4 1 Introduction The NetApp E-Series storage array is a high-performance storage system that meets demanding performance and capacity requirements without sacrificing simplicity and efficiency. Designed to address wide-ranging solution requirements, its balanced performance is equally adept at supporting high performance file systems, bandwidthintensive streaming applications, and transaction-intensive workloads. And its fully redundant I/O paths, advanced protection features, and extensive diagnostic capabilities deliver the highest levels of availability, integrity, and security. This Lab Guide provides you the opportunity to work with the E-Series storage arrays and the storage management software, and allows you to experiment with different configuration options. It introduces the fundamentals of SANtricity System Manager and its operations. You will notice that this Lab gives you some guidelines to common operations, but does not give you complete, step-by-step instructions that detail every button click. If you have questions about the steps or instructions in any lab, there are several places you can find information: Help section (top right corner) of the SANtricity System Manager interface. Participant guide. Your lab proctor. SANtricity manuals. Firmware/NVSRAM information Product Release Notes. Interoperability/compatibility matrix available through company's website. 1.1 Lab Objectives This lab walks you through different systems configuration options when implementing the an E-Series storage array. The lab shows how easy it is to configure multiple disk protection schemes, allocate storage space, and make on-line changes that outline high availability. This lab is designed to educate storage administrators about the many configuration options they might face during implementation of the storage array in the field. 1.2 Prerequisites You should have a good understanding of the following technologies before you take this lab: 1. Understanding the fundamental differences between a NAS and SAN devices and associated services. 2. Familiarity with the medium connectivity options (i.e., FC, iscsi, SAS, IB). 3. Familiarity with Traditional RAID Groups, and the differences between them and Dynamic Disk Pools. 4

5 2 Lab Environment E-Series Lab Architecture used in this lab. Figure 2-1: Table 1: Table 1 Lab Host Credentials Hostname Description IP Address Username Password JUMPHOST Windows R Demo\Administrator Netapp1! DC1 Active Directory Server Demo\Administrator Netapp1! This lab utilizes the SANtricity Simulator, which simulates the experience of managing a physical E/EF array without the ability to simulate I/O shipment between the Host and the Storage array. The simulator runs locally on the Windows 2012R2 host you see when you first connect to the lab. Note: We recommend that you follow the lab activities in the order in which they are presented by this lab guide. Some exercises in this lab follow a scenario driven approach. The options presented for those scenarios do not necessarily reflect universal best practices, since there are many options that need to be considered for different deployment scenarios. The E-Series arrays have a default set of parameters that get applied to certain LUN structures. In some steps this lab deviates from those defaults to provide insight into what you can do with a real system. Attention: The lab simulator allows HTTP (Port 80) connections for convenience. However, the actual storage arrays will redirect HTTP traffic to HTTPS port 443. In this lab, port is used. 5

6 3 Configure the Storage Array using the Set Up Wizard Initial Setup Use the Setup wizard to configure your storage array, including hardware, hosts, applications, workloads, pools, alerts, and AutoSupport. The wizard prompts you to perform basic configuration tasks, such as naming your storage array, configuring your hosts, selecting applications, and creating pools of storage. Note: You can bypass the Setup wizard by clicking Cancel; however, doing so requires that you manually configure your storage by using the menus in System Manager. 1. Double-click the shortcut titled SANtricty System Manager to launch the System Manger. 1 Figure 3-1: 2. After the application starts, you may be prompted to create a password. Passwords must be between 8 and 30 characters in length and are case sensitive. Use Netapp1! as the password. Enter the password in the two fields shown, then click Set Password. 3. If you are not prompted to create a password, then the userid and password have already been set. Use admin for the userid, and Netapp1! for the password. 6

7 2 Figure 3-2: 4. After setting the password, the Setup wizard launches. Click Next after reviewing the text. 7

8 3 Figure 3-3: 5. Review the shelf details on the next page. Proceed to name your storage array, in this case use the default Array1. Then click Next. 8

17 14 Figure 3-12: 17

18 4 Manually Configure the Storage Array 4.1 Create a Host Although System Manager can automatically detect host connections over a wide variety of protocols, it must be made aware of which host each connections belongs to. The host creation process maps specific host ports to a user-defined host name for easy volume mapping and management. Note: If SMAgent is installed with SANtricity Storage Manager on connected hosts, hosts are created automatically. User intervention is not necessary. 1. On the Home screen, click on the Storage view on the left hand navigation panel. 1 Figure 4-1: 2. Click on the HOSTS tile. 18

