DELL MD3000环境下配SQL SERVER 集群
SQL Server 数据库集群

SQL Server 数据库集群关键字: sql server 数据库集群先引用几段文章:1.数据库集群的作用:理想的数据库集群应该可以做到以下几点:◆在需要更高数据库处理速度的时候,我们只需简单增加数据库服务器就可以了。
这样可以大大减小硬件投资的风险,而且大大提高现有服务的质量。
◆在任何时刻需要有多个随时可用的实时同步数据服务。
为了防灾,最好有多个异地的同步数据服务。
这不光会大大增加数据可用性,还会有意想不到的更高数据库处理速度的效益。
◆除了密码保护之外,我们最好能控制企业内部对数据库的非法访问。
◆数据集的可扩性可能是最简单的要求了。
但是,用增加数据库服务器的办法来扩大数据集对数据可用性会产生负面影响。
如果没有数据冗余,那么每增加一台服务器,整个系统的可用性就会成倍地降低。
最好的结果是我们能任意增大数据集而没有对可用性的负面影响。
2.MSCS作用:MSCS解决方案可以采用主动/被动模式工作。
在同一时间集群中只有一个节点是主动的,主动服务器存储着集群内的全部资源,并不断将数据写入共享硬盘,这就是所谓的quorum驱动器。
它可以在故障恢复时,将共享状态信息从一个节点转移到另一个节点。
定时的发送信号会通过服务器间的专用网传递,当处于被动模式的服务器没有受到这个信号,就认为主动服务器已经失效。
此时,它便开始接管集群资源,并从quorum分区上读取状态信息。
3.软件实现SQL Server 2005的负载均衡中间层实现数据库的负载均衡技术,首先要有一个可以控制连接数据库的控制端。
在这里,它截断了数据库和程序的直接连接,由所有的程序来访问这个中间层,然后再由中间层来访问数据库。
这样,我们就可以具体控制访问某个数据库了,然后还可以根据数据库的当前负载来调整每次连接到哪个数据库。
好处在两个方面:首先,它成功地将数据库放到了内网之中,更好地保护了数据库的安全性。
如果数据库也在公网上,1433端口是很容易被攻击的,所以要保护数据库与之的连接,就用到了中间层。
sqlserver群集使用多磁盘的配置方法(原创,详细截图步骤)

配置SQL Server群集使用多个磁盘问题现象:软件环境:Windows2003 32bit+SQL Server2000 sp4。
当配置SQL Server备份时,无法选择群集中配置其它磁盘。
1.群集的其中一个节点有多个磁盘2.群集管理器可以观察到,有多个磁盘是共享磁盘,并已经添加到群集组中3.备份数据库,选择备份路径时,只能选择一个磁盘。
本例中E、F、盘均看不到,只有G盘可以识别。
问题原因:此问题的原因是在群集中,只有G盘与SQL Server配置了依存关系。
查看SQL Server依存关系的方式是:1.打开群集管理器,选择“群集组”中的“SQL Server”。
2.右键“SQL Server”,选择SQL Server的属性,选择“依存”选项卡解决方法及步骤:1.在“企业管理器”中关闭SQL Server服务。
2.在群集管理器中,打开SQL Server的依存关系,点击“修改”,将需要的磁盘加入到资源依存中。
3.添加完成后,重新启动SQL Server4.再次做备份时,即可使用已经建立依存的磁盘了。

Dell PowerVault MD3000i 配置指南说明书

Dell PowerVault MD3000iConfiguration Guide for VMware ESX Server SoftwareJanuary 2008Dell Virtualization Solutions Engineering/vmwareTable of Contents1. Introduction (3)2. Architectural Setup (3)3. iSCSI Connectivity Support (4)4. PowerVault MD3000i Storage Setup and Configuration (4)5. iSCSI Software Initiator Configuration on ESX Server (5)6. Configure iSCSI storage on ESX Server (8)7. References (9)Dell Inc Page 31.IntroductionThe Dell ™PowerVault ™ MD3000i storage solution consists of a standard or high availability configuration. The standard model has a single controller with two 1GbE ports. It can be deployed to support up to 16 hosts non-redundantly. The high availability model has dual controllers with two 1GbE ports per controller for a total of four 1GbE ports. The dual controller option can connect up to 16 fully redundant hosts. This document provides instructions to setup the MD3000i iSCSI storage solution for usage with VMware® ESX Server ™ software.The Dell PowerVault MD3000i iSCSI storage array contains four Ethernet ports through which the VD can be accessed affording both redundancy and availability of data. Provisioning of storage on servers in a VM environment is a multiple step process starting with definition of the server names for host access. The iSCSI connection is then established from the storage subsystem, and after detection and configuration is established as a two way link with the associated ESX server(s), completing the iSCSI communication subsystem. The final step allocates the detected storage to the individual virtual machines (VM’s), where all or part of the configured storage can be assigned to individual VM’s.2. Architectural SetupThe following figure illustrates a typical high availability setup for using the MD3000i in an ESX Server farm. As a best practice, Dell recommends using a