34902001 Application Field and Working Principle

The 34902001 is an evolutionary system from IBM that provides automated tape library enhancement for proper archiving and storage of data. It is mainly used in storage-oriented operations, such as backups and archive protection, where large amounts of sequential data is read and written.The main features of the 34902001 include high-speed sequential data access, small cataloguing time, low cost, and high reliability. It supports IEEE-compatible networking operations and provides compatibility with both 3490 and 3490E models. Additionally, it is capable of dynamic memory allocation, allowing users to maintain an efficient data structure.The system\'s main application field is enterprise-wide computing. It is used for automated storage, archiving and data protection, as well as for controlling the data movement created by the implementation of new systems. At the heart of the 34902001 resides a tape library controller, which enables the system to communicate with up to sixty-four media paths. It speeds up the data exchange between the media and the host server, and makes it more efficient and reliable. The system\'s working principle is based on the use of the IBM System/370 broadcast network protocol (BNP), and is designed to increase the performance of the tape library. The BNP protocol is the core technology, responsible for communication between the host system and the tape library. The 34902001 allows two types of communication between the host system and the tape library – LAN and tape signaling. LAN communications involve the use of standard Ethernet or Token-Ring networks, allowing large amounts of data to be transferred across the LAN. Tape signaling allows users to send commands from the host system, specifying the specific actions that are to be applied to the tape library. The tape library controller received data from the host system, and then sends the commands to the Robot Controller. The Robot Controller then executes the commands and returns the results back to the host system. In this way, all the system\'s operations are managed effectively and efficiently.In conclusion, the 34902001 is an important tool in the storage industry. It provides many advantages, from improved data access speed to enhanced archiving and data protection. Its features also ensure that the system is reliable and secure.
