Description
The Brookhaven Computing Facility provides for the computing needs of the
RHIC experiments, supports the U.S. Tier 1 center for the ATLAS experiment
at the LHC and provides computing support for the LSST experiment. The
multi-purpose mission of the facility requires a complex computing infrastructure
to meet different requirements and can result in duplication of services with a
large number of single-purpose servers for narrowly-defined applications. The
facility is investigating potential applications of the open-source Xen
virtualization package to allow the consolidation of services and servers. This
presentation also discusses using Xen to virtualize the bulk of our Linux-based
computing cluster. This is being integrated with Condor, the dCache-managed
distributed storage system and the new multi-core CPU's to improve availability
and increase effective usage of our facility resources by virtualizing a wide
array of software support packages to meet the needs of various applications.
Virtualization support (both hardware and software) can be an important element
for efficient operations in a heterogeneous computing environment with
increasing reliance on distributed computing models.
