VSAM, Partitioned Datasets and VTOCs for starters all depend on keyed
records. How well do these perform on VSE on FBA devices?

With the emulation the stuffing around needed is done off the host CPU
- I don't care a lot whether it's the channel or controller or the
device itself. I presume that for the FBA devices to be supported
directly then it would be done by the host CPU and people tell me it's
not that strong.

Of course, Linux would get along just fine with FBA devices, so the
option to attach sharks etc natively would clearly be of use.
