 for conferencing services. Wi-Fi A wireless service for branch and small offices that allows users to connect wirelessly to the router for Internet access. Session Initiation Protocol (SIP) SIP support permits trunking for Unified Communications (UC) functions such as presence and instant messaging with other sites and VoIP calls. Quality of Service (QoS) This prioritizes voice and video in the WAN. Voice and video are assigned tags that classify them with a higher priority than perhaps e-mail bits. These services are located on specialized circuit boards, or blades, within the router. Multiple services can be located on the same blade, which can have more than one processor. www.TechnicalPDF.com Blade servers hold blades that are arranged vertically and housed in racks in data centers. In contrast to horizontal circuit boards, vertical arrangements such as this conserve space and can share power supplies, fans, and cabling, thus consuming less energy. In addition, applications can be added or removed without taking the server out of service. Software to Monitor LAN-Connected Devices Small data centers with only one or two physical computers holding virtual computers are generally easier to manage than data centers with perhaps 20 applications installed on 20 physical servers. However, there is a learning curve for managing numerous physical servers, each running multiple operating systems and applications. It involves keeping track of which physical server each image resides on as well as the application's address. For large data centers, it is often easier to manage physical servers, where each one can be physically observed, than to manage an array of applications on virtual computers. However, in economic downturns, organizations are often reluctant to invest in software used to track LAN traffic and uptime. New applications critical to operating an organization's core operations have a priority in resource allocation.
