The IBM 93H4049 is an IBM Turboways 155 PCI Adapter, designed to enhance network connectivity and throughput. This high-performance network adapter provides an ATM (Asynchronous Transfer Mode) interface, operating at 155 Mbps, which is ideal for high bandwidth applications including multimedia, database clustering, and large-scale transaction processing. Its integration into a compatible PCI slot on servers or high-end workstations enables efficient and reliable data transfer across local area networks (LANs) and wide area networks (WANs). With its support for high-speed data exchange and robust error correction mechanisms, the IBM 93H4049 facilitates improved network performance and connectivity. It is particularly well-suited for environments demanding high levels of data integrity and transmission speed, such as financial institutions, research facilities, and large enterprise data centers.
