小型SAN的理想之选 – 可提供最高性能、简便易用的可扩展交换机。

1.概述

Brocade 5100交换机专为迅速增长的存储环境而设计 — 在一个高效的1U机架中，可配置24、32或40个端口，结合了1、2、4和8 Gbps光纤通道技术。Brocade 5100适用于各种SAN架构，每个端口的功耗不超过2.5瓦，因此具有出色的功率和冷却效率。它还集成了电源和风扇组件，以提高环境性能，降低总拥有成本。

业界领先的性能和灵活性

为了支持关键任务环境，Brocade 5100可提供同类中端SAN交换机中最佳的性能。它采用了一种无阻塞架构，最多支持40个端口同时以8 Gbps（全双工）的速率运行，并且不会出现超量使用现象——总带宽高达320 Gbps。此外，增强型Brocade ISL干线合并使一条逻辑链路最多可提供64 Gbps的平衡数据吞吐量。

为了最大限度地发挥虚拟服务器部署的价值，Brocade 5100提供了最高用量者（Advanced Performance Monitoring的一个组成部分）和适应性网络服务—一套包括入站速率控制、流量隔离和服务质量（QoS）功能的工具。这些先进的功能可帮助优化Fabric架构的运行，确保关键任务应用可获得充足的带宽。为了进一步增强灵活性，提升价值，Brocade 5100还提供了集成路由功能，以连接不同Fabric架构中的交换机。

Brocade 5100包括一种虚拟Fabric架构特性，可将物理SAN分成多个逻辑Fabric架构。这样就可以根据应用、业务部门、客户或流量类型实现Fabric架构隔离而不会降低性能、可扩展性、安全性和可靠性。

为了使用Fibre Channel over Ethernet（FCoE）和Converged Enhanced Ethernet（CEE）整合服务器连接，Brocade 5100可与Brocade 8000架顶式交换机全面兼容。

高可用性

Brocade 5100是实现灾难恢复和业务连续性的可靠基础，带有多种企业级可用性特性，如可热插拔的冗余集成风扇和电源组件等。另外，凭借更快速的系统升级和维护优势，热代码加载和激活功能有助于最大限度地延长应用的正常运行时间。

为了支持SAN扩展，Brocade 5100允许将服务器和存储设备部署在相距3400公里的地方，进而帮助企业实施最复杂的业务连续性和灾难恢复计划。

简单快捷的扩展

Brocade 5100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 5100具有按需端口扩展（Ports on Demand）（端口可从24个扩展至32或40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，企业也可以先部署4 Gbps的SFP，然后根据需要将其升级为8 Gbps的SFP+。

简化的部署和管理

Brocade交换机借助经济高效的管理解决方案来优化存储网络资源，提高效率，同时降低拥有成本。EZSwitchSetup向导的设计目的是使部署变得更加简单。在多交换机环境中，Brocade DCFM Professional可以简化管理，并对整个Fabric架构进行监控。

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 5100可以连接到Brocade、McDATA或其它SAN Fabric架构。

Brocade光收发模块

Brocade 8Gbps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 8Gbps产品，可以最有效地提高性能，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。
