The Huawei S5700-EI switches can be applied in large enterprise networks and data centers, functioning as an access device or aggregation device to improve network reliability through features like link aggregation and dual-homing. In data centers, the S5700-EI connects servers and aggregates their traffic to uplink devices via trunk links, and multiple switches can be stacked to facilitate maintenance and increase reliability when many servers are present. Sample deployments of the S5700-EI are described for large enterprises and data centers.
