Solaris10/ZFS

[Darin Perusich]

You'll likely need to disable cache flushes or you're going to see poor
performance to any mailspools on the SAN because of the array NVRAM. You
can either disable this on the SAN or by setting a kernel parameter. See
http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#Cache_Flushes
for details.
