Abstract: A computer-based system and method for providing a distributed write buffer in a storage system, including: obtaining a write request at a primary storage server to store data associated with the write request in a non-volatile storage of the primary storage server; and storing the data associated with the write request in a persistent memory of the primary storage server or in a persistent memory of an auxiliary storage server based on presence of persistent memory space in the primary storage server. The write request may be acknowledged by the primary storage server after storing the data associated with the write request in the persistent memory of the primary storage server or in the persistent memory of the auxiliary storage server.
