Legacy data center networks were designed for bare metal servers that consolidated all application resources within a single server. Therefore, east-west bottlenecks were rarely an issue. But now, the bandwidth between compute, storage and the network is a major concern. One way to address this bottleneck is to move from a traditional three-tier network design to a leaf-spine architecture in the data center. This technique creates a full mesh of network connectivity between the data center access layer (leaf nodes) and the aggregation layer (spine nodes). Since all nodes are connected, every resource within the data center is the same number of hops away. Additionally, each uplink between the leaf and spine nodes can be utilized to its fullest extent. As new technologies – especially those hosted in the cloud – expand and stretch the capabilities of production networks, they often creates bottlenecks on the Internet edge, in the WAN, along switch uplinks and within the data center. Fortunately, the number of tools network engineers have to alleviate bottlenecks is growing as well.
