Configuring Storage Optimization Rules
APTARE StorageConsole provides a set of storage optimization rules to assess areas within your enterprise that offer candidates for optimization. These rules include parameters that can be configured to isolate specific conditions relevant for your environment. For example, the Unallocated LUNs rule can be configured to exclude LUNs less than a certain size. While various use cases drive how you configure a rule, the goal is to have analytics that help you identify storage optimization candidates and trends that require attention. This on-going process should periodically assess trends and codify business practices. See Storage Optimization Solution Overview, Enabling Storage Optimization Rules, and Storage Optimization Solution Reports.
Once configured, a scheduled process gathers historical data for these categories so that you can identify areas that require further scrutiny. Accompanying reports present data that can be monitored over time, enabling an actionable process to maintain an optimized storage environment.
Best Practice
When configuring values for parameters, be as liberal as possible, initially. Then, over time, change parameters to produce a narrower actionable list. For optimal data comparisons, avoid frequent parameter modifications.
To edit a storage optimization rule
If optimization rules are not modified, the historical data process uses an active rule’s default settings to collect the historical data.
1. Select Admin > Solutions > Storage Optimization.
 
Rule
Rules are listed within relevant categories, such as Cloud and Storage.
Availability
If a particular type of collection is not licensed or collected, storage optimization data will not be available, regardless of how a rule is configured. In some cases, a Portal may have the necessary license, but collection may not have been enabled and/or completed.
• Cloud does not require a specific license in order to deploy a data collector.
• Data Protection requires a Backup Manager license.
• File Analytics requires a File Analytics license.
• Storage requires a Capacity Manager license.
• Virtualization requires a Virtualization Manager license.
Description
The full description of the Storage Optimization rule can be viewed by placing your mouse over the description.
Notes
Enter operational notes for future reference.
Status
• Green indicates successful collection of storage optimization historical data for enabled rules.
• Red indicates failed historical data collection. It could be that collection is attempting to access data for a product module that is not in your Portal environment. Click the red icon to view the Database Error Aggregation report.
• A non-colored icon indicates that the storage optimization process did not run, typically because the rule is not enabled.
State
Indicates if the rule is Enabled or Disabled.
Last Run
The date and time that the Storage Optimization process ran and evaluated the collected data against the rule’s configured parameters.
2. Select a rule in the Storage Optimization grid and click Edit. Or, simply double-click the rule to access the edit dialog. See also, Storage Optimization Rule Prerequisites and Logic.
Storage Optimization Rule
Description
Cloud Rules
AWS Orphan Snapshots
Amazon Web Services orphaned snapshots that are consuming storage may be impacting costs. This rule identifies snapshots for EC2 instances that no longer exist. For actionable information, see the Storage Optimization detail reports.
AWS Orphan Volumes
Amazon Web Services orphaned volumes that are consuming storage may be impacting costs. This rule identifies volumes for EC2 instances that no longer exist. For actionable information, see the Storage Optimization reports.
Data Protection Rules
Data Domain File Compression
Compression metrics for the last 30 days are evaluated for inefficient storage usage and compression ratios for Data Domain clients. A low compression ratio may indicate a storage optimization opportunity or it may warrant a move of low compression clients to less expensive storage. For additional details, see the Data Domain NetBackup File Compression Summary report.
High Backup Retention Jobs
Backups that are retained for too many days may be wasting storage and increasing maintenance costs.
File Analytics Rules
File Type Usage
File types that are consuming storage can be reviewed. The filename extension identifies a file type, such as iso, log, and cab. This File Type rule is relevant only if File Analytics data collection is enabled. For a list of file types that are relevant for your environment, see the File Types report.
Inactive Large Files
Large files consuming storage can be considered when making tiered storage migration decisions. This rule is relevant only if File Analytics data collection is enabled. For additional details, see the Largest Files report.
Storage Rules
Inactive LUNs
LUNs that have no I/O activity collected in the last 30 days, or the collected value during that time period is zero, are candidates for storage reclamation.
