Where I work, been here for twenty years, and in all that twenty years I have been told we are going to do away with the mainframe which is a Z series. Of course we have been told the same about the i series which is actually larger. What have we done in the last year alone, gone to the Z-14 and a 32-way 870 i. seriously people underestimate the cost to move off a platform that is working and worse when there are so many touch points no one can seem to get an accurate handle on them all. IBM does indeed take their reliability seriously, both i and Z are all built around not having any downtime but the Z does do it better than i which still can require it for patches. i just find it fascinating the work that we use these machines for and how instead of being replaced more work lands on them because of reliability issues of other platforms. That and support requirements of other platforms. The z and i teams are three man admin with a few operators to nod heads... the other platforms seem to have armies
