Abstract:
A data storage system includes multiple tiers of data storage accessible by multiple hosts. The multiple tiers include an upper tier having a lower access latency and a lower tier having a higher access latency. For each extent among a plurality of extents of file system objects in the data storage, the storage controller separately tracks, for each of one or more hosts that access the extent, a respective heat indicative of a frequency of access by that host. In response to an event disassociating a first host among the multiple hosts from a particular extent among the plurality of extents, the storage controller recalculates an overall heat of the particular extent while excluding a first heat of the first host for the particular extent. The storage controller migrates extents among the multiple tiers based on overall heats of the plurality of extents.

Claim (Index 15):
The computer program product of  claim 14 , wherein the migrating comprises migrating in response to the event disassociating the first host from the particular extent.
