Hardware Specification and Architecture
This section contains the specification of the used Ampere hardware and software resources for the reference OpenNebula deployment.
Architecture
The target high-level cloud architecture overview is shown below. Two Ampere servers are used: the first for hosting the OpenNebula Front-end services and VMs, the second for hosting VMs only. A simple VXLAN networking is configured for the communication between the VMs, so all deployed VMs are attached to the same logical LAN.
Hardware Specification
The tables below detail the characteristics for the Front-end, virtualization host, storage, networking and provisioning model.
