You can now proceed with either creating data buckets in the Couchbase cluster by using the Couchbase profile either in combination with Distributed Storage, or with PCC. Couchbase data buckets can be created either directly in the Couchbase Web Console, or by using Couchbase profiles. See the Desktop User's Guide for further information about how to create buckets with Couchbase profiles.
