Hi all,Solaris Zones are more similar to AIX WPARs.Using Solaris Zones you create virtual servers at the kernel level so basically you have one Solaris per physical server with several virtual Solaris servers.If you use e.g. Sparc server you can physically partition server and install separated Solaris in each partition (and then of course if you wish createseveral virtual servers called Solaris Zones :-) ).RegardsPrzemekOd: "De DBA" <dedba_at_tpg.com.au>Do: oracle-l_at_freelists.org; Wysłane: 9:42 Środa 2014-07-09Temat: Re: Sun Servers
Containers, zones and partitioning are used interchangeably but do
not necessarily refer to the same thing. I think it is important to
realise that machine partitioning into separate domains is (on Sun
boxes) done at the OpenBoot level, not in the OS. The Solaris zones
(in Solaris11) are merely logically separated process spaces. This
can be seen in the root zone, where all running processes including
those in zones are listed by tools such as ps(1). I believe that
Solaris Zones are comparable to AIX LPARs, at least in this respect.
In OEL you could use the OVM/Xen kernel for this purpose.
As far as I am aware (correct me if I'm wrong) when the machine is
partitioned, resources such as CPU and memory cannot be shared
between domains. When using logical partitions, a.k.a. zones, the OS
resources can be pooled and shared between zones.
The ability to partition a machine may be an advantage, depending on
your intended use. I've never seen it implemented.

Thanks Mark. That sounds pretty cool. One of the big selling points I got from Oracle was the ability to partition machines.

I have been very impressed with what the Solaris 11.1/Zones/ZFS combination provides. We have the database servers on the X4-2L mounting a ZFS storage server over dNFS via a 10G and 1G combiation. The X4-2L have been provisioned with 4xF80 flash cards in them as well that have allowed us to allocate specific flash devices to different zones as required. It is a very powerful and flexible platform to deploy databases and application servers on.

They will be standalone servers though not ODA's.

I'll keep that in mind. Factory install of Oracle Linux is an option. I did all my OCP practicing and testing on Oracle Linux and I liked it.
