22 Installer Differentiators Bare-Metal Deployment Utilizes latest modern toolsets: Python, Ansible Innovative use of UCS CIMC APIs to configure HW Deploys RedHat Enterprise Linux (RHEL) and RHEL OpenStack Platform (OSP) Containerized Deployment of OpenStack Services Verifiable HA Deployment

23 Cloud Pulse OpenStack Health Check Health Checks using CloudPulse tool. Why are cloud health checks so important? Important to NFV applications, Telcos have strict SLAs. VNFs can be moved to a different cloud if OpenStack failure is detected early. Operators need to be aware of the failure before the customer experiences failure. Characteristics of a healthy OpenStack cloud: Control Plane: Openstack services can handle APIs and reply with an appropriate status. Openstack resources can be created and deleted. Data Plane: VMs can communicate within and/or across networks.
