I'd use a Hash of Arrayrefs.
use Modern::Perl;
use Data::Dump qw /dump/;
my %hash;

while (<DATA>) {
    chomp;
    my ($item, $sequence, $value) = m/(aixFsMountPoint|aixFsSize|aixFs
+Free)\.(\d+)\s=\s"?([^"]*)/;
    next unless $item;
    $hash{$item}[$sequence] = $value;
}

say dump(\%hash);

__DATA__

actual STDOUT:

Of course, whether such datastructure is useful or not will ultimately depend on what you want to do with the data.

CountZero

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
