So thanks to Doug at DABCC there is this article - this also contains a downloadable PDF of Credit Suisse's research on Citrix

Is Citrix Making A Broader Virtualization Play?

Implications. In our opinion, one of the Xen developers—either XenSource or Virtual Iron—could represent an attractive target for Citrix, as we believe that hypervisor and associated management solutions would be complementary to Citrix’s long-term vision of offering scalable application and desktop delivery. While these companies’ virtual infrastructure management tools are more immature versus more-established vendors, if Citrix can develop robust management software through increased R&D while leveraging the open source Xen hypervisor, Citrix could establish itself as a strong competitor in both desktop and server virtualization within two to three years. Acquiring XenSource could also strengthen Citrix’s relationship with Microsoft. Conversely, while timing and pricing for any potential transaction is unknown, the near-term implication of an acquisition of either vendor would likely be some EPS dilution.

 

But what really interested me in this research was the listing of all the Competitors in the Hypervisor and Virtualization space on page 14 and that raised Virtugo Software as an interesting tool to increase performance in a VMware environment, If it does what it says can on the tin then it should be a no-brainer for large VMware implementations?

 
Optimize  

virtualSuite Optimize Performance Results

A recent test confirmed that Optimize can enhance the reliability, scalability and performance of a VMware ESX Server. The testing environment consisted of a VMware ESX Server (Quad CPUs, 8 GB of RAM) with 22 guest virtual operating systems. The load tool initially targeted two of the guest operating systems - one running Windows IIS and the other running a Microsoft SQL database server.

The tool was configured to increase the number of concurrent users from 10 to 1000 in order to obtain the metrics below. The initial test was performed with optimization DISABLED and share allocation set to the default level of 1000 shares. Later testing was performed utilizing the same host and configuration with optimization ENABLED by Optimize. The results clearly show that organizations can expect significant gains with Optimize.





Key Features

  • Dynamic resource provisioning
  • Physical and virtual resource prioritizing
  • Manual or automatic tuning
  • Remove complexity of server share management
  • Monitor the health and availability of VMware
  • Remote administration of VMware host servers
  • Comprehensive heterogeneous management
  • Intelligent allocation of resources
  • Discovery and mapping of VMware
  • Real-time share optimization

Dramatic Benefits

  • Improve response time up to 42%
  • Increase transaction throughput up to 50%
  • Manage up to 25000 virtual servers and up
  • Administer 20 to 200 operations per second
  • Expand VM processing capability by more
  • Extend hardware investment and lower total
  • Enhance reliability, scalability, productivity
  • Accelerate end-user response time during peak
  • Improve application availability and quality
  • Easily adapt to changing business needs

Application Load Test

Load tool
WebLOAD version 5

ESX Host Configuration
Number of CPUs: 4
Hyper-threading: Disabled
Amount of physical memory: 8 GB
ESX version: 2.5
Number of VMs: 22
Guest operating systems: 15 Windows 2000 and 7 Windows 2003

Computers used in the test
SQL Server (Windows 2003 Server) 10.201.0.46
IIS (Windows 2000 Server) 10.201.0.33

Application Load Test Results
Overall, the load test revealed a 33% increase in transactions and a 35% decrease in response time for systems with 10 to 1000 users. For systems with 100 to 1000 users (highlighted below), the load test revealed a 50% increase in transactions and a 42% decrease in response time.

My favorite part of your postings are the advertisements. That's what has been missing from Geeks with Blogs!

Keep up the great work.

How do you get paid? Do you expect these people to spend their hard earned money on web servers and developers and software so you can have a post without an ad? I really hate to see these types of posts. You get free info and all sites like dabcc and many others ask is to support their partners. That is much to ask. I guess some people just want something for nothing and then they want to bitch about getting it free. Not very nice if you ask me.
