Q. Is power better in a data center? A. Yes. Energy is another important issue for every data center to review. In a data center, power is closely managed and monitored. Often multiple power grid connections and redundant power wiring is used to ensure high availability of power to network resources such as servers, routers, and switches. 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. IT executives will have to make sure the data can be audited and meet regulatory and compliance rules as well as make sure the growing storage demands don't break the bank. The rise in technology and a changing corporate landscape have presented data center operators new challenges. Virtual machines offer many benefits: server consolidation, increased utilization and faster recovery times after failure. Network virtualization splits available bandwidth in a network into independent channels that can be assigned to specific servers or devices. In many businesses, critical data is stored on desktop and laptop computers outside the reach of most enterprise storage management software products. This data is at significant risk. 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 starts with manufacturers producing environmentally friendly products and encouraging IT departments to consider more friendly options like virtualization, power management and proper recycling habits. According to one aspect of the invention, 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; and a second arbiterfor controlling 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. Selected data is redundantly stored on disk drives in the first group of disk drives andthe second 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 arbiter. 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. |
