Quick Start

9 Changing the redundancy mode

It is possible to change the Acronis Storage redundancy mode from Evaluation to Express, and from

Express to Advanced.

Before changing the redundancy mode, consider the following:

 Changing the mode causes no storage system downtime.

 Changing the mode increases the redundancy overhead for the data that is already present in the

storage. As a result, the total occupied space will increase.

9.1 Evaluation mode to Express mode

1. In the Acronis Storage web console, click the Settings tab.

2. Click Redundancy mode.

3. Select Express.

4. Click Apply.

The system starts creating additional parity chunks for the data. On the Storage tab, the system state

changes to System is under risk.

The total size of chunks to create is shown in the Redundancy health section of the Storage tab.

After all additional chunks are created, the system state changes to System is stable, which means

that the redundancy mode was successfully changed.

9.2 Express mode to Advanced mode

To change the mode to Advanced, you must have eight physical nodes that meet the hardware

requirements (p. 6).

9.2.1 Booting the physical servers

Ensure that the physical servers are connected to the Acronis Storage private network.

1. Boot the physical servers from an expansion ISO or from a PXE server, as described in "Booting

up other nodes" (p. 11).

2. Assign only the STS roles to the nodes' disks, as described in "Roles assignment" (p. 13).