19 2 Figure 4-2: 3. Click the Create dropdown button, and select Host. Note: You can also click on the (+) Create Host link to create a host. 19

22 4.2 Create Volumes on Dynamic Disk Pools The dynamic disk pools and volume groups are the top-level units of storage in a storage array: they divide the capacity of drives into manageable divisions. Within these logical divisions are the individual volumes, or LUNs, where data is stored. Volumes are containers in which applications, databases, and file systems store data that is used by the host. 1. Click the Storage view on the left side navigation panel, then click the VOLUMES tile. 1 Figure 4-6: 2. Now click the Create dropdown menu, and select Volume. 2 Figure 4-7: 3. From the dropdown menu, select the Host created earlier, and then Next. 22

25 5 Figure 4-10: 6. Click Next to accept the recommended setup. 25

26 6 Figure 4-11: 7. After review click Finish. A green message box stating Volumes created. should appear at the top. 26

27 7 Figure 4-12: 4.3 Create Volumes on Volume Groups Once a disk pool or volume group is created, it must be logically divided into individual volumes, or LUN s. Each volume is mapped to an individual host, which creates an appropriate file system on the volume and uses it for data storage. 1. Click the Storage view on the left side navigation panel, then click the POOLS & VOLUME GROUPS tile. 27

28 1 Figure 4-13: 2. Click the Create dropdown menu, and select Volume group. 2 Figure 4-14: 3. The Create Volume Group window will display. Use the drop down menus to enter the desired Name in the text field, to select RAID level 5, and to select HDD (SAS) for Drive type. After you select the drive type, browse through the available capactities for the volume group, and select the desired field by clicking on it. Then click Create. 28

29 3 Figure 4-15: 4. A message should appear at the top stating Volume group created. Note: You can also click on Create Volume > in this message to create volumes for the volume group. 29

30 4 Figure 4-16: 5. Click on the Create drop down menu again. Then select Volumes. 5 Figure 4-17: 30

31 6. The Create Volumes window appears. In the Select a host or host cluster dropdown menu, select Host1, then click Next. 6 Figure 4-18: 7. Click Create a new a workload for the created volume. 8. Select the Other option from the dropdown menu. Accept the default name. 9. Click Next. 31

32 7 8 9 Figure 4-19: 10. In the VolumeGroup section of the Create Volumes window, click + Add new volume for the volume group, and enter Volume Name, Reported Capacity, and Segment Size (KiB). 11. Click the checkbox to select all. 12. Click Next after entering the appropriate data. 32

33 Figure 4-20: 13. Review volume configuration for the workload, and click Finish. 33

34 13 Figure 4-21: 14. A green box appears that indicates the volume was created. 34

35 14 Figure 4-22: 4.4 Add Capacity You can add capacity to a pool or volume group dynamically. This next activity will add capacity to the volume group you just created. 1. Select the VolumeGroup you just created, and click Add Capacity. 35

36 1 Figure 4-23: 2. On the Add Capacity screen, select the first drive in the list, and click Add. 36

37 2 Figure 4-24: 3. Click Yes in the confirmation dialog box. 37

38 3 Figure 4-25: 4. A green box appears that indicates the drive was added. 38

39 4 Figure 4-26: 4.5 Remove Capacity Capacity can only be removed from a pool. In this activity, you remove some capacity from Pool_2. 1. Select Pool_2, and then navigate to More > Remove capacity. 39

40 1 Figure 4-27: 2. Select the first drive in the list, and click Remove. 40

41 2 Figure 4-28: 3. Type REMOVE to confirm capacity removal, and click Remove. 41

42 3 Figure 4-29: 4. The green box confirms capacity removal. Also note the capacity decrease from Step 1. 4 Figure 4-30: 42

43 4.6 Delete a Volume If a volume is no longer needed by a host, it can be deleted. Deleting a volume destroys the data in the volume. However, it frees up space in the disk pool or volume group for new volumes to be created and mapped to different hosts. 1. On the Storage screen, click on the VOLUMES tile. 1 Figure 4-31: 2. Click on the volume you wish to delete. Then click the Delete button on the right. 2 Figure 4-32: 43

