This is both striping via 2 different, supported device-mapper targets, 
'striped' and 'raid'
('striped' is  an older, separate target and  'raid0' is supported by 
the 'raid' target which
  also supports raid1/raid4/raid5/raid6 and raid10).

The algorithm to distribute data on the stripes is the same for both 
striped and raid0
and they can be converted into each other running 'lvconvert --type 
striped|raid0 $LV'
since raid target version 1.7.0 / lvm2 version 2.02.155.

See lvmraid(7) for insight into the RAID support in lvm including the 
aforementioned
and many more conversions from and to RAID and between RAID levels and 
layouts..
