirements before purchasing it.
ConclusionGigabit fibre switches are ideal solutions for home or data centre networks. It is recommended that you consider the port, capacity, power consumption, application hierarchy and functional requirements of the switch and make an informed choice before purchasing.
