PCI-5565

PCI-5565 Reflective Memory interface allows data to be shared between up to 256 independent systems (nodes) at rates up to 174 Mbyte/s. Each Reflective Memory board may be configured with 64 Mbyte or 128 Mbyte of onboard SDRAM. The local SDRAM provides fast Read access times to stored data. Writes are stored in local SDRAM and broadcast over a high speed fiber-optic data path to other Reflective Memory nodes. The transfer of data between nodes is software transparent, so no I/O overhead is required. Transmit and Receive FIFOs buffer data during peak data rates to optimize the host computer and bus performance to maintain high data throughput.

• Network transfer rate 43 Mbyte/s (4 byte packets) to 174 Mbyte/s (64 byte packets)
• Dynamic packet size, 4 to 64 bytes of data
• Connection with multimode fiber up to 300m, single mode fiber up to 10km
• Up to 256 nodes
• Data written to memory in one node is also written to memory in all nodes on the network
• High speed, easy to use fiber-optic network (2.12 Gbaud serially)
• 64 Mbyte or 128 Mbyte SDRAM Reflective Memory
• Not recommended for new designs
