![]() ![]() ![]() Persistent disks are not supported with Instant Clones.Composer does not need parent virtual machines.Prior to Horizon 7.13, Instant Clone pools always create Parent machines no matter the size of the Instant Clone pool.See the Smart Provisioning YouTube video for an overview. For lower density pools, Horizon 7.13 supports Smart Provisioning, which eliminates the need for “Parent” machines when there are less than 12 single-pool VMs per host.If you have six hosts and three datastores containing instant clones, then Horizon creates 18 parent virtual machines. These “parent” machines are powered on and consume CPU/Memory/Disk resources. Instant Clone pools create “Parent” machines on each ESXi host for each datastore.The master VM snapshot is copied to every LUN containing instant clones.Horizon 7.1 and newer support Linked Clones for RDS Pools.Horizon 7.3 and newer support dedicated desktop pools.Horizon 7.9 and newer support delaying desktop refresh (not recommended), just like you can with Composer.View Storage Accelerator must be enabled. ![]() Virtual Machine hardware version 11 or newer.Since Composer was removed from Horizon 8, start migrating to Instant Clones. All editions of Horizon 7.13 includes Instant Clone licensing.Composer features like Disposable Disks and disk space reclamation are not needed with Instant Clones.With Composer, rebalance is a manual operation.If multiple datastores, rebalance is automatic.Faster provisioning and recompose, and lower IOPS during these operations.Here are some advantages of Instant Clone over Composer: In general, use Instant Clone, if possible.
