Host-defined I/O storage control based on application instance and/or control group
View Patent ↗I/O storage processing behavior is controlled on a storage system based on an application instance of an I/O request. I/O storage processing behavior may be associated with application instances on a host by creating a table or other data structure that assigns identifiers to each application instance and specifies associate behavior(s) with the application instance. The table may associate behavior to application instances based on logical groupings of application instances, which may be based on existing defined groups or other logical entities, for example, a container or VM. A host may communicate the table to a storage system, and the storage system may store information from the table. An I/O request on the host may be tagged with an ID from the table, and sent to the storage system, which controls the I/O storage processing of the I/O request according to the tagged ID.
