Hi,
I need a 1u server consuming less than 0.4 Amps Power.

I asked about Server power consumption earlier
http://www.experts-exchange.com/Networking/Misc/Q_28100416.html

I will be using this server as a Email gateway and doesn't need lot of processing power.

I am looking for following configuration
1. Dual Core
2. 8 GB RAM
3. 4 SATA SSD drives at 250GB each
4. Network card at 100 MBPS

Can you suggest  any dell/Hp 1u servers?

Thanks

What equipment do you now have?
Virtualize a VM using VMware workstation, virtualbox to be your mail server

.4Amp is either 44Watthour or 88watthour.
Some "newer" systems that can be found on ebay, have power management bios settings.  Not sure the power requirement you mention is within a viable range.
Power consumption might be more if your mail traffic is significant.
Email gateway will presumably include anti-virus/malware/spam type of filtering capacity.


I think you set the target of power consumption significantly low.

Most often use 540-700 PS with the nominal average power consumption between 150-250watt 1.5-2amp in a 110v env or .75-1 amp in a 240v.

Hi,
I have been suggested by someone Dell r210 for less than 0.4 amp consumption. Is that right?

Thanks

RAM: 8G in 4 sticks (not sure if it was 1066, or 1333 DDR3)
CPU: L3426
Kernel: Debian 2.6.30-bpo.2-amd64
Supply voltage: 240
Ambient Temp: 20 degrees
Idle in Linux (no CPU freq scaling, HDs asleep): 0.19 amps / 33 watts
Idle in Linux (no CPU freq scaling): 0.2 amps / 40 watts
With 100% CPU usage (on all 4 cores): 0.38 amps / 82 watts
With 100% CPU usage (on all 4 cores), whilst doing a sequential read
from both hard disks with "hdparm -t": 0.38 amps / 81 watts
With 100% CPU usage (on all 4 cores),and having issued an "ipmitool mc
reset cold" command (to get the fans to full power), whilst doing a
sequential read from both hard disks with "hdparm -t": 0.46 amps / 114 watts

Concentrating on power consumption does not reflect the functions the server will be performing and the load it will be under.

Depending on what you have, virtualizing the multiple servers may reduce your overall power consumption.
