Hi there,

There’s a good chance this is well known documented and I just don’t know what it’s called so bare with me.

My Setup is currently a Server Chassis that has a LSI 9300-8e, I run two cables from that into a 24 Bay Box below it that has a backplane with 4 SAS connectors.

I then use the other two connectors to run back out and connect to the second 24 Bay Box and this all works nicely.

I’m looking at getting a 3rd box to expand further and it got me wondering if the only way to connect this is by running another 2 cables from the 2nd box to the second box… or is it possible to create a ring where one of the ports on the 9300 goes to Box 1, the other goes to box 3, and both of the backplanes within them connect to Box 2?

Reasoning is that now It’s getting a little large I’d prefer to have the ability for say Box 1 to be taken off line while drives from Box 2 and 3 are still available?
