What's up with LDoms: Part 6 - Sizing the IO Domain [29085]
Overcoming the Bottleneck with More Precise Compute Resource Allocation
Continuing his series on "What's Up with LDoms," Stefan Hinker turns to Sizing the Control DomaIn and the IO Domain, asking how much CPU and memory the Control and IO-domain need to provide bottleneck-free virtual network and disk services to the guests. The bulk of the CPU resources will be used by disk services, network services and live migration. A single core on T4 for each IO domain should be sufficient. On larger systems with higher networking demands, two cores for each IO Domain might do. If your CPU resource allocation requires additional adjustment, Hinker recommends using mpstat (1M) and DimSTAT for further analysis.

The USE Method: SmartOS Performance Checklist [28989]
Comprehensive System Performance Analysis Tool: Cloud, Physical Resources and Software
The USE Method, as Brendan Gregg describes it, provides a strategy for performing a complete check of system health, identifying common bottlenecks and errors. For each system resource, metrics for utilization, saturation and errors are identified and checked. Identified issues are then investigated further. Gregg provides check lists for cloud limits, physical resources and software resources. His example employs a USE-based metric list for use within a SmartOS SmartMachine (Zone), such as those provided by the Joyent Public Cloud. These use the illumos kernel, and so this list should also be mostly relevant for OmniOS Zones, and to a lesser degree, Solaris Zones.

OS-Level Virtualization with Oracle Solaris Zones and Linux Containers [28795]
Requires No Additional Software Layer
In the third article of a series on Oracle VM Server for SPARC and Oracle VM Server for x86 Detlef Drewanz posts about the operating system level of virtualization. Oracle Solaris Zones and Linux Containers offer a lightweight virtualized runtime environment for applications. Unlike hypervisor-based virtualization, they do not add an additional software layer. With Oracle Solaris Zones and Linux Containers, there is one OS kernel that is shared by many zones or containers. Oracle Solaris Zones technology has existed since Oracle Solaris 10, and Linux Containers technology is available as a Beta version for Oracle Linux with the Unbreakable Enterprise Kernel.

Software Enhancements Enhance Capabilities for Oracle SPARC SuperCluster [28785]
Consolidation, Cloud Deployment Are Accelerated
New software enhancements to SPARC SuperCluster allows it to deliver 10x application consolidation ratios using the new layered, zero-overhead virtualization combined with the database offload functions of Oracle Exadata Storage Servers. SPARC SuperCluster customers can now deploy mission-critical, multi-tenant applications faster, using Oracle Solaris Zone workload isolation capabilities; virtualize Oracle Databases running on Oracle Exadata X3 Storage Servers within Oracle Solaris Zones; deploy multiple Oracle Database and enterprise application domains on each SPARC SuperCluster compute node; and re-allocate CPU and memory resources across existing SPARC SuperCluster domains and zones.
