1. An apparatus, comprising:

  • non-transitory storage media configured as a cache associated with a computing machine;

    wherein the computing machine is a member of a cluster of computing machines that share access to a storage device; and

    a cluster caching logic associated with the computing machine, wherein the caching logic is configured to;

    communicate with cluster caching logics associated with the other computing machines to determine an operational status of a clique of cluster caching logics performing caching operations on data in the storage device; and

    selectively enable caching of data from the storage device in the cache based, at least in part, on a membership status of the cluster caching logic in the clique.
