Jeff, what you did is exactly what I want todo as well
And, while thinking about how todo it on the cheap, I thought about
using eSATA for it.
The only options I could find what SATA port replicators, but they're
limited to 4/5 ports each. And I can't find a supplier in our country
for them, so I guess I'll have to import them, which will end up
costing an arm and a leg again. Our import duties are expensive.
Which SAS expander did you use? Our local SuperMicro suppliers have
limited products available so if I need something that they don't
have, I'll have to convince them to get it for me.
Upto now they've sold me full blown servers with iSCSI interconnects,
which is expensive if I don't actually use the motherboard, CPU or RAM
for anything useful.
I'm also considering going another route, but it seems that suppliers
in our country simply don't like selling loose components. Why, I
don't know, but I guess someone has to milk the poor clients of their