This rule explicitly examines 30 days of collected LUN performance data. This rule can filter the data by RAID type. The format for RAID type specification is specific to storage vendors. For a list of RAID types in your environment, run the LUN Utilization Summary report. See also, Storage Rules and Logic.
Overprovisioned Hosts
File system usage can help identify overprovisioned file systems and hosts. For additional information, run the Host Utilization Summary report and the Host Filesystem Reclamation Candidates cloud report. See also, Storage Rules and Logic.
Unallocated LUNs
Storage associated with LUNs that have not been allocated to hosts can be considered for storage optimization.
This rule can filter the data by RAID type. The format for RAID type specification is specific to storage vendors. For a list of RAID types in your environment, run the LUN Utilization Summary or the Unallocated LUNs report. In addition, the Reclamation Summary report can reveal potential reclamation categories. See also, Storage Rules and Logic.
Undiscovered LUNs
LUNs that have been assigned to a host, but have not been discovered and therefore are not seen on the host side, indicate a reclamation opportunity. The storage in these orphaned LUNs is not available for mounting file systems.
This rule can filter the data by RAID type. The format for RAID type specification is specific to storage vendors. For a list of RAID types in your environment, run the LUN Utilization Summary report. In addition, the Reclamation Summary report illustrates potential reclamation categories. See also, Storage Rules and Logic.
Unused LUNs
Unused LUNs could be considered for reclamation. These are LUNs that have been assigned to a host, but the host has not been placed into a volume group, or a partition has not been created.
This rule can filter the data by RAID type. The format for RAID type specification is specific to storage vendors. For a list of RAID types in your environment, run the LUN Utilization Summary report. In addition, the Reclamation Summary report illustrates potential reclamation categories. See also, Storage Rules and Logic.
Virtualization Rules
Non-VM Files
VM storage that is being consumed by files that are unknown VM file types can be considered for storage optimization. For additional details, see the Datastore Usage Breakdown and the VM Files Summary reports. See also, Virtualization Rules and Logic.
VMs Aged Snapshots
VM snapshots have storage associated with them, but these snapshots have been forgotten for some time. Aged snapshots present a reclamation opportunity. For additional details, see the VM Snapshot Summary. See also, Virtualization Rules and Logic.
VMs Low CPU
VMs where the average CPU utilization is low for last 24 hours and CPU usage is less than 5%, may provide a storage optimization opportunity.
Filter your actionable list by guest size and guest state, for example, including only running large guests. For additional details, see the VM Summary report. See also, Virtualization Rules and Logic.
VMs Not in VM Inventory
VMs that are not in the VM inventory may be consuming storage. When a VM is removed from the inventory, it doesn’t necessarily mean that the associated storage is returned to the storage pool. For additional details, see the Datastore Usage Breakdown and the VM Files Summary reports. See also, Virtualization Rules and Logic.
VMs Powered Off
VMs that have been powered off may have storage associated with them. For additional details, see the VM Summary report. See also, Virtualization Rules and Logic.
VMs Undiscovered Disks
VMs that have been provisioned storage, but that storage is not being used by the VMs, may indicate a storage optimization opportunity. For additional details, see the Physical Disk Utilization report. See also, Virtualization Rules and Logic.
3. Click in a parameter field to view the green help text at the bottom of the dialog and then use those details to configure parameters. Each rule includes parameters unique to the data that is being evaluated. See also, Edit Storage Optimization Rule Example and Common Storage Optimization Parameters.
Edit Storage Optimization Rule Example
Because each Storage Optimization rule has its own set of parameters, rely on the green help text in the Edit dialog to guide your configuration.
The following example illustrates the types of parameters that can be adjusted to glean an actionable list from collected data. See also, Common Storage Optimization Parameters.
Common Storage Optimization Parameters
The parameters shown in the following list represent parameters that are common to multiple storage optimization rules. This list, however, does not represent a comprehensive list of storage optimization parameters. Refer to the green help text in each rule for parameter specifics.
