Version 4.1.00

Performing Common Operations

Customizing the Oversubscription Risk IndicatorThe Oversubscription Risk metric, available in the Storage Pools view, indicates whenoversubscribed thin-pools will soon not be able to allocate additional space to a volume whenrequested by the subscriber host. By default, this metric displays:

No risk when the Storage Consumed Capacity Percentage metric is lower than 75% andthe number of days before saturation is greater than 30 days .

Warning when the Storage Consumed Capacity Percentage metric is greater than or equalto 75% and the number of days before saturation is greater than or equal to 7.

Critical when the Storage Consumed Capacity Percentage metric is greater than or equalto 75% and the number of days before saturation is less than 7.

This behavior can however be modified to warn administrators sooner about an oversubscription riskby customizing the oversubscription risk indicator.

To customize the oversubscription risk indicator:1. In the BMC TrueSight Capacity Optimization console, select the Views tab.

Version 4.1.00

Storage Capacity Views and Reports for BMC TrueSight Capacity Optimization leveragesBMC TrueSight Capacity Optimization capabilities to automatically analyze, forecast, and optimizeperformance and storage capacity in your IT environment. The following use cases provide somebasic management operations that can be easily performed with Storage Capacity Views andReports for BMC TrueSight Capacity Optimization:

better allocate storage capacity to new servers

analyze storage capacity utilization

keep an eye on over-subscribed thin pools

plan for additional storage capacity

reclaim unused storage capacity

report the capacity consumed per host.

50Allocating Storage Capacity to New Servers


Version 4.1.00

Allocating Storage Capacity to NewServersAllocating storage capacity to new servers consists in identifying which storage pool from whichstorage system is best suited to host the storage capacity required. To identify these storage pools,administrators need to:

list the storage systems that can meet allocation requirements

verify the storage systems bandwidth

choose the most relevant storage pool

verify the protection level.

Listing the Storage Systems that Meet AllocationRequirements1. In the BMC TrueSight Capacity Optimization console, select the Views tab.


3. List the storage systems that meet your allocation requirements. You can for example apply afilter on the Available Capacity column to only display the storage systems for which morethan 5000 GB are available:

In the Available Capacity column, click .

From the operator pull-down list, select >.

Type 5000.

From the pull-down list, select GB.

Press the Enter key.

Once the storage systems matching your search criteria have been displayed, you can verify thestorage systems’ bandwidth and the number of ports available.



Version 4.1.00

Verifying the Storage Systems Bandwidth

Verifying the storage systems bandwidth is an essential step that will help administrators choose thestorage system that better meets their allocation requirements. To perform this operation,administrators must check the bandwidth utilization and the number of ports available for eachstorage system.



3. Show the Number of Ports column:

Click and select Show/hide columns.

Check the Number of Ports box.

Click Apply.

4. Verify the bandwidth utilization of each storage system. If the value is:

low, the storage system can be used to allocate storage capacity to new servers

high, check the number of ports currently available to know if additional ports can be added.

The most relevant storage system is now identified. You can now proceed to the next step, i.echoosing a storage pool according to its pool type, its available capacity, and the oversubscriptionrisk.



Version 4.1.00

Choosing the Most Relevant Storage Pool 1. In the BMC TrueSight Capacity Optimization console, select the Views tab.


3. Select the Storage Pools tab.

4. Apply a filter to the Pool Type column:

In the Pool Type column, click .

From the operator pull-down list, select like

Enter the Pool Type of your choice. You can for example enter DP Pool for Hitachi VSP,Parity Group for Hitachi AMS and Hitachi HUS, Thin pool or RAID Group for EMC, andDisk Folder for Dell Compellent.

5. Check the Available Capacity of the different storage pools displayed and theOversubscription Risk. If there is no risk of oversubscription and if the available capacity issufficient to meet your allocation requirements, you can choose this storage pool.

A list of potential storage pools is now available. You can verify the protection level of each storagepool to choose the one that better suits your needs.



Version 4.1.00

Verifying the Protection Level

The protection level can be viewed with the Storage Capacity Views at the storage pools or at thevolumes levels.

To verify the protection level:



3. To verify the protection level at the storage pools level:

Select the Storage Pools tab.

Click the pool of your choice to display its detail.

Check the Pool Protection Level metric.



Version 4.1.00

4. To verify the protection level at the volumes level:

Select the Volumes tab.

Click the volume of your choice to display its detail.

Check the Volume RAID Level metric.

Once this last step is performed, you should know which storage pool from which storage system isbest suited to host the storage capacity required. If no storage pools meet your requirement, you willthen have to create a new one.

