The following configuration defines an additional tiered storage solution. The default content store is not changed. An additional set of secondary stores is defined (tier1, tier2 and tier3). As content ages (old infrequently used files), it can be moved to lower tiers. If the tiered storage is slow, a Caching content store can be placed in front.
