That's why. I'm looking to essentially build a slave box as a home made
external disk cage instead of buying a very expensive fibre channel or
scsi raid box. I'm not intending for the slave machine to be available
on the network - i'd like to have it directly connected to the server.

We have a need for a very large filesystem and to do it in one machine
would mean a huge power supply (or two), a huge case and a motherboard
to handle it. A better and more extendible solution seems to be to use a
whole other box for more disks and ethernet cards are a whole lot
cheaper than the alternatives

AoE looks like the fella for us, but i'm wondering how stable and
reliable it is. I suppose we could use gnbd or drbd or any of those
things either - we just need something that will work reliably. Sadly we
lack any hands on knowlege of how these things perform in the real world
so i'm looking to see what people have to say

John
