I understand that, but what I don not understant yet
is the "Often we can't extend the end of the
I am completly new to SAN technologies, so, for me,
the EMC SAN is like a black box where I can create the
LUN but I do not know how it is create _insigth_ the
SAN so I do not know if I have close neighbors :-)
that avoid me grow the LUN