44 3. Confirm the deletion of the volume: after reading the prompt, type DELETE 1 in the textbox and click Delete. 3 Figure 4-33: 4. Volume deleted will appear in green box at top of screen. 44

45 4 Figure 4-34: 4.7 Enable Security Many drives available for use with E-Series storage arrays support Full Disk Encryption (FDE) or more stringent Federal Information Processing Standard (FIPS) security. Both features prevent a drive from being read or written to without the correct security key, which can be stored internally on the controller or externally on a key management server. Once a security key has been created, encryption can be enabled on a volume group consisting entirely of FDE or FIPS capable drives. 1. Click on the Storage view on the left side navigation panel, then the POOLS & VOLUME GROUPS tile. Figure 4-35: 45

46 2. Select a pool or volume group. Click the More dropdown menu and select the Enable security option. 2 Figure 4-36: 3. Click the Enable security option. If this is the first time to use security, you must create a Security Key before enabling it. Click Create Security Key. 3 Figure 4-37: 4. If you plan to use an external key management server, select the I want to create an external key radio button, click Continue, and complete the required additional steps. For now, select the I want to create an internal key radio button. 5. Click Continue. 46

47 4 5 Figure 4-38: 6. Define a Security Key Identifier and Pass Phrase. Use the default for the key identifier, and MyPassPhrase1! for the pass phrase. 7. Click Create. 6 7 Figure 4-39: 8. Your security key will be displayed. It will also be downloaded to a file via your browser. 47

48 9. Click Close, and then Close again to return to the POOLS & VOLUME GROUPS display. 9 8 Figure 4-40: 10. Now, return to the More dropdown, and select Enable security again. Enter ENABLE to confirm, and click the Enable button. 48

49 9 Figure 4-41: 4.8 Disable Automatic Load Balancing (ALB) The Automatic Load Balancing feature provides automated I/O balancing, and ensures that incoming I/O traffic from the hosts is dynamically managed and balanced across both controllers. When enabled it automatically monitors and balances controller resource utilization, and adjusts volume controller ownership when needed, thereby optimizing I/O bandwidth between the hosts and the storage array. It is enabled by default. 1. Click on the Settings tab on the left side navigation panel, then click the SYSTEM tile. Note: The SYSTEM tile already displays Automatic Load Balancing as Enabled. Figure 4-42: 2. Scroll down until you reach the Additional Settings heading, then click on the Enable/Disable Automatic Load Balancing link. 49

50 2 Figure 4-43: 3. Uncheck the Enable automatic load balancing checkbox, and click Save. 3 Figure 4-44: 50

51 4. Verify that a green box displays that shows load balancing has been disabled. 4 Figure 4-45: 51

52 5 Settings and Support 5.1 Save Storage Array Configuration The storage system configuration file is a script file that contains all of the command line (CLI) commands needed to reconstruct the logical configuration of your storage array. Whenever you make a change to the storage array configuration, be sure to save a new copy of the configuration file so you can recover your array s configuration. Note: This configuration file can only be used to restore the logical configuration of your array; it is not a backup solution for the data on the array. 1. Click Settings on the left side navigation bar of the Home screen, then click on the SYSTEM tile. 2. Under General, click on Save Storage Array Configuration. 3. Select all the checkboxes so you can capture the most complete version of the configuration, then click the Save button to save the file. 4. The file will be in your Downloads folder, and will have the name storage-array-configuration.cfg. In this lab, you will receive a browser warning about downloading this file. Click Keep. 4 Figure 5-1: Note: In a real-world E-Series deployment, the SANtricity CLI or the Enterprise Management Window (EMW), both included with SANtricity Storage Manager, can be used to quickly load a saved configuration onto a similar array. See the productid=61197 for more information. 52

53 5.2 View and Save Storage Array Profile The Storage Array Profile is a human readable report that describes many aspects of your array s configuration. This section will guide you through viewing and saving your storage array s profile. 1. On the Home screen, click on Support in the left side navigation bar, then click on the SUPPORT CENTER tile. 1 Figure 5-2: 2. Under Launch detailed storage array information, click Storage Array Profile. 2 Figure 5-3: 3. Take a moment and browse through the profile in System Manager to familiarize yourself with the types of information available. 4. To save the profile, click Save. The file will be in your Downloads folder with the name storage-arrayprofile.txt. 53

