A high-performance network fabric connects the cluster nodes in a Cluster Data network. An additional Edge network provides an interface between the cluster and external systems and applications. There is also a Management network that connects the iDRAC management ports of the PowerEdge servers for hardware provisioning and management.
The network is designed to meet the needs of a high performance and scalable cluster, while providing redundancy and access to management capabilities. The architecture is a leaf and spine model that is based on 25 GbE networking technologies. It uses PowerSwitch S5248F-ON switches for the leaves and PowerSwitch Z9432F-ON switches for the spine.
