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 everyday. 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 Tier 1. 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.
