I've been considering, on setting up and connecting an isci drive as an mirror to my vdev. Now, I am curious on your thoughts, on if this is an insane idea that is nothing but trouble or what. Now, I have read up and sharing an isci target over the network can/will hog/overwhelm the network connection to the point of needing a dedicated network connection just for isci. I have seen some old posts recommending setting up a HAST setup would be a better idea. From my understanding (limited to what information I've read), HAST seems to be way overkill in the basic thought, and a disadvantage in that the secondary side would become the Primary.
To describe the setup I am envisioning, be 2 computers on the same network Master and Slave. The Slave computer is hosting the isci drive/device to the Master computer. The Master computer is setup as a simple mirror internally (2 drives in the Master computer) and the isci drive added into make the mirror a 3 way mirror. Unlike the HAST setup, the Slave computer (isci host) NEVER gets promoted, it is to always stay as a secondary device. With this setup being a mirror setup, even if the isci drive goes offline, it should just be brought back up to date once it comes online.
