No. device-mapper is the LVM component that supports concatenation or
PE strip-like distribution (kinda RAID-0). LVM bt itself is no
pseudo-RAID, it's a Logical Volume Manager. Whether device-mapper
supports linear, concat or strip-like is another history. Most of the
production systems I manage use software RAID-0 (MD) and LVM on top of
it.
