The San Diego Supercomputer Center (SDSC) was founded in 1985 to advance science and engineering through computational science and data-intensive, High-Performance Computing (HPC), and that leadership continues today. Their challenges are they need to provide cost-effective and scalable data center colocation to support data-intensive research for the University of California system. They chose Juniper Networks to overcome these challenges. They implemented EX series Ethernet switches, MX series 3D universal edge routers, SRX series services gateways. The results of implementing the Juniper Networks were support data-intensive, advanced research projects, it provide cost-effective, scalable, multi-gigabit network services for data center and it support the supercomputing needs of multiple departments in the UC system.
