EMC Symmetrix 系列-比较数据

EMC SYMMETRIX VMAX 存储系统EMC® Virtual Matrix Architecture™是一种构建存储系统的新方法，可通过称为 EMC Symmetrix®VMAX™引擎的通用构造块扩展系统资源，从而超越所有现有体系结构的物理约束。

单个 VMAX 引擎即可为高可用性 Symmetrix VMAX 系统奠定完整的基础。

每个 VMAX 引擎包含两个 Symmetrix VMAX 控制器和用于连接到 EMC Virtual Matrix™互连的冗余接口。

每个Symmetrix VMAX 控制器整合了前端、全局内存和后端功能，支持对数据进行直接内存访问以优化 I/O 操作。

VMAX 引擎通过一组（包括多个）提供可扩展性能和高可用性的活动结构互连在一起。

可以无中断地添加 VMAX 引擎，以线性横向扩展 Symmetrix 系统资源。

Virtual Matrix 设计为可扩展到数十个引擎，这些引擎可分散于整个数据中心内，可通过单点管理提供前所未有的基础架构服务级别。

VMAX 引擎最大规格• 四个四核 2.33 GHz Intel® Xeon®处理器• 最高 128 GB 内存• Virtual Matrix 带宽：24 GB/sVMAX 最大系统规格• 八个 VMAX 引擎• 1 TB 内存• Virtual Matrix 带宽：192 GB/sVMAX 互连• 行业标准 RapidIO®结构（Virtual Matrix Architecture 可扩展到其他标准互连。

）连接Symmetrix VMAX 系统可以采用最多支持八个 VMAX 引擎的配置，最多可以包含 128 个前端端口。

优化的硬件逻辑和数据保护编码通过通道自动故障切换确保端到端的数据完整性，最大限度地实现了可用性和负载平衡。

Symmetrix VMAX 系统支持所有常用的硬件和操作系统平台、存储区域网络 (SAN) 和高可用性群集环境。

存储产品：三大系列低端：celerra系列对应容灾产品：Celerra Replicator中端：CLARIION价格十几万到几十万对应容灾产品：mirrorview（磁盘到磁盘的复制，可以做一对多的复制）snapview（基于快照、克隆的数据备份）Mirrorview可以做一个存储到两个备份存储的数据复制高端：symmetrix价格几十万到上百万对应容灾产品：Symmetrix SRDF（类似mirrorview，可做远程和本地的）timefinder（类似snapview）这些容灾功能都是在存储内部本身已经集成的，每个产品对应的各自的系列容灾产品mirrorview、Symmetrix SRDF是存储到存储的数据复制，要求两边的存储要是同一个系列的。

snapview、timefinder是存储到存储内部本身的数据备份备份容灾软件：networker：实现数据集中备份的软件，可以对多种不同数据库进行备份（类似我们的服务器备份）RecoverPoint、RecoverPoint/SE：也是存储到存储的数据复制，其中RecoverPoint/SE是专门针对CLARIION系列存储的这个软件做本地和异地的都可以的，可以一对一，可以一对多，可以本存储到本存储，也可以本存储到另一个存储RecoverPoint是独立的软件，可以针对布什EMC的存储设备去做数据复制Avamar：重复数据删除软件，EMC自己的Homebase：数据恢复和迁移功能的软件容灾备份硬件Data Domain ：Data Domain是被EMC收购的公司具有重复数据删除功能的备份存储设备，与上面的三个系列的存储不一样，是专门用来存备份的数据的，其重复数据删除功能与avamar相似Avamar，Data Domain 功能类似，大都与networker想结合使用Data library虚拟带库设备EMC做容灾备份没有单独一个软件就能实现所有功能的，一般都是几个产品组合成一整套的解决方案，价格都是比较高的。

EMC SYMMETRIX VMAX 10KEMC ® Symmetrix ® VMAX ® 10K 与 Enginuity™ 操作环境相结合，为企业提供真正的第 1 层多控制器、具备整合能力和高效率的横向扩展体系结构。

