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.

1. If you are connected to a Data Collector, select a Storage Center from the drop-down list in the left navigation pane of Unisphere Central.
2. From the STORAGE menu, click Disks.
   The Disks view is displayed.
3. In the right pane, right-click Disks and select New Disk Folder from the drop-down menu.
   The New Disk Folder dialog box opens. The dialog box displays all unmanaged disks and designates spare disks.
4. 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.
5. Type a name in the Name field.
6. Select the disks to be managed and click OK.
   The Secure Data Disk folder is created.
7. 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.)
8. Click OK.
