2. Defining IT Infrastructure • Includes hardware, software, and services • A set of physical devices and software applications that are required to operate the entire enterprise • Your firm is largely dependent on its infrastructure for delivering services to customers, employees, and suppliers. • You can think of infrastructure as digital plumbing, but its much more than that!

3. Levels of IT Infrastructure Three major levels of infrastructure: • Public • Enterprise • Business unit

6. Defining network components . Large internetworks can consist of the following three distinct components: • Campus networks, which consist of locally connected users in a building or group of buildings • Wide-area networks (WANs), which connect campuses together • Remote connections, which link branch offices and single users (mobile users and/or telecommuters) to a local campus or the Internet

7. NetworksDesigning Campus • A campus is a building or group of buildings all connected into one enterprise network that consists of many local area networks (LANs). • A campus is generally a portion of a company (or the whole company) constrained to a fixed geographic area.

8. Distinct characteristic of a campus environment • The company that owns the campus network usually owns the physical wires deployed in the campus. • Campus networks generally use LAN technologies, such as: • Ethernet, • Token Ring, • Fiber Distributed Data Interface (FDDI), • Fast Ethernet, • Gigabit Ethernet, • and Asynchronous Transfer Mode (ATM). • A large campus with groups of buildings can also use WAN technology to connect the buildings bandwidth is inexpensive because the company owns the wires

10. WANs • WANs connect campuses together. • When a local end station wants to communicate with a remote end station (an end station located at a different site), information must be sent over one or more WAN links. • Routers within enterprise internetworks represent the LAN/WAN junction points of an internetwork. These routers determine the most appropriate path through the internetwork for the required data streams. • WAN links are connected by switches, which are devices that relay information through the WAN and dictate the service provided by the WAN. • WAN communication is often called a service because the network provider often charges users for the services provided by the WAN (called tariffs).

11. WAN services are provided through the following three primary switching technologies: • Circuit switching • Packet switching • Cell switching combines some aspects of circuit and packet switching

14. Data Center Infrastructure • Data Centers are valuable resources as they get close to capacity those resources must be carefully managed • Infrastructure includes • Racks • Switches and switch ports • VLANs • Patch panels and cables (of all types) • Power utilization and monitoring • Generators • High voltage power components • HVAC components • By accurately tracking the usage of systems and their placement in the data center we can ensure that overload conditions do not occur BMS

15. Why? Data Center Infrastructure Optimization • Data centers cannot be self service when you near capacity • Finding available infrastructure is ‘not’ a trivial task • We need to get the most out of our “large $” investments in data centers • We need to protect the data center from overload or unbalanced situations

16. Where Are You? Where is your organization? Can best practices be learned from other IT environments? User/Role Specific Service Oriented Management Increased Operational Efficiency Less Total Cost of Ownership Measurement and Service Level Agreement Management Basic Standardized Rationalized Dynamic Recognition of Workloads Servers are generic Best Practices Generated and Consumed
