Power Monitoring
May 9 2008, 12:45 PM EDT I am sure you are well aware of the power restrictions in the datacentres of today. We are co-locating, as most medium business are, in a datacentre. We have 21 racks each of which are limited to 2KW. With the price of electricity increasing, we recently finished a 2 year contract during this time the cost of the racks increased from £4,500pa to £10,000pa, it is becoming increasinly important to insure that we are getting the best use out of our racks. We occasionally measure the power usage in our racks and most of the time we have underestimated the power and could probably save a rack, if we could organise the servers with the correct power usage. We were concidering installing power metering into our racks so that we could monitor the racks in real time. So the inclusion of power metering into the PowerEdge servers is a great plus for us. This got me thinking about ITA and whether it could do a job for us. Could ITA have a similar display to the Dell Datacentre Capacity Planner where you could locate your servers in the correct racks and correct “U”. While the DDCP does a pretty good job in reality it seems to over estimate (for obvious reasons) the power usage. My “vision” here would allow for the following:- • Get better estimates of mixing the measured servers with DDCP estimates for older servers, over-ride DDCP estimates with a “similar” model real measurements • Get real power usage, max power usage & time of max of a rack of servers • In ITA move a Server to a new rack to test its power usage before physically moving it. This will test that it doesn’t over power the rack. • Trend and alert on rack power usage. • You could even get really clever and create virtual racks with shortcuts to real servers to test layout before moving servers around. 3 out of 3 found this valuable. Do you? |
