Encrypting A Virtual Disk
Does my controller support this feature? See Supported Features.
The Encrypt Virtual Disk task encrypts an unencrypted virtual disk. This feature is only applicable to controllers that:
• Are encryption capable (PERC H700, PERC H710 Adapter, PERC H710 Mini Blades, PERC H710 Mini Monolithic, PERC H710P Adapter,
PERC H710P Mini Blades, PERC H710P Mini Monolithic, PERC H800, PERC H810 Adapter, PERC H730 Adapter, PERC H730 Mini
Monolithic, PERC H730 Mini Blades, PERC H730P Adapter, PERC H730P Mini Monolithic, PERC H730P Mini Blades, PERC H730P
Slim, PERC H740P Adapter, PERC H740P Mini Monolithic, PERC H830 Adapter, PERC H730P MX, PERC H745P MX, PERC H840
Adapter and PERC FD33xD/FD33xS)
• Have an Encryption Key
• Have Self Encryption Drives (SEDs) virtual disks
Create Virtual Disk Express Wizard
Does my controller support this feature? See Supported Features.
The Create Virtual Disk Wizard allows you to select the wizard type and the RAID level. The Create Virtual Disk Express Wizard
calculates the appropriate virtual disk conguration based on the available space and controller considerations. To make your own selections
for the virtual disk conguration, select the Advanced Wizard option.
Before creating a virtual disk, you should be familiar with the information in Considerations Before Creating Virtual Disks. You may also want
to review Choosing RAID Levels And Concatenation.
NOTE
: This task is not supported on PERC hardware controllers running in HBA mode.
To create a virtual disk using the Create Virtual Disk Express Wizard:
1 In the Server Administrator window, expand System > Storage.
2 Click Connector 0 (RAID).
The Virtual Disk(s) on Controller <Controller Name> page is displayed.
3 Click Go to the Create Virtual Disk Wizard.
The Create Virtual Disk Wizard (Step 1) <Controller Name> page is displayed.
4 Select the Express Wizard option and the RAID level from the drop-down list.
• Depending on the controller, Concatenated enables you to combine the storage capacity of several disks or to create a virtual disk
using a single physical disk. For more information about the number of supported physical disks when using Concatenated, see
Number Of Physical Disks Per Virtual Disk. Concatenated does not provide data redundancy or aect the read/write performance.
• Select RAID 0 for striping. This selection groups n disks together as a large virtual disk with a total capacity of n disks. Data is
alternately stored in the disks so that they are evenly distributed. Data redundancy is not available in this mode. Read/write
performance is enhanced.
• Select RAID 1 for mirroring disks. This selection groups two disks together as one virtual disk with a capacity of one single disk.
The data is replicated on both disks. When a disk fails, the virtual disk continues to function. This feature provides data redundancy
and good read performance, but slightly slower write performance. The system must have at least two physical disks to use RAID
1.
• Select RAID 5 for striping with distributed parity. This selection groups n disks together as one large virtual disk with a total
capacity of (n-1) disks. When a disk fails, the virtual disk continues to function. This feature provides better data redundancy and
read performance, but slower write performance. The system must have at least three physical disks to use RAID 5.
• Select RAID 6 for striping with additional distributed parity. This selection groups n disks as one large virtual disk with a capacity of
(n- 2) disks. The virtual disk remains functional with up to two disk failures. RAID 6 provides better read performance, but slower
write performance. The system must have at least four physical disks to use RAID 6.
• Select RAID 10 for striping over mirror sets. This selection groups n disks together as one large virtual disk with a total capacity of
(n/2) disks. Data is striped across the replicated mirrored pair disks. When a disk fails, the virtual disk continues to function. The
data is read from the surviving mirrored pair disk. This feature provides the best failure protection, read and write performance. The
system must have at least four physical disks to use RAID 10.
