Large-scale scientific data and long-term data storage function in a computing center

Long-term data storing is an important task for many modern scientific laboratories and datacenters. In order to reduce cost of digital information ownership, some solutions use magnetic tape technology special software control medium data. Considering the on-site infrastructure specifics well-established workflows processing, these organizations build support such systems mainly by their own efforts, what becomes in seeking acquire technological sovereignty. This paper describes long-term storage issues computing center Zababakhin All-Russia Research Institute Technical Physics where mathematical modeling computations generate vast amount The architecture functional composition developed Archive Data Storage System are given as well its internal model, chunk grouping rules, low-level format used. measures taken ensure archived consistency, methods media management archival fund maintenance, also considered. calculation scheme a typical archive system site’s hardware configuration, sufficient process archiving flows existing datacenter, given.
