Re: Exadata X4 vs. X5 DB node CPU comparison

This is a follow-up to my past entry.

Exadata X4 vs. X5 DB node CPU comparison (INOUE Katsumi @ Tokyo)

Now with Database In-Memory, DB node's CPU and memory specs more directly influences DB performance.

Firstly, HW spec is not the only change going from X4-2 -> X5-2.
I heard default kernel parameter is changed which will influence performance.
There may be kernel code change for performance, too.

Secondly, our product manager wrote about related info here.

Do I still need Exadata now that I have Oracle Database In-Memory? (Oracle Database In-Memory)

  • You get a complete fault-tolerant In-Memory solution