54 5. Click Cancel to return to the Support Center page. 4 5 Figure 5-4: 5.3 View Software and Firmware Inventory SANtricity System Manager provides a way to view all software and firmware versions for your storage array in one place. 1. From the Support Resources tab on the Support Center page, click on Software and Firmware Inventory. 54

55 1 Figure 5-5: From this view, you can see all software and firmware versions organized by Storage Array, Controllers, Power supplies, Drives and IOM (ESM). You can also save to your Downloads folder if you desire. 55

56 Figure 5-6: 56

57 6 Create Snapshots Since you are working with a database workload, first create a snapshot consistency group to maintain database consistency in case a restore is required. Then make sure it is scheduled to automatically create an image on a regular basis. 6.1 Create a Snapshot Consistency Group Snapshot Consistency Groups are ideal for applications that span multiple volumes, such as database applications that store logs on one volume and the database files on another volume. When you add a volume to a consistency group, the Snapshot feature automatically creates new reserved capacity that corresponds to that member volume. You can define a schedule to automatically create a snapshot image of each member volume. 1. Click on the Storage view on the left hand navigation panel, and then click on the SNAPSHOTS tile. 1 Figure 6-1: 2. Click on the Snapshot Consistency Groups tab, and then in the box (+) Create Snapshot Consistency Group. 2 Figure 6-2: 57

58 3. Use the filter search box to filter for SQL volumes. 4. Add all volumes to the consistency group by clicking on the checkbox to the left of the Name. 5. Click Next. Note: For a volume to be eligible, it must not be failed, or a volume copy target Figure 6-3: 6. Reserve capacity is needed to store data and other information related to snapshots. Set your reserved capacity % to meet your environment's needs by using the + or buttons, or typing in the value. To change an individual volume capacity click the Change candidate link below the Edit column. For this lab, accept the defaults, and click Next. Note: If you change the Reserve Capacity %, click the Refresh Candidates button to reflect the changes. 58

59 6 Figure 6-4: 7. Name your consistency group using the text box. Edit the Snapshot consistency group settings, such as automatic deletion, based on a snapshot image limit, and reserved capacity settings. Select the policy for full reserved capacity you desire. Click Finish. 59

60 7 Figure 6-5: 8. In the green box, verify the creation of a new Snapshot consistency group. Then, click Create a snapshot schedule for this group in the green box. 60

61 8 Figure 6-6: 6.2 Create a Snapshot Schedule A snapshot schedule is associated to a snapshot group or consistency group, so reserved capacity might be affected by changes to schedule settings. 1. To select the days you want the snapshots to occur for the consistency group, click each day's check boxes to toggle that day on/off. Check Select all if you desire snapshots for the entire week. Set the Start time and Time zone using the dropdown menus Click Show more options to expand the view. 1 Figure 6-7: 2. Now you can set the snapshots per day, intervals, and start and end dates. Click Create to create the schedule. 61

62 2 Figure 6-8: 3. Verify the new snapshot schedule is created by clicking on the Schedules tab. 62

63 3 Figure 6-9: 6.3 Create an Instant Snapshot Image A snapshot image is a logical copy of volume data, captured at a particular point-in-time. Like a restore point, snapshot images allow you to roll back to a known good data set. Although the host can access the snapshot image, it cannot directly read, or write to it. Here you create the first snapshot image of a volume. 1. Click on the Snapshot images tab, and select Create > Instant snapshot image. 1 Figure 6-10: 2. Select Volume1, and click Next. 63

64 2 Figure 6-11: 3. On the Confirm Create Snapshot Image dialog box, click Create. 64

65 3 Figure 6-12: 4. On the Create Snapshot Image dialog box, accept the default reserved capacity by clicking Next. 4 Figure 6-13: 5. Click Finish to accept the default settings. 65

66 5 Figure 6-14: 6. A green box displays and indicates the snapshot image has been created. 66

67 6 Figure 6-15: 6.4 Create a Snapshot Volume A snapshot volume allows the host to access data in the snapshot image. The snapshot volume contains its own reserved capacity, which saves any modifications to the base volume without affecting the original snapshot image. You can create a Snapshot volume and assign it to a host if you want to read or write snapshot data. The snapshot volume shares the same characteristics as the base volume (RAID level, I/O characteristics, and so on). When you create a snapshot volume, you can designate it as read-only or read-write accessible. In this example, a snapshot volume can be thought of as a logical clone of the database. 1. Click on the Snapshot Volumes tab, and then click Create, or (+) Create Snapshot Volume. 1 Figure 6-16: 2. Use the Filter search to filter snapshot images. In this case, only the previously created snapshot image appears. Select this snapshot image to create a Snapshot Volume, and then click Next. 67

