Re: Backup to USB works but to NAS fails

It's a small white box with 8-ports located on its end behind a bunch
of books with not enough slack wire to move it far enough to read any
of its labels. Having just read the difference between a switch and a
hub and realize that a switch is better. I'm heading up on-site in a
few minutes and will take a look even if I have to unplug everything
to see what it is (everyone should be out to lunch). If it is a hub,
which I suspect, after lunch maybe I'll head over to Fry's and get a
switch with more ports.

You keep saying hub..
I DO hope it is actually a switch.
Also please check the lights on the unit.
Are ALL the connections running at 100mb/s duplex?
That will be a limiting factor on the more entry-level units..

I'm trying an experiment tonight. I've moved the NAS so that it is
attached directly to the first hub in the chain (SBS > hub > NAS)
and will see what happens. Wish me luck.

OH HECK, what was that 5,4,3 rule of ethernet?

Oops.. yes max of 3 bridges (switches) with max of 2 repeaters
(hubs) between.
and even then it's not guaranteed to work.
It's all about the delays introduced within each broadcast domain.
excessive collisions or a 10MB client in the middle domain will
kill the lot.
Realy 2 switches max for and desired route is what to aim for.
with good switches you can stretch this to 3 or even 4


get some second hand HP 2424M (J4093A) switches off ebay.. they
seem to be arround 60$
Hang the wireless units off these, where needed.
the HP units can be trunked..
UP to 4 (or is it 8) 100MB ports can be bundled together to give
you up to 800MB/S (yes 4 ports) 400 one way 400 back = 800
real-world stats should give you about 300mb/s end-to-end
throughput even through 3 units..
