  • DDR3 1600Mhz 8GB RAM
  • 500GB WD HardDisk

...


Each host has three interfaces:

  • One 10G interface for BWCTL
  • One 10G interface for latency and loss (OWAMP

...

  • )
  • One 10G or 1G interface for management

Perfsonar Host Configuration information

To support 10Gbps speeds, on paths of 100ms, 120MB of buffer must be available. Hosts configured to use jumbo frames need more buffer space as well.

...

Testing from a faster host to a slower host (e.g.,: A with 10Gbps NIC card, and B with a 1Gbps NIC card), the receive receiving host might end up dropping lots of packets. The only way to prevent that is to use the Linux 'traffic control' command, but this only works reliably up to around 5Gbps. E.G.:

...

Where xxx.xxx.xxx.xxx match de IPv4 address attached to the device p1p2

MADDASH server

This tool aims to provide both LSST and AmLight engineers a two-dimensional monitoring data as a set of grids referred to as a dashboard. Using this dashboard through the web, LSST and AmLight engineers will have a continuous and near-real-time overview of the network health, being able to anticipate actions in case of service degradation or disruption.