separate Gigabit Ethernet network switch to handle iSCSI storage traffic. Two servers are connected to two switches. Each switch has a path to the MD3000i via the two dual port controllers. In this base HA configuration, the servers, switches, and MD3000i ports share the same subnet. The NIC ports serving iSCSI traffic on the ESX servers are teamed.Figure 1: MD3000i High Availability ConfigurationLANESX Server 1MD3000iESX Server 2MD1000MD1000Ethernet Switches3.iSCSI Connectivity SupportOperating System Host Bus AdapterVMware ESX Server 3.5 iSCSI software initiator with ESX Server 4.PowerVault MD3000i Storage Setup and Configuration Create virtual disks on MD3000i using steps described in:/support/edocs/systems/md3000i/en/IG/PDF/IGbk0HR.pdf.After opening the Modular Disk Storage Manager and selecting the MD3000i storage array to be configured, select the Configure tab.Note: in the examples to follow the Storage array “sg23_training” is an MD3000i withvirtual disks already configured using the Create Virtual Disks selection. The new server being added to an existing host group is named “Valhalla”.From the Configure tab1. Select Configure Host Access (Manual).2. Enter the host name for the server which has the ESX Server software is installed.3. Select Linux as the host type.From the next screen, specify the iSCSI Initiator by selecting the New button (lower right on screen). On the Enter New iSCSI Initiator screen enter a name for the iSCSI initiator name. The label is auto-populated from the server name.Figure 2: iSCSI Initiator WindowHost Group configuratio n starts from the following screen titled “Configure Host Access (Manual) –Specify Host Group”. For ESX servers supporting VMotion, HA, and DRS, a host group must be defined so the MD3000i storage subsystem has a configured iSCSI path to each of the hosts.Select “Yes: This host will share access to the same virtual disks with other hosts”If a new host group is desired select the radio button for that option and enter in a namefor your host group using standard host naming conventions (e.g. no spaces etc).Should you already have one or more host groups assigned, select the radio buttonenabling selection from a drop down list of existing host groups. This option is to beused when configuring the second, third, etc. host in a group. Once the host group isselected previously configured hosts for that host group will be displayed. Note thatthese are shown as Linux hosts even though they are configured as ESX servers. Selecting Next provides a Confirmation screen in which the new server being configured is shown and the other previously configured associated hosts are named. For the first server configured in a new host group there will be no associated hosts listed under the Associated host group.Figure 3: Modular Disk Storage Manager Configure TabSelect Finish confirming the new host definition. This initiates the wizard configuration of the new host.On completion,Select Yes to proceed to the next host you wish to configure, orSelect No to end the configuration wizard.Helpful Hint: Record the MD3000i IP address for later configuration5.iSCSI Software Initiator Configuration on ESX ServerThis section lists the steps required to configure the software initiator on the VMware ESX Server.

