1.概述
面向私有云存储的灵活、简便易用的入门级SAN交换机
为满足不断增长的业务需求,数据中心正迁移到高度虚拟化的私有云存储环境。这种方法使企业可以整合并简化IT资源,进而提高业务灵活性并降低资本支出和运营支出。但伴随虚拟化而来的还有一系列挑战。数据中心必须适应爆炸性数据增长和虚拟化工作负载带来的动态变化。要实现这些基于云的架构的全部优势,选择适当的网络是关键。
采用Gen 5 Fibre Channel(16 Gbps)技术的Brocade 6505交换机可提供超高的性价比,将出色的灵活性、简便性和企业级功能无缝地结合到一台入门级交换机中。Brocade 6505设计用于实现最高的灵活性和可靠性,有12或24端口两种配置,而且可在高效的1U包装中支持2、4、8或16 Gbps的速度。它标配有带集成风扇的单一电源。可选的第2套电源可提供更高的冗余,来确保更高的弹性。
简化的部署流程和点击式用户界面使Brocade 6505更加强大而且简便易用。此外,Brocade 6505可帮助以很低的成本获得行业领先的Gen 5 Fibre Channel技术的优势,同时提供“边增长边付费”式可扩展性,来满足不断发展演进的存储环境的各种需求。其它主要特性包括:
提供超高的性价比,在24端口1U高入门级交换机中结合出色的灵活性、简便性和企业级功能
利用按需端口扩展(PoD)功能,快速、简单而经济高效地从12个端口扩展到24个
利用平滑的软件升级和可选的冗余电源最大限度地提高弹性
利用Brocade EZSwitchSetup向导简化部署
借助动态Fabric配置、关键性能监控和高级诊断特性简化部署和故障排除,缩短时间
提供双重功能,既可用作功能全面的Fabric SAN交换机,又可用作支持NPIV的Brocade Access Gateway,进而简化服务器连接,提高SAN可扩展性
通过Brocade Network Advisor简化并集中进行管理,降低运营成本和复杂性
2.特性
超高的性价比,支持不断增长的SAN工作负载
Brocade 6505集市场领先的吞吐量和经济的交换机外形设计于一身,是应对不断增长的SAN工作负载的理想选择。24个端口可提供总共384 Gbps的全双工吞吐量;可将任意8个端口捆绑起来,形成128 Gbps的互联链路捆绑(Inter-Switch Link,ISL)。基于交换的动态路径选择(DPS)可以优化全Fabric架构的性能,并通过自动将数据路由到Fabric架构内最高效的空闲路径上来实现负载均衡。它可以进一步补充Brocade ISL链路捆绑,在特定配置中提供更有效的负载均衡。
此外,Brocade 6505的总体拥有成本(TCO)很低,因为它的12端口基本配置易于管理,只占用1U的机架空间而且能耗很低——每Gbps为0.22瓦,每端口为3.3瓦。企业级功能与很低的TCO相结合,与成本相当的同类其它万兆以太网(10 GbE)解决方案相比可提供高40%的性能。
行业领先的技术,灵活、简单而且简便易用
Brocade 6505在灵活、简单而且简便易用的解决方案中提供行业领先的Gen 5 Fibre Channel技术。基本配置包含12个端口,可根据需要最多扩展到24个端口。除了提供最高的可扩展性之外,Brocade 6505还可以通过Brocade EZSwitchSetup向导和可简化设置的全新“D_Port”特性来实现轻松部署。
虚拟化私有云存储的有机组成部分
Brocade 6505为当前高度虚拟化的私有云存储环境提供了一个关键组件。它可以简化服务器虚拟化和虚拟桌面基础架构(VDI)管理,同时满足固态硬盘(SSD)的高吞吐量需求。Brocade 6505还可以通过服务质量(QoS)和基于Fabric架构的分区特性来在云环境中支持多租户(multi-tenancy)。
Brocade Access Gateway模式
Brocade 6505可作为功能全面的Fabric架构交换机或作为Brocade Access Gateway(接入网关)进行部署,来简化Fabric架构拓扑和异构Fabric架构连接(其默认模式设置是交换机)。Brocade Access Gateway模式利用N_Port ID Virtualization(NPIV)交换机标准来直接向SAN Fabric架构的核心显示物理和虚拟服务器。这使Brocade Access Gateway对SAN Fabric架构完全透明,因此可大大减轻网络边缘的管理工作。以Brocade Access Gateway模式*运行的Brocade 6505可以将服务器连接到支持NPIV的Brocade B系列、Brocade M系列或其它SAN Fabric架构。
企业可以通过Brocade Network Advisor(博科网络顾问软件)或CLI轻松实现Brocade Access Gateway模式。Brocade Access Gateway模式的主要优势包括:
更高的可扩展性,适合大型或快速增长的服务器和虚拟服务器环境
减少网络边缘的管理工作,因为Brocade Access Gateway没有域身份,在核心Fabric架构看来是完全透明的
支持异构SAN配置,而不减少服务器连接功能
在入门级交换机中提供企业级特性
Brocade 6505在入门级交换机中提供先进的监控、诊断、RAS和冗余功能,来最大限度地提高可用性,优化性能并简化管理。这些企业级特性包括:
关键的诊断和监控功能,可帮助确保尽早完成故障检测和恢复
在每个端口上支持平滑、非破坏性监控,提供整个Fabric架构的端到端视图
前向纠错(FEC)可从ISL中的位错误中恢复,进而增强传输可靠性和性能
额外的缓冲器,可避免缓冲信用丢失导致的性能降低和拥塞
在ISL上根据主机/应用进行实时带宽消耗量计算,识别热点和潜在的网络拥塞
可选的第2套电源,实现双电源冗余,增强可用性
Brocade 6505的Brocade Access Gateway模式仅在24端口配置中受支持。
