The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

You have two options for provisioning VMs on a HyperFlex pod. The option you choose depends upon how many VMs you want to provision at one time and whether you want your end users to be able to provision VMs on a HyperFlex pod.
VDC-based VMs enable a user with administrative permissions or your end users to create one VM at a time. Some HyperFlex-specific confguration is required in the VDC and its related policies.
ReadyClone VMs enable a user with administrative permissions to provision multiple VMs at one time. ReadyClone VMs perform rapid cloning of many VMs through HyperFlex technology, rather than the one and many VMware technology. All of these VMs must be based on the same VM template. See the Cisco HyperFlex Systems Administration Guide for more information about ReadyClone VMs on Cisco HX Data Platform.
You can use a Virtual Data Center (VDC) to provision a VM on a HyperFlex pod through the standard Cisco UCS Director VM provisioning process. If you provision VMs with VDCs, you must ensure that all HyperFlex VDCs have the recommended configuration.
See the Cisco UCS Director Administration Guide for more information about VDCs and how to provision VMs.
ReadyClone VMs enable you to rapidly create and customize multiple cloned VMs from the same VM template. When the cloning operation is complete, the ReadyClone VM is a separate guest VM with its own operating system.
Changes made to a ReadyClone VM do not affect the VM template. A ReadyClone VM's MAC address and UUID are different from those of the VM template.
For more information about the features, benefits, best practices, and guidelines for ReadyClone VMs, see the Cisco HyperFlex Systems Administration Guide.
Before you provision one or more ReadyClone VMs, review the following guidelines. For more information about ReadyClone VMs, see the Using HX Data Platform ReadyClones chapter of the Cisco HyperFlex Systems Administration Guide.
You must have Cisco UCS Director administrative privileges to provision ReadyClone VMs in the Cisco UCS Director Admin Portal.
The VM template that you use to create ReadyClone VMs must meet the guidelines provided in the Cisco HyperFlex Systems Administration Guide.
You can simultaneously provision between 1 and 256 ReadyClone VMs from a single VM template.
All ReadyClone VMs that you provision at the same time must use the same customization specification in VMware vCenter for the guest operating system (OS) settings in all VMs. The guest OS can be either Linux or Windows.
