• 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

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

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
