One of my colleagues was testing our ZFS prototype (S10U4), and was
wondering what was the limit for ACE's on a ZFS ACL.

Empirically, he determined that he could not add more than 1024 ACE's
either locally or via NFSv4 from a Solaris client (from a Linux NFSv4
client, it failed adding the 209th ACL, and for that matter, after the
failure to add that last entry, it was no longer able to read the ACL,
Complaining that "getxattr" failed).

I haven't found any information regarding a documented limit for either ZFS
itself or NFSv4.

Is 1024 the limit? Is there any tuning that can be done to either increase
or decrease that?

Thanks...
