As part of an ongoing effort to keep UCInet up to date and able to meet the research and instructional needs of the campus, NACS is pleased to announce the completion of the network backbone upgrade.
The upgrade consisted of replacing and configuring the routers in the four core sites as well as upgrading UCI’s border router. Collectively UCI now enjoys a 10 gigabit (10 billion bits per second) redundantly connected backbone core, including two 10-gigabit connections to the border router and two to the Calit2 building.
Some schools such as Engineering, ICS, Physical Sciences, Biological Sciences, and parts of the College of Medicine, already have Gigabit Ethernet (1 billion bits per second) connections to the backbone and will see an immediate speed boost in some applications.
The next network upgrade project will focus on the “distribution layer” which will allow many of the remaining buildings at UCI to take advantage of the high-performance network backbone. In addition to the increase in network transfer speeds, NACS looks forward to helping the campus use this new architecture for future network protocols and applications.
After the current distribution layer upgrade is complete, there will still be UCI building network equipment and cabling that requires upgrade over coming years. NACS will work with the administration to determine a funding source and timeline for these projects.

Apple has donated to UCI a small computational cluster based on its XServe product line.
This three-server cluster (two computational nodes and one control or “head” node) is built on the PowerPC chip. Each node features two 2Ghz PPC CPUs. The cluster also offers a 1.2Tb (1200 Gigabytes) disk array. The PowerPC architecture features high-performance true 64-bit floating point arithmetic, and is particularly well-suited for floating point and vector calculations.
Originally, NACS and faculty evaluated batch processing systems for the cluster under the Macintosh OS X operating system. Currently the cluster is running Linux, because faculty tend to be more familiar with that operating system, and to take advantage of the richer software development environment available under Linux.
GNU compilers for C, C++, and Fortran are available on the cluster, as well as the optimized IBM C/C++ compiler suite for PowerPC. Faculty may contact NACS for accounts, assistance with porting, and benchmarking.

NACS hosted a half-day of hands-on training on communications cable installation on Thursday, March 31st. The class participants included fifteen UCI staff.
Gary Price, RCDD, of Nelson & Associates provided the Outside Plant electrical protection training. Wayne Brushett of Beach Wire and Cable, Inc., arranged for instructors from Superior Essex Communications LP.
The focus of the class was Outside Plant Copper Splicing and Outside Plant Fiber Optic Cable. Outside Plant cabling is installed in conduits below the ground which connects all of the buildings together and comprises the “backbone” of UCInet, the campus network.