广电行业双机实例推荐

广电行业双机实例方案推荐北京蓝科技泰达科技有限公司2008-6-13 项目概况双机系统项目名称:上海广电忠麟电子企业有限公司项目负责人:郁卫涛陈长发用户评价:非常满意(客户调查表)案例描述:上广电双机系统采用DELL 1950服务器DELL MD3000 磁盘阵列,构建双机系统。
并使用PlusWell 软件中双激活(Active/Active)模式运行,即服务器A运行Oracle ,服务器B运行SQL Server。
Active/Active这种方式的主备机平时各自有一种应用运行,当系统中的任何一台主机出现故障,应用都会集中到一台服务器上运行,此时这台备用服务器不仅要承担以前的程序运行而且还要运行宕机服务器上的应用程序,所以此时备机的负担会加重。
这种方式的故障切换往往会造成备机访问量增大,系统运行变慢。
此方式主要适合用户有不只一种应用,用户主备机配置一样且数据访问量不大的情况。
实施方案:上广电采用双A 方式,需要对MD3000 进行两次卷的设置,并针对Oracle 与SQL 分别部署在这两个卷中,互不干预。
A、规划服务器IP地址、服务器计算机名称。
B、完成服务器上架工作,并确保服务器与各个外设的连接无误。
C、安装软件部分进行操作系统的安装、升级补丁包的安装,按照所申请的IP地址与主机名配置。
D、在每服务器安装数据库与应用系统。
数据库需按双机模式安装E、完成以上工作大概需6小时,因服务器上架时间不能确定,最终时间有可能会延长或缩短。
F、安装 PlusWell v8.0 双机热备软件。
G、设置PlusWell 系统守护进程。
(设置方法见PlusWell v8.0双机热备软件使用手册)双机热备软件安装与调试需要1-2小时H、数据库与应用系统的数据的导出、导入操作(耗时根据实际情况定)上海广电忠麟电子企业有限公司双机系统实际运行情况:在生产环境中,该项目截止到今日双机系统运行正常稳定,能够很好的完成双机系统的资源检测与接管恢复功能。

Choosing the correct solution architecture requires balancing the application’s intended purpose and expected use with the hardware platform’s components. Poor planning, bad design, and misconfigured or improperly sized hardware often lead to increased costs, increased risks and, even worse, unsuccessful projects.This white paper provides guidelines to achieve a compact, balanced, optimized 12TB Microsoft® SQL Server® 2012 data warehouse configuration for Dell™PowerEdge™ R720 and R720xd servers using Microsoft Fast Track Data Warehouse (FTDW) principles. Benefits of implementing this reference architecture include:∙Achieve a balanced and optimized system at all levels of the stack by following hardware and software best practices.∙Avoid over-provisioning hardware resources to reduce costs.∙Implement a tested and validated configuration with proven methodologies and performance behaviors to help avoid the pitfalls of improperly designed and configured systems.∙Easily migrate from a small- to medium-sized data warehouse configuration (5TB) to a large data warehouse configuration (12TB).Data center space comes at a premium. This configuration provides a compact, high-performance solution for large data warehouses with 12TB of data or more.FTDW Reference Architectures Using PowerEdge R720xd Server The Microsoft FTDW reference architecture achieves an efficient resource balance between SQL Server data processing capability and realized component hardware throughput to take advantage of improved out-of-the-box performance.As most data warehouse queries scan large volumes of data, FTDW system design and configuration are optimized for sequential reads and are based on concurrent query workloads. Understanding performance and maintaining a balanced configuration helps reduce costs by avoiding over provisioning of components.Dell provides various Fast Track reference architectures for SQL 2012 built using the Dell PowerEdge12th Generation servers. These solutions are differentiated depending on the data warehouse capacity and scan rate requirements. Table 1 summarizes FTDW configurations with Dell R720XD server.Table 1: Dell Fast Track Reference Architectures for PowerEdge R720xd ServerThe 12TB R720XD configuration described in this white paper is also available as a rapid deployment, with hardware, software, and services included in the Dell™ Quickstart Data Warehouse Appliance 2000 (QSDW 2000). This configuration provides a low-cost and easier migration path for customers who wantto go from a 5TB to 12TB solution. For more information on Dell QSDW 2000, see Dell Quickstart Data Warehouse Appliance.12TB Dell R720XD FTDW Reference ArchitectureThe following sections of this paper describe the hardware, software, capacity, and performance characteristics of a 12TB Microsoft SQL Server 2012 FTDW solution with scan rates of about 2GBps using PowerEdge R720XD servers.Hardware ComponentsRedundant and robust tests have been conducted on PowerEdge servers to determine best practices and guidelines for building a balanced FTDW system. Table 2 provides the detailed hardware configuration of the reference architecture.Figure 1: Proposed Dell Fast Track Reference ArchitectureTested Dell Fast Track Reference Architecture Component DetailsTable 2: Tested Dell FTDW Reference Architecture ComponentsPowerEdge R720xd ServerThe PowerEdge R720xd server is a two-socket, 2U high-capacity, multi-purpose rack server offering an excellent balance of internal storage, redundancy, and value in a compact chassis. For technical specifications of the R720xd server, see the Power Edge R720xd Technical Guide.ProcessorsThe Fast Track Data Warehouse Reference Guide for SQL Server 2012 describes how to achieve a balance between components such as storage, memory, and processors. To balance available internal storage and memory for the PowerEdge R720xd, the architecture uses two Intel Xeon E5-2643 four-core processors operating at 3.3GHz.MemoryFor SQL Server 2012 reference architectures, Microsoft recommends using 128GB to 256GB of memory for dual-socket configuration. Selection of memory DIMMS will also play a critical role in the performance of the entire stack.This configuration was tested with various memory sizes running at different speeds—for