DynamicStoragePool is the same as the logical size of the volume; RAID overhead is accounted for in the DynamicStoragePool itself and does not carry over to the child volume. • BlockSize = 512 • TPD_StorageVolume.NumberOfBlocks = TPD_StorageVolume.ConsumableBlocks = (10240 * 1024 * 1024) / BlockSize = 20971520 (logical block size of the volume) • TPD_StorageVolume.NumberOfRawBlocks = (20480 * 1024 * 1024) / BlockSize = 41943040 (raw block size of the volume) • TPD_AllocatedFromStoragePool.SpaceConsumed between dynamic storage pool and volume = TPD_StorageVolume.NumberOfBlocks * BlockSize = 10737418240 • TPD_DynamicStoragePool.RemainingManagedSpace = TPD_DynamicStoragePool.SpaceLimit - volume logical size = 100G - 10G = 90G • TotalManagedSpace for the dynamic storage pool remains unchanged. Thinly Provisioned Storage Volume TPD_AllocatedFromStoragePool.SpaceConsumed between the parent dynamic storage pool and the thinly provisioned storage volume represents the actual size allocated to the volume. This value is also represented in StorageVolume.ProvisionedConsumableBlocks, i.e., SpaceConsumed equals ProvisionedConsumableBlocks. As is the case with Section (page 43), logical capacity is used in calculating SpaceConsumed with child volumes/delta replica pool. StorageVolume.NumberOfBlocks is the virtual size of the TPVV. TPD_StorageVolume.ConsumableBlocks is set to be the same as TPD_StorageVolume.NumberOfBlocks. Example: • Initial State A dynamic storage pool has a virtual capacity of 100GB (as set in the -sdgl option). This value is reflected in TPD_DynamicStoragePool.SpaceLimit property and is what is available for volume allocation. Let us assume that there are no volumes or DeltaReplicaStoragePool allocated from this pool initially. The TotalManagedSpace property reflects the actual capacity allocated to the pool. • Before Volume Creation • TPD_DynamicStoragePool.TotalManagedSpace = actual capacity allocated to the pool • TPD_DynamicStoragePool.SpaceLimit = 100GB • TPD_DynamicStoragePool.RemainingManagedSpace = 100 GB (capacity that can be used to create volume) • After Volume Creation Suppose a RAID-10 volume of logical size 10G is created from the dynamic storage pool. This value is represented in the TPD_StorageVolume class as NumberOfBlocks (ConsumableBlocks also has the same value). Since this is a thinly provisioned volume, what are actually allocated to the volume may not be the full 10G (let us assume it is 4G). The actual allocated value is represented in the TPD_StorageVolume class as ProvisionedConsumableBlocks. AllocatedFromStoragePool.SpaceConsumed between StorageVolume and the parent DynamicStoragePool is the capacity that is actually allocated 44 CIM API SMI-S Support

DynamicStoragePool

is the same as the logical size of the volume; RAID overhead is accounted

for in the

DynamicStoragePool

itself and does not carry over to the child volume.

•

•

TPD_StorageVolume.NumberOfBlocks

TPD_StorageVolume.ConsumableBlocks

= (10240 * 1024 * 1024) /

BlockSize

= 20971520 (logical block size of the volume)

•

TPD_DynamicStoragePool.RemainingManagedSpace

TPD_DynamicStoragePool.SpaceLimit

•

TotalManagedSpace

Thinly Provisioned Storage Volume

TPD_AllocatedFromStoragePool.SpaceConsumed

between the parent dynamic storage

pool and the thinly provisioned storage volume represents the actual size allocated to the volume.

This value is also represented in

StorageVolume.ProvisionedConsumableBlocks

, i.e.,

SpaceConsumed

equals

ProvisionedConsumableBlocks

As is the case with

Section (page 43)

, logical capacity is used in calculating

SpaceConsumed

with child volumes/delta replica pool.

StorageVolume.NumberOfBlocks

is the virtual size of the TPVV.

TPD_StorageVolume.ConsumableBlocks

is set to be the same as

TPD_StorageVolume.NumberOfBlocks

Example:

•

Initial State

A dynamic storage pool has a virtual capacity of 100GB (as set in the –sdgl option). This value

is reflected in

TPD_DynamicStoragePool.SpaceLimit

property and is what is available for

volume allocation. Let us assume that there are no volumes or

DeltaReplicaStoragePool

allocated from this pool initially. The

TotalManagedSpace

property reflects the actual capacity

allocated to the pool.

•

Before Volume Creation

•

TPD_DynamicStoragePool.TotalManagedSpace

= actual capacity allocated to the

pool

•

TPD_DynamicStoragePool.SpaceLimit

= 100GB

•

TPD_DynamicStoragePool.RemainingManagedSpace

= 100 GB (capacity that can

be used to create volume)

•

After Volume Creation

Suppose a RAID-10 volume of logical size 10G is created from the dynamic storage pool. This

value is represented in the

TPD_StorageVolume

class as

NumberOfBlocks

(

ConsumableBlocks

also has the same value). Since this is a thinly provisioned volume, what

are actually allocated to the volume may not be the full 10G (let us assume it is 4G). The actual

allocated value is represented in the

TPD_StorageVolume

class as

ProvisionedConsumableBlocks

AllocatedFromStoragePool.SpaceConsumed

between

StorageVolume

and the parent

DynamicStoragePool

is the capacity that is actually allocated
