devices. Fabric infrastructure can be seen as the foundation of SAN. When a device sends a frame of data to the switch, the switch routes the frame to the target device. In fact, a frame can be forwarded before it is fully received. Fiber Channel switches are also intelligent. They can provide various Fabric services, including services for locating other nodes on the Network (simple name service). They can automatically establish routes with other switches in Fabric, you can also partition dev

-play" process. Multiple ports Currently, many vswitches provide Ethernet ports at 10/100 Mbps. However, in the face of rapid technological development, it is recommended that you consider providing a Mbps port and a GBIC port switch to ensure future Gigabit access and optical fiber access needs. Pay attention to whether the stack link can achieve full duplex, stacking unit and uplink redundancy, and whether there is a single fault point. The star sta

Gigabit upwards and bind links to increase bandwidth, load Balancing and link redundancy are achieved. gigabit connections to eight-layer switches are implemented downward to avoid network transmission bottlenecks. According to statistics, more than 80% of the data traffic in the network is formed by the Internet and access servers. Therefore, the performance of devices at the aggregation layer is particularly important. If a department has a large number of users or frequently accesses a dedic

shortest path (directly transmitted on the full-duplex 40 Gbps connection between the second and third switches ). This not only improves the usage efficiency of stack bandwidth, but also reduces the latency of data transmission. FAST technology also inherits the advantages of "secure stack. It enables smooth network upgrade without affecting user services in case of a fault. When adding a new switch to the stack, you only need to perform a simple connection. FAST technology makes it a "plug-a
