What data center requirements involve the combined efforts of facilities and IT staff? Operating a data center at peak efficiency and reliability requires the combined efforts of facilities and IT staff. 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. Raise the temperature of the data center to around 24 degrees Celsius, while ensuring that all equipment is certified at the new temperature. This will reduce the level of cooling required and, thus, the energy bill. In-house data centers can be a business weak link if proper attention isn’t paid to power use, cooling capacity, disaster recovery preparedness, running IT to support compliance initiatives, and staffing flexibility to support utility computing initiatives. 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. Hypervisor software is the secret sauce that makes virtualization possible. This software, also known as a virtualization manager, sits between the hardware and the operating system, and decouples the operating system and applications from the hardware. The hypervisor assigns the amount of access that the operating systems and applications have with the processor and other hardware resources, such as memory and disk input/output. To qualify as a true enterprise solution, a storage management system must be able to scale across the entire enterprise. This means it must be able to handle multiple servers spread across wide geographical areas. The solution should further leverage technologies such as clustering and load balancing to support hundreds or even thousands of client computers. It also must support various network infrastructures and firewall configurations. 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. Even though Green IT has become a hot topic in 2010, its roots run back to early 90's. In 1992, the Energy Star program was launched by the U.S. Environmental Protection Agency. This program encouraged new electronic devices to be more energy-efficient by lowering energy consumption, efficient design and reduced use of hazardous material. The Energy Star program was revised in 2006 and now includes much stricter efficiency requirements and a tiered ranking system for approval. An High Availability Data solution must be practical to implement - minimizing acquisition cost and operational complexity while being able to efficiently scale-out to meet any performance requirement as business needs evolve. 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. |
