Some/most IBM "channel controllers" (read disk controllers) were fairly programmable. At some points in time and with some configurations, it was faster to run things on them than in the mainframe. In other cases, it was faster to run "everything" on the mainframe. Some folks made a fairly good living moving parts of applications to and from channel controllers.
