Not true ....
The 3-year life cycle of X86 is ideal in current times when the cpu is following moore's law. Any upgrade to UNIX servers after 3-years is a gross compromise. For case the cost of upgrade of individual CPU & Memory is ridiculously high even by the UNIX box standards.
That is tru in X86 world too. Thats the reason there are less that 5% X86 servers that go under an upgrade cycle.( there is nothing that stops you from upgrading Intel servers , may be the socket/chipset get refreshed sooner than Unix platforms).
Don't get me wrong , I come from UNIX world, but there is so only much kool-aid that one can drink. There is 2% scenario where UNIX is suitable & then there is x86 platform.
Biting the hand that feeds IT
