My question regarding the 7000 series storage is in more of the
perspective of the HOST side ZFS config. It is my understanding that
the 7000 storage displays a FC lun to the host. Yes, this LUN is a
ZFS lun in the 7000 storage, however the host still sees this as
only one LUN. If I configure a host based ZFS storage device on top
of this LUN I have no host based zfs redundancy. So do we still need
to create a host based ZFS mirror or a host based ZFS raidz device
when use a 7000 series storage array?
It is a matter of how much is good enough. You don't have to use a
mirror from the host, but there is still less chance of data loss or
interruption if you do, and particularly if the devices are hosted on
different storage arrays so you can keep on trucking if one goes down.
