Abstract
JUST is a versatile storage infrastructure operated by the Jülich Supercomputing Centre at Forschungszentrum Jülich. The system provides high-performance and high-capacity storage resources for the supercomputer facility. Recently, additional storage and management services, addressing demands beyond the high-performance computing area, have been added. In support of its mission, JUST consists of multiple storage tiers with different performance and functional characteristics to cover the entire data lifecycle.
Highlights
The JUST (Jülich Storage) cluster is a large-scale storage infrastructure operated by the Jülich Supercomputing Centre (JSC) at Forschungszentrum Jülich (Forschungszentrum Jülich, 2019)
A share of the system is funded by the German Ministry of Education and Science (Bundesministerium für Bildung und Forschung – BMBF) and the Ministry for Culture and Science of the State North RhineWestphalia (Ministerium für Kultur und Wissenschaft des Landes Nordrhein-Westfalen – MKW) via the Gauss Centre for Supercomputing (GCS)
The IBM Spectrum Protect server instances are hosted on eight Power 8 servers, each connected with four 16 Gb/s FC links to the central Storage Area Network (SAN) switches
Summary
The JUST (Jülich Storage) cluster is a large-scale storage infrastructure operated by the Jülich Supercomputing Centre (JSC) at Forschungszentrum Jülich (Forschungszentrum Jülich, 2019). Installed in its fth hardware and software generation, JUST has evolved from a dedicated storage cluster for JSC’s leadership-class system to the central storage provider for the modular supercomputing facility at JSC. As such, it provides a variety of data-storage and management related services and is to be seen as a research infrastructure on its own. A share of the system is funded by the Helmholtz Association (Helmholtz Association, 2019b) through the program "Supercomputing & Big Data" and the Helmholtz Data Federation initiative (Helmholtz Association, 2019a)
