Dell PowerFlex 4.6.x Technical Overview

Setting up replication

You are required to initially prepare the infrastructure to use replication in PowerFlex.

The following is an overview of the necessary steps.

1. Add peer systems, at both the source and target systems. Add the corresponding certificates to each system.
2. Add journal capacity, ensuring sufficient capacity.
3. Add SDRs, at least two per protection domain that has replicated volumes.

Perform the following steps to configure replication:

1. Create the replication consistency group. Define the recovery point objective.
2. Add volume pairs. Volumes in a volume pair must have the same size. It is not necessary but is recommended that they have the same attributes (medium/fine granularity, zero padded/non-zero padded).

   If both systems are 4.x or higher then the target volumes may be automatically provisioned when the pair is created.

3. If the replication consistency group was created as active (the default), then initial copy is started automatically. Otherwise, the replication consistency group must be activated before the initial copy is started.
