Cluster Expansion is another significant value add which helps prepare the cluster nodes before adding them to the HCI cluster. OMIMSWAC readies the cluster nodes before adding them, but expanding a cluster requires some steps recommended by Microsoft. For details about creating and expanding clusters, see HCI Operations Guide—Managing and Monitoring the Solution Infrastructure Life Cycle. The new node to be added is checked for high-level compatibility, licensing, and HCI Configuration Profile to ensure it can be added successfully and consistently. Following these checks, a compliance check will be performed to ensure the new nodes’ BIOS, firmware, and driver versions are consistent with those running on the cluster. If in case the new node is non-compliant the workflow will guide through an update process where the node is updated followed by a reboot.
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.
The AX nodes are protected from unintended changes that occur in a data center for various reasons by Infrastructure lock built into the tool. With this lock turned ON, the feature prevents the infrastructure from any configuration changes or updates to be done to the BIOS, iDRAC, firmware, and drivers. The tool facilitates these setting changes across all the nodes in the cluster. It also allows administrators to disable the infrastructure lock for HCI and failover clusters for the intended configuration changes, and update the cluster, and enable it back automatically after the operation is finished.
This feature allows you to enable Secured-Core server for the infrastructure (failover clusters) running on Azure Stack HCI and Windows Server 2022.
The Dell OpenManage Integration extension’s home page is carefully designed to give an overall health status of the cluster in a single view. Its monitoring, inventory, and troubleshooting capabilities include:
