Abstract
A method for dynamic write-back cache sizing in solid state memory storage. The method includes receiving a request to write a data fragment to a memory location of a storage medium, identifying a resource required for the writing, and obtaining a state of the resource. The state of the resource is governed by a number of data fragments that are stored in the write-back cache which require the resource. The number of data fragments in the write-back cache which require the resource are limited to enable writing of all data fragments in the write-back cache to the storage medium, within a specified amount of time. The method further includes determining that the state of the resource allows the received data fragment to be stored in the write-back cache, and based on the determination: storing the data fragment in the write-back cache and acknowledging the write request.
