Operating a data center at peak efficiency and reliability requires the combined efforts of facilities and IT staff. In a data center, servers, storage and network devices must be properly maintained and upgraded. This includes operating systems, security patches, applications and system resources such as memory, storage and CPUs. Hardware assets should be used well after their depreciated financial life has ended — for as long as is technically possible. Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. The usual goal of virtualization is to centralize administrative tasks while improving scalability and work loads. Virtualization was first introduced in the 1960s by IBM to boost utilization of large, expensive mainframe systems by partitioning them into logical, separate virtual machines that could run multiple applications and processes at the same time. In the 1980s and 1990s, this centrally shared mainframe model gave way to a distributed, client-server computing model, in which many low-cost x86 servers and desktops independently run specific applications. The cost of restoring the lost information or restoring a computer to operation after a hardware or software failure is high due to the costs of technical support and lost employee productivity. The Cisco Unified Computing System streamlines data center resources to reduce total cost of ownership, scales service delivery to increase business agility, and radically reduces the number of devices requiring setup, management, power, cooling, and cabling. The Green IT approach can include several different phases in the lifecycle of a product – the development, production, usage and disposal of IT. Development must grant consideration to the environment; the production must take place using environmentally friendly production methods; the IT solutions must be used in an environmentally friendly manner; and finally, IT waste must be disposed of in an environmentally correct manner. All of these phases are supported by research and innovation in Green IT. High availability is a system design protocol and associated implementation that ensures a certain degree of operational continuity during a given measurement period. The Nexus 1000V switch is a software switch on a server that delivers Cisco VN-Link services to virtual machines hosted on that server. It takes advantage of the VMware vSphere framework to offer tight integration between server and network environments and help ensure consistent, policy-based network capabilities to all servers in your data center. |
