More information on the results is available at http://www.microsoft.com/presspass/events/HHHlaunch/docs/BenchmarkFS.docThe result demonstrates the scale-up capabilities of SQL Server 2008 on HP Integrity. The 10TB benchmark is so demanding that only six other results have been published in the nine-year history of TPC-H.
