Dear Experts<br />
Servers having two PDU's and each power units connected to separate UPS if one UPS goes down server hardware will continue to work with other UPS, have following doubts<br />
Does server hardware consumes power from both the PDU’s all the time equally OR &nbsp;is there a concept that one PDU will be primary and if this goes down only then secondary PDU becomes active and this will keep the server running. please help me understand. Thanks in advance.

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

IT Administration is the processes and best practices for programming and development, and incorporates methodologies for managing activities and projects. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, extreme programming and various types of agile methodology. The life-cycle "model" is a more general term for a category of methodologies, and a software development "process" a more specific term to refer to a specific process chosen by a specific organization.

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
