Cisco Nexus Switches - 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 centers are the biggest challenges facing IT executives in the coming years. Where possible, use outside free air as an alternative to expensive air conditioning. 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. Virtual machines offer many benefits: server consolidation, increased utilization and faster recovery times after failure. Virtualization was first introduced in the 1960s by IBM to boost utilization of large, expensive mainframe systems by partitioning them into logical, separate virtual machines that could run multiple applications and processes at the same time. In the 1980s and 1990s, this centrally shared mainframe model gave way to a distributed, client-server computing model, in which many low-cost x86 servers and desktops independently run specific applications. 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. Both small businesses and global enterprises have users all over the world who require access to data 24 hours a day. Without this data access, revenue and customers can be lost, penalties can be owed, and bad press can have a lasting effect on customers and a company's reputation. Building a high availability IT infrastructure is critical to the success and well being of all enterprises in today's fast moving economy. 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. |
