Brocade 300是一款24端口交换机，可为入门级SAN奠定经济而灵活的基础，也可在核心到边缘SAN环境中用作边缘交换机。它可以在高能效、经过优化的1U机型中提供8 Gbps的性能，来支持最苛刻的服务器和虚拟服务器部署。


1.概述


Brocade 300是一款吞吐量达8 Gbit/秒的光纤通道交换机，是专为小型SAN或大型SAN边缘设计的经济型入门级解决方案。它使中小型企业可以简化IT基础设施，提高系统性能，最大限度地发挥虚拟服务器部署的价值并降低总体存储成本。


经济合算的SAN技术


Brocade 300能够以入门级解决方案的价格提高卓越的性能和强大的功能。它将1、2、4和8 Gbit/秒的光纤通道吞吐量自动侦测与旨在增强光纤架构性能的功能结合在一起。Brocade 300能够提供如此强大的功能，而每端口的功耗还不到2.5瓦，因此，具有出色的功率和冷却效率。


Brocade 300采用了一种无阻塞架构，最多支持24个端口同时以8 Gbit/秒（全双工）的速率运行，并且不会出现超量使用现象——总带宽为192 GB/秒。另外，增强的Brocade ISL干线合并还可以支持最高吞吐量达64 GB/秒的单一逻辑高速干线。


简化的管理


借助Brocade EZSwitchSetup安装向导，可以轻松便捷地安装和配置Brocade 300，交换机的配置、部署和管理变成了简单的三步点击操作。在多交换机环境中，博科网络顾问软件（Brocade Network Advisor）可提供全面的数据中心Fabric架构管理功能，包括博科骨干网、交换机和适配器的配置、监控和管理。Brocade 300 可兼容Microsoft Simple SAN，另外还带有一个可通过简化固件升级和系统日志文件下载来提高维护简便性和错误记录的USB端口。


简单快捷的扩展


Brocade 300易于部署和管理，并且可以轻松集成到新的和现有的IT环境中。Brocade 300具有按需端口扩展（Ports on Demand）（端口可由8个扩展至16或24个）等多种功能，因此，企业可以根据需要随时扩展自己的存储网络而不会影响业务正常运行。另外，企业可以先部署4 Gbit/秒的SFP，然后根据需要升级为8 Gbit/秒的SFP。


高级连接选项


Brocade 5100可作为一款全光纤交换机或作为一款Brocade Access Gateway（接入网关）进行部署，能提供到任一SAN网络的连接（其默认模式设置是一款交换机）。接入网关模式采用N_Port ID虚拟化（NPIV）交换机标准，可将光纤通道连接作为逻辑设备提呈到SAN Fabric架构中。如果利用支持NPIV技术的交换机和导向器进行连接，接入网关模式下的Brocade 300可以连接到Brocade、McDATA或其它SAN Fabric架构。


Brocade光收发模块


Brocade 8 Gbit/sec交换机需要Brocade光收发模块。这种模块有多种型号，可以满足不同的速度和距离要求。这些小型可插拔（SFP）模块最适合用于Brocade 8Gbit/sec产品，可以最大限度地提高性能，降低功耗，帮助确保关键任务应用的最高可用性。

行业标准遵从

Brocade产品符合行业标准，而且采用了普遍接受的工程实践和流程。
