Take the following example, where i'm using files but it's the same with real devices.
This will tolerate 1 to 2 device failures.

If two devices fail from one top level vdev (mirror-N) you will lose data.

I would strongly suggest using odd number of disks and keeping one hot spare in pool.
In your configuration, get one more disk if you really love your data.

Code:

[root@gimmick ~]# ls -dl /zones/test/disk*
-rw------T   1 root     root     104857600 Jun 16 02:48 /zones/test/disk0
-rw------T   1 root     root     104857600 Jun 16 02:48 /zones/test/disk1
-rw------T   1 root     root     104857600 Jun 16 02:48 /zones/test/disk2
-rw------T   1 root     root     104857600 Jun 16 02:48 /zones/test/disk3
[root@gimmick ~]# 

[root@gimmick ~]# zpool status testpool

zoneadmd

zoneadmd(1M)															      zoneadmd(1M)

NAME

       zoneadmd - zone administration daemon

SYNOPSIS

       /usr/lib/zones/zoneadmd

       zoneadmd is a system daemon that is started when the system needs to manage a particular zone. Because each instance of the zoneadmd daemon
       manages a particular zone, it is not unexpected to see multiple zoneadmd daemons running.

       This daemon is started automatically by the zone management software and should not be invoked directly. The daemon  shuts  down  automati-
       cally when no longer in use. It does not constitute a programming interface, but is classified as a private interface.

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWzoneu 		   |
       +-----------------------------+-----------------------------+
       |Interface Stability	     |Private			   |
       +-----------------------------+-----------------------------+

       svcs(1), zlogin(1), svcadm(1M), zoneadm(1M), attributes(5), smf(5), zones(5)

       The zones(5) service is managed by the service management facility, smf(5), under the service identifier:

       svc:/system/zones:default

       Administrative  actions	on  this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M).  The ser-
       vice's status can be queried using the svcs(1) command.
