Another advantage of the mainframe is that you can connect disks to at least 16 processors. All 16 processors can have read/write access. z/OS knows how to manage this. There is no reason to conned the disks to a single server and then have the other processors go through the server that owns the disk.
When running 10,000 transactions per second 24/7 all year long, most of them performing updates, this is a very powerful feature. Been around for decades.

On a mainframe you can also add or replace processors and memory on the fly without a system outage.
There are a few more that I cannot think of, but it is all mostly SYSPROG stuff.
If anyone has a specific systems topic that they are interested please let me know and I will do my best. I am retired and have more free time than I know what to do with.
My neighbors have always noticed that I would rather help them with their chores than to do my own.
I figure that I became a Senior Sysprog when I ran out of people that could answer my questions. Only two of them are still alive.
