Friday Spotlight: Oracle VM Server Performance and Tuning Blog

This Friday spotlight announces new blog articles on Oracle VM performance. This series of blogs, started in September, discusses how to evaluate and optimize Oracle VM performance. The articles that have already been published are:

  1. Oracle VM Performance and Tuning - Part 1 - introduced the series and gave a perspective on virtual machine performance.
  2. Oracle VM Performance and Tuning - Part 2 - discussed performance measurement and evaluation, and reviewed Oracle VM CPU, memory, and I/O architecture for both x86 and SPARC.
  3. Oracle VM Performance and Tuning - Part 3 - discussed performance goals, use cases, and policies for virtual machines and cloud environments.
  4. Oracle VM Performance and Tuning - Part 4 - provided an in-depth view of CPU and memory optimization for Oracle VM Server for x86, with details on how to optimize NUMA latency, CPU sizing and over-subscription, and hyper-threading.
  5. Oracle VM Performance and Tuning - Part 5 - discussed the different Oracle VM Server for x86 domain types and how to choose between them for performance and flexibility, and how to leverage huge pages and Oracle VM's CPU scheduler controls.
  6. Oracle VM Performance and Tuning - Part 6 - (new) discusses tuning network and disk I/O performance, which is critical to most workloads.

Upcoming articles will discuss tuning for other aspects of Oracle VM performance, followed by Oracle VM Server for SPARC performance topics.

In summary, while Oracle VM is designed to provide excellent performance "out of the box" performance can be enhanced by selecting the right implementation choices and using best practices.

Friday Spotlight: Oracle VM Server Performance and Tuning Blog

This Friday spotlight announces a new series of blog articles on Oracle VM performance, starting with Oracle VM Performance and Tuning - Part 1.

Oracle VM is designed to provide excellent performance "out of the box" through its architecture and default configuration. Still, there are opportunities to enhance performance for demanding environments by selecting the right implementation choices and using best practices.

The articles will discuss how to measure and evaluate performance, provide tips for performance on Oracle VM Server for x86 and Oracle VM Server for SPARC, and relate experiences and lessons learned.

The first article provides a broad overview of performance in the virtual machine world, with specific examples relating to Oracle VM. Further articles will drill into how to provide optimal performance. Stay tuned!

Friday Spotlight: Oracle VM Server for SPARC Virtual Disk Performance Improvement

A new Solaris update dramatically improves performance for virtual disks on Oracle VM Server for SPARC, providing near-native I/O performance. With this change, virtual I/O is suitable for the most demanding I/O intensive applications under Oracle VM Server for SPARC. Read this article to see more details.

Friday Tips #31

Happy Friday, everyone!

Our tip this week answers a question that comes up often.

Question:
When deploying Oracle Virtual Desktop Infrastructure, how many users can a single server support?

Answer from information in the Oracle's Single Server Solution for VDI white paper:
As part of a single server solution (meaning, the hypervisor, storage, and management pieces are all on one machine and no other systems are necessary), Oracle tested two different configurations and came up with a guideline for how many users these systems can support. Please remember, this is just a guideline and not a guarantee or assurance of performance.

Configuration #1 (this is called the "base configuration" in the paper):

  • Sun Server X3-2L based on Intel Xeon E5 2660 processors
  • 128 GB 1600 MHz RAM (expandable to 512 GB)
  • 16 x 600G SAS-2 10K RPM disks 
  • Based on a customized “Large” configuration on the Oracle store 
  • Targeted at 90-95 users per system

Configuration #2 (this is called the "performance configuration" in the paper):

  • Sun Server X3-2L based on Intel Xeon E5 2690 processors 
  • 256 GB 1600 MHz RAM (expandable to 512 GB) 
  • 26 x 600G SAS-2 10K RPM disks 
  • Offered as “Large” configuration on the Oracle store 
  • Targeted at 180-190 users per system

If you'd like to get some more detail on this, head on over to the Oracle's Single Server Solution for VDI white paper for a lot more info.

We'll see you next week!
