NEW Power Consumption of the Dell C6100

[uberguru]

I just read this article about the power consumption of the Dell C6100 Dell PowerEdge C6100 review | 3 | IT PRO

In idle we saw one, two, three and four nodes draw a total of 136W, 205W, 275W and 348W. Under pressure these figures rose to 295W, 516W, 737W and 964W respectively. An average peak of 241W per node under heavy load is low, showing just how power frugal the C6100 is.

So basically the 4 nodes can max out to 962 watts...that is 8 amp(120 volt) or 4 amp(230 volt)

The Dell C6220 on the other hand Dell PowerEdge C6220 review | 2 | IT PRO

To test power consumption, we hooked the C6220 up to our inline power meter. With each node loaded with Windows Server 2008 R2 and idling along we saw first, second, third and fourth nodes draw a total of 135W, 200W, 290W and 350W, respectively.

Using the Sisoft Sandra benchmarking app to push the CPUs to maximum load on each node we saw power peak at 364W, 671W, 945W and 1242W. Dell estimates the C6220 will save you around 100W of power over four servers.

Not really sure what the question is here? The review C6100 has 8x 95w TDP processors, full RAM slots, and 2x SATA drives per node. I did not see mention ambient temperatures for the test. The C6100 fans spinning faster due to the hot CPUs, drives memory and a hot room may also vary with temperature.

The Dell C6220 was a design improvement as they moved to the LGA2011 platform (there is a video embedded in the first post of the main thread on this here.) It can take more power hungry processors for example. Also interesting in that article is "All cooling is handled by four fans behind the disk backplane but these are not hot-swappable and don’t have integral power connectors." I believe that was one of the big changes in the C6220 that the fans were made hot swap. Maybe they didn't open up the case?

Also, they just said power meter. At these load levels that can be decently important.

My C6100 with eight L5520 CPUs, 38 8GB DIMMS, six 3.5" 7200 RPM drives and six SSD drives draws ~385 watts as a Hyper-V cluster with all VMs running but not doing that much - just background processes and a bit of VM replication. I have all four nodes set to "high performance" mode in the BIOS.

Looking at the power usage is useless without factoring in the performance increase.

I see i didn't even know they used 95W CPUs. Also you are right...the temperature under testing is very important because of the power draw from the fans.

Ok getting some faith in this thing now...wasn't believing the low power hype before..but i thinks its real..thanks for the info
