  • Data Centre Structure 2
  • Major Data Centre Tasks  Infrastructure   Administration   Maintenance of services Training     Continue expansion Training the trainers Staff training Student training External cooperation 3
  • Data Centre Infrastructure    Data Center for Administration, Management, and Technical support. Backbone Networks (Access Network) In Main Campus. Remote Network to connect campuses. Network Service • • Provide service environment for O&M on Network and IT resources. Provide technical support to users from different campuses. • • Education Center : Provide education & training facilities for Users Provide the communication network and Telecommunication System • Connection of Remote Node (campus) with necessary core Optic fiber cables install LAN to utilize applications at the Organization level. • Remote Network • • Backbone Network (OSP) Data Center : Accommodate server farm & Application Hosting Area. • IT Center Provide central network services for all user of the network. Central Node at the main Office (Campus) • Access/Remote Node (Campus) : District Office, Police Office, Real Estate Registration Office, Vehicle Registration Office, Motorcycle Registration office • Other Organization : Royal Palace, National Assembly, International Airport, etc. 4

  • Virtualization 11
  • Virtualization  Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute.  Today’s powerful x86 computer hardware was originally designed to run only a single operating system and a single application, but virtualization breaks that bond, making it possible to run multiple operating systems and multiple applications on the same computer at the same time, increasing the utilization and flexibility of hardware. 12
  • How Virtualization works?  Virtualization lets you transform hardware into software. Use software such as VMware to transform or “virtualize” the hardware resources of an x86-based computer—including the CPU, RAM, hard disk and network controller—to create a fully functional virtual machine that can run its own operating system and applications just like a “real” computer. 13
  • How Virtualization works?  Multiple virtual machines share hardware resources without interfering with each other so that you can safely run several operating systems and applications at the same time on a single computer. 14
  • What is a Virtual Machine?    A virtual machine is a tightly isolated software container that can run its own operating systems and applications as if it were a physical computer. A virtual machine behaves exactly like a physical computer and contains it own virtual (ie, software-based) CPU, RAM hard disk and network interface card (NIC). An operating system or applications can’t tell the difference between a virtual machine and a physical machine. Even the virtual machine thinks it is a “real” computer. Nevertheless, a virtual machine is composed entirely of software and contains no hardware components whatsoever. 15
  • VMware approach  The VMware approach to virtualization inserts a thin layer of software directly on the computer hardware or on a host operating system. This software layer creates virtual machines and contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently so that multiple operating systems can run concurrently on a single physical computer without even knowing it. 16
  • Benefits Virtualization (1)    Virtualization essentially lets one computer do the job of multiple computers, by sharing the resources of a single computer across multiple environments. Virtual servers and virtual desktops let you host multiple operating systems and multiple applications locally and in remote locations, freeing you from physical and geographical limitations. In addition to energy savings and lower capital expenses due to more efficient use of your hardware resources, you get high availability of resources, better desktop management, increased security, and improved disaster recovery processes when you build a virtual infrastructure. 17
  • Benefits Virtualization (2)     Compatibility: Virtual machines are compatible with all standard x86 computers Isolation: Virtual machines are isolated from each other as if physically separated Encapsulation: Virtual machines encapsulate a complete computing environment Hardware independence: Virtual machines run independently of underlying hardware 18
  • Virtual Infrastructure  a virtual infrastructure is a dynamic mapping of physical resources to business needs. While a virtual machine represents the physical resources of a single computer, a virtual infrastructure represents the physical resources of the entire IT environment, aggregating x86 computers and their attached network and storage into a unified pool of IT resources. 19
  • Benefits of Virtual Infrastructure  By decoupling the entire software environment from its underlying hardware infrastructure, virtualization enables the aggregation of multiple servers, storage infrastructure and networks into shared pools of resources that can be delivered dynamically, securely and reliably to applications as needed. 20
  • Benefits of Virtual Infrastructure  This approach enables organizations to build a computing infrastructure or Data Centre with high levels of utilization, availability, automation and flexibility using building blocks of inexpensive industry-standard servers. 21
  • AppLogic Example: A Virtual Data Centre    AppLogic is a grid operating system which enables utility computing for running and scaling web applications. AppLogic captures and operates on the logical structure of the application. This makes it very easy to assemble, deploy, monitor, control applications visually in a browser. 22
