Re: Larry Ellison comments on Microsoft's benchmark

are you saying mutual takeover is impossible ? This is quite possible such as implemented by teradata. They use raid configuration for the disk (2x disk requirements) and if you have a processor failure, the data is processed by the backup. They implement by a group of machines -- normally 4 so you have 3 nodes that are doing 33% more work than they normally do.
