I am more conversant with IEC 61508 as compared to ISO 26262 as I am from Industrial controls back ground. Hence please pardon me if I say something wrong...I believe ISO 26262 has evolved from IEC 61508 but it is molded as per automotive safety requirements. As I understand, safety standards such as IEC 61508 are more concerned with how to detect and avoid systematic failures and how to detect random failures but not so concerned with reliability/availability. But as the fault tolerance increases with redundancy, achieving required SIL/ASIL levels get easier. Hence indirectly this promotes redundancy...in an essence...promotes fault tolerance architecture.
