With multicore processors and virtualization pushing blade-server performance to unprecedented levels, I/O performance must catch up—but without increasing cost per port or power consumption. The only way to meet this goal is to use more highly integrated network switch chips that provide higher throughput per port.

Because today’s multicore processors utilize the 8- to 10-Gbps PCI Express I/O bus, blade servers can easily benefit from the throughput provided by 10-Gbps Ethernet (10GbE). The evolution of Ethernet standards has made 10GbE switches the ideal technology for meeting the wide range of requirements in today’s converged data centers.
