Hardware and Software Requirements for Contrail Service Orchestration

 

Contrail Service Orchestration (CSO) requires commercial off-the-shelf (COTS) servers, specific network devices, and specific software versions. The following sections list the hardware and software that are required and have been tested for the cloud customer premises equipment (CPE) and software-defined wide area network (SD-WAN) solutions.

Server Requirements for Contrail Service Orchestration

You must use COTS servers for the following functions:

  • Contrail Service Orchestration (CSO) servers

  • Contrail Analytics servers

Note

CSO Release 5.1.0 supports only KVM hypervisors. CSO Release 5.1.1 and later support KVM and ESXi 6.7 hypervisors.

Table 1 lists the server requirements.

For ESXi hypervisors, each virtual machine (VM) must be created with a single partition.

For KVM hypervisors, OS and Data partitions are automated.

Table 2 lists the software that has been tested for the COTS servers used in the hybrid WAN solution. You must use these specific versions of the software when you implement the Hybrid WAN and SD-WAN solutions.

Table 2: Software Tested for COTS Servers

Description

Version

Operating system for all COTS servers

Ubuntu 16.04.5 LTS

Note: You must perform a fresh install of Ubuntu 16.04.5 LTS on the CSO servers in your deployment because upgrading from a previous version to Ubuntu 16.04.5 LTS might cause issues with the installation.

Operating system for VMs on CSO servers

Ubuntu 16.04.5 LTS

  • You must install Ubuntu 16.04.5 LTS on the VMs that you configure manually. .

  • The provisioning tool installs Ubuntu 16.04.5 LTS on all the VMs that it configures.

Hypervisor on CSO 5.1.2 servers

KVM hypervisor provided by the Ubuntu operating system on the server or VMware ESXi Version 6.7.

Note: A mix of different hypervisors across machines is not supported.

Additional software for CSO servers

Secure File Transfer Protocol (SFTP)

Contrail Analytics

Contrail Release 4.1.4.0-65
