Embedded scale-out aggregator for storage array controllers

摘要

Methods and systems for dynamic storage tiering may comprise: discovering one or more remote virtual drives associated with one or more remote storage arrays; advertising one or more local virtual drives associated with a local storage array; receiving one or more lO requests from a client addressed to one or more remote virtual drives associated with one or more remote storage arrays; transmitting one or more command descriptor block (CDB) requests to one or more remote storage arrays associated with the one or more virtual drives to allocate local cache space and transmitting the one or more lO requests to the one or more remote storage arrays via Remote Direct Memory Access (RDMA).
