Hardware clustering (sometimes called operating system clustering) is a hardware-based method of turning multiple servers into a cluster (a group of servers that acts like a single system).As a rule, a hardware cluster is created by installing a number of blade server s on the machine that will control the cluster.Each of the blade servers functions independently of the others, although they all respond to the same requests.s a rule, a hardware cluster is created by installing a number of blade server s on the machine that will control the cluster.
