VME is a bus standard for backplanes.

SCSI is a standard for a "distributed bus", ie the peripherals are
all at the end of cables.

You would not want the sole link between a memory card and the CPU
to be a SCSI bus.  But SCSI works well for mass storage, printers
and scanners.

It is popular because it is faster than most peripherals, so you don't
loose performance in your bus.
