Yeah, but that is as easy as
zpool create tank raidz2 dev1 dev2 dev3 dev4 dev5 dev6 etc.
zfs create tank/bigdisk
But I'd go one step further and use one of SUNs OpenStorage devices.
Once you have a lot of no-name JBOD SATA-drives, the inability of
Solaris to light-up the yellow light of the broken one will make it
painfully obvious that while one can spend to much on storage, one can
as easily spend too little...
If you really want to go with a HW controller, try Areca or the high-
end 3Ware models.
As mentioned in any ZFS document, when you use a HW-raidcontroller,
the OS never knows if a drive is broken or showing errors. The HW
hides that from the OS.
You have to have closed-source drivers like the HP utils to tell you
If your data-set will, over the lifespan of that server, never grow
beyond the original size of the array, then you can go with a HW-
Otherwise, go ZFS.
