Tune in July 5 at 8 p. The Bonds and Betrayals of Brotherhood. Microsoft announces quarterly earnings release date. How TrialWatch app and other technology can help you navigate the Bus-Tech PCI-X ESCON Adapter system. Follow us: This library is stored on the hard disk in the server, and the procedures are loaded as required by the application.


The application passes data Bus-Tech PCI-X ESCON Adapter to and from the CID using the procedures contained in the library APAPIwhich is written in C for effective use with several types of operating systems. The writer of the application can choose to bypass several functions provided by the firmware and software provided with the adapter.

All categories

CCW processing, for example, can all be done in the application if the application writer chooses to do so. The CID is responsible for the organized movement and assured delivery of data that flows through the hardware adapter; Bus-Tech PCI-X ESCON Adapter is tailored for this task and normally does very little processing of the Channel Control Word CCW. It deals mostly in enqueuing and dequeuing data for the adapter and the application so that there is a smooth flow of cohesive messages from the application through the adapter to the channel and from the channel to the application.

The CID also sends commands to the adapter and checks status from the adapter to assure that the CCW is correctly formulated in the adapter and that information included in the CCW is Bus-Tech PCI-X ESCON Adapter for correctly handling the data packets. AP10 makes sure that there are buffers available when the Bus Interface firmware needs them, and it. AP10 makes sure that there are buffers available when the Bus Interface firmware needs them, and it controls when the Bus Bus-Tech PCI-X ESCON Adapter firmware starts the movement.

The Bus Interface firmware also performs error checking and error reporting on the data stream across the bus. The server designer can choose to do all of the CCW processing and only use the adapter for data movement. Bus-Tech PCI-X ESCON Adapter that case, the whole CCW and all of its associated data are passed through a transparent Emulation firmware package. If the server designer chooses the Emulation firmware packages, the CCW is processed in the Emulation firmware and the adapter appears to the channel as if it were an IBM device.

ESCON definition of ESCON by Medical dictionary

This relieves the application of many of the housekeeping chores associated with CCW processing. This adapter consists of two physical cards connected together through on-card connectors.


These connectors carry a secondary PCI Bus that is much like the bus that is used on the base of the primary Bus-Tech PCI-X ESCON Adapter that interfaces with the server. This secondary PCI Bus is used for communication between the primary card and the secondary card. The CCW information is embedded within these frames. The firmware and software beyond the secondary PCI Bus boundary do not have to be concerned with the low-level operation of Bus-Tech PCI-X ESCON Adapter physical channel. The PMC firmware and hardware completely handle that part of the data movement.

Host adapter

It becomes transparent to the higher-level structures. The adapter in both cases handles the orderly, error-protected movement of the data from the channel into the application software.
