SGI 2月底在美国宣布推出两种新款 SGIOrigin200服务器:Origin200 GIGAchannel 与Origin200 Qc。这两款 Origin200服务器采用支持 cache 一致性的非均匀存储器访问体系结构(CC-NUMA),以非常低廉的价格实现对大量数据的传送与管理。新款 Origin200服务器采用同步 cache 设计方案,其 cache 的访问速度与处理器的速度相同,比以前型号的 cache 速度提高了50％。此外,SGI 还将其旗舰产品 Origin2000上采用的I/O 子系统技术——XIO 应用于 Origin200 GIGAchannel 服务器之中,大大提高了 Origin200服务器的 I/O 带宽,其实现 I/O 带宽能够达到前所未有的千兆字节,秒数量级。Origin200 GIGAchnnel 服务器尤其适用于I/O 密集型的应用领域,该领域要求高的带宽/处理器性能比值,并且可以扩展支持四个处理器。在实际应用中,Origin200 GIGAchannele服务器的 I/O 带宽可以达到1.15GB/s(相当于同档 UNIX 服务器吞吐量的三到六倍),并且显著提高了存储能力,能够快捷地响应来自更
SGI announced two new SGIOrigin200 servers in the United States by the end of February: Origin200 GIGAchannel and Origin200 Qc. Both Origin200 servers feature a non-uniform memory access architecture (CC-NUMA) that supports cache coherency, delivering and managing large volumes of data at a fraction of the cost. The new Origin200 server with synchronous cache design, the cache access speed and the same processor speed, cache speed than the previous model increased by 50%. In addition, SGI has also applied the XIO, an I / O subsystem technology introduced in its flagship product, Origin2000, to the Origin200 GIGAchannel server, greatly improving the I / O bandwidth of the Origin200 server and enabling I / O bandwidth to reach an unprecedented level Gigabytes, seconds orders of magnitude. The Origin200 GIGAchnnel server is especially suited for I / O-intensive applications where high bandwidth / processor performance ratios are required and can scale to four processors. In practical use, the Origin200 GIGAchannele server can achieve I / O bandwidth of 1.15GB / s (three to six times the throughput of comparable UNIX servers) and significantly improve storage capacity to respond quickly and efficiently
