 Cache Tiering

 A cache tier provides Ceph Clients with better I/O performance for a subset of
 the data stored in a backing storage tier. Cache tiering involves creating a
 pool of relatively fast/expensive storage devices (e.g., solid state drives)

 Erasure-coded pools and cache tiering
 -------------------------------------
 
+.. note:: Cache tiering is deprecated in Reef.
+
 Erasure-coded pools require more resources than replicated pools and
 lack some of the functionality supported by replicated pools (for example, omap).
 To overcome these limitations, one can set up a `cache tier <../cache-tiering>`_
