The WEAVE spectrograph will be mounted at the 4.2-m WHT telescope and will provide millions of spectra in a 5-year program, starting early 2018. The access and retrieval of information will be through its dedicated archive, the WEAVE Archive System (WAS). This will be developed and maintained at the TNG2 premises on the same island as the WHT. Its structure foresees the main axes of scalability, virtualization, and high availability. We present here the first performances on a simulated data set of 20M spectra, using different architectures and hardware choices.STAMPAenConference paper10.1117/12.22313002-s2.0-85006469877000388804600066https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9913/1/WAS-the-data-archive-for-the-WEAVE-spectrograph/10.1117/12.2231300.short?SSO=12016SPIE.9913E..1XGFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
