Oracle RAC performance
Hello all,
I have a 3 node oracle RAC. Each server has 2 intel quad core processors. I was asked to extend the RAC to 5 nodes to increase the processing power. I was told that Intel 6 core processors are in the market. So I was looking at the following options and need your input/expertise or suggestions on the following options.
Option 1: Add 2 more nodes with 2 quad core processors to the existing 3 node RAC. so total cores available to process the load will be 40 cores.
Option 2: completely replace all the above 5 nodes(in option 1) with 4 nodes - each with 2 * 6 core processors. total cores available are 48 core.
option 2 will give have 1 less server to maintain.
will the performance on option 2 be better than option 1? Any there any white papers or documentation to help me take a decision as to which option i should go?
Thanks in advance.
