Virtualization - Call PBM IT Solutions at (888) 233-6471A data center is where the majority of an enterprise servers and storage are located, operated and managed. Per-rack power requirements constrain the number of racks a data center can support. A typical 10,000 - 20,000 sq. ft. facility designed for 50 - 100 watts/sq. ft requires 1/2 megawatt to 2 megawatts of power. Availability and cost of utility power in the megawatt range is expensive and difficult to obtain. Supporting infrastructure - generators, ATS, UPS, and distribution equipment - also are costly. Careful planning and growth projections must be maintained to ensure power requirements can be met. Develop a dashboard of data center energy-efficient metrics that provide appropriate data to different levels of IT and financial management. Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. The idea is that virtualization disguises the true complexity of the network by separating it into manageable parts, much like your partitioned hard drive makes it easier to manage your files. 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. 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. The Cisco Unified Computing System enables more dynamic and agile data centers, in which server identity (MAC addresses, worldwide names [WWNs], firmware and BIOS revisions, network and storage connectivity profiles and policies, etc.) can be dynamically provisioned or migrated to any physical server within the system. There is growing pressure from environmentalists and, increasingly, the general public for governments to offer green incentives: monetary support for the creation and maintenance of ecologically responsible technologies. An effective High Availability (HA) data solution must address both unplanned and planned causes of downtime to achieve a truly fault tolerant and resilient IT infrastructure. Unplanned downtime is primarily the result of computer failures, data failures and human error. Planned downtime is primarily due to data changes or system changes that must be applied to the production system. The Cisco Nexus 5010 Switch foundation is built upon High-performance 10 Gigabit Ethernet, Data Center Ethernet, Fibre Channel over Ethernet (FCoE), and Virtual-machine-optimized networking. |
