RAID Tiering for SCv2000 Series Controllers
RAID tiering for SCv2000 series controllers moves data between RAID 10 and RAID 5/6. It does not move data between storage tiers. RAID
tiering happens at 7 PM every day. Data progression runs until it completes or reaches the maximum run time.
Storage Proles for SCv2000 Series Controllers
The following table summarizes the storage proles 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 Eciency 1
Writes: T1 RAID 5/6
Snapshots: T1 RAID 5/6
No
Balanced
The Balanced storage prole balances eciency and performance for any volume using that storage prole.
When a volume uses the Balanced storage prole, 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 Eciency
Maximize Eciency writes new data to RAID 5/6 and keeps snapshot data on RAID 5/6. Use Maximize Eciency for volumes with less-
important data and infrequently used data.
User Interface for Storage Center Management
Most storage conguration and management is performed from the Unisphere dashboard. The dashboard view varies slightly depending on
whether you connect directly to a Storage Center or connect through the Data Collector.
Home Page
When connected through the Data Collector, a Home page displays an aggregate summary of all Storage Centers managed by the Data
Collector.
