Arcturus is a big big SPARC server. It was received through the 2008 Sun AEG received by the TJ CSL. Simply put, arcturus is a high-performance computing (HPC) server. It is also a Sun Ray server for HPC projects (separate from the primary Sun Ray FailOver Group (FOG)). Arcturus also has a LUN on the SAN to facilitate storage of HPC and research data off of AFS.

IMPORTANT: The power supplies are not redundant unless they are running at 208V and configured to be redundant. We are currently running them at 120V. Do not unplug either power cord without powering arcturus off first!


  • HPC (including Matlab, possibly Mathematica in the future)
  • Boot server for Solaris net installs (this may move to a different server later)
  • Development/compile server for SPARC (similar to betelgeuse, but more stable by necessity)

Arcturus replaced moloch. While it does not have hot swap CPU and memory boards like moloch did, just about every other part except the DVD player is hot-swappable, even the PCIe and PCI-X slots. It also pulls less power than moloch (idle vs. idle). Arcturus' CPUs can be upgraded to the newer SPARC64-VII (2.4 Ghz, 4 core, 2 threads/core) processors should we ever want to and can afford to.
