Flash Only with Progression (Tier 1 to Tier 2)
The Flash Only with Progression storage prole performs initial writes on high-performance Tier 1 drives. Less active data progresses to
Tier 2, but remains on SSDs. This prole is useful for storing volumes with data that requires optimal read performance, such as golden
images, linked clones, and some databases.
Low Priority with Progression (Tier 3 to Tier 2)
The Low Priority with Progression storage prole directs initial writes to less expensive Tier 3 (RAID 10) drives, and then allows frequently
accessed data to progress to Tier 2. This prole is useful for migrating large amounts of data to Storage Center without overloading Tier 1
SSDs.
Storage Proles for SCv2000 Series Controllers
The following table summarizes the storage proles available to SCv2000 series controllers.
Name Initial Write Tier Tier (T) and RAID Levels RAID Tiering
Balanced 1
Writes: T1 RAID 10
Snapshots: T1 RAID 5/6
Between RAID types only
Maximize Performance 1
Writes: T1 RAID 10
Snapshots: T1 RAID 10
No
Maximize Eciency 1
Writes: T1 RAID 5/6
Snapshots: T1 RAID 5/6
No
Balanced
The Balanced storage prole balances eciency and performance for any volume using that storage prole.
When a volume uses the Balanced storage prole, all new data is written to RAID 10. When Storage Center creates a snapshot, Data
Progression moves snapshot data from RAID 10 to RAID 5/6.
Maximize Performance
Maximize Performance keeps new data and snapshot data on RAID 10 to increase performance. Maximize Performance is useful for
volumes with important and frequently used data.
Maximize Eciency
Maximize Eciency writes new data to RAID 5/6 and keeps snapshot data on RAID 5/6. Use Maximize Eciency for volumes with less-
important data and infrequently used data.
User Interface for Storage Center Management
Most storage conguration and management for an individual Storage Center is performed from the Storage view in the Storage Manager
Client. Select a Storage Center in the Storage navigation pane to view and manage it.
The following tabs appear in the display pane when a Storage Center is selected:
