Selecting physical disks

Use the Select Physical Disks screen to select the physical disks to be used for the virtual drive and select the physical disk drive-related properties.

The number of physical disks required for the virtual disk varies depending on the RAID level. The minimum and maximum numbers of physical disks required for the RAID level are displayed on the screen.

Protocol — Select the protocol for the disk pool: Serial Attached SCSI (SAS) or Serial ATA (SATA). SAS drives are used for high performance, while SATA drives provide a more cost-effective solution. A disk pool is a logical grouping of physical disk drives on which one or more virtual drives can be created. The protocol is the type of technology used to implement RAID.
Media Type — Select the media type for the disk pool: Hard Disk Drives (HDD) or Solid State Disks (SSD). HDDs use traditional rotational magnetic media for data storage and SSDs implement flash memory for data storage.
Encryption Capability — Select Yes to enable encryption capability.
Select Span Length — Select the span length. The span length value refers to the number of physical disk drives included in each span. Span length applies only to RAID 10, RAID 50, and RAID 60. The Select Span Length drop‑down list is active only if you have selected RAID 10, RAID 50, or RAID 60.
Drives remaining for current span — Displays the number of physical disk-drives remaining in the current span based on the span length value selected.
Select the physical disk-drives using the check boxes at the bottom of the screen. The physical disk-drive selection must meet the requirements of the RAID level and span length. To select all the physical disk-drives, click Select All. After you select the option, the option changes to Deselect.
