Virtual Server Implementation Presented by HYUN
The Project objects • Power saving server environment • Server resource utilization
Virtual Server • d
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 $ ?
Electricity power calculation • A fluorescent light power consumption 30 – 40 W 230W / 35W ≒ 6.5 =
Power consumption comparison VS 5 Physical Virtual Server servers
Power consumption comparison 230W x 5 x 24h = 27.6kwh + a 230W x 24h = 5.5kwh + a
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.
Extra considerations for power saving • General SATA HDD 13W • NAND flash memory – SSD 1W
Extra considerations for power saving • External USB HDD 3W – 5W
Extra considerations for power saving • Power saving application • Turning off the monitor • Turning off the HDD • CPU power control etc.
