Using the CC-NIE funding, OIT has deployed 10 physical servers as perfSONAR (PS) around the campus. These servers are generally deployed in pairs – one of which handles bandwidth measurements and one of which handles latency measurements. In order to validate local switch performance, there has been some “mixing” of bandwidth and latency measurements in the infrastructure.
We plan to re-do our configuration using the latest PS build which should allow us to combine bandwidth and latency measurements on the same server using different NICs.
The current servers are:
| Server | Location | VRF | Primary Role | Notes |
| tel-perfsonar-01.netcom.duke.edu | 0200 Telcom Bldg | No VRF (Outside) |
Latency | CC-NIE Server |
| tel-perfsonar-02.netcom.duke.edu | 0200 Telcom Bldg | No VRF (Outside) |
Bandwidth | CC-NIE Server |
| fitz-perfsonar-01.oit.duke.edu | Fitz East DC | DataCenter | General Purpose | OIT Networking |
| fitz-perfsonar-02.oit.duke.edu | Fitz East DC | DataCenter | Latency | CC-NIE Server |
| fitz-perfsonar-03.oit.duke.edu | Fitz East DC | DataCenter | Bandwidth | CC-NIE Server |
| bio-perfsonar-01.biology.duke.edu | BioSci DC | Biology | Latency | CC-NIE Server |
| bio-perfsonar-02.biology.duke.edu | BioSci DC | Biology | Bandwidth | CC-NIE Server |
| phy-perfsonar-01.phy.duke.edu | Physics DC | Physics | Latency | CC-NIE Server |
| phy-perfsonar-02.phy.duke.edu | Physics DC | Physics | Bandwidth | CC-NIE Server |
| bio-perfsonar-03.phy.duke.edu | BioSci DC | Physics | Latency | CC-NIE Server |
| bio-perfsonar-04.phy.duke.edu | BioSci DC | Physics | Bandwidth | CC-NIE Server |
| singapore-perfsonar-01.oit.duke.edu | Singapore DC | Public | Bandwidth | VM |
| singapore-perfsonar-02.oit.duke.edu | Singapore DC | Private | Bandwidth | VM |
The servers listed above give us the ability to test:
Traffic between servers in different buildings on the same VRF
Traffic between servers in the same building on different VRFs
Traffic in and out of the primary data center (Fitz East)
Traffic in and out of the edge of the network (Telcom Servers)
Traffic in and out of server in the Singapore DC
