Storage Virtualization for SCv2000 Series Storage
Systems
SCv2000 series storage systems automatically manage many of the storage virtualization options.
Disk Management on SCv2000 Series Storage Systems
SCv2000 series storage systems manage disks automatically, limiting the disk management options. After adding disks, Storage Center
recognizes the new disks, creates a new disk folder if necessary, then manages the disks in the disk folder. If a disk is intentionally down
for testing purposes, then is deleted, you can restore the disk to manage the disk again in a disk folder.
The following disk management options are not available for SCv2000 series storage systems:
• Creating disk folders
• Adding disks to disk folders
• Managing disk spares
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.
