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.

The series on the network virtualization features of Oracle Solaris 11 Express written by Jeff Victor continues with his third post, which deals with the creation of virtual network elements (VNEs). Victor explains that his example employs an old Sun Fire T2000 with a single SPARC CMT (T1) chip and 32GB RAM. He pretends to be implementing a 3-tier architecture in this one system, where each tier is represented by one Solaris zone. This mythical example provides access to an employee database, he continues, and the 3-tier service is named 'emp' and VNEs will use 'emp' in their names to reduce confusion regarding the dozens of VNEs created for the services this system will deliver. Victor remarks on the convenience of the dladm(1M) command in Solaris that one can use to create, destroy and configure datalinks such as VNICs. He illustrates his post with numerous code samples.

For many systems, the cost of the solution can be dominated by the Oracle license fee.
A systems solution with CPUs that have a lower Core Processor Licensing Factor
may end up with a lower overall cost than one with a smaller number cores that have a higher Oracle Licensing Factor (aka multiplier).
Oracle has set the multiplier for the newest SPARC chips - the SPARC T3 and the SPARC64 VII+ - very aggressively. The SPARC T3 has a multiplier of 0.25 - the same as the 1.0 GHz UltraSPARC T1 (as featured in the T1000 and T2000). The SPARC64 VII+ has a multiplier of 0.5, which is less than the 0.75 multiplier of the UltraSPARC IV, IV+ or the SPARC64 VI, VII which powered older systems like the V490, E6900 and E25k servers.
Note: the IBM POWER6 and POWER7 systems have a multiplier of 1.0.
The latest AMD and Intel systems a have multiplier 0.5, twice that of the SPARC T3.

"Setup, Tuning, Workload Performance Guide for Sybase Adaptive Server Enterprise (ASE) on Sun Storage 7000 Systems" by Sanjay Gianchandani outlines the procedure for configuring the Sybase Adaptive Server Enterprise (ASE) database server to use Oracle's Sun Storage 7000 Unified Storage Systems as a storage unit.

In September 2008, medical products maker ResMed decided to replace 160 PCs with Sun Ray 2 Thin Clients, and purchased two SPARC Enterprise T2000 Servers with chip multithreading, and four Sun Fire X4440 Servers to support its new solution. According to ResMed, IT productivity has increased by the equivalent of two additional IT staff, and the company has saved about $267,850. The Sun solution also increased security and substantially reduced energy costs as well as the noise-level.
