CPU core management feature right sizes the cluster for workloads which creates the best Return on Investment (ROI). The Azure Stack HCI operating system is billed based on subscription which is on a per core basis for on-premises servers. This can become expensive because many servers are equipped with high core count processors. OMIMSWAC can help lowering this expense and optimizing the Total Cost of Ownership (TCO) by modifying the CPU core count dynamically. The tool provides a summary of current CPU core configuration along with available cores for expansion or reduction. Users can adjust and simultaneously apply the CPU core count BIOS settings without leaving the OpenManage Integration extension with a reboot-now or on a next-reboot option. Because this happens through Cluster-Aware Updating, the mandatory reboot of servers will not interrupt the running workloads.
