Abstract: Embodiments are directed towards apparatuses, methods, and systems associated with a storage reclamation manager that generates a command to reclaim storage locations to assist in management of a storage capacity of a primary storage device. In embodiments, the command is a trim command to inform the storage device of storage locations including invalid data. In embodiments, the command is generated during performance of operations associated with a write-back operation where a cache coupled with the processor stores a first portion of data and the primary storage device stores a corresponding second portion of data. In embodiments, the command is generated during or after a write-back operation of a third portion of data into the cache device. In embodiments, the command assists in reclamation of storage locations in which the second portion of data is stored, to assist in management of a storage capacity of the primary storage device. Additional embodiments may be described and claimed.
