CIOs, therefore, look for ways not just to keep the CPU utilization high, but also to verify that the expensive CPU cycles are being used to run applications and not being wasted on communications and data transport functions that can be better handled by more efficient networking components. Modern data centers have been using advanced networking controllers and cards to offload jobs from running on the CPU to running on the networking controller.Using advanced networking technologies to maximize the application efficiency of the CPU results in a reduction in the idle time of other expensive server resources, such as memory or Solid State Disks (SSD), and helps to increase the overall server efficiency, enabling faster job completion and less power consumption. This trend is expected to continue to grow, and that the industry will soon see more advanced IO controllers and Network Interface Cards (NICs) with onboard Field-Programmable Gate Array (FPGA) devices. This will enable CIOs to react faster to a new business needs and to add new functionality without the need to pay for new servers or for more expensive CPUs. This will extend the life of the company's cloud infrastructure and maximize its Return on Investment (ROI). As cloud computing has become an integral part of enterprise operations, CIOs must continue to deploy the most efficient solutions. The traditional architectures that have been developed over old networking technologies can no longer keep up with the new business requirements. Modern interconnect technologies enable the deployment of modern cloud architectures that deliver higher functionality and reduce CapEx and OpEx. As cloud continues to play a major role in the future, interconnect capabilities will remain an essential factor in maintaining higher efficiency.clouds that can serve mobile users world-wide.The de-cou-pling concept has been so successful that it has also been adopted by the tele-com industry to ensure less expensive equip-ment deployment. All these solutions re-quire the most mod-ern networking in order to provide the functions that are re-quired when SDN architec-ture is deployed. One of the lead SDN products is VM-ware's NSX platform which reproduces the entire network model in software and enables any network topology and services in seconds. Those capabilities rely on having the right interconnect products that can be programmed to enable agility and economics that help CIOs to achieve higher operational efficiency through full automation.Another area in which new networking technologies achieve higher efficiency is by maximizing CPU resources actually running applications. CPUs are among the most expensive items on a server, and on average in a standard dual-socket server, CPUs make up more than 50 percent of the total server
