Create Secure Data Disk Folder
A Secure Data folder can contain only SEDs that are FIPS certified. If the Storage Center is licensed for Self-Encrypting Drives
and unmanaged SEDs are found, the Create Disk folder dialog box shows the Secure Data folder option.
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. Click the Disks node.
The Disks view is displayed.
4. Click Create Disk Folder.
The Create Disk Folder dialog box opens. The dialog box displays all unmanaged disks and designates spare disks.
5. Select the Create as a Secure Data folder checkbox.
NOTE: All non-SEDs must be removed from the Unmanaged Disks table before creating a Secure Data folder.
6. Type a name in the Name field.
7. Select the disks to be managed and click OK.
The Secure Data Disk folder is created.
8. To modify the tier redundancy, select the Create Storage Type checkbox and then modify the redundancy for each tier as
needed.
● 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.)
9. Click OK.
Managing Data Redundancy
Manage data redundancy by modifying tier redundancy or creating Storage Types.
Redundancy Requirements
Drive size is used to determine the redundancy level to apply to a tier of drives. If any drive in a tier surpasses a threshold size,
a specific redundancy level can be applied to the tier containing that drive. If a redundancy level is required, the Storage Center
operating system sets the level and it cannot be changed.
Table 15. HDD Redundancy Recommendations and Requirements
Disk Size Level of Redundancy Recommended or Enforced
Up to 3 TB Dual redundant is the recommended level
NOTE: Non-redundant storage is not an option for SCv2000 Series storage systems.
3 TB and higher Dual redundant is required and enforced
Table 16. SSD Redundancy Recommendations and Requirements
Disk Size Level of Redundancy Recommended or Enforced
Up to 18 TB Dual redundant is the recommended level
