This section provides an overview of the management infrastructure and the software components that run on VMs within the management cluster of this Ready Stack solution.
The management infrastructure consists of three PowerEdge R640 servers that form a cluster. Management components are virtualized to provide high availability. Redundant 10/25 Gb Ethernet uplinks to the network infrastructure and redundant 16Gbps FC uplinks to the storage array that is combined with failover clustering ensure that management components stay online. Dual Networking S4148T switches provide OOB connectivity. iDRAC ports in each management and compute cluster connect to this switch.
Agentless OOB monitoring and agent-based monitoring with OpenManage Server Administrator (OMSA) are available for 14th generation PowerEdge servers.
The management software components include:
The following figure depicts the management infrastructure.
Figure 13. Management Infrastructure
The management software components for Ready Stack require a nominal amount of virtual server resources. Although the components can reside on the compute server cluster alongside the compute workload, Dell EMC recommends that you run them on a dedicated management server cluster to achieve less resource contention.
The following table describes the optional management cluster, which consists of a minimum of two PowerEdge R640 servers (three are recommended). To use external storage, which is preferred, connect the management cluster hosts to Unity shared storage.

OMIMSSC provides agentless, operating system- and hypervisor-agnostic configuration and deployment as well as uniform BIOS, driver, and firmware updates for 14th generation PowerEdge servers. Automated processes reduce the steps, time, and costs that are required to configure the PowerEdge servers from a bare-metal state. The preparation of remote one-to-many operating system deployments within multivendor operating system and hypervisor environments is also automated.
The management software components run on VMs that reside in the management cluster. The following table shows the management components in the bundle and the recommended VM sizing of those components:
