Table 16. SSD Redundancy Recommendations and Requirements (continued)
Disk Size Level of Redundancy Recommended or Enforced
NOTE: Non-redundant storage is not an option for SCv2000 Series storage systems.
18 TB and higher Dual redundant is required and enforced
Managing RAID
Modifying tier redundancy, or adding or removing disks can cause data to be unevenly distributed across disks. A RAID rebalance
redistributes data over disks in a disk folder.
Rebalance RAID
Rebalancing RAID redistributes data over the disks according to the Storage Type. Rebalance the RAID after releasing a disk
from a disk folder, when a disk fails, or after adding a disk.
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 opens. If a RAID rebalance is needed, the dialog box shows RAID rebalance options.
5. Select Perform RAID Rebalance immediately.
6. Click OK.
Cancel a RAID Rebalance
Cancel a RAID rebalance to stop an on-going RAID rebalance. Cancelling a RAID rebalance does not cancel the need to
rebalance. You will still be prompted to rebalance RAID.
