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 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 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.
