Operator Nexus ensures the availability of three active control plane nodes in instances with three or more compute racks. For configurations exceeding two compute racks, an extra spare node is also maintained. These nodes are strategically distributed across different racks to guarantee control plane resiliency, when possible.

During runtime upgrades, Operator Nexus implements a sequential upgrade of the control plane nodes, thereby preserving resiliency throughout the upgrade process.

Operator Nexus maintains an active control plane node and, if available, a spare control plane instance. For instance, a two-rack configuration has one active Kubernetes Control Plane (KCP) node and one spare node.

In disaster situations when the control plane loses quorum, there are impacts to the Kubernetes API across the instance. This scenario can impact a workload's ability to read and write Customer Resources (CRs) and talk across racks.
