  4. 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. 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. 6. Virtual Server Concept 5/21/2018 6 • One host typically house many virtual servers (virtual machines or VMs).

  7. 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.

Server Virtualization Technologies 5/21/2018 9 Features KVM VMware Microsoft Hyper-V Xen Server Proxmox VE High availability   Requires Microsoft Failover clustering, limited guest OS support   Flexible authentication      Single-view for Management (centralized control)  Yes, but requires dedicated management server (or VM) Yes, but requires dedicated management server (or VM)   Virtual machine live migration      Resource control      Disk encryption      Bare metal type 1 hypervisor     
  10. 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 .

  28. 28. Experiment Data 5/21/2018 28 USER DEMAND Users : 1500 Memory : 2 GB/VD Space : 60 GB/VD Processor : 1 Vcpu/VD REQUIREMENT Memory : 3000 GB Space : 90 TB
  29. 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. 30. Power Savings 5/21/2018 30 You can significantly reduce your power cost by using virtual environment. How ?
  31. 31. Power Comparison 5/21/2018 31
  32. 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. 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.
