Yes, you can have different pools assigned to different cluster nodes. A common set up with two hosts is to run one pool and host one, and another pool on host two. It’s a way of leveraging all the resources available and having reasonable failover in the event of a node’s unavailability.

And could it work using 2 SAS controllers per host connecting each to different chains? Like Controller 1 Host 1 -> Enclosure Chain 1 Controller 1 Host 2 -> Enclosure Chain 1 Controller 2 Host 1 -> Enclosure Chain 2 Controller 2 Host 2 -> Enclosure Chain 2
each node serving 2 volumes per chain?
In Kubernetes environments, one can also leverage OpenEBS cStor for replicated pools across multiple nodes:
cStor Data engine makes it possible to run ZFS in user space and use a collection of such ZFS instances running on multiple nodes to provide a replicated storage resilient against node failures.
