Hot Spare Disk

A hot spare disk is a standby hard drive that can quickly take over when a disk in the storage pool fails, ensuring 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 disks in the storage pool. The capacity of the hot spare should be at least equal to the smallest member disk in the storage pool; however, if your storage pool uses TRAID or TRAID+ array types, the hot spare's capacity should be at least equal to the largest member disk in the pool.

Management and Operations

Using the buttons in the feature configuration, you can perform the following operations:

Create: Create a hot spare disk.

Edit: Assign the hot spare to an available storage pool.

Delete: Delete an existing hot spare disk.

Note

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