9. DataTAG - EU FP6 Information Day - Brussels 25 March 20039 On February 27-28, a Terabyte of data was transferred by S. Ravot of Caltech between the Level3 PoP in Sunnyvale near SLAC and CERN through the TeraGrid router at StarLight from memory to memory as a single TCP/IP stream with 9KB Jumbo frames at a rate of 2.38 Gbps for 3700 seconds. This beat the former record by a factor of approximately 2.5, and used the US-CERN link at 96% efficiency. This is equivalent to: Transferring a full CD in 2.3 seconds (i.e. 1565 CDs/hour) Transferring 200 full length DVD movies in one hour (i.e. 1 DVD in 18 seconds) Intel 10GigE Data Transfer Trial European Commission
