Abstract
Data storage federation equipment manages data storage arrays on behalf of host computers. In particular, the data storage federation equipment provides media type queries to the data storage arrays, each media type query requesting media type identification for a particular logical unit of storage (LUN) on a particular data storage array. The data storage federation equipment further receives, in response to the media type queries, media type responses from the data storage arrays, each media type response identifying media type for a particular LUN on a particular data storage array. The data storage federation equipment further performs, based on the media type responses, memory management operations that adjust operation of LUNs on the data storage arrays on behalf of the host computers. The memory management operations are performed while the data storage federation equipment remains interconnected between the host computers and the data storage arrays.