55Analyzing Storage Capacity Utilization


Version 4.1.00

Analyzing Storage CapacityUtilizationStorage demand exponentially grew over the past years and lead to runaway storage costs. Tocontrol these costs, SAN administrators are asked to better plan for future capacity needs, which isalmost impossible without a clear view of the storage capacity utilization. With Storage CapacityViews and Reports for BMC TrueSight Capacity Optimization, administrators can analyze storagecapacity utilization at the storage systems and storage pools levels.

At the Storage Systems Level1. In the BMC TrueSight Capacity Optimization console, select the Views tab.


4. In the Storage Systems tab, verify the capacity of the storage systems and more specifically:

their overall size (Size metric).

their total space (Capacity metric).

the host visible capacity (Subscribed Capacity metric).

the total space not consumed (Available Capacity metric).

the space actually consumed (Consumed Capacity metric).



Version 4.1.00

5. Click the storage system for which you wish to get more information.



Version 4.1.00

6. In the graph pane, click to analyze the trend of your storage system utilization.

7. You can also export this data to Excel for further analysis by first clicking and then .

Based on the capacity information available, you can now plan for your current and future capacityneeds.



Version 4.1.00

At the Storage Pools Level1. In the BMC TrueSight Capacity Optimization console, select the Views tab.


3. Select the Storage Pools tab to display the Storage Pools Overview.

4. If needed, select from the pull-down list the storage system for which you wish to study thestorage pools.

5. Verify the capacity of your storage pools and more especially:

their overall size (Size metric).


the host visible capacity (Subscribed Capacity metric).





Version 4.1.00

8. Click the storage pool for which you wish to get more information.

9. In the graph pane, click to analyze the trend of your storage pool utilization.

10. You can also export this data to Excel for further analysis by first clicking and then .

This capacity information will help you better control your storage costs.

60Identifying Oversubscription Risks


Version 4.1.00

Identifying Oversubscription Risks

An oversubscription situation is automatically identified when:

1. the storage pool is configured for thin provisioning (“thin storage pool”)

2. the storage pool is oversubscribed, i.e. the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3. the storage pool actual consumed capacity has crossed the configured threshold (refer to thesection Customizing the Oversubscription Risk Indicator).

Such situation is highly critical because the inability to allocate additional space to a volume whenrequested by the subscriber host will lead to catastrophic data loss and corruption.

To make sure no oversubscription situation is about to occur, administrators can check the Oversubscription Risk column available in the Storage Capacity View. By default, this metricdisplays:

No risk when the Storage Consumed Capacity Percentage metric is lower than 75% andthe number of days before saturation is greater than 30 days .

Warning when the Storage Consumed Capacity Percentage metric is greater than or equalto 75% and the number of days before saturation is greater than or equal to 7.

Critical when the Storage Consumed Capacity Percentage metric is greater than or equalto 75% and the number of days before saturation is less than 7.

The threshold of the Storage Consumed Capacity Percentage metric can however be modifiedfor each storage pool to warn administrators sooner about an oversubscription risk (Refer to thesection Customizing the Oversubscription Risk Indicator).

To Identify Oversubscription Situations1. In the BMC TrueSight Capacity Optimization console, select the Views tab.


61Identifying Oversubscription Risks


Version 4.1.00

3. Select the Storage Pools tab.


5. Apply a filter to the Pool Type column to only display thin pools:

In the Pool Type column, click .

From the operator pull-down list, select like.

Type Thin Pool.


5. Identify the thin-pools that will soon not be able to allocate additional space to a volume:

In the Oversubscription Risk column, click .


Type Critical to list thin-pools that will saturate in less than 7 days.


You now have all the information required to prevent oversubscription situations and unrecoverabledata loss and corruption.

62Planning for Additional Storage Capacity


Version 4.1.00

Planning for Additional StorageCapacityAdministrators are not only asked to assign storage resources but also to plan for both current andfuture storage requirements. Because under-purchasing and over-purchasing capacity willrespectively result in downtimes and wasted storage, both situations must be prevented. Smoothlystorage administration can only be achieved if administrators know exactly:

when their storage pools will be running out of capacity

by how much the capacity of their storage pools must be extended to meet allocationrequirements

if there are enough unused disks in the storage systems to extend the capacity of the existingstorage pools.

With this information, they will be able to guarantee enough remaining space to answer allocationrequests as quickly as possible.

When will Storage Pools be running out of Capacity?1. In the BMC TrueSight Capacity Optimization console, select the Views tab.





Version 4.1.00


5. Verify the capacity of your storage pools and more especially:




5. Identify which storage pools are at a risk of being saturated:

In the Saturation Risk column, click .


Type saturation


You will now be able to take the necessary actions at the right time to ensure that storage pools willnever run out of capacity.

