The density of data on VDI tends to be very high because many Horizon VDI environments use data-reduced clones. With profile-redirection technology like VMware Dynamic Environment Manager (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 was configured with 16 2TB datastores for virtual desktops and 6x200GB volumes for application storage. Since any volume can be expanded at any time, these are only starting points. All volumes are also thin provisioned and have space reclaim enabled. This maximizes storage efficiency.
