Hot Spare

A hot spare disk is a backup hard disk. When a hard disk in the storage pool fails, it can quickly and automatically take over to ensure the continuous and stable operation of the storage pool. To ensure performance and compatibility, it is recommended to choose a hot spare disk with the same model as the existing hard disks in the storage pool. The capacity of the hot spare disk should be at least equal to the smallest member disk in the storage pool; however, if your storage pool uses the TRAID or TRAID+ array type, the capacity of the hot spare disk should be at least equal to the largest member disk in the storage pool.

Management and Operations

Through the functional configuration buttons, you can perform the following operations:

Create: Create a hot spare disk for a storage pool. The creation must meet the following requirements:
 • The storage pool for which a hot spare disk needs to be created must have a redundant array type: TRAID (non‑single disk), TRAID+, RAID 1, RAID 5, RAID 6, RAID 10.
 • There must be an idle disk that meets the capacity requirements for joining the storage pool.

Edit: Switch the hot spare disk to another storage pool. The following requirements must be met:
 • The target storage pool must have a redundant array type.
 • The capacity of the hot spare disk must meet the requirements of the target storage pool.

Delete: Delete the created hot spare disk.

Note

1. During the process of creating a hot spare disk, the data in the selected disk will be deleted.
2. The capacity of the hot spare disk should be at least equal to the smallest member disk in the storage pool; however, if your storage pool uses the TRAID or TRAID+ array type, the capacity of the hot spare disk should be at least equal to the largest member disk in the storage pool.