By how much does the Capacity of the Storage PoolNeed to be Extended? 1. In the BMC TrueSight Capacity Optimization console, select the Views tab.





Version 4.1.00

4. Click the storage pool of your choice to display its details and check its Consumed CapacityTrendline.

After completing the above steps, you should know exactly by how much the capacity of your storagepool needs to be extended.



Version 4.1.00

Are There Enough Unused Disks in the StorageSystems?

Before purchasing additional space, administrators can also check if there are unused disks in theirstorage systems that could still be used to extend the capacity of the existing storage pools. Toperform this verification:



3. Click the storage system for which you wish to check the number of unused disks.

4. Check the Available for Storage Pools metric.

You now know which disks can be used to extend the capacity of your storage pools.

66Reclaiming Unused Storage Capacity


Version 4.1.00

Reclaiming Unused StorageCapacityOver time, as servers connected to a SAN get decommissioned, administrators find an increasingnumber of unmapped volumes that are no longer used by any server. These volumes, while unused,still occupy disk space in the storage system. Being able to identify such unmapped volumes andreclaim the disk space uselessly consumed by these volumes will help administrators avoidunnecessary upgrades and extensions of their storage systems.

Identifying Unmapped Volumes1. In the BMC TrueSight Capacity Optimization console, select the Views tab.


3. Select the Volumes tab.


5. Apply a filter to the Mapped column to only display the unmapped volumes:

In the Mapped column, click .


Type Not Mapped.



Version 4.1.00


The list of unmapped volumes is displayed:

Volumes might be tagged as Not Mapped but be required for the correct operation of the system.

You can now reclaim the disk space uselessly consumed by these volumes to avoid unnecessaryupgrades and extensions.

Identifying Unused Volumes1. In the BMC TrueSight Capacity Optimization console, select the Views tab.




Version 4.1.00

3. Select the Volumes tab.


5. Apply a filter to the Time Since Last Activity (Days) column:

In the Time Since Last Activity (Days) column, click .

From the operator pull-down list, select =.

Type the number of days required (e.g.: 30).


The list of volumes that have not been used for 30 days is displayed. You can now take thenecessary actions and reclaim the unused space.

The Time Since Last Activity parameter is evaluated from the date the ETL was initially started.

69Reporting the Capacity Consumed per Host


Version 4.1.00

Reporting the Capacity Consumedper HostBecause hosts are not always well-identified, determining the capacity consumed per host is not aneasy task. Administrators must not only find out what are the physical hosts but also verify thecapacity that was initially allocated and finally determine the capacity that is actually consumed byeach host. All these operations can be performed with Storage Capacity View.

The capacity consumed by the virtual machines cannot be represented by Storage Capacity Views andReports for BMC TrueSight Capacity Optimization since the datastores' logical assembly is not visible.

Reporting the Capacity Consumed Per Host

To determine the capacity actually consumed per host:



3. Open the Reconciled Host Mapping tab and click Hosts.

4. Identify the host to which storage has been allocated (Host metric).

5. Verify the capacity exposed to this host (Host Visible Capacity metric).

6. Verify the capacity actually consumed per host (Consumed Capacity metric).

The capacity consumed per host is now clearly identified. It could now be interesting to determinefrom which storage system or which storage pool this capacity has been allocated.



Version 4.1.00

Determining Storage Capacity Allocation Source

Determining the capacity actually consumed per host is not always sufficient to manage storagecapacity needs. You may also need to know from which storage system or which storage pool thiscapacity has been allocated.

To obtain this information from the Reconciled Host Mapping tab:



3. Open the Reconciled Host Mapping tab and click Hosts to Systems:

4. Apply a filter on the System Name column to only display the storage system of your choice:

In the System Name column, click .

From the operator pull-down list, select Like.

Type the storage system name (in our example VSP).


Verify the capacity exposed to the host for the storage system specified (Host Visible



Version 4.1.00

Capacity metric).

Verify the capacity actually consumed on the storage system specified (Consumed Capacitymetric).

5. To obtain additional information about a storage pool, click Hosts to Pool.

6. Apply a filter on the Pool Name column to only display the storage pool of your choice:

In the Pool Name column, click .

From the operator pull-down list, select Like.

Type the storage pool name (in our example ThinProvisioning).


Verify the capacity exposed to the host for the storage pool specified (Host Visible Capacitymetric).

Verify the capacity actually consumed on the storage pool specified (Consumed Capacitymetric).

7. You can also refer to the RAID Level and Service Level columns to respectively know thelevels of protection and service.

You now have all the information required to manage your storage capacity needs and cleverlyallocate resource.
