1、 Analysis of new 10 Gigabit sailing opportunities:
Server data transmission bottleneck. With the development of server hardware, the disk that restricts the performance of the server has also been greatly improved. Nainor introduced the IOPs of Intel dc.p3500 nvme SSD (the number of read and write I / OS per second on the disk) and the best combination of read and write speed and memory cache. At present, the data transmission bottleneck of the server is actually transferred from the disk to the transmission between the server network card and the core switch. The traditional Gigabit can no longer meet the growing demand With the emergence of dianjingguan VR Internet cafe, it can effectively stimulate consumption, but now another important trend of Internet cafe is 10 Gigabit bandwidth. We know that at present, the capacity of computer games is very large, often dozens of GB of downloads. It is difficult to support the huge downloads of a large Internet cafe only by the previous gigabit optical fiber.
2、 Internet bar 10 Gigabit enters the second generation upgrade period
In the current star network structure, the backbone is already 20g, and even 10 Gigabit to the desktop is slowly rising. The follow-up of nvme technology of server disk has also broken through the disk bottleneck, so it is urgent to upgrade the server to the backbone core switch
After the large-scale deployment and application of 10G SFP +, 40g qsfp + is considered to be the most advantageous scheme in the next generation 40g network deployment
3、 Internet bar 10 Gigabit to desktop to achieve a more perfect 10 Gigabit solution
Compared with 10g SFP + switch, the bandwidth of st-w9484qm of 40g qsfp + switch is increased by 4 times. It has obvious advantages in power consumption, volume and cost. Users can fully enjoy various application convenience brought by 40g qsfp +, and then cooperate with st-w9142rm 10 Gigabit to realize a more perfect 10 Gigabit solution on the desktop. Only a good solution can bring better experience to customers, Only good experience can continue value. Therefore, 40g qsfp + switch st-w9484qm will become the preferred product for users in the Internet cafe industry.
Product features
◆ high performance full line fast forwarding
This series of switches has the full line speed 10 Gigabit switching and forwarding capacity, with the maximum switching capacity of 1280gbps and the maximum packet forwarding rate of 952.32mpps. It can be applied to a variety of network environments and is an ideal choice for establishing an intelligent 10 Gigabit backbone network.
◆ flexible port aggregation function
The port aggregation function is used for cascading between switches. Through the port aggregation group, it provides bundled high bandwidth for data exchange between switches, improves network speed, breaks through network bottlenecks, and greatly improves network performance.
◆ network monitoring image to improve network security
The port mirroring function can copy the traffic of one port to another specified port. This mechanism can help network managers track network errors and abnormal data packets without interrupting the network, which is convenient for monitoring the traffic security of the whole network. At present, it is widely used in the public security monitoring system in the Internet cafe industry.
◆ efficient heat dissipation design
In order to better cooperate with the air duct design of the data center, it provides users with an efficient direct cooling air duct scheme of forward air and rear air, which greatly improves the heat dissipation effect of the switch. At the same time, the cooling fan equipped with the equipment has intelligent speed regulation function to reduce the power consumption of the whole machine under the condition of meeting the cooling requirements.
◆ rich IPv4 and IPv6 Routing features
The device supports not only IPv4 static routing, rich IPv4 routing features such as ripv1 / V2, ospfv2 and bgpv4, but also IPv6 static routing, rich IPv6 Routing features such as RIPng and OSPFv3. In addition, the interaction of neighbor nodes can be managed through IPv6 Neighbor Discovery Protocol (NDP).
◆ excellent management
Support rich management interfaces, including console and out of band management interfaces. Web network management and telnet configuration make device management more convenient. It also supports encryption methods such as ssh2.0, making the management more secure.
This scheme cooperates with 10 Gigabit to desktop to realize a more perfect 10 Gigabit scheme. Therefore, the demand for 40g network scheme has become a trend in the next few years. However, how to build a real high-speed, safe and cost-effective 40g network scheme is a problem to be considered by agents who want to eat crabs first. According to this demand, this scheme introduces the current 40g network scheme and the most advanced solution in the industry, hoping to bring some enlightenment to the employed technology siege lions.
Managed switches:
This scheme recommends the layout of high-end E-sports Internet cafes. Nainor w9484qm 10 Gigabit quasi three-layer core switch, and the network wiring adopts the star network 10 Gigabit scheme. 48 10 Gigabit SFP + interfaces, which can adapt to Gigabit, connect the gigabit optical power conversion module to access the Gigabit equipment of the Internet cafe, and 4 qsfp + 10 Gigabit 40g high-speed network interfaces. By connecting with the server 10 Gigabit 40g, the main single 40g is realized, breaking the current 10 Gigabit network bottleneck of the Internet cafe, and actively responding to the requirements of large data traffic throughput of the Internet cafe network. The backplane bandwidth of the switch is up to 1280g and the forwarding rate is 952.32mpps/s, so as to easily deal with the data forwarding of large traffic such as diskless systems, games and movies.
Access layer switch:
The scheme adopts nainor w9142rm 10 Gigabit to desktop switch, 2 SFP + 10 Gigabit interfaces and 14 10g adaptive interfaces. Support 10 Gigabit port aggregation. The backplane bandwidth of up to 320G can effectively ensure that the network data from the PC end of the Internet cafe to the server end can interact without delay and make a one-time investment. At the same time, it can ensure that the Internet Cafe will not be eliminated by the market within 5 years.
