2、ally Bind LUNs.实验内容:1、Using the Storage Allocatation Wizard to assign LUNs;2、Manually Bind LUNs. 二、实验原理实验原理:RAID 是一种把多块独立的硬盘(物理硬盘)按不同的方式组合起来形成一个硬盘组(逻辑硬盘),从而提供比单个硬盘更高的存储性能与数据备份能力的技术。三、所用仪器、材料(设备名称、型号、规格等或使用软件)设备:1台PC。四、实验方法、步骤(或:程序代码或操作过程)1、Using the Storage Allocatation Wizard to assign LUNs.1)click
3、 the provision icon under the Storage Management Task bar to launch the Storage Provision Wizard. Click Next after reading the Wizard dialog. A list of available servers will be displayed.2)Read the dialog from the “Select Servers” window. Keep the “Assign LUNs to the servers” radio button selected.
4、 Click on the server w3k-240.Click Next.3)The “Select Storage System” window will display the available arrays. Highlight the cx1_prod Storage System. Click Next.4)Read the “warning: Storage provisioning Wizard” windows. Click Yes.5)Read the dialog from the “Select LUN Type” window. Keep the “Tradit
5、ional” radio button selected. Click Next.6)In the “Select Storage Pool” windows, you can create a new Storage Pool, click New Storage Pool button, Using the dropdowns, The Create Storage Pool window shown in the next screen and select Apply,in this window, you must create muti-pool ,please change th
6、e value of RAID Type and Number of Disks.7)Read the “Confirm: Create Storage Pool” dialog. Click Yes.8)Return the “Create Storage Pool” window, Click Cancel.9)Return the “Select Storage Pool” window, Highlight the ID 0 Storage pool. Click Next., The LUN Properties window shown in the next screen, En
7、ter the values shown and select Next.10)In the “select Folder” window, Then Click Next, Finish, Finish. 1)Create the following RAID Groups (without the Wizard): Right click on the RAID Group - Create RAID Group, Use the following parameters for the RAID groups: RAID Group ID: 1 Number of Disks: 6 RA
8、ID Type: RAID 6 Check “Automatically Destroy after Last LUN is Unbound”Expansion/Defragmentation Priority: MediumDisk Selection: AutomaticClick Apply, Yes, OK2)Right click on the RAID Group 1 Bind LUN, Use the following properties for the LUN using the dropdowns:LUN ID: 10 Default Owner: SPA Number
9、of LUNs: 4 LUN size: 10GB Click Apply, Yes, OK, Cancel3)Verify the RAID Group and LUNs have been created.4)Right click the Storage Groups icon and create a Storage Group named “SG_w3k-241”. Click on the Assign Icon under the Storage Management Task Bar. Click Next on the Welcome window. In the “Sele
10、ct Servers” window, check the box for server “w3k-241” and click Next. In the “Select Storage System” window, select the cx1_prod array and click Next.5)In the “Select Storage” window, from the “Available LUNs” section expands SPA and check LUNs 10,11,12,13. This moves the LUNs to the “Selected LUNs
11、” section. Click Next, Finish, Finish.五、实验过程原始记录( 测试数据、图表、计算等)六、实验结果、分析和结论(误差分析与数据处理、成果总结等。其中,绘制曲线图时必须用计算纸或程序运行结果、改进、收获)1) 在创建RAID过程中请问RAID各个级别与磁盘数之间的关系是什么? R0 2个以上或者更多 提高速度 R1 只能2个 损失一个硬盘的容量作为镜像备份 R5 3个或者更多 损失其中一个硬盘的容量作为镜像备份 R10 只能4个 提升速度,损失2个硬盘的容量作为镜像备份2) 创建的Storage Group可否绑定到不同的Server? LUN与主机之间的关
12、系是什么?请说出你的理解. 可以。比如一个阵列柜,主机那边看作是一个Target Device,那为了某些特殊需要,我们要将磁盘阵列柜的磁盘空间划分成若干个小的单元给主机来用,于是就产生了一些什么逻辑驱动器的说法,也就是比Target Device级别更低的逻辑对象,我们习惯于把这些更小的磁盘资源称之为LUN0、LUN1、LUN2什么的。而操作系统的机制使然,操作系统识别的最小存储对象级别就是LUN Device,这是一个逻辑对象,所以很多时候被称为Logical Device。磁盘的属性里就可以看到有一个LUN的值,只是因为你的Disk没有被划分为多个存储资源对象,而将整个磁盘当作 一个LUN来用,LUN ID默认为零,如此而已。注:教师必须按照上述各项内容严格要求,认真批改和评定学生成绩。
