反射式內存節點卡提供了一個高速、低延遲、確定性接口，允許在多達256個獨立系統（節點）之間以高達170 Mbyte/s的速率共享數據。每個反射式內存板可配置64 Mbyte或128 Mbyte板載SDRAM。本地SDRAM提供對存儲數據的快速讀取訪問時間。寫操作存儲在本地SDRAM中，并通過高速光纖數據路徑廣播到其他反射內存節點。節點之間的數據傳輸是軟件透明的，因此不需要I/O開銷。在峰值數據速率期間發送和接收FIFO緩沖區數據，以優化處理器和總線性能，保持高數據吞吐量。

Overview

The VME-5565 Reflective Memory node card provides a high-speed, low latency, deterministic interface that allows data to be shared between up to 256 independent systems (nodes) at rates up to 170 Mbyte/s. Each Reflective Memory board can be configured with either 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 processor and bus performance to maintain high data throughput.
    Network transfer rate of 43 Mbyte/s (4 byte packets) to 170 Mbyte/s (64 byte packets)
    Dynamic packet size, 4 to 64 bytes of data
    Up to 256 nodes
    Connection with multimode fiber up to 300m, single-mode fiber up to 10km
    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)
    VME transfer rate 40 Mbytes
    64 Mbyte or 128 Mbyte SDRAM Reflective Memory
