Well, in the mean time I have my four computers connected via a 4 channel WLAN Router. However, after what cm said at the beginning of this thread, I never tried to stream the samples over the router from another computer, but I may test that soon.

The router model is a: ZyXEL P-660HW Series

.

angelo, the 660HW has a built-in 10/100 Mbit switch (means each port can transport a maximum of 100 megabit/sec) - one stereo channel 24 bit 44,1 kHz needs ~2 mbit/s, so in theory you can transport almost 50 *voices* simultaneously (subtract at least 20% for real life)

conclusion: forget 100 Mbit network for streaming (and of course WLAN too) - it's just good to copy something from A to B or browse the internet ...

So, in theory, a gigabit network would be fine?

What about the hard drive perfomances - if you're accessing it from numerous computers at the same time - isn't it going to be a problem?

my advice would be: don't toch such a configuration without knowing, or at least having someone who knows - too many factors to consider (not some network technician but someone who also knows how sampling works)
of course then harddrive performance will become an issue (but sometimes it is already on the local computer).
gigabit is basically fine, theoretical 500 *voices* to stream possible (remember: subtract at least 20% overhead / headroom), but often computers do not even get such a data throughput over their internal bus ...

the best method would be: KIS - keep it simple. share only data which would be redundant otherwise and keep heavily used samples as close as possible to your processor ...

Ok, thanks - good to know.

I am not sure this is totally related, but in terms of *where* the samples are being stored, would you recommend :

1/ On the SATA system drive
2/ On an external, (IDE) FireWire drive?

Jerome

I think that for this purpose classic Ethernet connection is a no way !

iScsi should work, but it will be cheaper and more simple to put a hard disk in (or near) the computer.

Wouldn't the ultimate system for the VI's be one that utilized Fiber Channel? Have the samples on a dedicated server (Xserve) using 3-3GHz Mac Pros connected via Gigabit Ethernet on a LAN. I think all doubt about throughput would be solved; and you would have one of the most powerful, kick a%$ work stations on the planet.

for fibre channel some things have to be taken in consideration:
- we currently see the move in fibre channel technology from 1 Gbit over 2 Gbit (like XServe has) to 4 gbit and you hou have possible connections over copper or optical cable.
- there are 2 possible network designs - switched fabric or arbitrated loop.
- usually fibre needs 100 MHz 64bit PCI-cards to make use of the full bandwidth (would be hard to get for notebooks), some cards are compatible to 32bit 66 MHz slots but then would not gain the full performance.
- fibre switches are significantly more expensive than ethernet switches
- XSERVE has to be configured to not cache data, otherwise the theoretical performance will not be available for sample-streaming.

doesn't sound like an easy studio-setup i'd say ...

The other problem is that xSan technology is not compatible with ProTools. If you want to have a central data server and use ProTools, it is better to use solutions based on iSCSI (like GlobalSan from StudioNetworkSolutions).

I was speaking of desktop Macs. Thanks, you guys just stopped/saved me from spending a lot of $$$. [H]
