The first CRG in PowerOne, the vSphere Management Cluster, consumes a minimum of, four compute sleds in the first compute domain. The vSphere Management Cluster runs management VMs that control the hypervisors (ESXi hosts) on both vSphere Management Cluster and other clusters.
Management virtual machines can include both—those deployed by the platform (such as vCenter) and those that are deployed by the operator.
Provision management, monitoring, and infrastructure services on the vSphere Management Cluster, which is configured as a VMware vSphere cluster that provides high availability to these critical services.
The vSphere Management Cluster has a minimum of two VMware vCenters: a management vCenter and a compute vCenter. The management vCenter controls the virtual environment of the vSphere Management Cluster. The compute vCenters manages the virtualization of one or more CRGs.
The vSphere Management Cluster also contains VMware NSX-v components, which can be optionally configured to manage NSX-T deployments for customer workloads (CRGs). In PowerOne, the PowerOne System Fabric provides network connectivity from the customer environment to the vSphere Management Cluster.
VMware vRealize Operations (vROps) is optional for use in PowerOne. If it is purchased as part of PowerOne, vROps management packs are included. The Dell EMC PowerOne management packs are developed for vROps. They monitor the health, capacity, and performance of system resources in PowerOne, and help to rapidly identify and troubleshoot system issues.
PowerOne allows bare-metal resource allocation. They are independent resources that are not managed or controlled by PowerOne.
Compute sleds can be made available for bare-metal allocation by setting them to manual mode. Storage must be provisioned through port groups reserved for bare metal.
