  1. Supporting experiment workflows on ExoGENI with OMF and GIMI Ilia Baldine, Jeff Chase, Mike Zink, Max Ott

  2. Testbed • 14 GPO-funded racks • Partnership between RENCI, Duke and IBM • IBM x3650 M3/M4 servers • 1x146GB 10K SAS hard drive +1x500GB secondary drive • 48G RAM • Dual-socket 8-core CPU w/ Sandy Bridge • 10G dual-port Chelseo adapter • BNT 8264 10G/40G OpenFlow switch • DS3512 6TB sliverable storage • iSCSI interface for head node image storage as well as experimenter slivering • Each rack is a small networked cloud • OpenStack-based • EC2 nomenclature for node sizes (m1.small, m1.large etc) • Interconnected by combination of dynamic and static L2 circuits through regionals and national backbones • http://wiki.exogeni.net

  3. ExoGENI Status • 3 racks deployed • RENCI, GPO and NICTA • 2 existing racks • Duke and UNC • 2 more racks coming • FIU and UH • Connected via BEN (http://ben.renci.org), LEARN and NLR FrameNet, I2

  4. ExoGENI slice isolation • Strong isolation is the goal • Compute instances are KVM based and get a dedicated number of cores • VLANs are the basis of connectivity • VLANs can be best effort or bandwidth-provisioned (within and between racks)

  5. Experiment Workflow
