Sure, I understand what you're saying, but the question is: If they can do it with a cheap device like this, then surely one should be able todo it with a normal / server motherboard? Obviously they won't tell us their secrets, so I need to dig around to see how todo it myself. This particular device has a eSATA slave + eSATA Master mode. i.e. I can connect another device to this one and they both work together, and then when I connect the first one to my PC, I have 2 HDD's - i.e. a cheap JBOD implementation.
If you are going to pass eSATA straight through, why would you want the other motherboard involved at all instead of just using an external eSata enclosure?
I'm trying to build a dense eSATA enclosure with say 16 or 24 drives :)
I'm trying to see if I can setup a Linux JBOD on a server chassis with say 16 HDD's or something, and then connect it to another server via eSATA - i.e. building a cheap scalable SAN.
It might make sense to RAID a bunch of disks locally, and export the combined device as iscsi.
The 1GBE LAN is a bit slow. SATA can push 6GBe, which is 6 times faster than 1GBe. And, 6 ports on a LAN switch is a waste. Our 10GBe switches are saturated (all ports filled) and very expensive. So I'm looking at cheaper options, and thought eSATA could do the trick quite well.
P.S. You actually do get USB cross-over cables: http://en.kioskea.net/faq/342-connecting-two-computers-with-a-usb-cable
- they work quite well. They're not as fast a gigabit but works very
well for older PC's without LAN.
I thought those were really implemented as back-to-back ethernet converters.
Yes, probably. But they work over USB so it's very handy.
