Welp, I’m a bit late to the party but will post just in case.
Setup details
- Asus WS C422 DC.
- Xeon W-2123(4c/8t).
- 4x Hynix 64G 2666 Reg ECC RAM.
- Montech century 550W gold.
- 3x 120-140 Fans.
- ASM1166.
- X520-DA2 10G.
- 2x Optane M10 16G as a boot pool.
- 3x 2-way mirrors of HC550 as data VDEVs.
- D5-P5530 & PM983 as sVDEV.
- Cheap no-name Chinese power meter.
Results
| Workload |  Consumption (W) |
|---|---|
| All drives connected, locked (pseudo-root of the) pool, network (2 DACs) connected. Pool unlock or pulling the DACs didn’t change consumption. | 95 |
| iperf3 9.9G | 118-120 |
| TimeMachine backup over Wi-Fi | 104-115 |
| Win backup (with built-in backup&restore). Hard (on compression) part with creating system image. CPU peaks are at 80-95% | 115-175 |
| ### Connected VGA and keyboard for the other tests | — |
| All drives (except boot) disconnected | 49 |
| X520-DA2 disconnected as well | 43-44 |
| ### CPU changed to Xeon W-2150B(10c/20t) | — |
| Only 2 RAM sticks left Back to 4 sticks |
42 44-46 |
| Removed ASM Removed keyboard Removed VGA |
42-44 41-43 41-42 |
| Shutted down Removed keyboard |
8.2 7.1 |
| Keyboard, VGA, ASM and X520-DA2 reconnected | 50-52 |
| All drives reconnected | 97-99 |
| TimeMachine backup over Wi-Fi | 103-119 |
| Win backup (same setup). CPU peaks are at 80-93% | 122-250 |
| iperf3 9.9G | 119-122 |
| fio on zstd-9 NVMe dataset | 254-258 |
Disclaimer: Backup values are not very useful, and I’m too lazy to properly measure average consumption.
Conclusion:
- Seems like the X10SDV-4C-TLN2F and Asus WS C422 DC have the same idle consumption.
- Taking into account that supermicro has better on-board network capabilities (IPMI, 10G), it should be considered more power efficient in the corresponding scenarios.
On the bright side, Asus has a much higher CPU upgrade limit (up to 18c/36t) and also a much higher RAM size limit (up to 1TB with W-22XX series). And a lot of PCIe.
