solution. A disk pool is a logical grouping of physical disks on which one or

more virtual disks can be created. The protocol is the type of technology

used to implement RAID.

• Select the media type for the disk pool from the

Media Type

drop-down

menu:

Hard Disk Drives (HDD)

Solid State Disks (SSD)

. HDDs use

traditional rotational magnetic media for data storage, and SSDs

drop-down menu.

The span length value refers to the number of physical disks included in

each span. Span length applies only to RAID 10, RAID 50, and RAID 60.

The

Select Span Length

drop-down menu is active only if the user has

selected RAID-10, RAID-50, or RAID 60.

• Select the physical disks using the check boxes at the bottom of the screen.

Your physical disk selection must meet the requirements of the RAID level

and span length. To select all of the physical disks, click

Select All

Click Next after making your selections.
