- 500GB of ZFS secured data, shared via SMB (today) or streamed via DLNA (later), using a 100MBit network
- Low power consumption
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
