Advantech DNS-3200 user manual To add a distributed spare while creating an array

Notes: 1. If there is insufficient unused space on the disks in an array, you cannot add a distributed spare without adding an additional disk and transforming to an array with distributed sparing enabled. The distributed spare option uses the equivalent storage of one of the disks in the array. For example: the total capacity of six drives is being used in a RAID5 array, and you have enabled distributed sparing, the capacity of the array is the same as a four-drive RAID0. The capacity of one disk is lost to the RAID5 parity data, and the capacity of another disk is lost to the distributed sparing option.

2. See “About Sparing Options”.

To add a distributed spare while creating an array:

1.On the Array menu, click Create.

2.Configure the array.

3.In the Distributed Spare field, click Enabled.
