FDDIcontroller/PCI Adapters DEFPA-DB PCI FDDI SC/RJ-12 (PC/Mac)
The DEFPA-DB, a new addition to the DEC FDDI controller/PCI family of PCI-to-FDDI adapters, provide 100 Mbits-per-second FDDI LAN connectivity for any PCI V2.1-compliant host platform, and are backward-compatible with any PCI V2.0-compliant host platform. The PCI I/O bus and FDDI industry standards, together with the robust DIGITAL DMA engine adapter architecture, deliver a LAN adapter technology that provides high system-level availability, resiliency under load (host system and network) and transparent fault tolerance with auto-failover. Ring wrap and dual homing, the inherent auto-failover characteristics of the FDDI dual-ring architecture, provide a level of transparent fault tolerance and redundancy not available in other LAN technologies. For enterprise-wide full-duplex support, media and configuration flexibility, and optimum bandwidth utilization with minimum overhead, implement the DEFPA-DB adapters.
