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. Power continues to lead as a concern for data center operations. Data centers are designed to a specific power density - watts per square foot - with a typical cabinet of equipment occupying 14 sq. ft. of space. Where possible, use outside free air as an alternative to expensive air conditioning. Recent changes to the Federal Rules of Civil Procedure put IT on the front lines for ensuring a business is complying with regulations, notably Sarbanes-Oxley and HIPAA. Not only is it necessary to store key data for longer periods, but being able to retrieve information at a granular level –right down to specific emails –is now an IT responsibility, one that if not handled properly could result in a vacation with the local municipal system. The usual goal of virtualization is to centralize administrative tasks while improving scalability and work loads. Virtualization was first introduced in the 1960s by IBM to boost utilization of large, expensive mainframe systems by partitioning them into logical, separate virtual machines that could run multiple applications and processes at the same time. In the 1980s and 1990s, this centrally shared mainframe model gave way to a distributed, client-server computing model, in which many low-cost x86 servers and desktops independently run specific applications. Most storage management and backup software products lack the critical features required for the complete protection of all information stored on these machines. Specifically, users need comprehensive recovery tools to help them easily find and restore lost data and quickly bring idle computers back to full operation. The Cisco UCS uses three adapter types, with four specific models: the Cisco UCS 82598KR-CI 10 Gigabit Ethernet Adapter, UCS M71KR-Q QLogic Converged Network Adapter, UCS M71KR-E Emulex Converged Network Adapter, and UCS M81KR Virtual Interface Card. Each of these cards has a pair of 10 Gigabit Ethernet connections to the Cisco Unified Computing System backplane that support the IEEE 802.1 Data Center Bridging function (formerly called Cisco Data Center Ethernet) to facilitate I/O unification within these adapters. On each adapter type, one of these backplane ports is connected through 10GBASE-KR to the A-side I/O module; then that connection goes to the A-side fabric interconnect. 10GBASE-KR is a copper midplane technology for interfacing adapters and switching elements through these midplanes. The other connection is 10GBASE-KR to the B-side I/O module; that connection then goes to the B-side fabric interconnect. Figure 3 later in this document shows this connectivity. 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. 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 Nexus 1000V switch is a software switch on a server that delivers Cisco VN-Link services to virtual machines hosted on that server. It takes advantage of the VMware vSphere framework to offer tight integration between server and network environments and help ensure consistent, policy-based network capabilities to all servers in your data center. |
