Load 1TB in less than 1 hour

This project was done using SQL Server 2005 Enterprise Edition (with SP1 beta) using the BULK INSERT command with 60 parallel input files, each of approximately 16.67 GB. The best time I got was 50 minutes. Hewlett Packard was kind enough to loan me some time one night on the machine they use to do the TPC-H tests. It is an Itanium2 Superdome with 64 1.6GHZ 9M (Madison) CPUs. For the insert tests the system was equipped with 256GB of RAM. The HP SAN configuration is rated at 14GB per second throughput.
