The 2Gb-enabled JNIC-1460 offers a flexible architecture that can be easily integrated into a variety of I/O applications. combines. With Full-Duplex Fibre Channel data transfer rates of up to 400 MB/s and a 64-bit, 66 MHz PCI host interface, it delivers the unparalleled I/O performance demanded by next-generation SAN appliances. This powerful ASIC integrates a wide array of advanced I/O technologies to enhance total system performance. Starting with an embedded I/O engine that performs real-time context switching to maximize SAN data throughput, the engine can queue up to 254 active exchanges on-chip. Additional active exchanges can be accommodated on the local memory port. JNIC-1460 proprietary data flow architecture allows for a very efficient, low latency data path for both receive and transmit channels. An integrated RISC-based I/O engine with large instruction RAM significantly reduces host CPU utilization while requiring less than one interrupt per I/O operation. This makes the JNIC-1460 an ideal candidate for high-end servers and external Fibre Channel storage applications.
