Storage Pool node

A Storage Pool node represents a block of storage from which storage volumes and other storage pools can be allocated. A storage system may expose one or more storage pools. Where there is a hierarchy of pools (Primordial -> Concrete), this is modeled using a Hierarchy relationship.

Creation/update

A Storage Pool node is created or updated when a storage pool is discovered as a result of:

WBEM queries to storage management software triggered by the creation or update of an SI representing storage management software
Directly discovered storage using WBEM queries to the WBEM/SMI-S provider triggered by the creation or update of a Storage Device node representing the chassis
Directly discovered storage using SNMP triggered by the creation or update of a Storage Device node representing the chassis

Removal

A Storage Pool node is removed when its parent Storage System node is removed. This is Containment Removal.

Storage Pool node attributes

The attributes of a Storage Pool node are as described in the following table:

UI Name Attribute Name and Type	Description
Not displayed in UI `key string`	Globally unique key.
Pool ID `pool_id string`	Id of the pool.
Type `pool_type string`	Type of the pool.
Name `name string`	Name of the pool.
RAID Level `raid_level string`	RAID level.
Capacity `capacity int`	Capacity in bytes.
Consumed Capacity `consumed_capacity int`	Amount of capacity that has actually been consumed by clients.
Subscribed Capacity `subscribed_capacity int`	Amount of capacity that has been assigned to clients.
Oversubscription Warning `oversubscription_warning boolean`	Indicates that the pool is over-subscribed and running low on capacity.
Remaining Capacity `remaining_capacity int`	Remaining capacity in bytes.
Total Raw Capacity `total_raw_capacity int`	Total raw capacity in bytes.
Remaining Raw Capacity `remaining_raw_capacity int`	Remaining raw capacity in bytes.
Virtual Capacity `virtual_capacity int`	Virtual capacity in bytes.
Real Capacity `real_capacity int`	Real capacity in bytes.
Virtual `virtual : boolean`	Flag to indicate if this is virtual.
Configured Volume Capacity `configured_capacity int`	Amount of capacity that has been configured.

Storage Pool node relationships

The relationships of a Storage Pool node are as described in the following table:

UI name	Relationship	Description
Storage System	`StoragePool: ContainedPool: Containment: Container: StorageSystem`	StorageSystem for this Pool.
Storage Volumes	`StoragePool: Container: Containment: ContainedVolume: StorageVolume`	Volumes from this Pool.
Parent Pool	`StoragePool: Child: Hierarchy: Parent: StoragePool`	Storage Pools of which this one is a part.
Subsidiary Pools	`StoragePool: Parent: Hierarchy: Child: StoragePool`	Storage Pools allocated from this one.
Storage Volume Mirrors	`StoragePool: Container: Containment: ContainedVolume: StorageVolumeMirror`	Volume Mirrors from this Pool.

Storage Pool node expressions

The expressions of a Storage Pool node are as described in the following table:

Name	Expression	Description
Configured Volume Capacity	`configured_capacity_display : formatQuantity(configured_capacity, "B1024")`	Configured capacity.
