Dual core Atom based home server

Here we go, the small box based on Dual Core Atom 330 with total consumption around 50W replacing a 150W old Pentium 4 tower. It used to be around 35C in my wardrobe, now we are back to silent operation and normal room temperature. As I mentioned before, I have there 1TB 3.5” drive mostly idle 95% of the time and 500GB 2.5” laptop hard drive for 24*7 torrents.
And I am using W7 x64 build 7100 (RC) with it. I tried Home Server 2008 R2, Ubuntu 904, FreeNAS. I believe that W7 beta is so far the best value proposition, as it is very stable, versatile and free till the June, 2010.

My new home server build on DualCore Atom

I am in that sweet time phase, when I made my research and ordered the parts. ETA is on Monday. I am building my home server on
Modecom mini ITX case with external power adaptor (96w, $70)
DualCore Intel Atom 330 in Intel D945GCLF2 (90$) – which has 1 IDE, 2 SATA connectors, Gigabit NIC
2GB RAM ($25)
500GB 2.5” laptop hard drive ($100)
and I will reuse my 1TB Barracuda 3.5” SATA from my old server.
Going for a laptop hard drive was a tough decision. I had to consider that laptop drives have limited capacity, that they are 2 more expensive than 3.5” drives, and the fact that 2*3.5 drives do not fit into mini ITX case (at least the cases that I could find in Latvia) because most of MINI-ITX cases support only one 3.5” drive and a slim CD/DVD. An alternative was to go with micro-ATX case, but then I would have to deal with the problem of finding the low-power PSU, which are not available in Latvia at all. Buying those online is possible from mini-box.com or minipc.de, but it costs an arm and a leg (upward of $100), negating any savings on purchasing a larger hard drive.
Moreover, I had to give up any idea of toying with the RAID for data protection. I will backup my personal data, which includes about 30GB of documents, photos and music, between server and my gaming pc hard drive, but for the movies, there will be no backup in this setup. I think that movies are not a critical information, because you can restore most of them from internet. At the same time, I am happy with the setup, because my space requirements will be met for another year. (I managed to fill about 700GB during 1 year). Only the small drive will be running 24x7 for torrents. It consumes less energy than larger drive and make less noise too. By the way, noise was not a consideration in this build, since I have a separate technical room for my computers. If I had to build a completely calm pc (for use on the table or in a living room) I’d had to take more expensive fanless MSI board with SSD drive, which cost too much to my taste anyway.
As for OS, I will be choosing between WHS and FreeNAS. I have seen FreeNAS, and I have yet to try WHS for the first time. And of course, there always is W7 and Ubuntu, but I do not see a benefits to running those on a headless server.

Using Asus eeepc 1000h as home server

I want to replace my P4 2.8GHz home server (Power draw around 100+ W/h, no processor scaling) with something more efficient. The current king of the hill in terms of power efficiency while providing adequate performance seems to be Intel Atom processor. I already have a netbook based on single core Atom, and before jumping and taking a mini ITX motherboard based on Atom (good list here at kramfs.com) I decided to test how well it is doing its job in the netbook.
So, I connected eee 1000h to my router via ethernet cable. Unfortunately, 1000h has only 100Mbps NIC. I shared a movie folder with the network, and connected 4 computers, playing 2 HD videos (up to 2.5 MB/s each) and 2 DVD videos (up to 1MB/sec each).
On the picture – eee pc 1000h as server. 2 laptops and home entertainment PC, and old server (not visible) are playing videos, trying the limits of eeepc. Didn’t succeed by the way. Here are proof pix.
Network utilization seems low, peaking only at some 43% (or 6MB/sec). I used a 9GB movie for this test. Sure it would be different if I used a 20GB movie. But it also reflects the current state of torrent popularity in our country. Videos larger than 10GB are not here yet. I watched “The Matrix” in 20GB hi-def, but deleted it later.
CPU usage averaged around 15-20% in the process. So, for my current usage patterns, it means that all my kids can watch their own movies on as many computers as I got in this house.
I am now on the crossroads, my two options are
1) take a new mobo based on DualCore Atom. It is around $100 here, and only $20 more expensive than single core Atom option. But it has Gigabit NIC, which is good for file transfers. Investment - 100$ mobo, $70 case with power supply, $30 2GB RAM stick. Total $200. The drawback here – I get another computer to care about.
2) use my 1000h as home server, as I do not have much use for it since I got a 12inch work laptop. I would need to buy a 500GB 2.5” SATA HD to make this a useful home server. My current server has 1TB 3.5” SATA and I could move it into my video/game machine. Investment - $120 for harddrive. Drawback – slow file copying on the network. Copying one file immediately fills the NIC with some 11 MB/sec transfer. My current transfer speeds are limited by harddrive writing speeds at 35-40MB/sec.
Decisions, decisions…
