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

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 SD-WAN solution. You must use these specific versions of the software when you implement the SD-WAN solutions.

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, except Contrail Analytics VMs, on CSO servers

Ubuntu 16.04.5 LTS

Operating system for Contrail Analytics VMs on CSO servers

CentOS version 7.7.1908

Hypervisor on CSO 6.0.0 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
