ODA- Oracle Database Appliance X4-2 node information

If we know the power of the underlying hardware, we can confiure our nodes better to achive the best performance and to have a better utilization..
Here is the specs of a ODA x4-2 node.. Note that, in a node, we have  2 cpus , 12 cores and 2 threads per core. So Hyper Threading is enabled. This makes 48 virtual cores..
Also, we have 256 gb memory per node and We use 2.6.39-4000 uek smp kernel with xen.
