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. Use server-based energy management software tools to run workloads in the most energy-efficient way. This may include taking advantage of lower energy tariffs at different times. Operating a Data Center not only requires a comprehensive skill set, but also a little forethought into the overall industry landscape. 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. For all of the upside virtualization is not magic, and it can introduce some new challenges. But in most cases the many cost and efficiency advantages will outweigh any issues, and virtualization will continue to grow gain popularity. 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. The Cisco Unified Computing System streamlines data center resources to reduce total cost of ownership, scales service delivery to increase business agility, and radically reduces the number of devices requiring setup, management, power, cooling, and cabling. A green data center is a repository for the storage, management, and dissemination of data in which the mechanical, lighting, electrical and computer systems are designed for maximum energy efficiency and minimum environmental impact. According to one aspect of the invention, a data storage system includes a disk drive array including a plurality of disk drives; a first storage processor for controlling the operation of the data storage system; a second storage processor forcontrolling the operation of the data storage system; a first arbiter for controlling communication of data from the first storage processor and the second storage processor to a first group of disk drives of the disk drive array; and a second arbiterfor controlling communication of data from the first storage processor and the second storage processor to a second group of disk drives of the disk drive array. Selected data is redundantly stored on disk drives in the first group of disk drives andthe second group of disk drives, such that, upon failure of the first arbiter, the selected data is available to the first storage processor and the second storage processor through the second arbiter. A broad group of industry-leading partners supports the open, standards-based unified fabric architecture of the Cisco Nexus 5010 Switch. This switch also delivers more than 500 Gbps of switching capacity with 20 fixed wirespeed 10 Gigabit Ethernet ports that support Data Center Ethernet and FCoE. In addition, one expansion port supports 8-port 1/2/4 Gigabit Fibre Channel, 4-port 10 Gigabit Ethernet (Data Center Ethernet and FCoE) and 4-port 1/2/4 Gigabit Fibre Channel, and 6-port 10 Gigabit Ethernet (Data Center Ethernet and FCoE). |
