A few recent posts mentioning mainframes >and TPC benchmarks:
Are there any benchmarks available comparing a z series against a blade configuration doing the same work and comparing the cost per benchmark unit? Given the complexity of instruction sets for both Intel and the z series and the different nature of them, I agree with others that straight instruction speed comparisons may be meaningless. For example how much of the work for an i-o is done by the main processor on a blade versus on the z series? What is the MP effect on the blades versus the z series?
