Cost-conscious IT departments have adopted data center virtualization as a way to help increase efficiency and reduce total cost of ownership. As virtualized server and storage deployments increase, infrastructure components are evolving to keep pace. These collective enhancements promise unmatched data center efficiencies, but they pose new challenges too?including escalating network storage and I/O demands that are driving the data center framework toward 10 Gigabit Ethernet (10GbE) connectivity.Systems designed for virtualized environments, such as the Dell? PowerEdge? R710 server based on the multi-core Intel® Xeon® processor 5500 series architecture, can support a large number of virtual machines (VMs). The Intel Xeon processor 5500 series combines multiple processors with architectural features that allow for a high level of 10GbE scalability?including specifications designed to enable faster memory, faster interconnect architecture, and a faster PCI Express (PCIe) bus than previous generations.At the network interface, Intel 10GbE server adapters include Intel Virtualization Technology for Connectivity (VT-c)?which includes Intel Virtual Machine Device Queues (VMDq) and Intel Virtual Machine Direct Connect (VMDc)?to enhance I/O performance in virtualized environments. Intel 10GbE server adapters support Internet SCSI (iSCSI) storage area networks (SANs) as well as network attached storage (NAS). In the next generation, planned performance-enhancing features include Fibre Channel over Ethernet (FCoE) offloads and receive-side coalescing (RSC).Many elements of the dynamic 10GbE data center are already in place. The generation of servers based on the Intel Xeon processor 5500 series architecture enables the processing power and adaptability needed to support growing VM deployment without increasing power or space requirements, while Intel 10GbE server adapters are designed to take advantage of the capabilities of these platforms and provide the necessary I/O bandwidth for a truly dynamic data center.
