Juni 2006 (Solaris 10)
ZFS was available before June 2006. It appeared in Solaris Express/OpenSolaris in late 2005; June 2006 was the Solaris 10 6/06 release, not the first release of ZFS overall.
Full reasoning
The infobox labels June 2006 as the first release of ZFS, but Oracle's own Solaris documentation shows that ZFS was already present in Solaris Express 12/05. OpenZFS's project history likewise lists 2005 as the year ZFS source code was released as part of OpenSolaris.
So June 2006 is better understood as the date ZFS reached the Solaris 10 6/06 update, not the first public release of ZFS in any form.

Weiter gibt es zwei RAID-Z genannte Implementierungen.
ZFS has three standard RAID-Z levels, not two: RAID-Z1, RAID-Z2, and RAID-Z3.
Full reasoning
This sentence says there are two RAID-Z implementations, but official ZFS/OpenZFS documentation lists three standard RAID-Z fault-tolerance levels:
raidz/raidz1(single parity)raidz2(double parity)raidz3(triple parity)
Oracle's Solaris ZFS documentation explicitly names all three levels, and the OpenZFS project page does the same. The article itself later mentions RAID-Z3, which also conflicts with this sentence.
