Re: Backup to USB works but to NAS fails



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..
