split returns an array
(http://ruby-doc.org/core-1.8.7/classes/String.html#M000776). So you
can do the following:

nodes.each do |node|
  m = node.match(/(.*?)\[(\d+)\.\.(\d+)\](.*)/)
  if m
    (m[2].to_i..m[3].to_i).each {|num|
do_something_with("#{m[1]}#{num}#{m[4]}")}
  else
    do_something_with(node)
  end
end

This will call do_something_with passing either each expanded server
name or the original string if it doesn't match the regular
expression.
