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. Starting in Release 6.3.0, CSO supports syslog streaming services, which enable users to access the device syslog notifications. You can opt for streaming services by enabling the streaming option during the install or upgrade procedure. The syslogs are streamed in real-time and can be retrieved through REST API calls.

| Memory per Server | 256 GB RAM | 320 GB RAM |
| Disk Size per Server | 5 TB | 8 TB |
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.
