[76.01] How Many Terabytes Was That? Archiving and Serving Solar Space Data Without Losing Your Shirt

Even solar missions of modest size in the next decade will produce terabytes (1012 byte) of data. The Solar Data Analysis Center is already dealing with mission archives of similar volumes, and is serving the entire archives to the community over the Internet.

We examine present and near-term archiving strategies and media, and conclude rather surprisingly that online storage on network-attached RAID arrays is the most cost-effective, as well as the most usable, archiving method likely to be available over the next decade for keeping and serving scientifically useful data for a period of 10 years or more.
