A Performance Study of the BIMA Archiving System
نویسنده
چکیده
I present results of a study of the BIMA archiving system in an effort to measure the typical rates at which data is transferred from Hat Creek to NCSA for archiving. This was done by altering the archiving software at Hat Creek to measure data transfer times as the data is sent to the archive server. The average archiving rate over a two week period was found to be about 350 kilobits per second with large variations between 200 and 700 kilobits per second. Internet traffic was found to be the primary limiting factor to the archiving rate over software overhead and competition for local system resources. The results are used to make recommendations for limits to be placed on the data production rate to ensure that the archiving system can keep up.
