Hi,
since my 2-bay synology NAS got a little small, I decided to build myself a FreeNAS-based NAS. Unfortunately, so far I am not impressed. I got two rather large problems and a smaller one.
The NAS:
Mainboard: Asrock AM1H-ITX
4x2TB WD HDD (2x RED, 2x GREEN)
CPU: AMD Athlon 5150
8 GB DDR3 RAM
IN WIN Thin Mini-ITX 120 Watt PSU
Problems:
1. powerd does not work. As soon as I enable it, the entire system turns instable, usually just rebooting after one or two hours. Consequently the CPU just runs at 1,6 GHz with it's highest voltage setting all day long, which is really not necessary. There doesn't seem to be a version of k10ctl for FreeBSD for me to set the frequency and voltage manually. The bios has no so option.
2. The drives do not spin down automatically -- the necessary flags are set to 5 minutes. I can however send them to standby manually by invoking "ataidle -S 5 /dev/ada0" but once they are reactivated this does not work anymore. While idle power draw with drives active is at 32 Watts, it drops to 22 Watts when the drives spin down. This is quite a nice drop, which I would really want to have.
3. Transfer rates using Windows and SMB are good (~100 MB per second). However, using Linux and SMB this drops to ~35MB/s. While I can see this being a problem of the Linux+SMB combination, I do not understand why m ysftp transfers are also limited to ~35MB/s when using Linux.
Any suggestions?
Thanks
Pat
