Horizon does not require any special configuration to work with PowerStore. The storage is presented as block storage volumes discoverable through vCenter. When the pool is created, the volumes are visible as usable disk.
For this test Horizon was configured to use all 16 datastores for VM creation across all three pools. This spreads the virtual desktops evenly from all three pools across all datastores. The goal is to load balance all storage for best performance and consistency.
The application volumes are used in a round robin fashion to provide the most consistent performance as well. With AppVolumes, distributing access across all six volumes makes the access time consistent for all users.
Based on performance testing under load, the following settings are used:
The numbers were derived from latency under load and the impact of instant clone provisioning. Under full load, the system performed well even with user logouts and VM cloning.
