Description

A CompositeExtent is used to model the distribution of user data across one or more underlying StorageExtents, which may or not be protected by some redundancy mechanism. CompositeExtents represent a contiguous range of logical blocks. CompositeExtents may overlap, however, the underlying StorageExtents within the overlap shall not contain any check data. Distribution of check data may be specified using the CompositeExtentBasedOn association.

Properties

IdTypeRangeDescription
Key
CreationClassName string
Max Length256
CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.
DeviceID string
Max Length64
An address or other identifying information used to uniquely name the LogicalDevice.
SystemCreationClassName string
Max Length256
The CreationClassName of the scoping system.
SystemName string
Max Length256
The System Name of the scoping system.
Read Only
ExtentInterleaveDepth uint64
Number of StorageExtents to stripe as a collective set. In SCC, this value is defined as the number of stripes to count before continuing to map into the next contiguous set of Extents, beyond the current stripe.
ExtentStripeLength uint64
Number of contiguous underlying StorageExtents counted before looping back to the first underlying StorageExtent of the current stripe. It is the number of StorageExtentsforming the user data stripe.
IsConcatenated boolean
True indicates that the data is concatenated across the various StorageExtents in the Group.
NumberOfBlocks uint64
