14 Jan 2015 kernel zones vs. fs resources [40349]
By Mike Gerdts

Mike writes, "Traditionally, zones have had a way to perform loopback mounts of global zone file systems using zonecfg fs resources with fstype=lofs. Since kernel zones run a separate kernel, lofs is not really an option. Other file systems can be safely presented to kernel zones by delegating the devices, so the omission of fs resources is not as bad as it may initially sound.

For those that really need something that works like a lofs fs resource, there's a way to simulate the functionality with NFS. Consider the following system..."

08 Jan 2015 Best Practices for Oracle Solaris Kernel Zones [40299]
by John Levon

"Oracle Solaris Kernel Zones, available as of Oracle Solaris 11.2, are the newest type of Oracle Solaris Zone. Kernel zones provide all the flexibility, scalability, and efficiency of Oracle Solaris Zones while adding the capability to have zones that have independent kernels. This capability is highly useful when you are trying to coordinate the updating of multiple zone environments that belong to different owners.

With kernel zones, the updates can be done at the level of an individual kernel zone at a time that is convenient for each owner. In addition, applications that have specific version requirements can run side by side on the same system and benefit from the high consolidation ratios that Oracle Solaris Zones provide.

This article discusses general best practices for deploying kernel zones..."

02 Jan 2015 Use both LDoms and Solaris Zones combined [40125]

"On current SPARC Systems you can choose to use LDoms and/or Zones:

Using LDoms you are able to run independent Solaris Versions on the same SPARC Server. Dedicated Memory and CPUs makes LDom very efficient (Zero Overhead). LDoms can be live migrated to other SPARC Servers.

Solaris Zones are Application Environments running on a Solaris OS. Using Solaris Zones you run your Applications in different Versions and different configurations on the same Solaris OS..."
