Multiple systems, such as inventory control, credit card processing, accounting and much more will be involved in a complex process such as eCommerce checkout. A failure in one will compromise all the others. A data center is the best environment for these complicated IT functions. 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. Data center and IT managers must pay sufficient attention to the process of measuring, monitoring and modeling energy use in data centers. 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. Server virtualization is the masking of server resources (including the number and identity of individual physical servers, processors, and operating systems) from server users. The intention is to spare the user from having to understand and manage complicated details of server resources while increasing resource sharing and utilization and maintaining the capacity to expand later. Virtualization can optimize fewer servers to run at higher performance levels. One of the greatest challenges facing IT professionals is effectively protecting business critical information, particularly the growing amount of data stored on distributed desktops, remote and laptop computers. 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. Just as the efficiency of an automobile depends on how it is driven, the efficiency of IT depends on how it is used. This is just as true for the private consumer as it is for the large corporation or public authority with large data centres and server rooms. 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 Cisco Nexus 1000V allows policy to move with a virtual machine during live migration ensuring persistent network, security, and storage compliance resulting in improved business continuance, performance management, and security compliance. |
