A typical data center scenario

The access layer utilizes SR3300/SR3600/SR3700 switches to deliver high-density 10GE/25GE server access solutions, while the aggregation layer employs SR3800 switches for 100GE high-bandwidth aggregation. By integrating technologies like stacking and link aggregation, the system establishes a high-performance, highly reliable, and redundant data center network.

Cloud data center scenario

The SR3300/SR3600/SR3700 serve as Leaf nodes in cloud data centers, while the SR3800 functions as Spine nodes. These devices are interconnected via 100GE ports to create a fully connected 100GE end-to-end solution. By leveraging technologies such as stacking, link aggregation, VxLAN, and EVPN, the system establishes a non-blocking Layer 2 VxLAN Overlay network, enabling large-scale virtual machine migration and flexible deployment of user services.
