This network card is disassembled for the server, and the adapter backplane is brand new, which is combined to form a dual-port PCI-E socket 10G network card. Please refer to CX342a for the performance of the network card. The price of this new product of the network card is more than 1,000 yuan. This is hereby explained to avoid misunderstanding.
After-sales: because of the nature of the disassembled card, the price is not high, and it can be replaced in a short period of time. We will try our best to help solve the problem as much as possible. The quality assurance service like a brand new network card may not be provided. If it takes a long time, it can be resolved through negotiation. Of course, the actual usage varies greatly, and the owner can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t solve all the problems perfectly, and can help the best. Please forgive me if you can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t help. I also hope that players can have a certain understanding of this product before purchasing.
- The adapter backplane adopts high-quality immersion gold plate and imported connectors.
- X4 and X8 have been tested, and the network card speed for large file transfer is stable at around 1100MB/S without a bottleneck. There will be small differences between different computers.
- According to the actual measurement of X1, the speed is about 3G-4G under pcie2.0, and the speed is about 5G-7G under 3.0. X1 will have a big difference between different motherboards, especially the 2.0 motherboard will have 2.5G to 4G. Please refer to the actual situation for details.
- The above is a single port test. There will be a certain difference between different motherboards in the case of dual ports at the same time, which is about 17 to 18G.
- 10 Gigabit has high requirements for software and hardware systems, and bottlenecks are prone to occur. Please have a certain understanding of the entire system.
- There is no fan by default, the fan is embedded inside, the outside is not protruding, and it will not block other cards. If you need a fan, you can place an order for the fan at the same time in the store, and it will be installed and shipped. For the time being, the fan needs to be purchased separately in the later period. It is also free to buy the fan separately.
About the bandwidth of the interface:
The network card is pcie3.0 interface, backward compatible
X1 pcie2.0 theoretical bandwidth 4G, 3.0 theoretical bandwidth 8G
X4 pcie2.0 theoretical bandwidth 16G, 3.0 theoretical bandwidth 32G
X8 pcie2.0 theoretical bandwidth 32G, 3.0 theoretical bandwidth 64G
In addition to the test environment, the network card in the actual application environment is affected by many factors such as CPU, motherboard, optical module, connection line, system setting, etc. In some cases, the maximum speed may not be reached. The coming improvement is still very straightforward.
The compatibility list is shown in the figure below. Due to different hardware and system environments, the compatibility list is for reference only.
Some in the table indicate that they have been tested, and those that are not are not necessarily unsupported, but they are not tested. Remind friends for commercial use, if you don’t understand the situation or have insufficient experience, please buy a small amount and go back to test, confirm that it can be used and then batch. For example, Internet cafes have no disks, and the system types are complicated to set up. Please confirm that you have a certain technical strength. The store cannot provide technical support in this regard. It is recommended to consult the diskless system developer to confirm whether this model is supported.
