Astronomy, like High Energy Physics, will bring GB/sec instruments on line within the next decade. As the example of the LHC shows, both technical and political forces imply a multi-tiered architecture in which all data is replicated for reliabilty and performance at several Tier-1 centers and extracts will be stored at many Tier-2 sites. This suggests a world-wide federation of about 10 peta-scale sites, each associated with an LSST-class instrument, interconnected with high-speed networking, forming the core of the Virtual Observatory. Unlike HEP, there is great interest in cross-correlating astronomy data from multiple instruments and telescopes. Users need easy access to data from all sites and some will want to build their own Tier-2 archives. The real-time nature of LSST (and probably other instruments) forces substantial archive and processing facilities co-located with the telescopes.
