Computer systems process, store and transmit data. Seemingly, storage and transmission are dissimilar. Despite the difference, the properties of services are comparable: effectiveness, security, reliability. The requirements are accomplished with the same methods: data structure, coding, compression, redundancy. The convergence between the services is noticeable. In the paper, some concepts, such as how to utilize the convergence to optimize the system performance, are presented. For example, in a file transmission procedure: sectors of disk are read, their checksums are examined and a file is assembled; communication software divides the file into packets, assigns new checksums and transmits data; on the receiver side the checksums are examined, the packets are assembled into a file and forwarded to the storage system; during write process a file is divided into sectors; sectors are given checksums and are stored. In the paper, more effective scheme is proposed. First, a disk sector is read and its checksum is examined. Then the sector is placed in the packet data field and the sector checksum is placed in the packet checksum field. The packet is transmitted. On the receiver side the sector and its checksum are stored. The unification of other elements of storage and transmission such as: channel coding, compression technique is also evaluated in the paper.
