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.
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, 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
sufficient 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.
Prerequisites
SCv2000 series storage systems do 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 specific
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)
• RAID 6-6 (4 data segments, 2 parity segments for each stripe)
• RAID 6-10 (8 data segments, 2 parity segments for each stripe.)
7. Drive Addition is selected by default. Leave this option selected.