VMAX 10K 采用了与 VMAX 20K 和 VMAX 40K 系统相同的革命性的 EMC Virtual Matrix Architecture 。

规格体系结构Virtual Matrix Architecture 使 IT 部门能够构建超越竞争对手阵列体系结构物理限制的存储系统。

这种体系结构允许通过被称为 VMAX 10K 引擎的通用且完全冗余的构造块来扩展系统资源。

单个 VMAX 10K 引擎即可为高可用性存储阵列奠定完整的基础。

每个引擎包含两个 VMAX 10K 控制器和多个用于实现与 EMC Virtual Matrix 互连的冗余接口。

每个控制器整合了前端、全局内存和后端功能，支持对数据进行直接内存访问以优化 I/O 操作。

多达四个 VMAX 10K 引擎，可通过一组提供可扩展的性能和高可用性的活动连接结构（包括多个）互连在一起。

可以无中断地添加 VMAX 10K 引擎，以横向扩展系统资源性能。

VMAX 10K 系统支持使用 2.5 英寸驱动器、3.5 英寸驱动器或在阵列中混合使用这两种类型的驱动器。

单个系统机架承载一个引擎和最多 10 个 3.5 英寸或混合配置磁盘阵列存储模块 (DAE)，或者最多 12 个 2.5 英寸配置 DAE 。

可选存储机架（用于 3.5 英寸和混合配置阵列）承载最多 12 个 DAE 。

单引擎 VMAX 10K 最初可以只配置 24 个驱动器，以后可以纵向扩展到支持 1,560 个驱动器的四个引擎，达到 1.5 PB 的最大可用容量。

一个四引擎阵列可提供最多 512 GB 的缓存（每个引擎 128 GB ）和最多 64 个主机或复制网络端口，包括光纤通道 (FC)、iSCSI 、FCoE 和 SRDF （端口最大数量因连接类型而异）。

映射磁盘管理系列（一）Symmetrix磁盘映射工作原理介绍原文出处：EMC中文支持论坛Symmetrix映射磁盘设备管理系列主要介绍配置主机访问Symmetrix阵列的方法。

本系列共分10个章节：（一）磁盘映射工作原理（二）磁盘映射控制概述（三）磁盘映射拓扑结构（四）配置磁盘映射（五）显示主机HBA（六）添加映射磁盘设备（七）维护磁盘设备数据库（八）查看VCMDB（九）主机总线适配器(HBA)管理（十）光纤通道与主机的接口管理更多信息磁盘映射概述：SYMCLI可以用关联一个或者多个磁盘设备到Symmetrix阵列的FA前端口和主机的HBA的方式，对主机与磁盘设备映射的访问进行进行控制和分配。

VCMDB数据库作为主要存放磁盘映射信息的载体，它会对于每个Symmetrix阵列维护一个访问控制记录，从而防止多个主机对同一个磁盘设备进行读写。

这种做法叫做定义Masked Channel。

磁盘映射命令还能被用来配置多个主机访问一个FA前端口，这种方式在多类型主机的情况下很有用。

然而，用户也可以通过使用光纤ID锁定的方式来对WWN欺骗进行保护。

磁盘映射的工作原理：有些情况下，如果用户定义了Masked Channel，允许多台主机连接到某个Symmetrix的Director 上，会有潜在冲突使得多个主机同时访问和使用一同组磁盘设备。

为了避免这种情况，用户可以使用磁盘映射功能，在VCMDB中维护一组记录，来控制和维护阵列中的磁盘设备与主机之间的访问关系。

VCMDB中的记录内容包括主机的HBA标识（HBA端口和WWN），它与FA前端口和映射到FA前端口的磁盘设备关联，从而保证只有特定的HBA可以看到。

一旦用户创建了VCMDB记录然后激活配置，Symmetrix阵列，VCMDB 表明这些磁盘设备是可以通过相关的FA端口被主机的Initiator的WWN访问。

VCMDB中，每个Director 控制最多256个不同的WWN或者512个iSCSI（从Enginuity微码版本5771开始）。

EMC高端存储方案介绍第1章高端存储产品介绍1.1EMC VMAX 10K存储阵列1.1.1 SYMMETRIX VMAX简介目前，企业正在寻求方法降低成本，同时为其客户提供更高级别的服务。

服务器虚拟化正在推动向更高效数据中心的转变。

这些虚拟环境都要求更低的成本、简化的管理、更高的可扩展性、更大的灵活性，以及横向扩展存储的能力。

EMC以悠久的创新历史（包括500多项专利）为基础，通过采用Enginuity的全新Symmetrix VMAX系列推动了Symmetrix 平台的发展。

无怪乎世界各地各种规模的企业纷纷选购Symmetrix，使其在高端存储市场中的份额位居第一。

Symmetrix VMAX 系列是仅有的专为虚拟数据中心构建的存储系统，支持企业：•通过横向扩展和存储分层降低成本•为关键应用程序提供更高级别的服务•利用前所未有的性能和规模•实现无与伦比的应用程序可用性•依靠安全的信息基础架构•实现最高级别的安全性当今虚拟数据中心的存储要求Symmetrix 是元老级的存储平台，它曾让存储行业发生了革命性的变化，其非凡的表现已向世人证明，它是当之无愧的高端存储黄金标准。

