Abstract
A host system performs I/O processing using metadata for a storage system, where none or some of the metadata is stored on the host system. The host system may be coupled to the global memory of the storage system along a communication path that includes an internal switching fabric of the storage system and does not include a network located externally to the storage system. The host system may exchange communications over the communication path to access indirection layers on the storage system to determine a global memory address of metadata corresponding to an I/O operation. The host system may include a host metadata table of global memory addresses for metadata of logical locations logical devices. The host system may query the host metadata table for a global memory address of metadata corresponding to a logical location specified in an I/O operation.
