iGrid - San Diego to KISTI

San Diego, California to Daejeon, South Korea
On September 27, we transported 1,717 GB of the BESTDR3 Sloan Digital Sky Survey astronomical dataset from the iGrid Conference in San Diego, Callifornia, USA, to the Korea Institute of Science and Technology Information (KISTI), in Daejeon, South Korea. The average transfer speed was 1,027 Mb/s with a median speed of 1,160 Mb/s.

The data was transferred disk-to-disk from an NCDM server on the iGrid 2005 Conference floor in San Diego, CA, USA to a machine at KISTI, in Daejeon, South Korea. The machine at San Diego machine was a dual AMD Opteron server with a 10 Gb/s network card. The KISTI machine was a dual 2.8 Ghz Xeon, also with a 10 Gb/s network card.

The data was transported from San Diego to KISTI over the 10 Gb/s GLORIAD network using NCDM's UDT transport protocol and NCDM's UDT Gateway.
