An OpenSolaris EeePC Homeserver

Early last year I was one of the first to get an original Asus EeePC 4G 701, to be used as an OpenSolaris based mobile presentation and email machine. Well - almost two years later, counting the number of occasions I actually used the machine for that purpose, I decided to convert the EeePC into an intelligent ZFS Storage controller for my home data. So what are my requirements? Actually not that many:
  • 500GB of ZFS secured data, shared via SMB (today) or streamed via DLNA (later), using a 100MBit network
  • Low power consumption
So on to genunix.org I went and downloaded the latest OpenSolaris build as USB memory stick image. But to my surprise, installation was not possible. OpenSolaris seems to have grown some fat since 2009.06 days, too fat to fit onto the 4GB internal SSD disk. Just before giving up I recalled the website of that EeePC wizard over in Japan, who helped me getting OpenSolaris onto the EeePC in the first place, and I found images customized and pre-compressed for the EeePC. Thanks, Masafumi!

After getting OpenSolaris up and running I went hunting for a USB disk solution able to house two 2.5" drives in one case but without a RAID controller. ZFS is happy with Just A Bunch Of Disks. The IcyBox IB-2221StU-B was the perfect fit. With just 130 Euros additional investment I converted my EeePC to a storage server with 500GB mirrored capacity.



Setting up the data pool, and sharing the file systems was a breeze with help of various available HowTos. Transfer speed to the ZFS mirror is 8-10MByte/sec, which is close to the limit of the 100MBit network, leaving the EeePC's tiny little 630MHz Celeron 50% idle (no dedup or compression so far).

So what about the power consumption? Low enough to be ready for 24/7 operation? Equipped with a high-definition power-meter able to measure with one watt accuracy, I got these values:
  • EeePC, normal operation: 15.7 watts (almost 4 watts already wasted by the power supply...)
  • EeePC, closed lid: 13.4 watts
  • EeePC, closed lid, plus IcyBox with to 500GB 2.5" disks and poer supply: 17.8 watts
  • Above configuration during "zfs scrub": 21 watts
So my OpenSolaris EeePC Homeserver draws between 17-21 watts which translates to 3 euros a month or 8kg CO2 a month, or three liters of gasoline.

ZFS rettet die Welt

Endlich ist es soweit. Die erste Folge von CSI:Computer Systems Integration (formerly known as Solution Center Live) ist online! In dieser Folge zeigen wir, wie man mit einem Laptop, Solaris 10, ZFS und ein paar USB-Sticks einen Storage Server X4500 für den Hausgebrauch bauen kann:


Wer es selber nachbauen möchte: Der Chefermittler persönlich schreibt über die technischen Hintergründe in seinem Blog.

Viel Spaß!
