On Thursday, 03, Dezember 2009, 5 pm GMT it will be a webcast about "Why I/O and CPU, not Interconnect Speed, is Critical to RAC Performance"
Ever since cache fusion has been made write-write, it has been generally perceived that a very high interconnect speed is vital to the success of RAC performance. This is a myth. Much of the RAC performance depends heavily on the availability of CPU for the key processes as well as the effectiveness of the storage subsystem.
