Abstract :
The notion of a single server architecture is, however, beginning to fade as data-centre users focus on squeezing more performance per-watt out of their systems. Although they employ a Linux core, the servers operated by companies such as Google have been heavily customised. Also many server users are questioning whether reliance on one type of processor (no matter how accomplished it is) is altogether wise - putting a much greater focus on how data moves through the system.
