System Requirements

OS / Package Requirements

• RedHat/CentOS7
• EPEL Repository (https://fedoraproject.org/wiki/EPEL)
• GRNOC OpenSource Repository (coming soon)

Hardware Requirements

Base

• 1 CPU for general system and an additional 0.5 CPU for each switch to be connected to VCE
• 1G of memory for general system / cache and 200MB of memory for each switch connected to VCE
• Disk usage (excluding base OS) 5G of space for the installation / configuration, depending on how long you want to keep the logs, each switch process will create approximately 2MB/day for logs

Statistics

• Grafana (minimum 256MB ram, 1 cpu)
• Redis (minimum 512MB ram, 1 cpu)
• SIMP (minimum 512MB ram, 1 cpu) for every 10 nodes @ 5m poll interval
• TSDS (minimum 1GB ram, 2 cpu) for every 450 interfaces @ 5m poll interval

Other Considerations

Additional tools / authentication may require additional resources, please review any additional tools / applications you will install on the VCE server to verify they will fit in these system requirements.

Example

For a 3 switch VCE instance and 2 days of logs:

• 3 CPUs
• 1.6G of memory
• additional 6G of disk space for the installation and logs

Network Access / Firewall

Inbound:

• HTTP (80)
• HTTPS (443)

Outbound (to switches):

• SSH (22)
• NETCONF (830)
