Truly Wow then.. I didn't know you could bind all 4 and get a large
throughtput. But hey, doesn't that mean that you would need a GiG Switch
to realise that speeds or is it that it means 4 diff RJ45s into 4 diff
ports on the switch? I think that's it.

OK. Nice..

Not being a business, Money is a Problem. I'll pass with whatever lands
on my feet and what little money can buy. But it's great to learn about
it and be able to use it when the need comes. (or when money _isn't_ a
problem)

Some ppl argue that software RAID, (not via BIOS) but via LInux Software
RAID is a good _enough_ alternative for something like a small SMB
server.

What's thei buffer? Is the the RAM? I've not seen any options for 32k.
(only like 16MB/32MB/64MB)

You might have just won me over with that statement. (at least for SMB
servers)

A friend of my just purchased some Intel Dual (PCI) NICS. I believe
these are what you're talking about? I've not seen others but I believe
Adaptec makes some too.

Thanks
