Hello.
I wouldn't advice OpenSolaris for critical servers. You should pay for support
or use sometimes very unstable /dev releases. If you like zones + ZFS, you
could look at Linux configuration (e.g. LVM + OpenVZ or LVM+kvm), it would be
more familiar to you) or (if you want something new and stable ) - FreeBSD +
Jails (FreeBSD Zone analog).
You don't have to use /dev - you can stick with stable releases which is
default if you install OS 2009.06
Then you *can* buy a support for it from Sun. Only critical and security
updates will be provided + major updates every 6 months or so. Then
updates can always be applied to a new BE (Boot Environment) so if
something goes wrong you can reboot back into original BE which hasn't
been modified. This is really great technology - yes, RedHat stated
recently they would like to work on something similar for Fedora in the
future... But they not there yet (not to mention that it will require
btrfs which needs some extra years to become beta quality...). Then
managing LVM is a joke especially comparing it to ZFS. OpenVZ or Jails -
well they do work but they are nowhere near Zones aspecially when it
comes to observability.
While there is still a long way to go with Open Solaris if you consider
*BSD or Linux in order to use Open Source software I would definitely
consider using Open Solaris as well.
