12 Dec 2011 Integration of LDoms Networking with Networking Enhancements in Solaris 11 [25047]
Focus on Behavior of LDoms Virtual in a Solaris 11 Service Domain

The network stack for Oracle Solaris 11 has been substantially re-architected in an effort known as Project Crossbow, a main goal of which is to virtualize the hard NICs into Virtual NICs (VNICs) to provide more effective sharing of networking resources. Raghuram Kothakota blogs on how LDoms networking is integrated with all the networking enhancements in S11, mainly with project Crossbow. His post is a high-level view of how LDoms virtual switch in an S11 service domain and LDoms virtual network device in an S11 Guest domain.

07 Dec 2011 SPARC T4-4 Processor:: Foundation of Oracle SPARC Supercluster [25043]
Integrates Solaris on SPARC, Exadata, Exalogic

Oracle has produced a true SPARC Engineered System that integrates Solaris on SPARC, Exadata and Exalogic. And this new system is the Oracle SPARC Supercluster, which is built on the new T4 chip and its new architecture, which has resulted in the SPARC T4-4 Server as the the top of the line 5RU model. SPARC Supercluster also includes the integration of Infiniband and the flexibility of Logical Domains (LDoms) as well as a ZFS Storage Appliance to support the Exalogic clustering storage needs, plus Exadata Cells.]

18 Aug 2011 Oracle RAC DB 11gR2 on Oracle VM Server for SPARC (LDoms) [24452]
A 'Cookbook' Approach to the Installation and Configuration

The blog post "Deploying Oracle RAC DB 11gR2 on LDoms Virtualization" is a "cookbook" approach to configuring and installing Oracle Real Application Cluster (RAC) Database 11.2.0.2 on Solaris 10 and Logical Domains on Sun CMT servers (also using ZFS). He concludes that LDom is a good choice for RAC deployment for, among other reasons, it is a virtualized hosted environment; it permits easy reallocation/deallocation of system resources dynamically; it allows for optimized system utilization and space/utility consumption.

14 Jun 2011 Oracle VM Server SPARC 2.1 Released with Important New Features [24260]
Notes by Jeff Savit

With the release of Oracle VM Server SPARC 2.1 (OVMSS) users can now enjoy several new and important features that amount to useful enhancements of this solution. These features are:

  • Live Domain Migration
  • CPU Dynamic Resource Management
  • DTrace enablement
  • Improved allocation and deallocation of CPUs and crypto units

Bug fixes and performance improvements are included in the release as well. A blog devoted to the live migration feature in this release will soon be available. OVMSS was once referred to as Logical Domains (or LDoms) but, whether by that name or by OVMSS, this solution is a virtual machine capability built into Oracle's T-series SPARC Chip Multithreading (CMT) servers, permitting up to 128 domains (virtual machines) on a single server at no extra cost. That last phrase is worth repeating: " ... at no extra cost."
