FY18 Capability: Establishing Data Transfer between Sites
The Data Backbone file provisioning was procured in 2017. Data transfer services on top of the file services are needed, supporting production and development use cases.

The use cases include

  • File transfers by the workload management system for batch production.
  • Production ingest of Spectrograph and engineering data from LSST camera test stands.
  • Data service of retained data to remote authorized users.
  • Bandwidth demonstrations to support our satellite computing center at CC-IN2P3.

This capability will consist of DTN nodes that are in the LSST VM farm. These nodes will be part of the VSphere environment at NCSA in NPCF dedicated to the LSST environment. There will be production and test nodes allowing for development work of the tools while production work can continue.

Tentatively planning for Jan-Feb. deployment.
