Hi, I've had an R210 recently to set up for a client and thought I'd share the power consumption figures that I recorded with the list.
Basically, very impressive results IMO, when you consider the last R200 (X3220) which I set up used 135-odd watts idle... Disks: 2x 250G Seagate ES.3 SATA 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 With 100% CPU usage (on all 4 cores),and having issued an "ipmitool mc reset cold" command, whilst spinning-up both hard disks having previously put them to sleep with "hdparm -Y": 0.56 amps / 131 watts I could probably get the CPU/mem power usage up a little bit higher, as my CPU loading was a bit simplistic (burnBX + memtester). The CPU frequency scaling module doesn't seem to load. This is either because Dell's BIOS doesn't support it, or it Dell's BIOS cpu frequency interface doesn't work with the Debian Lenny kernel. More to follow... Cheers, Tim. -- South East Open Source Solutions Limited Registered in England and Wales with company number 06134732.
