We have been able to provision Fibre Channel storage from our ZFS file systems which give us the benefit of data integrity, deduplication, performance through use of the ARC, L2ARC, and ZIL as needed. Additionally the real benefit to ZFS is our [...]

Now we could go the route of permitting route logins to SSH however this would not be ideal from a security perspective. [...]
