A method is used in managing multi-tiered storage pool provisioning. One or more physical devices of a data storage system are configured for use in connection with provisioning a storage pool. A provisioning specification is received describing a RAID type and an auto-tiering selection. A rule is received describing one or more sets of data storage system best practices. Each of the one or more sets specifies data storage system best practices for a different type of data storage system including a first type associated with the data storage system. Configuration processing is performed in connection with initialization of the data storage system to configure a first portion of the one or more physical devices for use with auto-tiering in the storage pool. A rules engine and best practices for the first type of data storage system specified in the rule are used in performing the configuration processing.
