After 2 month LoginVSI extensive tests, I finally published this performance white paper.

This white paper documents the results of SimpliVity-led testing to provide evidence of these efficiency gains on Citrix XenDesktop. Two Citrix XenDesktop provisioning methods, Machine Creation Services (MCS) and Provisioning Server (PVS), were used during the tests. All performance testing utilized Login VSI (http://www.loginvsi.com), the industry-standard load testing solution for virtualized desktop environments, and all testing configurations and results have been validated by Login VSI. These tests offer insight in to the latest performance results of Citrix XenDesktop 7.6 on SimpliVity OmniStack 3.0.

Summary of Results

The performance testing illustrates SimpliVity’s ability to deliver an excellent end-user experience in VDI deployments as the environment scales.

Highlights include:

1. Performance at scale: Consistent, very low VSIMax Average < 2000ms measured throughout XenDesktop Hosted Shared deployments and Hosted Desktop deployments.

2. Reduce capacity and IO requirement: Inline deduplication and compression rate above 20:1.

3. With four (4) SimpliVity nodes on Hosted Shared Desktop deployments, 800 users can be supported with MCS and 1200 users can be supported with PVS RAM Cache option.

4. With four (4) SimpliVity nodes on Hosted Desktop deployments, 600 users can be supported with MCS and 800 users can be supported with PVS RAM cache option.

5. PVS “write cache on RAM with overflow to disk” option can almost eliminate IOPS.
