View Full Version : Multiple SLIM Devices

Is it possible to have ONE slimbox in one room, a second SLIM box in another room, a third slimbox in a third room etc...and to have all of those devices accessing the same PC in one room.

If this IS possible, can each separate box access different music at the same time, or will each box only cope with one feed.

If all of this is possible anyone know what the limit for boxes is? So if I had one hundred rooms [and lived in a bavarian castle!] could the ONE pc cope?

Thanks

Yes

Both, same music or different music.

If it was fast enough. :) Maybe someone else has an answer for the
scaling question.

Yes, in fact this is the exact architecture the devices were
desinged for.

You can have each device operate independently so that they are
all playing different music at the same or you can syncronize
them if you wish to control all of them with one box and have
them play the same thing. It's your choice. The one thing I'm
not sure of (I don't syncronize mine) is if you can only
syncronize some of them. For example, I'm not sure that if you
had say five Squeezeboxes and you wanted to syncronize three of
them but have the other two play independently that you could
accomplish that. I'm sure someone else on this list can easily
answer that though.

My understanding is that you are only limited by your hardware.
If your server and bandwidth can handle the workload then you
could have 100 or more devices. I'm not sure of the hardware
spec's it would take to do this. The Slim Devices FAQ only
states that "even a low-end PC can service more than a dozen
Squeezeboxes" so maybe a nice high-end PC could easily service
over 100.

Mix and match! I only have 3 slimp3s, so I've only been able to try [3
independent, 2 synchronized + 1 other, 3 synchronized] and not two
different groups of synchronized players, but I haven't had any trouble
with turning synchronization on and off in any of those configurations.

This is partially dependent on the number of tracks in your library, the
bitrate of the tracks that you're playing (2 low bitrate mp3s are going
to require less than 1 FLAC, for instance), the available disk bandwidth
and the available network bandwidth. While each track generally doesn't
require that much bandwidth, there are some contention issues that may
come into play when you get close to your capacity. While streaming a
single track doesn't come anywhere close to saturating any reasonable
disk drive, playing two tracks requires that the disk heads bounce back
and forth between the two files, introducing seek time into the
equation, which in turn absolutely ruins the average available disk
bandwidth. Caching helps some, but with 100 different tracks playing,
you need a whole lot of ram available. You'd also need a fairly robust
network to handle multiple tracks. When I got my first 2 slimp3s, I
still had a 10 megabit unswitched hub, and there was about a half second
delay between the two. Replacing that with a 100 megabit full duplex
switch helped tremendously, so that it acts like a much more expensive
whole-house system now.

I think there is somebody on the list running a resort with a dozen or
two slimp3s, but I don't know if he has them all on the same server;
last I knew, he still had some concerns about guests in one area
interfering with guests in others, and I don't know if he fixed that by
hacking the software or by running one server per guest house.
