Mass Storage
•
•
•
•
long term archival storage
easy to access and use
“limitless” capacity
looks like ordinary disk file
system – data is actually
stored on tape
• data is backed up
“To infinity … and beyond”

Virtual Computing Lab (VCL)


Collaboration with NC State to establish VCL infrastructure for
UNC.
VCL provides on-demand access to high-end computing
resources, via highly customized, virtual Windows and Linux
machines.
Virtual Computing Lab (VCL)
• Users can log on from anywhere at any time to make
a reservation to use a machine
• Lots of software available!
ArcGIS
 SAS
 MATLAB
 Adobe
 MS Office
 LaTEX
 SigmaPlot
 MUCH MORE!

Access to National Resources
• XSEDE – NSF funded
leadership class
infrastructure at 11
partner sites.
• Open Science Grid –
national shared
computing and storage
resources in a common
grid infrastructure

personal consultation
Engagement, Support and Collaboration
• Research scientists with experience in
computational chemistry, physics, grid
computing, environmental modeling,
mathematics, parallel computing and
the life sciences are available for
consultation and collaboration.
• Digital Humanities Specialist
• Extensive technical support for utilizing
research computing resources.
Services: Secure Data Exchange
• Capability to share secure and sensitive data
using a secure “drop box” mechanism for
anonymous or non-Onyen users or full FTP access
for trusted Onyen accounts
• Computing - challenges of flexibility needed for
research and realities of cyber attacks
• Networking – maximizing bandwidth for research
endeavors vs. IPS/IDS inspection
• Data – compliance requirements,
data sharing, privacy, etc.
Services: Data Grids –iRODS
• Distributed data storage using the integrated Rule oriented
Data System (iRodS). iRODS provides scientists with a
secure, scalable system that can support many aspects of
research data management
• Enables data grids/repositories whose policies are
implemented and enforced through rules
Research Computing is
experimenting with hosting iRODS
collections as a service.
Collaborating with UNC Libraries,
Institute for the Environment, and
RENCI.
