IBM 4765 cryptographic coprocessor

This paper provides an overview of the 4765 cryptographic coprocessor hardware and firmware architecture, its key design features, and an overview of the IBM System z® secure software stack. The hardware for the 4765 solution is shared across all IBM server platforms offering cryptographic hardware acceleration in a highly programmable coprocessor environment designed to meet the most stringent security requirements. Its internal hardware and firmware can be easily updated to meet new security standards and requirements, as well as new customer-specific functionality. It allows updates and customization to be executed with zero downtime, meeting the highest standard of reliability and availability. Standard cryptographic functions and specialized banking and financial functions are supported.

IBM system z10 open systems adapter ethernet data router

The IBM Open Systems Adapter (OSA) is a family of integrated hardware features that enables direct connection between IBM System z10™ hosts and clients on local area networks (LANs). The OSA provides a virtual interface to the LAN that may be shared by hundreds of host operating systems. The newest OSA generation employs a hardware-based Ethernet virtualization offload engine to significantly increase throughput and reduce latency in line with the latest 1-Gb and 10-Gb Ethernet adapters. The router is embodied in the OSA Ethernet data router ASIC (application-specific integrated circuit) chipset and is packaged in several configurations. This paper describes the function of the OSA Ethernet data router, its hardware architecture, and the implementation of the design.
