ABSTRACT:
A system and method for zero copy block protocol write operations obviates the need to copy the contents of memory buffers (mbufs) at a storage system. A storage operating system of the storage system receives data from a network and stores the data in chains of mbufs having various lengths. An iSCSI driver processes (interprets) the received mbufs and passes the appropriate data and interpreted command to a SCSI target module of the storage operating system. The SCSI target module utilizes the mbufs and the data contained therein to perform appropriate write operations in response to write requests received from clients.
