One of the revolutionary z17 design updates includes moving I/O functions from
FICON channel cards to the new on-chip DPU. So, how do you measure channel busy?
Well, it’s still there, it’s just calculated a bit differently. Don’t worry –
your existing Z machines can coexist quite comfortably with the z17 and there’s
no need to learn new ways to report these stats. Join Yamil and John as they
contrast the old and new approach and share live reports on how to measure any Z
machine.