它将继续领导本行业，为世界上最关键的应用程序提供高可用性、高性能的存储。

今天，Symmetrix 凭借其创新性已创建了多种行业级存储类别，如外部存储阵列、企业存储，以及本地和远程复制。

Symmetrix 还实现了多项业界第一，其中包括“机箱内”分层存储、高级多站点复制、在单个阵列中支持高达PB级的可用容量、支持第1层超高性能要求的本机企业级闪存驱动器，以及最近的子LUN针对虚拟池的全自动存储分层（FAST VP，可针对动态工作负载环境持续优化性能）。

IT 环境正在经历从物理环境到虚拟环境的过渡。

虚拟化正在数据中心中加速发展。

大多数IT企业已在归其IT 所有的应用程序（如测试、开发以及较小型数据库和应用程序）中成功部署虚拟化。

他们的下一步便是虚拟化其业务生产和第1 层应用程序，如ERP、电子邮件和客户支持应用程序。

高大上的EMC Symmetrix系列（DMX/VMAX）承担了众多的客户关键业务，但在做存储系统维护时总是提到一个动态密码或者口令的东西，外行人员对这个充满了疑惑，对采取这种动态密码机制不理解，甚至有些偏激，认为厂商设置了一些服务障碍。

本文将对动态密码（Service Credential）进行一些说明和解释，消除大家对该机制的误解。

什么是Symmetrix产品系列？很多客户听说过EMC 的DMX和VMAX产品，但是没有听说过Symmetrix，也不清楚Symmetrix和DMX以及VMAX的关系。

Symmetrix是EMC的高端存储整列统一名称，该产品系列包含不同的产品型号，如大家耳熟能详的DMX3,DMX4以及VMAX等。

类似于中端系列VNX，包含不同的产品型号，如VNX5100,5200,5400等等。

Symmetrix产品系列运行在一个叫做Enginuity的操作系统之上，不同的产品型号运行不同的Enginuity 操作系统版本，EMC叫做code。

如DMX3和4，目前的target主版本是5773，VMAX1和2代在5876，刚刚发布的VMAX3代是5977。

在主版本上，有不同的小版本。

理解了Symmetrix以及Enginuity code后，我们再来看动态密码。

什么是动态密码(Service Credential)?EMC Symmetrix的动态密码（Service Credential）是从Symmetrix 5772版本以后引入的新功能，采用RSA安全加密机制。

大家知道，RSA是目前民用的最高加密算法，基本上要破解RSA加密不太可能。

该动态密码用来防止非授权人员登录Symmetrix产品的维护工具（SymmWin），而不是我们过去的很多误解，认为是用来阻止用户对Symmetrix存储系统的访问。

SymmWin是EMC开发的专门针对Symmetrix 存储系统的维护工具，该工具为EMC专利保护，并只能由EMC的授权人员使用，并没有作为一个软件产品卖给客户。

EMC Symmetrix DMX 日常监控方法客户操作及代码说明EMC客户服务支持团队1/8/2010本文档仅供EMC客户使用，未经EMC公司授权，不得复制、转载、出版和传播EMC公司推荐客户使用EMC 远程监控及支持系统（包括call home，Webex、ESRS等多种模式），客户也可以通过本文中提及的方法，实现对EMC Symmetrix DMX系列产品的监控。

一、在主机上建立或更新存储设备信息：这个操作在监控主机上执行一次后，将会在监控主机上建立存储设备信息的数据库，以后只有在存储设备配置变更后，才需要重新执行，用来更新存储配置信息。

登录到安装有Solutions Enabler的主机，执行以下命令(需要一至二分钟)：symcfg discoverSolutions Enabler安装目录UNIX： /usr/symcli/binWindows： C:\Program Files\EMC\SYMCLI\bin二、使用以下命令列出该主机所连接的存储信息：symcfg list列出主机所连接的存储，包括local和remote，输出示例如下：S Y M M E T R I XMcode Cache Num Phys Num Symm SymmID Attachment Model Version Size (MB) Devices Devices000290xxxx26 Local DMX4 5773 65536 0 1042000290xxxx82 Remote DMX4 5773 65536 0 353三、查看存储设备的日志信息：symevent -sid <sn> -v list -start <start date> [-end <end date>]收集序列号为SN的盘阵在start date到end date之间的日志信息。

例如：symevent -sid 19 list -start 12/20/2009此命令为收集序列号尾数为19的盘阵在2009年12月20日以来的日志信息。