68 2 Figure 6-17: 3. Assign Host1. 4. Select Read / write access mode for the snapshot volume. 5. Click Next Figure 6-18: 6. Accept the default reserved capacity for the snapshot volume. Click Next. 68

69 6 Figure 6-19: 7. Edit the Snapshot Volume settings: setting the Name, enabling SSD Cache, and capacity alerts. 8. For this activity, accept the defaults by clicking Finish. 8 Figure 6-20: 9. Verify that the Snapshot Volume is created. 69

70 9 Figure 6-21: 70

71 7 View Hardware The Hardware view allows you to manage physical components including shelves, controllers, and drives that are installed in the storage array. A shelf is an E-Series enclosure installed in a cabinet or rack that contains the hardware components for the storage array. A controller consists of a board and firmware, controls the drives, and directs the System Manager functions. A drive is an electromagnetic device that provides the physical storage media for the data stored in the storage array. In this section, you will do the following: View the front and back of the physical components as depicted by the Hardware view. Rearrange shelves. Filter drives. View shelf component settings. Turn on and turn off the locator lights for an individual drive, filtered set of drives, or a shelf. 7.1 View Components 1. From the Home page, click on the Hardware label on the left hand navigation panel. 71

72 1 Figure 7-1: 2. Scroll down to the bottom of the page, and click Show all back to easily view all shelf components from the back. Note: You may click Show back of shelf to view the back of an individual shelf 72

76 7 Figure 7-6: 7.2 Rearrange Shelves In the Hardware view, the physical order of the shelves should be detected and accurately depicted by the storage array. If for some reason the physical ordering of shelves and the Hardware view ordering do not match, you may simply move the shelves to display the correct order. 1. Click the Move down arrow on the middle shelf to move it to the bottom-most location. 76

77 1 Figure 7-7: 2. Click the Move up arrow on the bottom shelf to move it back to the default location. 77

78 2 Figure 7-8: 7.3 Filter Drives Drives in the storage array may have different logical and physical attributes. To help you locate specific drive types, the Hardware view has filter controls that limit what is displayed. If all drives have the same physical attributes (for example, all SAS drives), the Show drives that are filter field will not display. If all drives share the same logical attributes (for example, all drives are in Pool 1), the Anywhere in the storage array filter field will not appear. These two fields may be used together, or separately, to filter the drives you want to locate. 1. Click the Show drives that are drop down menu, and select one of the drive types to display. 2. Notice all the drives that are not the selected type are grayed out. 3. To clear the filter criteria, click Clear on the far right of the drive filter controls. 78

84 8 Test Hot Spare Coverage When a disk drive fails, the system needs to be able to handle it without interruption to data access. If you are using pools, there is spare capacity (called preservation capacity) built into each pool to be used to rebuild in volumes in the event of a drive failure. For volume groups, it is best practice to assign one or more global hot spare drives to be used for this same purpose. The array automatically detects many drive problems and if it is not able to correct a given problem, will fail the drive and then will automatically replace the failed capacity with either preservation capacity (in the case of pools) or a hot spare (in the case of volume groups). At other times, you may suspect that a drive has a problem before the system detects it. In such a situation you can manually fail the drive, but the array does not automatically replace it because the array does not know your intentions. In this case you will have to manually initiate the takeover operation. In this section you will do the following: Create a global hot spare. Manually fail a drive in a volume group. Observe the failure notifications. Manually fail another drive with no hot spare coverage. Logically replace the second failed drive. 8.1 Create Global Hot Spare 1. Select the Hardware view, and under Show drives that are select the volume group that you created earlier: 1 Figure 8-1: 2. Note the drives that are highlighted in blue. These are the drives assigned to your volume group. Also, note the shelf. 3. Under Show drives that are..., select Anywhere in the storage array. 4. Now left click on one of the unassigned drives (shown in gray) in that shelf, and select Assign hot spare. 84

