The following factors need to be considered:
1. Bus interface type of gigabit optical fiber network card
At present, the bus interface types of gigabit optical fiber network card are PCI, PCI-X and pci-e. PCI-E is the new third generation input / output (I / O) standard. Compared with PCI and PCI-X, PCI-E can improve the performance of Ethernet network and provide strong advantages for Ethernet connection between server and switch.
2. Interface type of gigabit optical network card
Because the gigabit optical network card needs to be connected with the network, it must have an interface to connect with the computer network equipment. At present, the common interface types of gigabit optical fiber network card are RJ-45 interface and SFP optical fiber interface. Different interfaces are suitable for different network types. The gigabit optical fiber network card with different interfaces can be selected according to the network type, such as the gigabit optical fiber network card with SFP optical fiber interface.
3. Ports of gigabit optical network card
The ports of the gigabit optical network card are mainly used for accessing the Internet, storage and management. At present, the port number of the gigabit optical network card on the market includes 1 / 2 / 4 / 6 port number, among which the two port Gigabit optical network card is the most common. When selecting, the gigabit optical network card corresponding to the port number can be selected according to the actual demand.
4. Cost performance (performance and price) of gigabit optical network card
A high cost-effective gigabit optical network card can effectively save costs under the premise of efficient Ethernet connection.
The use of optical network card will tend to be higher speed, such as 10G Optical network card, 25g optical network card, 40g optical network card, 100g optical network card, etc.
