(it is unclear whether clustered servers counted as a single server or not.) this compares with 417,000 risc servers (spread across all risc vendors) and 8.4 million x86 servers. idc reports that a total of 184,000 itanium-based systems were sold from 2001 through 2007. for the combined power/sparc/itanium systems market, idc reports that power captured 42% of revenue and sparc captured 32%, while itanium-based system revenue reached 26% in the second quarter of 2008.
