I am helping a friend who is build a storage server for his company  
and I have advocated for Solaris and ZFS.
But now we are having trouble to find  any good SATA controller for  
12+ disks, there are Areca cards, but they seems very flaky (24 port  
support, but hangs with more than 12 in JBOD mode, hangs on disk  
failures etc).
The AOC-SAT2-MV8,AOC-USAS-L8i  have been mentioned, but it had  
problems with device numbering and/or as I understood it no support  
for hot plugging.
Isn''t  there any supported PCI.* SATA card with at least 12 ports that
do work and have a real driver supporting hot plugging/cfgadm- 
operations?
The HCL does not tell you everything, and scanning the lists did not  
show any consensus regarding this. This seems to have been a problem  
for years, I tried to find a card for myself a while back.
