on 64bit platforms it is MAX(3/4 of memory, memory - 1GB) by default.
so for a system with 72GB it should be MAX(54GB, 71GB) which is 71GB.

Dear All,
our storage system running opensolaris b133 + ZFS has a lot of
memory for caching. 72 GB total. While testing we observed
free memory never falls below 11 GB.
Even if we create a ram disk free memory drops below 11 GB but
will be 11 GB shortly after (i assume ARC cache is shrunken in
this context).
As far as i know ZFS is designed to use all memory except 1 GB
for caching....
Thanks in advance
