Storage Types for SCv2000 Series Storage Systems
SCv2000 series controllers create a storage type for each disk class, and manage storage types automatically.
SCv2000 series series storage systems manage storage types automatically in the following ways:
Storage types are created automatically for each disk class
Storage types have a 2MB page size for HDD folders and a 512 KB page size for SSD folders
Storage types cannot be modified
Non-redundant storage types are not allowed
RAID Tiering for SCv2000 Series Storage Systems
RAID tiering for SCv2000 series storage systems moves data between RAID 10 and RAID 5/6, but it does not move data
between storage tiers.
Storage Profiles for SCv2000 Series Storage Systems
The following table summarizes the storage profiles available to SCv2000 series storage systems:
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 Efficiency 1
Writes: T1 RAID 5/6
Snapshots: T1 RAID 5/6
No
Balanced
The Balanced storage profile balances efficiency and performance for any volume using that storage profile.
When a volume uses the Balanced storage profile, 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 Efficiency
Maximize Efficiency writes new data to RAID 5/6 and keeps snapshot data on RAID 5/6. Use Maximize Efficiency for volumes
with less-important data and infrequently used data.
