Zero Touch Provisioning - Network Automation for Cloud Data Centers


  • As simple as rack, connect and power-on
  • Standards based, no need to implement proprietary platforms
  • Advanced scripting capabilities
  • Maintain compliance and network integrity
  • Fully automate network and server provisioning
  • ZTP Applications

Using standards based protocols (e.g. DHCP, T/FTP, HTTP) the network can be rapidly provisioned. Advanced scripting capabilities allow the administrator to tailor boot configurations based on a variety of parameters, meeting the needs of even the most complex data center deployments. Combined with other Arista features, like VMTracer's adaptive VLAN configuration, data center managers can fully automate the bring-up of network elements and virtual servers. Leverage Arista's unique 'hands-off' provisioning to enable the Cloud Data Center.

Zero Touch Provisioning Overview




Applications

  • Fully automated deployment of a Virtualized Data Center: Arista switches deployed with ZTP, are downloaded with VMTracer configuration parameters.  As VMware vSphere servers boot and instantiate virtual machines, VMTracer automatically configures the VLANS for the VMs.  No manual configurations are necessary and the data center has autobooted and is ready for use.
  • Using templates with Puppet/Cobbler to configure switches in an HPC cluster: Extending the model of cluster server provisioning, the HPC manager uses templates to quickly deploy additional racks of servers in the HPC cluster.  Along with the server templates, the manager adds a template for the Top of Rack (ToR) switches as well.  Now as racks of servers are added to the cluster, both network and server platforms are configured and integrated into the existing cluster.
  • Using scripting to install Linux extensions to EOS: A service provider writes a shell script that is downloaded to a switch with ZTP at boot time.  The shell script downloads an OpenVPN RPM, installs and configures it. Its last function is to send a message to the NOC with its logs and configuration information.  After the switch reboots, managers can securely access the switch from the remote NOC for provisioning.
