Q. What is a data center? A. A data center is where the majority of an enterprise servers and storage are located, operated and managed. How exhaust air is returned to the cooling units within the data center is as important a consideration as the distribution of cool air to the servers. Hot aisle and cold aisle techniques must be extended to include evaluation of airflow dynamics. At higher power densities the amount of space required to house cooling equipment will overtake the number of cabinets. Alternate approaches, or a reduction in the amount of equipment housed in each cabinet, must be considered. Energy costs are the fastest-rising cost element in the data center cost portfolio. In-house data centers can be a business weak link if proper attention isn’t paid to power use, cooling capacity, disaster recovery preparedness, running IT to support compliance initiatives, and staffing flexibility to support utility computing initiatives. 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. Companies often run just one application per server because they don’t want to risk the possibility that one application will crash and bring down another on the same machine. Estimates indicate that most x86 servers are running at an average of only 10 to 15 percent of total capacity. With virtualization, you can turn a single purpose server into a multi-tasking one, and turn multiple servers into a computing pool that can adapt more flexibly to changing workloads. Many IT departments encourage users to save critical data to available network servers under the control of enterprise software. This policy, in most cases, is not successful, since users store data locally, especially mobile users who are seldom connected to a network. The Cisco UCS integrates low-latency unified network fabric with enterprise-class, x86-based servers, creating an integrated, scalable, multichassis platform in which all resources participate in a unified management domain. A single system scales to up to 40 chassis, 320 compute nodes, and thousands of virtual machines. Green IT facilities offer employees a healthy, comfortable work environment. In addition, green facilities enhance relations with local communities. Data storage systems are used in a variety of businesses for the purpose of storing and maintaining data which is critical to the operation of the businesses and their customers. It is very important that such data storage systems be highlyreliable to minimize or eliminate the chance of losing data if the system fails. The most secure and reliable systems employ total redundancy, in which every component of the system is replicated, such that, upon a failure of a component, anothercomponent takes over operation, so that the data storage system can remain fully functional. For example, two storage processors may be provided in a system such that if one fails, the other assumes the operation of the failed processor as well asmaintaining its own. However, total redundancy is expensive and can be an inefficient use of system resources. The Cisco Nexus 5010 Switch foundation is built upon High-performance 10 Gigabit Ethernet, Data Center Ethernet, Fibre Channel over Ethernet (FCoE), and Virtual-machine-optimized networking. |
