Elements
-
Element Type Required Modifiable Since Deprecated Description AutomaticNetworkPoolReference AutomaticNetworkPoolReferenceType No always 5.9 Indicates that the Provider VDC's automatically-created VXLAN network pool should be used. NetworkPoolReference must be empty if this element appears in the request. CpuAllocationMhz long No none 5.7 CPU allocation in Mhz CpuAllocationMhz long No none 5.7 CPU allocation in Mhz CpuGuaranteedPercentage long No always 5.7 Percentage of allocated CPU resources guaranteed to vApps deployed in this vDC. For example, if this value is 75, then 75% of allocated resources are guaranteed. Required when AllocationModel is AllocationVApp or AllocationPool. Value defaults to 100 if the element is empty. CpuGuaranteedPercentage long No always 5.7 Percentage of allocated CPU resources guaranteed to vApps deployed in this vDC. For example, if this value is 75, then 75% of allocated resources are guaranteed. Required when AllocationModel is AllocationVApp or AllocationPool. Value defaults to 100 if the element is empty. CpuLimitMhz long No none 35.2 CPU limit in Mhz CpuLimitMhz long No none 35.2 CPU limit in Mhz CpuLimitMhzPerVcpu long No none 5.7 vCPU speed in Mhz CpuLimitMhzPerVcpu long No none 5.7 vCPU speed in Mhz FastProvisioningEnabled boolean No always 5.7 Boolean to request fast provisioning. Request will be honored only if the underlying datastore supports it. Fast provisioning can reduce the time it takes to create virtual machines by using vSphere linked clones. If you disable fast provisioning, all provisioning operations will result in full clones. GatewayConfiguration VdcTemplateSpecificationGatewayConfigurationType No always 5.7 Defines a gateway and NAT Routed organization VDC network to be created. IncludeMemoryOverhead boolean No always 35.0 Set to true to indicate if the FLEX vDC is to include memory overhead into its accounting for admission control. This field can only be set on input for FLEX vDC templates and Allocation VApp vDC templates. However, this field will be returned properly when read. IsElastic boolean No always 35.0 Set to true to indicate if the FLEX vDC is to be elastic. This field can only be set on input for FLEX vDC templates and Allocation VApp vDC templates. However, this field will be returned properly when read. MemoryAllocationMB long No none 5.7 Memory allocation in MB MemoryAllocationMB long No none 5.7 Memory allocation in MB MemoryGuaranteedPercentage long No always 5.7 Percentage of allocated memory resources guaranteed to vApps deployed in this vDC. For example, if this value is 75, then 75% of allocated resources are guaranteed. Required when AllocationModel is AllocationVApp or AllocationPool. Value defaults to 100 if the element is empty. MemoryGuaranteedPercentage long No always 5.7 Percentage of allocated memory resources guaranteed to vApps deployed in this vDC. For example, if this value is 75, then 75% of allocated resources are guaranteed. Required when AllocationModel is AllocationVApp or AllocationPool. Value defaults to 100 if the element is empty. MemoryLimitMb long No none 35.2 Memory limit in Mb MemoryLimitMb long No none 35.2 Memory limit in Mb NetworkPoolReference ReferenceType No always 5.7 Reference to a network pool in the Provider VDC. Must be empty if you specify AutomaticNetworkPoolReference. NetworkProfileConfiguration VdcTemplateNetworkProfileType No 35.0 NicQuota int Yes always 5.7 Maximum number of virtual NICs allowed in this vDC. Defaults to 0, which specifies an unlimited number. ProvisionedNetworkQuota int Yes always 5.7 Maximum number of network objects that can be deployed in this VDC. Defaults to 0, which means no networks can be deployed. StorageProfile VdcStorageProfileType Yes always 5.7 A set of name of Storage Profiles, with corresponding limit value, that all Provider VDCs must have, and that are selected at the time of VDC Template instantiation. ThinProvision boolean No always 5.7 Boolean to request thin provisioning. Request will be honored only if the underlying datastore supports it. Thin provisioning saves storage space by committing it on demand. This allows over-allocation of storage. VmQuota int No always 5.7 The quota of VMs that can be created in this vDC. Includes VMs in both vApps and vApp templates, deployed, or otherwise. Defaults to 0, which specifies an unlimited number.
