The substation automation and SCADA systems should have very low latencies to address real-time monitoring and control of electrical substation assets and operations. Depending on the size of the substation, determined by factors such as number of bays, intelligent electronic devices (IEDs), and tags, the virtual machines in the solution should be assigned an appropriate set of compute, storage, and network resources to meet the latency and throughput requirements. Consider leveraging more CPU cores, higher memory, and high-performance storage for large deployments, as compared to medium or low deployments. See the Sizing and Scaling Guidance chapter for further information.
Industrial gateways have limited resources compared to VMs deployed on PowerEdge servers. Also, they may not have access to persistent resources locally. Hence, gateways can be leveraged to run low compute applications such as the ABB ZEE600 Runtime (HMI) clients.
