Data Backup - Call PBM IT Solutions at (888) 233-6471Q. What is a data center? A. A data center is where the majority of an enterprise servers and storage are located, operated and managed. Data center per-cabinet power consumption has steadily increased over the past several years as pedestal servers drawing 1KW/rack have given way to 1U/2U pizza box servers at 3.5KW/cabinet and blade implementations at 10KW/cabinet. Faster CPUs, larger memory chips, and smaller disk drives also continue to increase power demands. Gradually raise the temperature at the server inlet point to run up to 24 degrees Celsius (75 degrees Fahrenheit), but use sensors to monitor hot spots and supplementary cooling, if required. Most line of business managers take for granted 100 percent IT up time, instant access to trained support personnel, uninterrupted access to data, and are dependent on top-flight management of IT assets in data centers. 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. Different virtual machines can run different operating systems and multiple applications while sharing the resources of a single physical computer. And, because each virtual machine is isolated from other virtualized machines, if one crashes, it does not affect the others. One of the greatest challenges facing IT professionals is effectively protecting business critical information, particularly the growing amount of data stored on distributed desktops, remote and laptop computers. New computing resources can be deployed in a just-in-time approach. Traditional physical and virtual workloads can be easily migrated between servers through remote management, regardless of physical connectivity. The Cisco Unified Computing System improves availability, security, agility, and performance through an integrated architecture. The recent attention on Green IT technologies has opened new career opportunities for IT professionals. Since some of the areas need specialized attention such as energy efficiency, environmental laws and ethical disposal, some organizations have created new positions and divisions to embrace this upcoming trend. An effective High Availability (HA) data solution must address both unplanned and planned causes of downtime to achieve a truly fault tolerant and resilient IT infrastructure. Unplanned downtime is primarily the result of computer failures, data failures and human error. Planned downtime is primarily due to data changes or system changes that must be applied to the production system. The Cisco Nexus 1000V provides real-time coordinated configuration of network and security services and maintains a virtual machine-centric management model, enabling the server administrator to increase both efficiency and flexibility. |
