Check the Status of a RAID Rebalance
The RAID Rebalance displays the status of an in-progress RAID rebalance and indicates whether a rebalance is needed.
1 If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2 Click the Storage tab.
3 In the Storage tab navigation pane, select Disks.
4 Click Rebalance RAID.
The RAID Rebalance dialog box shows the status of a RAID rebalance.
5 Click OK.
Managing Storage Types
Storage Types determine how Data Progression moves data within a disk folder. Each disk folder has a corresponding Storage Type.
NOTE: Modifying tier redundancy requires a RAID rebalance to be completed, and should not be performed unless sucient free
disk space is available within the disk folder.
Create a Storage Type
Creating a Storage Type sets the redundancy level for each tier and assigns the Storage Type to a disk folder.
Prerequisite
SCv2000 does not support creating new Storage Types.
About this task
NOTE
: Do not assign multiple Storage Types to one disk folder. Data Progression may not perform as intended with multiple
Storage Types assigned to one disk folder.
Steps
1 If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2 Click the Storage tab.
3 In the Storage tab navigation pane, click Storage Types, then click Create Storage Type.
The Create Storage Type dialog box opens.
4 Select a disk folder from the Disk Folder drop-down menu.
5 Select a redundancy type.
• Redundant: Protects against the loss of any one drive (if single redundant) or any two drives (if dual redundant).
• Non-Redundant: Uses RAID 0 in all classes, in all tiers. Data is striped but provides no redundancy. If one drive fails, all data is lost.
NOTE
: Non-Redundant is not recommended because data is not protected against a drive failure. Do not use non-
redundant storage for a volume unless the data has been backed up elsewhere.
6 For Redundant Storage Types, you must select a redundancy level for each tier unless the drive type or size requires a specic
redundancy level
• Single Redundant: Single-redundant tiers can contain any of the following types of RAID storage:
– RAID 10 (each drive is mirrored)
– RAID 5-5 (striped across 5 drives)
– RAID 5-9 (striped across 9 drives)
• Dual redundant: Dual redundant is the recommended redundancy level for all tiers. It is enforced for 3 TB HDDs and higher and for
18 TB SSDs and higher. Dual-redundant tiers can contain any of the following types of RAID storage:
– RAID 10 Dual-Mirror (data is written simultaneously to three separate drives)