85 3 4 Figure 8-2: 5. Click Yes to confirm. 5 Figure 8-3: 6. Note the green bar indicates success, and that the drive you just assigned as a hot spare has turned pink. 85

86 6 Figure 8-4: 8.2 Manually Fail a Drive with Hot Spare Coverage When a disk is in a questionable state or requires replacement for some other reason, it should be pre-failed if possible. If a hot spare is present, System Manager can copy the contents of the drive to the hot spare without degrading the resiliency of the encompassing volume group. 1. Left click on one of the drives in your volume group, and select Fail. 1 Figure 8-5: 2. Make sure the Copy contents of drive before failing box is checked. This will ensure that the data from the drive to be failed is copied to the hot spare before failing the drive. 3. Type FAIL in the box provided in the pop-up window. It is not case sensitive. 4. Then, click Fail to confirm you want to fail the drive. 86

87 2 3 4 Figure 8-6: 5. Note the green success bar that indicates the drive has failed. 6. The array has started copying the data to the hot spare. 5 6 Figure 8-7: 7. When the copy is finished (this takes a couple of minutes), you should see indication that the drive is failed. 8. And the hot spare is in use. 7 8 Figure 8-8: 9. Return to the Home screen, and note that it is indicating a problem with the array. 87

88 10. Click on Recover from 1 problem Figure 8-9: 11. The Recovery Guru comes up, and shows that a drive has failed, along with notes and possible recovery steps. Click on Close to return to the Home page. 88

89 11 Figure 8-10: 8.3 Manually Fail a Drive with No Hot Spare Coverage In the previous step, you used the hot spare when you failed a drive. Now, you will fail a drive and it will have no hot spare coverage because the hot spare is in use. Then you will logically replace the failed drive with an unassigned drive. 1. Return to the Hardware view, select another drive in your volume group, and click on Fail. 89

90 1 Figure 8-11: 2. On the Confirm Fail Drive dialog box, uncheck the Copy contents of drive before failing box. You do this because there is no hot spare assigned to receive the copied data. 3. Type FAIL in the confirmation box. 4. Click on the Fail button Figure 8-12: 5. There are now two failed drives. 90

91 5 Figure 8-13: 6. Return to the Home screen and note that there are several problems. Click on the Recover link to bring up the Recovery Guru. 6 Figure 8-14: 7. The Recovery Guru now shows Volumes Degraded. Click Close to return to the Home screen. 91

92 7 Figure 8-15: 8. Return to the Hardware view, select the drive you just failed, and click on Logically Replace. 92

93 8 Figure 8-16: 9. The Logically Replace Drive dialog box now appears, and shows the drive to be replaced and unassigned drives you can use to replace it. For this lab, select the first one in the list, and click on Replace. 9 Figure 8-17: 10. Note the drive being replaced is now gray, indicating that it will be unassigned when the reconstruction is finished. 11. Note the new drive being added to the volume group. 93

94 Figure 8-18: 12. Once the reconstruction completes, if you return to the Recovery Guru, you can see that the only issues remaining are the failed drives. Reconstruction takes a couple of minutes. 94

95 Figure 8-19: On a real array, you could now physically replace the failed drives, and the storage array would be optimal. The simulator is not able to show this. 95

96 9 View Performance The new SANtricity System manager has an improved ability to show performance information. Storage array level performance can be seen on the Home view but a detailed view is also available. Let s take a look at the detailed performance information. 1. From the Storage view select the Performance tile. 1 Figure 9-1: 9.1 Logical View A logical view of array performance allows filtering of performance statistics by logical units (disk pools, volume groups, and volumes). 1. Initially, you will see the Logical View of performance for the entire array, Array1. There are graphs for both IOPS and MiB/s. Tip: Throughout this section, if the graphs do not display, change the time period for the graph from the default of 1H (1 hour) to 8H (8 hours), and back to 1H again. There appears to be a bug in the simulator. 96

97 Figure 9-2: 2. To filter the information you would like to see, select Volumes, then expand Volume Group. 3. Check Volume Volume1, then click on Refresh Graphs. 4. Also note the possibility to filter on Pools & Volume Groups. Note: Within the simulator not all filters have data provided. 97

98 2 3 Figure 9-3: 5. To compare latency with IOPS on the top graph labeled Latency, select the Compare Latency with drop down menu, and choose IOPS. 98

