Hello
I am seeking for an affordable (about ~150$ Mobo+CPU) solution to get a mini-ITX, low-power NAS that supports ZFS with fully encrypted files (BSD GELI or ZFS-native encryption as currently seen in Solaris11 Express) and serves those via SMB to windows clients.
I want to get a Gigabit-Ethernet connection nearly/full saturated, so I am aiming towards ~100 MB/sec throughput (3x2TB RAIDZ for a start)
I have already started multiple threads on specific topics:
- Atom D525, dual-core with HT/SMT, so 4 logical cores: http://hardforum.com/showthread.php?t=1584334
- Athlon x2/x3, dual/triple cores: http://hardforum.com//showthread.php?t=1584892
sub.mesa recommended to take a view at the new AMD Fusion/Zacate Platform, specifically the AMD E-350, which beats the Atom D525 in every aspect.
As I am interested in encrypting the filesystem the finest solution would be an Intel i5 CPU since it supports AESNI. AESNI-instructions are supported by bsd's geom framework and therefore enable pretty fast encryption. Using the i5 costs about 250-300 (mobo+cpu).. .
power-efficiency wise the i5-solution is pretty good since it combines CPU and GPU with a TDP of ~70W (only at full load and if GPU stressed too!).
Idle-power is also very good on these cpus. So overall the i5 seems to be a winner, only it's somewhat expensive and, I think, somewhat overkill for a mini/cheapo NAS.
While reading about the AMD E-350, the new Via Nano x2 was listed in the following benchmarks: http://www.anandtech.com/show/4134/the-brazos-review-amds-e350-supplants-ion-for-miniitx/8
That CPU is Via's first and newest dual-core and among VT-support it provides VIA padlock. Padlock are encryption-supporting instructions (just like AESNI). And best of all, padlock seems to be supported by FreeBSD GEOM/GELI (padlock_load="YES" in loader.conf)
So it seems I'll try to get some more information about that Nano x2. In the meantime, any comments on the feasibility and further advice are very much appreciated.
