Q. Is power better in a data center? A. Yes. Energy is another important issue for every data center to review. In a data center, power is closely managed and monitored. Often multiple power grid connections and redundant power wiring is used to ensure high availability of power to network resources such as servers, routers, and switches. Per-rack power requirements constrain the number of racks a data center can support. A typical 10,000 - 20,000 sq. ft. facility designed for 50 - 100 watts/sq. ft requires 1/2 megawatt to 2 megawatts of power. Availability and cost of utility power in the megawatt range is expensive and difficult to obtain. Supporting infrastructure - generators, ATS, UPS, and distribution equipment - also are costly. Careful planning and growth projections must be maintained to ensure power requirements can be met. Data center managers should implement improvements to your facilities. for example, raise the temperature of the data center and use energy management software. Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. Virtualization can be viewed as part of an overall trend in enterprise IT that includes autonomic computing, a scenario in which the IT environment will be able to manage itself based on perceived activity, and utility computing, in which computer processing power is seen as a utility that clients can pay for only as needed. Application virtualization separates applications from the hardware and the operating system, putting them in a container that can be relocated without disrupting other systems. If users are to embrace client backup, the backup process must be transparent. Users must be able to continue to work with little or no interruption. There must be protection while the computer is disconnected from the network, and there must be automatic storage management synchronisation when the computer is reconnected to the network. New or changed data should be replicated immediately to the disk drive whenever a file is saved or closed. The Cisco UCS uses three adapter types, with four specific models: the Cisco UCS 82598KR-CI 10 Gigabit Ethernet Adapter, UCS M71KR-Q QLogic Converged Network Adapter, UCS M71KR-E Emulex Converged Network Adapter, and UCS M81KR Virtual Interface Card. Each of these cards has a pair of 10 Gigabit Ethernet connections to the Cisco Unified Computing System backplane that support the IEEE 802.1 Data Center Bridging function (formerly called Cisco Data Center Ethernet) to facilitate I/O unification within these adapters. On each adapter type, one of these backplane ports is connected through 10GBASE-KR to the A-side I/O module; then that connection goes to the A-side fabric interconnect. 10GBASE-KR is a copper midplane technology for interfacing adapters and switching elements through these midplanes. The other connection is 10GBASE-KR to the B-side I/O module; that connection then goes to the B-side fabric interconnect. Figure 3 later in this document shows this connectivity. Green IT refers to the study and practice of using computers and IT resources in a more efficient and environmentally responsible way. An High Availability Data solution must be practical to implement - minimizing acquisition cost and operational complexity while being able to efficiently scale-out to meet any performance requirement as business needs evolve. 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. |
