When configuring a VMware Horizon environment with 1000 linked clones connected to an XtremIO storage system, the minimum number of datastores required to support this configuration, based on best practices, is four. This recommendation ensures optimal performance and manageability while avoiding overcommitment of resources.

The process for determining the minimum number of datastores involves:

Assessing Performance Needs: Evaluate the performance requirements of the linked clones, considering factors such as IOPS (Input/Output Operations Per Second) and throughput.

Understanding XtremIO Capabilities: Recognize that XtremIO's all-flash array provides high performance and low latency, which can support a large number of clones per datastore.

Considering VMware Best Practices: VMware's best practices suggest balancing the number of clones across multiple datastores to optimize performance and manageability1.

Calculating Datastore Requirements: For 1000 linked clones, dividing them across four datastores allows for sufficient distribution without exceeding the capabilities of the XtremIO system.

Implementing the Configuration: Create and configure the four datastores within the VMware Horizon environment, ensuring they are properly connected and recognized by the XtremIO storage system.

Monitoring and Adjusting: After implementation, continuously monitor the performance and capacity of the datastores, making adjustments as necessary to maintain optimal operation.

It's important to note that while four is the minimum recommended number based on best practices, the actual number may vary depending on specific environmental factors and requirements. Always refer to the latest official documentation and consult with Dell support for tailored advice.
