1. A clustered computerized system, comprising: a set of hosts that includes a first host and a second host, wherein each host in the set of hosts includes at least one processor; a network infrastructure for interconnecting the hosts of the set; a set of solid state memories, each one of the set of solid state memories comprised in one host in the set of hosts, wherein each solid state memory in the set of solid state memories caches data and metadata of the cached data corresponding to its respective host; a clustered file system shared between the hosts of the set that provides the first host with coherent and transparent access to the metadata corresponding to the cached data of the second host, wherein the clustered file system stores the metadata and does not store the cached data; and a set of first kernel components and a set of second kernel components executing on each of the set of hosts, wherein the set of first kernel components corresponds to the clustered file system and manages the metadata, and wherein the set of second kernel components manages the cached data.
