Capacity Manager > Thin Provisioning Capacity & Utilization > Hitachi DP Pool Summary

The Dynamic Provisioning Pool uses virtual volumes for data storage, with actual capacity available upon request to a host writing to LUN storage. Use this report to ensure that your pool always has sufficient free capacity, enabling on-demand provisioning to hosts.

Table: Hitachi Dynamic Provisioning Pool Summary

Column name	Description
Pool Capacity
Pool ID	The name of the Dynamic Provisioning Pool.
Storage Array	The storage array on which the pool resides.
Used%	Mouse over the thermometer to view the percentage of the pool that is used. Used capacity is the total capacity of all the pages that have data written to them; that is, consumed or touched storage. The percentage is the used size divided by the total physical capacity.
# of DP Pool VOLs	Number of Hitachi journal pool volumes. For AMS (AMS200/500/1000) and WMS arrays: This is the number of the QuickShadow volumes. For AMS (AMS2010/2100/2300/2500, MSS) arrays: If the pool function is 3, then this is the number of the QuickShadow volumes or TrueCopyAsync volumes. For USP arrays: If the pool function is 3, then this is the number of QuickShadow volumes. If the pool function is 4, then this is the number of the Universal Replicator Journal volumes (for Open Volume). For USP_V arrays: If the pool function is 3, this is the number of the QuickShadow volumes. If the pool function is 4, this is the number of the Universal Replicator Journal volumes (for Open Volume). If the pool function is 5, this is the number of the Hitachi Dynamic Provisioning Pool (HDP) volumes. For VSP arrays: If the pool function is 3, then this is the number of the QuickShadow volumes. If the pool function is 4, this is the number of the Universal Replicator volumes. If the pool function is 5, this is the number of the HDP/HDT volumes.
# Array Groups	Number of Array Groups. Links to List Array Groups report.
Capacity of DP Pool	Virtual volumes can have a capacity that is greater than the pool capacity; however, it is imperative that you monitor the pool capacity to ensure that space is available on demand.
Consumed	This is consumed or touched capacity; that is, the sum of the 42 MB pages assigned from the pool that have data written to them.
Free In Pool	Capacity - Used Size = Available Size. Monitor this space to ensure that you do not deplete the available space in a pool, ensuring that host requests for storage are not denied
Physical Capacity
Total	Physical capacity of pool (KB). This item is output when the value of poolFunction is 5 and the storage system is VSP G1000 (with a microcode version of 80-04-0X-XX/XX or later), VSP Gx00 models (with a microcode version of 83-03-0X-XX/XX or later), or VSP Fx00 models (with a microcode version of 83-03-0XXX/XX or later).
Used	Physical capacity usage of the pool (KB). This item is output when the value of poolFunction is 5 and the storage system is VSP G1000 (with a microcode version of 80-04-0X-XX/XX or later), VSP Gx00 models (with a microcode version of 83-03-0X-XX/XX or later), or VSP Fx00 models (with a microcode version of 83-03-0XXX/XX or later).
Used %	The percentage is the used size divided by the total physical capacity.
Physical FMC Pool Volumes
Total	Total physical capacity of the pool volume whose drive type is FMC (KB). This item is output when the value of poolFunction is 5 and the storage system is VSP G1000 (with a microcode version of 80-04-0X-XX/XX or later), VSP Gx00 models (with a microcode version of 83-03-0X-XX/XX or later), or VSP Fx00 models (with a microcode version of 83-03-0XXX/XX or later).
Used	Total physical capacity usage of the pool volume whose drive type is FMC (KB). This item is output when the value of poolFunction is 5 and the storage system is VSP G1000 (with a microcode version of 80-04-0X-XX/XX or later), VSP Gx00 models (with a microcode version of 83-03-0X-XX/XX or later), or VSP Fx00 models (with a microcode version of 83-03-0XXX/XX or later).
FMC Pool Volume Capacity
Total	Total capacity of the pool volume whose drive type is FMC (KB). This item is output when the value of poolFunction is 5 and the storage system is VSP G1000 (with a microcode version of 80-04-0X-XX/XX or later), VSP Gx00 models (with a microcode version of 83-03-0X-XX/XX or later), or VSP Fx00 models (with a microcode version of 83-03-0XXX/XX or later).
Used	Total capacity usage of the pool volume whose drive type is FMC (KB). This item is output when the value of poolFunction is 5 and the storage system is VSP G1000 (with a microcode version of 80-04-0X-XX/XX or later), VSP Gx00 models (with a microcode version of 83-03-0X-XX/XX or later), or VSP Fx00 models (with a microcode version of 83-03-0XXX/XX or later).
Saving	Saved Capacity for FMC (KB).
Virtual
# of DP VOLs	The number of virtual volumes in this Dynamic Provisioning pool; links to the LUN Utilization Summary. This is capacity that is available to be allocated to hosts; associated capacity.
Capacity of DP VOLs	This is the capacity of all DP Volumes that have been allocated to hosts. It also includes overhead for dynamic provisioning. This capacity could be over-subscribed, which means that the capacity shown here could exceed the capacity shown in the Capacity column.
Overprovision	Percentage = Capacity of DP Vols/Capacity of DP Pool
Allocated	Allocated Capacity (KB).
Threshold1	Journal Pool threshold used to monitor consumed capacity.
Threshold2	This threshold is hard-coded in the firmware of the array.
Status	Reported by Device Manager: Normal, Blocked, Over Threshold
