HYDRAź 3000:
Channel Interface
The HYDRA 3000 Channel Interface Module provides the I/O logic and high-speed communications path to the host mainframe block or byte multiplexor channel, and is compatible with S/390, ES/9000, 360/370, 30xx, 43xx, 9370, P390, or compatible CPUs. Physical connection is via customer-provided bus and tag channel cables. With the appropriate companion interface modules, the Channel Interface Module can simultaneously support SNA, non-SNA, DSPU, RJE, PNET, BSC, SDLC, TCP/IP, TRN, Ethernet, and multi-CPU channel-to-channel protocols with up to 256 CUUs. No FEP (Front-End Processor) or NCP (Network Control Program) is required.
Up to 16 Channel Interface Modules per HYDRA can be utilized, enabling the HYDRA 3000 to be connected to multiple mainframes either directly or via a channel extender. Since ETHERNET and TOKEN RING modules are also viewed by the hardware system as "channel related" systems, you can mix & match combinations of "Bus & Tag" , TOKEN RING, ETHERNET to a maximum of 16 modules per chassis.
This can then be multiplied further through HYDRA-Link connections (See Resource Sharing). Combined with multi-session support, each HYDRA 3000 connection can have access to all host CPUs by simply hot-keying between sessions. The HYDRA 3000 operates on channels shared with other controllers, front-end processors, or system printers, or on an unshared channel.
