L2ARC devices are version 10, the last Solaris 10 rease I saw was version 4. However we are working on getting the L2ARC into the hands of customers much sooner - they won''t need to wait for a Solaris 10 backport. Brendan -- Brendan [CA, USA]

In what form you want to provide it then? (Putting fw aside). -- Best regards, Robert Milkowski mailto:milek at task.gda.pl http://milek.blogspot.com
> When will L2ARC be available in Solaris 10?My Sun SE said L2ARC should be in S10U7. It was scheduled for S10U6 (shipping in a few weeks), but didn''t make it in time. At least S10U6 will have ZIL offload and ZFS boot. -- This message posted from opensolaris.org
