also, as mentioned before ... part of the server issue is server chip vendors are saying that over half of the server chips now ship directly to cloud operators that are building their own servers ... these quantities don't even show up in the server market numbers. cloud operators have been saying for some time that they build their own servers for 1/3rd the price from brand name server vendors. this possible is also behind recent news about IBM's attempts to unload its server business ... huge part of the market moving to the cloud as well was the downward pressure that cloud operators are putting on traditional server system prices and profits. part of the cloud server and mega-datacenter ecology is that they need to have significant idle capacity for on-demand online access (serving multiple timezones only partially offsets the peaks and valleys of online activity). the cloud operators have been behind server chip design where power drops to near zero when idle ... but able to come up to peak operation on-demand. the enormous improvement in server system price/performance also contributes to huge provisioning of idle capacity for on-demand online requirements. this is also big driver in the optimizing of other datacenter costs ... not only power costs dropping to zero for idle systems ... but also cooling ... and can come up to full operation nearly instantaneously. -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
