Dell Technologies recommends the following server configurations for use with Predictive Maintenance for IT Operations.
PowerEdge servers are built to support the work of IT organizations. They are engineered to handle the most demanding business applications and are designed with specific features to better run workloads, including:
As the foundation for a complete and adaptive solution, PowerEdge servers deliver exceptional performance and management advantages, powering the business applications that customers run most often. PowerEdge servers combine with the innovative OpenManage Essentials ( OME) systems management portfolio and industry-leading workload solutions to provide intelligent yet simple technology. This combination gives you the power to do more in the most complex environments.
The latest generation of servers responds to customer needs in the following areas:
This validated design uses the PowerEdge R650, PowerEdge R750, and PowerEdge R750xa servers.
Infrastructure nodes are used to host Robin Cloud Native Platform, the Kubernetes control plane, and HAProxy and keepalived for load balancing. Predictive Maintenance for IT Operations requires three infrastructure nodes.
