the class RPBlockServiceApiImpl method prepareRecommendedVolumes.

/**
 * Prepare Recommended Volumes for Protected scenarios only.
 *
 * This method is responsible for acting the same as the unprotected "prepareRecommendedVolumes" call,
 * however it needs to create multiple volumes per single volume requests in order to generate protection.
 *
 * Those most typical scenario is, that for any one volume requested in a CRR configuration, we create:
 * 1. One Source Volume
 * 2. One Source Journal Volume (minimum 10GB, otherwise 2.5X source size)
 * 3. One Target Volume on protection varray
 * 4. One Target Journal Volume on protection varray
 *
 * In a CLR configuration, there are additional volumes created for the Local Target and Local Target Journal.
 *
 * This method will assemble a ProtectionSet object in Cassandra that will describe the Protection that
 * will be created on the Protection System.
 *
 * When other protection mechanisms come on board, the RP-ness of this method will need to be pulled out.
