Q. What is the best place to run and monitor applications such as modem applications? A. Modern applications typically have a high degree of device and connection interdependence. Ensuring maximum uptime requires 24/7 monitoring of the applications, systems and key connections involved in all of an enterprises various workflows. The best place to run and monitor applications is in a data center. In data centers, businesses will continue to leverage the computing and storage infrastructure Managed Hosting operators have made large investments in, and derive increased cost savings and benefits by utilizing shared, highly available infrastructure. 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. Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. 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. In addition to using virtualization technology to partition one machine into several virtual machines, you can also use virtualization solutions to combine multiple physical resources into a single virtual resource. A good example of this is storage virtualization, where multiple network storage resources are pooled into what appears as a single storage device for easier and more efficient management of these resources. While you might think that the chances of having a major loss of data on your computer or even having your entire computer crash are very small, disasters happen and it is always best to prepare for the worst, especially when it comes to something as irreplaceable as your files. The Cisco UCS uses three adapter types, with four specific models: the Cisco UCS 82598KR-CI 10 Gigabit Ethernet Adapter, UCS M71KR-Q QLogic Converged Network Adapter, UCS M71KR-E Emulex Converged Network Adapter, and UCS M81KR Virtual Interface Card. Each of these cards has a pair of 10 Gigabit Ethernet connections to the Cisco Unified Computing System backplane that support the IEEE 802.1 Data Center Bridging function (formerly called Cisco Data Center Ethernet) to facilitate I/O unification within these adapters. On each adapter type, one of these backplane ports is connected through 10GBASE-KR to the A-side I/O module; then that connection goes to the A-side fabric interconnect. 10GBASE-KR is a copper midplane technology for interfacing adapters and switching elements through these midplanes. The other connection is 10GBASE-KR to the B-side I/O module; that connection then goes to the B-side fabric interconnect. Figure 3 later in this document shows this connectivity. There is growing pressure from environmentalists and, increasingly, the general public for governments to offer green incentives: monetary support for the creation and maintenance of ecologically responsible technologies. 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. Nexus sets the stage for converged Fibre Channel and Ethernet networks. The Nexus products will allow companies to consolidate their separate server and storage networking infrastructures onto one unified network fabric. |
