Q. 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. Data Centers are needed to protect against data loss. Statistics about the harm done to businesses by data loss in a disaster, suggest that nearly 50 percent of companies report each hour of downtime could cost up to $50K. Beyond backup and recovery protection, ensuring maximum data center availability and up time is clearly crucial to business success. IT executives will have to make sure the data can be audited and meet regulatory and compliance rules as well as make sure the growing storage demands don't break the bank. In-house data centers can be a business weak link if proper attention isn’t paid to power use, cooling capacity, disaster recovery preparedness, running IT to support compliance initiatives, and staffing flexibility to support utility computing initiatives. Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console. Storage virtualization is commonly used in storage area networks (SANs). Hypervisor software is the secret sauce that makes virtualization possible. This software, also known as a virtualization manager, sits between the hardware and the operating system, and decouples the operating system and applications from the hardware. The hypervisor assigns the amount of access that the operating systems and applications have with the processor and other hardware resources, such as memory and disk input/output. Many IT departments encourage users to save critical data to available network servers under the control of enterprise software. This policy, in most cases, is not successful, since users store data locally, especially mobile users who are seldom connected to a network. 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. The recent attention on Green IT technologies has opened new career opportunities for IT professionals. Since some of the areas need specialized attention such as energy efficiency, environmental laws and ethical disposal, some organizations have created new positions and divisions to embrace this upcoming trend. 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. 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. |
