I'm beginning to get it. Here are few quotes from article quote: The announcement of high-end servers by IBM and Hewlett-Packard this week won't halt declining Unix server sales as the onslaught of x86 servers continues, analysts said on Tuesday. quote: But even the new chips will have little effect on reviving the declining sales of Unix servers, analysts said. Customers are increasingly opting for servers based on x86 chips, which are getting more powerful and entering markets traditionally dominated by Unix servers. quote: A lot of customers are switching to x86 servers because of lower hardware and software costs attached to acquiring and maintaining the systems, said Jim McGregor, technology strategist at In-Stat. http://www.pcworld.com/businesscenter/article/188951/ibm_hp_servers_wont_stop_x86_onslaught_on_unix.html I guess this would also apply to supercomputers? I think it's also the reason behind Micrsoft decision to drop Itanium support quote: Why the change? The natural evolution of the x86 64-bit (’x64′) architecture has led to the creation of processors and servers which deliver the scalability and reliability needed for today’s ‘mission-critical’ workloads,’” [Dan] Reger wrote. “Just this week, both Intel and AMD have released new high core-count processors, and servers with eight or more x64 processors have now been announced by a full dozen server manufacturers. Such servers contain 64 to 96 processor cores, with more on the horizon.” http://insidehpc.com/2010/04/06/microsoft-drops-itanium-support/ -- This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
