From my first exposure to Slim Device’s original SliMP3 back in 2003 I was taken with the idea of streaming music throughout my house. The designers approach to this task I found very interesting. They literally give away an open source media streaming software intended for use on a file server. Then run their business by selling a dedicated hardware device to interface the music stream to a traditional stereo system.
The new HD for my SlimNAS box arrived last Friday. So the time to rebuild my SlimServer system is fast approaching. Right now it’s running on a 2.8 GHz Pentium 4, but since I’ve abandoned the idea of the Inguz on-the fly room correction in software it just doesn’t need all that CPU power. Nor does it need to be making all that heat & noise.
However, I don’t expect that the simplest solution will work. The T5700 has a 44 pin connector for the flash “disk-on-module” that it normally boots from. A reader in Denmark has indicated that he had some trouble getting the small HD to power-up when connected here.
One of my major mania’s is catching on. Josh Richards just blogged about trying Askozia on an H-P T5700 thin client. These are great little devices. I was so lucky to stumble into a source about 18 months ago. A major corporate concern was about to pay to have a few boxes of these little wonders “recycled” by Dell. A friend and I intervened and relieved them of that necessity.
At present I have three of these running in my home office.
Astlinux 0.48 in production
An Askozia testbed
FreeNAS with SlimNAS
With a 1 GHz CPU and 256 MB RAM (more if you upgrade the one SODIMM ) they are reasonably powerful, certainly enough for a small Astlinux or Askozia installation.
The third unit is perhaps most interesting. FreeNAS is a NAS software based upon FreeBSD and the m0n0wall framework. Like m0n0wall it’s simple, just enough to do what you need and not a lot more. It runs great on the T5700. However, a NAS needs storage, a lot of storage.
The T5700 has an internal IDE connector that’s fitted with a 256 MB flash disk-on-module (DOM). You could swap that our for a 2.5″ HD with the right sort of adapter, but laptop hard drives have high $/GB and less than ideal MTBF.
The T5700 also has a number USB ports but these are USB 1.1…less than ideal for interface to portable hard drives. I was able to find the optional expansion chasis on Ebay for $20 each. This lets them take one standard PCI card, in my case a 4 port USB 2.0 card. Then I could connect a couple of external hard drives and…voila…cheap, silent, spacious NAS…with software RAID if you like.
One of the major uses for NAS around my home is music. I have a couple of Slim Devices Squeezeboxes as music playback for the home and office. These are outstanding devices! Truly change-your-life gadgets. They connect to your stereo and stream music off a PC server running a Perl based server software. It just so happens that Michael Herger has created a package called SlimNAS that installs the Slim Server software into FreeNAS. So this little box not only stores the music, it serves it up as well. All in <10 watts.
There in one little gotcha. You can set the BIOS to boot from a USB port, but it will only boot to the devices on-board ports. It won’t boot to a USB 2.0 port on a PCI card. This is minor. I built a 1 GB thumb drive with FreeNAS and SlimNAS, then added a pair of 250 GB HD in USB portable enclosures that I had sitting around. That’s 500 GB of RAID 0 or 250 GB of RAID 1 storage. Total power consumption < 25 watts. Ambient noise contribution to the room…none.
