Attending SC15? Get a Close-up Look at Virtualized Science DMZs as a Service

ESnet, NERSC and RENCI are pooling their expertise to demonstrate “Virtualized Science SMZs as a Service”  at the SC15 conference being held Nov. 15-20 in Austin. They will be giving the demos at 2:30-3:30 p.m. Tuesday and Wednesday and 1:30-2:30 p.m. Thursday in the RENCI booth #181.

Here’s the background: Many campuses are installing ScienceDMZs to support efficient large-scale scientific data transfers. There’s a need to create custom configurations of ScienceDMZs for different groups on campus. Network function virtualization (NFV) combined with compute and storage virtualization enables a multi-tenant approach to deploying virtual ScienceDMZs. It makes it possible for campus IT or NREN organizations to quickly deploy well-tuned ScienceDMZ instances targeted at a particular collaboration or project. This demo shows a prototype implementation of ScienceDMZ-as-a-Service using ExoGENI racks (ExoGENI is part of NSF GENI federation of testbeds) deployed at StarLight facility in Chicago and at NERSC.

The virtual ScienceDMZs deployed on-demand in these racks use the SPOT software suite developed at Lawrence Berkeley National Laboratory to connect to a data source at Argonne National Lab and a compute cluster at NERSC to provide seamless end-to-end high-speed data transfers of data acquired from Argonne’s Advanced Photon Source (APS) to be processed at NERSC. The ExoGENI racks dynamically instantiate necessary compute virtual resources for ScienceDMZ functions and connect to each other on-demand using ESnet’s OSCARS and Internet2’s AL2S system.
