What is a data center? A. A data center is a place where business operate the part of their IT infrastructure that requires the highest grade of power, bandwidth, air conditioning, monitoring, and technical support. 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. Data center and IT managers must pay sufficient attention to the process of measuring, monitoring and modeling energy use in data centers. Operating a Data Center not only requires a comprehensive skill set, but also a little forethought into the overall industry landscape. 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 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. While you might think that the chances of having a major loss of data on your computer or even having your entire computer crash are very small, disasters happen and it is always best to prepare for the worst, especially when it comes to something as irreplaceable as your files. 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. Green IT can be defined as research in and use of IT in an efficient and environmentally friendly manner. High availability is a system design protocol and associated implementation that ensures a certain degree of operational continuity during a given measurement period. 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. |
