EDDnet Provisioning Discussion

  • Partner peering contributions - How to best provision REDDnet hardware; basic upshot of discussion was that we would deploy more notes, not fully provisioned with storage.
  • Deploy a few partially populated racks to core institutions (To begin Summer 2007)
  • Varying size deployments to highly interested users
  • What kind of agreement is needed with partnered sites? One thing agreed on was that there would be no requirement that the partners "contribute" their own storage to REDDnet.
  • Management of time based allocations
