Hi,
as the title says, I am about to reduce the overall power consumption of my server rack and its components.
Among other devices I run a Supermicro X9DRi-LNF+ mainboard with 2x e5-2660v2 with 128GB DDR3 ECC.
Basically that's too much power for my homelab but I got this set some time ago on ebay for a decent price. That time power was not my concern.
Currently the system runs ESXI7 with 7 VMs active and it idles at around 5% CPU load with peaks to 20%. I also use some VM with Desktop OS'es which I switch on from time to time. Saying this, means I need some CPU headroom but the system idles most of the times. When idle, the system draws 110W from the wall.
Since I am trying to reduce my power bill I thought about replacing it with a single core cpu and mainboard. Since DDR4 ECC Ram is extremely expensive, I'd rather stay with the DDR3 Ram I have. However, by doing so, my options are limited.
I broke it down to a couple of CPUs which sell cheap on ebay and could potentially reduce the power draw.
E5-2695 v2 - 12C - 115W TDP -> powerful CPU but still high TDP
E5-2648L v2 - 10C - 70W TDP -> looks quite promising to me - not sure tough if it has enough power.
E5-2650L v2 - 10C - 70W TDP
E5-2450L v2 - 10C - 60W TDP
E5-2448L v2 - 10C - 70W TDP
In terms of mainboard I'd probably go for a supermicro X9 mainboard depending on the cpu socket
Do you guys think, that way make sense in terms of reducing my power consumption? It actually should reduce the consumption by 40W at least which equals to roughly 100€/y for the power bill.
Does moving from a dual cpu to a single cpu actually make a big difference? especially when idling?
any other thoughts on my idea?
thx & Best
