    Current iSCSI recommendations with large RAM?

    TL;DR: I think I am hitting a well-known ZFS issue where iSCSI is tanking because large NAS RAM is causing large transaction group sizes to be used, causing server-side timeouts on iSCSI. The most recent advice on this is quite old on these forums, and not really suited to 11.0/11.1. I also...
