Rack
- A group of inter connected nodes is called Rack.
- A rack can be collection of 30 to 40 nodes.
- Within rack nodes communication is very fast than different racks nodes communication.
- Within rack nodes means, communication between Rack1/Node1 and Rack1/Node2 is very fast.
- Different rack nodes means, communication between Rack1/Node1 and Rack2/Node1 is a bit slow.
