This section provides an overview of the Ready Stack management infrastructure and the software components that run on VMs within the management cluster.
The management infrastructure typically consists of at least two PowerEdge R440 or R640 servers that form a management cluster. Dell Technologies recommends using three PowerEdge servers for HA clustering. Management components are virtualized to provide high availability. Redundant 10/25 GbE uplinks to the network infrastructure and redundant 16 Gb/s FC uplinks to the storage array combined with vSphere High Availability (HA) ensure that management components stay online. If HA is required, two Dell EMC PowerSwitch S4148T switches provide OOB connectivity. iDRAC ports in each management and compute cluster connect to those switches.
For example, for a VMware environment, the management software components can include:
