I use lvm in a mainframe environment, with small ECKD disks (maximum model

going to create one with 35 physical volumes. I have doubts about striping,
particularly deciding the number of stripes in such case (35 PVs in one
storage array rank -yeah, not good-), and the drawbacks in administration
tasks ( growing and limitations adding pvs to a stripped volume).

The use of striping is recommended because of performance improvement:
