When you add a host to an EVC-enabled cluster, the vCenter Server determines the CPU compatibility to preserve vMotion compatibility within the cluster. If the host CPU is compatible with those already in the cluster, the Server adds the host to the cluster and configures it for compatible operation. Hosts that are not compatible are not allowed to join the cluster.
The inherited key property is a string value that uniquely identifies an EVC mode. The vCenter Server assigns the key value; the vSphere API uses the key to identify modes in summary and information objects:
The inherited label and summary properties are human-readable strings.
You can use the track and vendorTier properties to determine feature-superset relationships between modes without examining the individual feature bits in guaranteedCPUFeatures. The CPU feature baseline of mode A is a superset of mode B's baseline if and only if:
Properties
| Name | Type | Description |
|---|---|---|
| featureCapability* | HostFeatureCapability[] |
Describes the feature capability baseline associated with the EVC mode.
On the cluster where a particular EVC mode is configured,
these features capabilities are guaranteed, either because the host
hardware naturally matches those features or because feature masks
are used to mask out differences and enforce a match.
Since vSphere API 5.1 |
| featureMask* | HostFeatureMask[] |
The masks (modifications to a host's feature capabilities) that limit a
host's capabilities to that of the EVC mode baseline.
Since vSphere API 5.1 |
| featureRequirement* | VirtualMachineFeatureRequirement[] |
The conditions that must be true of a host's feature capabilities in order
for the host to meet the minimum requirements of the EVC mode baseline.
Since vSphere API 5.1 |
| guaranteedCPUFeatures* | HostCpuIdInfo[] |
Describes the CPU feature baseline associated with the EVC mode.
On the cluster where a particular EVC mode is configured,
those CPU features are guaranteed, either because the host
hardware naturally matches those features or because CPU feature override
is used to mask out differences and enforce a match.
Since vSphere API 4.1 |
| track | xsd:string[] |
Identifiers for feature groups that are at least partially present in
the guaranteedCPUFeatures array for this mode.
Use this property to compare track values from two modes.
Do not use this property to determine the presence or absence of
specific features.
Since vSphere API 4.1 |
| vendor | xsd:string |
CPU hardware vendor required for this mode.
|
| vendorTier | xsd:int |
Index for ordering the set of modes that apply to a given CPU vendor.
Use this property to compare vendor tier values from two modes.
Do not use this property to determine the presence or absence
of specific features.
