Term Description
Overcommitted space Storage space allotted to a thin-provisioned volume over and above the actually available physical
capacity of the NAS pool. The amount of overcommitted space for a NAS volume is: (Total volume
space) – (NAS pool capacity).
With thin provisioning, storage space is consumed only when data is physically written to the NAS
volume, not when the NAS volume is initially allocated. More storage space can be allocated to the
NAS volumes than has been allocated in the NAS pool itself.
Snapshot space Storage space occupied by snapshots of a NAS volume.
Data reduction saving Storage space reclaimed as a result of data reduction processing.
Managing the Storage Prole for a NAS Cluster or Pool
Storage Center Storage Proles control how Storage Center manages volume data. The selected Storage Prole dictates which
storage tier accepts initial writes, as well as how data progression moves pages between storage tiers to balance performance and
cost.
For more information about Storage Proles, see the Storage Manager Administrator’s Guide.
View the Storage Prole for the NAS Cluster or Pool
View the Storage Center Storage Proles congured for the NAS cluster or pool. A unique Storage Prole can be congured for
each Storage Center providing storage for the FluidFS cluster.
1. Click the Storage view and select a FluidFS cluster.
2. Click the Summary tab.
3. In the right pane, click Edit FluidFS Cluster Settings. The Edit FluidFS Cluster Settings dialog box appears.
4. Click the SC Storage Prole tab. For each Storage Center, the Storage Prole is displayed in the right pane in the Storage
Prole drop-down menu.
Change the Storage Prole for the NAS Cluster or Pool
Change the Storage Center Storage Proles congured for the NAS cluster or pool. A unique Storage Prole can be congured for
each Storage Center providing storage for the FluidFS cluster.
1. Click the Storage view and select a FluidFS cluster.
2. Click the Summary tab.
3. In the right pane, click Edit FluidFS Cluster Settings. The Edit FluidFS Cluster Settings dialog box appears.
4. Click the SC Storage Prole tab.
5. Locate the Storage Center providing storage for the NAS cluster or pool for which you want to change the Storage Prole.
6. From the Storage Prole drop-down menu, select a Storage Prole.
7. Click OK.
Import Migrated NAS Volume Data to the Lowest Storage Tier
Migrating large amounts of data to the FluidFS cluster can cause Storage Center upper-storage tiers to ll up, reducing write
performance for other applications. If you plan to migrate data from another NAS product to the FluidFS cluster, enable the Import
to Lowest Tier option before you begin the migration. This option temporarily congures the NAS volumes to write data to the
lowest tier dened in the Storage Prole congured for the NAS volumes, without waiting for data progression to move the data.
After data migration is complete, disable the Import to Lowest Tier option to resume normal operation using the congured Storage
Prole.
1. Congure the NAS volumes to write data to the lowest tier dened in the congured Storage Prole.
a. Click the Storage view and select a FluidFS cluster.
b. Click the Summary tab.
c. In the right pane, click Edit FluidFS Cluster Settings. The Edit FluidFS Cluster Settings dialog box appears.
d. Click the SC Storage Prole tab.
e. Select the Import to Lowest Tier check box.
