Target for LOFAR Long Term Archive: Architecture and Implementation

TL;DR

This paper details the architecture and implementation of the LOFAR Long-Term Archive, a large-scale data storage system adapted from the WISE concept to handle LOFAR telescope data.

Contribution

It presents the adaptation of the WISE-based Astro-WISE information system for LOFAR's extensive data storage needs, demonstrating scalability and customization.

Findings

Successful implementation of a multi-Petabyte data archive

Adaptation of WISE concept for LOFAR data management

Enhanced data handling for large-scale astronomical data

Abstract

The LOFAR Long-Term Archive (LTA) is a multi-Petabyte scale data storage for the processed data of LOFAR telescope. We describe the adaptation of the WISE concept implemented by Target consortium for the LOFAR LTA and changes we introduced to it to accommodate LOFAR data. This paper describes an example of a new information system created on the basis of Astro-WISE for a wider range and scale of data.
