Featured Solution: Cisco Unified CommunicationsQ. What is a data center? A. A data center is a computer facility designed for continuous use by several users, and well equipped with hardware, software, peripherals, power conditioning and backup, communication equipment, security systems, etc. Approximately half of the power consumed by a data center is required for cooling. As heat load increases, more floor space must be reserved for cooling equipment. Without high ceilings (20 feet or more), the hot exhaust air of servers is likely to become in-take air for servers mounted in the upper portion of a cabinet. Hardware assets should be used well after their depreciated financial life has ended — for as long as is technically possible. Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. Virtual machines offer many benefits: server consolidation, increased utilization and faster recovery times after failure. Ini a virtualized network, each virtual machine can interact independently with other devices, applications, data and users as though it were a separate physical resource. The ideal storage management solution should back up files and information automatically and in real time. In addition, organisations need a storage management and data protection solution that enables them to cope with rapidly increasing storage volumes and the increased complexity of desktop and laptop computers. With the Cisco UCS M81KR adapter, multiple virtual interfaces (VIFs) can be identified to match those used by the service console, VMware VMkernel, virtual machine data, Cisco Nexus 1000V Series VLANs, etc. as required. Each of these adapters can be defined within the Cisco Unified Computing System as connected to an individual fabric interconnect and, optionally, enabling a failover to the other. Green IT facilities offer employees a healthy, comfortable work environment. In addition, green facilities enhance relations with local communities. Data storage systems are used in a variety of businesses for the purpose of storing and maintaining data which is critical to the operation of the businesses and their customers. It is very important that such data storage systems be highlyreliable to minimize or eliminate the chance of losing data if the system fails. The most secure and reliable systems employ total redundancy, in which every component of the system is replicated, such that, upon a failure of a component, anothercomponent takes over operation, so that the data storage system can remain fully functional. For example, two storage processors may be provided in a system such that if one fails, the other assumes the operation of the failed processor as well asmaintaining its own. However, total redundancy is expensive and can be an inefficient use of system resources. 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. |
