Horizon 2306 introduces the ability to use Persistent Disks for Dedicated Instant Clones. Please find documentation which outlines the general limitations and requirements for Dedicated Instant Clones: Windows Desktops and Applications in Horizon 8 - Using Persistent Disks for Dedicated Instant Clones For Details on Migrations from a Legacy Horizon 7 Environment, please see Guidelines for Persistent Disk Migration from Horizon 7 Environments to Horizon 8 (93091) Image Optimization: Ensure your image is the very best it can be for usage as an instant clone and your infrastructure is configured for an optimal experience: Horizon View Best Practices: Parent Image Creation and Maintenance. (90152)Horizon View Best Practices: Instant Clone Provisioning and Troubleshooting (91265) Capacity Planning: When you configure persistent disks, the default size will be 2GB. Please consider your user base and likely usage to account for future growth. Profile Backup: With Persistent Disks, you store user settings and user-generated data on a disk independent of the VM. Identification and Configuration of an appropriate backup solution is critical to operational continuity and speedy recovery. One option is to complement this technology with VMware Dynamic Manager: Using VMware Dynamic Environment Manager with Local Profiles. This central share can then leverage your existing backup technology. This offers redundancy and a speedier recovery.
