The document discusses creating a California-wide cyberinfrastructure for data-intensive research. It outlines efforts to connect all UC campuses and other research institutions across California with high-speed optical networks. This would create a "big data plane" to share large datasets. Several campuses have received NSF grants to upgrade their networks and implement Science DMZ architectures with 10-100Gbps connections to CENIC. Connecting these resources would provide researchers access to high-performance computing, large scientific instruments, and datasets. This would support collaborative big data science across disciplines like physics, climate modeling, genomics and microscopy.
