pdisk descriptions
The pdisk description indicates whether the RAID format physical disk is configured as an array member, hot-spare disk, or an array candidate.
For an array, the description column of the List SAS Disk Array Configuration screen indicates the RAID level of the array. The description column for a pdisk indicates whether the disk is configured as an array member, hot-spare disk, or an array candidate.
- Array Member
- A 528 bytes per sector HDD pdisk that is configured as a member of an array.
- Hot Spare
- A 528 bytes per sector HDD pdisk that can be used by the controller to automatically replace a failed disk in a degraded RAID disk array. A hot-spare disk is useful only if its capacity is greater than or equal to the capacity of the smallest disk in an array that becomes degraded. For more information about hot spare disks, see Using hot-spare disks.
- Array Candidate
- A 528 bytes per sector HDD pdisk that is a candidate for becoming an array member or a hot-spare disk.
- SSD Array Member
- A 528 bytes per sector solid-state pdisk that is configured as a member of an array.
- SSD Hot Spare
- A 528 bytes per sector solid-state pdisk that can be used by the controller to automatically replace a failed disk in a degraded RAID disk array. A hot spare disk is useful only if its capacity is greater than or equal to the capacity of the smallest disk in an array that becomes degraded. For more information about hot spare disks, see Using hot-spare disks.
- SSD Array Candidate
- A 528 bytes per sector solid-state pdisk that is a candidate for becoming an array member or a hot-spare disk.
- RI (Mainstream) Array Member
- A 528 bytes per sector read intensive (RI) solid-state pdisk that is configured as a member of an array.
- RI (Mainstream) Hot Spare
- A 528 bytes per sector read intensive (RI) solid-state pdisk that can be used by the controller to automatically replace a failed RI disk in a degraded RAID disk array. A hot spare disk is useful only if its capacity is greater than or equal to the capacity of the smallest disk in an array that becomes degraded. For more information about hot spare disks, see Using hot-spare disks.
- RI (Mainstream) Array Candidate
- A 528 bytes per sector read intensive (RI) solid-state pdisk that is a candidate for becoming an array member or a hot-spare disk in an array.
- 4K Array Member
- A 4224 bytes per sector hard disk drive (HDD) pdisk that is configured as a member of an array.
- 4K Hot Spare
- A 4224 bytes per sector HDD pdisk that can be used by the controller to automatically replace a failed disk in a degraded RAID disk array. A hot-spare disk is useful only if its capacity is greater than or equal to the capacity of the smallest disk in an array that becomes degraded. For more information about hot spare disks, see Using hot-spare disks.
- 4K Array Candidate
- A 4224 bytes per sector HDD pdisk that is a candidate for becoming an array member or a hot-spare disk.
- 4K SSD Array Member
- A 4224 bytes per sector solid-state pdisk that is configured as a member of an array.
- 4K SSD Hot Spare
- A 4224 bytes per sector solid-state pdisk that can be used by the controller to automatically replace a failed disk in a degraded RAID disk array.

- 4K RI (Mainstream) Hot Spare
- A 4224 bytes per sector read intensive (RI) solid-state pdisk that can be used by the controller to automatically replace a failed RI disk in a degraded RAID disk array. A hot spare disk is useful only if its capacity is greater than or equal to the capacity of the smallest disk in an array that becomes degraded. For more information about hot spare disks, see Using hot-spare disks.
- 4K RI (Mainstream) Array Candidate
- A 4224 bytes per sector read intensive (RI) solid-state pdisk that is a candidate for becoming an array member or a hot-spare disk for in an array.
- 4K ENL Array Member
- A 4224 bytes per sector Enterprise Nearline (ENL) hard disk drive (HDD) pdisk that is configured as a member of an array.
- 4K ENL Hot Spare
- A 4224 bytes per sector ENL HDD pdisk that can be used by the controller to automatically replace a failed ENL disk in a degraded RAID disk array. A hot spare disk is useful only if the capacity is greater than or equal to the capacity of the smallest disk in an array that becomes degraded. For more information about hot spare disks, see Using hot-spare disks.
- 4K ENL Array Candidate
- A 4224 bytes per sector ENL HDD pdisk that is a candidate for becoming an array member or a hot spare disk in an array.
