Are you looking for the software updates?

For those of you still not used to finding your way around MOS (My Oracle Support), here are the patch numbers you can use to search for the 7000 ZFSSA patch you are looking for:
12780572 - This is the latest ZFSSA release, version 2010.Q3.4 - from July 22, 2011.
You want this.
11887647 - This is version 2010.Q3.2.1 - This is the minimum version you need to be on in order to then upgrade to Q3.4
12736304 - This is the 7000 NFS plug-in patch for Solaris Cluster version 1. You need this if you have a cluster server running Oracle Solaris and you want to NFS to a 7000. You load this on the cluster, not on the 7000. It's small enough that I have provided it here.
