Chances are that if you understand what you want the solution will

As others have said: store in an Array.  I don't know what
current_result refers to but it looks like something like this could
work:

current_first = linecount.times.map {|i|
current_result["#{server_name}-#{i + 1}"]["usable"]}

Assuming we have current_first and current_second then you could just do

current_first == current_second

Kind regards
