FibreAccess® Network Access Controller for Fibre Channel Applications


Part Number(s): FC-75000
Package: PMC
Lead Free Information: B

The FC-75000 FibreAccess series are dual redundant Fibre Channel Controller PMC cards optimized for use in military/aerospace applications. The FibreAccess Controller can operate at either 1 Gb/s or 2 Gb/s data rates in point-to-point, arbitrated loop or switched fabric topologies. Fibre Access cards are available with either copper or optical interfaces on a conduction or convection cooled PMC form factor.

Based on DDC's own Fibre Channel technology, FibreAccess’s architecture is optimized to meet the highly deterministic performance, high reliability, and demanding environmental requirements of embedded, real time, military applications. Its flexible FPGA-based architecture can be tailored to meet a wide range of specific system requirements. Moreover, FibreAccess is not subject to rapidly changing commercial market forces that can result in shortened life cycles. Instead, DDC's FibreAccess technology has been designed to meet the multi-decade life cycle demands of military/aerospace programs, continuing DDC’s demonstrated commitment as a long-term military COTS supplier of digital interface devices.

FibreAccess support Class 2 acknowledged and Class 3 unacknowledged Fibre Channel service. The cards provide leading edge performance which includes capability to enable sustained data rates of over 300MBytes/s when operating at a 2Gb/s data rate. The card's built-in DMA engines and 64-bit/66 Mhz PCI initiator/target interface, which operate in conjunction with the FibreAccess's Frame/Sequence/Exchange management controller, autonomously move payload data to and from PCI space. Using host initiated descriptors, frames are assembled and disassembled autonomously to and from payload buffers in host memory.

To support the unique requirements of military aerospace applications, the FibreAccess includes a number of advanced architectural features. The cards allow simultaneous processing of pre-scheduled on-card exchanges, along with high and low priority on-demand exchanges. Other features include autonomous automatic failover; implicit Fibre Channel login; Fibre Channel priority; ELS clock synchronization, and support of ASM, TCP/IP, and UDP/IP upper layer protocols. The FibreAccess is designed to operate in harsh environments at temperatures from -40 °C to +85 °C, and withstand the mechanical shock and vibration typically found in military/aerospace environments.

DDC's FibreAccess Controller is suitable for a wide variety of applications for embedded avionics and vetronics systems. These include sensor interfacing, multi-processor and DSP arrays, radar systems, display systems, serial backplanes, and storage.
