The Project objects
• Power saving server environment
• Server resource utilization
Virtual Server
• d
Virtual Networking implementation
• Select a virtualization platform - In no particular order, Microsoft, XenSource(Citrix), VMWare are among the most popular choices.
• Microsoft’s Hyper-V
• VMWare
• XenSource(Citrix)
• Xen (Open Source)
• Guest system– fully virtualized
para virtualized» OS : Linux, Plan9, OpenSolaris» hypervisor:Xen,Virtuozzo,Vserver,OpenVZ
• hybridkernel-based virtual machine
• Cloud server
Electricity power calculation
• A fluorescent light power consumption
30 – 40 W
Electricity power calculation
• General desktop/server’s power consumption
• CPU : 100W• RAM : 8W• Graphic card : 30W• Mother board : 20W• CD-ROM : 20W• HDD : 13W• Monitor : 40W
-------------------------------------------------------------------
Total = 230W
Electricity power calculation
• General server power consumption
(per day)
230W x 24(hours) = 5,520 Wh
= 5.5 KWh
5.5kWh $ ?

Virtual Server Advantages
• Power saving over multiple physical servers
• Simplify system administration by integrating all servers into one physical machine
• Server hardware resource optimization
Virtual Server disadvantages
• When host server machine crash, all virtual servers embedded in the server crash too.
• Key areas of benefit of server virtualization:• Resource utilisation is increased • Cost of ownership is dramatically reduced• Management is simplified and burden reduced• Availability is increased.• Deployment and development timescales and
reduced dramatically• Return on investment is increased
