Evolution of Archive Technologies at the National Snow and Ice Data CenterPresented at the THIC Conference, Boulder CO, July 19-20, 2005
A brief history of NSIDC
• World Data Center for Glaciology 1957 - U.S. National Committee for the IGY awarded
the operation of WDC-A for Glaciology to the American Geographical Society under the direction of Dr. William O. Field
1970 - WDC for Glaciology transferred to the U.S. Geological Survey in Tacoma, Washington under the direction of Dr. Mark F. Meier
1976 - WDC for Glaciology transfers to the NOAA Environmental Data and Information Service; an agreement between the University of Colorado and NOAA placed the WDC at CU-Boulder, Colorado under the direction of Roger Barry

COPAN MAID - Early Experiences
• Using AMASS to provide a file system front end to a COPAN 200t system configured as a L700 with 7 - 9940 drives COPAN to act as a drop-in replacement for the
STK 9710• Migration of data underway • The big surprise was performance• Minor surprise is the ever shrinking total
archive size

Evolution of Archive Technologies at the National Snow and Ice Data CenterPresented at the THIC Conference, Boulder CO, July 19-20, 2005
Thoughts on the Future
• NSIDC DAAC is pushing for an entirely on-line archive What technologies will allow this? (SATA
RAID, COPAN, or ???) What happens to media? How do we ensure preservation of these data
over time?
