As for the future LOFAR system, the CS1 storage capacity is too small to store all data in a central location indefinitely. Moreover, the central storage location needs to provide storage not only for observation datasets, but also for (temporary) commissioning and analysis data. The policy below has been defined to allow efficient use of the offline storage cluster while providing as much support to people involved in the commissioning of LOAR CS1 as possible. | As for the future LOFAR system, the CS1 storage capacity is too small to store all data in a central location indefinitely.

Requests should be directed to the observer on duty (observer at aston dot nl). The request should be accompanied by the capacity needed. Further information may be requested (such as motivation, expected period for which storage capacity is needed, etc). |
