RE: concepts document part about separating indexes and tablespaces

Greetings,  

I suspect this may date back to the "old days." I remember some years ago a statement, I believe it was in an Oracle Press book on oracle administration, that the ideal number of disks for a database was 28
(maybe not that many but close). This was in days when disks were
smaller and performed differently. The idea was to spread things out across several disks, data, indexes, online redo logs, archive logs, undo, temp space, etc. so that I/O bottlenecks would be minimized. With today's faster and bigger (huger actually) disks this is not only less of an issue but difficult to do. How can you do that on a machine with 1 500GB disk? Why?  

Thanks.

If it says that, someone should file a documentation bug to get it fixed.

i was talking to someone about this today. I cannot remember where in
the Concepts document that it says that separating data from indexes
improves performances?
