Oracle Workloads – Where Eagles Dare !!!

The previous blog post ’ PVSCSI Controllers and Queue Depth – Accelerating performance for Oracle Workloads’ purpose was to raise awareness of the importance of using PVSCSI adapters with adequate Queue Depth settings for an Oracle workload.

This blog focuses on the implementation of Oracle SAME (Stripe and Mirror everything) technology using Oracle ASM along with using multiple VMware PVSCSI controllers with queue depth for PVSCSI controllers and VMDK’s set to maximum to achieve maximum performance for Oracle workloads.

This blog

• Is not meant to be any kind of performance study or bake off any sort
• contains results that I got in my lab running a load generator SLOB against my workload, which will be way different than any real-world customer workload, your mileage may vary
• remember, any performance data is a result of the combination of hardware configuration, software configuration, test methodology, test tool, and workload profile used in the testing.
