Based on the CPU core manufacturer (Intel or AMD) you can configure the cores as follows. To maintain cluster
homogeneity, OMIMSWAC will apply the same configuration across all nodes.
NOTE: Changing the number of cores impact the overall core count of the cluster. Ensure that you are using the right
number of cores to maintain the balance between power and performance.
CPU Type Instructions
Intel CPU
● Select number of cores you want to enable per CPU.
● Minimum number of cores that can be enabled is four. You can enable all the cores that you want to
manage workloads.
AMD CPU
● Using the first slider, select the number of CCDs per processor you want to enable.
● Using the second slider, select the number of cores per CCD you want to enable.
● You can enable any numbers of cores at a minimum. You can also enable all the cores that you want to
manage workloads.
6. Select one of the following options to apply the changes and reboot nodes.
● For an individual node:
○ Apply and Reboot Now: Select the option if you want to apply the changes and reboot the node now. Ensure to
take care of the workloads before applying the changes.
○ Apply at Next Reboot: Select this option if you want to apply the changes now and reboot the node later. Ensure
that you reboot the node later to successfully apply the CPU core changes. Also, ensure to take care of the workload
before rebooting the node.
● For a cluster:
○ Apply and Reboot Now: Select the option if you want to apply the changes and reboot the cluster nodes now. Dell
EMC recommends using this option as the nodes are rebooted automatically by taking care of the workloads.
Before clicking "Apply and Reboot Now", ensure the followings:
￭ As OMIMSWAC uses the Microsoft Cluster-Aware Updating feature framework to perform cluster updates,
ensure the Failover Clustering feature and Failover Clustering Tools are installed on all the cluster nodes
before rebooting the cluster. For more information, see Cluster-Aware Updating requirements and best practices
in Microsoft document.
￭ Dell EMC recommends to test the cluster readiness before rebooting the cluster. For more information, see Tests
for cluster updating readiness in Microsoft document.
○ Apply at Next Reboot: Select this option if you want to apply the changes now and reboot the cluster nodes later.
Ensure that you reboot the cluster nodes later to successfully apply the CPU core changes. Also, ensure to take care
of the workload before rebooting the nodes.
NOTE:
Apply and Reboot now process requires the CredSSP to be enabled. To improve security, disable CredSSP after
the CPU configuration changes is complete.
7. To apply the changes, click Confirm.
Under Compute Resources the status of the changes is displayed. Click View Details to see the progress at a node level.