example,192GB running at 1333MHz, 192GB running at 1600MHz, 112GB running at 1600MHz, and so on. Using DIMMs with memory rate of 1600MHz showed significant performance improvement (about 400MBs/s) over DIMMS with memory rate of 1333MHz. In the test configuration, the database server is configured with 128GB of RAM running at 1600 MHz to which create a well-balanced configuration.To achieve 128GB of RAM on the PowerEdge R720xd server, place eight 16GB RDIMMS in slots A1-A4 and B1-B4 (white connectors). See Figure 2: Memory Slot LocationsFigure 2 for memory slot locations.Figure 2: Memory Slot LocationsInternal Storage Controller (PERC H710P Mini) SettingsThe Dell PERC H710P Mini is an enterprise-level RAID controller that provides disk management capabilities, high availability, and security features in addition to improved performance of up to6GB/s throughput. Figure 3 shows the management console accessible through the BIOS utility.Figure 3: Virtual Disk SettingsStripe element sizeBy default, the PERC H710P Mini creates virtual disks with a segment size of 64KB. For most workloads, the 64KB default size provides an adequate stripe element size.Read policyThe default setting for the read policy on the PERC H710P Mini is “adaptive read ahead.” This configuration was tested with “adaptive read ahead,” “No read ahead,”and “Read Ahead” settings.During testing, it was observed that the default setting of “adaptive read ahead” gave the best performance.Figure 4: Internal Storage Controller SettingsRAID configurationWhen deploying a new storage solution, selecting the appropriate RAID level is a critical decision that impacts application performance. The FTDW configuration proposed in this paper uses RAID 1 disk groups for database data files and database log files, nine RAID 1 data disk groups, and one RAID 1 log disk group, each created with a single virtual disk. Additionally, two drives in RAID 0 are assigned as a staging area. Figure 5 shows the proposed RAID configuration.Figure 5: RAID ConfigurationRAID 1 Data 5RAID 1Data 6RAID 1Data 7RAID 0StageRAID 1LogsRear Bay DrivesDrive slot configuration:∙Slots 0-17: Nine RAID 1 disk groups were created, each configured with a single virtual disk dedicated for the primary user data∙Slots 18-19: One RAID 1 disk group created from two disks and a single virtual disk dedicated tohost the database log files∙Slots 20-21: RAID 0 disk group created from two disks dedicated for staging∙Slots 22-23: Remaining two disks assigned as global hot spares∙Slots 24-25 (rear bay drives): One RAID 1 disk group for operating systemFor FTDW architectures, it is recommended to use mount-point rather than drive letters for storage access. It is also important to assign the appropriate virtual disk and mount-point names to theconfiguration to simplify troubleshooting and performance analysis. Mount-point names should be assigned in such a way that the logical file system reflects the underlying physical storage enclosure mapping. Table 3 shows the virtual disk and mount-point names used for the specific reference configuration and the appropriate storage layer mapping. All of the logical volumes are mounted to the C:\FT folder.Table 3: Mount Point Naming and Storage Enclosure MappingFigure 6 represents the storage system configuration for the proposed FTDW reference architecture.Figure 6: Storage System ComponentsThe production, staging, and system temp databases are deployed per the recommendations provided in the Fast Track Data Warehouse Reference Guide for SQL Server 2012.Application ConfigurationThe following sections explain the settings applied to operating system and database layers.Windows Server 2008 R2 SP1Enable Lock Pages In Memory to prevent the system from paging memory to disk. For more information, see How to: Enable the Lock Pages in Memory Option.SQL Server ConfigurationThe following startup options were added to the SQL Server Startup options:∙-E: This parameter increases the number of contiguous extends that are allocated to a database table in each file as it grows to improve sequential access.∙-T1117: This trace flag ensures the even growth of all files in a file group when auto growth is enabled. It should be noted that the FTDW reference guidelines recommend pre-allocating the data file space rather than allowing auto-grow.SQL Server Maximum Memory: FTDW for SQL Server 2012 guidelines suggest allocating no more than 92% of total server RAM to SQL Server. If additional applications will share the server, then adjust the amount of RAM left available to the operating system accordingly. For this reference architecture, the maximum server memory was set at 119808 MB (117GB).Resource Governor:For SQL Server 2012, Resource Governor provides a maximum of 25% of SQL Server memory resources to each session. The Resource Governor setting can be used to reduce the maximum memory consumed per query. While it can be beneficial for many data warehouse workloads to limit the amount of system resources available to an individual session, this is best measured through analysis of concurrent query workloads. This configuration was