Data Storage - Call PBM IT Solutions at (888) 233-6471Q. What is a data center? A. A data center is where the majority of an enterprise servers and storage are located, operated and managed. In a data center, servers, storage and network devices must be properly maintained and upgraded. This includes operating systems, security patches, applications and system resources such as memory, storage and CPUs. Hardware assets should be used well after their depreciated financial life has ended — for as long as is technically possible. Most line of business managers take for granted 100 percent IT up time, instant access to trained support personnel, uninterrupted access to data, and are dependent on top-flight management of IT assets in data centers. SMBs with an easy on-ramp to virtualizing their applications by automating the installation and configuration of hypervisor VMware. Businesses spend a lot of money powering unused server capacity. Virtualization reduces the number of physical servers, reducing the energy required to power and cool them. There are many ways that users can corrupt or lose information, including inadvertent file deletion, inadvertent file overwrites, new software installs, lost or stolen computers, hardware failures, virus or hacker attacks and natural disasters. 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. The Green IT approach can include several different phases in the lifecycle of a product – the development, production, usage and disposal of IT. Development must grant consideration to the environment; the production must take place using environmentally friendly production methods; the IT solutions must be used in an environmentally friendly manner; and finally, IT waste must be disposed of in an environmentally correct manner. All of these phases are supported by research and innovation in Green IT. 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; a second arbiter forcontrolling 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; and a third arbiter for controlling communication of data from the first storage processor andthe second storage processor to a third group of disk drives of the disk drive array. Selected data is redundantly stored on disk drives in the first group of disk drives, the second group of disk drives and the third 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 and third arbiters. 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. |
