- 4. Objectives 5/21/2018 4 • To reduce hardware cost. • To ensure reducing downtime. • Easier to maintain virtual PC’s in one server. • Hardware resource utilization using advanced virtual environment with virtual networking. • To select, install and setup open source virtualization and operating system virtualization on commodity hardware.
- 5. Traditional Server Concept 5/21/2018 5 • Servers are often referred to by their function i.e. the Exchange server, the SQL server, the File server etc. • If the File server fills up or the Exchange server becomes overtaxed, then the System Administrators must add in a new server. • Unless there are multiple servers, if a service experiences a hardware failure, then the service is down.
- 6. Virtual Server Concept 5/21/2018 6 • One host typically house many virtual servers (virtual machines or VMs).

- 7. Virtual Server Concept 5/21/2018 7 • A virtual server can be serviced by one or more hosts e.g. storage, services etc. • Virtual servers can still be referred by their functions i.e. email server, database server etc. • If the environment is built correctly, virtual servers will not be affected by the loss of a host. • Hosts may be removed and introduced to accommodate maintenance.

- 10. Citrix Xen is a free hypervisor, high performance clouds. Monitors average CPU and memory utilization across all active hosts in the pool Monitors change in a pool and shared storage configuration. Monitors VM migrations. Easily configure Xen desktop and Xen app virtualization. Reason For Choose Citrix Xen 5/21/2018 10 .

- 29. Server Specs 5/21/2018 29 For 1500 users we need five High end server host and can use storage. Server Example: HP ProLiant DL380p Gen8 Server Storage Example: EMC
- 30. Power Savings 5/21/2018 30 You can significantly reduce your power cost by using virtual environment. How ?
- 32. Future work 5/21/2018 32 Virtualized desktop environment will be increased. Also deploying server virtualization, network virtualization, storage virtualization and application virtualization. Data security issues will be fixed easily by storing the data on the virtual servers.
- 33. Conclusion 5/21/2018 33 To sum up, virtualization has many benefits to provide engineering. It is a form of abstraction used to simplify the use of a computer's resources. Through this abstraction, resources become represented into simpler or different forms. The benefits of using virtualization include portability, security, performance and reliability. Productivity of the organization will be increased.
