LU size expansion
The LU Size Expansion (LUSE) feature allows you to create volumes that
are larger than standard OPEN-x LDEVs. This capability enables hosts to
access the data in the array using fewer logical units. The following tables
list the OPEN-x sizes, LUSE size limitations, and (for comparison) VSC
size limitations. VSC volumes may also be used with LUSE.
