Our review
Pros	Automates image provisioning, BIOS, RAID, firmware, and disk cleaning Connects bare-metal management with Kubernetes Cluster API Supports remediation, power control, boot-device management, and rolling upgrades	Supports bare-metal, diskless, and statelite OS provisioning Combines hardware discovery, firmware, power, and remote console controls Provides hierarchical management, parallel dispatch, and a RESTful API
Cons	Designed primarily for physical bare-metal management Requires a Kubernetes-centered operating model Hardware management relies on OpenStack Ironic and related interfaces	Requires a self-hosted management-node deployment Its broad hardware and cluster scope may exceed smaller environments IBM recommends Confluent as xCAT's successor
