TRAID+ Introduction:
TRAID+ not only inherits all the excellent features of TRAID but also achieves a breakthrough in redundancy protection. While traditional TRAID provides fault tolerance for one disk failure, TRAID+ extends this to two disks, offering stronger protection for user data. This enhancement makes TRAID+ the ideal choice for users seeking higher-level data security.


Prerequisites:
To migrate from TRAID to TRAID+, your array must meet the following requirements: It must have at least three disks of the largest capacity. For example, if your current TRAID array consists of a mix of 1TB and 2TB disks, you will need at least three 2TB disks to upgrade to TRAID+.


1. The TRAID array already has three or more disks of the largest capacity

Steps:
1. Insert a new disk with a capacity equal to or larger than the largest disk in the current array.
2.Edit the storage pool and select the "Array Online Migration" function to initiate the migration process.

Case Studies:
User A Scenario: If the TRAID array consists of three 1TB disks, insert an additional disk with a capacity of at least 1TB to meet the migration requirements.
User B Scenario: If the TRAID array includes one 1TB disk and three 2TB disks, since the 2TB disks are the largest in the array and already number three, insert a new disk with a capacity of at least 2TB to proceed with TRAID+ migration.


2. The TRAID array currently has two disks of the largest capacity

Steps:
1. Insert a new disk with a capacity equal to the largest disk in the current array.
2. Edit the storage pool and select the "Add Disk to Array" function to incorporate the disk into the array.
3. Insert another new disk with a capacity equal to or larger than the largest disk in the current array.
4. Now, the TRAID array has three disks of the largest capacity. Edit the storage pool again, select another disk, and choose the "Array Online Migration" function to start the migration process.

Case Studies:
User C Scenario: If the TRAID array consists of two 1TB disks, add one 1TB disk to the array to bring the count of largest-capacity disks to three. Afterward, insert an additional disk with a capacity of at least 1TB to meet the migration requirements.
User D Scenario: If the TRAID array includes two 1TB and two 2TB disks, add one 2TB disk to the array to bring the count of largest-capacity disks to three. Afterward, insert an additional disk with a capacity of at least 2TB to meet the migration requirements.


3. The TRAID array currently has one disk of the largest capacity

Steps:
1.Insert a new disk with a capacity equal to the largest disk in the current array.
2. Edit the storage pool and select the "Add Disk to Array" function to incorporate the disk into the array.
3. Repeat Step 2 to add another disk to the array after synchronization completes.
4. Insert another new disk with a capacity equal to or larger than the largest disk in the current array.
5. Now, the TRAID array has three disks of the largest capacity. Edit the storage pool again, select another disk, and choose the "Array Online Migration" function to start the migration process.

Case Studies:
User E Scenario: If the TRAID array consists of one 1TB disk, sequentially add two 1TB disks to the array to bring the count of largest-capacity disks to three. Afterward, insert an additional disk with a capacity of at least 1TB to meet the migration requirements.
User F Scenario: If the TRAID array includes one 1TB, one 2TB, and one 4TB disk, sequentially add two 4TB disks to the array to bring the count of largest-capacity disks to three. Afterward, insert an additional disk with a capacity of at least 4TB to meet the migration requirements.
