Q. What can happen if an application fails? A. When a device, connection or application fails, it can take down mission critical operations. Sometimes, one systems failure will cascade to applications on other systems that rely on the data or services from the failed unit. Power continues to lead as a concern for data center operations. Data centers are designed to a specific power density - watts per square foot - with a typical cabinet of equipment occupying 14 sq. ft. of space. Implement virtualization quickly, and plan to have at least 50 percent of x86 data center servers virtualized by 2011 to improve asset use and to lower energy costs. Beyond backup and recovery protection, ensuring maximum data center availability and uptime is clearly crucial to a business’s success. Business Continuity seldom goes beyond the planning stage at most companies, however, until downtime or data loss hit. Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others, and each of which can be assigned (or reassigned) to a particular server or device in real time. While virtualization faded from the limelight for a while, it is now one of the hottest trends in the industry again, as organizations aim to increase the utilization, flexibility and cost-effectiveness in a distributed computing environment. VMWare, Citrix, Microsoft, IBM, RedHat and many other vendors offer virtualization solutions. A storage management solution should address the protection of recoverable as well as unrecoverable information. The need to protect unrecoverable data is obvious — unless this data is protected, it must be manually recreated if it is lost. As for recoverable data, although it may be recoverable through reinstallation, the process can be extremely time-consuming and costly. To reinstall an updated application, users must install the application plus all the updates. In addition, all preferences and options need to be reset to their exact state prior to the loss. With the Cisco UCS M81KR adapter, multiple virtual interfaces (VIFs) can be identified to match those used by the service console, VMware VMkernel, virtual machine data, Cisco Nexus 1000V Series VLANs, etc. as required. Each of these adapters can be defined within the Cisco Unified Computing System as connected to an individual fabric interconnect and, optionally, enabling a failover to the other. Building green IT systems do come with an added cost. These systems do need to take into account the overall short and long term sustainability, the total cost of ownership and the costs of safe recycling and disposal. But when used with efficient and effective policies, the return on investment can be much greater for the organization, employees and the community. 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. Next-generation data centers have specific server networking needs, and the Cisco Nexus 5010 one-rack unit (RU) switch provides an Ethernet-based unified fabric that's designed to meet those needs. |