99 5 Figure 9-4: 9.2 Physical View A physical view of array performance allows filtering of performance statistics by physical components (controllers and drives). 1. Select the Physical View tab. 2. Collapse both the IOPS and MiB/s graphs. This allows you to see the CPU and Headroom graphs. For the physical view it is also possible to filter on the host channels and the drives. 99

100 1 2 Figure 9-5: 9.3 Applications/Workloads View An application/workload view of array performance allows filtering of performance statistics by individual applications or workloads running on the array. 1. Select the Applications & Workloads View tab. This view also provides filtering and comparison options that you can explore. 100

102 10 Access Management SANtricity System Manager has been updated to include a number of new security features. Local role based and external LDAP access control give administrators powerful tools to manage which users have access to an ESeries array and what operations each user can perform. The audit log tracks all activity on an E-Series array. If there is an issue, an administrator can quickly identify what went wrong, when it happened, and which user and access method is responsible Local Role Based Access Control System Manger comes preconfigured with five different user roles (administrator, storage admin, security admin, support admin, and monitor). Each role has different capabilities. For example, the storage admin can create and delete volumes and volume groups, but cannot change security settings. The monitor can view array performance and configuration, but cannot make any changes. The administrator password is set on initial login, but the passwords of other local roles must be set explicitly within the Access Management settings. 1. Click on the Settings label on the left side navigation panel. 2. Click on the ACCESS MANAGEMENT tile. 1 2 Figure 10-1: 3. Click on the Local User Roles tab to view a list of local user profiles and the roles mapped to each. By default, the only usable profile is the admin profile created during initial setup. You must set up a password on each profile before it can be used. 4. Select the Storage admin role. 102

103 5. Click Change Password Figure 10-2: 6. In the Enter your Administrator local user password box enter Netapp1!, and enter Netapp1! for the Storage admin local user password. Then, click Change. 103

104 Figure 10-3: 7. A green box stating Password changed should appear at the top of the screen. 104

105 7 Figure 10-4: 8. Click Logout at the top right corner of the screen. Try signing in to the Storage admin profile. Use storage as the Username, and Netapp1! as the Password. Then click Log In. 8 Figure 10-5: 9. If necessary, click on the Settings label on the left side navigation panel. Notice that the Storage admin profile does not have access to the ACCESS MANAGEMENT or CERTIFICATES tiles. For more information about the capabilities of each of the mapped roles, consult the Learn More link from any tab inside the ACCESS MANAGEMENT tile (while logged in with the administrator profile). 105

106 Figure 10-6: 10.2 Directory Based Access Control SANtricity System Manager also supports role mapping to pre-existing user groups defined on an LDAP server. 1. Log out of SANtricity System Manager and log back in as If necessary, click on the Settings label on the left side navigation panel, and then the ACCESS MANAGEMENT tile. This time, remain on the Directory Services tab. 106

107 1 Figure 10-7: 2. Click on Add Directory Server. 2 Figure 10-8: 3. On the Server Settings tab, add information specific to your LDAP implementation. Enter the following values: 107

108 108 For Domain(s), enter example. For Server URL", enteer ldap://example.com:389. Leave the Bind account (optional) field blank. Uncheck the Test server connection before adding box, as no LDAP server is included with the lab environment. For Search base DN, enter ou=users,dc=example,dc=com. For Username attribute, enter samaccountname. For Group attribute(s) : memberof.

109 3 Figure 10-9: 109

110 4. Click on the Role Mapping tab. Enter cn=sysadmins,dc=example,dc=com for the Group DN, and add an assortment of roles by clicking inside the Roles box and selecting from the drop down list. Add more mappings if desired by clicking on the + Add another mapping link. Note: Each group MUST be given at least the Monitor role in order for a member of that group to be able to access SANtricity Storage Manager 5. At this point in a real configuration you would click Add. Since there is no LDAP server in this lab environment there's no point to doing this, and it will cause your lab to hang for several minutes. 4 5 Figure 10-10: 6. In a production environment with a correctly configured LDAP server, users in mapped user groups would be able to log in to the array with appropriate permissions with a username of the form username@domain, and their organizational password Audit Log The audit log allows users with properly mapped roles to view the activity of all users on an E-Series array. 1. Click on the Settings label on the left side navigation panel, then click the ACCESS MANAGEMENT tile. 110
