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 Prole for a NAS Cluster or Pool
Storage Center Storage Proles control how Storage Center manages volume data. The selected Storage Prole 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 Proles, see the Storage Manager Administrator’s Guide.
View the Storage Prole for the NAS Cluster or Pool
View the Storage Center Storage Proles congured for the NAS cluster or pool. A unique Storage Prole can be congured 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 Prole tab. For each Storage Center, the Storage Prole is displayed in the right pane in the Storage
Prole drop-down menu.
Change the Storage Prole for the NAS Cluster or Pool
Change the Storage Center Storage Proles congured for the NAS cluster or pool. A unique Storage Prole can be congured 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 Prole tab.
5. Locate the Storage Center providing storage for the NAS cluster or pool for which you want to change the Storage Prole.
6. From the Storage Prole drop-down menu, select a Storage Prole.
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 congures the NAS volumes to write data to the
lowest tier dened in the Storage Prole congured 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 congured Storage
Prole.
1. Congure the NAS volumes to write data to the lowest tier dened in the congured Storage Prole.
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 Prole tab.
e. Select the Import to Lowest Tier check box.
