Hi,

I think about upgrading several servers from dual Nehalem L5640 (6C,12T,60W@2.26Ghz) to dual E5-2428L (6C,12T,60W@1.8GHz).

Performance is not a problem as original servers have load < 50%. What I concern about is the power consumption.

According to my measures dual L5640 consumes 150W without load and 250W fully loaded (for i in {1..64}; do yes > /dev/null & done).

Do you have any experience with power consumption of E5-2428L or similar (which means E5-2400 or E5-2600L)?

btw: The main reason I want to perform an upgrade is the fact, that Supermicro + Nehalem doesn't support IPv6 on IPMI. And as I want to move whole network to IPv6 network only, I have to unfortunately perform an upgrade.

I would skip that update. If you are going to swap CPUs, may as well get E5-2670's but moving to V3 would be a much more noticeable update. As you get more RAM slots and cores you can start consolidating a lot of those nodes.

My 2 systems
System A
Intel S2400 board , dual E5-2430L , 6x4gb ram , 1 Extra Intel ET nic , 3 SSD , 1 HD , WS12r2 idle at 51w

System B
Dual E5-2450L , S2400SC, 1 Intel 600gb SSD, 1 x WD 1TB HD, 1 x 640gb FusionIO duo SSD , I340-T2 NIC, 8 x 4gb ram
WS12R2 idle at 64w ,
FusionIO card consume around 10-15w by iteslf, so the system without FusionIO card idle around 50w

Edit: Add
4 x Ubuntu vms idling + hypver-v host idle @ 90w with FusionIO Duo SSD

SM E5-2630L single CPU , 8x4gb ram, 1 SSD , 1 extra Inte NIC card , 10gb NIC , ESXi6.0u2 idle @48w
SM E5-2630L single CPU , 8x8gb ram, 1 SSD , 1 extra Inte NIC card, 10gb NIC , 1 FusionIO 320gb SSD , ESXi6.0u2 idle @55w

SM is SuperMicro

You probably mean L5640, as L5630 is actually 4C 8T, 40W.
From a pure power consumption point of view, if you dont need the extra performance, you can downgrade.

Fixed, sorry for typo. It's been fixed. Why do you think that moving from L5640 to E5-2428L is a downgrade?

Ok guys, so I have upgraded 6-7 L5640 (and similar Nehalem servers) to E5-2428L and results are following:
  • I got support of IPv6 on IPMI :)
  • There is no support of IPv6 on PXE :(
  • Power consumption decreased by 50% (250W to 120W when fully utilized; 150W to 75W when idle)
  • Performance is almost the same (maybe slightly better, but I don't have any hard data - just feeling)
The result is that this upgrade was really good for the money I paid.

Not surprised, with the newer CPU's consider the TDP for max draw and cooling requirement scenarios but the power consumption on the newer generation gear is significantly better. Not only in CPU but everything is a couple years newer in manufacturing tech.

I've seen some similar issues between by E5645 (80w TDP) setup and my E5-2637 v (130w) system. Even though the E5 has a higher TDP, the system draws about 25% less power.

The major power saving from 1366 to the newer 2011 socket at idle comes mostly from the motherboard. A socket 1366 motherboard takes around 80 watts and runs hot.

Regardless of what CPU you use, upgrade from a 1366 to a socket 2011v1 gets you a saving of ~60+ watts at idle.

If your system is loaded with fans/HD/GPU cards then the percentage of power saving it not significant. The opposite is true.
