The density of data on VDI tends to be high because Horizon VDI environments typically use data-reduced clones. With profile-redirection technology like VMware DEM, clone pools appear as persistent to users. DEM enables users to personalize their desktop, but pools can still employ the benefits of nonpersistent VMs. Keeping the VMs small and clean improves performance and recovery time.
The system is configured with 16 1TB datastores for virtual desktops and two 1TB volumes for file storage. Since any volume can be expanded at any time, these size recommendations are starting points. All volumes are also thin provisioned and have space reclaim enabled. Thin provisioning and on-demand volume resizing maximize storage efficiency.
