Metacloud has a control plane designed to have controller nodes that are highly available. The Dashboard, API endpoints, and user-facing elements are protected from down-time through a highly available architecture for each Availability Zone (AZ). Your Availability Zone name was determined when you ordered the product. The hypervisor nodes and networking gear are named based on the Availability Zone name.
Your cloud was ordered in one of three sizes for compute and networking capacity, per Availability Zone:
- Starter—Contains up to 40 compute servers and 2.5 Gbps throughput for networking.
- General Purpose—Provides up to 100 compute servers and 10 Gbps networking throughput.
- High Performance—Scales up to 400 compute servers with 20 Gbps throughput.

Your configuration can be modified to suit your storage considerations.
- Ephemeral—All storage is co-located on the compute servers and instances do not have access to volume storage.
- Persistent—Storage arrays enable users to programmatically provision volumes for instances to use. In addition, your cloud was configured to use a particular storage driver; NFS or Ceph.
To determine your cloud’s storage configuration, log in to the Dashboard as an Administrator and select Admin and then select Storage. Ephemeral storage is indicated by Local Disk and Persistent storage displays a storage driver in the Dashboard, such as NFS or Ceph.
In addition to the compute capacity sizing and networking throughput, three networking models are available:
- Cisco Managed Network (default, recommended option)—The Metacloud Support team manages and monitors the network platform. Neutron Networking features are available through the Dashboard and API endpoints.
- Cisco Managed Gateway Networking—In the Cisco Managed Gateway networking option, Cisco manages the network equipment that provides the network gateway between the Availability Zone and the customer-provided external gateway or router. All physical network switches used in the Availability Zone are provided, configured, and managed by your networking team. In this scenario, the Cisco team manages all the Layer 3-related components, while Layer 2 is managed by your team.
- Customer Managed Networking—You manage all networking equipment within and beyond the Availability Zone. With this model, Neutron Networking API provisioning, such as create routers are not available. Routing between VMs and VM access to any external networks are completely managed by the customer.