tested with both 25% and 19% memory grant, and the 25% setting was found to be optimal for the proposed configuration. For more information, see Using the Resource Governor.Max Degree of Parallelism: The SQL Server configuration option Max degree of parallelism controls the number of processors used for the parallel execution of a query. For the configuration, settings of 12 and 0 were tested. The default setting of 0 provided maximum performance benefits. For more information, see Maximum degree of parallelism configuration option.Capacity DetailsTable 4Table 4 shows the capacity metrics reported for the recommended reference configuration.Table 4: Capacity MetricsPerformance BenchmarkingMicrosoft FTDW guidelines help to achieve optimized database architecture with balanced CPU and storage bandwidth. Table 5 shows the performance numbers reported for the recommended reference configuration.Table 5: Performance MetricsThe following sections describe the detailed performance characterization activities carried out for the validated Dell Microsoft FTDW reference architecture.Baseline Hardware Characterization Using Synthetic I/OThe goal of hardware validation is to determine actual baseline performance characteristics of key hardware components in the database stack to ensure that system performance is not bottlenecked in intermediate layers.The disk characterization tool, SQLIO, was used to validate the configuration. The results in Figure 7 show the maximum baseline that the system can achieve from a cache (called Line Rate). A small file is placed on the storage, and large sequential reads are issued against it with SQLIO. This test verifies the maximum bandwidth available in the system to ensure no bottlenecks are within the data path.Figure 7: SQLIO Line Rate Test from Cache (Small 5MB File)PERC H710P Mini ControllerSynthetic I/O rate: 2674 MB/sThe second synthetic I/O test with SQLIO was performed with a large file to ensure reads are serviced from the storage system hard drives instead of from cache. Figure 8 shows the maximum real rate that the system is able to provide with sequential reads.Figure 8: SQLIO Real Rate Test from Disk (Large 25GB File)PERC H710P Mini ControllerSynthetic I/O rate: 2616 MB/sFTDW Database ValidationThe performance of a FTDW database configuration is measured using two core metrics: Maximum CPU Consumption Rate (MCR) and Benchmark Consumption Rate (BCR).MCR - MCR indicates the per-core I/O throughput in MB or GB per second. This is measured by executing a pre-defined query against the data in the buffer cache, and then measuring thetime taken to execute the query against the amount of data processed in MB or GB. For thevalidated configuration with two Intel E5-2643 four-core processors, the system aggregate MCR was 2488 MB/s. The realized MCR value per core was 311 MB/s.BCR - BCR is calculated in terms of total read bandwidth from the storage hard drives—not from the buffered cache as in the MCR calculation. This is measured by running a set ofstandard queries specific to the data warehouse workload. The queries range from I/Ointensive to CPU and memory intensive, and provide a reference to compare variousconfigurations. For the validated FTDW configuration, the aggregate BCR was 1909 MB/s.During the evaluation cycle, the system configuration was analyzed for multiple query variants (simple, average, and complex) with multiple sessions and different degrees of parallelism(MAXDOP) options to arrive at the optimal configuration. The evaluation results at each stepwere validated and verified jointly by Dell and Microsoft.FTDW Database Validation with Column Store Index (CSI)SQL Server 2012 implements CSI technology as a nonclustered indexing option for pre-existing tables. Significant performance gains are often achieved when CSI query plans are active, and this performance can be viewed as incremental to the basic system design.After the test configuration was validated, CSI was added. Then, the same set of I/O and CPU-intensive queries were executed to compare throughput achieved using CSI. Throughput rating of 4337.5 MB/s was achieved for CSI-enhanced benchmarks. These numbers can be used to approximate the positive impact to query performance expected under a concurrent query workload.ConclusionThe Dell Microsoft FTDW architecture provides a uniquely well-balanced data warehouse solution. By following best practices at all stack layers, a balanced data warehouse environment can be achieved with a greater performance benefits than traditional data warehouse systems.ReferencesDell SQL Server Solutions\sqlDell Services\servicesDell Support\supportMicrosoft Fast Track Data Warehouse and Configuration Guide Information /fasttrackAn Introduction to Fast Track Data Warehouse Architectures/en-us/library/dd459146.aspxHow to: Enable the Lock Pages in Memory Option/fwlink/?LinkId=141863SQL Server Performance Tuning & Trace Flags/kb/920093Using the Resource Governor/en-us/library/ee151608.aspxMaximum degree of parallelism configuration option/kb/2023536Power Edge R720xd Technical Guide/support/edocs/systems/per720/en/index.htm。
