5. Select the Advanced Wizard option.
6. To make sure that only encrypted physical disks are used to create the virtual disk, select Yes from the Create Encrypted Virtual
Disk drop-down list.
The RAID levels are available for selection based on the number of encrypted physical disks.
If you select No, the RAID levels are available based on the total number of physical disks present on the system.
7. Select the required RAID level from the drop-down menu.
8. Select Bus Protocol.
The options are:
• SAS
• SATA
9. Select Media Type.
The available options are:
• HDD
• SSD
10. Click Continue.
NOTE: If you are creating an encrypted virtual disk, only the encrypted physical disks are displayed. Else, both
encrypted and unencrypted physical disks are displayed.
Example:
Connector 0
The Connector section of the page displays the connectors on the controller and the disks attached to each connector. Select the
disks you want to include in the virtual disk. In this example, the controller has a single connector with five disks.
• Physical disk 0:0
• Physical disk 0:1
• Physical disk 0:2
• Physical disk 0:3
• Physical disk 0:4
Physical Disks Selected
The Physical Disks Selected section of the page displays the disks you have chosen. In this example, two disks are selected.
• Physical disk 0:0
• Physical disk 0:1
Each RAID level has specific requirements for the number of disks that must be selected. RAID 10, RAID 50, and RAID 60 also have
requirements for the number of disks that must be included in each stripe or span.
If the controller is a SAS controller with firmware version 6.1 and later, and you selected RAID 10, RAID 50, and RAID 60, the user
interface displays the following:
• All Disks—Enables you to select all the physical disks in all the enclosures.
• Enclosure—Enables you to select all physical disks in the enclosure.
NOTE:
The All Disks and Enclosure options enable you to edit spans after selecting the physical disks that comprise
them. You can remove a span and specify a span again with different physical disks before proceeding.
• Number of Disks per Span — Enables you to select the number of disks in each span (default = 2). This option is available only
on SAS controllers with firmware version 6.1 and later.
NOTE:
This option is available only if Intelligent Mirroring is selected on the Create Virtual Disk Advanced Wizard
page.
NOTE: On a SAS controller with firmware version 6.1 and later, RAID 10 supports only even number of disks per
span and a maximum of 8 spans with 32 disks in each span.
Let us consider that the controller has three enclosures with six physical disks each (total number of available disks = 3 x 6 =18
disks). If you select four disks per span, the controller creates four spans (18 disks/4 disks per span = 4 spans). The last two disks
of the last enclosure are not part of RAID 10.
