Featured Solution: Cisco High Availability DataEnergy is another important issue for every data center to review. Data center per-cabinet power consumption has steadily increased over the past several years as pedestal servers drawing 1KW/rack have given way to 1U/2U pizza box servers at 3.5KW/cabinet and blade implementations at 10KW/cabinet. Faster CPUs, larger memory chips, and smaller disk drives also continue to increase power demands. Where possible, use outside free air as an alternative to expensive air conditioning. Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. Virtual machines offer many benefits: server consolidation, increased utilization and faster recovery times after failure. Different virtual machines can run different operating systems and multiple applications while sharing the resources of a single physical computer. And, because each virtual machine is isolated from other virtualized machines, if one crashes, it does not affect the others. One of the primary reasons organisations do not perform frequent backups is that traditional storage management software runs over the network and can negatively impact network performance. As a result, many companies can only perform backups during off hours. However, this approach is also flawed because it exposes data to loss. A storage management solution that minimises network loading enables companies to perform backups as needed during the day. 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. 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. The data storage system may further include a third arbiter for controlling communication of data from the first storage processor and the second storage processor to a third group of disk drives of the disk drive array. Selected data isredundantly 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 thesecond 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. |
