    The EVN directors have agreed that each of the “busy” EVN station should provide at least 150 TB to the EVN disk pool. The other stations should contribute about 2 times the amount of disk space which is recorded at their thelescope per session.

    1) 10 Modules with 4 disks a 1.5 TB

    Note:

    • Effelsberg: Will remove all our small modules with less than 2 TB. (April 2010)
    • Effelsberg: Will try to avoid sending modules smaller than 3.2 TB. (January 2011)
    • 2 TB disks can only be handled with SDK8.2 and SDK8.3 with patch applied.
    • Modules bigger than 8 TB require SDK 9 which is not yet officially supported for field operation.

    ASTRO / GEO VSN assignments at EVN stations

    The information below may be out of date. Please update!!

    • HART-001 thru HART-020 are IVS 8-packs
    • HART-021 thru HART-050 are EVN 8-packs
    • Medicina, label number above 1000 are geo modules, below are astro module (ie med-1001 stands for geo modules).
    • Noto: Geo/Astro split unknown
    • Onsala: Astro disks have a VSN number below 100, so it will look something like this: OSOD-001
    • Onsala Geo disks have a VSN number above 100, so it will look something like this: OSOD-101
       
    • Yebes astrodisks have a VSN number below 100: OAN-00xx (PATA) and OAN+00xx (SATA, up to OAN+0025)
    • Yebes geodesy disks have a VSN number above 100: OAN-01xx
    • SHAO: Geo/Astro split unknown
    • UAO: Geo/Astro split unknown
