Featured Solution: Cisco Unified CommunicationsOperating a data center at peak efficiency and reliability requires the combined efforts of facilities and IT. 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. There are 10 key issues for IT managers to keep up with: virtualization; the data deluge; energy and green IT; complex resource tracking; consumerization of IT and social software; unified communications; mobile and wireless; system density; mashups and portals; and cloud computing. 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. The idea is that virtualization disguises the true complexity of the network by separating it into manageable parts, much like your partitioned hard drive makes it easier to manage your files. Businesses spend a lot of money powering unused server capacity. Virtualization reduces the number of physical servers, reducing the energy required to power and cool them. 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. Some functions in the Cisco Unified Computing System are similar to those offered by the Cisco Nexus 1000V Series Switches, but with a different set of applications and design scenarios. The Cisco Unified Computing System offers the capability to present adapters to physical and (in the near future) virtual machines directly. When presented to the virtual machines, VN-Link technology can provide many of the same benefits as those described for the Cisco Nexus 1000V Series. Green IT facilities offer employees a healthy, comfortable work environment. In addition, green facilities enhance relations with local communities. High availability data systems optimize the reliability of data storage systems by providing redundancy only of critical components to eliminate single points of failure. A single point of failure occurs when the failure of a single component of a system causes the entire system to cease operating, resulting in the potential loss of data. Therefore, one goal in designing a high availability data storage system is to provide a satisfactory level of reliability while keeping the cost of the system in check. 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. |
