Memory Reliability

[Colin Allinson]

In all my years working with IBM mainframe systems I have never seen a memory failure that caused recognisable problems.

My understanding is that the internal redundancy, hardware checking and auto correct make such an event very unlikely - but how unlikely? Has anyone ever experienced such a problem?

If a problem did occur at the level that affected VM would it be more likely to bring VM down or just affect a specific user referencing the memory blocks with the problem ?
