Featured Solution: Cisco Data Center Design & ImplementationOperating a data center at peak efficiency and reliability requires the combined efforts of facilities and IT. How exhaust air is returned to the cooling units within the data center is as important a consideration as the distribution of cool air to the servers. Hot aisle and cold aisle techniques must be extended to include evaluation of airflow dynamics. At higher power densities the amount of space required to house cooling equipment will overtake the number of cabinets. Alternate approaches, or a reduction in the amount of equipment housed in each cabinet, must be considered. Develop a dashboard of data center energy-efficient metrics that provide appropriate data to different levels of IT and financial management. Recent changes to the Federal Rules of Civil Procedure put IT on the front lines for ensuring a business is complying with regulations, notably Sarbanes-Oxley and HIPAA. Not only is it necessary to store key data for longer periods, but being able to retrieve information at a granular level –right down to specific emails –is now an IT responsibility, one that if not handled properly could result in a vacation with the local municipal system. 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 isn not a magic bullet for everything. While many solutions are great candidates for running virtually, applications that need a lot of memory, processing power or input/output may be best left on a dedicated server. In many businesses, critical data is stored on desktop and laptop computers outside the reach of most enterprise storage management software products. This data is at significant risk. With the Cisco UCS 82598KR-CI adapters, a maximum of two adapters are presented to the VMware ESX hypervisor running on the blade. This interface count does not support a fabric failover, and the service console must be migrated to the Cisco Nexus 1000V Series Switch along with all these other adapter types if any high-availability requirement exists. The actual migration of this interface during VMware ESX deployment on the blade is discussed in the specific adapter section later in this document, but for more detailed information about how to migrate a user's service console, see the Cisco Nexus 1000V Series documentation. Even though Green IT has become a hot topic in 2010, its roots run back to early 90's. In 1992, the Energy Star program was launched by the U.S. Environmental Protection Agency. This program encouraged new electronic devices to be more energy-efficient by lowering energy consumption, efficient design and reduced use of hazardous material. The Energy Star program was revised in 2006 and now includes much stricter efficiency requirements and a tiered ranking system for approval. High availability is a system design protocol and associated implementation that ensures a certain degree of operational continuity during a given measurement period. 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. |
